ALAMEDA WHIPSNAKE Sample Clauses

ALAMEDA WHIPSNAKE. All whipsnake traps have been removed from the project site. Non-mitigation related construction at the project site continues to be limited to work within the developed residential areas, which are surrounded by the completed golf course. Monitoring of mitigation habitat for whipsnakes (i.e., grassland, rock outcrops and scrub enhancement) will continue as required. No whipsnakes were observed by LSA biologists or Stonebrae staff in the golf course or open space areas in 2016.

ALAMEDA WHIPSNAKE. The four dig sites do not overlap with HCP-modeled habitat for Alameda whipsnake, a federal and state-listed species and an HCP no-take species. The closest areas mapped as Alameda whipsnake core habitat, perimeter habitat, or movement habitat are more than 3 miles to the west. Based on the lack of core habitat (low-growing shrub communities) in proximity to the dig sites (more than 3 miles), Alameda whipsnake is not expected to occur within the designated work areas and access routes (Figures 3a, 3b, 3c, and 3d). No impacts to this species are anticipated. Based on HCP modeled habitat, the four dig sites are located within suitable burrowing habitat. Grassland at all of the four dig sites provides suitable nesting and wintering sites for burrowing owls and owls have been documented throughout the Xxxxx Xxxxx Regional Preserve (California Department of Fish and Wildlife 2017). Ground squirrel xxxxxxx that could be used by burrowing owls are present within and adjacent to proposed work area and access routes for each of the four dig sites. During the February 28, 2017 reconnaissance surveys, a burrowing owl was observed using a xxxxxx located 420 feet west of Dig Site 11. To avoid and minimize impacts on nesting burrowing owls, Shell Pipeline or its contractor will implement HCP species-level conservation measures prior to and during construction, as applicable. Based on HCP modeled habitat, the four dig sites are located within suitable golden eagle habitat. The closest documented eagle nests are located approximately 0.65 mile west (CNDDB occurrence #147) and 0.75 mile southwest (CNDDB occurrence #71) of the proposed work areas and access routes. The closest potential habitat to proposed work areas and access routes is present in oak woodlands approximately 0.4 miles to the west. To avoid and minimize potential impacts on nesting golden eagles, Shell Pipeline or its contractor will implement HCP species- level conservation measures prior to and during construction, as applicable. Grassland within and adjacent to designated work areas and access routes at the four dig sites provides ground- nesting habitat for migratory birds. Vegetation removal and disturbance that occurs during the breeding season (generally March through August) could result in the removal or destruction of nest with eggs or young. Disturbances that result in mortality of adults, loss of fertile eggs or nestlings, or other events that lead to nest abandonment are prohibited under the fe...
