ECSWM Requirements

Permit Process Applicability

Erosion Control and Stormwater Management (ECSWM) Permits include a plan and checklist that describes the steps a developer, contractor, or landowner will take to prevent soil erosion on disturbed sites.  Some projects will also require plans to permanently manage runoff from the site after all construction is complete.

ECSWM Performance Standards Update - Effective April 1, 2015

Please note that the Natural Resources Conservation Service (NRCS) has recently adopted the current NOAA Atlas 14 rainfall depths for the 24-hour storm events, along with new rainfall distributions for Wisconsin. All ECSWM permit applications submitted after April 1, 2015 need to be prepared using these updated depths along with the MSE4 rainfall distribution (which is required throughout Dane County).  HydroCAD users can download this distribution at:

 Here's a summary of the NOAA Atlas 14 rainfall depths for the following 24-hour storm events:
1-year = 2.49" (was 2.5")
2-year = 2.84" (was 2.9")
10-year = 4.09" (was 4.2")
100-year = 6.66" (was 6.0")

These changes will be incorporated into Chapter 30, Article II of Fitchburg's Municipal Code in 2017 as staff monitors any additional changes to ECSWM requirements anticipated to be adopted by Dane County and State of Wisconsin.

Private Stormwater Facility Maintenance Agreements and Reports

Properties will need to have a Stormwater Maintenance Agreement (pdf) (MS Word) recorded at the Dane County Register of Deeds for any private stormwater facilities installed such as rain gardens, storm pipes, swales, pervious pavement, and detention ponds. A legal description, map and list of measures being taken shall be included with the Maintenance Agreement as Exhibit A (pdf) (MS Word).  The property owner will need to submit Inspection and Maintenance Reports to the Public Works Department through PermiTrack


The city requires all ECSWM permittees to report erosion control inspections through PermiTrackESC, which is a we-based system allowing active construction sites to be viewed easily on a map. The map provides markers showing all currently active construction sites in the city that require an ECSWM permit.  Fitchburg has been using this system since January 1, 2014 s
howing all current construction sites in Madison. When you click on the map “push pin”, it will bring up information on the site and allow you to view erosion control inspections for the site and to provide a comment on the condition of the site. If you submit a comment it will be sent to City Engineering and to the permit holder for the site.  Go to: Active Construction Sites in Fitchburg
