Project Description
RICK prepared multiple GIS-based Master Drainage Plans (MDPs) and corresponding Storm Water Quality Master Plans (SWQMPs) for the County of San Diego for the following special drainage areas:
- SDA 1 – Spring Valley, CA (12 square miles)
- SDA 7 – Alpine, CA (19 square miles)
- SDA 8 – Ramona, CA (120 square miles)
- SDA 10 – North County Metro Area, CA (88 square miles)
Each MDP included detailed drainage basin delineations, flow-line information, and watershed information that was prepared in a specific convention required for GIS processing. The hydrologic base, using GIS current soil, land use, and vegetation data, was calculated. The data was imported into AES-SIMS to prepare the detailed hydrologic and hydraulic calculations required for design of the drainage improvements for the areas.
GIS applications combined with AES-SIMS created interactive MDPs for the County of San Diego. The interactive MDPs provided 100-year peak discharges, proposed future or and/replacement master plan facility sizes, and calculated approximate replacement costs for future development.
