Could have other sections further away if required by contraction and expansion cones. Those additional survey cross sections could come from the previous time this report was completed for the previous alignment. MCB AFour (4) additional surveyed cross sections were added to the existing and proposed models for a total of seven (7) surveyed sections, in order to conform with IDOT and HEC-RAS stream survey and Bridge Hydraulics modeling protocol. A summary of model cross sections was added to Appendix F-2.CLOSED2 Cover Page Batistas Make sure next submittal is not in a three ring binder.

If the 2-year is in the model, list it here also.MCB AStated the 10, 50, 100 and 500 year flows at our location. CLOSED7Section 9.0, paragraph 2BatistasCall the FIS model Effective or Base model. Don´t call it existing so not to confuse the readers. Explain if the FIS model was truncated for this report and if so explain at what cross section the truncated model starts and finish, what is the total length and how many FIS cross sections it contains. MCB AChanged name of FIS model to "base model" throughout report. Existing revised changed to "existing model" throughout the report. This information is covered in the following section.CLOSED8Section 9.0, paragraph 2BatistasAre you sure no Natural model is required. Because FIS cross section DL runs at an angle where the proposed bridge is going and it must be adjusted in existing and proposed run. Does this have any impact. MCB BNo natural model is required, as the existing and base model are in good agreement, and new sections do not materially impact results. Language added to clarify.

Murphy, and Tilly, Inc. to design a segment of 143rd Street from Illinois Route 59 to Illinois Route 126 in Will County, Illinois. Appendix C-1 Aerial Location Map and C-2 USGS Quadrangle Map provide a graphic depiction of the location of the project. No roadway currently exists in this corridor, and the proposed roadway will consist of 4 lanes of traffic. The project will entail one new river crossing of the DuPage River and a culvert extension at the West Norman Drain, impacting both floodplains. This hydraulic report focuses on the DuPage River and a separate hydraulic report will focus on the West Norman Drain. The proposed bridge over the DuPage River will be structure number 099-6006. This hydraulic report is an update to the hydraulic report from October 2008 with Illinois Department of Transportation (IDOT) approval in February of 2009. The update includes the new alignment of proposed 143rd Street (shifted north from the previous alignment) and modeling using the latest (2019) information from the Federal Emergency Management Agency (FEMA). 2.0 Description of Existing Structure and Floodplain The project corridor is River flows from north to south at this location. In the vicinity of the bridge, the DuPage River has a wide floodway, and the floodplain is approximately 1,000 feet wide. The channel has a significant located upstream of the confluence of the DuPage River and the West Norman Drain. There is no structure at this current location. The roadway is proposed to run in an east-west direction parallel to the West Norman Drain on its north side and will have a small impact on its floodplain. In this vicinity, the West Norman Drain flows from west to east. In addition, the roadway is proposed to span the DuPage River via a bridge. The DuPage number of meanders, and there is a considerable amount of erosion to the channel banks. There does not appear to be a great deal of debris collection through the project corridor. The floodplain is primarily brush and farm fields, with some residential properties along the east portion of the West Norman floodplain. Wetlands are located on the western and eastern banks of the DuPage River at the project location in addition to the confluence of the DuPage River and West Norman Drain south of the roadway. 3.0 Field Observations Erosion/migration of the DuPage River along the west bank and debris identifying highwater locations from the May 3, 2019 flood event were observed. See Appendix D-2 Photographs. 4.0 Historical Observations and Records The land adjacent to the DuPage River is floodplain and prone to flooding. There is no data, such as district operations reports, available from the largest rain event occurring in 1996. Pictures and data are available from the September 15, 2008 and May 3, 2019 events. Flooding pictures from the May 3, 2019 event around the area of the project are included in Appendix D- 2 Photographs. There is debris identifying high water. No homes are known to have flooded directly. Flooding occurred on September 15, 2008 due to three consecutive days of rain across the Midwest. Weller Drive, west of Naperville Road, was partially inundated, but the no homes are known to have 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 5 of 12 flooded. The flooding of Weller Drive is shown