The petitioner’s portion of the meeting and scheduled public hearings offer the public two opportunities to present its views to the Council during its meeting. Petitioners The petitioners’ portion of the Council agenda is the first item addressed by the Council following proclamations, certificates of appreciation, regional commission reports and presentations. This part of the meeting gives individuals the opportunity to address the Council on any matter not scheduled for a public hearing. Prior to the meeting, citizens wishing to speak should sign up on the Town’s Web site at https://www.leesburgva.gov/government/mayor- council/current-council-agenda by 4:00 p.m. the day of the meeting or on the signup sheet in the hallway outside of the Council Chamber the night of the meeting. The Mayor will give anyone the opportunity to speak that did not get a chance to sign up. Petitioners’ comments are limited to between three and five minutes at the Mayor’s discretion. Public Hearings Certain Town business items can only be conducted after the Town Council holds an advertised public hearing. Certain major issues affecting the Town’s government can also be scheduled for public hearing at Council’s discretion. Adoption of the Town budget, rezonings, special exceptions and amendments to the Town’s subdivision and zoning ordinances all require a public hearing. Prior to the meeting, citizens wishing to speak at a public hearing may sign up on the Town’s Web site at https://www.leesburgva.gov/government/mayor-council/current-council-agenda by 4:00 p.m. the day of the meeting or on the signup sheet in the hallway outside of the Council Chamber the night of the meeting. The Mayor will give anyone the opportunity to speak who did not get a chance to sign up. Public hearing comments should be limited to the topic of the public hearing and speakers will be given between three and five minutes at the Mayor’s discretion. If you wish to speak at more than one public hearing, you must sign up for each hearing separately. Decorum A person addressing the Council as a petitioner, or during a public hearing, should advance to the podium when recognized by the Mayor and state and spell his or her name for the purpose of closed captioning. If comfortable doing so, speakers should provide their address for the record. Persons should also indicate whether they are representing anyone other than themselves. Decorum will be maintained. Statements, which are demeaning or defamatory to members of the public, the staff or the Council, are inappropriate and out of order. OTHER COUNCIL MEETINGS Work Sessions Council meets twice per month, or more often as necessary, to discuss items that are placed on the agenda at the desire of the majority of Council present. Items are typically discussed at a meeting at least two weeks into the future but items may be added in a shorter time frame in accordance with Council’s adopted rules and procedures. Closed Sessions Under certain circumstances, the Virginia Freedom of Information Act permits the Town Council to meet in a session where the public is excluded. This may be a discussion of personnel matters, legal matters, the acquisition or sale of property and other selected topics. The Council can only go into closed session to discuss topics specifically exempted from the open meeting requirements and all closed sessions must be properly noticed and appropriate Code sections cited as to the specific statutory authority to go into closed session. The notice must also include the general topics to be discussed. Only those matters in the adopted motion to go into closed session can be discussed and members in attendance must certify that only those topics were discussed when they return to an open session. TOWN COUNCIL AGENDA MATERIALS Council agenda materials are available to citizens by end of day Wednesday immediately preceding the set of Council Meetings.

LaFollette, Director of Public Works and Capital Projects Keith Markel, Deputy Town Manager Russell Seymour, Economic Development Director Council Action Requested: Work Session discussion to review the findings of the Liberty Parking Lot remediation study with Town staff and consultant team. Staff Recommendation: Town Council should determine the long term intended use of the Liberty Street Parking lot before deciding on a course of action related to any potential site remediation. Commission Recommendation: None at this time Fiscal Impact: The remediation study and order of magnitude cost estimate prepared by WSP USA Environment and Infrastructure Inc. (WSP), indicates that the cost for full site remediation of the Liberty Parking Lot is $16.9 million. This dollar value includes project management costs of 10% and a contingency of 30% which are both appropriate for this level of estimate. The estimate prepared for the full site remediation totals $16.9 million. The estimate includes everything from design plans and permitting, building demolition, further site testing and investigation required if the Town decides to go forward with the VRP, permitting, waste disposal of both hazardous and non-hazardous materials, construction dewatering, minimizing community impacts, restoration of haul roadways, contingency and management costs. The assumptions on quantity of material and classification of hazardous vs. non-hazardous are based on the sampling and testing done on the site and seem reasonable based on the information presented. Partial remediation of the site is also an option and pricing would be less than the full $16.9 million estimate. The current remediation study was contracted with WSP in the amount of $130,961. One additional change order for $3,415 has been authorized for additional led testing on the soil samples retrieved during the drilling, for a total contract price with WSP of 134,376. Based on the work completed thus far and if the Town decides to move forward with remediation of the site, additional testing to further quantify the hazardous material and surface water and sediment testing of Town Branch would be required and that additional testing is estimated to cost an additional $125,000. Work Plan Impact: If the Town were to move forward with the site remediation of the Liberty Parking Lot, it will have a significant work plan impact for the design of the remediation, coordination with the adjoining properties, construction document preparation, and project management of the actual remediation project. The magnitude of the project would have to be taken 4 Item a. Liberty Parking Lot – Site Remediation October 23, 2023 Page 2 into account relative to the other projects already scheduled in the currently approved 2024-2030 Capital Improvements Program. Town Plan Impact: One of the Legacy Leesburg guiding principles is to look at Character and Authenticity in order to retain the historic core of Leesburg and to provide a high-quality brand and sense of place that stretches through the entire community. The Liberty Lot site is located within the downtown old and historic district and is adjacent to the downtown commercial district. This site could support quality redevelopment. In addition, Strategy 5.2.7 addresses environmental contamination issues related to the remediation of soil and groundwater contamination and the investigation into and taking the necessary steps to identify the potential and suspected contamination issues which this proposed study of the Liberty Lot will do. Chapter Four: Place Based Recommendations has identified the Liberty Street Lot as Opportunity Area #6 as an example of a downtown infill redevelopment opportunity. Executive Summary: At the March 28, 2023 Council meeting, a contract with WSP USA Environment & Infrastructure Inc. (WSP) was authorized to perform a remediation study and to prepare an order of magnitude cost estimate for the remediation of the dump material located under the Liberty Street Parking Lot. Past uses of the Liberty Street Parking Lot property include the site serving as a municipal dump on the southern half of the property from the 1940s to the mid-1950s. Currently the site is used as a public parking lot along with a satellite location for the Department of Public Works for office and storage of materials. In 2003, the Virginia Department of Environmental Quality (DEQ) performed a Site Screening Report (SSR) as part of their Brownfields Program. The agency evaluated the history and the analytical data related to the site. The SSR presented the results of the Brownfields site assessment conducted under the U.S. Environmental Protection Agency (EPA) Targeted Brownfields Assessment (TBA) Program, at no cost to the local jurisdiction with the ultimate goal of promoting cleanup and redevelopment of the site. With the changes in regulations since the 2003 SSR was completed, a further and more detailed remediation study was required to further determine the types of materials and the costs of waste hauling and disposal. As part of the Town’s 2023 study, WSP performed the drilling activities and ground water sampling between April 2023 and the middle of August 2023. The final report and estimate are attached as Attachments #1 and #2. The results of the investigation developed the following findings:  Materials consistent with a historic landfill were identified under Liberty Lot to depths of up to 20 feet below grade. The materials encountered in the drilled shafts and soil borings were relatively consistent in nature, comprised of soil and refuse material consistent with landfilling operations.  Complete removal of refuse material would generate approximately 35,000 cubic yards of combined soil and refuse material. 5 Item a. Liberty Parking Lot – Site Remediation October 23, 2023 Page 3  Soil samples from the borings and stockpile contain PAHs (petroleum HCs) concentrations that exceed residential SSLs. Arsenic, lead and cadmium exceeded residential SSLs. Lead concentrations exceed industrial SSLs.  Soil samples from the stockpile contained leachable lead concentrations that exceed hazardous waste criteria, and the stockpile must be managed as a hazardous waste and shipped to a facility permitted to accept hazardous waste.  Soil samples from the Drilled Shafts contained total lead concentrations ranging from 150 mg/kg to 4,000 mg/kg. total lead in seven samples exceeded industrial SSL of 800 mg/kg, and total lead in five samples exceeded the residential SSL.  Soil samples from the Drilled Shafts contained leachable lead at concentrations ranging from 2.3 mg/L to 84 mg/L. TCLP lead exceeded the hazardous waste threshold of 5.0 mg/L in 19 of the Drilled Shaft samples analyzed.  Groundwater samples collected at the site contained detectable concentrations of PAHs, lead, and PFAS which exceed drinking water standards or screening levels.  Nine PFAS analytes were detected in the Stockpile – 3 soil samples analyzed, at a maximum concentration of 660 ng/kg (PFOS).  The source of the PFAS detected in soil and groundwater samples is not known.  Although constituents have been detected in soil and groundwater samples at concentrations greater than criteria and screening levels, no action is required if soil and refuse material remain in place. Background: Due to the history on the property, primarily the municipal dump that was closed in the mid-1950’s, and potential redevelopment interest, Council directed staff to engage an engineering firm with environmental and geotechnical experience in investigating old municipal landfills. WSP Environment & Infrastructure Inc. (WSP) was awarded a contract for the site investigation that included geophysical testing, drilling, water and soil sampling. This work was performed between April and August of 2023. The first phase of the site investigation included geophysical testing that included electromagnetic (EM) and ground penetrating radar (GPR). These tests were used to help identify the extent of the buried landfill material and to determine if there were any underground storage tanks, suspected buried metal and non-metal debris. See Attachment #3. This survey result indicated a relatively homogeneous material in the subsurface and did not identify any large features, such as underground storage tanks. The second and third phases of the site investigation included drilled shafts, soil borings and groundwater monitoring well installation. Soil sampling was completed with all of the drilling. Locations for the drilling were based on the review of the geophysical survey that was completed in phase one. The results of the soil sampling indicates that there is a significant portion of the material that would need to be removed for full site remediation that would be classified as hazardous material based on the levels of petroleum hydrocarbons, lead, cadmium, etc. that were determined by the laboratory analysis. Based on what was found through the soil testing, that the former landfill material contained leachable lead concentrations that exceed hazardous waste criteria, the estimate for remediation assumed that a large portion of the materials would have to be managed as a hazardous waste and 6 Item a. Liberty Parking Lot – Site Remediation October 23, 2023 Page 4 shipped to a facility permitted to accept hazardous waste. The estimate included with the report is divided into phases including Plans & Permits, the Voluntary Remediation Program, Site Preparation, Remediation, Closeout and Reporting. In general, the estimate is broken down as follows: DESCRIPTION COST Plans and Permits $325,000 DEQ Voluntary Remediation Program $209,500 Site Preparation $139,600 Remedial Action: Assumes: 20% of waste material managed as non-hazardous 55% of waste and soil material managed as RCRA Hazardous 25% of material segregated out for disposal at Loudoun County Landfill $11,360,933 Closeout and Reporting $54,000 Management and Consulting: Assumes Project Management as 10% of the subtotal Staging Area Rental Contingency of 30% of subtotal $4,831,613 TOTAL $16,865,647 Town staff and the consultant team met with DEQ representatives to discuss the options that the Town has relative to remediation of this site. The first discussion point was that if the site was left as a parking lot there is nothing that the Town would need to do. If the Town should decide to remediate part or all of the property, the Virginia Voluntary Remediation Program (VRP) is something that should be considered. The VRP is a voluntary program administered by DEQ that is designed to help property owners remediate contaminated sites. The regulations and guidance that have been released by DEQ outline the process for enrolling in the VRP, completing the investigation and remediation activities, and obtaining a Certificate of Satisfactory Completion (CSC) for the contamination of interest. The CSC would be a critical item for private sector development partners, since the immunity provided by a CSC would apply not only to the Town as the current owner but would run with the land and apply to all future property owners. 7 Item a.

Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 5 Executive Summary On behalf of the Town of Leesburg WSP USA, Inc. conducted a Site Investigation of the Liberty Street Parking Lot to characterize the nature of the waste materials remaining from when the southern portion of the property was used as a municipal landfill from the 1940s to the mid-1950s. Waste materials were dumped and covered with soil, presumably moving from north to south across the Site. The accumulation of waste materials raised the Site elevation considerably. This field investigation was conducted in several phases from April to August 2023. A geophysical investigation consisting of an electromagnetic (EM) and ground penetrating radar (GPR) survey was conducted to locate potential USTs and the limits of buried debris. The survey found a relatively homogeneous mix of soil and debris and did not identify any large features, such as underground storage tanks. Following completion of the geophysical survey, WSP performed the following tasks:  WSP advanced eight drilled shafts within the footprint of the delineated landfill material and collected a total of 27 soil samples from various depths, biased towards soil with evidence of staining, odors and/or VOC detections.  WSP also collected composite samples of the combined debris and soil from all eight drilled shafts to characterize the material for disposal.  WSP advanced five soil borings and converted four of the borings into groundwater monitoring wells. WSP collected a total of ten soil samples from the five soil borings.  Groundwater samples were collected from the four monitoring wells on June 29, 2023. The analytical results for the drilled shaft and soil boring soil samples were compared to the Virginia Voluntary Remediation Program (VRP) Soil Screening Levels (SSLs). Several classes of compounds were detected at concentrations greater than screening levels:  Volatile organic compounds: naphthalene and trimethylbenzenes  Semivolatile organic compounds: naphthalene, benzo(a)pyrene, 2-chlorophenol, nitrobenzene and/or 2-methylnaphthalene  Metals: Lead, arsenic and cadmium  PCBs: Aroclor 1254  Pesticides: 4,4'-DDD  Leachable lead exceeded the hazardous waste threshold of 5.0 mg/L in 19 of the Drilled Shaft samples analyzed. The groundwater analytical results were compared to VRP groundwater screening levels (SLs). Several classes of compounds were detected at concentrations greater than screening levels:  SVOCs: naphthalene and 2-methylnaphthalene 13 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 6  Metals: Lead  PFAS: PFOS and PFOA Materials consistent with the former landfill were identified to depths of up to 22 feet below grade. The materials encountered in the drilled shafts and soil borings were relatively consistent in nature, comprised of soil and refuse material consistent with landfilling operations. If the soil and refuse material were excavated for disposal, most of the mixed soil and refuse would be classified as a hazardous waste because the leachable lead concentration exceeds the regulatory limit. This will significantly increase the cost. Further investigation of the soil and refuse material may be able to develop a remediation plan that distinguishes between hazardous and non-hazardous waste materials to the satisfaction of disposal facilities and VDEQ. ‘Soil stabilization’ is often used to reduce leachable metals concentrations in contaminated soil on brownfield sites so the soil can be managed as non-hazardous waste. This process mixes Portland cement, lime or other additives into soil to reduce leaching of lead and other metals. Disposing of the soil and debris as a non-hazardous waste would also reduce potential long term liability. A treatability study would be necessary to accurately estimate the effectiveness and potential cost savings from on-site stabilization. There would be significant constraints on remediation, including residential housing to both the east and west, limited road access, and the Town Branch stream bordering the site to the South. Excavation, screening and loading of soil and waste will generate odor, dust and noise. Soil stabilization or using screens to separate debris for disposal would generate even more dust. Significant community outreach would be needed and strict monitoring and controls would be required to conduct the work without impacting adjacent properties. The Site appears to be eligible for the Virginia VRP, which would provide a pathway to obtain state regulatory approval of future remediation, limit potential liability for the Town and any future owners of the Site, and have value for any private investment group responsible for building construction. Remediation of the Site under the VRP would potentially require conducting additional soil, groundwater and surface water sampling, including analyzing surface water and sediment samples from Town Branch for PFAS compounds. Remediation of the site under the VRP would not necessarily require complete removal of refuse material. Leaving material in place would lower excavation costs significantly but results in the loss of parking space. There are local and regional examples of construction of former landfill areas, and evaluation of available methods to support foundation loads may prove beneficial. If refuse material is left in place during site redevelopment, institutional and engineering controls would be required. If the site is not redeveloped, no additional investigation or sampling is required at this time. 14 Item a.

Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 8 1.0 INTRODUCTION WSP USA Earth and Environment (WSP) conducted a Site Investigation of the Liberty Street Parking Lot (the “Site”), located at the southern terminus of Liberty Street in Leesburg, VA. The investigation was conducted at the request of the Town of Leesburg to characterize the nature of the waste materials within a former landfill beneath the Site. Information gathered from this investigation will support decision making by the Town related to potential redevelopment of the Site. The investigation was implemented in general accordance with the Liberty Street Lot Landfill Investigation & Characterization Proposal (“Proposal”) prepared by WSP and submitted to the Town on March 8, 2023. This Site Investigation Report includes Site background information, a description of field investigation activities, a summary of results, and conclusions and recommendations. 2.0 SITE BACKGROUND 2.1 Site Location The Site is located at south end of Liberty Street, in the Town of Leesburg, Virginia (see Figure 1). The lot is situated on the southern portion of the Town and is surrounded by commercial businesses, residences, and a public park. The Site is accessed by Liberty Street from the north and a driveway on the southeastern corner of the site which joins the intersection of Wirt Street and South Street SW. 2.2 Site Description The Site is a roughly 1.95-acre rectangular-shaped lot and currently serves as a parking lot for public and Town-owned vehicles (Figure 1). Two cinder-block buildings on the northern portion of the Site are used by the Town as a sign shop and for equipment storage. The Site topography slopes gently to the south and is defined by relatively steep slopes on the eastern, western, and southern sides. The Site slopes sharply to the west into a wooded area with a drainage ditch, to the east toward Wirt Street and to the south toward Town Branch. The adjacent properties to the west, east and south are within the 100-year floodplain. The Site is not within the 100-year floodplain due to its higher elevation. 2.3 Site Operations and History Information related to the Site history was provided in the Brownfields Site Screening Report (WPI, 2003) prepared by WPI and Virginia Tech. The Site was reportedly used as a water distribution facility in the 1930s. Two water supply wells, 360 feet deep and approximately 152 feet deep, were subsequently abandoned. The southern portion of the property was used as a municipal landfill from the 1940s to the mid-1950s. Municipal landfill materials were dumped and covered with soil, presumably moving from north to south across the Site. The accumulation of waste materials raised the Site elevation considerably as the 16 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 9 landfill was formed. From the mid-1950s to mid-1980s the property was used as a public works storage and equipment maintenance facility. During this period, three underground fuel storage tanks (USTs) and aboveground dispensers were used by the Town. From the late 1980s to present the property has been used as a parking facility and equipment storage for the Town. The former USTs consisted of a 550-gallon diesel tank and two, 1000-gallon gasoline tanks. These tanks were installed by the Town after the landfill ceased operation, and it is unknown when the Town stopped using the tanks. The USTs, associated piping, and dispensers were excavated and removed from the site in June 1990. Investigation activities associated with the former USTs are discussed in Section 2.5. 2.4 Local Geology and Hydrogeology Runoff from the Site drains downslope to the east, south and west and eventually into Town Branch. Stormwater ditches on the east and west property boundaries drain to Town Branch. Town Branch flows to the south-southwest into Tuscarora Creek and ultimately discharges to the Potomac River. The elevation of the Site reflects the accumulation of landfill materials that were placed in 1940’s and 1950s. The thickness of these fill materials exceeds 20 feet. The Site is underlain by the Triassic age Leesburg Member which consists of crudely bedded carbonate conglomerate with lower Paleozoic limestone and dolostone in a pebbly sandstone and calcareous siltstone matrix (Southworth, et al., 2006) A previous report (WPI, 2003) identifies two municipal water supply wells (Royal Street No. 1 and No. 2) that previously existed on the northern portion of the Site and another well (Fireman's Well) that was located immediately west of the site. According to the WPI report: Royal Street No. 1 was drilled prior to 1938 to a depth of 152 feet, produced 35 gallons per minute and was abandoned in 1989. Royal Street No. 2 was drilled prior to 1938 to a depth of 360 feet, produced 60 gallons per minute and was abandoned in 1989. The Fireman's Well was drilled in 1954 to a depth of 296 feet, produced 150 gallons per minute and was abandoned in 1987. One residence near the site (Mc Vay Well) obtained drinking water from a private well until the summer of 2002, when that residence connected to public water. Reportedly, groundwater was not encountered in the soil borings advanced to a maximum depth of 20 feet below grade during the 2003 investigation. A perched water zone was encountered at 8 feet below grade in one of the 2003 borings. Loudoun County’s GIS database identifies two wells on the adjacent property east of the Site. One of the wells (WWIN-1111-0056) is listed as abandoned and one well (WWIN- 17 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 10 1981-0310) is identified as active. The active well is listed as an individual water well with a depth of 300 feet. 2.5 Previous Investigations In June 1990, soil sampling was conducted as part of the UST removal activities. One soil sample was collected from under each of the three USTs; however, only the one sample exhibiting the highest photoionization detector (PID) reading was submitted to a laboratory for analysis. The soil sample contained 1,860 mg/kg of total petroleum hydrocarbons (TPH). To investigate the extent of the soil contamination, six soil borings and two hand auger borings were advanced in October 1990. Samples from the borings were laboratory analyzed for TPH using EPA Method 418.1, and benzene, toluene, ethylbenzene, and xylene (BTEX) using EPA Method 618. Results from the October 1990 sampling event indicated concentrations of BTEX below the quantitation limits in all five samples. TPH was detected at a concentration of 509 mg/kg in a sample collected from fill material. The sample results were submitted to the Virginia Department of Environmental Quality (VDEQ). VDEQ requested that additional samples by collected to further delineate the horizontal extent of the TPH contamination. In June 1992 four additional hand auger borings were advanced for the collection of soil samples. Five soil samples were submitted to a laboratory for analysis of TPH. The maximum TPH concentration was 57 mg/kg, which is below the 100 mg/kg action level for UST closure. In December 1992 groundwater from a nearby residential well was sampled and analyzed for TPH and BTEX. The analytical results were below the detection limits for the reported analytes. These results were submitted to VDEQ. On July 13, 1993, VDEQ issue a regulatory case closure letter for the UST site, stating that VDEQ did not consider residual contamination at the Site to be a threat to human health or the environment. In 2003, WPI, in conjunction with Virginia Tech, conducted a brownfields environmental investigation and prepared a brownfield site screening report for VDEQ at the Liberty Street Lot. Soil borings were advanced to depths of approximately 20 feet below grade for soil sample collection. Soil sample analysis identified concentrations of metals and polynuclear aromatic hydrocarbons (PAHs) above VDEQ Tier II residential and industrial screening levels (VDEQ used industrial to refer to all non-residential land use). Lead was detected in 12 of the soil samples at concentrations ranging from 51.7 mg/kg to 1,010 mg/kg. High concentrations of methane gas were encountered during the advancement of several soil borings however the methane levels dropped quickly after a short period of venting. Groundwater was not encountered in the soil borings. The report concluded that risks could be managed by maintaining the cover at the site to eliminate soil exposure. The 2003 investigation included the collection and analysis of sediment samples from an adjacent stormwater drainage ditch and downgradient Town Branch. Analysis of sediment 18 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 11 samples identified concentrations of various PAHs, other semi-volatile organic compounds, and pesticides, with concentrations of benzo(a)pyrene that exceeded Tier II screening levels. 3.0 FIELD INVESTIGATION The field investigation was conducted in several phases from April to August 2023. The following describes the process of data collection and observations during the various field investigation phases. 3.1 Geophysical Survey WSP subcontracted with Forrest Environmental Services, Inc. (FES) of Oak Hill, VA to conduct a geophysical survey of the Site. The geophysical investigation was conducted on April 24th and 25th, 2023 and consisted of an electromagnetic (EM) and ground penetrating radar (GPR) survey to locate potential USTs and suspected buried metal and non-metal debris. Vehicles were removed from the parking lot in phase, which allowed FES to conduct their surveys with limited interference. Figure 2 identifies the extent of buried material and debris within the landfill. FES concluded that the response from the EM and GPR surveys was consistent with buried landfill material with a greater concentration of potential ash in the southern portion of the survey. The survey results illustrate a relatively homogeneous material in the subsurface and did not identify large features, such as underground storage tanks. The geophysical report from FES is provided as Appendix A. 3.2 Drilled Shaft Installation and Sampling Following completion of the geophysical survey, WSP identified eight proposed locations for drilled shafts within the footprint of the delineated landfill material. WSP subcontracted with H&H Concrete Construction, Inc. (H&H) from Mt. Airy, MD to advance drilled shafts into the landfill. On May 8, 2023 H&H mobilized an excavator and support equipment to the site to complete the eight drilled shafts (DS-1 through DS-8) over a two-day period. The drilling locations were spaced out across the Site to provide a representative sampling of the materials from within the landfill (Figure 3). After removing the asphalt from the proposed locations, H&H advanced drilled shafts using a rotary auger attachment to the excavator. The drilled shafts were approximately 1-foot in diameter and extended to a maximum depth of 23 feet below grade. The recovered soil, debris and waste materials were inspected and screening with a multi- gas meter capable of measuring volatile organic compounds (VOCs), lower explosive limit (LEL), hydrogen sulfide and methane. Gas measurements were also recorded at the top of each drilled shaft and at depth using plastic tubing that was connected to the meter and lowered down into the shafts. The highest VOC measurement (94 parts per million) was recorded at a depth of approximately 15 feet in DS-2. Methane concentrations at 21% and 54% were identified at depths of 19 feet in DS-2 and 18 feet in DS-1, respectively. VOC and methane concentrations dissipated as the shafts remained open. 19 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 12 WSP collected soil samples from each drilled shaft based on visual observations and screening results. WSP collected a total of 27 soil samples from the shafts, including one duplicate sample. The samples were collected from various depths and were biased towards soil with evidence of staining, odors and/or VOC detections. Additionally, WSP combined the soil from all eight borings to generate a single composite sample (“Combined Drilled Shafts”) that was considered representative of the full investigation area. The recovered soil and waste materials were stockpiled in a corner of the parking lot. The soil and waste materials were placed on plastic sheeting, covered, and surrounded with hay bales to prevent soil from running off the stockpile area. On May 9, 2023, WSP collected two, eight-point composite samples (“Stockpile 1” and “Stockpile 2”) of the soil from the stockpile and analyzed the samples for various constituents required for landfill acceptance. On August 24, 2023, WSP collected an additional, eight-point composite sample (Stockpile- 3) of the soil from the stockpile for analysis of Per-and polyfluoroalkyl acids (PFAS) compounds, total lead and TCLP lead. Soil samples were collected in laboratory-supplied sample containers and dropped off to the analytical laboratory for analysis of the following: Drilled Shaft soil samples:  Target Analyte List (TAL) VOCs using EPA Method 8260  TAL Semi-volatile organic compounds (SVOCs) using Method 8270  RCRA 8 Metals using EPA Method 6010  Polychlorinated biphenyls (PCBs) using Method 8082  Pesticides using EPA Method 8081, and  Herbicides using EPA Method 8151  Total and TCLP Lead EPA Method 6010 Composite Samples (Drilled shaft and stockpile):  Same analyte list as above, plus  VOCs, SVOCs, RCRA metals, pesticides and herbicides using the toxicity characteristic leaching procedure (TCLP)  Paint Filter test for free liquids  Total organic halides by EPA Method 9023  BTEX by EPA Method 8260  TPH in the gasoline range (GRO) and diesel range (DRO) by EPA Method 8015  Hexavalent Chromium by EPA Method 3060A (stockpile samples only)  PFAS by USEPA Method 8327 (Stockpile-3 sample only) 20 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 13 After the collection of the soil samples was completed, the drilled shafts were backfilled with #57 crushed stone to approximately 4-inches below the surface. The stone was compacted in the upper 4 feet with the use of the excavator bucket and hand tools. After all the shafts were backfilled with stone, H&H placed hot mix asphalt patch over each location to match the parking lot grade. GPS locations for each drilled shaft were recorded (Figure 3). 3.3 Soil Borings and Well Installations Tidewater, Inc. of Elkridge, MD (Tidewater) was retained by WSP to advance soil borings and install monitoring wells in accordance with WSP’s proposal. Five soil borings were advanced by Tidewater utilizing a Geoprobe™ track-mounted, direct-push technology (DPT) drilling rig equipped with hollow stem augers. WSP provided oversight of drilling activities The location of the soil borings, which were designated as SB-1, SB-2, SB-3, SB-4, and SB-5 are shown on Figure 3. Soil borings were advanced to depths ranging from 23.0 feet to 33.0 feet below grade. Soil cuttings generated during installation of the soil borings were placed in the stockpile with the drilled shaft materials. Soil samples were collected continuously from each soil boring using a 4-foot Macro core sampler for visual classification and volatile organic compound (VOC) screening. A representative portion of soil from each sample interval was placed in new, re-sealable plastic bag and VOCs in the headspace were measured using a calibrated photoionization detector (PID). Generally, measured VOC concentrations in soil were below background levels, with the exception of soil from the following:  SB-3: 8-12 feet below grade - 19.8 parts per million by volume (ppmv)  SB-5: 8-12 feet below grade – 310 ppmv Soil samples were collected in laboratory-supplied sample containers and dropped off to the analytical laboratory for analysis of the following: Soil Boring soil samples:  TAL VOCs using EPA Method 8260  TAL SVOCs using Method 8270  RCRA Metals using EPA Method 6010  PCBs using Method 8082  Pesticides using EPA Method 8081, and  Herbicides using EPA Method 8151 Following the collection of soil samples, GPS locations for each soil boring were recorded. Tidewater installed groundwater monitoring wells at four of the five borehole locations (see Figure 3). Well construction details are provided in the following table. 21 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 14 Table 1: Well Construction Details Well ID Total Depth (feet below grade) Diameter/Material Screened Interval (feet below grade) GW-1 22.5 2-inch PVC Sch 40 7.5-22.5 GW-2 28.5 2-inch PVC Sch 40 13.5-28.5 GW-3 27.5 2-inch PVC Sch 40 12.5-27.5 GW-4 27.5 2-inch PVC Sch 40 12.5-27.5 Following installation, each well was developed by purging a minimum of five well volumes with a submersible pump. Recovered groundwater was placed in drums, which were sealed, labelled, and placed near the soil stockpile. WSP surveyed the top-of-casing elevation for each monitoring well relative to a common site datum, which was arbitrarily assigned an elevation of 100 ft. 3.4 Well Gauging and Groundwater Sampling Groundwater samples were collected from the four monitoring wells on June 29, 2023. Prior to sampling, depth to water was measured from each well with an interface probe. The wells were sampled using a peristaltic pump and low-flow purge/sample methodology. Dedicated tubing was used for each groundwater sample. Groundwater was pumped through a flow-through cell which allowed for measurement of pH, temperature, specific conductivity, dissolved oxygen, and turbidity parameters with a Horiba U-52. Groundwater samples were collected after measured parameters were within 10% variance in three consecutive tests. Residual purge water was placed in a drum, labeled and staged near the stockpile. Five groundwater samples (including one duplicate) were packaged in coolers with ice and shipped to the analytical laboratory with chain-of-custody for analysis of the following:  VOCs using EPA Method 8260  SVOCs using Method 8270  TPH-GRO and TPH-DRO by EPA Method 8015  RCRA 8 Metals using EPA Method 6020  PCBs using Method 8082  Pesticides using EPA Method 8081  Herbicides using EPA Method 8151, and  Per- and Polyfluoroalkyl Substances (PFAS) by EPA Method 8327 22 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 15 Additional well gauging events were conducted in August 2023. 3.5 Investigation Derived Waste Investigation derived waste (IDW) generated during the sampling activities included soil and debris from the drilled shafts and soil borings and groundwater from well development, purging and sampling. Soil, debris and waste materials generated as cuttings from the drilled shaft and soil borings were placed in a stockpile on the northeast corner of the Site and covered with plastic. PVC pipe, tubing, PPE, and sampling supplies were double-bagged as municipal solid waste and disposed in a trash dumpster. WSP will coordinate with the Town for removal of the stockpile and drums to an approved facility. 4.0 SUMMARY OF RESULTS The results of the investigation are discussed in the following sections. Soil and groundwater analytical results are presented in data tables and summarized in the report text. These data tables provide the results for only those compounds that were detected above the laboratory reporting limits. Soil sample laboratory analytical reports are provided as Attachment B. Groundwater sample laboratory analytical reports are provided as Attachment C. 4.1 Site Specific Soil Conditions and Hydrogeology Subsurface materials encountered in the drilled shafts and soil borings were relatively homogeneous and indicative of municipal landfill materials. Soils, consisting mostly of dark brown, silty clay with sand, was the most predominant material encountered in the drilled shafts and borings. Soil was mixed with fragments of asphalt, brick, glass, metal, paper, and wood. Identifiable waste materials were fragmented and decayed. Soil boring refusal was encountered at depths ranging from 22 feet below grade (SB-1) to 32 feet below grade (SB- 5). Results of the VOC screening were negative (0.0 ppmv) for all intervals in three of the borings, SB-1, SB-2, and SB-4. In the other two soil borings PID readings ranged from 0.2 to 310.0 ppmv. There were odors observed in the soil samples from SB-3, SB-4, and SB-5. Soils transitioned from moist to wet at depths of approximately 20 to 32 feet below grade. Table 2 provides depth to water measurements for the groundwater monitoring wells on three occasions. No separate-phase petroleum product was identified on the water table during the gauging events. The depth to groundwater (DTW) in the monitoring wells ranged from 15.84 feet below the top of casing (TOC) in well GW-4 to 18.45 feet below TOC in well GW-1. Groundwater elevations were calculated for each gauging event relative to the site- specific survey datum. 23 Item a.

TCLP lead exceeded the hazardous waste threshold of 5.0 mg/L in 19 of the Drilled Shaft samples analyzed. 4.3 Soil Sample Laboratory Analytical Results – Composite Samples Laboratory analytical results for the composite samples collected from the combined drilled shaft samples (“Drill Shafts”) and the soil stockpile (Stockpile-1, Stockpile-2, Stockpile-3) are presented in Table 9 (VOCs), Table 10 (SVOCs), Table 11 (Metals and other inorganics), Table 12 (TCLP and waste acceptance criteria), and Table 13 (PFAS). The analytical results for the composite soil samples presented in Tables 9, 10 and 11 are compared to the Virginia Voluntary Remediation Program (VRP) Soil Screening Levels (SSLs) for residential and industrial setting. The SSLs are based on the Virginia Unified Risk Assessment Model (VURAM) 3.2.1, Virginia Department of Environmental Quality, August 2022. The composite soil sample results in Table 12 (TCLP analytes plus Loudoun County Landfill waste acceptance criteria) are compared to Virginia “clean fill standards as specified in the Administrative Code VAC20-81-660.

