IMPORTANT UPDATES TO MMSD CHAPTER 13
WHAT IS MMSD CHAPTER 13?
Chapter 13 is a set of rules and regulations that requires many sites within the District’s planning area to manage rain where it falls and reduce stormwater runoff.
MMSD CHAPTER 13 UPDATES
Previously, smaller sites that added less than a ½ acre of net new impervious area were not required to manage stormwater. But as of March 25, 2019, Chapter 13 has been repealed and recreated. According to MMSD, “This new regulation was created to help ensure that stormwater from smaller sites does not, over time, cause economic and environmental harm when it rains. Impacts from storms are forecasted to become increasingly challenging as our climate changes.”
There are several Green Infrastructure options to help meet these new requirements, including rain barrels and cisterns, rain gardens, native landscaping, stormwater trees, soil amendments, green roofs, porous pavement, bioswales and wetlands. Along with these more traditional Green Infrastructure strategies, there is a new strategy, the StormGUARDen, which boasts the smallest space requirement, and smallest maintenance cost of the above options. Not to mention the added luxury of providing you the ability to grow your own ADA accessible, above-ground garden, safe from local critters and crawlers.

WHY ARE THE NEW REGULATIONS IMPORTANT?
These new regulations are noteworthy, as they help to protect Milwaukee’s people and properties from flood risks, reducing possible overflows and basement backups, and safeguarding the watercourses. Furthermore, by managing water quantity and runoff, Milwaukee will also be taking steps towards improving water quality. By reducing pollutants such as pathogens, sediment, and heavy metals, the updates to Chapter 13 will help improve the water quality, ecology and biodiversity of waterways. Healthier Milwaukee waterways leads to improved public health and safety, along with greater opportunities for economic investments and overall usage of our waterways.
