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

3.1 Transportation and Traffic
Other considerations associated with special events include management of on‐site circulation
and parking areas. Special events such as motocross races typically result in a larger proportion of
visitors traveling in motor homes and/or towing large trailers. These vehicles may cause on‐site
parking and traffic issues if visitors park sporadically throughout the main activity areas.
Unmanaged parking could result in safety concerns for pedestrian traffic moving though the area
and could result in obstructed emergency access.
General Plan OM Goal 4 and associated Guidelines 4.2, 4.3, and 4.4 address these issues. A special
event permit from the OHMVR Division would be required for any event sponsor holding a special
event that would bring a certain density of visitors to Clay Pit SVRA. Each special event permit
would be individually reviewed by OHMVR Division staff. Through the permit review process,
traffic and parking control measures would be considered and required, as necessary, as
conditions of approval for the permit.
With parking and traffic control measures required as part of obtaining a special event permit,
potential traffic and parking impacts associated with a special event at Clay Pit SVRA would be
less than significant.
Mitigation Measures: No mitigation is required.
Year 2017 Plus Project Scenario
This subsection includes an analysis of projected traffic operations following implementation of
the General Plan, including construction and operation of the headquarters facilities, relative to
anticipated Year 2017 conditions. This time frame coincides with potential build‐out of the
Developed Use Area. Figures 3.1‐8 through 3.1‐11 display projected 2017 traffic volumes with and
without traffic associated with implementing the General Plan.
Projections of background traffic volumes within the study area for the 2017 planning horizon
were developed using existing traffic counts and forecast traffic volumes. Twenty‐year (i.e., 2030)
traffic forecasts were identified for the study area as discussed in the cumulative analysis (Chapter
4.0 of this DEIR), and Year 2017 conditions were projected by interpolating between existing
conditions and the 20‐year forecasts.
IMPACT

Increases to Peak-Hour and Daily Traffic Volumes under Year 2017 Plus Project Conditions
Projected intersection and roadway LOS are presented in Tables 3.1‐11 and 3.1‐12. Traffic
generated by implementing the General Plan is projected to have a very minor effect on operations
at each of the study intersections during either the weekday or Saturday peak hours (Table
3.1‐11). Satisfactory LOS C or better operations are projected to continue at all locations with the
exception of the southbound approach at the SR 162/Larkin Road intersection. Increased traffic at
