The Modeling that Started it All
Watershed Planning
Through a series of impactful projects, we have supported the City in working to achieve its goals to be a safe, accessible, and environmentally conscious community. We leveraged our extensive experience in hydraulic and hydrologic (H&H) modeling to help the City manage their urban stormwater systems effectively. Examples of this H&H work include:
• XPSWMM Models for Northeast and Southeast Minneapolis: We used XPSWMM to create H&H models for these areas, simulating multiple storm events to identify flood-prone areas, at-risk structures, and infrastructure deficiencies. By focusing on six watersheds, we provided a comprehensive analysis that addressed the unique challenges and opportunities within each area.
• 1NE XPSWMM Modeling Projects for Northeast Minneapolis: Commissioned by the Mississippi Watershed Management Organization (MWMO), this project involved creating an H&H model for a 2,100-acre storm drainage system that outlets to the Mississippi River. The model helps identify flood-prone issues and manage storm events as large as the 100-year event.
• P8 Models for Northeast Minneapolis: We developed P8 models for the 1NE watershed and the southern end of the Northeast Minneapolis Watershed. These models quantify average annual total suspended solids and total phosphorus yields, aiding in informed decision-making for future stormwater treatment practices.

Through these projects, the City and watershed gained valuable insights into the complexities of the urban infrastructure and environmental management within the watershed studied.
Innovative Tech Solutions for Urban Challenges
Smoke Detection
Minneapolis has elevated its sewer system testing with a novel approach using drone technology. The City annually tests its sewers to identify any problematic connections between sanitary and stormwater systems. City staff then work with homeowners to remove any identified sanitary and stormwater system connections, effectively blocking excess pollutants from entering the stormwater systems that may lead to downstream waterbodies. Beginning in 2018, HEI used drones to photograph areas typically difficult to access, eliminating the need for manual, risky rooftop inspections. City staff piped smoke through the storm sewers, and our team flew the drone over testing corridors while City staff managed the camera to detect smoke and document findings. Detected smoke was photographed, geo-tagged, and wirelessly transmitted to an application to record for future repairs.
This project showcases the City’s commitment to leveraging technology for efficient urban infrastructure management. It also supports its goal to improve and protect its water quality.
Gopher State One Call Scripting
In 2020, the City hired HEI to develop a GIS tool for accessing Gopher State One Call (GSOC) so they could perform safe and informed excavations. HEI reviewed and aligned Python scripts with Korterra software, enhancing automation tools for GSOC’s operations. The team also refined Python modules for easier future modifications, targeting key areas such as Korterra integration, email communications, backend data mining, and ArcGIS Online consultation.
Throughout the project, HEI established a test environment to validate the application against the City’s requirements, conducting thorough tests and debugging.
This innovation represents a significant step in safeguarding both utilities and individuals during excavation projects in Minneapolis.
CCTV Sewer Inspection Software Integration

Chad Nunemacher cnunemacher@houstoneng.com
Thanks to a collaboration with HEI, the City was able to integrate its closed-circuit television (CCTV) sewer inspection software, GraniteXP, with its GIS database to efficiently manage their urban infrastructure. This integration resolves data discrepancies and streamlines the workflow between GraniteXP and the City’s GIS database.
HEI’s development of a Python script to convert observation data into geodatabase feature classes is a game-changer for the City. It provides staff with a visual tool to evaluate pipe conditions and prioritize maintenance, enhancing the efficiency and accuracy of the City’s sewer management system.
This project exemplifies the innovative use of technology in city planning and maintenance, setting a precedent for future urban infrastructure projects.
Projects Shifting from the Desktop to the Road
HEI continues to research and implement cutting-edge practices, ensuring that our transportation projects serve our communities while incorporating environmental sustainability. This enables our team to design more resilient and efficient systems that address both current and future challenges to enhance urban infrastructure and community well-being in Minneapolis and other communities.
Southwest Windom Neighborhood
Our team is proud to support the City in its commitment to safe, environmentally sound, and pedestrian-friendly transportation projects. The Southwest Windom Neighborhood Street Reconstruction project began in 2019 and marked a significant milestone for HEI, showcasing our dedication to enhancing urban infrastructure and fostering a vibrant community.