The VRP is a voluntary program that is designed to help property owners remediate contaminated media to protective health-based action levels. The regulations and associated guidance that have been released by the VDEQ outline the process for enrolling in the VRP, completing investigation and remediation activities, and obtaining a Certificate of Satisfactory Completion (CSC) for the contamination of interest. The CSC will be a critical item for private sector development partners, since the immunity accorded by a CSC would apply not only to the Town as the current owner, but will run with the land and apply to future property owners. Completing the VRP process would require the following steps: 1. Eligibility Determination 2. Program Enrollment 27 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 20 3. Prepare a Voluntary Remediation Report, including Site Characterization Report and Risk Assessment, and submit to VDEQ for review and approval 4. Establish remediation goals 5. Prepare Remedial Action Plan and submit to VDEQ for review and approval 6. Conduct remediation 7. Prepare Demonstration of Satisfactory Completion and submit to VDEQ for review and approval 8. Public notice and public participation 9. VDEQ issues Certificate of Satisfactory Completion A more detailed outline of the VRP process is provided in Attachment D. The following sections discuss the potential application of three key VRP requirements for the Site. Eligibility Determination: During a call with VDEQ VRP staff on September 20, 2023, Meade Anderson of VDEQ indicated that the Site would be eligible for the VRP based on VDEQ’s knowledge of the site history. Nevertheless, a formal eligibility determination would have to be conducted to confirm that the site is not regulated under another VDEQ or USEPA regulatory program. For example, the determination would confirm that the case or pollution complaint associated with the UST removal in 1990 is closed. The determination would also confirm that the former landfill pre-dates any Virginia or federal regulatory programs, and therefore future cleanup of the landfill could be conducted under the VRP. Site Characterization for Voluntary Remediation Report If the Site is enrolled in the VRP, a Site Characterization Report (SCR) must be prepared and submitted to VDEQ for review and approval. The immunity granted by the CSC is limited to the releases and contaminants identified and addressed during the investigation and remediation. Therefore it is important to conduct a comprehensive investigation that identifies all potential contamination and submit the information in the Site Characterization Report and Voluntary Remediation Report. The SCR must identify and describe each area of concern (or source of contamination); the nature and extent of releases to all media, including a map of the onsite and offsite vertical and horizontal extent of contaminants above remediation levels. The 2023 investigation described in this report was designed to characterize the contents of the landfill for potential excavation and off-site disposal, and was not designed to meet the site characterization requirements of the VRP. Site characterization for the VRP requires delineating the extent of any contamination in soil and groundwater outside the former landfill, and could require delineation onto adjacent properties. Based on the data collected, the vertical and horizontal extent of lead contamination in soil and groundwater has not been determined yet, and therefore additional sampling would be required before a SCR can be submitted to VDEQ. For example, soil samples collected from the drilled shafts and borings furthest to the west (DS-6, DS-7, SB-1), north (DS-8) and northeast (DS-5 and DS-4) contained lead 28 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 21 concentrations greater than the residential criteria of 400 mg/kg. To meet VRP requirements, additional soil samples would have to be collected along the west, north and northeast property boundaries to determine the extent of contaminated soil. If contaminated soil extends to the property boundary, soil samples may have to be collected on adjacent properties. The groundwater sample collected from location GW-1 on the west side of the site contained lead, naphthalene, and 2-methylnaphthalene concentrations greater than VDEQ Tier II residential standards. To meet VRP requirements, additional groundwater sample(s) would have to be collected to determine the extent of contaminated groundwater. At this time, VDEQ does not have criteria for PFAS in soil or groundwater. Therefore delineation of PFAS compounds in soil and groundwater may not be required. In the meeting on September 20, 2023, Meade Anderson of VDEQ indicated that voluntary remediation to prevent potential exposure to PFAS compounds would be appropriate, such as an impermeable cap over soil that contains PFAS and a restriction on groundwater use. VDEQ also stated that if PFAS compounds are present in groundwater at the southern property boundary, surface water samples would need to be collected from Town Branch and analyzed for PFAS compounds. Remediation Goals and Institutional and Engineering Controls The remediation goals will be established based on the anticipated use of the property, proposed institutional and engineering controls, and appropriate risk assessment considerations. Per VDEQ’s website, the remediation goals may be based on Tier I background levels (naturally occurring), Tier II published risk-based standards, or Tier III risk assessment calculations. The risk assessment would consider exposure pathways for future land use, including the potential residential use of the Site. If remediation will not reach Tier 1 levels, then the VRP would allow for restricted closure of the site. Restricted closures, as the term suggests, involve restrictions on the use of the sites. A description of use restrictions is typically attached to the deed for the property so that future purchasers are aware of the restrictions. Restrictions may include, but not be limited to, institutional controls such as a restriction on groundwater use and engineering controls such as a cap over contaminated soil. The restrictions for the Site would have to be discussed with the private development partner and then incorporated into the risk assessment. 29 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 22 6.0 SUMMARY AND CONCLUSIONS The investigation developed the following findings:  Materials consistent with the former landfill were identified under Liberty Lot to depths of up to 20 feet below grade. The materials encountered in the drilled shafts and soil borings were relatively consistent in nature, comprised of soil and refuse material consistent with landfilling operations.  Complete removal of refuse material would generate approximately 35,000 cubic yards of combined soil and refuse material.  Soil samples from the borings and stockpile contained PAHs (petroleum HCs) concentrations that exceed residential SSLs. Arsenic, lead and cadmium exceeded residential SSLs. Lead concentrations exceed industrial SSLs.  Soil samples from the stockpile contained leachable lead concentrations that exceed hazardous waste criteria, and the stockpile must be managed as a hazardous waste and shipped to a facility permitted to accept hazardous waste.  Soil samples from the Drilled Shafts contained total lead concentrations ranging from 150 mg/kg to 4,000 mg/kg. Total lead in seven samples exceeded industrial SSL of 800 mg/kg, and total lead in five samples exceeded the residential SSL.  Soil samples from the Drilled shafts contained leachable lead at concentrations ranging from 2.3 mg/L to 84 mg/L. TCLP lead exceeded the hazardous waste threshold of 5.0 mg/L in 19 of the Drilled Shaft samples analyzed.  Groundwater samples collected at the site contained detectable concentrations of PAHs, lead, and PFAS which exceed drinking water standards or screening levels.  Nine PFAS analytes were detected in the Stockpile-3 soil sample analyzed, at a maximum concentration of 660 ng/kg (PFOS).  The source of the PFAS detected in soil and groundwater samples is not known.  Although constituents have been detected in soil and groundwater samples at concentrations greater than criteria and screening levels, no action is required if soil and refuse material remain in place. 7.0 RECOMMENDATIONS Detected concentrations of VOCs in three soil samples and one groundwater sample are below VRP risk-based screening levels for applicable exposure in an industrial setting. Considering the relatively low concentrations, no regulatory notification or corrective action is warranted. However, this investigation involved only a limited number of samples, so the detected concentrations may not be fully representative of site conditions. Additional soil sampling to assess the extent of VOCs in soil is recommended to evaluate the significance of chlorinated solvents at the site. 30 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 23 The following findings relate to potential future development of the Site: Soil An investigation was completed at the Site in June 2023. Soil samples were collected from fifteen (15) locations across the Site at depths ranging from 5 ft bgs to 32.0 feet bgs. The soil samples were evaluated for visual evidence of impacts and for total VOC content via PID screening in the field. Results of the VOC screening ranged from negative (0.0 ppmv) to 310.0 ppmv, indicating potential for pockets of contamination within the residual material. There were odors, and other visual evidence of impacts observed in the soil samples were wood fragments, glass and brick in all the borings. A total of 43 soil samples were submitted to HP Environmental, Inc. for laboratory analysis. Analytical results were compared to VRP Residential Soil Tier II, VRP Industrial Soil Tier III, and Virginia Clean Fill criteria. Multiple VOCs were detected above the laboratory reporting limits in the drilled shaft, composite drilled shaft, stockpile, and soil boring samples. Concentrations of 1,3,5- Trimethylbenzene, 1,2,4-Trimethylbenzene, and Naphthalene in drilled shaft samples were above the VRP Residential Tier II criteria but less than Industrial Tier III criteria. Multiple SVOCs were detected above the laboratory reporting limits in the drilled shaft, composite drilled shaft, stockpile, and soil boring samples. Concentrations of Naphthalene, Benzo(a)pyrene, 2-Chlorophenol, Nitrobenzene, and 2-Methylnaphthalene detected in drilled shaft and soil boring samples were above the VRP Residential Tier II criteria., but less than Industrial Tier III criteria. Multiple metals were detected above laboratory reporting limits in the drilled shaft, composite drilled shaft, stockpile, and soil boring samples. Concentrations of Arsenic, Lead, Barium, and Cadmium in the drilled shafts, soil borings and stockpiles samples above the VRP Residential Tier II criteria. Concentrations of lead in several drilled shaft, soil borings and stockpiles samples were above the VRP Industrial III criteria. Total lead concentrations in seven samples exceeded the VRP Industrial Soil Screening Level of 800 mg/kg, and exceeded the VRP Residential Soil Screening Level of 400 mg/kg in five samples. TCLP lead was detected at concentrations exceeding the hazardous waste threshold of 5.0 mg/L in 19 of the Drilled Shaft samples analyzed. The PCBs Aroclor 1260 and Aroclor 1254 were detected above the laboratory reporting limits in several drilled shaft and soil boring samples. The concentration of Aroclor-1254 in one soil boring sample was above the VRP Residential Tier II criteria but less than the industrial Tier III criteria. 31 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 24 Multiple pesticides were detected above laboratory reporting limits in the drilled shaft, composite drilled shaft, stockpile, and soil boring samples. Concentrations of 4',4'-DDD in the drilled shafts, drilled shaft composite, soil borings and stockpile samples were greater than the VRP Residential Tier II criteria but less than Industrial Tier III criteria The only herbicides detected was 2,4-DB in one drilled shaft sample. There are no VRP criteria for this compound. Groundwater Temporary groundwater monitoring wells were constructed within four soil borings to a depth of 28.0 feet bgs. Groundwater was encountered at depths ranging from 15.94 to 18.92 feet bgs. Groundwater flow direction was inferred to generally be from north to south across the Site. The following provides a summary of the groundwater sample analytical results:  VOCs: Analysis of the groundwater samples showed detectable concentrations of VOCs, including acetone, chloroform, cis-1,2-dichloroethylene, vinyl chloride, benzene, methylene chloride, and isopropyl benzene. None of the detected VOC concentrations exceed VRP screening levels.  SVOCs: Analysis of the groundwater samples detectable concentrations of various SVOCs in three of the four wells sampled. Of the detected SVOC concentrations, two exceed Tier II Residential Tap water screening levels (naphthalene and 2- methylnaphthalene).  Metals: Analysis of the groundwater samples showed detectable concentrations of metals in all four of the samples collected including lead, arsenic, barium, cadmium, chromium, and selenium. Lead concentrations exceeded Tier II Residential Tap water screening levels in two samples collected (GW-1 and GW-3).  PFAS: PFAS analytes were detected in all four of the groundwater samples collected. PFOS and PFOA detections exceed the current EPA Advisory Level for drinking water in all four samples. Although compounds were detected at concentrations greater than drinking water standards and screening levels, there are no known drinking water wells in the vicinity. Therefore no regulatory notification or corrective action is required. Site Development Considerations: If the soil and refuse material were excavated for disposal, the mixed material would not be accepted at the Loudoun County Landfill due to the concentrations of lead and other constituents present. Processing or screening the mixed material may separate out debris that could be accepted at the Loudoun County Landfill. 32 Item a. Town of Leesburg Liberty Street Lot Site Investigation Leesburg, VA October 18, 2023 25  If the soil and refuse material were excavated for disposal, most of the mixed soil and refuse would be classified as a hazardous waste because the leachable lead concentration exceeds the regulatory limit. This significantly increases the project cost. Further investigation of the soil and refuse material may be able to develop a remediation plan that distinguishes between hazardous and non-hazardous waste materials to the satisfaction of disposal facilities and VDEQ.  ‘Soil stabilization’ is often used to reduce leachable metals concentrations in contaminated soil on brownfield sites so the soil can be managed as non-hazardous waste. This process mixes Portland cement, lime or other additives into soil to reduce leaching of lead and other metals. Disposing of the soil and debris as a non-hazardous waste would also reduce potential long term liability. A treatability study would be necessary to accurately estimate the effectiveness and potential cost savings from on- site stabilization.  Excavation, screening and loading of soil and waste will generate odor, dust and noise. Soil stabilization or using screens to separate debris for disposal would generate even more dust. The Site is highly visible and there is little buffer between the Site and the residential properties to the east, north and south or the park and W&OD Trail to the south. Significant community outreach would be needed and strict monitoring and controls would be required to conduct the work without impacting adjacent properties.  The Site appears to be eligible to be enrolled in the Virginia VRP, which would provide a pathway to obtain state regulatory approval of future remediation and limit potential liability for the Town and any future owners of the Site.  Remediation of the Site under the VRP would require conducting additional soil, groundwater and surface water sampling to delineate the extent of affected soil and groundwater on the Site. If affected soil and groundwater extend to the property boundary, VRP staff would have the discretion to require soil and groundwater sampling on adjacent properties. However, investigation on adjacent properties would be affected by contamination on other properties, such as the former fuel terminal to the east.  As part of the site characterization requirements under the VRP, VDEQ would likely require analyzing surface water and sediment samples from Town Branch for PFAS compounds. The outcome of such an investigation cannot be predicted based on existing information. More generally, the regulation of the PFAS compounds (also referred to as ‘forever chemicals’) is still developing, with regular changes to criteria and standards and additional state and federal regulations likely in the future.  Remediation of the site under the VRP would not necessarily require complete removal of refuse material. If refuse material is left in place during site redevelopment, institutional and engineering controls would be required.  No action is required if soil and refuse material remain in place under the existing asphalt parking lot. 33 Item a.

WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.1 1.0 Introduction Forrest Environmental Services, Inc. (FES) performed a geophysical survey at the Liberty Street Parking Lot in Leesburg, Virginia on the 24 and 25 April 2023. The investigation consistedthth of an electromagnetic (EM) and a ground penetrating radar (GPR) surveys to locate a suspected buried metal and non-metal debris. EM data was collected along linear 5-foot traverses having stations at 10 readings per second using a MESA3 data logger connected to a Geode GPS within a sub-meter accuracy that covered approximately 200 by 350 feet. GPR data was collected at the EM anomalies that are connected to a TOPCON GPS within a sub-meter accuracy. The survey boundaries were selected by a WSP representative. Topographically, the site slopes to the northwest. The site consists of mostly of asphalt parking lot and driveways. Survey locations and physical features are shown in Figure 1. Details of the geophysical survey are described in the following sections. 96 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.2 2.0 Equipment and Procedures EM The EM survey was performed using an EM-31 induction meter to measure the apparent conductivity of the subsurface. The EM-31 consists of two horizontal coplanar loops, one acting as a transmitter and the other as a receiver. The transmitter induces electrical eddy currents in the earth, which in turn produce a secondary magnetic field. The receiver intercepts the secondary field, and the meter measures the terrain conductivity by comparing the strength of the secondary field to that of the primary field. The depth of investigation by EM is a function of the intercoil spacing and the orientation of the antenna dipoles. The EM-31 has an intercoil spacing of 12 feet, and used in the vertical dipole mode, has an effective penetration depth of approximately 18 feet. Two readings were obtained from the EM-31 at each measurement station. The EM was connected to a data logger that simultaneously recorded both the quadrature-phase component and the in-phase component. The quadrature-phase component measures the apparent terrain conductivity of the subsurface, and will detect metallic and nonmetallic objects or features with conductivities that deviate from their surroundings. The background apparent terrain conductivity value at the site was approximately 25 millimhos per meter (mmhos/m). The in-phase component measurements are proportional to an effective, average magnetic susceptibility of the surrounding earth; this mode is sensitive to large metallic objects. The readings do not indicate true magnetic susceptibility because there is an unknown additive constant and multiplying factor that would be required to convert the measured values to magnetic susceptibility. Generally, negative EM values can indicate the areal extent of large, shallow buried metal objects. The EM displays moderate-sized metal objects that are buried deep as areas of high conductivity; therefore, both high and negative readings of apparent conductivity can indicate metal. However, high conductivity materials can also be caused by conductive chemical compounds such as acids, sulfates, fly ash, and salts in the subsurface and by conductive soils 97 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.3 such as clay. Low conductivity materials such as wood and oil are generally not detectable by the EM. Ground Penetrating Radar Survey The GPR survey was performed using a Noggin Smart Cart with a shielded 250 megahertz (MHz) antenna. GPR is an EM method that detects interfaces between subsurface materials with contrasting dielectric constants. The GPR system consists of an antenna that consists of a transmitter and receiver that were connected to a computer that processes the received signal and locates the position of data collection. The transmitter radiates repetitive short-duration EM waves into the earth from the antenna as it is moved across the ground surface. These radar waves are reflected back to the receiver by interfaces between materials with different dielectric constants. The intensity of the reflected signal is a function of the dielectric constant contrast at the interface, the conductivity of the material the wave is traveling through, and the frequency of the signal. Subsurface features that cause reflections are: 1) natural geologic conditions such as changes in sediment composition, bedding and cementation horizons, voids, and water content and 2) fill materials or changes in the subsurface such as soil backfill, buried debris, USTs, pipelines, and utilities. The controlling unit receives the signal from the antenna and produces a continuous cross-section of the subsurface interface reflections. Depth of GPR signals is highly site-specific and is limited by signal attenuation or absorption of the subsurface. Signal attenuation is dependent on the electrical conductivity of subsurface materials. Signal attenuation is greatest in materials with high conductivity, such as clays or brackish groundwater, and lowest in low conductivity material, such as unsaturated sands or rock. GPR depth penetration is dependent on antenna frequency. Depth penetration increases with decreasing frequency; however, identification diminishes proportionally with smaller features. The depth penetration of this GPR survey was approximately 2.5 meters (8 feet) below surface. The GPR survey used a 250 MHz antenna that was internally shielded from above ground and adjacent anthropogenic sources. The GPR survey was performed by a project geophysicist pulling the antenna adjacent to the vents. The location of the antenna along the transects lines 98 Item a.

WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.5 3.0 Survey Results and Conclusions The objective of the geophysical survey was to determine the presence of suspected USTs and other buried metal and non-metal objects. The EM apparent terrain conductivity contour map (Figure 2) exhibited four anomalies. The EM average magnetic susceptibility contour map (Figure 3) confirms the results of the EM apparent terrain conductivity contour map. One high anomaly (Anomaly A) is centered at approximately 912000 East 14214150 feet North. GPR line was conducted at Anomaly A (Figure 1) GPR Line 1 indicated numerous anomalies. Anomaly A appears to be buried metal and non-metal dissimilar debris and fly ash. Two linear north-south anomalies are centered at approximately 912050 feet East 14214250 feet North and 912120 feet East 14214175 feet North. Anomalies B and C appear to be metal guard rails. One negative anomaly is centered at approximately 912080 feet East 14214400 feet North. Anomaly D appears to be from a surface metal 55-gallon drum. The geophysical survey indicated high within the parking lot (Figure 5). The geophysical anomalies appear to be a buried metal and non-metal debris and fly ash. 100 Item a.

Leesburg Phase 2 3310836 Project Workorder Reference Notes Samples collected by ALS personnel are done so in accordance with the procedures set forth in the ALS Field Sampling Plan (20 - Field Services Sampling Plan). Except as qualified, Clean Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 136. Except as qualified, Safe Drinking Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 141. The Chain of Custody document is included as part of this report. All Library Search analytes should be regarded as tentative identifications based on the presumptive evidence of the mass spectra. Concentrations reported are estimated values. Parameters identified as "analyze immediately" require analysis within 15 minutes of collection. Any "analyze immediately" parameters not listed under the header "Field Parameters" are preformed in the laboratory and are therefore analyzed out of hold time. Method references listed on this report beginning with the prefix “S” followed by a method number (such as S2310B-97) refer to methods from “Standard Methods for the Examination of Water and Wastewater”. For microbiological analyses, the "Prepared" value is the date/time into the incubator and the "Analyzed" value is the date/time out the incubator. An Analysis-Prep Method Cross Reference Table is included after Analytical Results & Qualifiers section in this report. Unless otherwise noted, all quantitative results for soils are reported on a dry weight basis.

Leesburg Phase 2 3310837 Project Workorder Reference Notes Samples collected by ALS personnel are done so in accordance with the procedures set forth in the ALS Field Sampling Plan (20 - Field Services Sampling Plan). Except as qualified, Clean Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 136. Except as qualified, Safe Drinking Water Act sample analyses are consistent with methodology requirements in 40 CFR Part 141. The Chain of Custody document is included as part of this report. All Library Search analytes should be regarded as tentative identifications based on the presumptive evidence of the mass spectra. Concentrations reported are estimated values. Parameters identified as "analyze immediately" require analysis within 15 minutes of collection. Any "analyze immediately" parameters not listed under the header "Field Parameters" are preformed in the laboratory and are therefore analyzed out of hold time. Method references listed on this report beginning with the prefix “S” followed by a method number (such as S2310B-97) refer to methods from “Standard Methods for the Examination of Water and Wastewater”. For microbiological analyses, the "Prepared" value is the date/time into the incubator and the "Analyzed" value is the date/time out the incubator. An Analysis-Prep Method Cross Reference Table is included after Analytical Results & Qualifiers section in this report. Unless otherwise noted, all quantitative results for soils are reported on a dry weight basis.

