Proposed Stormwater and Residential Lot Coverage Regulations

One of the most common topics mentioned during public engagement for the comprehensive plan regarding residential neighborhoods was stormwater. Many participants referenced a need to reduce runoff impacts of new development and redevelopment of properties in light of more frequent and intense storm events and patterns of larger homes. Additionally, there was a desire for city regulations to support or encourage use of more sustainable development design. As a result, a key result was included in the implementation matrix:

Develop a coverage reduction program that identifies innovative ways to reduce the amount of impervious coverage and promotes green infrastructure.

Additional key results that are addressed partially by the proposed regulation include:

  1. Develop a partnership with MSD to coordinate updates to stormwater management regulations and proactive approaches to regional watershed management.
  2. Establish appropriate infill development standards for building form and materials.
  3. Our neighborhood development patterns embody sustainable principles and seek to minimize impacts on the natural environment and plan for future resilience.
  4. Prioritize greenspace, trees, and sustainability in residential neighborhoods to retain existing character.
  5. Prioritize rain gardens, native plants, and other sustainable elements in our public spaces.

A public hearing is scheduled for the Plan Commission meeting on December 1, 2025, at 5:30pm. A draft of the proposed regulations has been added under the documents folder of this page for review prior to the meeting. During the meeting, staff will present an overview of the proposed changes, the Plan Commission will discuss, and the public will be allowed to make comments.
