Solar Utility Micro-Grading

By Jeff Sandberg, Sr. Project Manager, WSB

WSB’s Renewable Energy Solar team continues to innovate in the industry and expand our expertise. Most recently we developed a system to quickly and efficiently analyze and compare solar site grading costs. Even a 6” cut or fill across a large site can result in substantial costs making a site less attractive, or impractical, for a developer. Analyzing rows and rows of solar panels conventionally has been tedious and time consuming. Our new, automated CAD processes makes the analysis more efficient and cost-effective.

Methodology

The automated processes uses Civil3D. It allows the user to input tolerances from different panel types and desired racking lengths to generate a proposed grading surface. The system produces a thematic mapping of grading cut and fill quantities for areas within the array footprint on a micro level.

Analysis & Results

As solar developers know, site grading costs can make or break a project. Being able to quickly and efficiently apply this technology to small and large sites allows a developer to compare, evaluate and determine which sites are most cost-effective from a grading standpoint. We can further refine array layouts to efficiently and cost-effectively fit within the site terrain, minimizing the amount of site grading required.

Similar technology takes structural pile plans and produces a plan and point file of X, Y, and Z coordinates. That information can be downloaded to the surveyor, in the field, to pinpoint the exact location and elevation of each individual pile in a project, anything from 1 MWac sites to 500 MWac sites and larger. 

Geography

As a national company, WSB can apply this process to any site around the country. Our Renewable Energy team has worked on renewable energy projects across the country and can provide a full set of services for solar projects; services include, but are not limited to, Critical Issues Analysis (CIA), Engineering and Site Planning Approvals, Construction Surveying, and Geotechnical Services.

What’s next?

WSB continues to develop techniques and solutions to ensure the success of client projects. From Site Selection software to automated Micro-Grading Analysis, WSB continues to innovate and lead the Renewables market.

Top 5 first quarter best practices for city managers & administrators

By Bart Fischer, Senior Public Administrator, WSB

As New Year’s Day begins to fade and we launch full steam into 2020, I take the opportunity to reflect on my time as a City Administrator in cities both large and small as well as discuss with colleagues those things administrators & managers should be mindful of at the start of each year.  The following are five areas of importance that municipal executives should consider.

Strategic & Comprehensive Plan

Most organizations have a strategic or comprehensive plan.  These can be extensive and far reaching with a mission, values, goals, and implementation strategies set by the council, board, staff, and strategic stakeholders, or they can simply be a short list of priorities the council has established.  If a community or organization does not have clear direction, the city administrator should first consider finding the best way to accomplish setting a clear direction.  This is something that the Mayor of Oakdale and I made a priority, especially when new councilmembers and staff were introduced into the organization.

Once in place, it is the role of the administrator and manager to implement the plan.  At the beginning of each year, one should consider how the plan for the previous year has gone, how and what the organization will need to implement the current year’s plan and start looking toward the creation and implementation of next year’s plan.

The beginning of each new year is an opportunity to reflect upon the past, evaluate the present, and prepare for the future.

New Councilmembers

The beginning of a new year often brings changes to the council and board.  New members can feel excitement for their new role as well an overwhelming feeling of uncertainty.  It is imperative that administrators and managers help guide and assist newly elected officials toward success in their new role.  Remembering that this could mean different things to each person and building a relationship with individuals is the key to deciphering how best to connect and communicate with them.

Provide the opportunity for success by connecting with each individual and guiding them toward team, organizational, and personal achievement.

Budget Process

As with strategic planning, the beginning of the year is the time to start laying the groundwork for the next budget.  Budgeting is truly a year-round process.  Once the annual budget is adopted in December, there is a short break and the process begins again early in the year.  Utilizing the strategic and comprehensive plans in planning and crafting the budget process for the year is imperative.  These documents provide the priorities of the council and board, and identify investments being considered.  During my time in Oakdale, the finance director and I would meet with each department head to strategize how best to incorporate the short-term needs of each department with the long-term goals of the council.

Ensure successful budget preparation by planning and crafting a framework for the process and incorporating strategic & comprehensive plans and goals.

Legislative Session & Priorities

With each new year comes a new Legislative Session and the opportunity for municipalities to advocate on behalf of priorities and projects of importance.  Having a relationship and building a connection with the Senators and House Members that represent your area is vital.  Being able to work with them toward the passage of those priorities and projects is essential.  They want to work on behalf of their constituents, so help them by having a list of priorities ready that they will advocate for.  Another valuable resource in this area is the League of Minnesota Cities (LMC).  Work with the LMC on your list and how to advocate with your Legislators.  Throughout my career, I have been part of the LMC’s policy committee process.  Consider taking advantage of this opportunity to have a voice in the legislative process for city issues.

