Across the country, cities are facing growing challenges related to air and water pollution. Urban development, aging infrastructure, and climate change are intensifying the pressure on municipal systems. From stormwater runoff to vehicle emissions, the sources of pollution are varied and complex. Yet, cities have a unique opportunity to lead the way in environmental stewardship by adopting thoughtful, community-centered approaches. 

1. Invest in Green Infrastructure 

Green infrastructure such as rain gardens, permeable pavements, and vegetated swales can significantly reduce stormwater runoff and filter pollutants before they reach local waterways. These solutions not only improve water quality but also enhance urban aesthetics and biodiversity. 

2. Promote Sustainable Transportation 

Reducing reliance on fossil-fuel-powered vehicles is key to improving air quality and reducing air pollution. Cities can encourage walking, biking, and public transit through better infrastructure and incentives. Supporting the transition to electric vehicles and expanding charging networks also plays a vital role in lowering emissions. 

3. Modernize Wastewater and Stormwater Systems 

Outdated systems can leak contaminants into the environment. Upgrading pipes, treatment facilities, and monitoring technologies helps prevent overflows and ensures compliance with environmental regulations. Proactive maintenance and asset management are essential to long-term success. 

4. Use Data to Drive Decisions 

Environmental monitoring such as air and water quality sensors provides cities with the data needed to identify pollution sources and track improvements. Integrating this data into planning and operations enables smarter, more targeted interventions. 

5. Engage the Community 

Public education and engagement are powerful tools in pollution prevention. Cities can foster community involvement through outreach campaigns, school programs, and citizen science initiatives. When residents understand the impact of their actions, they’re more likely to support and participate in sustainability efforts. 

Cities have a critical role to play in protecting the environment and public health. By embracing innovative practices and engaging their communities, they can make meaningful progress toward cleaner air and water. WSB partners with municipalities to support these efforts bringing technical expertise, strategic planning, and a collaborative spirit to help cities achieve their environmental goals.

The countdown to the release of the updated MS4 Permit has begun. The current MS4 Permit for Minnesota communities will expire on November 15th, 2025. As a new permit expiration date approaches, it’s a good idea for communities to take a few minutes to reflect on MS4 progress made to date.

Here’s what communities can do now:

  1. Review and update storm sewer system maps. Take a close look at storm sewer, pond, outfall, and structural stormwater BMP locations and ownership information and complete updates, as needed.
  2. Dust off ordinances, written procedures, enforcement response procedures, form templates, and save them in a convenient location – they’ll come in handy for the Part II application.
  3. Complete a mock audit. Understanding the current state of the program compared to the existing requirements will better prepare communities for Part II of the application.
  4. Organize files and recordkeeping mechanisms. Consider creating a shared drive so everyone can help track and contribute to MS4 activities. If the current set-up isn’t working, now is the time to find a system that works for easy tracking for the next permit cycle.
  5. Continue the routine upkeep of your MS4 program to keep operations running smoothly, including staff training, erosion control inspections and enforcement, public education efforts, annual meetings, etc. The permit may be approaching expiration, but implementation of current programs and management of stormwater conveyance systems must main.   

WSB can help manage MS4 programs at every stage. With over a decade of experience supporting communities throughout Minnesota, the WSB team brings valuable expertise to MS4 management. Services include updating system maps, performing audits, and assisting with record keeping and overall program management. By addressing these tasks proactively, communities will be well-prepared to handle whatever the new MS4 Permit may require.

When severe weather strikes, taking swift and informed action is crucial to ensure safety and minimize storm risks. Being prepared and knowing how to respond effectively can make a significant difference.

Stay Indoors & Seek Shelter: During severe weather, it’s essential to follow your preparedness plan by sheltering in a designated safe space, such as a basement or an interior room without windows. If you’re in a public location, avoid large open rooms like gymnasiums and seek shelter away from windows and glass doors. For those caught outdoors, do not attempt to drive, especially in dangerous weather like tornadoes or flash floods. Instead, find sturdy shelter to reduce storm risks. Stay away from overpasses, trees, or other unsecured structures that could pose a risk. If no shelter is available, lie flat in a low-lying area while covering your head and neck.

Stay Alert & Informed: Staying informed during severe weather is critical to managing storm risks. Keep a charged cell phone and a backup battery handy. This ensures you can receive updates and stay connected. Invest in a NOAA Weather Radio to receive real-time emergency broadcasts, even if cellular networks fail. While social media and local emergency management pages can provide valuable updates, they should not be your sole source of information. This is due to the potential for misinformation or network outages. Ensure notifications for weather alerts are enabled on your phone to stay updated on warnings and advisories in your area.

Avoid Complacency: Severe weather often brings multiple alerts over time, leading to what’s commonly known as “weather fatigue.” This constant barrage of warnings can cause people to ignore subsequent alerts, assuming the danger has passed. However, severe weather patterns are unpredictable and can change rapidly, making it crucial to treat each warning seriously to mitigate storm risks. Always listen to official directives, even if the situation seems stable, as conditions can escalate without warning.

