RE: Municipal Code Chapter 14: Post-Construction Storm Water Management
Ordinance Update Analysis
City Engineering Division Staff, in conjunction with Brown and Caldwell, are currently
evaluating the post-construction pollution control requirements within Municipal Code Chapter
14. The need for this evaluation was originally identified as part of the City of Oshkosh Stormwater
Quality Management Plan, November 2022 (Citywide SWMP), which was approved by the
Common Council (Council) on December 13, 2022. This Citywide SWMP was completed in
response to the completion of the Total Maximum Daily Loads for Total Phosphorus and Total
Suspended Solids Upper Fox and Wolf Basins, February 2020 (Upper Fox and Wolf TMDL) which
was prepared by the Wisconsin Department of Natural Resources (WDNR) and approved by the
Environmental Protection Agency (EPA).
City Staff held a workshop with Council on April 29, 2025 to discuss the history of the City of
Oshkosh’s Stormwater Requirements and the analysis for updating the post-construction
numeric standards of Municipal Code Chapter 14. The workshop was recorded by Oshkosh
Media and can be found using the following link:

Staff is looking for a recommendation from the Sustainability Advisory Board to move forward
with one (1) of the five (5) Scenarios presented to Council. In addition to the Sustainability
Advisory Board, we will be giving this information to Plan Commission for a similar
recommendation. After Sustainability Advisory Board and Plan Commission give their
recommendations, we will work to make the changes to Municipal Code Chapter 14 and bring
them forward for full approval by Council in late fall 2025 for implementation on January 1, 2026.
