CSD Demonstrates Storm Water Compliance Using GIS

Cosumnes Community Services District (CSD) needed to create an inventory of drainage inlets to meet California State Water Control Board storm sewer system requirements.

Interwest acquired data, created map products, and a custom webpage to view and edit the data:

• Data exports acquired from the City of Elk Grove
• Web map of inlets, pipelines, and outfalls in or near the CSD’s parks and fire stations
• Field inspections to add inlets within the District’s parks
• Custom webpage to display the inlet details and images

The data creation process included starting with the infrastructure provided by the City of Elk Grove, removing inlets, pipeline and outfalls that were not connected to CSD’s parks or firestation, adding new inlets that were within CSD’s properties, and mapping them to their appropriate outfall. Field inspections were conducted using Collector for ArcGIS to add inlets and their related details and photos.

The District is able to demonstrate the flow of storm water from inlet to outfall to the California State Water Control Board for each of their properties, track inspection date, watershed area, ownership information and images to assist with state requirements as well as maintenance efforts. 

The webpage allows staff to edit live data from the rest end point of the hosted feature class; any changes to the inlets on the webpage are available immediately on the map in ArcGIS Online or Collector for ArcGIS.