Aftermath & Recovery Resources: The aftermath of severe weather can be challenging and require time and effort to recover. Local Emergency Managers are often the first to provide assistance, helping with debris removal, temporary relief efforts, and damage reporting to state and federal agencies. Understanding storm risks is important because immediate assistance might not be available for up to 72 hours. This is because response teams mobilize resources. To facilitate quicker recovery, document all damage by taking photos and videos of your property before discarding any damaged items. These records, along with receipts for repairs or replacements, can be invaluable for insurance claims or applications for disaster assistance.

Beyond personal recovery, building community resilience is a vital part of preparedness. When individuals and families have a plan, and encourage others to develop their own, the entire community benefits. A resilient community can respond more effectively to crises, reduce storm risks, and recover more quickly. Preparedness extends beyond individual safety—it strengthens the bonds within neighborhoods and fosters a collective effort to face and overcome challenges together.

WSB Support for Communities: At WSB, we are dedicated to supporting communities not just in the aftermath of severe weather but also in preparation for it. We work to raise awareness about potential storm risks, provide resources to strengthen preparedness efforts, and assist in recovery. This helps individuals and neighborhoods rebuild stronger and safer. Together, we can create a culture of readiness and resilience, ensuring that no one faces these challenges alone.

Through various emergency relief and management efforts, our team leverages technical know-how and innovative solutions to promote safety and efficiency in the regions we serve from coast to coast.

From snow drifting management to environmental improvement efforts, WSB offers solutions that maintain the stability and resilience of infrastructure in the face of emergencies.

Snow Drifting Management

Engineering solutIONS for winter challenges

In regions prone to severe winter weather, snow drifting can bring entire transportation networks to a standstill. High winds push snow into drifts that can block highways, railways, and access roads, creating hazardous conditions for travelers and first responders. In addition to impacts to travel, snow drifting also increases maintenance and fuel costs for local departments of transportation.

To mitigate these effects in the Midwest, WSB utilizes advanced software to analyze snow drifts and wind, as well as design solutions, allowing our team to proactively identify and address problem areas. Using natural and synthetic snow fences, berms, and road designs that incorporate strategic cuts and embankments, our team works with departments of transportation to ensure that critical routes remain accessible during snowfall. This foresight eases the effect of winter’s harsh impacts and ensures safer roadways and cost savings for the community.

Hurricane Relief and Recovery

Building resilient communities

When hurricanes strike, they leave behind a trail of devastation: downed power lines, collapsed bridges, blocked roads, and more. Coastal communities are often the most at risk, necessitating a robust emergency response strategy. WSB works hand in hand with emergency response teams to prioritize restoration in hurricane-affected areas. Our team recently partnered with the Florida Department of Transportation (FDOT) to assist communities in Florida in recovering from the effects of Hurricanes Debby, Helene, and Milton. This included managing cut and toss operations, debris removal, and signals and generators, as well as electronically documenting roadway conditions using GIS technology, prioritizing the reopening of the most critical routes.

The aftermath of a hurricane demands rapid assessments of structural damage and the design of temporary solutions to reconnect communities to essential services. Civil engineers, though often overlooked as responders, play an important role in protecting communities against these natural disasters.

Environmental Investigation and Remediation

Protecting our future

In the chaos of an emergency, environmental risks often take a backseat to immediate recovery efforts. However, those specializing in environmental investigation and remediation know that focusing on these issues are key to long-term community recovery.

WSB’s Environmental Investigation and Remediation team plays a vital role in addressing environmental hazards. From encountering tanks and petroleum spills during roadway construction to providing structural assistance to the U.S. Post Offices in the upper Midwest related to fires or vehicle crashes, asbestos, and more, our team is dedicated to safeguarding public health by conducting comprehensive assessments and developing tailored solutions to mitigate risks. The team works closely with clients, such as DOTs and city agencies to report contamination to EPA associations while providing transparency and thorough investigation. Through these efforts, WSB demonstrates strength and versatility in emergency management. Our commitment to innovation and collaboration means that we’re always prepared to face new challenges and protect our communities.

Resident Problem Reporter

Ensuring safety and transparency through real-time communication

The use of salt as a deicing agent on roads has been a common practice for decades. However, it comes with significant drawbacks that cannot be overlooked. The corrosive nature of salt contributes to the deterioration of infrastructure such as bridges and roads, and vehicles, causing costly repairs and replacements. The runoff of salt after winter weather can have detrimental effects on the environment too, affecting vegetation, aquatic ecosystems, and wildlife. Rock salt has also proven to be less effective in single digit temperatures, or when temperatures dip below zero degrees. With these concerns in mind, city governments are increasingly exploring alternative solutions to ensure road safety during winter months.

