Eliminate/restrict bicyclists y
- Send bikes along Garden Hill
- Enforce bicycle speed limit
- Make bikes walk in tight areas
B ll d b i d k bik
- Bollards or barricades to keep bikes out
Keep cost down
- Patch and repair existing trail without widening trail
p g g
- Raise trail with fill rather than walls or deck
- Use funds to build a new trail to the new soccer park
- Staff meet with Susan Anawalt to discuss the option of
Staff meet with Susan Anawalt to discuss the option of detouring bicycles onto Garden Hill Drive and restricting their use on the trail.

Methodology & Strategy Natural Resource Permits
Section 1600 Streambed Alteration Agreement
(California Department of Fish and Game) ( p )
Section 404 Nationwide Permit
(Army Corps of Engineers)
Section 401 Water Quality Certification
(Regional Water Quality Control Board) Incidental Take Authorization impacts to federal Incidental Take Authorization impacts to federal and state listed species
SLIDE 31 Methodology & Strategy
Natural Resources - California Environmental Quality Act (CEQA) (CEQA)
CEQA process includes consideration of:
- Some species listed by the
California Endangered Species Act
- Species identified in the
State Fish and Game Code C pli ith CEQA i d f Compliance with CEQA required for:
- Streambed Alteration Agreement from CDF&G
W Q li C ifi i f RWQCB
- Water Quality Certification from RWQCB