in Appendix D-2 Photographs. Approximately 7 inches of rain fell as measured by the O’Hare rain gauge between September 13th and September 15th, which resulted in flooding throughout the area. As seen in Appendix M-1 Survey Notes, the measured water surface elevation east of the DuPage River south of the location of the proposed bridge was 605.3 based on the NGVD 1929 datum (605.1 based on the NAVD 1988 datum). The measured water surface elevation at the eastern face of the IL Route 59 Bridge over the West Norman Drain was approximately 605.5 (FEMA Datum – NGVD 1929). Additionally, residential homes located west of Plainfield/Naperville Road, shown in Appendix C-1 Aerial Location Map, were affected by the flooding which resulted in roadway closure. Flooding photos can be found in Appendix D-2 Photographs. Data is available for a large storm event that occurred in October 1954 as shown in the hydrologic atlas. As seen in Appendix D-3 Historical Flooding, the DuPage River water surface elevation at the proposed location of the bridge during this flood was 606.76 feet. 5.0 Other Studies & Affected Agencies The Flood Insurance Study (FIS) for Will County, Illinois is effective February 15, 2019. Models were requested and received from FEMA. The modeling was not updated for the 2019 FIS study and is the same as the FIS study effective September of 1995. The difference between the 2019 flood profiles and the previous 2015 FIS profiles is the datum adjustment between the current FIS datum, NAVD 1988 and the previous FIS datum, NGVD 29. Excerpts from the 2019 FIS study is available in Appendix D-1 FIS/FIRM Data. There is also an Army Corps of Engineers (USACE) DuPage River Feasibility Study that was completed in 2018. The DuPage river was modeled as a part of this project. The USACE model is largely consistent with the FIS model around the proposed project location. However, the USACE model utilized a different location for the confluence of the DuPage River and West Norman Drain, which was not consistent with the FIS study or current survey data. A copy of the USACE model is included in Appendix P-1 Electronic Files. 6.0 Datum Correlation The datum used for the roadway project is NAVD 1988. While the 2019 FIS elevations are in correlation with the NAVD 1988 datum, the original modeling references the NGVD 29 datum. The 2019 FIS states that the average conversion factor in Will County is -0.284 feet (NGVD 29 – 0.284 = NAVD 88). This conversion factor was used to convert the effective HEC-RAS model to NAVD 88. The datum correlation from the FIS can be seen in Appendix D-1 FIS/FIRM Data. The hydraulic modeling for this project was done in coordination with the NAVD 1988 datum and all values reported in this report and supporting documentation will be based on the NAVD 88 datum. 7.0 Sensitive Flood Receptors The 2019 FEMA Flood Insurance Rate Map (FIRM) shows that there are several homes located near the floodplain. The map in Appendix C-1 Aerial Location Map identifies the homes and their location and critical flooding elevations. The approximate 100-year water surface elevation at each respective location is also listed. However, none of these homes are considered sensitive, as they are all above the 100-year water surface elevation. 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 6 of 12 8.0 Hydrologic Methodology Regulatory flows obtained from the FIS were used for the hydraulic model. The DuPage River discharges at IL 59 for the 10-year, 50-year, 100-year, and 500-year flood frequencies are 6,980 ft3/s, 9,950 ft3/s, 11,280 ft3/s, and 14,700 ft3/s, as shown in Appendix D-1 FIS/FIRM Data. The 2019 FIS states that the flows for the DuPage River were developed by the Illinois State Water Survey (ISWS) using the State Standard Method. These are the same flows used in the 1995 FIS. There are no proposed changes to the flows. To calculate the scour for 200-year design event, the 200-year flows were interpolated from the flows reported in the Flood Insurance Study. The flow calculations are included in Appendix J-2 Scour Analysis. 9.0 Hydraulic Methodology Hydraulic modeling was completed to determine the impacts of the proposed improvements. HEC-RAS version 5.0.5 was utilized to model the DuPage River through the project limits. The effective model of the DuPage river is a HEC-2 model that was imported to HEC-RAS. Three models are included, the base model, existing model, and the proposed model. The base model is the effective model that was imported into HEC-RAS. The existing model represents the existing condition, as well as the natural condition. The proposed model represents the proposed condition. These models were created to evaluate the difference in water surface elevations between the proposed conditions and the existing conditions due the addition of new roadway improvements. Since this is a new bridge alignment, the existing condition represents the natural condition