Becoming a Water Positive City

October 15, 2024
By Bill Alms, Sr Project Manager, WSB

As the world grapples with the challenges of climate change and urbanization, the concept of water positivity has emerged as a crucial goal for cities striving for sustainability. Water positivity means a city gives back more water than it consumes, creating a net positive impact on the local water cycle. Achieving this status is not only environmentally responsible but also enhances the resilience and livability of urban areas. Here are some essential tips for city staff on how to transform your city into a water-positive organization.

Implement Efficient Water Management Practices

The first step towards water positivity is to adopt efficient water management practices. This includes the installation of smart water meters and leak detection systems to monitor and reduce water wastage. Cities should invest in upgrading their infrastructure to minimize losses from aging pipelines and optimize water distribution. Additionally, promoting water-saving technologies and practices among residents and businesses can significantly reduce overall consumption.

Invest in Green Infrastructure and Regenerative Landscapes

Green infrastructure, such as rain gardens, green roofs, and permeable pavements, plays a vital role in enhancing water infiltration and reducing runoff. These systems help to recharge groundwater, mitigate flooding, and improve water quality by filtering pollutants. By integrating green infrastructure into urban planning, cities can create more resilient and sustainable environments that support water positivity.

Promote Water Recycling and Reuse

Encouraging water recycling and reuse is another key strategy for achieving water positivity. Cities can implement greywater systems to reuse water from sinks, showers, and laundries for irrigation and other non-potable purposes. Additionally, investing in advanced wastewater treatment technologies can enable the safe reuse of treated effluent for industrial processes, landscape irrigation, and even potable water supply. Educating the public about the benefits and safety of water reuse is crucial for gaining community support.

Enhance Community Engagement and Education

Building a water-positive city requires the active participation of the community. City staff should develop comprehensive education and outreach programs to raise awareness about water conservation and the importance of sustainable water practices. Engaging with local schools, businesses, and community organizations can foster a culture of water stewardship and encourage collective action towards water positivity. Transparency in sharing data and progress can also build trust and motivate residents to contribute to the city’s water goals.

Placing an emphasis on telling the water positive story through engaging dashboards and communication strategies is essential. Effective communication needs to tell the story of why it’s important and allow the community to track their progress towards achieving its water-positive goals. This may be on a 20-50 year timeline, as this transformational shift will not happen in short-term planning horizons.

Collaborate with Experts and Stakeholders

Achieving water positivity is a complex and multidisciplinary task that requires collaboration with experts and stakeholders. Partnering with environmental organizations, academic institutions, and technology providers can provide cities with the knowledge, tools, and resources needed to implement effective water management strategies. Additionally, fostering partnerships with neighboring municipalities and regional authorities can enhance the impact of water-positive initiatives on a larger scale.

In conclusion, transitioning to a water-positive city is a multifaceted endeavor that demands commitment, innovation, and collaboration. At WSB, we have the expertise and resources to support cities in their journey towards water positivity. Our team of experienced professionals can provide tailored solutions and guidance to help you implement efficient water management practices, invest in green infrastructure, promote water recycling, and engage your community.

Stormwater Management & Planning in Expanding Communities

August 1, 2024
By Jake Newhall, Director of Water Resources and Samuel Phillips, Water Resources Engineer, WSB

As communities grow, the challenge of stormwater management becomes increasingly complex. The key to success lies in proactive planning and the strategic development of infrastructure that can adapt to future growth. Learn more about strategies for effective stormwater management in growing communities.

Impact of Population Growth on Stormwater Systems
With urban expansion comes the inevitable addition of impervious surfaces – concrete, asphalt, and roofs, for example – which significantly increases stormwater runoff and alters natural drainage patterns. These changes make communities more vulnerable to flooding and localized erosion, pushing existing infrastructure to its limits and leading to environmental degradation.

