A segment of underground storm water drainpipe was designed but never installed between two existing (capped) drainpipes under Bobolink Drive. This substandard drainage causes street flooding during significant rain events, and also creates malodorous odors from stagnant standing water and increased vector habitats. The proposed project would install approximately 2,000 linear feet of 36 to 54-inch diameter reinforced concrete pipe (RCP) within the existing street to connect the capped storm water drainpipes. By adding a minor amount of RCP, this project would increase the efficiency of the existing storm drain system in this portion of Vista to normal city standards.
The proposed project is exempt under State CEQA Guidelines Section 15301 Existing Facilities, which is a Class 1 exemption. Class 1 exemptions, "consists of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of use beyond that existing at the time of the lead agency's determination." The proposed project consists of adding a minor amount of RCP to increase the efficiency of the existing sub-standard storm drain system in a portion of Vista to normal city standards. This involves a negligible expansion of the existing use that would significantly reduce flooding, malodorous odors, and vector habitats in the project area.
