2.1 Surface Water Features
Th e project is within the Truckee River watershed and
is located approximately 0.75 miles south of the river.
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.

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

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.

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.

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

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.