Strategic Infrastructure Planning
Effective stormwater management starts with comprehensive planning. Communities need to integrate stormwater management considerations into all stages of development. This includes assessing the potential impact of new construction on stormwater runoff and making necessary adjustments to the stormwater system in early planning phases. It is critical that the planning factors in the existing regulatory framework at the state level, e.g., MPCA regulations in Minnesota, or at local level, e.g., Watershed Districts or city regulations.

Incorporating Flexibility in Infrastructure Design
To accommodate growth, stormwater systems must be designed for flexibility and scalability. This involves creating systems that can be expanded or adjusted as the population grows and land use changes. Techniques such as flow rate control structures, expandable stormwater detention facilities including underground storage are vital. These systems ensure that the infrastructure can evolve in step with the growing community’s needs, without requiring complete overhauls. Often it can be beneficial to plan stormwater management at a regional level, rather than on a project-by-project basis.

Surface Water Quality
In recent decades the stormwater management focus has shifted from traditional rate control through detention towards water quality and volume reduction. Runoff retention, infiltration practices, and erosion control techniques are essential components of the infrastructure planning. Creative solutions such as biofiltration or underground infiltration play an important role in keeping the sediment and nutrient loads at a minimum to preserve healthy riverine and lacustrine ecosystems.

Enhancing System Resilience Through Advanced Engineering
Employing advanced engineering solutions can significantly boost the efficiency and resilience of stormwater systems. For instance, real-time monitoring systems can provide immediate data on water levels, flow rates and system performance, allowing for swift responses to potential flooding events. Additionally, automated control systems can dynamically manage gates and pumps to optimize water flow during different weather conditions.

As communities build resilient infrastructure in growing areas, it may be desirable to bring enhanced stormwater infrastructure to previously developed areas. This is often a challenge, as space may be limited. Hydraulic and water quality modeling can be useful tools in completing subwatershed assessments to identify optimal areas for improvement.

Community Engagement and Education
Community involvement is crucial for the success of stormwater management strategies. Educating the public about the importance of reducing surface runoff and maintaining personal property to aid in water absorption can have profound effects. Community-based initiatives, such as rainwater harvesting and the proper maintenance of private drainage systems, complement larger infrastructure projects and empower residents to contribute to the health of their environment.

Economic and Regulatory Considerations
Planning for the economic aspects of stormwater management is as critical as the technical components. Funding mechanisms, whether through local government budgets, grants or public-private partnerships, need to be established. Moreover, robust regulatory frameworks that mandate sustainable stormwater practices in new developments can drive compliance and ensure that growth is managed in an environmentally responsible manner.

How WSB Can Help
Managing stormwater in a growing community requires foresight, innovation, and community collaboration. At WSB, we provide expert consulting and engineering services that help communities plan, design, construct and maintain flexible, efficient and cost-effective stormwater management systems. Our approach ensures that your infrastructure not only meets today’s needs but is also prepared for tomorrow’s challenges.

Pond sediment removal

Assessing the effectiveness of pond sediment removal

July 15, 2024
By Jake Newhall, Director of Water Resources, WSB and Bill Alms, Project Manager in Water Resources, WSB

WSB is Leading a New Study that Will Assess the Effectiveness of Pond Sediment Removal for Phosphorus Management in Stormwater Ponds.

Stormwater ponds are an effective way to treat and control stormwater runoff. However, recent studies have indicated that there may be an increasing threat of phosphorus being released from stormwater ponds that can increase pollutant loading to lakes, streams, and wetlands. To address this concern, WSB, the University of Minnesota and six Minnesota communities have come together to perform a study funded by the Minnesota Department of Transportation Local Road Research Board. This study will provide practical data that will help communities across Minnesota manage their stormwater ponds and ultimately improve water quality.

With that in mind, here is what communities and their residents can expect.

What Does The Study Entail?

Six Minnesota communities – Maple Grove, Plymouth, Prior Lake, Savage, Burnsville and Woodbury – will each provide one stormwater pond project to be used as the basis of the study. During the summer of 2024, researchers will visit each pond, take sediment samples and run analysis to determine how much phosphorus is in the basin and how much phosphorus release potentially exists. Then, in the winter of 2024, each pond will undergo a pond dredging project that removes sediment buildup. Following the dredging projects, new samples will be taken during the summer of 2025 to analyze and determine whether current maintenance processes for stormwater ponds can address phosphorus release concerns.

