4.9.0 Introduction

This chapter describes existing land uses in the vicinity of the Sierra Pacific Power Company (SPPCo) 625 and 650 Line Upgrade Project (project) and analyzes potential land use impacts that may result from construction and operation of the project. Construction of the project will not result in any significant impacts to existing or proposed land uses, nor will the project physically divide an established community. With SPPCo’s ongoing coordination efforts with the Tahoe Regional Planning Agency (TRPA) and local agencies, the project will be compatible with all applicable land use plans and policies adopted by local governments. Therefore, there will be no impacts to land use and planning as a result of the construction, operation, or maintenance of the proposed facilities.

4.9.1 Methodology

The land use analysis involved a review of various city, county, and regional land use plans, policies, and regulations. Land use and policy information from the Placer County, TRPA, and Town of Truckee official websites was reviewed. Personal communication with local agency representatives and site visits to the project area confirmed existing land uses and jurisdictions. The land use analysis also included a review of applicable general plan and zoning maps covering the project area. Land use-related Geographic Information System (GIS) data was obtained from the Placer County Planning Department and TRPA, and was used to verify jurisdictional information collected. A review of United States (U.S.) Forest Service (USFS) plans was performed to confirm jurisdictional boundaries and identify applicable management practices and standards.

4.9.2 Existing Conditions

Regulatory Background

Pursuant to Article XII, Section 8, of the California Constitution, the California Public Utilities Commission (CPUC) has exclusive jurisdiction, in relation to local government, to regulate the design, siting, installation, operation, maintenance, and repair of electric transmission facilities. Other state agencies have concurrent jurisdiction with the CPUC. Although local governments do not have the power to regulate such activities, the CPUC encourages, and SPPCo participates in, cooperative discussions with affected local governments to address their concerns where feasible. As part of the environmental review process, SPPCo has considered relevant regional and county land use plans, policies, and issues, and has prepared this evaluation of the project’s potential impacts to land use and planning. Applicable policies and a discussion of the project’s consistency with those policies are contained in Attachment 4.9-A: Policies Consistency Analysis.

The project’s 650 Line traverses approximately 1.4 miles of the Martis Creek Lake National Recreation Area. In addition, a construction staging area is proposed within the Martis Creek Lake National Recreation Area (see Figure 4.14-1: Recreational Areas Map). This recreation area is managed by the U.S. Army Corps of Engineers (USACE), and the project will be subject USACE permitting requirements for work within jurisdictional waters of the U.S in this area. There are no policy documents or management manuals for the Martis Creek Lake National Recreation Area.

Portions of the 650 Line and the majority of the 625 Line are located on lands managed by the USFS within the Tahoe National Forest and in the Lake Tahoe Basin Management Unit. Those portions of the project are subject to the management standards and guidelines contained in the Forest Plans for both the Tahoe National Forest and Lake Tahoe Basin Management Unit. These plans offer forest-wide standards, guidelines, and management practices for the management of forest ecology and recreational amenities within their jurisdictions. The plans also provide guidelines for the implementation and restoration of projects within the forest boundaries. The project will require a Special Use Authorization from the USFS for work on forest lands within the Tahoe National Forest and the Lake Tahoe Basin Management Unit, and a Timber Sale Agreement for the removal of merchantable timber on forest lands, as described further in Chapter 3 – Project Description.

The project is also subject to the land use regulations and development requirements of the TRPA. In the 1960s, the governors and lawmakers in California and Nevada approved a bi-state compact that created a regional planning agency to oversee development in Lake Tahoe. In 1969, the U.S. Congress ratified the agreement and created the TRPA. The TRPA land use regulations are contained in the agency’s Regional Plan, which is divided into Plan Area Statements (PAS) for their applicable community areas, as shown on Figure 4.9-1: TRPA Community Plan Areas Map. PAS supplement and elaborate on the Placer County General Plan for the area they cover. The project is subject to the following PAS:

The TRPA does not have traditional zoning designations for parcels located within its jurisdiction. Instead, each PAS designates a Land Use Classification (general plan designation) and a list of Permissible Uses (zoning). These are described further in the following sections.

Existing Land Uses and Land Use Designations

This section summarizes the existing land uses, designated land uses, and zoning designations crossed and adjacent to the project, and includes a detailed account of the same in Table 4.9-1: Existing and Designated Land Uses. Figure 4.9-2: Land Use Jurisdiction Overview Map depicts the jurisdictional land use boundaries of the Town of Truckee, Placer County, and TRPA. Maps detailing the land use designations for these jurisdictions are provided in Figure 4.9-3: TRPA Land Use Designations Map, Figure 4.9-4: Placer County Land Use Designations Map, and Figure 4.9-5: Truckee Land Use Designations Map.