The VRP is a voluntary program that is designed to help property owners remediate contaminated media to protective health-based action levels. The regulations and associated guidance that have been released by the VDEQ outline the process for enrolling in the VRP, completing investigation and remediation activities, and obtaining a Certificate of Satisfactory Completion (CSC) for the contamination of interest. The immunity accorded by a CSC would apply not only to the Town as the current owner, but will run with the land and apply to future property owners. The immunity granted by issuance of the CSC is limited to the known releases addressed during the investigation and remediation, and depends on identifying the nature and extent of contamination presented in the Voluntary Remediation Report. The immunity is further conditioned upon satisfactory performance of all obligations required by VDEQ under the program and upon the veracity, accuracy, and completeness of the information submitted to VDEQ by the participant. Investigation and remediation of a property under the VRP typically includes the following steps: 1. Eligibility Determination 2. Program Enrollment 3. Prepare Voluntary Remediation Report, including Site Characterization Report and Risk Assessment, and submit to VDEQ for review and approval 4. Establish remediation goals 5. Prepare Remedial Action Plan and submit to VDEQ for review and approval 6. Conduct remediation 7. Prepare Demonstration of Satisfactory Completion and submit to VDEQ for review and approval 8. Public notice and public participation 9. VDEQ issues Certificate of Satisfactory Completion These steps are discussed in more detail in the following sections. Step 1: Eligibility Determination: The first step in the VRP process is determining if a site is eligible to enter the VRP. Contamination that is regulated under another program (for example, a regulated underground storage tank) can not be addressed under the VRP. For example, a release from a petroleum underground storage tank must be addressed under the relevant regulations, not the VRP. VDEQ is familiar with the site’s history, having conducted a field investigation in 2003. During the call with VDEQ VRP staff on 9/20/2023, Meade Anderson of VDEQ indicated that the site would be eligible for the VRP based on DEQ’s knowledge of the site history. Mr. Anderson stated that the former landfill pre-dates any regulatory programs and the cleanup of the landfill could be conducted under the VRP. Nevertheless, a formal eligibility determination must be conducted to confirm that the site is not regulated under another regulatory program. For example, the determination would confirm that the pollution 459 Item a. 2 complaint associated with the underground storage tank removal in 1990 is closed. The determination would also confirm that the former landfill pre-dates any regulatory programs, and therefore future cleanup of the landfill could be conducted under the VRP. Step 2: If the site is eligible, a $7,500 VRP enrollment fee must be submitted to VDEQ to enroll the site in the VRP and begin the VRP process. Step 3: Submit a Voluntary Remediation Report for VDEQ review and approval. The immunity granted by the CSC depends on identifying the nature and extent of contamination in the Voluntary Remediation Report. Therefore a comprehensive investigation must be conducted. The 2023 investigation focused on characterizing the contents of the landfill for potential excavation and off-site disposal. Site characterization for the VRP requires delineating the extent of contamination in soil and groundwater surrounding the former landfill, including delineation onto adjacent properties if necessary. The Voluntary Remediation Report should be submitted consistent with VRP guidance and must include the following:  Site Characterization Report (SCR). Consistent with DEQ guidelines, the SCR must provide documentation of the site conditions including the identification and description of each area of concern (or source); the nature and extent of releases to all media, including a map of the onsite and offsite vertical and horizontal extent of contaminants above remediation levels; and a discussion of the potential risk or risks posed by the release. If remedial activities have occurred prior to enrollment, this information shall be included. Based on the data collected to date, the vertical and horizontal extent of lead contamination in soil and groundwater at the Site has not been determined yet, and therefore additional sampling would be required before a SCR can be submitted to VDEQ.  Risk Assessment (RA) using the Virginia Unified Risk Assessment Model (VURAM). Consistent with DEQ guidelines, the RA should be developed using VURAM and should include an evaluation of the risks to human health and the environment posed by the release based on site characterization findings for both on and offsite properties. Step 4: Establishment of Remediation Goals. The remediation goals will be established based on the anticipated use of the property, institutional controls that might be proposed, and appropriate risk assessment considerations (reference VRP Tier I, II, and III levels). Per DEQ’s website, the remediation goals may be based on Tier I background (naturally occurring), Tier II published risk-based standards, or Tier III risk assessment calculations. If a risk assessment is performed, it should consider exposure pathways for current and future land use for levels of contaminants that will remain at the site and in surrounding areas. The remediation goals dictate whether the closure of a VRP site is “restricted” or “unrestricted.” The DEQ guidelines offer the following for consideration of restricted versus unrestricted remediation goals:  For an unrestricted closure of a VRP site, all media at a site are cleaned up to remediation levels (goals) based on either background or standards for residential exposure. No remediation techniques or controls which require ongoing management (such as institutional or engineering controls) may be employed to achieve this classification.  Restricted closures, as the term suggests, involve restrictions on the use of the sites. A description of use restrictions is typically attached to the deed for the property so that future purchasers are aware 460 Item a. 3 of them. Restrictions may include, but not be limited to, institutional controls and engineering controls. Example of institutional controls are restrictions on ground water used, or land use. Engineering controls may include caps or fences. Types of restrictions vary with site conditions and may be imposed for only a specific media; for example, groundwater. The future use of a site with restrictions may be anything from residential to industrial. The restrictions necessary to attain standards for a particular land use are described in the certification of satisfactory completion of remediation. Institutional controls could be filed under the Virginia Unified Environmental Covenant Act (UECA) which would require a survey of the property and protected area for encumberment in the property deed, or they can be filed as a simple deed attachment. The UECA approach provides protection against future land use activities as the simple deed approach can be modified without the Town’s approval in the future. In the case of the Liberty Street lot, engineering controls might include a reinforced concrete building slab and asphalt pavement capping contaminated soil. Engineering controls might also include a sub-slab depressurization system to prevent accumulation of methane or volatile compounds. Institutional controls might include regular inspections and maintenance of a cap and a deed notice. Any restrictions for the subject property will have to be negotiated with the private development partner. Step 5: Remedial Action Plan (RAP). Consistent with DEQ guidelines, the RAP should propose the specific activities, a schedule for those activities, any permits required to initiate and complete the remediation, specific design plans for implementing remediation that will achieve a remediation level, and any institutional controls that will be required to meet the remediation goals. Control or elimination of continuing onsite source or sources of releases to the environment shall be discussed. If no remedial action is justified, the RAP shall discuss the reasoning for concluding no action is necessary. Step 6: Remedial Action. The remedial action is conducted after VDEQ approves the RAP. VDEQ typically does not inspect or monitor the work. Because the contents of a former landfill can vary greatly, excavation may encounter previously undiscovered contamination or a source such as an underground storage tank. VDEQ would have to be notified of any significant changes to the RAP, and the changes would have to be documented in the remediation report. Step 7: Demonstration of Satisfactory Completion (DSC). After completing the remedial actions for the release, the owner is required to submit a DSC with the following information consistent with VRP guidelines:  A summary of the remediation implemented at the site, including a discussion of the remediation systems installed and a description of the remediation activities that occurred at the site.  a description of how onsite releases (or sources) of contamination have been eliminated or controlled, and  confirmation sampling results demonstrating that the remediation level objectives have been achieved and that the migration of contamination has been stabilized.  A description of any site restrictions including, but not limited to, land use controls that are proposed for the certificate.  A demonstration that all other criteria for completion of remediation have been satisfied. 461 Item a. 4  Certification by the participant that activities performed at the site pursuant to the VRP process have been in compliance with all applicable regulations and approved plans. Step 8: Public Participation. Once the SCR is approved by DEQ and remediation is deemed complete by DEQ, the property owner is required to have a public participation period. In WSP’s experience, this process is comprised of a newspaper announcement with notification to adjoining properties with release impacts, followed by a public comment period. Depending on the level of public interest, this may also include a public meeting. Step 9: Certificate of Satisfactory Completion Issuance. Following completion of the remedy and the public participation period the DEQ will issue a CSC for the release which will close the VRP for the Site.

The investigation results were submitted in the ‘Town of Leesburg Liberty Street Lot Site Investigation’ report dated October 9, 2023. The purpose of the investigation was to characterize the soil and solid waste in the former landfill to evaluate how it would be managed if excavated and shipped offsite during future Site redevelopment. The investigation found materials consistent with an historic landfill to depths of at least 20 feet below grade. The materials encountered were a relatively consistent mixture of soil, solid waste and debris. Most of the samples collected within the former landfill contained leachable lead concentrations that exceed hazardous waste criteria. If the soil and waste are removed, they must be managed as a hazardous waste and shipped to a facility permitted to accept hazardous waste. Soil samples also contained petroleum hydrocarbons, semi-volatile compounds, arsenic, lead and chromium concentrations that exceed regulatory criteria. Groundwater samples collected at the Site contained concentrations of lead, semivolatile compounds and Per-and polyfluoroalkyl acids (PFAS) which exceed drinking water standards or screening levels. WSP has prepared the attached preliminary cost estimate to support the Town in decision-making related to Site redevelopment, in accordance with the approved proposal. The cost estimate is divided into project phases included Plans and Permits, the Voluntary Remediation Program, Site Preparation, Remediation and Closeout and Reporting. Clendenin Consulting & Remediation Group, Bowman Consulting Group and H&H Concrete Construction, Inc., Petroleum Division assisted in estimating costs. Based on consultation with the Town, WSP has based the estimate on excavating all waste material encountered on the Site and transporting it to permitted disposal facilities. Based on the investigation findings, this estimate assumes that the mixture of soil, solid waste and debris will be excavated to a depth of 20 feet below existing ground surface. This will generate approximately 33,000 cubic yards or 52,800 tons of waste material for off-site disposal. PLANS AND PERMITS The following tasks were identified as necessary parts of the permitting process and were included in the cost estimate: Grading Plans and Grading Permit Application Demolition Permit Boundary and Topo Survey Wetlands/Streams Assessment Dry Utility Survey Pavement Markings and Signage Plan VPDES Permit and Stormwater Pollution Prevention Plan Maintenance of Traffic Plan Bond Estimate Easement Plat Entrance Phasing - Closure Plan As-built Survey Dry Utility Coordination Floodplain Analysis & Certification NVRPA Coordination for the W&OD Trail Geotechnical design of sheet pile wall 463 Item a. Page 2 The cost estimate includes the following additional tasks required due to the presence of contamination on site: Survey Town buildings for asbestos Treatability study of lead stabilization Soil and Waste Management Plan Health and Safety Plan Dewater Plan and Dewatering Discharge Permit RCRA Contingency Plan The last line item in this section of the cost estimate includes costs related to the three residences located east of the Town maintenance building (205 to 209 Wirt Street SW). Excavation of the landfill would require digging up to the back yards (western property boundary) of 205 to 209 Wirt Street SW, less than 60 feet from the buildings. This line item is included to account for additional precautions or an agreement regarding these existing residences. VDEQ VOLUNTARY REMEDIATION PROGRAM (VRP) Conducting this work under the VRP would provide additional indemnification for the Town and any development partner(s). Information on the VRP is included in the Site Investigation Report. The recent investigation of the Site focused on the horizontal and vertical limits of the historic landfill, the presence of contaminants within the historic landfill and how the waste would be managed if excavated. Under the VRP, VDEQ would require additional investigation to determine if soil and groundwater contamination extends to the property boundary. The cost estimate includes a line item for additional investigation up to the property boundary, but does not include a line item for investigation on adjacent properties. The cost estimate includes a line item to investigate if PFAS chemicals have migrated from the site to the water and sediment of Town Brach. The cost estimate does not include a line item to investigate potential sources of PFAS compounds or remediate any PFAS- impacted surface water or sediment impacts identified. WASTE DISPOSAL Based on the extent of waste material encountered, WSP estimates that complete removal of the mixed soil and solid waste will generate approximately 33,000 CY of combined soil and solid waste. Approximately 75 percent of the drilled shaft samples collected within the landfill contained leachable lead concentrations that exceed hazardous waste criteria. If the soil and waste is excavated, the data indicate that it will be classified as a hazardous waste under federal and Virginia regulations. There are a limited number of facilities that can accept hazardous waste, and the cost to manage hazardous waste is significantly higher. Based on quotes from disposal contractors and facilities, the cost estimate used the following unit rates for transportation and disposal of waste and soil: —Transportation and disposal of soil and debris classified as hazardous waste - $230 per ton. —Transportation and disposal of soil and debris classified as non-hazardous waste - $100 per ton. —Transportation and disposal of debris as non-hazardous waste at Loudoun County Landfill - $87 per ton The cost estimate assumes that shallow soils under the parking lot can be excavated first and managed as non-hazardous waste (20 % of total). The cost estimate assumes that the mix of soil and debris will be screened on site to separate debris, and the debris would be hauled to the Loudoun County Landfill (25% of total). The cost estimate assumes that the remainder of the soil would be managed as a hazardous waste (55% of total). ‘Soil stabilization’ refers to mixing Portland cement or other additives into soil to reduce leaching of lead or other metals. This method is often used to reduce the leachable metals concentrations in contaminated soil on brownfield sites so the soil can be managed as non- hazardous waste. Based on the estimated quantity of soil classified as hazardous waste in this estimate, successful stabilization of the lead has the potential to reduce the transportation and disposal costs by approximately $4.5 million, offset by the cost of the soil 464 Item a. Page 3 stabilization. Disposing of the soil and debris as a non-hazardous waste would also reduce potential long term liability. On-site stabilization also has the potential to generate more dust and odors, so additional precautions would also have to be taken to avoid impacting adjacent properties. Successful soil stabilization would require reliably achieving at least a 90 percent reduction in leachable lead to manage soil as a non- hazardous waste. Treatability studies using site soil would have to be conducted to determine if this can be achieved and the optimal reagent dose to meet the treatment goals. Therefore, a soil stabilization treatability study is included in the cost estimate, but the cost of on-site stabilization is not known at this time and has not been included. The current Site elevation is higher than the surrounding properties to the east, south and west. Excavation along these sides of the site will bring the site close to surrounding grade and the cost estimate does not include support of excavation on these sides. However, excavation of the landfill would create a steep slope on the north side of the property and therefore the cost estimate includes a line item to install sheet piling to stabilize the slope on the north side of the excavation. CONSTRUCTION DEWATERING The observed depth to groundwater on Site ranged from 15 to 20 feet below grade in the 2023 investigation. Excavation to depths of greater than 20 feet to remove all the solid waste will extend below the water table and dewatering will be required. Groundwater samples collected at the Site contained concentrations of lead, semivolatile compounds and PFAS compounds which exceed existing or proposed federal drinking water standards or action levels (lead). The cost estimate includes a line item to collect groundwater from sump pits within the excavation area, temporarily containerize the water on site, and transport it off-site to a permitted treatment and disposal facility. WSP contacted the Town Utilities Department to discuss the possible discharge of groundwater generated from construction dewatering to the sanitary sewer, which would reduce the cost. The Utilities Department stated that a discharge to the sanitary sewer system would not be authorized for the project. MINIMIZING COMMUNITY IMPACTS Residential properties are located on the east, north and south sides of the Site and Town Branch and the W&OD Trail are located on the south side. Any excavation and processing work on the Site will be highly visible and there is little buffer area from the adjacent properties. Excavation, screening, soil stabilization (if used), loading and truck traffic will generate odor, dust and noise. Strict monitoring and controls would be required on site. Hours and days of operation are likely to be restricted by the construction permit due to the residential neighboring properties. The cost estimate includes the cost of a full time environmental technician to monitor conditions on site, conduct screening and sampling as necessary, ensure contractor compliance with the various environmental plans. The cost estimate also includes equipment needed to conduct continuous dust monitoring at four locations around the perimeter of the Site. CONTINGENCY AND OTHER COSTS The cost estimate includes line items for project management (10%) and contingency (30%). This level of contingency is appropriate for a preliminary estimate since the full scope of work is not defined yet and will be partly dictated by future development plans for the Site. The cost estimate includes a line item for use of the property located across Wirt Street SW (218 Wirt Street SW). Use of this privately owned property as a truck and equipment staging area would help reduce impact on the surrounding community and reduce contractor cost. Soil and waste handling and management would still be conducted on the Liberty Street Site. This is included as a line item in the estimate, but it would be the contractor’s responsibility to negotiate and pay for use of the property. 465 Item a. Page 4 CONCLUSIONS The total estimated cost for excavation and off-site disposal of solid waste of the former landfill is approximately $16.9 million, based on the assumptions outlined in this memo. The estimated cost of transportation and disposal of the excavated soil and debris is approximately $8.9 million ($11.5 million after contingency). One option to significantly reduce the estimated cost is to reduce the depth of excavation and leave some amount of solid waste on the Site. Based on the type and concentration of contamination detected during the recent investigation, additional precautions would be required to protect human health and the environment if solid waste remains on the Site. These precautions would include a venting or mitigation system under any new building. The structural design of a new building would also have to account for the geotechnical characteristics of the mixed soil and solid waste left in place. WSP can estimate costs of the additional precautions if requested. Cc:Keith Markel, Town of Leesburg Bruce Clendenin, Clendenin Consulting & Remediation Group 466 Item a.

WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.1 1.0 Introduction Forrest Environmental Services, Inc. (FES) performed a geophysical survey at the Liberty Street Parking Lot in Leesburg, Virginia on the 24 and 25 April 2023. The investigation consistedthth of an electromagnetic (EM) and a ground penetrating radar (GPR) surveys to locate a suspected buried metal and non-metal debris. EM data was collected along linear 5-foot traverses having stations at 10 readings per second using a MESA3 data logger connected to a Geode GPS within a sub-meter accuracy that covered approximately 200 by 350 feet. GPR data was collected at the EM anomalies that are connected to a TOPCON GPS within a sub-meter accuracy. The survey boundaries were selected by a WSP representative. Topographically, the site slopes to the northwest. The site consists of mostly of asphalt parking lot and driveways. Survey locations and physical features are shown in Figure 1. Details of the geophysical survey are described in the following sections. 470 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.2 2.0 Equipment and Procedures EM The EM survey was performed using an EM-31 induction meter to measure the apparent conductivity of the subsurface. The EM-31 consists of two horizontal coplanar loops, one acting as a transmitter and the other as a receiver. The transmitter induces electrical eddy currents in the earth, which in turn produce a secondary magnetic field. The receiver intercepts the secondary field, and the meter measures the terrain conductivity by comparing the strength of the secondary field to that of the primary field. The depth of investigation by EM is a function of the intercoil spacing and the orientation of the antenna dipoles. The EM-31 has an intercoil spacing of 12 feet, and used in the vertical dipole mode, has an effective penetration depth of approximately 18 feet. Two readings were obtained from the EM-31 at each measurement station. The EM was connected to a data logger that simultaneously recorded both the quadrature-phase component and the in-phase component. The quadrature-phase component measures the apparent terrain conductivity of the subsurface, and will detect metallic and nonmetallic objects or features with conductivities that deviate from their surroundings. The background apparent terrain conductivity value at the site was approximately 25 millimhos per meter (mmhos/m). The in-phase component measurements are proportional to an effective, average magnetic susceptibility of the surrounding earth; this mode is sensitive to large metallic objects. The readings do not indicate true magnetic susceptibility because there is an unknown additive constant and multiplying factor that would be required to convert the measured values to magnetic susceptibility. Generally, negative EM values can indicate the areal extent of large, shallow buried metal objects. The EM displays moderate-sized metal objects that are buried deep as areas of high conductivity; therefore, both high and negative readings of apparent conductivity can indicate metal. However, high conductivity materials can also be caused by conductive chemical compounds such as acids, sulfates, fly ash, and salts in the subsurface and by conductive soils 471 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.3 such as clay. Low conductivity materials such as wood and oil are generally not detectable by the EM. Ground Penetrating Radar Survey The GPR survey was performed using a Noggin Smart Cart with a shielded 250 megahertz (MHz) antenna. GPR is an EM method that detects interfaces between subsurface materials with contrasting dielectric constants. The GPR system consists of an antenna that consists of a transmitter and receiver that were connected to a computer that processes the received signal and locates the position of data collection. The transmitter radiates repetitive short-duration EM waves into the earth from the antenna as it is moved across the ground surface. These radar waves are reflected back to the receiver by interfaces between materials with different dielectric constants. The intensity of the reflected signal is a function of the dielectric constant contrast at the interface, the conductivity of the material the wave is traveling through, and the frequency of the signal. Subsurface features that cause reflections are: 1) natural geologic conditions such as changes in sediment composition, bedding and cementation horizons, voids, and water content and 2) fill materials or changes in the subsurface such as soil backfill, buried debris, USTs, pipelines, and utilities. The controlling unit receives the signal from the antenna and produces a continuous cross-section of the subsurface interface reflections. Depth of GPR signals is highly site-specific and is limited by signal attenuation or absorption of the subsurface. Signal attenuation is dependent on the electrical conductivity of subsurface materials. Signal attenuation is greatest in materials with high conductivity, such as clays or brackish groundwater, and lowest in low conductivity material, such as unsaturated sands or rock. GPR depth penetration is dependent on antenna frequency. Depth penetration increases with decreasing frequency; however, identification diminishes proportionally with smaller features. The depth penetration of this GPR survey was approximately 2.5 meters (8 feet) below surface. The GPR survey used a 250 MHz antenna that was internally shielded from above ground and adjacent anthropogenic sources. The GPR survey was performed by a project geophysicist pulling the antenna adjacent to the vents. The location of the antenna along the transects lines 472 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.4 were marked electronically from a survey wheel. Recorded data were collected at 0.1-foot intervals and stored on the laptop computer. The GPR data were converted into a GPR depth model using Sensor’s and Software pulse EKKO software. The GPR data was gained, migrated, and a low frequency response filter was included to the raw data. Photo 1 - EM and GPR meter 473 Item a. WSP - Liberty Street Parking Lot - Leesburg, VA Geophysical 22266/May 2023 Forrest Environmental Services, Inc.5 3.0 Survey Results and Conclusions The objective of the geophysical survey was to determine the presence of suspected USTs and other buried metal and non-metal objects. The EM apparent terrain conductivity contour map (Figure 2) exhibited four anomalies. The EM average magnetic susceptibility contour map (Figure 3) confirms the results of the EM apparent terrain conductivity contour map. One high anomaly (Anomaly A) is centered at approximately 912000 East 14214150 feet North. GPR line was conducted at Anomaly A (Figure 1) GPR Line 1 indicated numerous anomalies. Anomaly A appears to be buried metal and non-metal dissimilar debris and fly ash. Two linear north-south anomalies are centered at approximately 912050 feet East 14214250 feet North and 912120 feet East 14214175 feet North. Anomalies B and C appear to be metal guard rails. One negative anomaly is centered at approximately 912080 feet East 14214400 feet North. Anomaly D appears to be from a surface metal 55-gallon drum. The geophysical survey indicated high within the parking lot (Figure 5). The geophysical anomalies appear to be a buried metal and non-metal debris and fly ash. 474 Item a.

