The property is at 4987 Brown Bear Lane, south of State Route 49, approximately 0.3 miles northwest of the intersection of State Route 49 and State Route 140. The project will be built in two phases. Phase 1 will involve construction of the Brown Bear Hotel and Yosemite Conference Center on four parcels totaling 11.2 acres. Phase 1 will involve a zone change of a 7.02-acre parcel and a 0.39-acre parcel from residential to commercial. Phase 2 will involve construction of residential housing on two parcels totaling 6.76 acres. The purpose of the project is to increase capacity to provide lodging, meeting space, and residential housing in Mariposa. To evaluate whether the project may affect biological resources under California Environmental Quality Act (CEQA) purview, we (1) obtained lists of special-status species from the California Department of Fish and Wildlife, the United States Fish and Wildlife Service, and the California Native Plant Society; (2) reviewed other relevant background information such as aerial images and topographic maps; and (3) conducted a field reconnaissance survey of the project site. This biological resource evaluation summarizes existing biological conditions on the project site, the potential for special-status species and regulated habitats to occur on or near the project site, the potential effects of the project on biological resources and regulated habitats, and measures to reduce those potential effects to a less-than-significant level under CEQA. We concluded the project could impact three non-listed, special-status wildlife species and nesting migratory birds, but effects can be reduced to less-than-significant levels with mitigation. We also concluded the project could affect one regulated habitat.
