Stormwater Management Permit
Development projects that are disturbing >10,000 square feet of soil or
modifications to sites that have existing stormwater management
requirements will require stormwater management in accordance with Chapter 37 of the Madison General Ordinances. Separate permits for erosion control and stormwater management are required for projects permitted by City Engineering.
- A general overview of stormwater management design requirements is available on our Development Services Center website.

Stormwater Management Annual Inspection and Certification
Properties that have a stormwater management permit as a condition of their approval require an annual inspection and certification to be
submitted to City Engineering. Inspections should be done every calendar year, with reports being submitted by June 1 of the following year. Submissions shall be emailed to City Stormwater Management staff or Engineer@cityofmadison.com.
Standard Forms:
- Stormwater Management Annual Maintenance Certification
- Stormwater BMP Inspection Form - Storm Water Structures
MGO 37.09(7) Annual Stormwater Management Report. Each applicant who is granted a stormwater management permit, and who has signed and recorded the required maintenance agreement, shall submit to the City Engineer an annual report on the condition of the site's stormwater management devices.
The annual report shall include the following:
(a) Documentation of the completion of the required annual maintenance, including copies of receipts (actual prices paid need not be reported) from agents hired to perform the work and the date the work was completed;
(b) Photos of the management device at the time of inspection. This shall include photos of existing conditions and photos after the completion of any required maintenance.
This report shall be submitted by June 1 of each year following closure of the Stormwater Management Permit required under Sec. 37.09(6). The annual report shall be completed and sealed by a Professional Engineer currently licensed in the State of Wisconsin, on forms provided by the City Engineer. The requirement that the annual report be sealed by a Professional Engineer may be omitted in the case of a stormwater management plan consisting solely of storm sewer inlet filters, catchbasin sumps, or underground tanks, provided that the applicant can provide the appropriate documentation and dated photos as outlined in Secs. 37.09(7)(a) and (b). For sites with more extensive stormwater management systems, the Administrative Authority may allow other appropriately credentialed professionals to complete this work at their discretion.
For sites that have a stormwater management device (or devices) that require a topographic survey every three years, this survey requirement may be satisfied through the submittal of adequate photographic documentation. The acceptance of date stamped photographs in lieu of a topographic survey is at the discretion of the Administrative Authority. The topographic survey requirement waiver may only be applied to qualifying detention or infiltration basins.
For sites that have a stormwater management device (or devices) that infiltrate stormwater, the inspection shall be completed between 24-72 hours after a rainfall event > ½ inch to ensure it is draining down appropriately. Copy of a weather report with rainfall amount shall be included in the inspection report.