Why Is The Study Needed?

Minnesota has over thirty thousand stormwater retention ponds that treat and control stormwater runoff, but also risk discharging pollutants that impact water quality. Additionally, stormwater ponds are used across the country, meaning that if current dredging practices are not working as intended, the data gathered by this study will directly impact stormwater management regionally and nationally. Primarily, this study will provide much needed data to make new recommendations on how to tackle and prioritize maintenance to maximize pollutant removal.

Phosphorus is particularly detrimental to water quality as it causes the growth of algae in lakes and rivers. Algae blooms not only lower water quality, but also reduce oxygen in the water and are toxic to people and wildlife alike, with studies attributing algae blooms as a potential cause for detrimental health conditions.

What Is WSB Doing To Help?

WSB’s team of experts understand how to manage and improve water resources. WSB is innovating, looking at the science and developing cutting edge tools and techniques to help communities better manage stormwater runoff and water quality. As the study commences and the final data sets are made available in 2025, the work of our talented team will provide the information necessary for communities in Minnesota and across the country improve their programs and to protect their water and their residents.

Capture Federal Funds to Build Resilient Stormwater Infrastructure

By Jake Newhall, Director of Water Resources, WSB
April 15, 2024

Stormwater infrastructure around the country is being put to the test by age and deterioration as well as climate change events and abnormal weather like droughts and unusually intense rainfalls. With that in mind, communities need to follow five steps in order to create resilient stormwater infrastructure. The goal is to limit stormwater-related risks and to properly fund critical projects. Those steps can be simplified down into Identification, Project Development, Planning, Funding and Building.

Identifying Infrastructure Needs

Knowing is half the battle. Before a project can begin, a community must understand what their needs are with a specific focus on aging and failing infrastructure. If stormwater infrastructure fails, roads, nearby buildings and residences could be put at risk.

Developing a Resilient and Sustainable Project

The project development step is where you answer a multitude of questions on the project’s objectives and scope. First and foremost, is the project feasible from a financial or construction standpoint? What resilient solutions are being included to properly develop the updated infrastructure so it will last? In addition, what are the benefits of the project? Identifying the problem and answering these questions will allow for a much easier transition into the next steps like applying for grant funding. For example, regular maintenance of existing infrastructure will find little opportunity for grant funding. Developing your project with the set goal of improving infrastructure to become more sustainable and resilient will drastically improve your chances.

An example of improved resiliency is developing your infrastructure to respond to changing climates and abnormal weather conditions. Is your infrastructure project designed to handle prolonged droughts or intense rainfalls or intense snow melts?

From a stormwater perspective, a more sustainable project can include aspects like increased storage and volume control and a more efficient outlet system. Being able to retain the stormwater on site and slowly release it to downstream systems will not only better protect your community and those downstream, but can also lead to improved water quality.

Planning For Success

The third step can be simplified into making a plan. Collecting every aspect of the project into a planning document will set up a community for success. With no absolute assurances that grant funding will be accessible, the planning step gives communities the confidence that their project and the intent to update and revitalize their stormwater infrastructure, is not just a hope, but a tangible path to success.

Obtaining Grant Funding

The next step is grant funding. Recent policies from the federal and state government have created ample opportunity for bringing greater resiliency to stormwater infrastructure. For example, the Infrastructure and Jobs Act included over $50 billion in available federal funds towards drinking water, wastewater and stormwater infrastructure. Similarly on the state level, the Minnesota Pollution Control Agency recently announced $35 million in grant funding for stormwater resiliency projects. There are a variety of types of grants that all focus on different goals.

Building Resilient Stormwater Infrastructure

Finally, once all the previous steps have been completed to satisfaction, the final phase of developing resilient stormwater infrastructure is building. During this step, the project is fully designed and construction begins. As the final step is completed, your community will have transformed aging infrastructure into a success story that protects your community, those around it, and creates a more sustainable environment.