Existing 625 Line

Existing Land Use

The existing 625 Line is located entirely within the unincorporated area of northeastern Placer County and generally follows an existing, partially-paved road (Mount Watson Road, otherwise known as the Fiberboard Highway) that is utilized for recreational and forestry-related activities. As depicted in Figure 4.14-1: Recreational Areas Map, approximately 13.4 miles of the approximately 15.3-mile-long transmission line is located on land managed by the USFS. The remaining portion of the line is located on privately owned land.

The existing 625 Line originates at the Kings Beach Switching Station at milepost (MP) 0.0, which is located within the Kings Beach Diesel Generation Station, and situated north of the intersection of Deer Avenue and Speckled Avenue in Kings Beach. The area surrounding the Kings Beach Switching Station is heavily forested and contains hiking, camping, and general recreation facilities. As the line leaves the station, it heads in a northerly direction, until approximate MP 1.3. Along this section, there are 54 single-family homes located approximately 30 feet west of the line, and forested USFS land to the east. At approximate MP 1.3, the line turns west for 2.5 miles and spans State Route (SR) 267 at approximate MP 3.8. This portion of the line is located within heavily forested areas of the USFS Lake Tahoe Basin Management Unit and the Tahoe National Forest. The area is undeveloped, except for dirt access roads and recreational trails. Table 4.9-2: Residences within 1,000 Feet provides a list of the residences near the project components.

ote that in all areas where residences are located w

ithin 1,000 feet of the existing and new 625 L

ine, the lines run coincident.



From the intersection with SR 267, the existing 625 Line heads southwest and continues across Lake Tahoe Basin Management Unit and Tahoe National Forest lands for 6.2 miles. The nearest development is the Northstar-at-Tahoe Resort, which is approximately 0.55 mile north of the existing 625 Line, between approximate MP 7.0 and MP 9.0. The line then heads south for approximately 3.2 miles, turns east for approximately 0.5 mile, and runs adjacent to the southern border of Burton Creek State Park from approximate MP 13.1 to MP 13.6. From this location, the 625 Line turns to the south and continues through the Tahoe National Forest between approximate MP 13.7 and MP 15. This entire portion of the existing 625 Line travels through heavily forested USFS land that is undeveloped, except for dirt roads and recreational trails.

After spanning California SR 89 and the Truckee River at approximate MP 15.1, the line turns in a northeasterly direction and parallels the Truckee River until terminating at the Tahoe City Substation at approximate MP 15.3. This portion of the line is bordered by the Truckee River to the north and the USFS-owned 64-Acres Parkwhich is comprised of recreational trails, restrooms, picnic areas, public restrooms, and parkingto the south. The existing 625 Line terminates at the Tahoe City Substation located on the west side of SR 89, across from the Truckee River Outlet (Fanny Bridge). The area surrounding the transmission line and the Tahoe City Substation is commercially developed with restaurants and tourism-related uses.

Land Use Designations

As shown in Table 4.9-1: Existing and Designated Land Uses, the majority (approximately 80 percent) of the existing 625 Line is located within the regulatory jurisdiction of the TRPA, due to its location within the Lake Tahoe Basin. Placer County regulates the land use of the remaining 20 percent of the line.

The applicable TRPA PAS classify the majority of the land crossed by the existing 625 Line as either Recreation or Conservation. Approximately 0.2 mile of the existing 625 Line (approximate MP 15.1 to MP 15.3) near the Tahoe City Substation is classified as Commercial/Public Service. All TRPA PAS classifications allow electric transmission lines and receiving facilities under the provisions for a Special Use.

There are two segments of the existing 625 Line—where the line spans SR 267 (approximate MP 2.8 to MP 4.2) and just west of the Watson Creek Plan Area (approximate MP 8.5 to MP 10.0)—where land use is dictated by Placer County. The Placer County General Plan has designated the land use within these segments as Forest 40-640 Acre Minimum (in that the minimum lot size is 40-640 acres) and Open Space along SR 267. The Forest 40-640 designation is applied to mountainous areas where the primary land uses relate to the growing and harvesting of timber and other forest products. The Open Space designation along SR 267 is meant to preserve the scenic viewshed from significant development. These segments are zoned Forestry (FOR), Timberland Production (TPZ), and Open Space (O). The allowed uses in the FOR, TPZ, and O zoning districts include growing and harvesting of timber and other forest products, agriculture and grazing, as well as public and commercial recreational uses. Transmission lines are listed as an allowed use in the FOR, TPZ, and O zoning districts.



New 625 Line

The new 625 Line will generally follow the path of the existing 625 Line; however, the alignment will more closely parallel Mount Watson Road to facilitate better access to the transmission line for operation and maintenance activities. The majority of the alignment traverses forested lands within unincorporated Placer County or areas managed by the USFS for timber production and recreational uses. Because the new 625 Line will follow a similar alignment as the existing 625 Line, the same types of existing land uses are encountered (forest, conservation, recreation). Single-family residences are encountered by the new 625 Line in the same locations as the existing 625 Line (near the beginning and end of the lines where they run coincident).