Having a relationship and connection with your state elected officials, the LMC, and a list of priorities ready for them to advocate on your behalf is an important piece of the annual thought process for an administrator and manager.

Relationships & Connections

At the beginning of each year, take stock of and lean into those connections and relationships that will be vital to the success of the organization and you as a professional.  These might include connecting with county or surrounding municipal partners, key business or non-profit community contacts, state or federal elected officials, professional organizations such as the LMC, Association of Minnesota Counties, or the Minnesota City/County Managers Association.  And do not forget your family, friends, and neighbors who are invaluable in keeping you grounded and connected.  There have been many times when I have taken the opportunity to “bounce” thoughts and ideas off friends and neighbors to gather feedback even if they will not be the ones directly affected.

The value of connections and relationships at the professional and personal levels cannot be overstated.  Be strategic about fostering these relationships now for a successful year.

Conclusion

Creating plans, budgets, legislative priorities, integrating new councilmembers, and leaning into relationships & connections is an ongoing process; however, taking the opportunity to focus on them at the beginning of each year is an important aspect of municipal leadership and management.

Optimize your data

By Justin Hansen, Director of GIS Services, WSB

As the world continues to evolve through the advancement of technology, new opportunities and challenges arise that you may, or may not, know the best way to tackle. Staying abreast of new systems and solutions can be a daunting, even overwhelming, task.

At WSB, we use Geographic Information Systems (GIS) to improve the way organizations acquire, understand and use their data. A successful GIS program employs geospatial technology to improve the quality of services, positively impact the decision-making of a community, become a central location for all data and improve overall workflow. To help simplify it for you, we will share some of the most common issues that we encounter and provide some advice on how to handle them.

Unable to retrieve data quickly enough

A properly designed and managed GIS will allow you access to all your organizations information at the touch of a button. Through field to office integration software, your team can enter field data directly from the site of the work and make the data immediately available to you. If you need to be able to verify a critical utility repair in order to calm concerned residents, your team can document the nature of the problem, how and when it was repaired, and include supporting photos or documents.

Unable to locate needed documents

It is time to go paperless. There is no need to continue to store paper documents in your office. They take up unnecessary space, get disorganized and go missing. Have you ever needed to find an as-built in order to verify the location of utility lines and been unable to find the final version? Using a GIS will allow you to convert all your supporting documents into digital files, tag them to any relevant accounts or locations for easy retrieval, and support a greener way of conducting business.

My data is outdated

Using ledgers and spreadsheets to manage your data quickly becomes tedious, time consuming and inefficient. If your system for tracking data involves any of these methods, it is likely current data has not been entered more than once. Imagine you need to share results of a lift station’s most recent inspection, but the most current document you can find is 3 years old. This could create a serious problem if you are unable to provide accurate findings. To ensure your group is working with the most accurate data available, a GIS is an easy and organized way to allow anyone the ability to enter information, keep it all stored in one central location, and control access to sensitive data.

My team is not able to work together efficiently

Do you have people working from more than one location? Do you often find you are emailing the same spreadsheet to multiple people to add data? There must be a more efficient way for your team to work together, right? A GIS can allow everyone on your team the ability to access, edit, and report from your groups database without wondering which version is the most up to date. It can save you time and frustration, allowing your group to spend their valuable time on other projects.

Our GIS group has worked with many clients to find solutions to their data problems. If you find yourself wondering if there might be a better way, please contact us. We will help to determine which of our complimentary, introductory services can improve how your organization works.

Make the most of your pavement

By Sheue Torng Lee, Graduate Engineer, WSB

As a city leader you are responsible for many things; managing budgets, people, community needs, city assets, and the list goes on. What if there were a system in place for managing one of your largest assets, the city streets?

A pavement management program provides a systematic method of inspecting and rating the pavement condition of your roads; including the analysis of various maintenance and rehabilitation strategies. As part of the program, we use pavement forensics to identify the pavement structure and condition underneath the visible surface of the pavement. We look at the depths and condition of the pavement layers, signs of bonding or de-bonding, and distresses that may not be visible from the surface. Data collected from the pavement cores during forensics, provides a better understanding of the roadway sections and allows us to determine cost-effective and appropriate pavement rehabilitation techniques. The program is designed to help you get the most out of your available resources.

The collected data is used to evaluate funding needs and, in some cases, implement new funding tools such as franchise fees. We conduct analysis on various budget scenarios to help you forecast the funding required to maintain your network of roadways. The inspection results are useful for talking with residents and City Council Members regarding necessary road improvements and are vital in justifying the funding needed to maintain city streets as part of your Capital Improvement Plans. 

