Sustainability continues to play a growing and evolving role in how communities plan, invest, and adapt. What was once considered a long-term goal is now also part of everyday decision-making at the local level, especially as communities look ahead to the next generation of comprehensive plans. 

Across Minnesota and beyond, local governments are finding meaningful ways to integrate sustainability into their work through the intersection of environmental, economic and social considerations. This includes updating ordinances to support EV infrastructure and renewable energy, taking advantage of cost-saving energy efficiency rebates, advancing climate adaptation and resiliency strategies, and reducing vehicle miles traveled and greenhouse gas emissions through long-range planning efforts like the Imagine 2050 Comprehensive Plan. 

At the same time, communities are balancing these priorities with growth, infrastructure needs, and resident expectations—making it essential to take a practical, tailored approach. Progress doesn’t have to be complex to be impactful. For some communities, it starts with policy updates or plan amendments. For others, it begins with conversations about priorities, tradeoffs, and what sustainability truly means at a local level. 

How We Can Help 

At WSB, we partner with communities to identify realistic, actionable steps that support long-term sustainability goals while reflecting each community’s unique character and vision. Whether it’s integrating new strategies into a comprehensive plan or exploring incremental changes over time, we focus on helping communities move forward in a way that fits their needs.

Roadway safety is often talked about in terms of driver behavior, but many of the most effective ways to reduce crashes start with everyday roadway design decisions. In day-to-day transportation planning and project delivery, safety improvements often come from practical choices built into routine projects. When safety is considered early, agencies can reduce both the number and severity of crashes while creating roadways that work better for everyone.

One of the biggest opportunities lies in speed management. Roadway layout, lane widths, and context sensitive speed limits all influence how fast people drive. Design features like narrow lanes, curb extensions, raised intersections, and other traffic calming measures help encourage safer speeds without relying solely on enforcement. When roadway design matches the surrounding land use, drivers naturally slow down and crashes become less severe.

Intersections and corridors also deserve special attention. Many crashes happen where traffic movements overlap or where vehicles interact with people walking or biking. Approaches such as roundabouts, improved turning layouts, more visible crosswalks, and separated pedestrian and bicycle facilities help reduce conflicts and make travel more predictable for all users.

Other roadway features quietly support safety every day. Elements like safety edges, rumble strips, better lighting, clear signage, and thoughtful access management help drivers stay oriented and reduce unnecessary conflict points. Together, these improvements create roadways that are more forgiving and better able to account for everyday mistakes.

Looking ahead, roadway safety continues to evolve as agencies adopt more proactive and data driven approaches. Rather than relying only on past crash data, communities are using real time information and systemwide tools to identify risks earlier. Technologies like adaptive signals and smart intersections are helping reduce conflicts in high-risk areas, while connected systems are beginning to provide real time alerts to drivers. Together, these efforts build on proven design strategies and reinforce a simple idea, safer outcomes happen when planning, data, and design work together.

WSB works with cities and states to bring these approaches into everyday transportation planning, design, and capital improvement programs. By using data to identify higher risk areas and applying proven safety strategies within routine projects, our teams help agencies stay ahead of safety challenges instead of reacting to them. From integrating new technologies to refining roadway design with a systemwide perspective, we support practical, cost-effective decisions that improve long term performance and protect the people who rely on these roads every day.

Published by League of Minnesota Cities in the May-June month’s issue of the Minnesota Cities Magazine. Protecting Communities from Utility Damage

Over the past six years, cities have seen unprecedented infrastructure build-out in the public right of way. Advances in technology and increased federal funding have fueled a nationwide telecommunications boom, and the COVID-19 pandemic further accelerated that growth as demand for reliable broadband surged. The public right of way includes city-owned land used for streets, sidewalks, and underground utilities. As telecommunications providers expand fiber and related infrastructure, more equipment is being installed in these shared spaces. That pressure is creating new challenges and unintended consequences for municipalities.

Growing strain on city systems

Public rights of way are increasingly overcrowded and accurate utility records are limited. At the same time, many cities have not established clear telecommunications design standards.

This combination can overwhelm permitting systems, and place inexperienced contractors in tight, complex environments. The risk of utility strikes increases, ranging from minor damage to serious gas and water incidents. Payment structures that reward speed over care can further elevate risk. The result may include safety concerns, strained emergency response resources, and higher municipal costs.

Strengthening permit review and coordination

Clear design guidelines are an important first step. Cities should require that plans submitted for permit review identify existing utilities and receive approval before construction begins. When required by the utility owner or municipality, plans should also include utility offsets or clearance requirements.

