The Vegetated Swale Technical Standard 1005 (previously “Vegetated Infiltration Swale Interim Technical Standard 1005”) has been updated. The draft was posted for public review, and the technical team revised the draft to address public comments. The document provides technical specifications for the design, modeling, construction, implementation, and maintenance of new vegetated swales for purposes of compliance with storm water post-construction performance standards in ch. NR 151, Wis. Adm. Code.

Thank you to the Standards Oversight Council team members who coordinated for over one year to complete this update, and to the dozens of people who provided comments during the initial and broad review periods that helped refine this document.

The technical standard is also available at the DNR’s storm water post-construction technical standards webpage.
