Municipal stormwater permittees in Orange County (OC) are undertaking an effort to standardize and improve their stormwater BMP inventories and build tools to manage and analyze these assets. To support these efforts the OC permittees are building an open-source web application – OC Stormwater Tools. This application is designed to facilitate collaboration between permittees for several purposes such as developing high-resolution inventories of BMP asset datasets, performing inspections and maintenance tracking, delineating drainage area, surveying land use conditions related to California Trash Provisions, and quantifying BMP pollutant load reduction performance. This platform provides dashboards, data summaries, and maps to help prioritize capital and O&M expenditures while streamlining regulatory reporting. With the application, the Permittees are working toward a vision where valuable datasets grow over time, decision-making is supported by the underlying data, and reporting is simplified. The application is open source via GNU Affero General Public License and can be freely redistributed and/or modified under the terms of the open source license. As a result, the open source nature of the tool creates opportunities to partner with others to expand and benefit from this project.