The new 625 Line departs in course from the existing 625 Line primarily between approximate MP 3.6 and MP 13.5. However, in this section the new alignment is within 1,000 feet of the existing alignment. The existing land uses in this area are the same for both the new and the existing 625 lines. The new alignment for the 625 Line will not cross any new TRPA Plan Areas, general plan designations, or zoning districts that are not already crossed by the existing 625 Line alignment and discussed in the previous section. Table 4.9-1: Existing and Designated Land Uses provides the existing and general plan-designated land uses for the project.

650 Line

Existing Land Use

The portion of the 650 Line to be upgraded begins at MP 0.0, which is located approximately 2,000 feet from Bob Haslem Court in the Martis Creek Lake National Recreation Area. The line continues for approximately 1.4 miles, crossing SR 267 at approximate MP 1.4. The line turns east and parallels SR 267 for approximately 0.5 mile, entering the Tahoe National Forest near approximate MP 2.1. This area is generally known as the Martis Valley. Geographically, the area is primarily flat and lacks any significant development. The nearest housing or commercial development—the Northstar-at-Tahoe Golf Course—is more than 1,000 feet south of the transmission line.

After exiting the Martis Valley, the line continues to follow SR 267 in a southern direction for approximately 6.1 miles. The land surrounding SR 267 lacks significant commercial or residential development and is heavily forested. The only significant development is located to the west of approximate MP 3.1, where the Northstar-at-Tahoe Resort is located.

Near the intersection of SR 267 and North National Avenue at approximate MP 7.6, the line travels east. At approximate MP 8.4, the line travels south for approximately 0.5 mile. Residential uses are clustered near the transmission line in this area. Table 4.9-2: Residences within 1,000 Feet provides the approximate distances of residences in close proximity to the project components.

From this point (approximate MP 8.9), the existing 650 Line travels approximately 0.2 mile southeast, finally terminating at the Brockway Substation. This 0.2-mile-long segment of transmission poles has a distribution underbuild. The poles will remain in place (leaving the distribution underbuild intact) but will be topped, and the 650 Line will be relocated to terminate at the Kings Beach Substation. The area around the Brockway Substation, where the line will be



topped, is located within a mixed industrial/commercial neighborhood, and is surrounded by single-family residences to the east, west, and south.


The 650 Line traverses areas where land use is dictated by both Placer County and the TRPA. From MP 0.0 (in Martis Valley) to approximate MP 6.2 (just past the Brockway Summit), the line is located within the jurisdiction of Placer County and is within the Martis Valley Community Plan area. The general plan designation, as described in the community plan, is Open Space, which allows for low-intensity public and commercial recreational uses, as well as necessary public utility facilities. The area is also zoned Open Space, where allowed uses include recreation, crops, forestry, grazing, and utility transmission facilities.

From Brockway Summit to the termination of the line at the Kings Beach Substation, the TRPA regulates land use. The TRPA Martis Peak PAS describes the land use designation as Conservation, with a small portion (0.6 mile) designated as Residential. The permitted uses include summer homes, and recreational uses such as campgrounds, snowmobile courses, and hiking trails. Electric transmission lines and receiving facilities are allowed under the provisions for a Special Use.

132/650 Line Double-Circuit

Existing Land Use

The section of the 132 Line that will be reconfigured to accommodate a double-circuit of the 650 Line is located within the Town of Truckee. The 132 Line originates at the North Truckee Switching Station. The line runs east along Pioneer Trail Road and then turns south, crossing Interstate 80 at approximate MP 0.3. In this area, the line is surrounded by medium-density commercial and industrial developments, such as tire shops, repair businesses, and general offices.

The line then turns east and travels parallel to Glenshire Drive for approximately 0.6 mile between approximate MP 0.5 and MP 1.1. This area contains many undeveloped parcels, as well as low-intensity industrial uses and materials storage yards. The Truckee Lumber Mill is located to the south of the alignment.

The 132 Line then crosses the Truckee River between approximate MP 1.1 and MP 1.2. From approximate MP 1.2 to MP 1.4, the alignment travels along the easternmost edge of the Truckee River Regional Park, which provides ball fields, an amphitheater, a skate park, and rodeo grounds. Adjacent to this portion of the line on the west side of the right-of-way (ROW) are residential uses (multi-family units).

The line continues south through private open space to its termination at the intersection of Marc Trail and Chris Course at the northwest corner of the Village Green Mobile Home Park (approximate MP 1.5 to MP 1.6). In this area, the line spans the rear of a hotel parking lot then travels parallel to the backyards of five units at Village Green Mobile Home Park. Vacant land is located to the west of the line in this area.




The 132 Line is entirely within the Town of Truckee and land uses are dictated by the Town of Truckee General Plan and Town of Truckee Development Code (zoning ordinance). Portions of the alignment, as it travels along Glenshire Drive and near downtown Truckee between approximate MP 0.3 and MP 1.0, are also located within the Downtown Specific Plan Area.