How WSB Can Help

The vast knowledge and experience at WSB will help clients find solutions to stormwater management. If a community has identified a need, WSB can build off even a tiny idea to help make it fit from project development all the way through construction. With WSB’s talented team of experts, a community will have a trusted partner who can help ensure a project is funded and built efficiently and effectively.

What Does the Mild Winter Mean for Spring

March 11, 2024
By Jake Newhall, Director of Water Resources, Mary Newman, Sr Environmental Scientist, and Emily Ball, Forestry Program Manager, WSB

As Midwesterners, we always expect Mother Nature to throw us some curveballs when it comes to weather. The winter of 2023-2024 has been no exception. El Nino weather patterns created unusually mild weather this winter and less snowfall. While cities may have benefited from things like fewer snow emergencies, what do these weather patterns mean as we head into spring?

Here are a few things to consider.

Stormwater Runoff

The lack of snowfall and warmer temperatures means that the ground is warmer than normal and contains less frost since there is not a layer of snow insulate the ground. The lack of precipitation and snowmelt could lead to drought this spring and into summer. Alternatively, if we do end up with significant snowfall in March and April, the thawed ground will allow water to absorb straight into the ground, resulting in less runoff and replenished groundwater sources.

If we don’t receive significant precipitation this spring, pond and lake levels are also expected to be lower than normal. While drought is a concern, the good news is that lower water levels provide an excellent opportunity for stormwater inspections. Other good news from a mild winter is that we are likely to see fewer environmental impacts this year from sanding, salting and runoff than in years with heavier snowfalls.

Lakes, Rivers and Streams

When thinking about water quality, it’s also important to think about what this mild winter will mean for lakes, rivers and streams.

Lack of snow cover and ice means that aquatic vegetation will have an early start this spring and likely result in an abundance, especially with invasive curly leaf pondweed. The increased abundance will have an impact on phosphorus levels in the water as these plants die back in the late summer. If the warm weather and low precipitation levels continue, this could mean a higher likelihood of harmful algal blooms which can put pets and animals at risk when they drink the water. However, the increased cover may benefit the aquatic community in the meantime for those that depend on its cover for survival.

Many water managers have a plan for invasive curly leaf pondweed management. This year, harvest may have to occur earlier and more often to combat a late season phosphorus rise. As in most years, it will also be important to monitor algal blooms and inform lake users if sampling indicates harmful bacteria levels that would have an impact to human and animal health.

Trees and Invasive Species Management

For communities managing tree health, it’s also critical to explore how this year’s mild winter will impact trees. With many places in dry or moderate drought conditions, more trees will experience drought stress. If precipitation patterns continue, it’s important to build out a plan for regular watering throughout the summer to protect trees. Furthermore, drought stress and lack of adequate watering can make trees more susceptible to secondary pests.

The lack of subzero temperatures this winter also means that the invasive species Emerald Ash Borer (EAB) larva largely survived the winter. It takes 24-48 hours of temperatures of -30 degrees Fahrenheit to kill EAB larva. EAB is a serious concern to ash trees across the United States, occurring in 30 states including Minnesota, Colorado, and Texas.

Oak wilt disease is another concern. The normal oak pruning season is typically from November through early April to prevent oak wilt transmission. For 2024, it will end earlier, oak tree pruning should be stopped immediately to protect tree health and limit the spread of oak wilt. The University of Minnesota Extension provides an oak wilt status page on their website that should be monitored closely each spring to ensure you aren’t pruning during high-risk oak wilt season.

Build Resilience into Water Reuse Infrastructure and Systems

August 14, 2023
By Bill Alms, Project Manager, WSB

The Midwest is experiencing a drought this summer. High temperatures and scarce precipitation have led many communities to implement watering bans and other solutions to help manage limited water resources.