as well. The effective regulatory model for the DuPage River was obtained from FEMA and the geometry was used as a base condition for the required hydraulic analyses on this project. The existing model was revised to incorporate additional cross sections through the project corridor. These cross sections were used in the existing model and the proposed model. The additional cross sections were developed using 1’ contours and streambed surveys. The digital survey data is attached in Appendix P-1 Electronic Files. Corresponding left overbank, right overbank, and channel reach lengths were computed. The cross sections can be seen in Appendix F-1 Detailed Cross Section Location Map and are summarized below in Table 1. Table 1: Cross Section Summary Description River Station Reach Length (ft) Distance to Structure (ft) FEMA XS DO 113205 2,100 5,705 u/s FEMA XS DN 111385 1,445 3,605 u/s FEMA XS DM 109940 802 2,160 u/s Surveyed XS (added) 109190 879 1,358 u/s Surveyed XS (added) 108311 246 479 u/s Surveyed XS (added) 108123 148 233 u/s Surveyed XS (added) 107975 159 85 u/s Surveyed XS (added) 107816 356 73 d/s Surveyed XS (added) 107560 342 429 d/s Unmapped FEMA XS 107340 316 771 d/s Surveyed XS (added) 107024 1,542 1,087 d/s FEMA XS DK 105470 0 2,629 d/s 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 7 of 12 According to the IDOT Drainage Manual, Section 5-301.01, Manning’s n values were computed for the overbanks and channel at each cross section, as shown in Appendix E-4 Manning’s n-Value Computations. The calculated n-value ranges were found to be consistent with those in the FIS model as shown in Appendix D-1 FIS/FIRM Data – Table 10 – Roughness Coefficients (Manning’s “n” Values). Manning’s n for the channel varies from 0.039 to 0.06 and 0.05 to 0.1 for the overbanks and remain consistent throughout the models. The starting water surface elevations were taken from the HEC-2 output and adjusted by the datum conversion where necessary. The HEC-2 output files can be seen in Appendix G-2 Existing Conditions Analysis HEC-2 Input and Output Files. The known water surface elevations were taken at River Station 105470 (FEMA XS DK) and were 603.29 for the 10-year, 604.97 for the 50-year, 605.63 for the 100-year, 605.73 for the 200-year, and 607.18 for the 500-year event. 10.0 Summary of Natural and Existing Hydraulic Analyses 10.1 Natural Hydraulic Analyses Given that no structure currently exists in the corridor of the DuPage River floodplain, the existing model serves as the natural conditions model. 10.2 Base Hydraulic Analyses The effective regulatory model for the DuPage River was obtained from FEMA and used as a base condition for the required hydraulic analyses on this project in order to model the effects of the bridge and roadway. This model was obtained in HEC-2 and was translated to HEC-RAS. The effective model begins at FEMA cross section 105470 (DK), which is 2,629’ downstream of the proposed structure. The base model was truncated at FEMA cross section 113205 (DO), which is 5,705’ upstream of the proposed structure. It is noted that the HEC-2 model cross section convention is left to right looking upstream (the normal convention is left to right looking downstream) and remains that way in HEC-RAS. This base condition HEC-RAS model also remains in NGVD 29 datum, which will be adjusted in the existing condition. The base model represents the HEC-2 model that was received from FEMA and directly imported into HEC-RAS. A comparison of the HEC-RAS base model and the HEC-2 effective FIS Model is shown in Table 1 in Appendix A-2 Summary Tables. The base HEC-RAS model’s water surface elevations were within 0.1 ft of the HEC-2 effective model for the 10-yr, 50-yr and 100-yr event. The base model was used as a base for all developed models. The base model output can be found in Appendix G-3 Existing Analysis HEC-RAS Printouts. 10.3 Existing Hydraulic Analyses The next step was to update the base model with additional cross sections through the project corridor. This model serves as the existing condition. A datum shift was done to reference the NAVD 1988 datum and the existing model cross sections were flipped to match the HEC-RAS convention of left to right looking downstream. New cross sections were developed using 1’ contours and streambed survey data upstream and downstream of the proposed bridge. In order to place cross sections parallel to the proposed roadway FEMA cross section DL was replaced by a surveyed cross section 337 feet downstream and reoriented to avoid cutting into the East 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 8 of 12 Norman Drain floodplain and the proposed roadway embankment. Corresponding left overbank, right overbank, and channel reach lengths were computed for the new cross sections. Ineffective flow areas were added to cross section 107560 (at station 1273.0) and 109190 (at station 1200.0) to account for the lengths that overlapped