Th is portion of the watershed consists of meadows and intermittent channels bounded to the east by the Martis Creek watershed area and bounded to the south and west by sloping topography. Overall the size of the drainage area is approximately 2 square miles. Elevation of its ground surface ranges from about 5,800 feet above mean sea level (msl) along Truckee River to 6,760 at Bald Mountain, a mountain summit that defi nes the southwesterly extent of the watershed. In general, the southerly half of the drainage is dominated by mountainous terrain and steep hillsides with intermittent channels and unnamed tributaries. At the base of the hillside area, there is fl at terrain with woodlands and a series of meadows. Th e meadow areas are dispersed across a broad area along Brockway Road, Highway 267 and the Truckee-Tahoe Airport. In many cases the meadow areas are isolated with no surface connection to Truckee River. Th e project site is located on the northern half of the drainage shed area on the relatively fl at terrain with grasslands, meadows and woodlands. Several independent special service districts and private utility companies provide the range of needed utilities and infrastructure to Truckee, including Joerger Ranch. Th is Chapter outlines the general infrastructure and utility service program for Joerger Ranch to ensure that suffi cient infrastructure is provided to, and within, the Plan Area. Th is Chapter describes the existing infrastructure related to water, wastewater, storm water drainage, electric, gas, phone, cable tv and solid waste disposal in the immediate vicinity of the Joerger Ranch Plan Area, and a general outline of needed infrastructure improvements to serve development within the Plan Area. A Utility & Infrastructure Plan (Figure 5-2) is included, depicting the existing utility locations and likely points-of-connection for water, sewer, telecommunications and electric service to the various subdistricts of the Plan Area. Th e Utility & Infrastructure Plan also indicates known on-site looped connections and improvements necessary to serve Joerger Ranch. Th e ultimate design of these improvements, including their location, size, and capacity, is reliant upon development proposals and coordination and approval with each of the respective service entities. 1 | Introduction 2 | Hydrology & Storm Drainage FIGURE 6-1 6.3 J OERGER RANCH SPECIFIC PLAN P UBLIC SERVICES & INFRASTRUCTURE | C HAPTER 6 Surface runoff is conveyed primarily as sheet fl ow through the project site in a northerly direction toward Truckee River. Th e site contains two intermittent ephemeral drainage courses that are fed from the south by culverts passing under Brockway Road and State Route 267. 2.2 Hydrogeologic Information Th e geological setting for Martis Valley Basin (and the project site) consists of plutonic/metamorphic rock, sedimentary deposits and volcanic deposits. Groundwater level elevations are controlled by the complex stratifi cation of the hydrogeologic units, topographic relief, and groundwater fl ow barriers. Groundwater in the basin is largely fed by precipitation, snow melt and seepage from the mountainous terrain to the southwest. Th e underlying Martis Valley aquifer is the main water supply for the Town of Truckee and other public and private entities. Average precipitation is estimated to be 23 inches in the lower elevations of the northern portion of the basin to nearly 40 inches in the southern areas. Approximately 75 percent of the annual precipitation is received in the winter and early spring months as snow or mixed rain and snow. Precipitation throughout the remainder of the year primarily consists of thunderstorms. 2.3 Project Drainage Th e Joerger Ranch project drainage is defi ned by fi ve drainage shed areas shown in Figure 5-1. Surface Water and drainage will be managed through a combination of natural and built features to conserve water quality, natural hydrology and habitat and preserve biodiversity through conservation of water bodies and wetlands. Low Impact Development (LID) stormwater management strategies will be used to maintain the natural hydrologic function of the site with localized small-scale source control techniques that disperse fl ows and manage runoff close to where it originates. Storm drainage from impervious areas (roads, walks, roofs) will be collected and routed through water quality treatment facilities designed to reduce the rate of runoff to pre-project conditions, remove potential pollutants and