For community leaders, it’s crucial to recognize that addressing drought and the impacts of climate change is a marathon, and not a sprint. While drought is top of mind for communities right now, it is equally essential to adopt a long-term perspective, and explore investing in systems and infrastructure that will minimize the impacts of drought and flooding in the long term and protect potable water supplies.

How can communities think long-term about water resiliency, reuse systems and planning? Here are some things to consider.

Invest in Resilient Water Systems that Can Handle Climate Extremes

Cycles of drought and flooding are becoming more common as global temperatures rise. Ensuring access to clean, safe water is critical for communities, and that means investing in infrastructure and water reuse systems that are efficient, effective and resilient.

WSB worked with Hugo, Minnesota on a sustainable water reuse strategy more than a decade ago, helping them build resiliency into systems. From reducing potable water use in landscaping, to placing reservoirs in strategic locations to ensure adequate water supply for high use areas, to educating the public on the importance of water conservation and reuse, the city’s water reuse strategy has been successful. It’s also made their water systems less susceptible to drought and climate change.

Communities looking to find similar success should approach water reuse and infrastructure in steps.

  1. Start with a feasibility analysis. Communities should begin with a feasibility analysis to determine areas with the lowest water supply, high water consumption, and inefficiency points. Based on this analysis, authorities can establish priorities, discerning which places require the most water and where there is greatest demand. Facilities like athletic complexes, schools, and manufacturing plants, which consume substantial amounts of water, should be evaluated accordingly. Pairing a usage map with existing sources can help determine how to build a more integrated and efficient system.
  2. Think regionally. It’s important to think regionally when planning for water reuse systems instead of site by site. How far apart are water sources? Where is the greatest consumption? Thinking about how pump systems can serve larger areas, placing retention ponds in strategic locations best suited to collect stormwater, and connecting water sources across a community promotes greater efficiency and benefits the environment, especially under drought conditions.
  3. Understand the value of long-term investments. When investing in more resilient water reuse systems, communities may be deterred by significant upfront costs, but the long-term benefits are significant. Communities should look at water reuse systems like other utilities and how to best maximize return on investment for everything from pumps to irrigation systems, to reservoirs. Adopting large-scale water intake and distribution infrastructure to meet specific needs minimizes water waste, as well as reduces the negative impacts from drought and flooding cycles. Numerous grants and funding sources are available to help design and implement water reuse projects.
  4. Engage residents. Public buy-in for reuse systems is important to foster conservation best practices and reduce the strain on groundwater reservoirs. More efficient systems and incentives for users can also significantly reduce the strain on water supply systems.
Take Advantage of the Drought

In the short term, many water basins are running low or are dry. While this situation poses many problems for communities, and reinforces the importance of resilient water reuse infrastructure, drought also provides an unexpected opportunity for critical maintenance work. Routine maintenance or fixing erosion or failed intakes and outfalls, for example, can be difficult when water levels are normal or high. Low water levels provide a meaningful opportunity to ensure systems are functioning properly, and access equipment that may normally be underwater.

How Can WSB Help?

WSB offers a wide range of services to assist cities and communities in implementing effective water conservation practices, especially in dealing with the challenges posed by aging infrastructure and extreme weather cycles of drought and flooding.

WSB provides tailored solutions for every community, and can help with feasibility analysis, design of reuse systems, public engagement, securing grant funding for projects and more. WSB empowers communities to ensure the longevity and functionality of their water-related assets, fostering sustainable water conservation practices for the future and more resilient systems.

Supporting the Infrastructure of an Entire Community

July 18, 2023
By Brian Bourassa, VP of Corporate Development

Investing in the vitality of the city of Lino Lakes, Minnesota.

At WSB, we use the term infrastructure broadly to define the places, spaces and systems that support our lives.  As important as infrastructure is to our way of life, we don’t often think about it until something goes wrong.  We’ve been privileged to support communities across the U.S. with their infrastructure needs. The scale of the projects may vary, but the impact is always significant.  

For the last several decades, the city of Lino Lakes, just north of the Minneapolis-St. Paul metro, has been investing in their infrastructure across the community.  In the end, it’s not one single project that has helped to build a vibrant community, but rather the collective investment in varying infrastructure. These investments have played a vital role in spurring development and progress within the city.

