Optimizing Best Management Practices and Sustainability with an Integrated Drainage Plan – County of San Diego, California
The purpose of the Integrated Drainage Plan is to identify opportunities for water quality and flood control improvements specific to northern Winter Gardens Boulevard, located in the unincorporated community of Lakeside in San Diego County. The project serves as a pilot comprehensive drainage plan that allows the County to plan water quality projects in a manner than optimizes sustainable water quality benefits, costs, and provides additional multi-benefits where feasible. The plan initially identified 14 potential project locations within the 925-acre Winter Gardens watershed study area. Through a series of meetings and workshops, the project team evaluated the projects both individually and in series to select the collection of projects that worked together to achieve water quality compliance goals while minimizing costs and maximizing multi-benefits. While this effort presented a single Preferred Scenario, the information obtained in the process can be used for future projects in the Winter Gardens drainage area, and the process can be performed for other watersheds. At this time, the County is coordinating with key stakeholders to solidify implementation options and explore recreation benefits.
Pilot projects are commonly used by municipalities to help determine the best approach to meet their objectives. Municipalities are often progressing with a focus on multiple objectives in their search for sustainable projects for their areas.
This technical presentation will discuss the tools, ideas, and concepts considered for this project, as well as the challenges and lessons learned. The audience member will have a better understanding of the formulation of multi-benefit projects, specifically for both water quality and flood control.
