Draft Environmental Impact Report - California Off Highway Vehicle ...

3.1 Transportation and Traffic
this location is projected to result in LOS F at the southbound approach under Year 2017 weekday
conditions with or without the addition of project‐generated traffic. All other approaches to this
intersection are projected to experience satisfactory LOS A or B delays. An analysis of forecasted
volumes in comparison with California Manual of Uniform Traffic Control Devices for Streets and
Highways thresholds (Warrant 3, Figure 4C‐4) (Caltrans 2010) indicates that the intersection
would not warrant the installation of a traffic signal. A peak‐hour volume of 87 vehicles is
projected at this approach (Figure 3.1‐10), while a threshold of 190 vehicles would be required to
consider the installation of a traffic signal.
Traffic generated by the site is also projected to have a very minor effect on area roadway
operations (Table 3.1‐12). LOS D or better roadway operations are projected under Year 2017
conditions along each of the study roadway segments.
Because most projected intersection and roadway LOS remain below specified LOS thresholds,
and because traffic volumes at the southbound approach to the SR 162/Larkin Road intersection
do not warrant signalization, projected traffic impacts on study area intersections and roadway
segments would be less than significant.
Mitigation Measures: No mitigation is required.
Headquarters Facilities Impact Analysis
The impact analyses described above under “General Plan Impact Analysis” address potential
impacts related to all aspects of the General Plan, including constructing and operating the
headquarters facilities. The following analysis addresses potential impacts specific to the
construction or operation of the headquarters facilities alone. These potential impacts are
different from (i.e., less than) the potential impacts described above that could be caused by
implementing the rest of the General Plan elements.
IMPACT
3.1-4
Increases in Peak-Hour and Daily Traffic Volumes Following Construction of the Headquarters
Facilities
Construction of the headquarters facilities would include the construction of an entry kiosk, which
would facilitate the collection of an entrance fee. Because no entrance fee is collected currently,
the number of visitors to Clay Pit SVRA is expected to decline during the time period between
construction of the headquarters facilities and construction of new OHV facilities. Therefore, there
would be no increase in traffic volumes following construction of the headquarters facilities, and
the project would cause no impact.
Mitigation Measures: No mitigation is required.