Municipalities should conduct a thorough review of submitted plans before issuing permits and designate a point of contact to coordinate with utility providers during the review process. Identifying conflicts early helps ensure compliance with established standards and reduces issues during construction.

Providers often seek to permit and construct multiple or large project areas at the same time. This approach can create unsafe conditions, such as open excavations left overnight, and allow poor restoration to go unaddressed if standards are not enforced.

Large projects place heavy demand on the 811 utility locating system, which helps identify and mark underground utilities before digging begins. When locating crews are stretched thin, some utilities may not be marked even if contractors follow the required process. Inspections also become more difficult when several companies are working in the same area at the same time.

In these situations, it can be unclear who is responsible for damage or unfinished restoration work. Residents may be left with disrupted boulevards or landscaping and little information about who is responsible. Complaints often end up being directed to city staff, which can create additional work and frustration.

Practical steps to reduce damage

Cities have a natural ally in private utility owners, including gas and electric providers. These stakeholders face many of the same challenges from the ongoing build-out and have invested significant resources to address them. Collaboration can lead to meaningful improvements, beginning with the permitting process.

In some jurisdictions, permit applications require mapping of existing facilities within the project scope as part of plan-and-profile utility permit submittals. Additionally, some municipalities incorporate bonding requirements into the permitting process, with bonds released only after the project area is fully or substantially restored.

Municipalities may cap permits based on the amount of footage they can reasonably manage with available resources. Refillable escrow accounts can help incentivize contractor performance. Some cities limit new permit issuance until project restoration is complete, supporting damage prevention and accountability.

Additional permit requirements that support coordination and damage prevention include:

  • Integrating Gopher State One Call language in permit applications. This reminds contractors of Minnesota’s excavation laws and their requirement to notify 811 before digging.
  • Requiring 811 notifications that reflect the size and scope of the project. This helps utility companies assign enough staff and resources to locate and mark underground utilities.
  • Requiring meet tickets to support ongoing project updates as construction progresses. Meet tickets are an 811 tool that facilitates communication between construction crews and locating stakeholders. Because large 811 project tickets may be difficult to mark within the 48-hour window — particularly in Minnesota, where projects exceeding 1 mile require a meet ticket — these tools can help reduce production delays and utility damages.

Impacts on emergency response

Natural gas companies and fire departments also benefit from a more coordinated approach. Fire departments are typically required to respond to all natural gas facility damage or leaks. Because standard gas facility depths often place lines in conflict with ongoing infrastructure build-out, response demands can increase during peak construction periods.

Working together to protect communities

Municipalities do not need to manage these challenges alone. Many utility providers are adopting improved technologies and damage-prevention practices. Through collaboration, cities and utility providers can establish clear standards and effective permitting and construction processes that protect infrastructure and reduce disruptions, safety risks, and costs.

Successful infrastructure delivery is defined not just by completion, but by how effectively a project is executed. Accelerated schedules, thoughtful planning, and the ability to adapt to changing field conditions all play a role. Projects that stay on track consistently balance efficient sequencing, strong coordination, and a commitment to quality and compliance. 

Today’s projects are increasingly complex, requiring alignment between contractors, agencies, utility owners, and stakeholders, often within tight timelines and active environments. Teams that identify challenges early and respond quickly are better positioned to maintain progress and avoid costly disruptions. 

Managing Complexity in Construction Execution 

Site constraints, utility conflicts, and the need to maintain ongoing operations create significant challenges during construction. Whether working in limited corridors or high-traffic areas, success depends on clear communication and coordinated execution. 

High-performing teams prioritize: 

  • Joint review and approval of design elements 
  • Coordinated access and staging strategies 
  • Ongoing compliance verification 
  • Regular communication through meetings and field reviews 

This level of coordination improves transparency, speeds up decision-making, and helps resolve issues before they impact schedule or cost. 

Utility Coordination as a Critical Path Driver 

Utility conflicts remain one of the leading causes of delays in infrastructure projects. Early coordination is essential to maintaining production and avoiding rework. 

Effective strategies include: 

  • Verifying existing conditions early 
  • Identifying conflicts in advance 
  • Developing phased relocation plans 
  • Coordinating access within right-of-way constraints 
  • Scheduling protection measures to maintain service 

When utility owners and project teams align early, construction can move forward with fewer interruptions and greater confidence. 