From the beginning of the line at the North Truckee Switching Station to Glenshire Drive (approximate MP 0.0 to MP 0.5), the area is comprised of commercial and industrial uses consistent with the general plan designation of Industrial (I) and zoning designation of Manufacturing (M). As the alignment travels south, the land is General Plan-designated High Density Residential and Public. This urbanized area consists of lands that are zoned I, PF, Resource Conservation, and Downtown Manufacturing, and High Density Residential – 6 to 12 dwelling units per acre (du/ac). These designations permit a wide range of residential, general commercial, industrial manufacturing and processing, distributions, storage uses, as well as parks and other public-serving facilities, including utility lines.

The line travels east along Glenshire Drive and the south, crossing the Truckee River between approximate MP 1.1 and MP 1.2. This area is generally designated as Open Space, Recreation, and Public (Truckee River Regional Park). This portion of the alignment is zoned Recreation (REC) and PF. Allowed uses under the REC zoning designation include camping, skiing, golfing, clustered lodging, residences, transmission lines and support services. Allowed uses under the PF zoning designation include public parks and facilities, transmission lines, schools, hospitals and government offices, and other appropriate uses for public agencies.

The line continues south crossing Brockway Road just after approximate MP 1.5, then continues to the termination of the line just after approximate MP 1.6. The line passes through parcels that are General Plan-designated Commercial and High Density Residential – 6 to 12 du/ac. This area is zoned Commercial General and Residential Multi-Family – 15 du/ac (RM-15), which permit commercial uses and high-density residential uses and development, respectively.

Northstar Tap/Fold

Existing Land Use

The Northstar Tap/Fold begins at the Northstar Substation, located at the end of Stable Road in the Northstar-at-Tahoe Resort area. This 0.5-mile-long section of line generally traverses forested areas adjacent to an existing dirt road. There is limited commercial development located to the north between approximate MP 0.3 and MP 0.4. In addition, a horse stable and riding ring are crossed by the existing Northstar Tap at approximate MP 0.1 near the line’s origin at the Northstar Substation. The tap will be removed upon completion of construction of the new Northstar Fold, which will be located 35 feet south of the existing Northstar Tap.


Land use along the Northstar Fold is regulated by Placer County. The parcels traversed by the line are designated Forest 40-640, High Density Residential, and Open Space. The area is zoned TPZ. Allowed uses include forestry and timber-related uses, grazing, recreation, and transmission lines. Approximately 250 feet of the line (located between approximate MP 0.1 and



MP 0.2) traverses land that is General Plan-designated High Density Residential – 10 to 15 du/ac and zoned Residential Multi-Family – 15 du/ac. These designations allow residential development and some accessory uses, as well as transmission lines.

Substations

Brockway Substation

The Brockway Substation is located in Kings Beach at the intersection of Speckled Avenue and Deer Street. This substation is the current terminus of the existing 650 Line. This substation will be decommissioned at the end of the project and the site will be reclaimed. The substation is located in a mixed-use neighborhood, with an industrial use located to the east of the substation and single-family residences located approximately 100 feet to the north, west, and south.

Land use in and around the Brockway Substation is regulated by the TRPA and the Kings Beach Industrial Community Plan. The Kings Beach Industrial PAS has designated the land use of this area as Commercial/Public Service. The site is not zoned, but rather permissible uses are set forth in the PAS. These permissible uses include auto repair, warehousing and distribution, hardware sales, and small-scale manufacturing. Transmission and receiving facilities, as well as electric transmission lines, are allowed per the PAS under the provisions for a Special Use.

Northstar Substation

The Northstar Substation is located near the intersection of Stables Road and Northstar Drive in Placer County. This substation is the current termination point for the Northstar Tap, which will be upgraded to a fold as part of the project. The substation is surrounded by forested area to the north, south, and west. A riding stable (Northstar Stables) is located to the east of the substation. Approximately 25 single-family residences are located 450 feet west of the Northstar Substation.

Land use around the substation is regulated by Placer County. The site is designated as Forest 40-640 by the Placer County General Plan and the zoning designation is FOR-B-X. The FOR zoning classification designates the area as Forest and the B-X is a combining district designation that defines the minimum buildable lot size, in this case 160 acres. Allowed uses in the FOR-B-X zoning district include forestry and timber-related uses, grazing, and recreation. Transmission lines are an allowed use; public utility facilities are allowed with a Minor Use Permit.

Squaw Valley Substation

The Squaw Valley Substation is located at the intersection of Squaw Valley Road and SR 89. A small, commercial center containing a 7-11 retail store and a ski rental facility is located to the east of the site, Squaw Valley Road is located to the south, and forested land is located to the west and north.

Land use surrounding the substation is regulated by Placer County. The land is designated Conservation Preserve and zoned Forest Residential. Allowed uses include single-family residences, timber harvesting, riding and hiking trails, ski-related uses, and public utility structures.



