3.10 Hazards and Hazardous Materials
Extensive nighttime lighting at Clay Pit SVRA could pose a hazard risk associated with nighttime
flights to and from the adjacent airport. However, because the SVRA would close at dusk, extensive
nighttime lighting for OHV activities would not be necessary. (See Impact 3.10‐4 below for a
discussion of nighttime lighting at the headquarters facilities.)
Because visitors to Clay Pit SVRA would remain only temporarily, facilities would meet ALUCP
height restrictions, General Plan guidelines incorporate measures to restrict concentrations of
people that would exceed ALUCP limits, and extensive nighttime lighting would not be required
for OHV activities, potential risks associated with the nearby airport would be less than
significant.
Mitigation Measures: No mitigation is required.
IMPACT
3.10-3
Potential Risk to People or Structures Caused by Wildland Fire
Because Clay Pit SVRA contains little vegetation, large bare areas, and only one small structure,
on‐site risks associated with wildfire are relatively low. However, activities occurring at the SVRA
could ignite a wildland fire (e.g., sparks from OHVs could ignite a fire in grassland) that could also
spread to adjacent areas. Likewise, activities taking place at the adjacent shooting range, airport,
and wildlife area could ignite a fire that could spread to the SVRA. Implementation of the General
Plan would generate an increase in the number of visitors to the SVRA, thus increasing the risk of
an accidental wildland fire, and would result in the construction of new structures, thus increasing
the risk of potential damage to structures as a result of wildland fire.
Implementation of the General Plan would result in an additional point of egress from the SVRA by
building a new entrance road while maintaining the existing entrance as a service entrance/exit.
This would improve evacuation opportunities in the event of a wildland fire. In addition, OM
Guideline 3.5 requires that OHMVR site management staff monitor and enforce the proper
handling and use of fuels, and the proper use of spark arrestors on OHVs.
Because risks associated with wildland fires are relatively low, egress to the SVRA would be
improved following implementation of the General Plan, and General Plan guidelines include
requirements that would reduce the risk of starting accidental wildland fires, risks associated with
wildland fires would be less than significant.
Mitigation Measures: No mitigation is required.