Proactive Risk Management and Adaptive Sequencing 

Unforeseen conditions and constraints are inevitable. What sets successful teams apart is how they respond. 

Flexible execution strategies may include: 

  • Opening multiple work fronts 
  • Shifting sequencing to maintain productivity 
  • Adjusting resource allocation 
  • Accelerating procurement when needed 

Maintaining flexibility in sequencing helps preserve momentum and protects critical schedule milestones without relying solely on increased manpower. 

Quality Control and Material Compliance 

Consistent quality management is essential, especially on projects involving multiple stakeholders and regulatory requirements. 

Strong quality programs focus on: 

  • Verifying materials and suppliers 
  • Coordinating testing and inspections 
  • Maintaining clear documentation and traceability 

Proactive coordination with suppliers and agencies helps avoid delays from rejected materials or missed approvals, while also streamlining project closeout. 

Documentation and Progress Monitoring 

Clear documentation and real-time visibility into project performance are critical to maintaining control. 

Effective teams: 

  • Maintain organized, accessible project records 
  • Track progress against schedule and production targets 
  • Adjust resources and sequencing based on real-time data 

This approach enables faster issue resolution, improved accountability, and better alignment between planned and actual performance. 

Collaboration Drives Successful Outcomes 

At its core, successful project delivery is built on collaboration. When contractors, agencies, utility providers, and stakeholders work as an integrated team, they can address challenges more efficiently and maintain consistent progress. 

Projects that prioritize communication, coordination, and shared accountability are better equipped to: 

  • Navigate constraints and access challenges 
  • Resolve conflicts quickly 
  • Maintain quality and compliance 
  • Keep projects on schedule

The U.S. Department of Energy’s Unleashing Tribal Energy Development program is a national funding opportunity designed to support Tribal led energy planning and development aligned with long term priorities, governance structures, and operational realities. With approximately $50 million available, the program supports community-scale energy projects, feasibility and planning efforts, and large-scale initiatives tied to economic development. Applications are due July 24, 2026.

While this is a significant opportunity, Tribal energy development requires a thoughtful approach. Energy decisions often intersect with sovereignty, land status, utility coordination, workforce capacity, and long-term ownership. These considerations make it essential to view funding as part of a broader strategy rather than a standalone project.

In many cases, successful projects begin with planning and feasibility work. Tribes vary widely in infrastructure and governance, and interest in funding does not always mean readiness to pursue construction. A measured approach that prioritizes assessments and long-term planning can help ensure projects are sustainable and aligned with community goals.

Effective engagement starts with listening. Conversations should focus on understanding priorities, capacity, and long-term needs before identifying specific technologies or timelines. This creates space for solutions that reflect Tribal values and real-world conditions.

Through our work with Tribal Nations, we support energy planning, feasibility analysis, and project development by helping evaluate readiness, define practical scopes, and align opportunities with federal requirements. As the deadline approaches, thoughtful preparation can help ensure applications are both competitive and grounded in long term success.

Ultimately, this program provides an opportunity not only to advance individual projects, but to strengthen Tribal energy strategies, build capacity, and support long-term energy independence.

One of the clearest signals in the FY26 SS4A program is the increased emphasis on coordination. Improving roadway safety at scale requires more than funding awareness or technical design—it requires alignment across leadership, planning, engineering, public engagement, and long‑term implementation.

Alignment Across Disciplines Is Now an Evaluation Factor

From our combined perspectives, SS4A succeeds when no single discipline operates in isolation.

  • Grants and funding teams help ensure applications are grounded in defensible data, realistic scopes, and long‑term delivery considerations.
  • Planning and engineering teams identify systemic risk, apply the Safe System Approach, and prioritize strategies that balance urgency, equity, and feasibility.
  • Public engagement teams ensure local voices inform priorities, lived experience strengthens technical analysis, and trust is built early—especially in underserved communities.

These roles are distinct, but deeply interdependent. When one is underdeveloped, even well‑funded SS4A efforts can struggle.

Why Timing Matters More Than Ever

The FY26 deadline arrives quickly, but strong preparation takes time. Early coordination allows communities to:

  • Validate multi‑year crash and roadway data
  • Inventory existing plans and prior safety work
  • Align leadership direction with technical assumptions
  • Think realistically about implementation and reporting

Communities that start these conversations early often find they are better prepared, more aligned, and more strategic—regardless of whether they apply in the current cycle.

