Wisconsin Standards Oversight Council (SOC) and Wisconsin Department of Natural Resources (DNR) are seeking public comment on two draft DNR technical standards related to storm water facilities with no permanent pool.

One standard focuses on vegetated dry detention and another addresses dry basins with additional treatment elements for both total suspended solid (TSS) and phosphorus (P) reduction.

These standards provide criteria for the design, installation and maintenance for the following practices:

Technical Standard 1011 Vegetated Dry Detention Pond provides a limited but quantifiable water quality benefit without a permanent pool.

Technical Standard 1012 Storm Water Sand Filter System provides for additional treatment elements to maximize and quantify TSS reduction, with optional enhancements to address P removal.

These standards are being created following the Full Process outlined in the Wisconsin Standard Oversight Council (SOC) Handbook. Over the past two years, a technical work team met numerous times to share their expertise and experiences, identify the goals and issues related to dry storm water detention, learn from researchers and experts in the field, and consider input through expert and public review. The project goals and progress are documented on the SOC team website.

How to submit comments:

  • Review the updated drafts of Technical Standard 1011 – Vegetated Dry Detention Pond and/or the draft of Technical Standard 1012 – Storm Water Sand Filter System.
  • Submit comments via email to soc@wisconsinlandwater.org by midnight on May 9th 2025.
    • Keep comments specific and directly related to the two standards;
    • Insert your comments into the Adobe pdf document or otherwise indicate the line number(s) page(s) to which each of your comments refer;
    • If you have general comments applicable to the entire standard, please note them as such;
    • Lastly, given that there are two standards available for public review, please be clear regarding which standard your feedback is in reference to.

After the review period is concluded, all comments will be considered by the DNR and the SOC team for these technical standards Revisions may be made to the document and the final updated technical standard will be published and made publicly available.
