How Rethinking Asset Management Can Build a Smarter City

February 13, 2023

Infrastructure assets are not something we think about often, but we rely on them in our everyday lives, so it’s important we get the most out of them. When community leaders think about how to make their cities smarter, they often don’t think broadly enough. Leaders need to expand their thinking from an operations-centric perspective to thinking about how they maintain the assets themselves. 

When creating the smart city of tomorrow, there are numerous opportunities to integrate systems so that assets are better understood, better preserved, and better utilized. It means harnessing the power of digitization and predictive modeling, from major assets like roads and bridges, to smaller assets like streetlights and playground equipment. 

Here are some ways that community leaders can build asset management into their smart city planning. 

Ensure Smart Tools are Integrated When Managing Replacing Infrastructure 

Many of our major assets are aging and no longer able to be fixed and maintained with a band-aid approach. When replacing or upgrading assets, city leaders must ensure they are using the latest software and tools that allow them to better monitor assets and predict when they will need repairs. Enterprise Asset Management Systems (EAMS) provide digital tools that allow communities to coordinate all of their asset management from a wholistic, cross-asset trade-off approach. Digital integration also ensures better communication among all city departments and leaders – from the person on the ground making repairs, to engineers, to the city official making long-term financial decisions. 

Integrating digital management tools into community assets can also help cities strategically rethink capital planning over 10, 20 and 30 years. Making the digital transition in how you manage ensures that you are not just being reactive, but proactive in asset management. Moreover, it also ensures that knowledge about asset management is institutional and not lost as workers retire or move to different positions. 

Understand How Smart Asset Management Mitigates Risk 

Community leaders need to think about risk in two ways: the risk of an asset itself and the risk of an entire system of assets. Think about it as a pipe in a whole network of pipes. When one pipe breaks down it can impact the entire system of pipes. Better understanding when one piece of the whole will need to be updated or receive maintenance ensures a more efficient overall system, and better protects assets. 

Additionally, climate change also plays a significant role in asset risk. Many systems were built decades ago, using models and assumptions that no longer work as we face more major storms and weather events. Smart city tools reduce risk and protect assets like storm water systems. 

Think About Long-Term Savings 

For many leaders, adopting new technologies or implementing smart city policies can feel financially overwhelming, but there are numerous long-term benefits and cost savings. Predictive modeling can better manage and preserve assets, providing savings over the long-term while reducing unexpected costs. Resources and staff time are also better utilized.

Additionally, smart asset management reduces liability, risks, and improves community safety. When managing critical but often overlooked assets like sidewalks and crosswalks, for example, there are digital trails of maintenance and asset management plans. Not only is liability reduced, but city budgets, residents, and taxpayers are better protected too. 

Smart Asset Management Helps Humans Be Human

Relying on humans to know everything when it comes to asset management is unrealistic. There are so many variables and details that smart tools can predict and better manage. Rethinking asset management ensures that cities are managing all their assets in ways that are efficient, predictive, risk mitigation, and better serve residents. 

Not sure where to start, or unsure of the best ways to integrate asset management into your smart city planning? WSB can help your community integrate smart technologies and tools to better manage your assets.

The Benefits of Data Driven Pavement Maintenance

March 3, 2023

Did you know that the most effective way to manage pavement maintenance in your system is to plan five to ten years in advance? Many municipalities are forced into reactionary pavement maintenance projects. In these cases, decision makers are forced to spend their budgets repairing roads in the worst condition creating large, costly projects. This prevents resources from being allocated towards cost-effective treatments that focus on keeping pavements in good condition before they fail. To get ahead of reactionary maintenance and plan a roadway budget that maximizes the cost-effectiveness of each dollar spent, there needs to be accurate data on the condition of each pavement segment within a system. This provides the necessary information for a data driven pavement management and capital improvement plan to be implemented. Having a pavement network inspection done on a regular basis can bring clarity to condition trends, identify maintenance issues, and allow decision makers to be confident they are implementing the best possible pavement fix at the appropriate time.

Why is this important?

