A Blueprint to Scale Up Urban Reforestation and Wetland Restoration in Underserved Communities Across the Greater Milwaukee Area
This report examines Milwaukee’s history, changing rainfall amounts, capital improvements, and the need to enhance investments in nature-based solutions in underserved communities across the Greater Milwaukee region. Milwaukee Metropolitan Sewerage District (MMSD)’s Reforestation and Wetland Restoration (RWR) program is an ambitious 10-year initiative leading to a) planting of six million trees, b) restoring 4,000 acres of wetlands, c) capturing an estimated 350 million gallons of stormwater with trees, and d) storing up to an estimated 1.5 million gallons of floodwater in every acre of wetland. The report recommends the use of a Community-based Partnership (CBP) to scale-up this program and make the region climate-resilient.
Since 1950, average precipitation in Wisconsin has gone up by around 17 percent. Extreme rainfall events have become more frequent as well.
MMSD is a national leader and has committed substantial resources to the use of nature-based solutions (NBS) to address flooding and water quality issues.
Interviews with local community leaders suggest urban flooding is a top priority, followed by organizational capacity and funding; NBS has the potential to meet these priorities and build trust between government and the public.
Use of a CBP to scale up NBS across the MMSD service area, especially in underserved communities, is needed for delivery efficiency, cost savings, risk transfer, and dramatic socio-economic impacts.
MMSD is a national leader in the use of CBPs and as such, can leverage its existing experience to enable such a framework.
This study by HIP and CIS examines the triple-bottom-line benefits from Green Job Creation within Green Stormwater Infrastructure initiatives. Largest stormwater programs across the country that are studied here-in, include Milwaukee Metropolitan Sewerage District in Wisconsin, Prince George’s County in Maryland, Buffalo Sewer Authority in New York, and Philadelphia Water Department in Pennsylvania. Via a comparison of these large stormwater programs, our analysis describes key elements for bringing green jobs into communities nationwide. Thus, multi-faceted benefits can be achieved across environmental, social, and economic factors with an added focus on underserved communities.
Role Models for Future Programs
Each of the programs presented in this report has had extensive successes in their regions. For example, the Clean Water Partnership in Maryland’s Prince George’s County underscores the significant environmental and economic impacts achievable for the local community through innovative green stormwater infrastructure projects, supported by a comprehensive green jobs training pipeline.
Multiple Benefits of Green Employment
Green jobs within green infrastructure promote environmental conservation, reinforce social cohesion by weaving robust networks within local communities, and open avenues for economic advancement of citizens including in underserved communities.
Crucial Role of Training Initiatives
Comprehensive green job training programs with paid training opportunities ensure longer-term benefits and an effective transition towards a greener economy.
Strategic Partnerships in Stormwater Authorities
Pioneering stormwater authorities craft and nurture dynamic private-public community partnerships. These collaborations focus on the empowerment of local community stakeholders, along with training and education.
New(er) Government Funding
The Inflation Reduction Act (IRA) and Bipartisan Infrastructure Law (BIL) have resulted in an estimated (allocation of) $62.25 billion for water and stormwater infrastructure, including funding to support green job creation.
Guidance for Grant Aspirants
Prospective government-grant seekers should show multidimensional benefits. Projects demonstrably serving a triple bottom line (economic, environmental, social) can score higher, especially if focused on the needs of underserved communities.
A Blueprint to Scale Up Green Stormwater Infrastructure in Underserved Communities Across the Greater Chicago Region
This summary report examines regulatory compliance needs, changing rainfall amounts, capital improvements, and the need to enhance investments in underserved communities across the Greater Chicago region. The Metropolitan Water Reclamation District (MWRD) will need new, innovative delivery frameworks and new sources of financing to make the region climate resilient. The report recommends the use of a Community-based Partnership (CBP) that is already used elsewhere in the Great Lakes.
Rainfall during intense events across Greater Chicago has increased by 30 percent during the past 60 years and is expected to increase by 15 percent by 2050.
This increased precipitation means MWRD will need bigger and bolder solutions to manage the additional stormwater through a combination of grey and green stormwater infrastructure (GSI).
An analysis of the Space to Grow program in Chicago confirms that the schools selected for GSI installations are indeed located in underserved communities.