A thorough pavement management plan can save you from expensive, and sometimes unnecessary, repairs. The data can help you to narrow down the areas that require preventive maintenance and rehabilitation. An effective program will emphasize maintaining streets that are in good condition to extend their service life, as preventive maintenance is less costly than rehabilitation.  

However, when streets have deteriorated and demand more extensive repair, your pavement management program allows you to plan for those projects and minimize the risks of having to make extensive changes to the project. By successfully implementing a pavement management program, you can improve the overall performance and life of your roads, saving the city and taxpayers time and money.

Solar Development and Wetland Regulation

Roxy Robertson, Environmental Scientist, WSB

Solar production in Minnesota has seen dramatic increases in the past few years and continues to grow across the state. With this rapid growth comes challenges about how to regulate the installation of panels at a local level. According to the Solar Energy Industries Association (SEIA), Minnesota has already invested $1.9 billion on solar and additional growth is projected at 834 megawatts over the next five years. The installations of solar “farms”, vast arrays of solar panels, can be seen throughout the state and can generate up to a megawatt of electricity each. Development of these sites often requires large, vacant parcels which may also support natural habitats such as wetlands.

The development application process for these solar farms can be challenging for municipalities, especially those who act as the local government unit (LGU) for the Wetland Conservation Act (WCA). Developers must work collaboratively with LGUs to demonstrate a sequencing process that shows how their projects are avoiding, minimizing, and if necessary, replacing unavoidable wetland impacts. Under the WCA rule, the installation of posts and pilings from solar panels has traditionally not been considered a wetland impact if they do not significantly alter the wetland function and value. But, as the solar industry grows, LGUs have had questions about whether the installation of solar panels may lead to loss in wetland quality over time which would be a violation of WCA. A strong measure of wetland quality comes from the diversity of the plants within the wetland, factors like shading from panels and disturbances from construction may lead to conversion of the wetland vegetative community, and subsequently, the wetland quality. Loss of wetlands and wetland quality has overlapping effects on drinking water, lake and stream health, native wildlife, soil heath, and pollinators, all of which are important to our Minnesota ecosystems.

So why does this affect you? Many municipalities act as the LGU responsible for implementing WCA. LGUs, alongside other regulating agencies, have been struggling to make impact determinations for sites that install panels in wetlands because there is little data available that addresses the future outcomes of these natural areas. There is a growing need for baseline data about how the quality of wetland vegetation changes throughout the solar development process. If data were available, LGUs could use these as a basis for making determinations.  

Having baseline data about wetland vegetative quality under solar panels is beneficial to both regulators and developers. Regulators will have a scientific basis for making wetland impact determinations within their jurisdiction and developers will see more consistency across municipalities during the permitting process. We may see that wetland quality improves under solar panels in certain circumstances through the planting of native vegetation upon completion of development. In other scenarios, wetland quality may decrease if the existing wetland was of higher quality prior to development.

WSB has started an exciting initiative to collect this baseline data at various solar sites in Minnesota. In 2019, environmental scientists at WSB surveyed wetland vegetation under existing or planned solar panels at four solar farms in varying stages of development. Additional data collection at these sites is planned for the summer of 2020. WSB is in the process of developing a Legislative-Citizen Commission on Minnesota Resources (LCCMR) grant application to expand this research in 2021 to more sites across the state and to include other metrics that may influence vegetation such as fixed-tilt or tracker panel types. Support of this research from municipalities will be important for the LCCMR application process and we encourage you to join us in the process through letters of support, in-kind hours, monetary support, or providing access to solar farms within your area. It is an exciting time in the renewable energy industry and WSB is committed to helping advance the clean energy market in a way that is sustainable to our Minnesota environment that we all cherish.

Road Reconstruction Happens Year-Round

Brandon Movall, Graduate Engineer, WSB

Road reconstruction projects affect residents of all cities, from large metropolitan areas to small rural centers. While residents are very familiar with the sight of bright orange cones and excavating machines that are shown for a few months in the summer, few know the full amount of work that goes into improving roads and public utilities the rest of the year. Here is a season by season breakdown of how a road reconstruction project comes to life:

Summer/Fall

The summer/fall season is when work on a specific project typically begins for the upcoming construction season, with the start of preliminary design. Depending on the size and complexity of the project, preliminary design can begin months or even years earlier than this time frame.

The preliminary design begins by collecting extensive information on the existing conditions of the public infrastructure in the project area. This can be done through a topographic survey of the area, taking geotechnical readings on the materials in the area, and even reviewing asset management systems or old plan sets for the project area.

Based on the information gathered, the project team (typically consisting of transportation and municipal engineers) can identify improvements needed within the project area. The team then provides a preliminary overview of proposed improvements to the project owners, private utility companies such as gas or electric that could be impacted, residents, business owners and other stakeholders in the project area. At this point, public engagement becomes critical to connect with the owners, companies, and residents to solicit feedback on the proposed improvements and gather additional information on existing conditions. This feedback can be achieved through neighborhood meetings, showcasing visualizations, and conducting community surveys.

