However, this additional information is insufficient to support a determination that the species currently has a moderate to high potential to occur on site, or to alter the conclusions or impact determinations presented in the Draft EIR.

Despite the uncertainties regarding this comment, Table 4.C-1 has been updated to include recent detection of this species.
[See page 5-192 for the original comment] Larval host plant for San Bruno elfin butterfly is Sedum spathulifolium, which has not been identified on Icehouse Hill. Sedum is a perennial forb species that would be identifiable if present within the Baylands during the various floristic survey periods undertaken for the Draft EIR. Because there are no sightings of this plant during any study period, the Draft EIR concluded that there was low potential for the San Bruno elfin butterfly within the Baylands Project area.
[See page 5-192 for the original comment] Existing feral animal populations at the site are part of the Existing Setting, and not an impact of Project Site development addressed in the Draft EIR. The Draft EIR does, however, analyze the Project site development-related impacts of feral cats and dogs as well as the introduction of household pets if residential development is ultimately permitted within the Baylands. Mitigation Measure 4.C-4b, page 4.C-57 and in Mitigation Measure 4.C-4c, page 4.C-57 both address impacts of household pets on area wildlife.
[See page 5-192 for the original comment] The Draft EIR recognizes impacts associated with increased foot traffic during construction and as a result of build-out. This is considered and addressed in the performance standards that establish wildlife migratory corridors. Buffers have been established around such corridors for the purpose of limiting wildlife-human interaction as a result of recreational uses. With respect to dog walking, the pet policy required by Mitigation Measure 4.C-4c would require dogs to be kept on a leash while outdoors or on passive use trails, except in dog parks revised to read as follows:
Mitigation Measure 4.C-4c: All development on the Baylands shall be required to have a no pets policy for construction workers. All development within the Baylands that includes a residential component shall also include a pet policy that requires residents to adhere to the measures of this policy to prevent impacts on wildlife from domestic animals. The policy shall become a part of the Covenants, Conditions, and Restrictions (CC&Rs) attached to each property deed for for-sale residential properties and enforced through the homeowners association or other entity specified in the CC&Rs, and made part of leases for residential rental properties and commercial leases within the Project