Interviews with local community leaders suggest safety, health, and community development are consistently top priorities; GSI has the potential to meet these priorities and build trust between government and the public.
Use of a CBP to scale up GSI across the MWRD service area, especially in underserved communities, is needed for delivery efficiency, cost savings, risk transfer, and dramatic socio-economic impacts.
This report examines changing rainfall amounts across five cities in the Great Lakes region. The focus of the report was to understand whether regulatory permits and community planning efforts are aligned to manage Climate Change-driven increases in rainfall, and found that wastewater facilities in these cities were issued their permits well before most recent precipitation estimates.
Combined Sewer Overflow (CSO) permits need to be updated
That “data stationarity” is not relevant anymore, needs to be communicated widely
Legislative reforms are needed to incorporate future climate data
Legislative reforms are also needed for communities to work closely with the private sector insurance industry
Alternatives to grey infrastructure must continue to be leveraged at large-scale
Options to make existing/future water (green or grey) infrastructure more efficient must also continue to be leveraged
Emphasis on upgrading infrastructure needs to continue
Funding for water infrastructure in general and green stormwater infrastructure in particular, at the federal and state levels, needs to be made available
Unlocking Clean Water State Revolving Funds to Finance Resilience Projects Across the Great Lakes Region
Established in 1987, Clean Water State Revolving Fund (CWSRF) have played a key role in improving water quality in the United States by providing more than $145 billion to finance more than 42,800 projects nationwide. This report looks at the current status of how CWSRF dollars have been spent across the Great Lakes states, and proposes greener priorities that would spur transformation in environmental, economic, public health, and social outcomes.
Recommendations to increase investment in green stormwater infrastructure (GSI):
Change legislation, agency goals, and project ranking criteria to promote GSI
Offer additional subsidies and sponsorship opportunities for GSI use
Develop local revenue streams and maintenance practices
Engage in outreach to foster enthusiasm for GSI
Utilize SRF-financed GSI investments to advance equity

Status of P3 Legislations
A Report to the Milwaukee Metropolitan Sewerage District Assessing Delivery and Finance Options to Implement Large-scale Green Infrastructure
After analyzing a variety of P3 options, project team recommends considering the use of either a CBP3 or an EIB for MMSD to meet its 2035 Green Stormwater Infrastructure vision. To enact a CBP3, MMSD doesn’t need private finance, and it can utilize its excellent credit rating to access best-fit public financing/funding strategies via various low-cost tax exempt and/or taxable capital sources, such as State Revolving Fund (SRF) and/or Water Infrastructure Finance and Innovation Act (WIFIA) loans, municipal bonds, existing property taxes and other general funds. Alternatively, MMSD can use an EIB that allows access to new capital and leverage a high degree of flexibility to scale innovations via a pay-for-performance framework.
Key benefits of a CBP3 to MMSD
- MMSD and communities retain ownership, governance and decision authority.
- MMSD and communities retain program savings.
- Accelerated delivery of a large number of projects.
- Private partner compensated on performance and achievement of aligned goals and objectives.
- Private partner retains risk for project delivery, maintenance, etc.
- Partner is responsible for the achievement of goals through the management of design, build, operation and maintenance processes.
- Workforce development, economic development, and other socially driven goals can be a CBP3 contract requirement.
Key benefits of an EIB to MMSD
- Ease of execution and access to new sources of impact capital, which can accelerate funding for innovative uses.
- Lack of a long-term encumbrance of an asset.
- High degree of flexibility to scale innovations and transfer risks from pilot projects.
- Meet the borrowers’ environmental and social objectives.
- Possibility of engaging multiple payors who benefit from green infrastructure projects (e.g., housing authority, economic development, public health, etc).
- Ability to use a variety of preferred delivery methods with the public borrower(s) retaining or transferring construction and maintenance risks to the private partner.
A Report to the Northeast Ohio Regional Sewer District Assessing Delivery and Finance Options to Implement Large-scale Green Infrastructure
A set of public-private partnership options were analyzed for NEORSD that included a CBP3, an EIB, and stormwater credit trading. Of these, stormwater credit trading emerged as the preferred partnership model for NEORSD. To have a successful credit trading program, NEORSD will need to to enact a new low-impact development ordinance, and an in-lieu option as well as a purchase guarantee of credits.
