DevStd ECO-EGV-6B: Native Woodland Buffer Areas: Within urban areas and existing developed rural neighborhoods, native woodlands shall be preserved by providing a minimum 25-foot buffer around the respective habitat area. Within areas zoned Mountainous-GOL, the buffer around native woodlands will be 50 feet (page 158). DevStd ECO-EGV-6C: Native Grassland and Coastal Sage Scrub Buffer Areas: Native grasslands and coastal sage scrub shall be preserved by providing a minimum 25-foot buffer vegetated with native species and by placing the project outside of the buffer rather than in or through the middle of the habitat area (page 158). DevStd ECO-EGV-6E: (INLAND) Any construction, grading or development within 200 feet of known or historic butterfly roosts shall be prohibited during the months between November 1 and April 1 (page 158). Policy ECO-EGV-6.3: Riparian vegetation shall be protected and shall not be removed except where clearing is necessary for the maintenance of free flowing channel conditions, the removal of invasive exotic species, the provision of essential public services, or where protection would preclude the reasonable use of a parcel (page 160). Policy GEO-EGV-2.2: No development shall be allowed on slopes of 30 percent or greater. Avoid ground disturbances and development on slopes of 20 percent or greater unless such avoidance would preclude reasonable use of the parcel (page 167).