This project included narrowing the roadways, adding curb extensions to promote lower travel speeds, and enhancing pedestrian safety. Realigned intersections clearly define roadway limits and vehicular right-of-way, reducing the risk of accidents. New sidewalks with ADA-compliance measures ensure that
all residents can navigate the neighborhood safely and comfortably. By fully removing the existing street; making subgrade corrections; and installing new pavement, curb, gutter, and sidewalks; we provided a more durable and reliable transportation network. Public and private utility improvements, along with new storm sewer mains, enhanced the neighborhood’s infrastructure. By reducing impervious surface and adding green stormwater infrastructure (GSI), such as bioretention basins, we reduced the stormwater runoff from the neighborhood. This helped to reduce downstream flooding, improve water quality, and reduce the environmental impact.
The construction was completed in 2020 and marked a pivotal achievement in the City’s ongoing efforts to improve the overall quality of life for its residents.
Johnson Street Northeast
Johnson Street Northeast is a bustling corridor with many modes of traffic, including pedestrians, cyclists, vehicles, and more. To better serve motorists and pedestrians as well as reduce the potential for crashes, the City kicked off a project to reconstruct four blocks of Johnson Street Northeast from 18th Avenue Northeast to Lowry Avenue Northeast.
Our design accomplished these goals by revising the old, four-lane corridor with sidewalks on both sides to a new, two-lane corridor with dedicated parking areas, bikeways on the west side of the street, sidewalks, and green boulevards. This reduced the amount of
impervious surface along the corridor, helping to improve water quality and stormwater management. We also prioritized bike access and pedestrian safety through creating a new bikeway, adding new curb extensions, putting a raised median at the intersections, and adding a new pedestrian crossing. This significantly calmed traffic; provided new opportunities for safe, multi-modal access to the roadway; and reduced the potential for accidents, making the streets more welcoming for everyone. Construction was completed in 2022. Through this project, HEI has not only improved the immediate functionality of the Johnson Street Northeast corridor, which is used by more than 20,000 vehicles a day, but also laid the groundwork for a more sustainable and community-focused future.
HEI is proud to have contributed to this transformative project and looks forward to continuing our partnership with the City to enhance urban infrastructure and community well-being.

Our projects with the City underscore its position at the forefront of stormwater engineering practices, reflecting its dedication to creating a sustainable, safe, and beautiful environment. The following projects are in progress and support the City’s goals.
Shingle Creek Parkway - Anticipated to be Constructed in 2025
The City will replace aging storm sewer pipes and manholes at four intersections along Shingle Creek Parkway that outlet to Shingle Creek and have caused streambank erosion. By replacing the storm sewer conveyance system and adding multiple GSIs, the City will prevent sediment from entering Shingle Creek, protecting its water quality. HEI will assess the stability of each storm sewer outfall and design its replacement.
This project addresses deficient storm sewer infrastructure at 47th Avenue North, Fremont Avenue North, 46th Avenue North, and Dupont Avenue North. HEI collaborated with the City to collect site data and conduct surveys at these intersections. The team coordinated with the Shingle Creek Watershed Management Organization to ensure compliance with any necessary permits and to receive grant money to provide GSI above and beyond the treatment requirements of the City and watershed. Green Infrastructure and Accessibility
In addition to storm sewer replacement, HEI designed GSIs for the corridor: two rain gardens and a regenerative stormwater conveyance system (step pool) to treat and convey stormwater into Shingle Creek. The step pool design provides a series of treatment pools to reduce sedimentation, stabilize the creek bank, and provide oxygen to the stormwater runoff. The project will replace the pavement, sidewalks, and curb and gutter as well as evaluate pedestrian ramps to meet current ADA standards.
Newton Avenue Sanitary Sewers - Anticipated to be Constructed in 2025
By upgrading the aging sanitary sewer infrastructure along Newton Avenue and 52nd Avenue North, the City aims to improve the reliability and reduce maintenance of the sewer system, significantly reducing the risk of leaks and failures. In 2023, the City further demonstrated its commitment to community improvement by expanding HEI’s services to include helical pile design, ensuring robust and sustainable infrastructure for the future. Helical piles provide a stable foundation for the sanitary sewer without removing unstable soil, which reduces construction cost and installation time.
The project will replace 553 feet of sanitary sewer main and three manholes. This project is designed to ensure minimal disruption to the surrounding pavement, storm sewer, and water services, thereby maintaining the integrity of the area. Additionally, HEI will reconnect sanitary sewer services and replace impacted water services, further improving the community’s infrastructure.
