Pond 2, and in the area of the proposed detention basin. Potential salamander breeding habitat is present offsite in a stock pond 1.1 miles west of the site, and in three stock ponds located between 0.7 and 1.3 miles east of the site. The proposed project would not cause disturbance or removal of breeding habitat, but loss of adjacent upland habitat areas within 1,000 feet of suitable breeding habitat that is favored by this species. Other possible impacts include reduction in the species capability to travel to potential offsite breeding habitat due to the development of upland areas and drainages, as well as reduction in water quality and aquatic habitat due to increased sedimentation and input of other substances in streams from runoff. ^ California Red-legged Frog California red-legged frog was observed adjacent to Pond 2 in October, 2004. Potential breeding habitat is present offsite in a stock pond 1.1 miles west of the site and in three stock ponds located between 0.7 and 1.3 miles east of the site. Site preparation and construction activities could result in a loss of upland habitat or direct mortality of this species. Other possible impacts include reduction in the species capability to travel to potential offsite breeding habitat due to the development of upland areas and drainages, as well as reduction in water quality and aquatic habitat due to increased sedimentation and input of other substances in streams from runoff. ^ Callippe Silverspot Butterfly Based on the surveys conducted on the site to date, it has been determined that the project site contains Viola pedunculata, the larval host plat for the Callippe silverspot butterfly (Speyeria callippe callippe) and other subspecies of the species Speyeria callippe, and that butterflies which need this plant for part of their life cycles may occur on various portions of the project site. Based on these initial observations, it may be that Speyeria callippe callippe occurs on the site but, due to the similarities between Speyeria callippe callippe and other subspecies or hybrids, a positive identification must still be made. If Speyeria callippe callippe are considered to be present and their habitat area impacted by the development, then mitigation measures will be identified and implemented subject to the review and approval by the USFWS. This matter will be resolved before the recordation of the first final subdivision map for this development. ^ Nesting Raptors Active raptor nests are protected. Red-tailed hawks, Cooper's hawks, sharp- shinned hawks, and golden eagles could potentially establish nests within the project site prior to construction. The removal or disturbance of a nest during construction resulting in abandonment of eggs or young, or direct mortality, would constitute a significant impact. PUD-33 Page 30 of 59 June 13, 2007
