Maps & Permit Data Active Stormwater Permits Map This interactive map indicates the locations of current stormwater permitees. Be sure to check the legend to see which color dots represent which kind of permits. Note: Construction Stormwater Permits are not on this map. How to Find Permit Data The following are provided for informational purposes only and are updated periodically. Check the permit folder for current information on a project (modifications, rescissions, etc.) NPDES Construction Permit List as of 12/31/2021 at 11:59 pm Permit records are available in the Construction Stormwater COCs folder of the Laserfiche repository. NPDES Industrial Active Permit List as of 1/1/2022 Permit records are available in the General Permits and Individual Permits folders of the Laserfiche repository. Post-Construction Active Permit List as of 1/1/2022 Some of the permit records (about 20%) are available in the SW Permits folder of the Laserfiche repository. The estimated completion date for scanning Post-Construction permit files is Dec 2022. Post-Construction Stormwater Map This viewer is only a tool to help in making final determinations about your responsibilities for permit coverage. Please read the information below about using the results of this map viewer. Please note that if that there are a number of areas currently indicated as "No Program Required" that are subject to special watershed strategies that require stormwater permit coverage. You can read about this at the Special Designations Descriptions web page. Information About Map Results Map Updates and Corrections For assistance with the interactive map, please contact Bethany Georgoulias. Reference Maps for Determining Permitting Requirements Impaired Waters & TMDL Map Waterbody Classification Map Watershed Drainage Area Map HQW, ORW and WS Reclassifications There may be waterbodies that have either recently been reclassified as High Quality Waters, Outstanding Resource Waters or Water Supply Watershed, or are pending reclassification. These areas are not reflected in the current interactive map, but they may now be subject to local or state stormwater program requirements.
