Stormwater Management
Milwaukee's stormwater management is governed by Chapter 120 of the Milwaukee Code of Ordinances and enforced in coordination with the Milwaukee Metropolitan Sewerage District (MMSD).

MMSD's Regional Green Infrastructure Plan promotes bioswales, rain gardens, permeable pavement, and green roofs. Milwaukee has invested heavily in green infrastructure to reduce combined sewer overflows into Lake Michigan.