1. Biological Water Treatment Plant

The city is currently planning to construct a water treatment plant due to some of the city wells having manganese levels above the recommended guidelines. A biological treatment approach is unique because it relies on natural microbial activity to remove contaminants rather than chemicals, an environmentally sustainable strategy.

2. West Shadow Lake Drive

West Shadow Lake Drive is a residential street that was plagued by potholes, had no sewer or water, and faced challenges from high groundwater levels due to its proximity to Reshanau Lake. As part of the city’s pavement management program, the road was removed and replaced to support the city’s roadway infrastructure and sanitary sewer, watermain and storm sewer infrastructure was also installed. In addition, environmental work and wetland enhancements occurred throughout the area.

3. 12th Avenue Trail Project

The 12th Avenue Trail connection was identified as a priority in the city’s Comprehensive Parks and Trails System Capital Improvement Plan due to the lack of trail connection along 12th Avenue.  Prior to project completion, the busy rural road was narrow with unsafe conditions for pedestrians and cyclists. The project resulted in increased safety and a more bikeable, accessible community.

4. Master Plan and Comprehensive Stormwater Management Plan

Located in the northeast corner of Lino Lakes is a 1300-acre greenfield area that is prime for development opportunities. WSB was contracted to develop a master plan, comprehensive stormwater management plan and update the Alternative Urban Areawide Review (AUAR) for the area. Development opportunities will include residential, industrial and commercial that will spur economic activity in the area. 

5. The Rookery Activity Center

When the local YMCA closed in 2020 it left a hole in the community. The city of Lino Lakes took action to reinvigorate the space. To establish itself as a new asset within the community, the building needed an overhaul, not just in amenities and programming, but also the brand.  WSB worked with the city to develop a story, identity and brand assets.

6. Tower Park  

Tower Park is located on a 60-acre piece of land that was purchased by the city over 20 years ago.  The city council felt strongly about developing the space into a destination recreation area for the community.  WSB provided the park master plan and phase 1 design support. Tower Park is now home to some of the city’s most popular pickleball and tennis courts.  The project was completed last year. 

7. Birch Street Roundabouts

Birch Street is a heavily traveled roadway through the city with frequent accidents occurring due to the number of entrances to the high-speed roadway.  There were safety concerns from residents and a nearby school. To help alleviate the number of accidents and increase safety, several roundabouts, medians, crosswalks and safety signage were added.

8. Gateways to the City – Placemaking

Lino Lakes is a proud community and wants to enhance their welcoming presence by creating placemaking monuments at city entrances. The project is still under development, but once complete, the entrances will offer a ‘front door’ to the city and will invite visitors and residents to step inside and explore the community.

9. Feasibility Study – Lake Amelia Subwatershed

A 255-acre subwatershed of Lake Amelia is currently undergoing a feasibility study to address existing stormwater management concerns and anticipated future land use changes to the area.  The short-term phase includes solutions to address flooding concerns.  The long-term phase proposes more holistic improvements to the corridor that that would occur alongside its eventual development. The study will help guide future planning in the area and will ensure that the area is prime for development.

10. Shenandoah Park Improvements

In partnership with the Rice Creek Watershed District, the city is exploring multiple improvements to the Shenandoah Park area to improve water quality, ensure its habitat is supported, and create a destination for park users. WSB is currently exploring water quality improvement options, wetland restoration, flood retention and greenway spaces to support the goals of the watershed district and the city.

Designing Drainage Systems for Renewable Energy Sites

By Dan Cazanacli, Project Manager, and Henry Meeker, Graduate Engineer, WSB

When designing drainage systems for renewable energy sites, many different surface water factors must be considered to ensure a well-constructed system. These factors include how floods can impact the site, how water damage affects equipment and access points, soil erosion, water regulations, and how runoff impacts the surrounding ecosystem.

Floods can cause both widespread and deep channelized flow across solar farms.