Council Meeting Date: October 23, 2023 TOWN OF LEESBURG TOWN COUNCIL WORK SESSION Subject: Liberty Parking Lot - Access from South Street Staff Contact: Niraja R. Chandrapu, P.E., P.T.O.E., Transportation Engineer, Public Works and Capital Projects Renée M. LaFollette, P.E., Director, Public Works and Capital Projects Council Action Requested: Work session discussion to consider ingress and egress to the Liberty Parking Lot from South Street. Staff Recommendation: Defer action for an ingress/egress modification for the Liberty Parking Lot until a Town Council decision is made on proposed site development concepts. However, if Council decides to move forward with access improvements, staff recommends the construction of improvements for both vehicular access and pedestrian access in compliance with ADA accessibility regulations, avoidance of floodplain issues, and landfill disturbance. Commission Recommendation: Not applicable. Fiscal Impact: The preliminary estimate to convert the existing one-way exit from the Liberty Parking Lot to a two-way street movement with South Street with no pedestrian access is $100,000. The preliminary estimate to make both vehicular and ADA accessible pedestrian improvements is at least $200,000. The increased cost is attributed to the site conditions including, but not limited to, steep grades, potential utility locations, and avoidance of landfill disturbance. If Council decides to move forward with these improvements, staff will further develop the cost estimates and include in the proposed budget for the Capital Improvement Program that will be presented to Council in February 2024. If the improvements are to be funded in the current budget year, a supplemental appropriation from the Unassigned Fund Balance will be necessary. The preliminary engineering study to evaluate the site conditions was $13,700. This included a topographic survey, conceptual site layout to determine the feasibility of ingress and egress, and a minimal plan for grading, pavement marking, and signage, but did not include a review of pedestrian access. Work Plan Impact: This project is not currently part of the work plan for the Department of Public Works and Capital Projects. It will require design work, review of the design and construction document preparation, advertisement, and project management. Adding this project will impact other work already underway as part of the current Capital Improvements Program. Town Plan Impact: Legacy Leesburg Principle 4: Moving Around Town – Transportation & Mobility. This section of the Town Plan discusses the goal of establishing a safe, reliable, and efficient transportation system that promotes and enhances mobility and connectivity between neighborhoods and destinations. The proposed modification, changing the existing one-way exit- only access into a two-way access, would enhance the accessibility of Liberty Street Parking Lot for the visitors and customers of local businesses in the downtown area. 480 Item b. Liberty Parking Lot - Access from South Street October 23, 2023 Page 2 Executive Summary: At their February 28, 2023 meeting, Council requested a study to consider the feasibility of modifying the existing one-way exit-only access from the Liberty Street parking lot to South Street into a two-way access to enhance accessibility of the parking lot. Staff completed a preliminary concept study that concluded the following: 1. Site conditions do not meet important design standards related to safety, operation, and pedestrian access. 2. The grade of the access road is 15% which exceeds the Town and VDOT standards and could not be lowered due to the landfill material under the parking lot without significant remediation of the affected area. 3. Improvements will require changes to the configuration and operation of the South Street and Wirt Street intersection by incorporating an all-way stop-controlled intersection. 4. One parking space will be lost to accommodate the improvements and a stop sign on the center aisle of the parking lot will be required. Background: The Liberty Street parking lot is a Town-owned and operated facility located in the southwest portion of downtown Leesburg, south of Royal Street and west of Wirt Street (see Figure 1). A portion of the parking lot was constructed over the former municipal dump which was closed in the 1950s. The lot has 106 marked free public parking spaces and also serves as a satellite Town Public Works storage and maintenance facility. The single access to the Liberty Street parking lot is from a two-way extension of Liberty Street, located at the northwest corner of the lot immediately south of Royal Street. There is a second egress (exit) located at the southeast corner of the parking lot (South Street Exit) which exits to the intersection of South Street and Wirt Street. This existing one-way exit is approximately 100 feet long and 12 feet wide with no shoulders. Since the elevation of the parking lot is about 13.5 feet above the elevation of the Wirt Street and South Street intersection, the grade of the exit roadway is over 15%. Pedestrian access to the parking lot is limited and requires persons to walk within the parking lot travel aisles and access roadways. None of the existing pedestrian access points to the Liberty Street Lot meet ADA standards. 481 Item b. Liberty Parking Lot - Access from South Street October 23, 2023 Page 3 Figure 1: Liberty Street Parking Lot In response to a Town Council request, the Department of Public Works and Capital Projects commissioned a concept study to evaluate conversion of the existing exit roadway to the Wirt Street and South Street intersection into a two-way roadway which would provide a second access into the lot. The study evaluated how the existing exit roadway could be improved to a two-lane, two- way road to provide a safe and usable secondary entrance. The major constraints in converting the road to a two-way access are:  Landfill Disturbance: The old landfill was capped after it was closed in the 1950s. Any excavation that would disturb the landfill would need to be quantified, a comprehensive remediation plan would need to be prepared, and Virginia Department of Environmental Quality approval would be required. Accordingly, no concepts were considered that would result in significant excavation to improve the exit roadway.  Impacts on Parking Lot Operations and Number of Spaces: Two-way traffic on the South Street ramp would require changing the traffic circulation within the parking lot. These changes would result in losing one parking space which is not an impact on the operation of the parking lot.  Minimum Engineering Design Standards: The Town’s Design and Construction Standards Manual (DCSM) provides geometric standards for roadways within the Town. Standards from other entities such as VDOT and the American Association of State Highway and Transportation Officials (AASHTO) also provide standards for design of these types of roadways. The DCSM allows grades as steep as 9% for Town streets whereas VDOT allows grades as steep as 10% for private and low volume commercial entrances to public roads. Under certain conditions, VDOT allows grades as steep as 15%. However, because the road is not a public street receiving state maintenance funds, the VDOT standards are considered for guidance only. The current exit grade is close to the proposed 15% and has functioned with minimal if any issues and the proposed traffic volumes are also minimal as not all traffic comes in/out at the same time, i.e. no peak time. 482 Item b. Liberty Parking Lot - Access from South Street October 23, 2023 Page 4  Pedestrian Safety and ADA Accessibility: The existing South Street exit ramp is a one- way roadway with no pedestrian accommodation. As a result, pedestrians traveling between the parking lot and South Street walk within the roadway.  Town Branch Flood Plain Impacts: The intersection of the existing South Street exit at South Street and Wirt Street is within the FEMA floodplain for Town Branch. Any change in elevation of this intersection would need to be evaluated to determine if it would impact the flood elevations. For this reason, no concepts were considered that involved reconstruction of the intersection. The engineering study developed a concept for converting the existing South Street exit into a two- way access. The study recognized that meeting all applicable design standards was impractical without disturbing the landfill, negatively affecting the parking lot capacity and operations, and significantly increasing costs. The evaluation of reconstructing the roadway considered the anticipated low volume of traffic, its location within the downtown historic district, and the current use of the road as a one-way exit. The improvements needed to accomplish this within the constraints listed above include: 1. Widen the roadway to 20-foot pavement with 2-foot-wide gravel shoulders. This will provide two 10-foot lanes. 2. Reconfigure the existing parking lot circulation to accommodate two-way traffic on the South Street ramp. This includes adding stop signs, stop bars, and a concrete barrier to prevent unsafe turns. 3. Modify the intersection of South Street and Wirt Street, including conversion of the intersection to an all-way stop and prohibiting right turns from southbound Wirt Street into the parking lot.

Council Meeting Date: October 23, 2023 TOWN OF LEESBURG TOWN COUNCIL WORK SESSION Subject: State of the Water and Wastewater Utility Systems Staff Contact: Amy Wyks, P.E., Director of Utilities Council Action Requested: No action is required by Council at this time. Work Session discussion only. The next 5-year rate proposal for water and sewer services for Fisal Years 2025 through 2029 will be presented to Town Council on November 14, 2023. Staff Recommendation: No staff recommendation at this time. Work Session discussion only. Commission Recommendation: Not applicable. Fiscal Impact: The Town’s Water and Wastewater Utility system is a self-sustaining enterprise fund. All department expenses are funded through customer rates and fees. The FY2024 adopted includes: Budget Description FY 2024 Adopted Operating - Utilities Utilities Administration $7,830,780 Utility Maintenance $4,697,255 Water Supply $4,460,206 Water Pollution Control $7,230,672 Debt Service $5,285,309 Operating - Utilities $29,504,222 Capital Improvements Program (CIP) – Utilities $11,123,070 UTILITIES FUND GRAND TOTAL $40,627,292 A “cost of service analysis” is conducted on the Utility Fund at five-year intervals to ensure revenues are adequate to cover expenditures and to provide adequate fiscal reserves to meet bond indentures covenants and Council policy. The recommended five-year water and sewer rate plan 486 Item c. State of the Utility (Water and Wastewater Systems) October 23, 2023 Page 2 is intended to satisfy the revenue requirements for water and sewer systems capital and operating expenses. Work Plan Impact: Presenting the state of the utility system is part of the ongoing workplan for department leadership. Town Plan Impact: The daily operations of the utility system meets the goals and objectives of Strategy 2.4.2 of the Town Plan by proactively ensuring water and wastewater systems are maintained and function as designed. Executive Summary: The presentation will focus on the status of the utility systems, accomplishments, current projects, upcoming challenges, and next steps in the rate setting process. Regulatory compliance will be a key focus area for the Department in the coming years considering Environmental Protection Agency (EPA) Lead and Copper rule revisions and proposed regulations related to Perfluoroalkyl and polyfluoroalkyl substances (PFAS). In recent years, the Department of Utilities has faced unprecedented obstacles including COVID-19, significant inflation, supply chain challenges for chemicals and materials, aging infrastructure, workforce issues related to recruitment and retention and ensuring safety, reliability and resiliency of the water and sanitary sewer systems. One area of the operation that staff pays special attention to is that of water supply, especially during this summer’s ongoing drought conditions. As of the end of September 2023, the current drought status for the area remained at normal. The Interstate Commission on the Potomac River Basin (ICPRB) continues to monitor the river flow and uses other projections and estimates for their model that focuses on the entire Potomac River basin. The Cooperative Water Supply Operations on the Potomac (CO-OP) continues to be at active drought operations status which includes daily monitoring and updates. Town staff continues to monitor the situation including communication and coordination with Metropolitan Washington Council of Governments (COG) Technical Committee. Staff has been working with the Town’s rate consultant, NewGen Strategies and Solutions, to develop a recommended five-year water and sanitary sewer rate plan to ensure sufficient funding is available for operating, capital, and 3R expenses. NewGen will present the recommended utility rate plan for Fiscal Years 2025 through 2029 at the November 14, 2023 Council Meeting. Background: The 2022 Utility Department Annual Report highlights the continued growth of the Town’s utility systems including completion of projects. See Attachment #1.

A source of lead in drinking water can be household plumbing and service line materials. In 1986, lead was banned from use in pipes and solder for drinking water systems. In older homes, where lead is present in the service lines, plumbing fixtures and solder connections, it may leach into the water after the water sits for long periods of time. The Town’s drinking water is treated with a corrosion inhibitor, which is added to help prevent lead from leaching from household plumbing into drinking water. In 2021, the Environmental Protection Agency (EPA) released the much anticipated revisions to the Lead and Copper Rule. In accordance with this ruling, the EPA is requiring all water providers to identify and create an inventory of all water service lines within their distribution system. The goal of this program is to identify and replace lead service lines that may still be in existence. The EPA has confirmed an October 2024 deadline for this inventory to be completed, and since January 2022, the Town’s Department of Utilities has been diligently working towards this goal by researching historical records in order to develop a water servie line maternial inventory and map. The Department of Utilities has operated a lead sampling program since 1992, and the Town’s public water supply has always been in compliance with state and federal water quality standards. Homes built before 1988 have a higher potential for having lead in private water service lines, internal plumbing materials, and faucets. PFAS Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of more than 6,000 manmade chemicals used in the manufacture of a wide variety of industrial and household products designed to resist heat, water, oil and stains. A wide variety of products are made with PFAS, including non- stick cookware, food packaging, personal care products and water-resistant apparel. On March 14, 2023, the EPA announced its proposed national drinking water standards for 6 types of Poly-and Perfluoroalkyl Substances (PFAS) including proposed Maximum Contaminant Levels (MCLs) for Perfluorooctanoic Acid (PFOA) and Perfluorooctanesulfonic acid (PFOS). The proposed standard also includes establishing a hazard index for a combination of four other PFAS compounds. The Department of Utilities is reviewing EPA’s proposed rule along with our regional and national water utility colleagues. As we gain a clearer understanding of the implications of the proposed rule on Department of Utiliteis operations, information will be shared with our customers. The Town will take all necessary actions to meet federal and state drinking water regulations for PFAS. Exploratory testing conducted to date for several of these compounds has not indicated their presence in our drinking water. 494 Item c.

Council Meeting Date: October 23, 2023 TOWN OF LEESBURG TOWN COUNCIL WORK SESSION INFORMATION MEMORANDUM Subject: Traffic Signal at the Intersection of Battlefield Parkway NE and Fieldstone Drive NE Staff Contact: Niraja R. Chandrapu, P.E., P.T.O.E., Transportation Engineer, Public Works and Capital Projects Renée M. LaFollette, P.E., Director, Public Works and Capital Projects Council Action Requested: None at this time. Information only. Council will consider funding to signalize this intersection upon review of the proposed Capital Improvements Program to be presented by the Town Manager in February 2024. Staff Recommendation: A signal justification study has been conducted at the intersection of Battlefield Parkway NE and Fieldstone Drive NE and the results indicate that a traffic signal is warranted. Staff will advance the installation schedule of this proposed signal in the proposed Fiscal Year 2025 Capital Improvement Program for Town Council consideration. Commission Recommendation: The Residential Traffic Commission recommends the installation of a traffic signal at the subject location. Fiscal Impact: The design of the traffic signal is currently included in Fiscal Year 2029 of the Adopted 2024-2029 Capital Improvements Program. The anticipated project cost is $1,033,000. See Attachment #1. Work Plan Impact: If the project is moved forward to Fiscal Year 2025, this project will become part of the annual work plan which may require other projects to be rescheduled. Town Plan Impact: Legacy Leesburg Principle 4: Moving Around Town. This section of the new Town Plan talks about enhancing the resiliency of the transportation system by identifying issues within the Town’s network system of streets, finding effective solutions, and providing alternative options to alleviate typical traffic congestion. Executive Summary: In June 2023, an informational memorandum was prepared, outlining the plans to collect traffic count data and conduct a signal justification study at the intersection of Battlefield Parkway NE and Fieldstone Drive NE. See Attachment #2. The traffic count data was collected on Tuesday, September 12, 2023, at the subject intersection. This signal justification study considered various factors such as traffic volumes, sight distance, pedestrian and bicycle activity, operational efficiency, signal warrant analysis, and other criteria to 499 Item a. Traffic Signal at the Intersection of Battlefield Parkway NE and Fieldstone Drive NE October 23, 2023 Page 2 determine if a signal is warranted. The results of the study indicated that a traffic signal is warranted at the subject location. See Attachment #3. The recent study found the 85th percentile vehicle speed on Battlefield Parkway is 44 miles per hour. Pedestrians currently face the challenge of crossing six lanes without a refuge island. The installation of a traffic signal at the subject location is expected to significantly enhance pedestrian crossing safety. During the evaluation, three alternatives were considered: a mini roundabout, an unsignalized R- cut (Restricted Crossing U-Turn), and the traditional conventional signal. Although a single lane roundabout scored well in the evaluation, a single lane mini roundabout is not feasible at this location given the proximity to the adjacent intersections to facilitate the transition from two-lanes to single-lane configuration. An unsignalized R-Cut design also scored well in the VJuST screening. Under this design, the minor roadway left turn and through movements vehicles will turn right onto the major roadway and will make a U-turn movement at a downstream signalized intersection. The intersection of US 15 Bypass and Battlefield Parkway experiences excessive congestion during the PM peak hour and any additional U-turn traffic at this intersection will further make the congestion worse. Thus, this non- traditional design is not recommended at this location. Given the limitations of the other alternatives, the traditional conventional signal appeared to be a feasible option provided a signal is warranted. As such, a signal warrant analysis is performed in accordance with the Federal Highway Administration (FHWA) Manual on Uniform Control Devices (MUTCD) guidance for signal warrant analysis. The warrant analysis was conducted using hourly traffic volumes collected over 14 hours, along with speed data. Crash history, sight distance and intersection observations were also reviewed as part of this evaluation. The following nine warrants, as defined by the MUTCD, are evaluated in this analysis. A traffic control signal should not be installed unless one or more of the warrants are met.  Warrant 1, Eight Hour Vehicular Volume  Warrant 2, Four-Hour Vehicular Volume  Warrant 3, Peak Hour  Warrant 4, Pedestrian Volume  Warrant 5, School Crossing  Warrant 6, Coordinated Signal System  Warrant 7, Crash Experience  Warrant 8, Roadway Network  Warrant 9, Intersection Near a Grade Crossing Table 1 shows the summary of signal warrant analysis for existing conditions which indicates that a Four-Hour Vehicular warrant is met. This warrant is intended to be applied where the volume of intersecting traffic is the principal reason to consider installing a traffic control signal. During a four hour period of an average day, the data points representing the vehicles per hour on the major street and the corresponding vehicles per hour on the higher-volume minor street approach, all fall above 500 Item a. Traffic Signal at the Intersection of Battlefield Parkway NE and Fieldstone Drive NE October 23, 2023 Page 3 the applicable curve (Figure 4C-2 of the 2009 MUTCD) for the existing combination of approach lanes. See Attachment #2. Therefore, a signal is warranted and is recommended at the subject intersection. Table 1: A Summary of Signal Warrant Analysis Background: Battlefield Parkway NE and Fieldstone Drive NE is a two-way stop-controlled intersection with stop controls on Fieldstone Drive NE. Battlefield Parkway is a four-lane divided roadway with right and left turn lanes at major intersections. The roadway is classified as minor arterial by both the Town and Virginia Department of Transportation (VDOT).