with the West Norman Drain floodplain. A summary of the FEMA cross sections and the added surveyed cross sections is shown in Appendix F-2 Cross Section Summary. Table 2 in Appendix A-2 Summary Tables compares the existing model to the HEC-2 elevations, adjusted to the NVGD 29 datum, which corresponds to the FIS elevations. The existing model was used as a base for the proposed model. The HEC-2 WSEs were within 0.1 ft of the Existing model for the 10-year, 50-year, and 100-year events at all cross sections except FEMA cross section DM (109940), where the Existing elevations were 0.19 ft and 0.12 ft higher than the HEC-2 model for the 10-year and 50-year event. The slightly higher Existing WSEs at this location are due to the introduction of additional surveyed cross section downstream. The cross section immediately downstream (109190) overlapped with the West Norman Drain floodplain, which required the application of a large ineffective flow area. This addition of neighboring cross sections and ineffective flow area in the Existing Model account for the slightly higher WSE at cross section 109940 compared to the HEC-2 model, which is less accurate at this location due the larger gaps in cross sectional data. The Waterway Information Table can be found in Appendix A-1 Waterway Information Table. The existing waterway opening was not calculated as there is no existing structure. The natural high water elevation was taken from the existing revised model by interpolating the water surface at the upstream face of the bridge using the cross sections upstream and downstream of the proposed bridge, cross sections 107975 to 107816. The distance from the proposed bridge face to the upstream cross section (107975) was taken from the proposed model as 37.15 feet. The existing head is 0 feet because there is no structure at this location, and therefore the headwater elevation is equal to the natural high water elevation. The 10-year velocity through the existing structure was taken as the highest average channel velocity at the upstream and downstream cross sections, cross sections 107975 and 107816. The calculations are shown immediately following the Waterway Information Table in Appendix A-1 Waterway Information Table. 11.0 Proposed Structure Analysis The proposed structure over the DuPage River will consist of a 7-span steel plate girder structure with a total span length of 950 feet. The span lengths from west to east are as follows: 120 feet, 150 feet, 150 feet, 140 feet, 140 feet, 140 feet, and 110 feet with the piers positioned to span the banks of the DuPage River. Structural analysis performed by qualified structural engineers has determined that a 56” plate girder will provide the necessary structural capacity based on the geometry of the proposed bridge. The total bridge depth for the proposed structure is 120”. The low beam of the structure is set at 608.32 (NAVD88). The low chord is 2.0 ft above the 50-year existing (natural) water surface elevation and 0.6 ft above the all time high water level, recorded in the Spring of 2008. The bridge will have two solid walls with circular end piers and four round multi column piers, each not more than four feet in width. Gabion walls will be placed on the west and east banks of the river to protect the proposed piers being placed on each bank from erosion. The bank reconstruction will also protect the 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 9 of 12 existing electric tower that is located on the west bank and south of the proposed bridge. The existing bank is eroding and is threatening the stability of the tower foundation. An open abutment will be located on the west and a vertical abutment on the east side of the bridge. Abutments are set outside the floodway. Pier and abutment skew was determined by the direction of flow during high flow events. The normal channel flow meanders through the floodplain. Piers and abutments shall be parallel to the flood flow direction and not parallel with normal channel flow in order to minimize scour and debris accumulation. The proposed model contains the bridge opening, abutments, piers, low steel elevation, and the roadway profile for crossing the DuPage River. The bridge and roadway do not overtop for flood frequencies up to and including the 500-year flood. The contraction and expansion coefficients were set to 0.3 and 0.5 respectively, at the approach cross section and the upstream and downstream cross sections. Cross sections were modified to incorporate ground line elevation changes. Ineffective flow limits were included for the upstream, 107975 (at station 436.2 and 1453.8) and downstream, 107816 (at station 373.0 and 1352.8) bridge cross sections, as well as cross section 107560 (at station 1273.0) and 109190 (at station 1200.0). The proposed bridge, and new cross section geometry produced water surface elevations that are within 0.1 feet of the existing model water surface