The City of National City led efforts to enhance the Paradise Creek Watershed by reducing flood risk, improving water quality, and improving the community’s quality of life by adding parks, green streets, and trails with educational signage. This project removed 16 properties from the FEMA 100-year Special Flood Hazard Area (SFHA), treats 30 acre-feet per year (AFY) of stormwater, and infiltrates 4.6 AFY of stormwater. The project included planning, grant writing, design, and construction. $5.3M in grant funding was successfully obtained for the project through the multi-benefits provided and disadvantaged community benefits. The City partnered with several NGOs to help with the creek’s future maintenance, including developing an agreement with the City of San Diego’s Transportation and Storm Water Department on long-term creek operations. After this session, participants will be able to
• Communicate the benefits and challenges of designing, building and maintaining an urban street tree capy;
• Justify the importance soil (growing media) to achieve tree growth to maturity and considerations for use of soil cells to achieve required soil volume;
• Integrate stormwater management approaches to the design of continuous soil trenches.