Designers need to understand how water will flow across the site in different flood scenarios. Many renewable energy sites are located near floodplains, which can make the design process even more complicated. To tackle these challenges, WSB engineers use sophisticated 2D hydraulic models to map the direction, depth, and speed of water flow across the site.

Stop water damage to critical site components.

A crucial part of the drainage systems design process is ensuring that water, in any scenario, can flow smoothly across the site without causing any damage or flooding to critical components, such as inverters or battery storage units. Designers use the results of the hydraulic models to find the best solutions for water flow and to place these critical components away from the main flow of water. The models are also used to identify areas where water flows too quickly. WSB develops erosion control measures in these situations, such as reinforcing road surfaces at low water crossings.

Plan for ground erosion around solar panel support piles.

Another important aspect of renewable energy site design is ensuring that the supports for the solar panels can withstand strong winds and flooding. Each site is unique, our engineers work closely with our clients to use the results of the hydraulic models to assess the potential scour depth, meaning the point in the ground where erosion could occur, around the support piles and identify the appropriate methodology to use. This determines the best depth for embedding them. The models can also be used to identify areas where water is flowing too quickly and to develop erosion control measures, such as rock stabilization.

Consider water quality and management regulations.

Designers also need to consider regulations around stormwater management, water quality, floodplains, wetlands, and critical species/habitats. Project timelines will be significantly delayed without proper planning and consideration of these factors. WSB works to minimize the impact of the site on these sensitive areas while ensuring that the project proceeds on schedule. This often involves working closely with local government units and obtaining the necessary permits.

Protect ecosystem health.

Designers must understand how solar panels interact with the surrounding vegetation and soil. Major institutions, like the University of Minnesota, are performing ongoing research into how panel runoff affects water infiltration and an ecosystem’s health that will be incorporated into designs. Designers can leverage these findings to optimize water quality benefits for the site, incorporating water quality basins, pollinator-friendly vegetation, and site-specific erosion control measures.

Snow Melt Offers an Opportunity to Improve Flood Management Systems

February 13, 2023
By Bill Alms, Project Manager, WSB

Since 2020 Minnesota has experienced drought conditions, with less than average rainfall. The five years before that, Minnesota faced several extremely wet years, and communities were more prone to flooding with average rainfall as much as a foot above average.

This winter, Minnesota has already received well above average snowfall, similar to the winter of 2019-2020. If snow melt trends stay similar this spring to the spring of 2020, it may offer communities a unique opportunity to measure flood storage capacity, identify underperforming outlets, and update flood resiliency plans based on real time data. 

Why This Spring May Provide the Perfect Test Case

Coming off of a wet summer and a snowy winter in the spring of 2020, many communities saw flood storage capacity at its limit. Numerous reservoirs and ponds were high or overflowing, and communities struggled with underperforming drainage outlets. 

Now, this year many of those basins and ponds are low due to ongoing drought and extremely dry conditions – the opposite of 2020. However, with similar snow melts expected in the spring of 2020 and our upcoming spring, this could be an opportunity to reexamine those stormwater basins and assumptions around storm events. 

In short, this may be a rare opportunity to compare real world outcomes with projected models in flood resiliency plans. 

Updating Flood Management Systems 

If outlets flood again this spring with similar snow melts, coming off drought conditions, it is an indication that flood capacity needs to be expanded or elevation increased. It may also indicate where underperforming outlets need to be redesigned or rethought to better reduce flood risk and protect infrastructure. 

Smart technology tools can help determine where to add more storage and how communities can do next step planning on flood mitigation. Communities can install pumps within storm basins, for example, in areas that need more flood storage.

Other Tools to Address Flood Risk During Spring Snow Melts

In addition to updating flood management systems this spring, communities should also ensure they are acting on current flood management plans and tools to prevent flooding and protect infrastructure. This includes zoning areas that need the most attention, educating residents on the importance of removing ice and snow at low points and ensuring storm drains are clear, sandbagging structures if necessary, pumping areas with poor drainage patterns, and more.
