Project: Correcting a long-standing water quality pollution problem at Morro Bay MPAs and National Estuary

Description: Correct stormwater-related water quality problems at the Morro Bay State Park Marina Parking Lot. During storm events, water quality frequently falls below standards and the bay is listed for multiple pollutants. The project will address stormwater pollution through stormwater diversion and allowing for percolation and removal of pollutants through biofiltration.

Reference Number: 0540P01202

Implemented By: Morro Bay Estuary Program

Objective: The project includes a planning phase to complete engineering designs for the project, as well as an implementation phase to complete the infrastructure elements. During the planning phase, additional site surveys will be used to inform the development of project designs that will incorporate topographic and geotechnical constraints. The conceptual design involves re-grading the parking lot to direct stormwater to a central drain and then pumping the water to a biofiltration site on the east side of Lower State Park Road, in an area more conducive to infiltration. The parking lot will be re-paved during the project, improving usability and reducing sediment inputs to the bay from the portion that is currently unpaved. The final project will also include monitoring to track water quality and outreach to share information about the project and stormwater with visitors. Outreach will target both visitors to the site and to the greater Morro Bay State Park.