facilitate infi ltration. LID Drainage facilities may include Water Quality Inlets; Buff er Strips; Soil Amendments; Earthen swales; Rock-lined swales; Bioswales; Rock Infi ltration Basins; Retention Basins and Slope Stabilization. Th ese facilities will be used to capture sand and sediment, provide fi ltration of pollutants and allow infi ltration to underlying soils. Grading disturbance shall be minimized by use of construction fencing. All graded disturbance areas shall be restored with soil stabilization and natural vegetation through use of organic material such as wood chips, mulch, and native plantings for protective ground cover. Per the guidelines of the State of California, Water Resources Control Board, Lahontan Regional Water Quality Control Board (SWRCB-Lahontan) and as required by Town of Truckee, onsite retention shall be provided for 20-year, 1-hour volume of water from impervious areas. Th is equates to the fi rst 0.7 inches of rainfall from all impervious surfaces including roadways, sidewalks, paved paths, roofs and driveways. Peak discharge fl ows are reduced to rates and quantities at or below existing pre-project FIGURE 6-2 SR 267 CULVERT 6.4 C HAPTER 6 | PUBLIC SERVICES & INFRASTRUCTURE J OERGER RANCH SPECIFIC PLAN conditions by use of onsite retention facilities that attenuate fl ows and provide infi ltration. Snow storage and snow removal are important considerations on-site and within the adjacent public road and highway rights-of-way. Snow will be stored on-site in landscape areas and other undeveloped areas. If the required amount of snow storage cannot be handled on-site, it will be hauled off -site to a permitted disposal site such as the Eastern Regional Landfi ll Transfer Station. Storm water runoff from snow storage areas will be routed through water quality treatment facilities prior to discharge. Snow removal shall be further described in a Maintenance Agreement between property owner and the Town. 2.4 Water Quality Water quality controls for the project shall be implemented in compliance with local, State and Federal requirements. California State Water Resources Control Board (SWRCB) enforces the federal Clean Water Act and Porter-Cologne Water Quality Control Act, including administration of National Pollutant Discharge Elimination System (NPDES) permits. Lahontan Regional Water Quality Control Board (LRWQCB) has surface water and groundwater objectives, prohibitions and guidelines as set forth in the Water Quality Control Plan for the Lahontan Region (Basin Plan). During construction, Best Management Practices (BMP’s) including temporary erosion control facilities shall be implemented to control any pollutants that could potentially aff ect the quality of storm water discharges from the site. A Storm Water Pollution Prevention Plan (SWPPP) will be prepared and the project will comply with the State of California’s General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities. Th is includes implementation, maintenance and inspection of non-storm water and storm water discharge; erosion and sediment control measures; materials and waste management; general site clean-up; vehicle and equipment cleaning, fueling and maintenance; and spill control ensuring that no materials other than storm water are discharged in quantities which will have an adverse eff ect on receiving waters. Post Construction BMP’s will also be implemented in accordance with NPDES Stormwater Phase II and Town of Truckee’s municipal separate storm sewer system (MS4) requirements. Post Construction BMP’s include runoff control measures, water quality facilities, operations and maintenance program, employee training, recycling and waste disposal program and public education (signage/brochures) for storm water protection. Permanent water quality facilities that remain in place upon completion of the project such as bio-swales, retention basins and water quality inlet structures remove and fi lter potential common pollutants such as oil and grease from roadways, pesticides from lawns, sediment, and carelessly discarded trash prior to discharge of storm water to natural water course. 3 | Sanitary Sewer Wastewater collection and conveyance is provided by the Truckee Sanitary District (TSD). Wastewater treatment is provided by the Tahoe-Truckee Sani- tary Agency (T-TSA). Sewage is currently collected primarily by gravity fl ow throughout adjacent devel- oped areas, and is transported in a sewer main line at Joerger Drive for conveyance to the treatment plant located east of the Town of Truckee. Figure 5-3 shows the points of connection and the mainline extensions needed to serve this project. Th e on site sewer line layouts in each sub-District are shown with dashed lines. Final sewer collection system layouts and pipe sizes will depend on the building layouts and will comply with TSD design requirements. 