VDOT Signal Justification Report Template - Version 2.0 - December 2019 Page 2 of 5 The town had originally planned to include the design of a traffic signal at the intersection of Battlefield Parkway and Fieldstone Drive in Fiscal Year 2029 as part of the Adopted 2024-2029 Capital Improvements Program (CIP). This decision was based on the anticipation that increased traffic volumes in the area would warrant a traffic signal by that time. However, due to a serious vehicular accident recently at this intersection, the town is now expediting the process. A signal justification analysis is conducted to assess the feasibility of installing a traffic signal at this intersection sooner than originally planned. If the origin of this SJR comes from another study, what were the key conclusions from that study that are related to this intersection? A signal warrant analysis was conducted as part of the Battlefield Parkway and Route 15 Bypass IAR study. For the warrant analysis, the analysis utilized the data collected in 2021 during the height of the pandemic which likely impacted the turning movement counts and study results. The analysis revealed that the intersection meets one warrant (Four-Hour Vehicular Volume Warrant), considering the operating speeds on Battlefield Parkway and without applying any right turn reductions to side street volumes.

VJuST Innovative Intersection Consideration Summary of Potentially Feasible Innovative Intersections according to VJuST results: Innovative Intersection Type Feasibility Decision and Reason Roundabout Is this Innovative Intersection type feasible? ☐ Yes ☒ No Explanation: The roundabout design scored well in the VJust screening. However, a single lane mini roundabout is not feasible at this location given the proximity to the adjacent intersections to facilitate the transition from two-lane to single-lane configuration. Unsignalized R-Cut Is this Innovative Intersection type feasible? ☐ Yes ☒ No Explanation: The unsignalized R-Cut design scored well in the VJuST screening. Under this configuration, the minor roadway left turn and through movements vehicles will turn right onto the major roadway and make a u-turn movement at the downstream signalized intersection. The intersection of US 15 Bypass and Battlefield Parkway experiences excessive congestion during the PM peak hour and any additional u-turn traffic at this intersection will further make the congestion worse. Thus, this non-traditional design is not recommended at this location. IV. Intersection Configuration and Control Recommendations and Signal Justification Intersection configuration and control recommendations: According to signal warrant analysis, a four-hour vehicular warrant is satisfied. The VJuST Intersection Screening Tool was used to consider alternatives to a traditional signal at the subject location. However, no alternatives were feasible given the proximity to the adjacent signalized intersections. Operational analyses were conducted using Synchro and SIDRA for the following conditions: • Existing Conditions (Unsignalized) • Existing Conditions (Signalized) • Existing Conditions (Roundabout) Under existing conditions, minor street approaches operate with acceptable level of service (LOS) C or better whereas the minor street left turn movements operate with LOS D during PM peak hour. Under the signalized condition, all approaches and movements operate with acceptable LOS C or better whereas under roundabout conditions, all approaches operate with LOS B or better. The analysis results are included in the Appendix C. Signal Justification: Traffic signal warrant is satisfied for Four-Hour Vehicular Volume and signalization is recommended at the subject intersection. Is an Access Management Exception or Access Management Waiver necessitated by the recommended intersection control method?: ☒ Yes ☐ No If yes, please describe the specific spacing requirement that is not met (e.g., which spacing requirement from the Road Design Manual Appendix F) and brief rationale for recommending this condition: The spacing between the subject intersection and the intersection to the west at Plaza Street is approximately 720 feet and the required spacing to meet the standards is 1,050 feet. Thus, a waiver is required with the Town of Leesburg. 510 Item a. VDOT Signal Justification Report Template - Version 2.0 - December 2019 Appendix A: Signal Warrant Analysis 511 Item a.

SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 6 | 16 Table 3: 85th Percentile Speed and ADT Existing Crashes Four Years of crash data were obtained from Virginia Department of Transportation and the Town of Leesburg at the subject intersection between the years of 2020 and present. Table 3 summarizes the crash history data. Table 4: Crash Summary (2020 to Present) Six (6) crashes were reported during the four-year time period. Out of these six crashes, three (3) of which were angle crashes that would likely be correctible by a traffic signal. Sight Distance According to Virginia Department of Transportation Road Design Manual Appendix F for intersection sight distance, the required sight distance to turn left and right onto major roadway from minor roadway for a 4-lane major roadway is 415 feet and 440 feet respectively. The field measured intersection sight distance to either turn left or right is greater than 500 feet except for the northbound left turn movement which is obstructed by the bush in the median. Trimming the bush in the median will improve the intersection sight distance for the northbound approach. MUTCD Warrants The Manual on Uniform Control Devices (MUTCD) identifies nine warrants, or requirements, to be considered for a new traffic signal installation. A traffic signal should not be installed unless a minimum of one of these warrants is met; however, the satisfaction of a traffic signal warrant or 10,131 44 Direction 85th Percentile Speed ADT Battlefield Parkway NE (Eastbound) Total 5,128 Battlefield Parkway NE (Westbound) 44 43 5,003 Crash No.Date Collision Type Injury Type 1 February 24, 2020 Rear End Property Damage Only 2 December 14, 2021 Fixed Object Property Damage Only 3 March 13, 2022 Angle Visible Injury 4 August 31, 2022 Sideswipe Property Damage Only 5 December 19, 2022 Angle Property Damage Only 6 May 18, 2023 Angle Severe Injury 517 Item a. SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 7 | 16 warrants shall not in itself require the installation of a traffic signal. Engineering judgment should also be used in the evaluation of the warrants to ensure that a traffic signal will improve the overall safety and/or operation of the intersection The MUTCD provides guidance on the treatment of right turns in the analysis, stating that “the study should consider the effects of the right-turn vehicles from the minor street approaches. Engineering judgement should be used to determine what, if any, portion of the right-turn traffic is subtracted from the minor-street traffic count when evaluating the count against the signal warrants”. The traffic volumes on Fieldstone Drive NE has heavy right turn volumes during the peak hour. Based on engineering judgement and synchro analysis, 75% of the right turn traffic is subtracted from the minor-street traffic count when evaluating the count against the signal warrants. The MUTCD allows for the volumes to be adjusted to 70% of the minimum if the posted speed limit on the major road is greater than 40 mph. The 85th percentile speed on Battlefield Parkway is 44 mph. Therefore, the 70% adjusted minimum is applicable to the evaluation of Warrant 1, Warrant 2 and Warrant 4. Warrant 1, Eight-Hour Vehicular Volume Warrant 1 is intended for application where either a large volume of intersecting traffic is the principal reason to consider installing a traffic signal (Condition A), or where the traffic volume on a major street is so heavy that traffic on a minor intersecting street suffers excessive delay or conflict in entering or crossing the major street (Condition B). The warrant may also be applied for a combination of Conditions A and B if adequate trials of other remedial measures have been implemented. No other remedial measures have been implemented; thus, a combination of Condition A and Condition B is not considered for this warrant. It is intended that Warrant 1 be treated as a single warrant. If Condition A is satisfied, then Warrant 1 is satisfied and analyses of Condition B and the combination of Conditions A and B are not needed. Similarly, if Condition B is satisfied, then Warrant 1 is satisfied and an analysis of the combination of Conditions A and B is not needed. Warrant 1 is satisfied when, for each of any eight (8) hours of an average day, the vehicles per hour on both approaches of the major street and the corresponding vehicles per hour on the higher volume minor street approach exceed the threshold provided in Table 4C-1 of the 2009 MUTCD for Condition A, Condition B, or a combination of Conditions A and B. 70% values were used from Table 4C-1 of the 2009 MUTCD as the measured 85th percentile speed on Battlefield parkway is over 40 mph. 518 Item a.

Since none of the Conditions are satisfied, Warrant 1 is not met. Warrant 2, Four-Hour Vehicular Volume This Four-Hour Vehicular Volume signal warrant is intended to be applied where the volume of intersecting traffic is the principal reason to consider installing a traffic control signal. A traffic control signal can be considered when, during a four (4) hour period of an average day, the plotted points representing the vehicles per hour on the major street (total of both approaches) and the corresponding vehicles per hour on the higher-volume minor-street approach (one direction only) all fall above the applicable curve (Figure 4C-2 of the 2009 MUTCD) for the existing combination of approach lanes. For existing volumes, four (4) data points fall above the applicable curve as shown below.

SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 10 | 16 Figure 2: Evaluation of Warrant 2 (Figure 4C-2 of the MUTCD) Warrant 3, Peak Hour This Peak Hour Vehicular Volume signal warrant is intended for use at a location where traffic conditions are such that for a minimum of one (1) hour of an average day, the minor street traffic suffers undue delay when entering or crossing the major street. This signal warrant shall be applied only in unusual cases, such as office complexes, manufacturing plants, industrial complexes, or high-occupancy vehicle facilities that attract or discharge large numbers of vehicles over a short time. None of the unusual conditions exist at the subject location. Therefore, Warrant 3 is not applicable. Warrant 4, Pedestrian Volume This Pedestrian Volume signal warrant is intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street. The signal warrant is considered if an engineering study finds that one (1) of the following criteria is met: A. For each of any 4 hours of an average day, the plotted points representing the vehicles per hour on the major street (total of both approaches) and the corresponding pedestrians per hour crossing the major street (total of all crossings) all fall above the curve (Figure 4C-6 of the 2009 MUTCD) 521 Item a.

Therefore, Condition A is not met. B. For 1 hour (any four consecutive 15-minute periods) of an average day, the plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding pedestrians per hour crossing the major street (total of all crossings) falls above the curve in Figure 4C-8 of the 2009 MUTCD. 522 Item a. SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 12 | 16 Figure 4: Pedestrian Peak Volume (Figure 4C-8 of the MUTCD) None of the data points fall above the applicable curve and the pedestrian volume is lower than the required minimum threshold for peak hour warrant. Therefore, Condition B is not met. Both Condition A and Condition B are not met at the subject location. Therefore, Warrant 4 is not met. Warrant 5, School Crossing This School Crossing signal warrant is intended for application where the fact that schoolchildren cross the major street is the principal reason to consider installing a traffic control signal. For the purposes of this warrant, the word "schoolchildren" includes elementary through high school students. This warrant is not applicable because the subject intersection is not near any school. Therefore, Warrant 5 is not applicable. Warrant 6, Coordinated Signal System Progressive movement in a coordinated signal system sometimes necessitates installing traffic control signals at intersections where they would not otherwise be needed in order to maintain proper platooning of vehicles. The adjacent signals include US 15 Bypass approximately 1,200 feet east of the study 523 Item a. SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 13 | 16 intersection, and Plaza Street approximately 720 feet west of the study intersection. There are no apparent platooning issues between the existing signals that would benefit from an additional signal at Fieldstone drive to provide a progressive operation. Therefore, Warrant 6, is not applicable. Warrant 7, Crash Experience This Crash Experience signal warrant is intended for application where the severity and frequency of crashes are the principal reasons to consider installing a traffic control signal. The need for a traffic control signal shall be considered if an engineering study finds that all of the following criteria are met: A. Adequate trial of alternatives with satisfactory observance and enforcement has failed to reduce the crash frequency; and B. Five or more reported crashes, of types susceptible to correction by a traffic control signal, have occurred within a 12-month period, each crash involving personal injury or property damage apparently exceeding the applicable requirements for a reportable crash; and C. For each of any 8 hours of an average day, the vehicles per hour (vph) given in both of the 80 percent columns of Condition A in Table 4C-1 (see Section 4C.02), or the vph in both of the 80 percent columns of Condition B in Table 4C-1 exists on the major-street and the higher-volume minor-street approach, respectively, to the intersection, or the volume of pedestrian traffic is not less than 80 percent of the requirements specified in the Pedestrian Volume warrant. These major-street and minor-street volumes shall be for the same 8 hours. On the minor street, the higher volume shall not be required to be on the same approach during each of the 8 hours. The crash data was obtained through the Virginia Department of Transportation and the Town of Leesburg. The data indicates that only one (1) crash is susceptible to correction by a traffic control signal in a 12-month period. Thus, Criterion B of the crash experience is not met. All criteria within the warrant must be met for this warrant to be satisfied. Therefore, this warrant is not met. Warrant 8, Roadway Network Installing a traffic control signal at some intersections might be justified to encourage concentration and organization of traffic flow on a roadway network. This warrant is considered for the intersection of two (2) or major routes. Since Fieldstone Dr NE is a local road and not classified as a major road, Warrant 8 is not applicable. Warrant 9, Intersection Near a Grade Crossing This Intersection Near a Grade Crossing signal warrant is intended for use at a location where none of the conditions described in the other eight traffic signal warrants are met, but the proximity to the intersection of a grade crossing on an intersection approach controlled by a 524 Item a. SIGNAL WARRANT ANALYSIS – BATTLEFIELD PARKWAY NE AT FIELDSTONE DRIVE NE P a g e 14 | 16 STOP or YIELD sign is the principal reason to consider installing a traffic control signal. Since the subject intersection is not located near a grade crossing, Warrant 9 is not applicable.