elevations as shown in Table 3 in Appendix A-2 Summary Tables. Thus, base flood elevations do not increase by more than 0.1 feet. Modeling was completed to compare conveyance and velocities. For the conversion of the HEC-2 model to the HEC-RAS model, encroachment limits obtained from the HEC-2 output files were input into HEC- RAS. For the Existing model, the floodway limits for added cross sections were obtained from the mapped limits on the FEMA map. The encroachment limits from the Existing model were used for the Proposed model. Conveyance and velocities comparing the Existing to the Proposed condition are shown in the HEC- RAS proposed outlet table in Appendix I-6 Proposed Analysis HEC-RAS Printouts. Regulatory floodway conveyance decreased for proposed conditions only at downstream bridge cross sections whereas the conveyance increased or remained equal at all other cross sections. Velocities did not significantly change and are within acceptable limits for stream scour. As previously discussed, the Waterway Information Table and calculations can be found in Appendix A-1 Waterway Information Table. The proposed waterway opening was calculated by taking the natural high water elevation and the proposed opening and existing channel and calculating the area at the upstream face. The proposed head was calculated by comparing the proposed water surfaces to the existing water surfaces at all cross sections. The maximum value was reported on the Waterway Information Table. The headwater elevation was then calculated by adding the proposed head to the natural high water elevation. The 10-year velocity through the proposed structure is reported from the HEC-RAS bridge output table. 12.0 Scour Analysis Long term degradation has been occurring gradually at the proposed bridge location on the west bank of the DuPage River. Google Earth historical images shown in Appendix J-1 DuPage River Channel Migration show the difference from 1993 to 2018. The channel has migrated approximately 16 feet since 2002. The channel will be stabilized with gabions placed on the east and west banks of the channel to protect the piers and abutments. There is an existing electric tower that is located on the west bank, south of the 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 10 of 12 proposed bridge and based on the Google Earth imagery it appears the bank was stabilized in 2011 to protect this tower. Scour analysis for the proposed bridge was performed in accordance with HEC-18. Scour analysis input variables for the approach cross section (108123) and the contracted section (107900 BR U) were obtained from HEC-RAS as shown in Appendix J-2 Scour Analysis for the 100-year, 200-year, and 500-year events. Scour depths were computed for contraction, pier, and abutment scour through HEC-RAS. Total scour depths are summarized at the upstream bridge cross section (107900 BR U) as well as the total scour depth profile and approximate bedrock elevation at the proposed bridge centerline. Bedrock elevations were estimated from structural borings as shown in Appendix J-3 Boring Logs. The abutment scour analysis was performed using two standard methods, the HIRE method and NCHRP method. The scour depths from both methods were similar, but the HIRE method was used for design. Tabulated summaries of the results for the scour analyses are presented in Appendix J-2 Scour Analysis and below in Table 2. Table 2: Scour Analysis Results Summary (HIRE Method) Elevation Left Ab. Pier 1 Pier 2 Pier 3 Pier 4 Pier 5 Pier 6 Right Ab.

Bedrock 589.99 585.65 585.00 585.00 585.00 585.35 585.61 588.52 The total scour depths for the piers range from approximately 3.6 to 3.9 feet for the 100-year flood, total pier scour depths for the 200-year flood range from 3.7 to 4.1 feet, and total pier scour depths for the 500-year flood range from 3.8 to 4.2 feet. The total abutment scour depths for the east and west abutment are 13.0 and 7.5 feet respectively for the 100-year flood, 14.4 and 11.9 feet respectively for the 200-year flood, and the 500-year total abutment scour depths for the east and west abutments are 17.0 and 3.2 feet respectively. There is no contraction scour for the 100-year, 200-year, or 500-year flow for the channel or overbanks, therefore the total scour is equal to the local scour at each pier and abutment. For protection against scour, the bridge foundations will have structural support to the bedrock elevations, below the scour elevations. Scour countermeasures will also be designed and will be included with the construction plans. 