One promising alternative is the use of beet juice, derived from the sugar beet. Increasingly recognized for its eco-friendly properties, beet juice significantly improves the efficacy of ice melting solutions when mixed with brine. The sugars in beet juice lower the freezing point of water more effectively than salt alone, allowing it to work even at lower temperatures. Its viscous nature helps the brine adhere better to road surfaces, reducing the need for frequent applications.

There are several advantages to using beet juice for deicing. Beet Juice is less corrosive than salt, aiding in the resiliency of city infrastructure such as bridges and roads. The use of beet juice in a deicer provides a range of benefits that make it a compelling alternative to the standard salt brine. While both methods are effective at melting ice, beet juice’s lower environmental impact and reduced infrastructure damage, paired with the enhanced performance in lower temperatures provide a strong case for its adoption and helps ensure safer roads even in the most severe winter conditions.

For city staff seeking proficient management of all aspects of road maintenance, WSB offers expert assistance and comprehensive pavement management planning. Our experienced team can help municipalities with deicing strategies, road repairs, and long-term infrastructure planning. With WSB’s support, cities can ensure their roads remain safe, functional, and sustainable throughout the winter months and beyond.

Meeting Traffic Demands and Environmental standards with aesthetic sensitivity

As with many instances of aging infrastructure, the bridge across the Snake River to the East of Pine City, MN reached a point in its lifespan where it needed to be redesigned and replaced. Construction projects like bridges require focused attention to a variety of elements to not only ensure the bridge is sound and long lasting, but also to ensure no concerns are created like blocking off access from boats or environmental concerns. The Snake River Bridge scheduled to be completed in the fall of 2024 provides a superb example of the many facets that make up bridge design.

Meeting Traffic Needs

One point of consideration for bridges are current and future traffic needs. Previously, if farm equipment needed to cross from both sides of the bridge there would be issues. With the newest designs, the addition of extra wide shoulders allows for traffic to flow whether by car or larger. Through traffic forecasting, a bridge design can meet the needs of the current levels of traffic and those estimated for up to 40 years of potential population growth in the area. This project’s analysis deemed additional lanes unnecessary so long as the extra wide shoulders were included. Ensuring the bridge is only as big as is needed will save considerable time and money.

Considering Environmental Data and Concerns

In bridge design, gathering hydraulic data about the river is imperative to ensure that not only will the bridge be able to handle expected seasonal water depths and the speed of the river’s flow, but also to ensure that any bridge design avoids negatively impacting the areas downstream. For example, the updated trail on either side of the bridge included designs for updated drainage ponds and piping to prevent the road and nearby residences from being affected during heavy rains.

When tearing down an existing bridge, care must be taken to ensure that the river is not polluted, and animal habitats are not unnecessarily impacted. Specifically for the Snake River project, remnants of an older bridge still remained and new designs included removal. For both environmental concerns and financial reasons, the Snake River Bridge was designed with the impetus of ensuring durability and expandability. Not only is the bridge made to last, but also if population growth surpasses estimates the bridge can be more easily expanded to fit the new needs rather than torn down and rebuilt again.

To meet environmental and safety concerns, plans for a path underneath the bridge were included in the design that will grant extra protection for drivers, pedestrians, and the local wildlife once the bridge is completed and put to use. Accessible paths allow for foot traffic of both people and animals to maneuver safely without needing to cross the street.

Reducing Costs

Steps were taken through data gathering and design to limit unnecessary costs. These aspects include adding contingencies in relation to the soil and bedrock. Through geotechnical data gathering, it was identified that there are high levels of bedrock close to the surface in the construction area. Building with bedrock is difficult and attention was given to include contingencies on how to handle different bedrock or soil conditions during construction to ensure the project does not stop and cost money and time. Additionally, to limit excess costs geotechnical data was able to be acquired by drilling through the old bridge and into the soil rather than using a barge. Using a barge for data gathering would have drastically increased costs.

A Completed Project With Aesthetic Appeal

Bridge designs like the one used for the Snake River Bridge meet the needs of the communities that use it, protect against environmental impacts to the water, soil and local animals, reduce costs, and provide a timetable to ensure the bridge will be constructed and reopened without delay. Even down to forgoing the usual plain rectangular shapes and including parabolic arches to for little additional funds to make the bridge more attractive and not stand out so much against the beautiful environment around it. Creating not only a finished usable bridge, but one that is attentive to the various needs of the community, the land it sits on, and the river it crosses are what bridge design is all about.

Carl is Director of Structures, and he brings a deep comprehension of MnDOT’s guidelines and protocols for bridge and transportation projects. His extensive experience includes leading studies, engaging with the public and stakeholders, assessing environmental impacts, and overseeing both preliminary and final design stages. Carl has a track record of designing over 70 bridges throughout Minnesota, along with a variety of other structures such as retaining walls, noise barriers, tunnels, and sign structures. His profound knowledge and proven expertise in structural design make him an essential leader, adept at guiding decisive actions and advancing significant projects.
