Triple-I Weblog | Milwaukee District Eyes Increasing Nature-Primarily based Flood-Mitigation Plan


The Milwaukee Metropolitan Sewerage District (MMSD) is mitigating flood dangers utilizing reforestation, wetlands restoration, and different nature-based options. MMSD has developed a roadmap for scaling up the challenge. Triple-I – in an evaluation requested by the district – has decided such an effort would enhance resilience throughout all of the metrics it thought-about.

In a current report – A Blueprint to Scale Up City Reforestation and Wetland Restoration in Underserved Communities Throughout the Larger Milwaukee Space – MMSD outlines its plan for the subsequent decade, which incorporates:

  • Planting 6 million timber;
  • Restoring 4,000 acres of wetlands;
  • Capturing an estimated 350 million gallons of stormwater with timber; and
  • Storing as much as an estimated 1.5 million gallons of floodwater in each acre of wetland.

The report included Triple-I’s evaluation, primarily based on its Group Resilience Rankings’ quantitative methodology.  Triple-I additionally harassed the advantages of community-based disaster insurance coverage applications incorporating parametric insurance coverage – insurance policies that pay out a set greenback quantity, regardless of the property injury incurred – for mitigating flood dangers.

“Group-based applications can incorporate a mixture of parametric insurance coverage and conventional indemnity protection,” the report acknowledged. “Not like indemnity insurance coverage, parametric constructions cowl dangers with out the problems of sending adjusters to evaluate injury after an occasion. As an alternative of paying for injury that has occurred, parametric insurance coverage pays out if sure agreed-upon situations are met. If protection is triggered, a fee is made.”

MMSD serves 28 communities within the Larger Milwaukee space and has already dedicated substantial sources to reforestation, wetlands restoration, and different nature-based options, together with inexperienced stormwater infrastructure initiatives.

“This dedication has positioned MMSD to construct upon its previous work to implement built-in nature-based options for stormwater administration on a big scale,” the report says. “To maintain up with rising flood threat, MMSD has dedicated to investing $294 million in watercourse and flood administration initiatives over the subsequent ten years…. It is a substantial enhance and can doubtless require MMSD to seek out new methods to generate funding to pay for these initiatives.”

The report outlines avenues that embrace federal and state funding sources, in addition to public-private partnerships and devices like environmental impression bonds (EIB) that may assist cities pay for progressive initiatives the place conventional sources of financing could also be tougher to entry. EIBs use personal capital for investments in environmental initiatives and are repaid primarily based on the challenge’s success in attaining its targets.