13.0 Compensatory Storage Compensatory storage will be provided for fill placed in the floodplain and floodway of both the DuPage River and West Norman Drain. The compensatory ratio for the Village of Plainfield is 1.5:1. The proposed bridge is crossing the DuPage River upstream of the confluence with the West Norman Drain. This hydraulic report includes compensatory storage calculations for the DuPage River impacts and a separate hydraulic report prepared will document compensatory storage relative to the West Norman Drain. An area located on the west bank and north of the proposed bridge has been selected for compensatory storage to offset fill placed in the floodplain of the DuPage and West Norman Drain. The compensatory 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 11 of 12 storage documentation is included in Appendix L, and includes a cross section location map, fill cross sections, cut cross sections and calculations. 14.0 Permit Requirements The Office of Water Resources/ IDOT Hydraulics requires a floodway permit for impacts to the DuPage River due to the proposed bridge. The following permit requirements are met by the proposed design: • The proposed structure is an appropriate use of the regulatory floodway. • Compensatory storage is provided for all fill in the floodplain. The total amount of required compensatory storage for the DuPage River for the 0 to 10-year range is 5,750 cu yd of storage of which 11,490 of storage is being provided. For the 10 to 100-year range, 4,628 cu yd of storage is required with 6,929 cu yd of storage being provided. • The proposed structure will not increase upstream flood stages greater than 0.1 foot when compared to the revised existing conditions for all flood events up to and including the 100-year frequency event. • The proposed design will not reduce the regulatory floodway storage or conveyance beyond the limits of the proposed bridge. A reduction in conveyance only occurs at the downstream bridge cross sections. • Floodway Velocities are not significantly change from the revised existing to the proposed condition. The Permit Summary form has been completed and is included in Appendix K-1, Permit Summary Form of this report. The Permit Summary form addresses the impacts of the bridge and roadway to the DuPage River and West Norman Drain. As part of the Joint Permit Application, it will be necessary to submit to the Army Corps of Engineers for a Section 404 Permit for impacts to the wetlands. In addition, the Village of Plainfield will need to certify that the improvements are in compliance with the local stormwater ordinance and minimum standards of the Will County Stormwater Management Ordinance. 15.0 Freeboard/ Clearance Section 1-305 of the IDOT Drainage Manual requires a minimum of two feet of clearance between the low beam elevation and the design natural high water elevation. The design natural high water elevation at the bridge is 606.31 feet and the low beam elevation is 608.32 feet. This provides 2.01 feet of clearance. IDOT Drainage Manual Section 1-305 also requires a minimum roadway freeboard of three feet between the design headwater elevation and the lowest pavement elevation within the floodplain. The lowest roadway elevation through the floodplain of 613.31 feet minus the design headwater elevation of 606.37 provides 6.94 feet of roadway freeboard. 16.0 Conclusion Extending 143rd Street east of IL Route 59 will require construction of a bridge to cross the DuPage River. Consideration of hydraulic, structural and highway geometric criteria have determined that a 7-span, 950- foot-long, 4-lane-wide bridge will provide a cost effective and hydraulically adequate means to carry 143RD STREET PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Page 12 of 12 vehicular traffic over the river floodplain. The center span of 150 feet crosses the base flow channel. The bridge construction project will include channel bank stabilization in the immediate vicinity of the bridge and will be designed to protect the proposed bridge piers and stabilize the stream banks. Compensatory storage will be provided on the north side of the bridge along the west bank of the DuPage River. As shown in the scour analysis, scour potential will be mitigated with foundations structural supported to bedrock. Scour countermeasures will also be designed and included in the construction plans for the proposed structure. The necessary freeboard will be provided from the low roadway elevation and the low beam elevation of the bridge and the base flood elevation will not increase by more than 0.1 feet. 17.0 Appendices 143rd STREET EXTENSION PHASE I ADDENDUM HYDRAULIC REPORT NOVEMBER 2019 REVISED: JULY 2020 Appendix A A-1: WATERWAY INFORMATION TABLE This page has been intentionally left blank Printed 7/21/2020 D1 PD0034 (Rev. 01/29/15) Type: n/a Type: Bridge Length/Width: n/a Length Of Span: 950 # Spans/Cells: n/a # Spans: 7 Low Chord: n/a Low Chord: 608.32 Skew: n/a (relative to road) Skew: 10 degrees (relative to road) Clearance: n/a Clearance: 2.01 Bridge Flow Line: n/a (u/s) n/a (d/s) Bridge Flow Line: 594.00 (u/s) 595.28 (d/s) Low E.O.P: n/a Low E.O.P: 613.31 Freeboard: n/a Freeboard: 6.94 Culvert Inverts: n/a (u/s) n/a (d/s) NOTE: Proposed Structure Details Are Preliminary; Subject to Refinement In TSL Stage.
