Tackling Water Infrastructure and Coastal Challenges in Michigan
Ann Arbor-based CIS was founded in 2013 by Corvias, a Rhode Island-based company that provides infrastructure services to the military, state and local governments, and higher education. In 2023, it was spun off as an independent company whose services center on solving the complicated challenges of outdated and ineffective stormwater infrastructure. SBN Detroit interviewed the company’s CEO, Sanjiv K. Sinha, Ph.D., and Sri Vedachalam, Ph.D., Senior Director of Water Equity and Climate Resilience, about two recent projects – an advisory and research project focused on coastal conservation for The Nature Conservancy, a global conservation nonprofit, and an analysis of Great Lakes Regional Poll (GLRP) data for a binational federal agency. Q: What were the primary goals of the coastal conservation analysis services you provided for The Nature Conservancy? Vedachalam: The main goal of this project was to conduct a comprehensive scoping exercise to identify and understand the key challenges faced by Great Lakes communities in relation to fluctuating water levels, high-energy waves, and climate-induced shoreline erosion. Shoreline erosion in particular is becoming increasingly prevalent due to climate change, and our focus was to assess how these environmental stressors impact both the natural and built environments. By gaining a clearer understanding of these challenges, our goal is to help surrounding communities become more resilient. This involves preparing infrastructure to withstand the ongoing and future effects of these changes. Q: What are the key environmental challenges currently affecting coastal areas in Southeast Michigan and the broader Great Lakes region? Vedachalam: Coastal areas in the Great Lakes region face a variety of interconnected challenges, mainly involving three key components: the lake itself, the shoreline, and the watershed. Rising and fluctuating water levels, coupled with stronger energy waves, contribute to significant shoreline erosion. These forces can disturb lakebed sediments, which, in turn, impact aquatic organisms and their habitats. In addition, increased rainfall—often intense and unpredictable—introduces higher levels of pollutants and contaminants into the lakes, further exacerbating environmental stress. The watershed is also heavily affected by these factors, particularly in terms of increased flooding, which places additional strain on both natural ecosystems and human infrastructure. Addressing these challenges requires a multifaceted approach that combines both natural and engineered infrastructure to mitigate damage and enhance community resilience. Sinha: To add some context, climate change is causing regions around the Great Lakes to experience more rainfall in shorter periods of time, leading to severe issues such as flooding and water quality challenges such as algal bloom in western Lake Erie. The frequency and intensity of these rain events are increasing, which complicates regional water management. As an example of changed rainfall, based on 1992 estimates, a hundred-year storm in Detroit used to be 4.4 inches of rainfall, while in 2019, a similar storm produced 5.2 inches—an additional two billion gallons of water. According to SEMCOG, by 2050, storms of this nature could result in 7.7 inches of rainfall, adding another six billion gallons of water. Preparing communities and infrastructure for such occurrences is essential as we look toward the future. And these massive challenges present an incredible opportunity for the region to grow its economy by deploying capital that leads to local jobs. Q: Based on this project, what specific actions or solutions is CIS proposing to protect Great Lakes coastal communities? Vedachalam: It will take a balanced approach that integrates both hard infrastructure and nature-based solutions to address the complex challenges these coastal communities face. One focus is wetlands, which historically covered vast areas across the Great Lakes region. Over time, urbanization has led to the loss of many of these wetlands, reducing their ability to naturally manage stormwater. So, we need to design infrastructure to help slow down stormwater runoff before it reenters the lakes. Additionally, we need to stabilize dunes and other natural barriers, which play a critical role in protecting the shoreline from erosion and the impacts of fluctuating water levels. These natural elements act as a first line of defense, mitigating the force of incoming water while preserving ecosystems. Another critical area of focus is people. It’s crucial to involve residents in these efforts to ensure that the solutions we propose are compatible with how people live and interact with these spaces. Through collaborative efforts with the community, we can foster a sense of ownership and ensure that the projects we implement meet both environmental and societal needs. Q: What unique opportunities or risks does Southeast Michigan face regarding water management and coastal resilience compared to other areas of the Great Lakes? Vedachalam: Southeast Michigan presents a unique mix of challenges. Historically, this region was rich in biodiversity, with vast expanses of marshes and wetlands serving as natural buffers against flooding and erosion. However, as the area became more urbanized and industrialized, many of these natural systems were altered or lost. Despite this, there remains a kind of “ecosystem memory,” where there is potential to restore these natural practices and processes in some areas. One of the main challenges the region faces is balancing the needs of a highly industrialized and sprawling urban environment with the goal of restoring natural systems. Legacy pollution from past industrial activities continues to pose a risk. There is growing interest from communities to return to more sustainable, nature-based solutions. Q: To this end, what is the importance of polling data in understanding public sentiment on Great Lakes water issues? Vedachalam: Polling data is critical because it allows us to measure public sentiment at a specific point in time and over time. Public sentiment can be dynamic, especially following significant events, much like we see in political polling. Attitudes often shift slowly over time, so conducting annual polls helps track these changes and offers insights into how public perceptions and concerns evolve. Sinha: The Great Lakes represent a highly complex system, involving eight U.S. states and two Canadian provinces. This vast geographic area makes it essential to carefully assess how public sentiment varies across the region. Polling helps identify which stakeholders hold specific concerns and how