After gathering feedback, the project team presents the proposed infrastructure improvements along with estimates on costs and schedule to the project owners, and, if the project is still supported, begins final design.

Fall/Winter

The fall/winter season is dedicated to final design of the project. The team (supported by site & landscape designers, water resource engineers and wastewater engineers) completes final design documents that specialists in infrastructure construction techniques will use build the project. These documents will complete the city’s vision for the project while ensuring it is properly engineered and safe for residents. The design includes not only the pavement that residents drive on, but also all of the public utilities in the project area, such as storm sewer, sanitary sewer and watermain.

During this time, the project will also be reviewed by permitting agencies that have jurisdiction over certain aspects of the project. These agencies, such as a county or state transportation agency, may have jurisdiction over neighboring roads. Other agencies, like a state departments of natural resources, may review the project for environmental regulations within the project area.

Once the plans and specifications are complete, the project team will share the finished design documents with the project owner. The project is then authorized to be bid for construction.

Winter/Spring

The spring season is used to bid the project and prepare for construction. After the project is authorized to be bid, a notice goes out to contractors notifying them of the project and providing them access to the plans and specifications. If a contractor is interested in constructing the project, they submit a set of documents to the project owner. These documents include insurance information, proof of bonds, and their bid of how much they believe it will cost to construct the project. At an arranged time, a contractor will be selected from those that submitted a bid.

Once a contractor has been selected, project management and construction administration begins. Preliminary construction meetings are held with the project owners, the project team, and other stakeholders, to prepare for the upcoming construction of the project.

Spring/Summer

After the preliminary and final designs are complete, construction -the most visible stage of a project – can begin during the spring/summer season. During this time, the project team monitors contractor progress on the project, and ensures that the construction is being done according to the plans and specifications that were prepared in the fall/winter. This monitoring consists of a variety of activities that include construction material testing, environmental compliance, and more.

Because the winter season is often the longest in the Midwest, the time frame for construction is extremely short. To protect the final product, some projects require contractors to wait until after winter to finish minor paving and restoration work during the following spring/summer season.

Once all of the work is complete and accepted by the project owner, the contract is finalized and closed out. Usually a maintenance period is required of the contractor, during which time they are responsible to address any workmanship or materials defects which are identified following close out.

At this point, the project is considered complete. The project owner is responsible for ongoing maintenance and repair of the infrastructure through their Public Works Department. The new seasonal cycle begins with the next project that was prioritized or identified within that community’s Capital Improvement Plan or similar planning document.

Top 5 Signs Your Lift Station Needs Rehabilitation

As infrastructure ages, you will need to prioritize which items to fix first. You need to determine which items to do this year and which items can wait for future plans. How do you know when it is time to put a lift station at the top of the list? Below are 5 signs that your lift station is nearing the end of their usable life cycle.

1. Clogged Pumps – Have your maintenance crews been spending an inordinate amount of time and resources addressing clogged pumps? Rags, sanitary products, and many other items find their way into your city’s sanitary sewer, but cannot be passed by the old style impellers. It might be time to upgrade your pumps to modern non-clog impellers to address this maintenance nightmare.

2. Increased Pump Runtimes – Over time, pumps lose their efficiency causing them to generate less flow at lower velocities. This can cause solids to settle in the forcemain and exacerbate the pump inefficiencies. Compare your electricity bills over time. If the number of kilowatt hours used has gone up, it might be time to dig into the issue.

3. Electrical & Communication Failures – Old starters, leaking mechanical seals, electrical service changes: these items can cause tripped circuit breakers and blown fuses. If your SCADA system isn’t communicating these failures to maintenance staff, you might find out from an angry resident with sewage backup in their basement. Electrical and communication upgrades will help your staff maintain real-time status updates and put your mind at ease.

4. Degraded Concrete, Piping & Equipment – Sanitary sewage can generate corrosive hydrogen sulfide (H2S) gas that chews up the lift station concrete, pump rails, piping, hatches, and valves. Ensuring proper pump cycles and providing mixing to break up gas producing materials in the lift station can help reduce gas generation, but it may also be necessary to coat the concrete with a corrosion resistant barrier and replace lift station equipment with more robust materials. Have the field crew take photos for you to review.

5. Safety – Are your lift station hatches equipped with fall protection? Are your workers using tripods with harnesses for lift station access, or are they relying on deteriorated manhole steps? Review the safety features of your lift stations and make sure your crew has the right equipment to do their job safely. Lift stations are a very hazardous environment, but simple safety features and protocols can make all the difference.