6.5 J OERGER RANCH SPECIFIC PLAN P UBLIC SERVICES & INFRASTRUCTURE | C HAPTER 6 Figure 5-3 also details the existing sewer mainline and the proposed mainline extensions. Each sub-District may build its own stand alone mainline extension and connection, independent of the order of phasing, as described herein. Th e Neighborhood District shall connect to the existing 21” sanitary sewer near its northern boundary. Th e RM-F zoning area at the intersection of Hope Court / Brockway Road shall connect to the existing sanitary sewer in Brockway Road and extend it east along Hope Court. Th e elevation of the existing point of connection will determine how much of the Hope Court site can be served by gravity sewer and whether or not service pumps are required. Development along Joerger Drive shall connect to the existing 21” sanitary sewer at its north boundary. A mainline extension within Joerger Drive is not necessary. Th e remainder of the CRS Zoning area would be required to connect on site by extending the existing 6” sewer stubs along Soaring Way. Final mainline extensions and on site system layouts will comply with TSD design requirements. Each Specifi c Plan area shall provide easements as required by TSD for the public sanitary sewer improvements and access thereto. 4 | Water 4.1 Water Supply Water service in Truckee is provided by the Truckee Donner Public Utility District (TDPUD), a publicly owned utility providing electric and water service since 1927. Th e District operates three water systems in the Truckee area: the Hirshdale System, the Truckee System, and the Donner Lake System. Th e Truckee System serves the Joerger Ranch Plan Area. Existing transmission, distribution and treated water storage facilities will serve both existing and future demand from the planned development. Th is basic infrastructure has developed by TDPUD in accordance with the Water Master Water Plan and is suffi cient to supply the project. Water mainlines are located within the adjacent roadways and will be extended throughout the project site for domestic water distribution and fi re suppression. Th e project water demand is equivalent to, or less than, the amount of water required per the General Plan and TDPUD Water Master Plan. Water consumption will be reduced in accordance with California Green Building Standards Code (CalGreen) water saving mandates through the use of water effi cient fi xtures, fi ttings, fl ow restrictors and irrigation controllers. 4.2 Existing System Figure 5-4 shows the TDPUD water distribution sys- tem in the vicinity of this project. Existing water main sizes are shown. FIGURE 6-3 6.6 C HAPTER 6 | PUBLIC SERVICES & INFRASTRUCTURE J OERGER RANCH SPECIFIC PLAN 4.3 Proposed System Figure 5-4 also shows the points of connection and the water mainline extensions needed to serve this project. Th e layout of these mainline extensions will comply with the TDPUD Water System Master Plan and meet their approval. Th e on site water line layouts in each Specifi c Plan area are shown with dashed lines. Final water line layouts and pipe sizes will depend upon the results of hydraulic analysis that take into account existing system pressures, project elevations, fi re fl ow requirements and domestic demands. Hydraulic analysis will be performed with the existing TDPUD hydraulic model, in accordance with their design requirements. 5 | Energy 5.1 Electric Service Th e Joerger Ranch Project lies within the service area of Truckee Donner Public Utility District (TDPUD).  Existing electrical transmission lines and service distribution lines lie adjacent to and within the Plan Area. Electrical service facilities will be extended from existing TDPUD infrastructure and shall be upgraded as necessary to adequately serve the project as it develops and shall be designed to accommodate ultimate development at build out. Th ese facilities shall be designed and extended as directed by TDPUD and in accordance with TDPUD and California Public Utilities Commission (CPUC) rules. Common trench utilities including electric, natural gas, telephone, and cable TV services shall be located underground within public utility easements. Placement of transformer boxes shall be coordinated with TDPUD. 