Document Description
CDFW is intending to execute a Lake and Streambed Alteration Agreement pursuant to Section 1602 of the Fish and Game Code (# EPIMS-SDO-15182-R5) to the project applicant, City of San Diego. The project is described as a 2-phase project. Phase 1 will replace 16 existing storm drain systems (SDs) from adjacent streets that outfall into Maple Canyon and construct a new SD within Maple Street, and Phase 2 will restore and expand the channel to establish streambed and riparian habitats along the canyon floor. For Phase 2, the existing creek is to be completely regraded to stabilize the streambed and banks, to prevent further erosion, and to restore native habitat to all areas being graded. The streambed will be widened, and 23 4-ft drop structures will be added to reduce the gradient between the structures and slow water velocities to stop erosion. Boulders will be placed at the base of the drop structures to dissipate the energy of the water. The streambed is to be planted with mostly short, wetland or facultative wetland, annuals and perennial shrubs. The banks will be planted with streamside-adapted species. Upper bank and any floodplain areas will support a mixture of bottomland annuals, perennials, shrubs, and riparian trees.