Khoury, P.E. State Traffic Engineer Richmond, VA 11/12/2019 Changes are shaded. CURRENT REVISION – SUMMARY OF REVISIONS  Removed references to the “draft” Arterial Preservation Network; the Network has now been established as described on VDOT’s Arterial Preservation web page.  Revised requirements for when roundabouts and other innovative intersections shall be considered (screened in VJuST).  Changed all “alternative intersection” references to “innovative intersections”.  Clarify additional applicability of this IIM to: o Locally-maintained signals that are a part of proposed HSIP or SMART SCALE projects. o Signals proposed as part of an IMR/IJR. o Cases where a proposed development or surrounding conditions have significantly changed since proffer approval.  Added new content: o General background information on benefits and drawbacks of traffic signals. o Standards and guidance regarding signal warrant analyses. o Prohibition of Intersection Control Beacons installation as an interim measure when the traffic signal is only justified based on anticipated growth in future years. o Clarification regarding VDOT approvals, including for cases where a proposed development or surrounding conditions have significantly changed since proffer approval. o Requirement for the SJR document to list all anticipated Access Management Exception/Waiver requests that would be triggered by the proposed intersection control method.  Reference the state’s Innovative Intersections Committee established in May 2018. 561 Item a. Page 2 of 8 November 12, 2019 BACKGROUND One of VDOT’s core priorities is to maximize multimodal mobility and minimize crash risk by focusing advancements on integrated corridors that: connect regions and major activity centers, promote the safe and efficient movement of people and goods on high volume corridors essential to the economic prosperity of the state, and address statewide goals. With greater operational and technological solutions available today to address transportation challenges, VDOT is also seeking more suitable alternatives to traditional traffic signal control that enhance corridor operations and throughput. This is further established in VTrans 2040’s Guiding Principle #4 to “Maximize capacity of the transportation network through increased use of technology and operational improvements as well as managing demand for the system before investing in major capacity expansions.” In order to advance this Guiding Principle, certain roads within Virginia that are maintained by VDOT have been designated as the Arterial Preservation Network (APN) (as described on VDOT’s Arterial Preservation web page). The Commonwealth Transportation Board (CTB) has expressed concern that the proliferation of new signals on the APN, whether due to land use development or installed via VDOT or locally- administered construction project, can collectively degrade the travel time and travel experience within and between urban centers, adversely impacting the Commonwealth’s economy. Traditional traffic signals are not a “cure-all” for operational and safety issues. Traditional signalized intersections can improve travel time and reduce delay for vehicles entering the major road from the minor road. Installation of a new traffic signal can also reduce crash risk at existing unsignalized intersections with a high Potential for Safety Improvement (PSI) ranking. However, traditional signalized intersections also have negative impacts, including:  Operational impacts: Traffic signals, particularly traditional traffic signals which have up to eight phases, interrupt traffic and increase delays for through traffic on the major road. These extra delays are cumulative on longer distance passenger travel and freight trips. Signals may create additional operational issues if they result in queues that extend to adjacent intersections and commercial entrances.  Safety impacts: Traffic signals can sometimes increase the risk and frequency of rear-end crashes. Traditional traffic signals typically have more crash risk than Innovative Intersection configurations.  Cost impacts: traffic signals represent significant installation costs – including support structures, electronics/communications infrastructure, and hardware – as well as ongoing maintenance costs. In many cases, Innovative Intersection designs have additional operational and safety benefits above those of a traditional signalized intersection. Innovative Intersections are considered an important tool for achieving the Department’s “Common Sense Engineering” philosophy, as outlined in IIM-LD-255. Innovative intersection designs do not necessarily cost significantly more than traditional intersection configurations. The construction costs for the options under consideration depend on the amount of signal equipment, turn lanes, widening, etc. required for the options under 562 Item a. Page 3 of 8 November 12, 2019 consideration. Moreover, the “true” cost of an alternative includes not just construction costs but also life-cycle maintenance and operations costs, operational impacts, and safety impacts. This Memorandum:  Establishes Signal Justification Report (SJR) policies and procedures that apply to all new traffic signals.  Establishes additional policies that apply to new traffic signals proposed on the APN.  Serves as an important component of VDOT’s eventual migration to a holistic Intersection Control Evaluation process for screening and identifying the optimum intersection configuration and control that best meets the safety and operational needs of the intersection and surrounding corridor. STANDARDS 1.1 Signal Justification Report (SJR) Basic Requirements New traffic signals shall not be installed without completion of a SJR that has been signed and sealed in accordance with the latest effective revision to IIM-TE-362, and approved by VDOT as described below. SJRs shall include signal warrant analyses in accordance with the Manual on Uniform Traffic Control Devices (MUTCD), the Virginia Supplement to the MUTCD, and this Memorandum. SJRs shall justify why a signal is not merely warranted but also justified, as per the standard statements in Section 4C.01 of the VA Supplement, “The satisfaction of a signal warrant or warrants shall not in itself require the installation of a traffic control signal … In order for a traffic signal to be justified, evidence of the need for right of way assignment beyond that which could be provided by a stop sign or other unsignalized intersection configuration1 shall be demonstrated. Examples of such a need include: excessive delay, congestion, unfavorable approach conditions, or surrounding conditions that cause driver confusion.” SJRs shall also iList all potential Access Management Waiver or Access Management Exception requests2 that would be necessitated by the recommended intersection control method, due to substandard distance to adjacent traffic signals or commercial entrances. SJR approval does not negate the requirement to seek Access Management Waiver or Exception approval. VDOT has established a standard SJR template that should be used for all SJR reports. Contact the local Traffic Engineering section for a copy of this template. SJRs are unnecessary for the following other types of traffic control devices:  Intersection Control (Flashing) Beacons. Note that if an Intersection Control (Flashing) Beacon was installed with extra signal equipment to support future conversion to full-color traffic signal operation, then the signal shall not be placed into full-color operation without an approved SJR.  Pedestrian Hybrid Beacons (PHBs). However, all proposed PHBs on VDOT-maintained roads shall be approved by the DTE, and all proposed PHBs on the APN shall be approved by the DE/DA and the STE. 1 The requirement to consider other unsignalized intersection configurations will be added to the next revision to the VA Supplement to the MUTCD. 2 VDOT is separately developing Access Management Waiver/Exception requirements for Innovative Intersections. 563 Item a. Page 4 of 8 November 12, 2019  Other unique devices covered by Chapters 4F-4N of the MUTCD (e.g. fire station squad signals, ramp meters, lane use control signals, and toll plazas signals).  Warning sign beacons, speed limit beacons, Rectangular Rapid Flashing Beacons (RRFBs), or school zone speed limit signs. 1.2 Signal Justification Report (SJR) Approval State Traffic Engineer approval and District Engineer/Administrator concurrence is required for SJR reports justifying new traffic signals on the APN. SJRs prepared external to VDOT shall be submitted first to the District Traffic Engineer for their review. If the District Traffic Engineer (DTE) and District Engineer/Administrator (DE/DA) concur with the request, then the DTE will forward the SJR to the Innovative Intersection Committee, which will aid the State Traffic Engineer in his review. The Innovative Intersection Committee (formerly the Roundabouts Committee) is further explained in IIM-TE-389/IIM-LD-257. The DE/DA is also responsible for informing the District’s CTB Representative of the proposed signal. Table 1: SJR Approval Responsibility For new traffic signals … On the APN Off the APN On VDOT-maintained road (Note 1)  DTE approval  DE/DA approval (Note 2)  STE approval (Note 2)  DTE approval On locality-maintained road (to be installed using SMART SCALE or HSIP funds) n/a - Locality-maintained roads are excluded from the APN  DTE concurrence  SJRs must be included in the final SMART SCALE or HSIP application On locality-maintained road (built with funds other than SMART SCALE or HSIP)  This IIM does not apply. However, localities must still prepare signed and sealed signal warrant studies as required by the MUTCD. DTE = District Traffic Engineer DE/DA = District Engineer/District Administrator STE = State Traffic Engineer Notes: 1) This IIM does not apply for signals that are recommended by an approved Interchange Modification Report/Interchange Justification Report (IMR/IJR) and will be constructed in conjunction with the proposed interchange improvements. However, the IMR/IJR shall still demonstrate that a signal is warranted at each proposed signalized intersection. 2) For proposed signals located on APN corridors with an Arterial Management Plan/Corridor Master Plan, SJRs may be approved at the District Traffic Engineer level (no need for State Traffic Engineer approval) if (a) the Plan recommended a traffic signal at that location, (b) the Plan was approved by VDOT and the locality, and (c) neither land use development nor traffic conditions at that location have significantly changed from the conditions anticipated in the Plan (with VDOT having the discretion to define what constitutes a “significant” change). Refer to the latest effective revision of IIM-TMPD-2 for Arterial Management Plan requirements. 564 Item a. Page 5 of 8 November 12, 2019 The latest effective revision to the SMART SCALE Technical Guide provides more information on submitting SMART SCALE applications that include new traffic signals. 2.0 Screening of Intersection Control Alternatives The VDOT Junction Screening Tool (VJuST) shall be used to screen intersection control alternatives, with the results worksheets attached to the SJR. The VJuST tool and accompanying training resources are available on VDOT’s Arterial Preservation web page. The following intersection control types shall be screened in VJuST:  Two-way stop control  Conventional signal  At least one potentially viable Innovative Intersection configuration. Other Innovative Intersection configurations deemed to be viable (as determined by engineering judgment) may be screened. o Note that roundabouts are explicitly encouraged by House Joint Resolution 594, enacted in 2003. Other Innovative Intersections can offer similar operational and safety benefits as roundabouts, and thus their use instead of traditional traffic signals would also be consistent with the aims of HJR 594. o Unsignalized Innovative Intersection configurations (e.g. roundabout or unsignalized RCUT) are usually preferable as compared to conventional or Innovative junctions that require signals. Note that the most recent edition of VJuST allows for screening of unsignalized Innovative Intersections. If the VJuST screening determines that a roundabout is feasible, then the VDOT Roundabout Tool shall be used to develop a planning-level cost comparison between the roundabout and the conventional signalized intersection alternative. An analysis tool other than VJuST may be used to screen intersection configuration options if that method is appropriately applied in accordance with TOSAM. When comparing intersection control alternatives in VJuST, all VJuST evaluation metrics shall be considered (not just v/c ratio). It is not uncommon for an innovative intersection to have slightly worse (but still acceptable) v/c ratio than the conventional signal, but significantly better safety score due to the reduced number of conflict points. For Innovative Intersection designs that potentially involve multiple signalized junctions, a single SJR report should be used to justify the proposed Innovative Intersection configuration since all the signalized “intersections” are part of the same Innovative Intersection operation. However the SJR report should separately analyze whether signals are both warranted and prudent at each junction. For example:  At Restricted Crossing U-Turn (RCUT) intersections, the U-turn crossovers may be signalized or unsignalized.  At Quadrant Roadway (QR) intersections, the end points of the quadrant roadway may be signalized or unsignalized. Warrant 8, Roadway Network, may be applicable when examining potential signalization of the various junctions that comprise the Innovative Intersection treatment. 3.0 SJRs Based on Anticipated Future Development 565 Item a. Page 6 of 8 November 12, 2019 If the justification for a proposed traffic signal is primarily driven by traffic anticipated to be generated by a future land use development, then the SJR shall include a conceptual analysis of the threshold (e.g. number of completed housing units or percent completion of commercial development) necessary to reach the volume signal warrant thresholds. Trip generation calculations shall be as per VDOT’s Traffic Impact Analysis (TIA) regulations and as approved by the District Traffic Engineer or designee. When traffic signals are proposed in conjunction with land use developments with multiple phases of development, and it is determined that the signal will not be warranted or justified until later stages of development, then VDOT may require that traffic signal construction be delayed if or until that later stage of development begins active construction. Intersection Control Beacons shall not be installed as an interim measure where a full-color- operation (red-yellow-green) traffic signal is not justified until later stages of land use development or background traffic growth, unless the beacon is justified based on existing conditions as a safety improvement due to the crash history at that intersection. 4.0 Signal Warrant Analysis Requirements General All warrant analyses shall consider, at a minimum, MUTCD warrants 1, 2, and 3 (eight-hour, four- hour, and peak-hour warrants). For intersections that are proposed primarily because of a proposed land use development, the SJR shall include the projected additional trips as documented in the associated Traffic Impact Analysis, for the purposes of analyzing MUTCD warrants 1 and 2. The ADT Estimate Warrant in the VA Supplement to the MUTCD may be used instead of MUTCD Warrants 1 and 2 if the DTE concurs that it is infeasible to project estimated opening-day volumes over 8 or more hours of the day, because the proposed signal will be on new alignment or will be part of a project that involves significant changes to existing traffic patterns. As per MUTCD section 4C.04, signals shall not be considered warranted based solely on warrant 3 (peak-hour), except in unusual cases such as manufacturing plants or HOV facilities that attract or discharge large numbers of vehicles over a short time. Right-Turn Volume Adjustment Right turn lane volumes shall be adjusted to take into account the ability of right-turning vehicles at a signal to make a right turn on red and the resulting overall improvement to the right turning movement. In the case of an approach where the final configuration will have a shared through/right turn lane, right turn volume adjustments may still be appropriate if a high proportion of the traffic using the shared lane is turning right. Some Districts may have a recommended or required methodology for right turn volume adjustment, but this IIM does not set forth any one single methodology. Potential right turn volume adjustment methods include (but are not necessarily limited to) the NCHRP Report 457 methodology, Pagones Theorem, OhioDOT Traffic Engineering Manual procedures, or PC 566 Item a. Page 7 of 8 November 12, 2019 Warrants analysis. If the District does not have a required methodology, then engineering judgment should determine which method is most appropriate for a given site. 70% Factor The MUTCD provides an Option to apply a 70% factor to various signal warrant thresholds. This factor may only be used if (a) the operating speed exceeds 40 mph or (b) the intersection “lies within the built-up area of an isolated community having a population of less than 10,000.” Note that FHWA Official Interpretation 4-346(I) clarifies that developing suburban areas do not qualify as “built up areas of an isolated community”. There is no automatic presumption that the 70% factor (and, by extension, the 56% factor) should or shall be applied; rather, the MUTCD specifies it may be applied. The 70% factor shall not be applied unless additional justification based on engineering judgment is applied to the specific location, with the engineering judgment rationale documented in the SJR. Warrant #7 (Crash warrant) MUTCD Warrant 7 (crash experience) shall be analyzed for all warrant analyses, except that warrant 7 may be omitted based on engineering judgment where the proposed signal:  is at the location of a new access point to a proposed land use development, or  will be on new alignment, or  will be within the limits of a major widening project All warrant 7 analyses shall use the most recent available three years of available crash data as per FHWA Interim Approval #19 (IA-19)3. The IA-19 procedures using one year of available crash data may be used if the designer demonstrates that it is infeasible to use three years of crash data. The 2009 MUTCD methodology shall not be used. For the purposes of IA-19, all tables listed as “rural” shall also be used for any intersection where the major speed approaches exceed 40 mph, regardless of location or functional class. EFFECTIVE DATE Existing traffic signals: This Memorandum does not apply to existing traffic signals, nor does it apply to projects involving reconstruction of existing signal equipment. Innovative Intersection designs shall be considered during the scoping phase of projects that involve partial or full widening of an existing signalized intersection in accordance with this Memorandum; however, neither District Engineer/Administrator nor State Traffic Engineer approval is required if the decision is made to maintain the intersection as a conventional signalized intersection. Where existing traffic signals * require reconstruction due to the life-cycle needs of the existing signal supports, the District Traffic Engineer or designee shall conceptually consider whether:  The existing traffic signal can reasonably be removed as per Section 4B.02 of the VA Supplement, without requiring geometric improvements beyond the scope of a typical signal reconstruction project, or  The signal phasing can reasonably be modified/simplified to improve mobility and/or reduce potential for conflict. 3 VDOT has requested and received approval from FHWA to use Interim Approval 19, on behalf of both VDOT and all Virginia localities. VDOT and localities must abide by the conditions of Interim Approval as set forth in Section 1A.10 of the MUTCD. 567 Item a. Page 8 of 8 November 12, 2019 This Memorandum does not apply to situations where existing signal supports require emergency replacement due to vehicle strike or other structural issue. Existing construction projects involving intersections not currently signalized: The previous version of this Memorandum was effective for existing projects that had not yet advanced beyond the Design Approval phase as of July 5, 2017. This version of the IIM is effective for all projects where the SJR has not yet been started as of the date of issuance for this IIM. For SJRs that were in the process of development as of this IIMs issuance date, this IIM should be applied to the extent feasible and reasonable. Land use permits for private developments: The previous version of this IIM had been be effective for all developments where the final signal warrant study had not been finalized and approved by VDOT as of July 5, 2017. This version of the IIM is effective for all developments where the first draft of the SJR has not yet been submitted to VDOT as of the date of issuance for this IIM. If the locality has approved a proffer agreement that included a traffic signal as a condition of rezoning or other land use decision, and this proposed proffer was reviewed by VDOT prior to finalizing with no objections having been submitted to the locality, then VDOT will allow a traffic signal to be built to service that development assuming the traffic signal is warranted. However, if the proposed development or the predicted traffic has significantly changed from what was reviewed by VDOT at the time of the original proffer agreement, the District will require consideration of Innovative Intersection concepts in order to best meet the safety and operational needs of anticipated opening-day traffic. The threshold for what constitutes a “significant” change shall be at the discretion of the DTE or designee. If VDOT has completed its review of a Traffic Impact Analysis (TIA) for a proposed development that included a recommendation for a new traffic signal, and did not add any qualifying conditions for the traffic signal, this Memorandum does not apply as long as the proposed development is under construction within 2 years and the traffic signal is under construction within 4 years following the TIA’s completion date. Design-Build or PPTA projects: This Memorandum shall be effective for projects in which the design criteria package has not been completed for advertisement as of January 1, 2020.

TRAFFIC CONTROL SIGNAL NEEDS STUDIES Section 4C.01 Studies and Factors for Justifying Traffic Control SignalsStandard: 01 An engineering study of traffic conditions, pedestrian characteristics, and physical characteristics of the location shall be performed to determine whether installation of a traffic control signal is justified at a particular location. 02 The investigation of the need for a traffic control signal shall include an analysis of factors related to the existing operation and safety at the study location and the potential to improve these conditions, and the applicable factors contained in the following traffic signal warrants: Warrant 1, Eight-Hour Vehicular Volume Warrant 2, Four-Hour Vehicular Volume Warrant 3, Peak Hour Warrant 4, Pedestrian Volume Warrant 5, School Crossing Warrant 6, Coordinated Signal System Warrant 7, Crash Experience Warrant 8, Roadway Network Warrant 9, Intersection Near a Grade Crossing 03 The satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal.Support: 04 Sections 8C.09 and 8C.10 contain information regarding the use of traffic control signals instead of gates and/or flashing-light signals at highway-rail grade crossings and highway-light rail transit grade crossings, respectively.Guidance: 05 A traffic control signal should not be installed unless one or more of the factors described in this Chapter are met. 06 A traffic control signal should not be installed unless an engineering study indicates that installing a traffic control signal will improve the overall safety and/or operation of the intersection. 07 A traffic control signal should not be installed if it will seriously disrupt progressive traffic flow. 08 The study should consider the effects of the right-turn vehicles from the minor-street approaches. Engineering judgment should be used to determine what, if any, portion of the right-turn traffic is subtracted from the minor-street traffic count when evaluating the count against the signal warrants listed in Paragraph 2. 09 Engineering judgment should also be used in applying various traffic signal warrants to cases where approaches consist of one lane plus one left-turn or right-turn lane. The site-specific traffic characteristics should dictate whether an approach is considered as one lane or two lanes. For example, for an approach with one lane for through and right-turning traffic plus a left-turn lane, if engineering judgment indicates that it should be considered a one-lane approach because the traffic using the left-turn lane is minor, the total traffic volume approaching the intersection should be applied against the signal warrants as a one-lane approach. The approach should be considered two lanes if approximately half of the traffic on the approach turns left and the left-turn lane is of sufficient length to accommodate all left-turn vehicles. 10 Similar engineering judgment and rationale should be applied to a street approach with one through/left-turn lane plus a right-turn lane. In this case, the degree of conflict of minor-street right-turn traffic with traffic on the major street should be considered. Thus, right-turn traffic should not be included in the minor-street volume if the movement enters the major street with minimal conflict. The approach should be evaluated as a one-lane approach with only the traffic volume in the through/left-turn lane considered. 11 At a location that is under development or construction and where it is not possible to obtain a traffic count that would represent future traffic conditions, hourly volumes should be estimated as part of an engineering study for comparison with traffic signal warrants. Except for locations where the engineering study uses the satisfaction of Warrant 8 to justify a signal, a traffic control signal installed under projected conditions should have an engineering study done within 1 year of putting the signal into stop-and-go operation to determine if the signal is justified. If not justified, the signal should be taken out of stop-and-go operation or removed. 12 For signal warrant analysis, a location with a wide median, even if the median width is greater than 30 feet, should be considered as one intersection. Sect. 4C.01 December 2009 569 Item a. 2009 Edition Page 437 Option: 13 At an intersection with a high volume of left-turn traffic from the major street, the signal warrant analysis may be performed in a manner that considers the higher of the major-street left-turn volumes as the “minor-street” volume and the corresponding single direction of opposing traffic on the major street as the “major-street” volume. 14 For signal warrants requiring conditions to be present for a certain number of hours in order to be satisfied, any four sequential 15-minute periods may be considered as 1 hour if the separate 1-hour periods used in the warrant analysis do not overlap each other and both the major-street volume and the minor-street volume are for the same specific one-hour periods. 15 For signal warrant analysis, bicyclists may be counted as either vehicles or pedestrians.Support: 16 When performing a signal warrant analysis, bicyclists riding in the street with other vehicular traffic are usually counted as vehicles and bicyclists who are clearly using pedestrian facilities are usually counted as pedestrians.Option: 17 Engineering study data may include the following: A. The number of vehicles entering the intersection in each hour from each approach during 12 hours of an average day. It is desirable that the hours selected contain the greatest percentage of the 24-hour traffic volume. B. Vehicular volumes for each traffic movement from each approach, classified by vehicle type (heavy trucks, passenger cars and light trucks, public-transit vehicles, and, in some locations, bicycles), during each 15-minute period of the 2 hours in the morning and 2 hours in the afternoon during which total traffic entering the intersection is greatest. C. Pedestrian volume counts on each crosswalk during the same periods as the vehicular counts in Item B and during hours of highest pedestrian volume. Where young, elderly, and/or persons with physical or visual disabilities need special consideration, the pedestrians and their crossing times may be classified by general observation. D. Information about nearby facilities and activity centers that serve the young, elderly, and/or persons with disabilities, including requests from persons with disabilities for accessible crossing improvements at the location under study. These persons might not be adequately reflected in the pedestrian volume count if the absence of a signal restrains their mobility. E. The posted or statutory speed limit or the 85th-percentile speed on the uncontrolled approaches to the location. F. A condition diagram showing details of the physical layout, including such features as intersection geometrics, channelization, grades, sight-distance restrictions, transit stops and routes, parking conditions, pavement markings, roadway lighting, driveways, nearby railroad crossings, distance to nearest traffic control signals, utility poles and fixtures, and adjacent land use. G. A collision diagram showing crash experience by type, location, direction of movement, severity, weather, time of day, date, and day of week for at least 1 year. 18 The following data, which are desirable for a more precise understanding of the operation of the intersection, may be obtained during the periods described in Item B of Paragraph 17: A. Vehicle-hours of stopped time delay determined separately for each approach. B. The number and distribution of acceptable gaps in vehicular traffic on the major street for entrance from the minor street. C. The posted or statutory speed limit or the 85th-percentile speed on controlled approaches at a point near to the intersection but unaffected by the control. D. Pedestrian delay time for at least two 30-minute peak pedestrian delay periods of an average weekday or like periods of a Saturday or Sunday. E. Queue length on stop-controlled approaches. Section 4C.02 Warrant 1, Eight-Hour Vehicular VolumeSupport: 01 The Minimum Vehicular Volume, Condition A, is intended for application at locations where a large volume of intersecting traffic is the principal reason to consider installing a traffic control signal. 02 The Interruption of Continuous Traffic, Condition B, is intended for application at locations where Condition A is not satisfied and where the traffic volume on a major street is so heavy that traffic on a minor intersecting street suffers excessive delay or conflict in entering or crossing the major street. 03 It is intended that Warrant 1 be treated as a single warrant. If Condition A is satisfied, then Warrant 1 is satisfied and analyses of Condition B and the combination of Conditions A and B are not needed. Similarly, if Condition B is satisfied, then Warrant 1 is satisfied and an analysis of the combination of Conditions A and B is not needed. December 2009 Sect. 4C.01 to 4C.02570 Item a. Page 438 2009 Edition Standard: 04 The need for a traffic control signal shall be considered if an engineering study finds that one of the following conditions exist for each of any 8 hours of an average day: A. The vehicles per hour given in both of the 100 percent columns of Condition A in Table 4C-1 exist on the major-street and the higher-volume minor-street approaches, respectively, to the intersection; or B. The vehicles per hour given in both of the 100 percent columns of Condition B in Table 4C-1 exist on the major-street and the higher-volume minor-street approaches, respectively, to the intersection.In applying each condition the major-street and minor-street volumes shall be for the same 8 hours. On the minor street, the higher volume shall not be required to be on the same approach during each of these 8 hours.Option: 05 If the posted or statutory speed limit or the 85th-percentile speed on the major street exceeds 40 mph, or if the intersection lies within the built-up area of an isolated community having a population of less than 10,000, the traffic volumes in the 70 percent columns in Table 4C-1 may be used in place of the 100 percent columns.Guidance: 06 The combination of Conditions A and B is intended for application at locations where Condition A is not satisfied and Condition B is not satisfied and should be applied only after an adequate trial of other alternatives that could cause less delay and inconvenience to traffic has failed to solve the traffic problems.Standard: 07 The need for a traffic control signal shall be considered if an engineering study finds that both of the following conditions exist for each of any 8 hours of an average day: A. The vehicles per hour given in both of the 80 percent columns of Condition A in Table 4C-1 exist on the major-street and the higher-volume minor-street approaches, respectively, to the intersection; and B. The vehicles per hour given in both of the 80 percent columns of Condition B in Table 4C-1 exist on the major-street and the higher-volume minor-street approaches, respectively, to the intersection.These major-street and minor-street volumes shall be for the same 8 hours for each condition; however, the 8 hours satisfied in Condition A shall not be required to be the same 8 hours satisfied in Condition B. On the minor street, the higher volume shall not be required to be on the same approach during each of the 8 hours. Table 4C-1.