HEI’s team is working closely with the City, Metropolitan Council, residents, and utility providers to gather site data, conduct surveys, and ensure smooth project execution. Regular meetings and progress updates will provide transparency and effective communication throughout the project. The design and planning were completed in October 2024.
1st Avenue Development - Anticipated to be Constructed in 2026
The 1st Avenue North Development project is set to enhance pedestrian safety, bike connectivity, and overall accessibility. HEI’s team will leverage our extensive expertise in stormwater management GSI to ensure that the project not only meets water quality and rate control requirements but also adds aesthetic value to the community. The City is committed to providing safe, accessible, and inclusive transportation services, and we’re proud to support these efforts. We’ll be installing new sidewalks, bikeways, curb extensions, and ADA-compliant crossings to make 1st Avenue North safer and more accessible for everyone. Upgraded utilities, including water main and sanitary sewer repairs, will ensure reliable services for residents and businesses. Our GSI designs will manage stormwater effectively, contributing to a healthier environment.
Digging Deep How Dredging Shapes Our Waterways and Future Featured Service Area: Dredging
What is Dredging?
One of the main drivers behind poor water quality is sedimentation in lakes, ponds, ditches, and more. HEI often prescribes dredging to remove the excess sediment and nutrients as one part of a successful restoration project. Dredging provides several benefits, including increased water depth, enhancement of aquatic habitat, and removal of nutrients that can be released into the water column and drive algal growth.
There are two types of dredging, both of which HEI has applied in a variety of projects: mechanical dredging, which uses heavy machinery like excavators to scoop up materials; and hydraulic dredging, which uses large pumps to move a slurry of water and dredge materials through a pipeline.
The key benefits for dredging include increased flood storage, land reclamation, environmental cleanup, infrastructure development, ecological benefits, and recreation opportunities. Dredging can help control flooding by deepening rivers or restoring flood storage capacity in reservoirs. Dredged materials are typically stored in designated spoil sites designed to stabilize and contain sediment. In some cases, it may be possible to use dredged sediments to reclaim or create useful land area adjacent to shore.
Lake Redwood Reclamation, Redwood Falls, Minnesota Lake Redwood was created in the early 1900s to provide recreational opportunities to the community of Redwood Falls. The lake’s recreational benefits made
it a staple for the City and surrounding communities. The City also added a hydroelectric plant to supplement its electrical power supply. By the 1980s, the 65-acre lake was full of accumulated sediment and could no longer support recreational activities.
HEI was engaged by the Redwood Cottonwood Rivers Control Area (RCRCA) to develop a plan to hydraulically dredge the lake and increase the average depth from 2.3 feet to 10 feet, with a maximum depth of 20 feet. HEI also supported the RCRCA with the complicated process to secure permit authorizations from the Minnesota Department of Natural Resources, the US Army Corps of Engineers, Redwood County, the Minnesota Department of Transportation, and others to complete the project.
The project consisted of two phases. During Phase I, HEI designed and supported construction of a confined disposal facility, where the dredged materials were transported via pipeline. After the sediment settled, clean water was returned through a ditch to the Minnesota River. Phase II consisted of the removal of 682,000 cubic yards of accumulated sediment materials via a 3.3-mile pipeline route to the disposal facility.
Dredging Lake Redwood improved the lake’s water quality, which resulted in a higher quality fishery as well as aquatic plant communities. The deeper and cleaner lake also helped increase the hydroelectric plant’s productivity.
Project Example:
Before and after dredging and structure repair on Oasis Pond in Roseville, Minnesota. Mechanical dredging was completed on this pond to restore water quality and transport sediment downstream.
Walnut Creek Sediment Basin Restoration, Papillion, Nebraska
Years of development have filled the Walnut Creek sediment basin with sediment and nutrients, allowing them to flow into Walnut Creek Lake. Restoring the basin will enable it to trap these materials again, improving water quality downstream. The restoration of the Walnut Creek sediment basin to its initial purpose would again allow for sediment and nutrients to settle out in the basin prior to reaching Walnut Creek Lake.
HEI evaluated current conditions of the basin and developed a design to remove accumulated sediments and provide storage capacity for estimated future sediment loads while still maintaining adequate depths. As part of the project, HEI designed a containment site to place the sediment removed from the basin within the park in a manner that did not disrupt existing uses. The restoration project also included a walkout peninsula, which is incorporated as a water access feature for the adjacent dog park.