SEMCOG Working to Develop Plan to Reduce Greenhouse Gas Emissions
The Detroit-Warren-Dearborn Metropolitan Statistical Area (MSA) recently was allocated $1 million to develop a plan for reducing greenhouse gas emissions and other harmful air pollution through the US-EPA’s Climate Pollution Reduction Grants (CPRG) program. The plan will cover the MSA’s six counties – Wayne, Oakland, Macomb, St. Clair, Livingston, and Lapeer – as well as Washtenaw and Monroe counties. The Southeast Michigan Council of Governments (SEMCOG), which is the lead agency for Southeast Michigan’s Climate Action Plan, will manage the funds. The plan is in place to help local governments improve and maintain Southeast Michigan’s transportation systems, environmental quality, economic interests, and infrastructure. SBN interviewed SEMCOG Planning Director Kevin Vettraino about what this will involve, how it will roll out, and how it impacts businesses, residents, and communities in Southeast Michigan. Q: Tell us about SEMCOG. A: SEMCOG is the regional planning organization for the seven counties that make up the Southeast Michigan region: Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne counties. Our primary mission is to support our local government members, including counties, cities, villages, townships, and educational institutions. We work to improve the quality of the region’s water, make the transportation system safer and more efficient, revitalize communities, and spur economic development. These things shape the areas we get involved in. I like to say we focus on planning for the issues or opportunities that cross geographic or community boundaries, such as roads, rivers, lakes, air, and the economy. Q: The U.S. Environmental Protection Agency allocated $1 million to develop plans for reducing greenhouse gas emissions, and SEMCOG is acting as the lead agency to develop a climate action plan. What will this entail? A: At a high level, the plan will establish community-developed and evidence-based methods to reduce greenhouse gas emissions that will meet the requirements of the EPA and CPRG. One approach is to enhance natural areas that capture carbon. The plan will also integrate extensive stakeholder outreach and input, along with equity considerations, and consider the impact of policies, strategies, and actions from the regional level down to the household level. This work complements the recently adopted Southeast Michigan GREEN: Strategic Framework for Growing our Resilience, Equity, and Economy with Nature, which is an initiative to address some of the region’s most pressing challenges – managing floods, fostering climate resilience, improving community health, and protecting our natural assets – all while creating vibrant places where people want to live and where businesses will thrive. Q: What is the next step and timeframe for action? A: The next step will be launching a task force with the intent to meet at least eight times over two years. Part of the large overarching task force will be smaller focus groups that will cover more specific parts of the plan. The focus groups have not been formed yet, but they are likely to focus on transit, energy efficiencies, EVs and the impacts of the transition, materials management, and nature-based opportunities and impacts. Beyond the focus groups is community engagement. This is critical for success. It’s important for us to have a two-pronged approach here, that being education and data sharing and also public engagement and input. Q: What does community engagement entail? A: Surveys, local meetings, webinars, and other outreach with a lens toward ensuring that the benefits and policies that come out of this work support all residents, including lower-income residents. These people have traditionally been underrepresented and more impacted, and we need to ensure that any actions we take support them and don’t further negatively impact them. Q: How will this impact Southeast Michigan businesses and communities? A: My hope is that through our work there is an education component. In basic terms, we need to make sure we are speaking the same language. There are a lot of terms around climate action such as equity, green infrastructure, etc., and we need to ensure that whether you are a business, community, government entity, or a resident, we all have a similar understanding regarding what these terms mean and why they are important. I hope that business leaders can see themselves within the strategies, policies, and actions that come out of this work and align with them. We all have a role to play in this. This plan will not be the silver bullet that can solve the climate challenges in the region but all of us together can make an impact. From installing a green roof or rain garden to ensuring all people have safe facilities to walk or bike to destinations, whether it’s a sidewalk or bike path or considering nature-based and green infrastructure solutions when putting in a new parking lot or reconstructing a roadway, there are things we all need to be thinking about and doing. Q: What are your main challenges? A: Again, it’s getting a common set of words and a familiar language. It’s also about education and making everyone understand the importance of the plan, and working toward a healthier region, and putting sustainability practices in place to support our climate long into the future. A lot of our work targets dates far into the future, such as 2050, and sometimes it’s difficult to get buy-in when it’s so long-term. The challenge is we need buy-in and immediate action to get to where we want on the horizon. Q: What are the main opportunities? A: First, we have the $1 million funding to help develop a plan, inventory our greenhouse gas emissions, and develop policies – which is great. Through the development of this plan, the region and our communities and businesses will become competitive for an estimated $4.6 billion in EPA grant funding for implementation. Second, if we are able to get folks both in leadership and residents across the region to both understand the importance of the action plan and to be intentional about environmental justice and the allocation of funds and the action to support those directly impacted, that is a great success.