5.2 Natural Gas Natural gas service is provided to the Truckee area by Southwest Gas Corporation.  Existing natural gas transmission lines and service distribution lines lie adjacent to and within the Plan Area. Natural gas facilities will be extended from existing Southwest infrastructure in Martis Drive and shall be upgraded as necessary to adequately serve the project as it develops and shall be designed to accommodate maximum build out. Th ese facilities shall be designed and extended as directed by Southwest Gas and in accordance with Southwest and California Public Utilities Commission (CPUC) rules. Natural gas lines will be included within the common trench utilities which shall be located underground within public utility easements.

Southwest Gas. 7 | Law Enforcement &Fire Protection 7.1 Law Enforcement Police service in Truckee is provided by the Truckee Police Department. Th e Police Department operates out of its headquarters at 10183 Truckee Airport Road on the easterly terminus / intersection with Soaring Way and less than a ¼ mile from the Plan Area. All calls are responded to from the Department’s headquarters, allowing for a fast response time to the Plan Area. 7.2 Fire Protection Th e Truckee Fire Protection District (TFPD) provides fi re prevention, fi re suppression, emergency medical care and/or transportation, assorted rescue services, and public education services within the Town of Truckee. Th ree TFPD fi re stations are located in close proximity to the Plan Area: Station 91 in Downtown Truckee, Station 92 in the Gateway area, and Station 96 in the Truckee Tahoe Airport area. Th ese three TFPD fi re stations are located and staff ed as follows: Station 91 in Downtown is located in downtown Truckee and houses the Fire Chief’s offi ce, the District’s administrative staff and the Prevention Bureau. Station 92, in the Gateway area, is located next to the Truckee High School and in front of the Sierra Mountain Middle School. It is the District’s largest station with the most equipment. Th e Town of Truckee lies within a high Fire Hazard Severity Zone, as defi ned by the California Department of Forestry, indicating that wildland fi res are considered to pose a signifi cant hazard. Th e level of fi re danger risk within the town ranges from moderate to very high based on the density of development within a particular area and its proximity to forested areas. 8 | Solid Waste & Recycling Solid waste removal and recycling services for the Town of Truckee are provided by the Tahoe-Truckee Sierra Disposal (TTSD) Company. Two separate bodies make up the TTSD: Tahoe Truckee Disposal FIGURE 6-5 6.8 C HAPTER 6 | PUBLIC SERVICES & INFRASTRUCTURE J OERGER RANCH SPECIFIC PLAN (TTD) and the Eastern Regional Landfi ll Material Recovery Facility (MRF). TTD is responsible for collecting household waste and recyclables to the MRF. Th e MRF is the recycling center for household and construction materials that acts as a transfer station for household waste. Incoming solid waste is either recycled or transported to the Lockwood Regional Landfi ll in Storey County, Nevada. Th is 1,535-acre site has a 60-year capacity to accommodate the buildout projections for the TTSD’s service area. Currently, TTSD is in its twelft h year of an 80-year contract for disposal services at the landfi ll. TTD is the collection division of TTSD and operates close to 40 vehicles to collect waste. TTD uses a combination of rear mounting bin pick up trucks for single-family residences and low-density areas, and front loader garbage trucks for commercial and multi- family areas. Funding for solid waste collection comes from collection fees. TTSD handles approximately 60,000 tons of waste per year and is operating at 50 percent of their total capacity of 120,000 tons per year. In 2002, the capacity of the MRF facility and transfer station were increased by 100 percent. TTSD plans on continuing to expand their services to accommodate the growth and increasing needs of their service area. 9 | Mail Service Mail delivery and collection is provided for the Town and surrounding region by the U.S. Postal Service (USPS) from a distribution facility located in Downtown Truckee. Th e project development will include “clustered” type mailboxes – including free- standing, pedestal-mounted cluster box unit (CBU), or other cluster mailboxes mounted in a wall, kiosk, or shelter in accordance with USPS regulations and requirements.
