Climate Change Preparedness of Great Lakes Communities

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.

Key Recommendations:

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

Bio-filtration practices such as spreaders, filter strips, and vegetated swales
Other urban practices such as box tree filters, green roofs, and permeable pavements

Climate Risks and Opportunities in the Great Lakes Region

The report features narrative context and analysis of publicly available data pertaining to the 653 counties in the eight Great Lakes states in the United States. Based on a composite rating, a priority list of Great Lakes counties has been produced that are best suited for intervention due to being highly at climate risk, with highly vulnerable populations, with highly agile workforces, and strong financial capacity.

  6. Availability of implementation partners
  7. Financing costs and benefits
  8. Risk management
Local Funding Strategies
These include general fund appropriations, new taxes, stormwater utilities, permit review and other special fees, etc.
Traditional Public Bonds and Loans
These include municipal bonds, clean water state revolving funds, drinking water state revolving funds, water infrastructure finance innovation act, etc.
Private Financing and Procurement Strategies
These include community-based public private partnerships, environmental impact bonds, pay-for-success, and stormwater credit trading.

Assessment of Market Size of Large-scale Use of Green Infrastructure in the Great Lakes Region

This report presents the findings of an initiative to expand the use of green stormwater infrastructure in the Great Lakes Basin through the use of private financing and/or private delivery. Presented here-in are assessments of the market size, key drivers of green stormwater infrastructure, benefits of private delivery/finance, and relevance of stormwater utilities.

Key Findings:

Market Size in the Great Lakes Basin
Stormwater utilities and their associated fees are an attractive means of repaying private investments. Ohio, Minnesota, Wisconsin, Illinois, and Indiana, collectively, have a large and growing number of stormwater utilities that generate a dedicated revenue stream, a portion of which could be used to support private financing/delivery of large-scale green infrastructure. We estimate that the potential market size for private investment in green infrastructure exceeds a billion dollars in these five states.
Market Drivers
Market drivers for private delivery and investment in large-scale green infrastructure are enhanced by community leadership, cost effectiveness, efficient and cheaper project delivery, performance based risk transfer, strong regulatory drivers, availability of dedicated stormwater funding, and P3-enabling legislations.
Relevance of Stormwater Utilities
Lack of a dedicated funding source limits the ability to attract private and public investment. New York, Pennsylvania, and Michigan have no or very few stormwater utilities in place limiting their ability to repay stormwater investments.
Status of P3 Legislations
Although the absence of a stormwater P3 legislation is not entirely prohibitive, its presence greatly facilitates the enactment of a P3. Only two Great Lakes states, Michigan and Indiana, have enacted P3 legislations for non-transportation projects. In other states, Home Rule authorities may be used to bypass the lack of P3 legislations.

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.

Key Benefits of a Stormwater Trading Framework to NEORSD:

Extension of current program
It is an extension of NEORSD’s current impervious cover fee program.
Retain Ownership and Governance
NEORSD and communities retain ownership, governance and decision authority that guides the framework.
Leverage optimal use
It allows the ability to leverage the uneven rate of economic recovery by prioritizing green infrastructure in areas of lower growth.
Costs of such a program are largely borne by developers.
Access to private properties
It is a flexible framework that will allow access to private properties in the service area.
Accelerated Delivery
Accelerated delivery of a large number of projects instead of delay due to lack of upfront capital.
Local Workforce Development
Workforce development, economic development, and other socially driven goals can be achieved if the framework is designed appropriately.
