Community-Based Public-Private Partnerships (CBP3s) as a Strategy for Project Implementation
How Public-Private Partnerships Work for Stormwater
Public-private partnerships (P3s) offer a practical approach to tackling the challenges of stormwater management. By using specialized funding and delivery models, they provide communities with effective solutions for improving stormwater infrastructure. Let’s break down the key differences between traditional P3s and their more community-focused counterpart, CBP3s.
What Are P3s and CBP3s?
Traditional public-private partnerships (P3s) have long been used in sectors like transportation, energy, and water systems. These partnerships typically focus on addressing the need for upfront financing – municipalities collaborate with private companies to fund infrastructure projects they might not otherwise afford.
Community-Based Public-Private Partnerships (CBP3s) take this concept further. As Andrew Smith from Black & Veatch explains:
"The fundamental difference between the two [P3s and CBP3s] is the market need each seeks to address. Financing is a primary driver for a traditional P3… In contrast, CBP3s address a delivery need that transfers greater risk and accountability to the private sector and are ‘financing agnostic.’" [2]
In other words, while traditional P3s focus on funding, CBP3s prioritize efficient, accountable delivery of solutions tailored to community needs. CBP3s are particularly well-suited for stormwater management, emphasizing green infrastructure projects that boost local economies and enhance urban living – especially in underserved areas.
The financial model of CBP3s is another standout feature. These partnerships can combine public funding with private investment at a ratio of 10:1, generating nearly three times the economic return for every public dollar spent [1]. For example, communities have reported over $2.50 in economic stimulus for every dollar invested [2].
CBP3s also stand out for their long-term approach, often covering 20–30 years of maintenance. This ensures that infrastructure remains effective over time while delivering sustained economic and social benefits [2]. The U.S. Environmental Protection Agency highlights this shift:
"A CBP3 model evolves the standard P3 contractual mechanism into a true partnership that focuses on improving water quality and a community’s quality of life." [1]
This evolution makes CBP3s particularly effective in addressing the complex demands of stormwater management.
Why CBP3s Work Well for Stormwater Projects
Stormwater management is no small task. It often involves maintaining hundreds – or even thousands – of installations scattered across a community. While traditional design-bid-build methods can handle single projects, they struggle with the scale and complexity of large retrofit programs.
CBP3s excel in these scenarios because they shift more risk and responsibility to private partners who bring specialized expertise in managing multi-site projects [2]. These private entities often have access to advanced technology and streamlined project management systems that municipalities may lack.
One major advantage of CBP3s is their ability to meet regulatory deadlines efficiently. Their delivery speed and technical know-how make them ideal for ensuring compliance with environmental regulations. For instance, Maryland has used CBP3s to align with its goals for sustainable urban infrastructure.
Take the Fresh Coast Green Communities (FCGC) program in Milwaukee as an example. Launched in 2022, this $31.5 million CBP3 – developed by the Milwaukee Metropolitan Sewerage District and Greenprint – has already made a significant impact. The program has implemented 90% of its projects in areas with high social vulnerability and awarded 45% of project work to small, women-, and minority-owned businesses, surpassing its 30% target [5].
Similarly, Prince George’s County, Maryland, was an early adopter of the CBP3 model with its Clean Water Partnership in 2015. Partnering with Corvias Solutions, the county assigned the private sector responsibility for design, construction, operations, and maintenance. Notably, Corvias pledged to allocate 30–40% of project work to small and minority-owned businesses [4]. The county even ran a parallel green infrastructure program to compare the CBP3’s effectiveness against traditional methods during the first three years [4].
Another benefit of CBP3s is their flexibility. While some assume these partnerships require fixed-price contracts, many successful programs use Guaranteed Maximum Price (GMP) contracts. These contracts ensure cost transparency and allow any savings to be reinvested into additional community projects, unlike fixed per-unit pricing, which can sometimes lead to cost-cutting measures [3][5].
What truly sets CBP3s apart is their community-first approach. With performance-based metrics and contractual flexibility, these partnerships encourage local business participation, create jobs, and support educational initiatives, leaving a lasting impact on the communities they serve [2].