A Help‑First Starting Point

SS4A is flexible, but not one‑size‑fits‑all. Some communities are ready for implementation. Others are still building foundational plans. The most productive starting point is rarely a scope or proposal—it is a cross‑disciplinary conversation about priorities, data, capacity, and long‑term outcomes.

In FY26 and beyond, that preparation may matter more than any single application.

The FY26 Safe Streets and Roads for All (SS4A) Notice of Funding Opportunity signals a clear shift in how USDOT is evaluating applications. As the program enters its fifth year, communities are no longer assessed solely on interest or intent, but on readiness to deliver safety outcomes over time.

How SS4A Has Changed

Early SS4A cycles focused heavily on plan development. In FY26, expectations are higher. Applicants are increasingly asked not just what they want to do, but how they will implement, sustain, and report on safety investments.

From a grants and funding perspective, the most competitive applications consistently demonstrate:

  • A clearly defined safety problem supported by defensible data
  • Leadership commitment beyond the application cycle
  • Realistic scopes aligned with staff and delivery capacity
  • Understanding of post‑award compliance and long‑term stewardship

The Role of the Safety Action Plan Today

Comprehensive Safety Action Plans are no longer treated as static deliverables. USDOT is looking for plans that function as decision‑making frameworks.

Strong plans:

  • Explain why crashes occur, not just where
  • Show how strategies were evaluated and prioritized
  • Demonstrate readiness to move from planning to implementation
  • Align safety investments with broader transportation and community goals

Communities that treat their Safety Action Plan as a living document are better positioned for both current and future SS4A funding.

Early Preparation Still Pays Off

Competitive SS4A preparation cannot be rushed. Communities that begin early—by validating data, coordinating internally, and aligning leadership expectations—often benefit even if they do not apply in a given cycle.

In FY26 and beyond, readiness and coordination increasingly matter as much as the application itself.

Celebrated worldwide, Earth Day and the month of April encourage us to reflect on our role in protecting the natural world. As threats from natural hazards, habitat loss, and pollution grow, nature-based solutions emerge as innovative approaches that work in tandem with conventional strategies in favor of the environment. These approaches connect the restorative and protective abilities of ecosystems, offering sustainable solutions to challenges faced by both coastal and inland systems.

Coastal Ecosystems: The Front Lines of Climate Action

Coastal areas, including mangrove forests, tidal marshes, and coral reefs, play an important role in safeguarding the boundary between land and sea. These ecosystems are vital for mitigating the effects of rising sea levels, storm surges, and coastal erosion. For example, mangroves act as natural barriers, absorbing wave energy and reducing the impact of storms on coastal communities. Their natural structure also provides habitat for fish and other marine life, supporting biodiversity and local fisheries.

Nature-based solutions in coastal regions include restoring dunes, protecting mangrove forests, implementing living shorelines, and rehabilitating coral reefs. Such efforts not only preserve habitats and wildlife, but also enhance tourism, fisheries, and livelihoods. Combining natural infrastructure with grey infrastructure, such as living shorelines alongside concrete sea walls, helps improve resilience against climate extremes while preserving the landscape and sustainability of coastal environments.

Inland Ecosystems

Inland ecosystems encompass a variety of systems such as forests, wetlands, rivers, grasslands, and agricultural lands. These landscapes offer a variety of benefits to people and serve as habitats for many species, playing a vital role in ecological health. Forests help by absorbing carbon dioxide and releasing oxygen, which is essential for life. Wetlands act as natural barriers, absorbing excess rainwater and reducing the risk of flooding. Grasslands support pollinators and help keep soils stable, preventing erosion and supporting soil fertility.

Reforestation projects, wetland restoration, and regenerative agriculture represent nature-based solutions implemented within inland regions. These approaches protect, restore, and manage natural ecosystems to address a range of environmental hazards and challenges, contributing to human well-being, biodiversity, improved water quality, and enabling these systems to adapt to future climate risks. By incorporating these practices, communities enhance resilience, promote biodiversity, and maintain food security.

Collaboration and Innovation for a Sustainable Future

Effective nature-based solutions implementation requires collaborative efforts among governments, scientists, private sector, local communities, landowners, and real state professionals. Identifying restoration goals, prioritizing areas, conducting long-term monitoring, and openly sharing information, will support the successful implementation of these strategies to address local needs and encourage broad support.

Innovative policy frameworks and cross-sectors partnerships can help leverage resources and expertise to advance scalable projects that protect both people and the environment. Education and outreach further strengthen these efforts by encouraging individuals to get involved whether by restoring a riverbank, planting native trees or supporting sustainable production.

