Title
Substitute resolution expressing support for the City of Milwaukee’s Framework for Green Infrastructure Plan.
Analysis
This resolution expresses support for the City of Milwaukee’s Framework for Green Infrastructure Plan, including support for the adoption of higher regional thresholds for the use of green infrastructure to reduce stormwater runoff.
Body
Whereas, During wet-weather events, large volumes of stormwater enter the local sewerage system, increasing the volume of wastewater that the Milwaukee Metropolitan Sewerage District (MMSD) must convey and treat; and
Whereas, During wet-weather events, stormwater can overwhelm the local sewerage system, causing combined sanitary and stormwater flows to back up through floor drains and flood basements of homes and businesses; and
Whereas, Green infrastructure, which refers to any combination of landscaping, facilities or equipment that captures rain, at or near the site where it falls, by infiltration into the soil, evapotranspiration by plants, or storage for beneficial re-use, reduces the volume of stormwater in the sewerage system, thereby reducing water treatment needs, improving water quality, reducing grey (artificial) stormwater infrastructure needs and reducing flooding; and
Whereas, Green infrastructure may include rain gardens, constructed wetlands, green and blue roofs, bioswales, landscaping with deeply rooted plants, rain barrels and cisterns, trees, soil amendments, permeable surfacing and the removal of water-infiltration impeding structures or pavements; and
Whereas, Beyond reducing stormwater runoff, utilization of green infrastructure confers a host of co-benefits, including:
1. Increasing available water supplies.
2. Increasing groundwater recharge.
3. Reducing salt use.
4. Reducing energy use.
5. Improving air quality.
6. Reducing atmospheric carbon dioxide.
7. Reducing urban heat is...
