Clean Water Program Management with ArcGIS Online

Local agencies are required by the Regional Water Quality Control Board to comply with complex Clean Water program regulations including annual permits. With over 40 jurisdictions in Contra Costa and Alameda Counties, they joined forces to improve the information consistency and help local jurisdictions comply with the regulatory requirements by using GIS.

Psomas established a Clean Water Program GIS framework built on Esri’s ArcGIS Online technology. It helps manage common data and applications across the 40 agencies while providing standardization that achieves consistency with regulatory requirements, staff training, process updates, and reporting.

This evolving program includes a suite of web-based mapping applications that present an array of clean water related information such as land use, projects, and storm system characteristics. Adding to the mapping and reporting is field-computing tools used on iPads and smart phones for inlet inspections and other documentation of field observations. Activities and inspections are documented on standard forms and allow for the attachment of photographs.

The icing on the cake is that this system is designed for and used by staff who are experts in storm water compliance but not necessarily experts with GIS technology.