Tahoe City Substation

The Tahoe City Substation is located near the intersection of Westlake Boulevard/SR 89 and Tahoe Tavern Road. This substation is the current termination point for the existing 625 Line. A restaurant is located to the north of the Tahoe City Substation and forested, undeveloped parcels are located to the south. The Truckee River is located to the west and commercial and tourism-related uses are located to the east. The 1-acre, undeveloped parcel adjacent to the south side of the substation is managed by the USFS, and will serve as a temporary work space, housing portable transformers during construction of the substation.

The substation site is within the jurisdiction of the TRPA and is subject to the land use regulations contained in the Tahoe City Community Plan and Tahoe City PAS. The Community Plan divides the greater Tahoe City area into five Special Areas that are characterized differently depending on their location and level and type of development. The Tahoe City Substation site is classified as Commercial/Recreation and is located in Special Area 3, which lists the permissible uses as employee housing, retail and general commercial uses, public facilities, and recreational-related uses, such as marinas and snowmobile trails. Transmission and receiving facilities, as well as electric transmission lines, are allowed per the PAS under the provisions for a Special Use.

Truckee Substation and North Truckee Switching Station

The Truckee Substation serves as the point of origin for the 650 Line. The substation is located near the intersection of Donner Pass Road and Church Street in the Town of Truckee. The Truckee Substation site is relatively flat and is surrounded by industrial uses on all sides. The substation is designated as Public by the Town of Truckee General Plan and is zoned PF. Auxiliary uses required to meet the needs of the town, such as public parks and other facilities, schools, and government offices, are allowed. Electric utility facilities are allowed with a Use Permit.

The North Truckee Switching Station is located on Pioneer Trail Road, just south of Comstock Drive, and will serve as the point of origin for the 650 Line upon completion of the project. The switching station is surrounded by commercial and industrial uses to the south and east. A cement manufacturing plant is located to the north and undeveloped forested parcels are located to the west. The North Truckee Switching Station is located within the Town of Truckee. The Town of Truckee General Plan designates the land as Industrial and the zoning as Manufacturing/Industrial (M). Allowed uses include processing, distribution, and storage facilities. Electric utility facilities are allowed in the M zoning district with a Use Permit.

Kings Beach Substation

The Kings Beach Switching Station, which will become the Kings Beach Substation, is located inside the Kings Beach Diesel Generation Facility, just north of the intersection of Speckled Avenue and Deer Street in Kings Beach. The switching station is located off of a private access road north of Deer Street. The switching station is entirely surrounded by undeveloped and forested parcels.

The Kings Beach Substation is within the jurisdictional area of the TRPA; the land use regulations that apply to the site are contained in the Martis Peak PAS. The land use



classification for the site is Conservation and the list of permissible uses per the PAS includes camping, off-road vehicle uses, public services, timber harvesting, and summer homes. Electric transmission and receiving facilities are allowed per the PAS under the provisions for a Special Use.

Staging Areas

To support construction, SPPCo is proposing to use seven staging areas. These staging areas are depicted on Figure 4.9-2: Land Use Jurisdiction Overview Map and are described further in the following paragraphs.

Joerger Road

The Joerger Road Staging Area will be located off of an existing dead-end paved road and will be accessed using Joerger Road. This approximately 600-foot by 200-foot staging area will be used as a material staging area and a helicopter landing, storage, and refueling area. The site is located within the Town of Truckee. The site is General Plan-designated Public and is zoned PF. The development code (zoning ordinance) for the town of Truckee does not specifically have a use category for temporary construction staging; however, recycling facilities, vehicle storage, snow removal businesses, mining, and heliports are allowed. A temporary construction staging area is similar in nature to the specified allowed uses.

Northstar Golf Course

The Northstar Golf Course Staging Area is located just north of SR 267 and the Northstar Golf Course, and is accessed by a dirt road located approximately 1.4 miles southeast of Martis Creek Road. This approximately 300-foot by 300-foot staging area will be used to store materials and stage equipment. The site is located within the jurisdiction of Placer County. The site is General Plan-designated Open Space and is zoned O. Allowed uses include recreation, crops, forestry, grazing, and construction staging and storage as an accessory use (provided the staging area serves an active, permitted construction project).

Kings Beach

The Kings Beach Staging Area is located just north of the Kings Beach Substation and is accessed using an existing dirt access road located at the end of Canterbury Drive. This location was formerly used as a landfill and as a result, has a previously disturbed area that measures approximately 300 feet by 300 feet. The site is located within the Martis Peak Plan Area. The Martis Peak PAS classifies the land as Conservation and the list of permissible uses per the PAS include camping, off-road vehicle uses, public services, timber harvesting, and summer homes. A staging area is allowed by the TRPA provided the staging area is temporary in nature, is constructed with the proper Best Management Practices to avoid increased stormwater pollution, and has no visual impacts.

