Faced with meeting sediment removal goals outlined by Water Quality Improvement Plans (WQIPs), the City of San Diego and its engineering firm partners were tasked with developing an Optimized Implementation Plan (OIP) for the City's Catch Basin Cleaning and Street Sweeping programs. This adaptive management plan blended mobile GIS technology with holistic prioritization strategies to achieve costs savings, increased crew productivity, and improved water quality city-wide. Historic sediment removal trends and parallels between the two programs were identified and used to develop prioritization strategies. Mobile GIS technology streamlined cleanings and allowed management to assign work based on the developed prioritization strategies. After one year of implementation, the OIP resulted in an 82 percent increase in the volume of sediment removed and a reduction of 9,090 cleanings needed to meet WQIP goals. As the plan evolves, additional long-term sediment deposition trends and optimization opportunities will become apparent, cementing program sustainability and effectiveness.