Key Stakeholders and Management in Stormwater P3s
The success of stormwater public-private partnerships (P3s) hinges on well-defined roles and strong accountability. Each stakeholder brings specific expertise to the table, and effective management systems help projects stay on track while meeting both regulatory and performance standards.
Public and Private Partner Responsibilities
Public agencies handle strategic oversight, monitor performance, ensure regulatory compliance, and engage with the community. They also coordinate efforts across departments and retain final approval authority for projects. For example, municipal stormwater departments oversee MS4 permit compliance, manage budgets, and ensure adherence to local zoning and environmental regulations.
On the other hand, private partners are responsible for executing the projects. This includes managing financing, design-build processes, daily operations, and long-term maintenance. Beyond construction, private entities often take charge of long-term asset management, which involves routine upkeep, performance monitoring, and system upgrades.
A key element of these partnerships is risk allocation. Private partners typically assume risks related to construction, performance, and maintenance, while public agencies manage risks tied to regulatory and policy issues. This division allows each party to focus on areas where they are most experienced.
Local contractors and subcontractors also play an important role by contributing specialized skills, such as excavation, landscaping, and material supply, which are critical for the project’s success.
These clearly defined roles allow for the establishment of effective oversight mechanisms to ensure accountability.
Oversight and Accountability Systems
Accountability in stormwater P3s is reinforced through performance-based measures that build on the responsibilities of each partner. Performance-based contracts are a cornerstone of this approach, setting specific metrics for water quality improvements, infrastructure performance, and maintenance standards. Payments are often tied to achieving these targets, ensuring alignment with project goals.
Milestone payments help maintain steady progress by tying compensation to key achievements, such as design approval, construction completion, performance testing, and annual maintenance reviews. This phased approach allows for adjustments as needed while keeping the project on schedule.
Compliance checkpoints ensure adherence to regulatory requirements, including MS4 permits and Chesapeake Bay TMDL goals. For instance, in Maryland, these checkpoints are used to track measurable progress in nutrient reduction and stormwater volume management. Regular monitoring and reporting further ensure that projects align with broader environmental objectives.
Third-party oversight adds an additional layer of accountability. Independent environmental consultants and engineering firms may verify water quality improvements, audit construction practices, and review maintenance efforts, providing an unbiased assessment of project performance.
Financial accountability is upheld through budget reviews, cost reporting, and audits. Many P3 agreements use Guaranteed Maximum Price contracts, which cap costs and allow any savings to be reinvested into additional community projects.
Community input is another key element of oversight. Public meetings, online dashboards, and dedicated liaisons ensure that local concerns and needs remain central to the project. Technology also plays a crucial role, with tools like digital monitoring systems, GIS mapping, and real-time data collection offering continuous insights into project performance and environmental outcomes.
Financing and Delivery Methods for Stormwater P3s
Public–private partnerships (P3s) in stormwater management create a collaborative framework where public funds combine with private-sector expertise to develop and maintain green infrastructure. This approach not only helps streamline projects but also ensures regulatory goals are met while building local expertise.
How Stormwater P3 Financing Works
A standout example in Maryland is the Clean Water Partnership. Here, the private partner takes charge of design, construction, operations, and maintenance. Maryland also taps into regional financing platforms like the EPA Region 3 Sustainable Stormwater Financing Forum and the Chesapeake Bay Trust-hosted CBP3 Summit. These platforms are key to sharing strategies for smarter financing and effective project execution.
Delivery and Payment Structures
The Clean Water Partnership uses a performance-based model, ensuring that project delivery aligns with specific, measurable outcomes. A unique aspect of this model is its local economic development requirement. It mandates that 30–40% of the project work involves small and minority-owned businesses. For instance, local contractors like Pro Landscapes MD have the chance to showcase their stormwater management skills, creating opportunities for community engagement and growth.
These financing and payment models pave the way for deeper discussions on the benefits, challenges, and compliance needs tied to stormwater P3s.