Sawmill Flats

The Sawmill Flats Staging Area is located approximately 0.4 mile north of the new 625 Line near approximate MP 6.2 and is accessed by an existing dirt access road from Mount Watson Road. This staging area will be used to store and stage material and equipment, and may also be used for logging activities related to the project. This approximately 500-foot by 260-foot area is



previously disturbed and denuded. The site is located within Placer County and is General Plan- designated Forest 40-640 and zoned TPZ. Forestry-related uses and accessory storage are allowed uses at the site.

Former Batch Plant

The Former Batch Plant Staging Area is located approximately 300 feet north of the new 625 Line near approximate MP 9.3 and is accessed from Mount Watson Road. This approximately 120-foot by 80-foot area is previously disturbed and has little natural vegetation directly within the staging area. This staging area is located within the jurisdiction of the TRPA and the land use designation and allowed uses are described in the Northstar PAS. The site is designated Recreation per the PAS, and utility facilities, timber management, and assessor structures are allowed uses. A staging area is an allowed use by the TRPA, provided the staging area is temporary in nature, is constructed with the proper Best Management Practices to avoid increased stormwater pollution, and has no visual impacts.

Fiberboard Highway

The Fiberboard Highway Staging Area is located approximately 200 feet east of the new 625 Line near approximate MP 12.8 and is accessed from Mount Watson Road. This approximately 200-foot by 100-foot area is previously disturbed but has some vegetative cover. The staging area is located on lands where the allowed uses are designated within the Burton Creek PAS. The staging area is designated Conservation, which allows for a range of low to moderate uses, including timber harvesting, wildlife management, grazing of livestock, and recreation. A staging area is an allowed use by the TRPA provided it is temporary, will not contribute to stormwater pollution, and will not contribute to visual impacts. Tahoe City

The proposed Tahoe City Staging Area will be located on an undeveloped, but previously disturbed parcel located 1 mile north of the Tahoe City Substation and is accessed by an existing dirt access road from Jackpine Street. This staging area will be used as a helicopter landing zone and for material storage and staging. This approximately 600-foot by 250-foot area is previously disturbed and covered in pavement and gravel. The site is located in the Tahoe City Industrial Plan Area. The applicable PAS classifies the land as Commercial/Public Service and permissible uses include storage yards, warehousing, building materials and hardware storage, and industrial services.

Planned Development

There are several planned developments in the vicinity of the project. Projects that are directly adjacent or crossed by the 625 and 650 Line Upgrade Project are summarized in this section. A detailed inventory of all planned and proposed projects is provided in Table 4.17-1: Planned and Proposed Projects Within 5 Miles in Section 4.17 Cumulative Impacts.

The only project immediately adjacent to or crossed by project components is the Tahoe City Transit Center, which is proposed for construction in the 64-Acres Park beginning in 2010. Construction is scheduled to be completed in 2011. The project is immediately adjacent to the



south side of the Tahoe City Substation. The proposed transit center will consist of a parking lot, bus shelters, new landscaping, and new roads and pedestrian paths.

Habitat Conservation Plans and Natural Community Conservation Plans

The project components are not located within the boundaries of any habitat conservation plan (HCP) areas or natural community conservation plan (NCCP) areas.

Land Use Policies

All of the general plans adopted by local jurisdictions, TRPA regional and community plans, and USFS Forest Plans applicable to the project were reviewed for relevant land use policies. The relevant policies and an analysis of the project’s consistency with them are provided in Attachment 4.9-A: Policies Consistency Analysis.

4.9.3 Impacts

Significance Criteria

Standards of significance were derived from Appendix G of the California Environmental Quality Act (CEQA) Guidelines. Impacts to land use will be considered significant if the project:

Physically divides an established community, resulting in a change to the community or land use pattern

Conflicts with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to, the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect

Conflicts with any applicable HCPs or NCCPs

Question 4.9a – Physical Division of an Established Community

Construction – No Impact

Existing 625 Line

The existing 625 Line does not currently divide a community as the line travels primarily through sparsely populated, forested areas of north Lake Tahoe. Because the existing 625 Line will be removed in its entirety and the ROW will be allowed to revegetate naturally, no new impact will occur. Therefore, there will be no impact.

New 625 Line

The new 625 Line will roughly parallel the existing 625 Line ROW and Mount Watson Road. In addition, the new alignment of the 625 Line will be located in predominantly forested, undeveloped, or sparsely developed areas within the Lake Tahoe Basin. As a result, the new transmission line will not physically divide an established community.

Impacts from construction to the approximately 95 single-family residences and two multi-family residences (unit count unknown) within 1,000 feet of the transmission line and the



commercial area near the line’s terminus will include an increased dispersal of dust, noise, and odor that will be localized, temporary, and short-term. These impacts are described more thoroughly in Section 4.3 Air Quality and Section 4.11 Noise.