Earth Month reminds us of our connection to the natural world. By embracing nature-based solutions within our ecosystems, we protect the future of our planet. Let us celebrate Earth Month as an opportunity to reflect and take action to care for, restore, and support the landscapes that sustain us and future generations.

As communities across the country work to address climate change, the challenge is no longer setting ambitious goals—it’s turning those goals into practical, actionable plans. Effective climate planning starts with a clear, data‑driven understanding of a community’s emissions, risks, and priorities—and that’s exactly how WSB approaches every project. Drawing from industry best practices, we begin by establishing a strong foundation: developing greenhouse gas inventories, identifying climate vulnerabilities, and aligning goals with state and regional targets. This analytical groundwork ensures that climate strategies are rooted in real conditions, not assumptions, and sets communities up to make informed, high-impact decisions. This approach has been successfully applied in local communities like Mahtomedi, St. Anthony Village, and Circle Pines, where WSB has supported the development of tailored, actionable climate and sustainability plans.

But data alone doesn’t create meaningful change – people do. WSB places a strong emphasis on intentional, right-sized engagement that brings residents, businesses, and stakeholders into the process in a way that is accessible and actionable. Transparent, inclusive engagement improves outcomes and builds long-term support for implementation, and we tailor our approach to meet each community where they are. Whether through targeted surveys, stakeholder workshops, or focused conversations, we ensure that local knowledge and priorities directly shape the plan, without overburdening staff or budgets.

Finally, WSB’s climate plans are designed to move beyond vision into implementation. We integrate climate strategies into existing city processes, like capital improvement planning, policy updates, and infrastructure investments, so sustainability becomes part of everyday decision-making, not a standalone effort. By pairing technical expertise with practical, community-focused solutions, we deliver plans that are not only ambitious, but achievable, helping communities take meaningful steps toward a more resilient, low-carbon future this Earth Day and beyond.

For decades, cities measured transportation performance using a narrow set of indicators, including vehicle counts, travel times, and pavement conditions. But as urban areas grapple with changing climate conditions, equitable demands, aging infrastructure, and constrained budgets, a more sophisticated question has emerged: Is our transportation system actually working for people, the environment, and the economy all at once? Transportation Sustainability Assessments (TSAs) attempt to answer exactly that.

What Transportation Sustainability Assessments Measure and Why It Matters

At their core, Transportation Sustainability Assessments evaluate a transportation system across three interconnected dimensions: environmental performance, social equity, and economic viability. Rather than asking only how fast vehicles can move through a corridor, a TSA asks harder questions about who has access, what the system emits, who bears the burden of its impacts, and whether the investment is viable over the long term. A 2021 systematic review published in Transport Reviews examined 99 peer reviewed studies and identified nearly 2,400 unique sustainability indicators in use across the field, a figure that speaks both to the richness of the concept and to the challenge of standardizing it.

Common Methods Cities Use to Measure Transportation Sustainability

The most common assessment approaches fall into several broad categories, each offering distinct value to practitioners. Indicator and framework development is the most widely used method, characterizing nearly a third of published assessments, and produces structured tools that cities can apply to evaluate and report on their transportation systems over time. Multiple Criteria Decision Analysis is particularly valuable when a city needs to compare alternative investments or policies, using weighted sustainability criteria and stakeholder input to generate ranked, defensible priorities. Modeling and simulation tools allow cities to project the sustainability impacts of future decisions before committing capital, comparing outcomes such as the long-term emissions reduction of a transit investment against roadway expansion. The most advanced assessments identified in the literature were those that paired quantitative performance data with genuine community engagement, incorporating the perspectives of residents whose lived experience of the transportation system may differ significantly from what the data alone reveals.

How Transportation Sustainability Assessments Support Smarter, More Equitable Infrastructure Decisions

For smaller and mid-sized cities navigating complex transportation contexts, including industrial freight corridors, environmental justice communities, and limited staff capacity, the practical lesson from the literature is clear: start with a framework grounded in local policy goals, invest meaningfully in stakeholder engagement, and resist the temptation to default to easy-to-measure indicators at the expense of qualitative dimensions. When done well, a Transportation Sustainability Assessment establishes a measurable baseline that enables long term accountability, allowing cities to track progress against adopted sustainability goals and demonstrate outcomes to funders, policymakers, and the communities they serve. A TSA can transform transportation planning from a technical exercise into a genuine act of community investment, one that ensures infrastructure decisions reflect the specific conditions, values, and priorities of the people a city exists to serve.
