Spruce Street Drainage Improvement Project (ENV15-0010)

Spruce Street Drainage Improvement Project (ENV15-0010)

The SSDIP includes drainage improvement activities to reduce standing water and sedimentation, and to allow increased flow along an approx. 1/2 mile section of earthen and concrete-lined drainage channel adjacent to Spruce Street. The proposed project would affect approx. 1.07 acres of jurisdictional water of the United States and state. of the 1.07 acres , 0.88 acre is within the earthen segment of the drainage channel. In order to off-set this impact, the project proposed mitigation in the form of on-site revegetation within the drainage channel, along with a 5-year monitoring and maintenance program to ensure the success of the revegetation area. Following a lengthy review of the City's required regulatory agency permits (i.e., 404 permit, 401 certification, and 1600 permit) it was recognized that one of the environmental permitting agencies would not accept the project's proposal for on-site mitigation without extensive revisions to the submitted permit material and preparation of additional reports, along without extensive revisions to the submitted permit materials and preparation of additional reports, along with obtaining a conservation easement over the subject revegetation area from the North County Transit District (NCTD). In order to stay within the timeline requirements of the various grants contributing to the funding of the project and to move forward with more certainty, an alternative mitigation measure to use existing off-site mitigation located within the City's Kit Carson Park has been supported by the agencies involved (RWQCB, Army Corps of Engineers, CDFW).