650 Line

The existing 650 Line—from MP 0.0 until its new terminus at the Kings Beach Substation—will be rebuilt in place within the existing ROW which varies in width, but averages approximately 30 feet wide. To accommodate construction, an additional 35 feet of temporary ROW will be required adjacent to the existing easement. The 650 Line traverses predominantly undeveloped land and parallels SR 267 for the majority of its length. With the decommissioning of the Brockway Substation, the terminus of the 650 Line will be relocated to the Kings Beach Substation. The conductor on the poles between the Kings Beach Substation and Brockway Substation will be removed and the poles will be topped, leaving the distribution and telecommunications/cable underbuilt lines intact. Temporary impacts to the residences near Brockway Substation from conductor removal and topping the poles will include an increased dispersal of dust, noise, and odor that will be localized, temporary, and short-term. These impacts are described more thoroughly in Section 4.3 Air Quality and Section 4.11 Noise.

Because the 650 Line will be rebuilt in place and/or relocated within an existing easement that parallels existing linear features, no new physical divisions of established communities will occur. As a result, there will be no impact.

132/650 Line Double-Circuit

On the 132 Line, approximately 32 poles will be replaced and the line will be reconfigured to allow a double-circuit configuration with the 650 Line and operation at 120 kilovolt. The new, steel poles will be located within the existing 40-foot-wide easement, approximately 10 feet from the current wood pole locations. To accommodate construction, an additional 25 feet of temporary ROW will be required adjacent to the existing easement. As previously described, impacts from construction to the nearby residential and commercial areas will include an increased dispersal of dust, noise, and odor, and will be less than significant. While the 132 Line is located in a more populous, urbanized area, as compared to the other project components, all work will be conducted within, and immediately adjacent to, the existing easement held by SPPCo. As a result, there will be no impact.

NorthstarTap/Fold

The Northstar Fold will be constructed in a new 40-foot-wide easement located approximately 35 feet south of the existing Northstar Tap. Upon completion of the new Northstar Fold, the existing Northstar Tap will be removed. The alignment for the Northstar Tap and Fold generally follow existing dirt roads that traverse primarily undeveloped, forested land. The only developments in the vicinity are a small commercial/industrial storage area and horse stables, which are located north of the line. Because the Northstar Fold will be constructed adjacent to the existing easement for the Northstar Tap and because the area is not located within an established community, no physical divisions of established communities will occur.



Substations and Switching Stations

With the exception of the Kings Beach Substation, the upgrades and modifications to the substations and switching stations will take place within the current footprints of the existing facilities. Some activities at the Kings Beach Substation will take place outside of the existing substation footprint, but within the SPPCo-owned parcels.

Temporary transformers will be placed on an adjacent parcel to the south of the Tahoe City Substation. The site has been previously disturbed by construction activities. The site will be utilized for the installation of temporary transformers during the duration of construction. The site will be revegetated after the temporary transformers are removed so there is no long-term impact. In addition, locating temporary transformers on the adjacent site will not divide an established community because there is no development located at the site.

Because activities at the substations and switching stations will take place within or immediately adjacent to existing facilities and will be limited to SPPCo-owned land (except for the Tahoe Substation temporary transformer site), the proposed upgrades and modifications will not physically divide an established community.

Staging Areas

All of the staging areas proposed for use on this project are located in undeveloped and previously disturbed areas. Thus, temporary use of these areas during construction will not physically divide an established community and there will be no impact.

Operation and Maintenance – Less-than-Significant Impact

With the exception of portions of the new 625 Line, the Northstar Tap/Fold, and minor improvements to the 650 Line, the project components will be operated and maintained within existing easements held by SPPCo or on SPPCo-owned property. While a new, approximately 40-foot-wide, permanent easement will be required for the operation and maintenance of the new 625 Line and the Northstar Tap/Fold, the transmission line will be located in predominantly forested, undeveloped land and will follow existing linear features for much of its length. In addition, SPPCo operation and maintenance practices will not change significantly from existing practices, and will not result in any physical division of communities because they will be conducted within ROWs and substation facilities. Therefore, operation and maintenance of the proposed facilities will not result in a physical division of an established community.

Question 4.9b – Plans and Policy Conflicts – Less-than-Significant Impact

As discussed in Attachment 4.9-A: Policies Consistency Analysis, construction, operation, and maintenance of the project will not directly conflict with any environmental plans, policies, or regulations adopted by agencies with jurisdiction over local and regional land uses.

One project, development of the Tahoe City Transit Center, is located immediately adjacent to the existing and new 625 lines and the Tahoe City Substation. Construction will begin at the Tahoe City Transit Center in 2010 and be completed in early 2011. The Tahoe City Transit Center project will be completed by the time construction begins on any portion of the 625 and 650 Line Upgrade Project. However, there is a potential for conflicting uses at the Tahoe City



Transit Center site as SPPCo intends to use a portion of the parcel to temporarily place transformers during construction on the 625 Line and at the Tahoe City Substation. In order to ensure that the temporary transformers will not interfere with operation of the Tahoe City Transit Center, SPPCo will coordinate with the USFS and Placer County well in advance of construction to obtain permission to use the parcel. SPPCo will work to site the temporary transformers in undeveloped areas or in area designated for parking. As a result, the impact will be less than significant.

