Palm Springs MDP Line 41, Stage 3

Palm Springs MDP Line 41, Stage 3

NOTE: Document is a Subsequent Mitigated Negative Declaration. The proposed Palm Springs Master Drainage Plan (MDP) Line 41, Stage 3 project will consist of the construction and maintenance of an underground storm drain in Golf Club Drive, an earthen 6.7 acre detention basin and approximately 6,000 linear feet of an underground reinforced concrete pipe storm drain system ranging from 66 to 96 inches in diameter. The proposed storm drain facility will begin at the terminus of the existing Palm Springs MDP Line 41, Stage 2 inlet and generally extend in a westerly direction along East Palm Canyon Drive, Gene Autry Trail, Matthew Drive, Cherokee Way, and Santa Monica Drive. The proposed storm drain will extend westerly, for approximately 100 feet, past the intersection of Carmel Drive and Santa Monica Drive and terminate with a concrete lined inlet structure. The proposed project also includes the construction of lateral storm drains along Linden Drive and along the southerly extension of the unimproved Cherokee Way. These laterals will total approximately 1,000 feet in length and range in size from 36 to 48 inches in diameter. Additional capacity will also be provided at Golf Club Drive by increasing the size of the existing storm drain under Golf Club Drive and reconstructing the concrete lined inlet structure just to the north of East Palm Canyon Drive. The project will be designed to convey the estimated 100-year flow rate. The proposed project was initially approved in April 2006. However, this Subsequent MND was prepared in response to new information regarding potential impacts to biological resources (i.e., Casey's June beetle). The original MND adequately addressed all impacts except the Casey's June beetle. Therefore, this Subsequent MND only addresses potential impacts to the Casey's June beetle.