With all of the environmental factors and traffic loads that pavements are exposed to on a daily basis, deterioration is inevitable. With newer or better pavement, only a few distresses may be present so repair costs are lower. However, as pavements age their deterioration continues at an increasing rate. These damaged pavements are more expensive to maintain and may even require major rehabilitation. Knowing the current age, condition, and maintenance history for a pavement section can help determine the most cost effective fix for it based on where it is in its life cycle. Systematic pavement evaluations are one tool network managers can use to monitor their pavement and make the best use of maintenance and construction budgets.

What are pavement inspections and what do they do?

Pavement inspections provide scientific data about the existing conditions of a network of asphalt or concrete surfaces. The process involves a trained inspector evaluating the pavement and cataloging all distress by size, quantity, and severity. With this data, an overall Pavement Condition Index (PCI) can be calculated. This PCI number is a single value that is used to grade the condition of each pavement segment. From there, a report that contains analysis on the condition of the network and a series of recommended solutions for any deficiencies is generated. Additionally, the report may contain specific maintenance recommendations for each road, budget recommendations, trends in pavement conditions, and ideas on how to stretch a limited pavement budget to maximize the overall system condition.

What is the value of a pavement inspection?

A pavement inspection report is a key tool for decision makers to use when determining capital improvement plans and setting budgets. It provides data and rationale to support funding decisions on projects that can be shared with interested parties. The systematic method of determining roadway conditions ensures the most cost-effective and critical projects are being planned for without guessing or relying on personal opinions. In most cases, the cost of implementing pavement inspections pays for itself by optimizing the time and location of pavement repairs. Additional cost savings can be realized when planning the projects 5-10 years out so that similar projects types can be group into larger more cost effective projects.

Protecting the Endangered Northern Long-Eared Bat: What It Could Mean for Your Project

March 13, 2023

Northern long-eared bats are suffering significant population declines due to a number of factors including white-nose syndrome and summer and winter habitat loss. As a result, the U.S. Fish and Wildlife Service (USFWS) recently changed the status of the northern long-eared bat from federally threatened to endangered. The change will go into effect on March 31, 2023. Projects that may impact individual northern long-eared bats or their habitat will no longer be protected under the 4(d) Rule. These impacts include tree removal and collisions with wind turbines.

The full extent of how this new endangered designation will affect project schedules or project feasibility is still unknown. However, before the status change takes effect and the USFWS releases the new northern long-eared bat determination key, there are some key items to consider. 

What projects will be affected?

This change will apply to all projects within the northern long-eared bat’s range. If your project received a “No Effect” or “Not Likely to Affect” determination from the USFWS, it is still valid under the new restrictions. However, if your project received a “Likely to Adversely Affect” determination, coordination with the USFWS will have to be re-initiated. 

Suitable habitat of the northern long-eared bat includes trees that have cavities, sloughing bark, and deep crevices. Additionally, trees that are three inches or more in diameter at approximately chest height are potentially suitable habitats. Furthermore, individual trees can be considered suitable habitat if they are within 1000 feet of another suitable habitat. Understanding the habitat suitability of your project area is essential to follow USFWS guidelines and to avoid and minimize the risk of northern long-eared bat take.

So, what does this mean for my project?

The new implications of the status change will likely result in stricter windows and thresholds for tree removal. Northern long-eared bat surveys such as habitat assessments, presence/probable absence surveys, and emergence surveys may be required before tree removal or the construction of wind farms. There may also be mandated requirements and mitigation efforts for project-specific incidental take permits or habitat conservation plans. Projects may also need to further coordinate with the USFWS based on the results of the determination key.

Not sure of how this new designation will impact your project or where to start? 

At WSB, we conduct northern long-eared bat habitat assessments and surveys, complete incidental take permit applications, and develop habitat conservation plans to help your project move forward as smoothly as possible, while meeting the USFWS requirements. 

How Smart Cities Can Help Leaders Rethink Housing

March 13, 2023
Lori Johnson, Sr Professional Community Planner, WSB

From phone apps for garage doors and heating systems to new security tools like Ring doorbells, we use technology in our homes to make our lives easier. Now cities are also using technology in housing decisions to make the lives of residents better and improve their communities.

Smart city tools and data are key when cities think about housing, including when it comes to making constructive decisions, building homes, and identifying the greatest needs for community housing. 

Here are some ways cities are getting smart about housing. 

