Alberhill System Project

The project is located in unincorporated Riverside County, California, in addition to within the cities of Lake Elsinore, Wildomar, and Menifee. The project’s northern extent is located north of the Interstate 15/Temescal Canyon Road intersection in Lake Elsinore, continues southeast, and terminates north of the intersection of Newport Road/Murrieta Road in Menifee. The project’s approximate center coordinate and central Assessor’s Parcel Number are Latitude 33.705427, Longitude 117.372047, and 389-100-030, respectively. Project Description: This proposed project involves: the construction of the new 1,120 megavolt-ampere, 500/115 kilovolt (kV) Alberhill Substation by the Valley South 115 kV System; the construction of two new 500 kV transmission line segments to connect the proposed Alberhill Substation to Southern California Edison's existing Serrano-Valley 500 kV Transmission Line; the construction of a new 115 kV subtransmission line approximately three miles in length; modifications to four existing 115 kV subtransmission lines between five existing 115/12 kV substations; and telecommunication improvements to connect the new facilities to Southern California Edison’s telecommunication network. The Project will result in impacts to 168.96 acres of Crotch’s bumble bee (Bombus crotchii) habitat including temporary impacts to 113.95 acres; the Project will permanently remove 55.01 acres of Crotch’s bumble bee habitat. The project is expected to result in incidental take of Crotch’s bumble bee, which is designated as a candidate endangered species under the California Endangered Species Act. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