Question 4.9c – HCP or NCCP Conflicts – No Impact

The project components are not located within the boundaries of any HCP or NCCP areas. Thus, no impact will occur.

4.9.4 Applicant-Proposed Measures

Because there will be no new physical divisions of existing communities or direct conflicts with land use plans and policies from implementation of the project, no avoidance or minimization measures are proposed.

Ensure that existing aboveground utilities w

ill normally be undergrounded by

priorities established in the R-5 U

ndergrounding Master P

lan. Y

es

The project involves m

odifications to an existing aboveground utility line and substation facilities. D

ue to high costs, steep topography, and rock-covered terrain, undergrounding the project is not feasible on U

SF

S

land.

C. L

andscaping: The follow

ing should be considered with respect to this

design component of a project:

1) Native vegetation should be utilized w

henever possible. 2) V

egetation should be used to screen parking and to alleviate long strips of parking space. 3) P

lants should be used to give privacy, reduce glare and heat, deflect wind,

muffle noise, prevent erosion, and soften the line of architecture (p. II-49)

Yes

Areas disturbed by construction w

ill be recontoured to blend with

adjacent topography and revegetated with native seed m

ixes. For sites

within the L

ake Tahoe B

asin, this seed mix w

ill be determined in

coordination with the T

ahoe Regional P

lanning Agency (T

RP

A).

Where planting is proposed as part of aesthetic m

itigation measures, as

in AP

M-A

ES

-05 and AP

M-A

ES

-09, native species will be used (refer to

Section 4.1.4 A

pplicant-Proposed M

easures).

D. L

ighting: Lighting increases the operational efficiency of a site. In

determining the lighting for a project, the follow

ing should be considered: 1) E

xterior lighting should be minim

ized with an em

phasis on safety and should be consistent w

ith the architectural design. 2) O

verall levels should be compatible w

ith the neighborhood light level. E

mphasis should be placed on a few

, well placed, low

intensity lights. 3) L

ights should not blink, flash, or change intensity (p. II-49)

Yes

Lighting w

ill only be installed at the Tahoe C

ity and Kings B

each substations, w

ill conform to T

RP

A guidelines, and w

ill be used on an as-needed basis only and not for continuous nighttim

e use. Exterior

lighting will consist of one dow

nward directed lam

p, utilizing a 500-w

att halogen bulb, located at the control building. Existing structures

and landscaping will largely screen substation lighting, and new

landscaping proposed at the T

ahoe City S

ubstation as part of AP

M-

AE

S-05 w

ill further screen views of lighting from

outside the facility. T

herefore, new lighting w

ill be minim

ized and compatible w

ith the surrounding area.

1. All proposed developm

ent shall examine im

pacts to the identified landscape view

s from roadw

ays, bikepaths, public recreation areas, and Lake

Tahoe (p. IV

-21) Y

es S

ection 4.1.3 includes an evaluation of impacts to view

s from public

areas. In particular, key TR

PA

views have been analyzed and generally

determined to be positively affected by the project.

2. Any developm

ent proposed in areas targeted for scenic restoration or within

a unit highly sensitive to change shall demonstrate the effect of the project on

the 1982 Travel R

s: 100 feet from the centerline of

perennial streams, 50 feet from

centerline of intermittent stream

s, and 50 feet from

the edge of sensitive habitats to be protected including riparian zones, w

etlands, old growth w

oodlands, and the habitat of rare, threatened or endangered species (see discussion of sensitive habitat buffers in Part I of this P

arily serve areas outside the B

asin). Y

es

The project does not include constructing a new

transmission system

, but rather involves upgrades to an existing system

. It is being proposed to increase the reliability of the existing north L

ake Tahoe transm

ission system

and accomm

odate planned growth in and around the L

ake Tahoe

Basin. W

hile portions of the facilities are located outside of the confines of the L

ake Tahoe B

asin, the primary service areas are K

ings Beach and

Tahoe C

ity, which are located w

ithin the Lake T

ahoe Basin. T

he transm

ission system also serves the N

orthstar area, which serves as an

important tourist destination in the L

ake Tahoe area. T

he additional capacity provided by the project w

ill accomm

odate the increased electrical dem

ands of the Northstar resort and support increasing tourism

in the L

ake Tahoe region.

TR

PA

R

egional Plan

Expansion of public services and facilities should be phased in to m

eet the needs of new

development w

ithout creating inefficiencies from overexpansion

or under-expansion. Y

es

The S

PP

Co 629 L

ine was upgraded in 2008. S

PP

Co is increm

entally rebuilding the existing system

in the north Lake T

ahoe area. The 625

and 650 Line U

pgrade Project is being proposed in response to current

population projections and existing electrical demand in the north L

ake T

ahoe area. At a 1 percent load grow

th rate, the additional capacity provided by this project w

ould meet the needs of the area for about 20

years. At a 2-percent load grow

th rate, the capacity would be sufficient

for about 11 years.