A Different Approach to Building Permits 

Until recently, builders were sending in paper copies of everything they needed to obtain building permits. Architectural plans and site plans were required, and they often came into building departments on large paper rolls. Inspectors and planners were using paper plans to review for code compliance and very often had to move these large plans from office to office. Now, technology is making this process smarter, more accessible, more efficient, and eco-friendly. 

There are several tech applications that cities can take advantage of for building permit issuance such as iMS and eTRAKiT. All building permits can be issued online, and everything is submitted and paid for electronically. The automation and productivity of issuing online building permits makes it faster and easier for builders to get started on homes – saving time and money.

Data-Driven Decision Making

With the use of online applications for building permit issuance, it also allows cities to collect information to make data-driven decisions. This means having access to information on home prices, location, types of construction, etc. 

Additionally, this data can be mapped to see where there are deficiencies in certain types of housing and resources. From that, communities can identify where there is a need for additional affordable housing, what types of housing are needed in different neighborhoods or regions, and make future investment and resource allocation decisions. Moreover, as affordable housing is a need in most communities, smart tools and data are essential to help resolve critical shortages. 

It’s not just city leaders that benefit from smart tools, but residents too. Technology allows homeowners and buyers to easily research addresses for past building permits, so they know what has been done to their home and when. There are also advantages when it comes to shopping for mortgages, allowing consumers to make educated purchase and remodeling decisions. 

The Building Process in 3D

Smart technologies are also affecting the way new homes are constructed. Some modular home builders use 3D modeling to generate home plans. Builders can then create modular homes in temperature-controlled environments at a faster pace than regular home construction and with less physical labor. It also helps eliminate barriers like being able to build in snowy, cold climates for instance. This is making home building more affordable and efficient. 

For city planners, the use of 3D modeling also comes into play when envisioning new housing types within communities. When planners are able to virtually see what the built environment will look like, they can make better recommendations to the community.

Looking Toward the Future

Integrating smart tools and tech into community building and planning allows cities to make smarter decisions. It can help identify and solve problems, tackle affordable housing shortages, and make processes more efficient and effective for builders and residents alike. 

It is important to remember that the term “smart cities” does not always mean that all citizens need to use technology to make their built environments better. But it does mean that it helps decision makers make smart decisions and smarter cities. WSB has many ideas and resources available to help cities be a part of this smart city evolution. If you have questions, we are always here to help you plan for and implement smart city technologies.

Six Things You Didn’t Know About Traffic Signals

March 13, 2023
By Sean Delmore, Director of Traffic, WSB

Traffic signals are an often-overlooked aspect of everyday life. But when you stop at a traffic signal, did you ever also stop and think about how, where, and why these signals are used? Here are six things you may not know about traffic signals.  

When is a traffic signal needed?

Communities thoughtfully decide where traffic signals are needed vs. roundabouts or stop signs. An Intersection Control Evaluation (ICE) is conducted to determine the appropriate method of traffic control, which includes a detailed signal warrant analysis. These studies measure the existing vehicular and non-motorized (pedestrian/bicycle) traffic volumes and evaluate crash history at the intersection. WSB traffic experts conduct these evaluations in partnership with communities and local governments to collect the necessary data and determine if a signal would help improve the traffic safety and operations of the area. 

Traffic signals are typically designed to last more than 20 years with routine maintenance and designed to handle forecasted traffic volumes 20 years out. The federal government has requirements that must be followed when planning for the installation of new signals. These requirements include signal warrants that are found in the Manual on Uniform Traffic Control Devices (MUTCD). 

What are the benefits of a traffic signal?

Efficiency and safety are the top benefits of traffic signals. Signals are designed to keep up the progression of heavy traffic while ensuring there are no undue delays to side streets. The signals imitate elements of human decision-making, such as when a pedestrian should cross a busy intersection or when it is safe for a vehicle to make a left turn. Removing that decision from the person and incorporating it into an automated system like the traffic signal increases the overall safety for vehicles and pedestrians.

The ability to efficiently manage traffic flow can also be a significant factor in the success of local businesses and the livability of an area for families. For instance, access management developed by signals reduces the chaos of vehicles entering and existing businesses onto the main corridor.

How do traffic signals communicate with emergency vehicles? 

