Green Stormwater Infrastructure Code Audits: Updating Local Regulatory Structures for a Changing Climate

Abstract

The impacts of climate change, such as increasingly intense storms and more frequent floods, mean regulatory frameworks designed to manage stormwater runoff in previous decades may no longer be effective; codes and ordinances may inadvertently prohibit or inhibit the use of nature-based approaches to managing stormwater runoff. To adapt to current and projected climate change scenarios, local governments need updated regulatory frameworks that effectively manage stormwater runoff in a changed climate. Adapting local regulations to promote systematic use of green stormwater infrastructure (GSI) and other nature-based solutions is a key strategy that can contribute to the development of resilient, climate-adapted communities.

We worked with ten urban and rural municipalities across the Duluth area to conduct code audits and assist with designing and accomplishing community-specific GSI objectives, and we are currently expanding this project to include Lake and Cook Counties. These participating communities display a diverse array of geographical and demographic characteristics. However, after working with these communities’ technical staff and elected representatives to assess their regulatory structures and internal policies for areas that could be updated to prepare for increased heavy precipitation events, we have noted some important themes regarding needs, challenges, and opportunities that cut across the region. This poster will share what we are hearing from these communities and whether these themes point to emerging climate adaptation needs in Northeast Minnesota.
