Jurupa Valley NPDES Compliance

The City of Jurupa Valley, California, was allotted four weeks to complete a mandatory clean-up of at least 80% of its 1,039 stormwater inlets. This activity was mandated to meet guidelines established by the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) permit program.

To accomplish this, the City retained HR Green to develop a comprehensive solution allowing for the efficient collection of inlet maintenance field data, data, tracking project progress, and analyzing data trends for improved long-term asset management. HR Green configured the City’s GIS database to work with an app, interfacing with Collector for ArcGIS and Operations Dashboard. In addition, HR Green developed a map to help field personnel prioritize locations and collect data quicker, more efficiently, and consistently.

Within four weeks, two 2-person field crews were able to clean 869 inlets – 84% of those slated for maintenance, thereby exceeding the NPDES requirement. In addition to exceeding the NPDES requirement, HR Green was able to work with the City to establish a GIS stormwater inlet database with critical interface applications for future maintenance management and sound decision-making associated with the City’s stormwater system. This GIS System shows each inlet’s maintenance history, how much total material had been removed, and what type of material removed was most abundant.
