NEW Stormwater Engineering Design Standards

​​​​​​​​​​​​​​​​​​​​​​​​​​​​Get updates when this information changes

The Oakland County Water Resources Commissioner's office (WRC) is happy to announce Oakland County's new stormwater design standards for developments under WRC's jurisdiction. To develop these standards, this office facilitated more than 40 regional meetings with Oakland, Livingston, Macomb, and Wayne Counties and coordinated with numerous Oakland County communities, along with stakeholders, for their input. The WRC would like to extend special thanks to the dedicated stormwater experts from the four counties who continue to participate in this very successful and ongoing regional stormwater collaboration.

Many communities will receive a new MS4 permit requiring the adoption of new stormwater engineering design standards to meet water quality requirements. The goal is for communities to adopt our state-approved regional standards to meet the requirements. We are confident that communities will appreciate how straightforward these standards are and adopt them. Changes to the standards to meet local needs are expected, but these changes may require approval from the Department of Environment, Great Lakes and Energy (EGLE).

Please be assured that this office remains committed to providing ongoing guidance to assist all stormwater stakeholders in Oakland County in understanding and implementing these new standards and all relevant information will be continually updated on this page. Sign up at the link on the top of this page to be alerted to any available updates. All recorded meetings and questions and answer sessions will also be posted on this page.

 Standard Objectives

​These new standards accomplish the following objectives:

1. Improve surface water quality as well as channel and stormwater infrastructure protection.

2. Require volume-reducing, low-impact development measures and protect natural features.

3. Control both the quality and quantity of stormwater runoff.

4. Promote sustainable regional stormwater management practices.

5. Long-term operation and maintenance of stormwater systems.

6. Consistent and straightforward regional standards that meet federal and state permit requirements.

7. Promote consistent stormwater reporting, tracking, and mapping.

8. Recognize that similar standards are anticipated for combined sewer areas.
