Trail configurations shall be sited to avoid special-status plants and Viola pedunculata. In the event the City determines that trail construction cannot be accomplished without disturbance or mortality then trail construction would be abandoned and Icehouse Hill would remain closed for public uses, special-status plants shall be restored onsite in either the annual grassland or coastal scrub habitat located on Ice House Hill. Restoration would be at a 1:1 ratio consistent with typical CDFW requirements in areas that are to remain as post-development open space, as is Icehouse Hill. The 1:1 replacement ratio shall be met at the end of five years, and may therefore require initial plantings at a greater than 1:1 ratio, as determined by a qualified botantist. If feasible, special-status plants and/or seeds shall be salvaged from on-site plants and used for any replacement plantings.

To reduce impacts from off-trail use, and increased horse use in association with trail riding, trail head signage shall be required to educate the public regarding sensitive resources and restoration that would be affected by off- trail use. Mitigation areas shall be fenced or marked for three years.

Protected areas shall be marked in perpetuity. Trail use rules shall be developed prior to trail construction, and in addition to limiting use to identified trails, may include other requirements to limit the possibility that sensitive species would be impacted.

As part of trail construction, native grasses, and host plant species for special status butterflies shall be planted to enhance the existing habitat and assist in soil stabilization on Icehouse Hill. A planting palette shall be designed by a qualified botanist in coordination with the San Bruno Mountain Habitat Conservation Plan using plant species that are known to have high survival rates and are compatible with the flora and fauna of the region, as proven by successful restoration efforts on San Bruno Mountain.

To avoid indirect impacts to special status plant species that could occur if slope drainage or surface hydrology is modified as a result of trail construction Mitigation Measure 4.C1-g shall also be applied.

Prior to issuance of project approvals, and in coordination with state and federal permitting requirements, a five-year restoration mitigation and
