Currently, runoff from the boat wash area in Morro Bay is routed via a valley gutter to a storm drain inlet that outfalls to the Bay. The concept design option shows modification of the existing landscape strip adjacent to the inlet into a biofiltration Stormwater Control Measure (SCM).
Runoff would be routed into the biofiltration SCM and infiltrated through bioretention soil media with treated runoff exiting the SCM via an underdrain to the existing piped stormwater conveyance system. The existing inlet also receives stormwater runoff from the north. In addition to stormwater quality control, the biofiltration design provides urban greening improvements on the waterfront.