Traffic signals can change to the green phase for emergency vehicles allowing them to respond quickly and safely to incidents. Most emergency vehicles have an emitter on the dashboard that communicates with the traffic signal to safely end an opposing signal phase and bring up a green indication for the emergency vehicle. The technology also will extend the length of a green cycle if it is currently green for the direction an emergency vehicle is travelling.

Why do traffic signals always turn red for me?

Despite what we sometimes think, not all traffic signals turn red as you approach— in fact, it is just the opposite. Traffic signals have “dilemma zone protection,” which extends the length of a green light when a vehicle passes the back detection as it approaches the light. This keeps the light green to eliminate the human dilemma of whether to speed up or stop when the light turns yellow. 

Additionally, sensors in the ground at the intersection detect cars as they approach. For example, in many signalized locations, a minor street with lower vehicle volumes won’t change to green unless a vehicle is waiting at the red light to maximize the efficiency of the major roadway. 

What’s the latest innovation with traffic signals?

Flashing yellow arrows are one of the latest innovations in traffic signals. The flashing yellow arrow allows the driver to decide when it is appropriate to turn left, as opposed to controlling left-turns with green and red arrows. This feature on signals may also change based on the time of day. For example, the flashing yellow left turn arrow may be used on a Sunday night when traffic volumes are significantly lower. Then, during Monday morning rush hour, when traffic volumes increase substantially, the flashing yellow arrow will not be utilized, and the signal can offer a protected only phase because there is too great a risk posed to left turning vehicles trying to find an acceptable gap against the amount of oncoming traffic.  

What’s on the horizon for traffic signals?

One element of future traffic signals being considered more and more in major metropolitan areas is incorporating pedestrians and cyclists into the signal system. Engineers are rethinking classic intersection designs to incorporate new technology such as Audible Pedestrian Signals (APS) & ADA compliant curb ramp improvements, as well as bicycle markings for improving safety and accessibility for all modes.

Designing Drainage Systems for Renewable Energy Sites

By Henry Meeker, Senior 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.

How WSB Can Help

Do you need help planning your solar project and navigating challenges around drainage water systems? WSB can help with your design, develop erosion control models, ensure protection of local ecosystems through sustainable solutions, and more.

How Cities Can Prepare for the EPA’s New Proposed PFAS Regulations

April 17, 2023
By Jon Christensen, Professional Engineer and Steve Nelson, Director, Water/Wastewater, WSB

The U.S. Environmental Protection Agency (EPA) has proposed establishing legally enforceable levels for six man-made Per- and Polyfluoroalkyl Substances (PFAS) that are known to exist in the environment and drinking water. The EPA’s proposed levels are below most states current guidance levels and are near the detectable limits of the particular PFAS compounds. This move represents a significant step forward in safeguarding the health of our communities. To achieve this goal, the EPA is leveraging the most recent scientific data and building on existing state efforts to limit PFAS, aiming to provide a nationwide, health-protective standard for these specific substances in drinking water.

PFAS compounds are being detected in more and more water sources, both in surface water and groundwater systems. It is essential that cities stay up to date on this rapidly evolving science, so they can be prepared to adapt to new regulations and rules as they are decided.

Here’s what you should do now to be prepared and the potential solutions if these PFAS compounds are identified in your city’s drinking water.

Testing for PFAS

Many cities are not currently monitoring or testing for PFAS compounds in their water systems. The proposed EPA PFAS regulations lower the acceptable amount of PFAS compounds, which will likely affect a greater number of cities. That’s why cities should begin testing now. Keep in mind that the Minnesota Department of Health has a web tool that cities can use to determine whether testing has already been done in their area. If no testing has been done, cities should consider testing and eventually will be required to conduct testing, and if regulated PFAS elements are detected above allowable levels, then cities must begin evaluating and implementing solutions.

Solutions for PFAS Contamination

There are several options for addressing identified PFAS that include obtaining water from a source or system that does not contain PFAS, blending water from multiple sources to dilute the amount of PFAS entering the distribution system, or treating the raw water that contains PFAS. The cost of addressing PFAS in the water supply will vary depending on the amount of PFAS detected and the solution type that is most feasible for that community.

How WSB Can Help

Thinking through the next steps now, while communities await the EPA’s final ruling on PFAS regulations, can set a community up for success and better prepare cities for evolving water quality regulations.