Section 4C.03 Warrant 2, Four-Hour Vehicular VolumeSupport: 01 The Four-Hour Vehicular Volume signal warrant conditions are intended to be applied where the volume of intersecting traffic is the principal reason to consider installing a traffic control signal.Standard: 02 The need for a traffic control signal shall be considered if an engineering study finds that, for each of any 4 hours of an average day, the plotted points representing the vehicles per hour on the major street (total of both approaches) and the corresponding vehicles per hour on the higher-volume minor-street approach (one direction only) all fall above the applicable curve in Figure 4C-1 for the existing combination of approach lanes. On the minor street, the higher volume shall not be required to be on the same approach during each of these 4 hours.Option: 03 If the posted or statutory speed limit or the 85th-percentile speed on the major street exceeds 40 mph, or if the intersection lies within the built-up area of an isolated community having a population of less than 10,000, Figure 4C-2 may be used in place of Figure 4C-1. Section 4C.04 Warrant 3, Peak HourSupport: 01 The Peak Hour signal warrant is intended for use at a location where traffic conditions are such that for a minimum of 1 hour of an average day, the minor-street traffic suffers undue delay when entering or crossing the major street.Standard: 02 This signal warrant shall be applied only in unusual cases, such as office complexes, manufacturing plants, industrial complexes, or high-occupancy vehicle facilities that attract or discharge large numbers of vehicles over a short time. 03 The need for a traffic control signal shall be considered if an engineering study finds that the criteria in either of the following two categories are met: A. If all three of the following conditions exist for the same 1 hour (any four consecutive 15-minute periods) of an average day: 1. The total stopped time delay experienced by the traffic on one minor-street approach (one direction only) controlled by a STOP sign equals or exceeds: 4 vehicle-hours for a one-lane approach or 5 vehicle-hours for a two-lane approach; and 2. The volume on the same minor-street approach (one direction only) equals or exceeds 100 vehicles per hour for one moving lane of traffic or 150 vehicles per hour for two moving lanes; and 3. The total entering volume serviced during the hour equals or exceeds 650 vehicles per hour for intersections with three approaches or 800 vehicles per hour for intersections with four or more approaches. B. The plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding vehicles per hour on the higher-volume minor-street approach (one direction only) for 1 hour (any four consecutive 15-minute periods) of an average day falls above the applicable curve in Figure 4C-3 for the existing combination of approach lanes.Option: 04 If the posted or statutory speed limit or the 85th-percentile speed on the major street exceeds 40 mph, or if the intersection lies within the built-up area of an isolated community having a population of less than 10,000, Figure 4C-4 may be used in place of Figure 4C-3 to evaluate the criteria in the second category of the Standard. 05 If this warrant is the only warrant met and a traffic control signal is justified by an engineering study, the traffic control signal may be operated in the flashing mode during the hours that the volume criteria of this warrant are not met.Guidance: 06 If this warrant is the only warrant met and a traffic control signal is justified by an engineering study, the traffic control signal should be traffic-actuated.

Page 442 2009 Edition Section 4C.05 Warrant 4, Pedestrian VolumeSupport: 01 The Pedestrian Volume signal warrant is intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street.Standard: 02 The need for a traffic control signal at an intersection or midblock crossing shall be considered if an engineering study finds that one of the following criteria is met: A. For each of any 4 hours of an average day, the plotted points representing the vehicles per hour on the major street (total of both approaches) and the corresponding pedestrians per hour crossing the major street (total of all crossings) all fall above the curve in Figure 4C-5; or B. For 1 hour (any four consecutive 15-minute periods) of an average day, the plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding pedestrians per hour crossing the major street (total of all crossings) falls above the curve in Figure 4C-7.Option: 03 If the posted or statutory speed limit or the 85th-percentile speed on the major street exceeds 35 mph, or if the intersection lies within the built-up area of an isolated community having a population of less than 10,000, Figure 4C-6 may be used in place of Figure 4C-5 to evaluate Criterion A in Paragraph 2, and Figure 4C-8 may be used in place of Figure 4C-7 to evaluate Criterion B in Paragraph 2.Standard: 04 The Pedestrian Volume signal warrant shall not be applied at locations where the distance to the nearest traffic control signal or STOP sign controlling the street that pedestrians desire to cross is less than 300 feet, unless the proposed traffic control signal will not restrict the progressive movement of traffic. 05 If this warrant is met and a traffic control signal is justified by an engineering study, the traffic control signal shall be equipped with pedestrian signal heads complying with the provisions set forth in Chapter 4E.Guidance: 06 If this warrant is met and a traffic control signal is justified by an engineering study, then: A. If it is installed at an intersection or major driveway location, the traffic control signal should also control the minor-street or driveway traffic, should be traffic-actuated, and should include pedestrian detection. B. If it is installed at a non-intersection crossing, the traffic control signal should be installed at least 100 feet from side streets or driveways that are controlled by STOP or YIELD signs, and should be pedestrian-actuated. If the traffic control signal is installed at a non-intersection crossing, at least one of the signal faces should be over the traveled way for each approach, parking and other sight obstructions should be prohibited for at least 100 feet in advance of and at least 20 feet beyond the crosswalk or site accommodations should be made through curb extensions or other techniques to provide adequate sight distance, and the installation should include suitable standard signs and pavement markings. C. Furthermore, if it is installed within a signal system, the traffic control signal should be coordinated.Option: 07 The criterion for the pedestrian volume crossing the major street may be reduced as much as 50 percent if the 15th-percentile crossing speed of pedestrians is less than 3.5 feet per second. 08 A traffic control signal may not be needed at the study location if adjacent coordinated traffic control signals consistently provide gaps of adequate length for pedestrians to cross the street. Section 4C.06 Warrant 5, School CrossingSupport: 01 The School Crossing signal warrant is intended for application where the fact that schoolchildren cross the major street is the principal reason to consider installing a traffic control signal. For the purposes of this warrant, the word “schoolchildren” includes elementary through high school students.Standard: 02 The need for a traffic control signal shall be considered when an engineering study of the frequency and adequacy of gaps in the vehicular traffic stream as related to the number and size of groups of schoolchildren at an established school crossing across the major street shows that the number of adequate gaps in the traffic stream during the period when the schoolchildren are using the crossing is less than the number of minutes in the same period (see Section 7A.03) and there are a minimum of 20 schoolchildren during the highest crossing hour.

If it is installed at an intersection or major driveway location, the traffic control signal should also control the minor-street or driveway traffic, should be traffic-actuated, and should include pedestrian detection. B. If it is installed at a non-intersection crossing, the traffic control signal should be installed at least 100 feet from side streets or driveways that are controlled by STOP or YIELD signs, and should be pedestrian-actuated. If the traffic control signal is installed at a non-intersection crossing, at least one of the signal faces should be over the traveled way for each approach, parking and other sight obstructions should be prohibited for at least 100 feet in advance of and at least 20 feet beyond the crosswalk or site accommodations should be made through curb extensions or other techniques to provide adequate sight distance, and the installation should include suitable standard signs and pavement markings. C. Furthermore, if it is installed within a signal system, the traffic control signal should be coordinated. Section 4C.07 Warrant 6, Coordinated Signal SystemSupport: 01 Progressive movement in a coordinated signal system sometimes necessitates installing traffic control signals at intersections where they would not otherwise be needed in order to maintain proper platooning of vehicles.Standard: 02 The need for a traffic control signal shall be considered if an engineering study finds that one of the following criteria is met: A. On a one-way street or a street that has traffic predominantly in one direction, the adjacent traffic control signals are so far apart that they do not provide the necessary degree of vehicular platooning. B. On a two-way street, adjacent traffic control signals do not provide the necessary degree of platooning and the proposed and adjacent traffic control signals will collectively provide a progressive operation.Guidance: 03 The Coordinated Signal System signal warrant should not be applied where the resultant spacing of traffic control signals would be less than 1,000 feet. Section 4C.08 Warrant 7, Crash ExperienceSupport: 01 The Crash Experience signal warrant conditions are intended for application where the severity and frequency of crashes are the principal reasons to consider installing a traffic control signal.Standard: 02 The need for a traffic control signal shall be considered if an engineering study finds that all of the following criteria are met: A. Adequate trial of alternatives with satisfactory observance and enforcement has failed to reduce the crash frequency; and B. Five or more reported crashes, of types susceptible to correction by a traffic control signal, have occurred within a 12-month period, each crash involving personal injury or property damage apparently exceeding the applicable requirements for a reportable crash; and C. For each of any 8 hours of an average day, the vehicles per hour (vph) given in both of the 80 percent columns of Condition A in Table 4C-1 (see Section 4C.02), or the vph in both of the 80 percent columns of Condition B in Table 4C-1 exists on the major-street and the higher-volume minor-street approach, respectively, to the intersection, or the volume of pedestrian traffic is not less than 80 percent of the requirements specified in the Pedestrian Volume warrant. These major-street and minor-street volumes shall be for the same 8 hours. On the minor street, the higher volume shall not be required to be on the same approach during each of the 8 hours. December 2009 Sect. 4C.06 to 4C.08578 Item a. Page 446 2009 Edition Option: 03 If the posted or statutory speed limit or the 85th-percentile speed on the major street exceeds 40 mph, or if the intersection lies within the built-up area of an isolated community having a population of less than 10,000, the traffic volumes in the 56 percent columns in Table 4C-1 may be used in place of the 80 percent columns. Section 4C.09 Warrant 8, Roadway NetworkSupport: 01 Installing a traffic control signal at some intersections might be justified to encourage concentration and organization of traffic flow on a roadway network.Standard: 02 The need for a traffic control signal shall be considered if an engineering study finds that the common intersection of two or more major routes meets one or both of the following criteria: A. The intersection has a total existing, or immediately projected, entering volume of at least 1,000 vehicles per hour during the peak hour of a typical weekday and has 5-year projected traffic volumes, based on an engineering study, that meet one or more of Warrants 1, 2, and 3 during an average weekday; or B. The intersection has a total existing or immediately projected entering volume of at least 1,000 vehicles per hour for each of any 5 hours of a non-normal business day (Saturday or Sunday). 03 A major route as used in this signal warrant shall have at least one of the following characteristics: A. It is part of the street or highway system that serves as the principal roadway network for through traffic flow. B. It includes rural or suburban highways outside, entering, or traversing a city. C. It appears as a major route on an official plan, such as a major street plan in an urban area traffic and transportation study. Section 4C.10 Warrant 9, Intersection Near a Grade CrossingSupport: 01 The Intersection Near a Grade Crossing signal warrant is intended for use at a location where none of the conditions described in the other eight traffic signal warrants are met, but the proximity to the intersection of a grade crossing on an intersection approach controlled by a STOP or YIELD sign is the principal reason to consider installing a traffic control signal.Guidance: 02 This signal warrant should be applied only after adequate consideration has been given to other alternatives or after a trial of an alternative has failed to alleviate the safety concerns associated with the grade crossing. Among the alternatives that should be considered or tried are: A. Providing additional pavement that would enable vehicles to clear the track or that would provide space for an evasive maneuver, or B. Reassigning the stop controls at the intersection to make the approach across the track a non-stopping approach.Standard: 03 The need for a traffic control signal shall be considered if an engineering study finds that both of the following criteria are met: A. A grade crossing exists on an approach controlled by a STOP or YIELD sign and the center of the track nearest to the intersection is within 140 feet of the stop line or yield line on the approach; and B. During the highest traffic volume hour during which rail traffic uses the crossing, the plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding vehicles per hour on the minor-street approach that crosses the track (one direction only, approaching the intersection) falls above the applicable curve in Figure 4C-9 or 4C-10 for the existing combination of approach lanes over the track and the distance D, which is the clear storage distance as defined in Section 1A.13.Guidance: 04 The following considerations apply when plotting the traffic volume data on Figure 4C-9 or 4C-10: A. Figure 4C-9 should be used if there is only one lane approaching the intersection at the track crossing location and Figure 4C-10 should be used if there are two or more lanes approaching the intersection at the track crossing location.

For example, if the actual distance D is 95 feet, the plotted point should be compared to the curve for D = 90 feet. C. If the rail traffic arrival times are unknown, the highest traffic volume hour of the day should be used.Option: 05 The minor-street approach volume may be multiplied by up to three adjustment factors as provided in Paragraphs 6 through 8. 06 Because the curves are based on an average of four occurrences of rail traffic per day, the vehicles per hour on the minor-street approach may be multiplied by the adjustment factor shown in Table 4C-2 for the appropriate number of occurrences of rail traffic per day. 07 Because the curves are based on typical vehicle occupancy, if at least 2% of the vehicles crossing the track are buses carrying at least 20 people, the vehicles per hour on the minor-street approach may be multiplied by the adjustment factor shown in Table 4C-3 for the appropriate percentage of high-occupancy buses. 08 Because the curves are based on tractor-trailer trucks comprising 10% of the vehicles crossing the track, the vehicles per hour on the minor-street approach may be multiplied by the adjustment factor shown in Table 4C-4 for the appropriate distance and percentage of tractor-trailer trucks.Standard: 09 If this warrant is met and a traffic control signal at the intersection is justified by an engineering study, then: A. The traffic control signal shall have actuation on the minor street; B. Preemption control shall be provided in accordance with Sections 4D.27, 8C.09, and 8C.10; and C. The grade crossing shall have flashing-light signals (see Chapter 8C).Guidance: 10 If this warrant is met and a traffic control signal at the intersection is justified by an engineering study, the grade crossing should have automatic gates (see Chapter 8C).

October 2, 2023 Dear Visit Loudoun Board, I’m very pleased to share the attached release which just went out, which I’ve also copied below. If you would like to see the entire data set, please click here. LEESBURG (October 2, 2023)- Loudoun’s tourism revenue topped $4 billion in 2022, with Washington Dulles International Airport being a major contributor to the local economy, according to the latest data released by Virginia Tourism. Overall visitor spending in Loudoun was up 32 percent from 2021, with $2.3 billion of that coming from transportation, according to the data, which is collected by Tourism Economics. Loudoun is the largest tourism revenue generator in the Commonwealth, contributing 13.2 percent to the overall visitor spending in the state. “While Dulles Airport is clearly an economic engine for the region, we continue to see an uptick across the board with a 29 percent growth in spending in our lodging, restaurants and craft beverage segments while our recreation and retail segments saw a 28.8 percent and 15.7 percent increase over 2021 respectively,” Visit Loudoun President & CEO Beth Erickson said. “The growth at Dulles Airport, along with Metro's extension into the county, has provided greater opportunities for Loudoun as a destination and benefits Loudoun's robust visitor economy as a whole." According to the economic impact report, in 2022 tourism supported 17,134 jobs, up 26.6 percent, which generated $988 million in salaries and wages in Loudoun. It generated $136 million in local taxes as well as $72.6 million in state taxes, increases of 24.8 percent and 31.9 percent over 2021 respectively. “Dulles International Airport is proud to welcome passengers from across the nation and around the world who support the businesses and attractions of Loudoun County,” said Chryssa Westerlund, executive vice president and chief revenue officer of the Metropolitan Washington Airports Authority. “Dulles has added more international flights since 2019 than any other airport in the U.S., making it America’s fastest growing international gateway. Key drivers for the airport’s growth include excellent partnerships with the region’s tourism, economic development and transportation organizations.” Across the state, Virginia’s tourism revenue reached $30.3 billion in 2022. This spending supported 210,721 jobs, an increase of more than 25,000 jobs relative to 2021, but still down about 30,000 jobs relative to 2019.The leading tourism sectors in Virginia are recreation and food & beverage, which have exceeded 2019 levels by 10 percent. Transportation, specifically air travel, has had a slower rebound but was the fastest growing tourism sector in 2022, aiding the Commonwealth’s regions that are more dependent on-air travel. With the additional marketing dollars that came through the American Rescue Plan Act (ARPA) funds, Virginia and its localities continued to see growth in visitor spending. Thank you for your continued support of Loudoun’s tourism & hospitality industry. Beth Erickson, CTA, CDME President & CEO 587 Item b.