Construction was successfully completed in the spring of 2024, and the basin is now providing protection to Walnut Creek Lake as originally intended.
Lake of the Hills Restoration, Scott County, Iowa
HEI was hired by the Scott County Conservation Board to complete planning, design, engineering, and permitting services for a variety of projects associated with the restoration of several lakes within West Lake Park (Lake of the Hills, Bluegrass Lake, Railroad Lake, and Lambach Lake). Overarching goals of this project included sediment and

nutrient load reductions for water quality improvement, increased lake depth and fish habitat diversity, and improved shorelines to reduce erosion and increase angler access at the West Lake Complex. Bluegrass Lake, Railroad Lake, and Lamback Lake were designed to be retention ponds and protect Lake of the Hills. Over time, sediment was transported through overland runoff and accumulated in the 50-year-old, man-made lakes. A major component for this project was the prioritization and design of potential watershed best management practices and in-lake improvements. HEI evaluated multiple dredging locations and techniques, considered sediment handling of each option, and developed a sediment storage site to safely store the dredged materials. A cost-benefit analysis was used to determine which locations and dredging options should be implemented in the final design. In-lake dredging was completed to remove legacy sediment, improve water quality and fish habitat, and stabilize the shoreline.
What’s Next
Dredging is critical for both flood prevention and protection as well as managing river depths to reduce flood risks.
In addition to flood prevention, dredging plays a vital role in environmental restoration and water quality management. It helps to remove polluted sediments from waterways, restore habitats, and promote biodiversity, ensuring that critical infrastructure and ecosystems remain resilient for the future.

Enhancing Water and Wastewater Systems: The Collaborative
The Turtle Mountain Band of Chippewa Indians (TMBCI) water system is a success story of continual improvements and developments for more than 30 years. The Turtle Mountain Public Utilities Commission (PUC) began working with HEI around 25 years ago to meet water supply needs through the creation of a 30-year Water System Master Plan to stay ahead of residents’ needs.
The main requirement established by the TMBCI was that the master plan be a forward-looking, living document to guide water system improvements for both long-term and critical, short-term needs. The master plan needed to be structured to meet the United States Bureau of Reclamation (BOR) requirements for a final engineering report, while expanding the scope to address critical needs identified by the TMBCI to properly allocate limited funds to maximize project benefits. Upon master plan completion, the TMBCI system was determined to have more than $80 million in water system improvement needs.
Read more about the PUC and development of the master plan on page 6 of our previous newsletter article on the topic! https://bit.ly/4eIZUHj
Through a cooperative approach and the utilization of both state and federal funding, TMBCI and HEI have successfully addressed system deficiencies and laid the groundwork for future improvements, building a robust and reliable water system for the community.
Success of TMBCI and HEI
Background and History
After the development of the master plan and revolving five-year plans, early milestones of success included the creation of multiple distributed water stations strategically located to ensure that even the most remote areas of the reservation had access to clean and reliable water. These initial efforts in improving access to water for both tribal and non-tribal residents paved the way for more ambitious projects, such as the expansion of the Highway 43 water main and the enhancement of the TMBCI Water Treatment Plant (WTP).
The master plan was utilized to fill the Indian Health Service (IHS) Sanitation Deficiency System (SDS) database by addressing deficiencies associated with water, sewer, and solid waste projects on reservations. Initially, IHS funded and completed many water system improvement projects. However, as time went on and deficiencies were not addressed in an acceptable timeframe due to funding constraints, IHS began providing funding to projects designed
and constructed by HEI, such as phases of the Highway 43 Corridor.
Current Efforts and Projects
TMBCI is actively working on enhancing their water system to ensure reliable and efficient service. Key projects include the expansion of the Highway 43 water main, which was separated into five phases designed by HEI. Phase 3 was recently completed and Phase 4 will be seeing completion soon. Phase 5 has been awarded and construction will begin soon.
Another significant project is the expansion of the WTP, which involves upgrading existing facilities to increase capacity and improve water quality.
The Thorne Reservoir project will enhance water storage and will simplify the water supply to the WTP by equalizing wellhead pressure and unifying the raw water quality by blending the water sources. Other projects under design include two phases of raw water main replacement projects, an additional booster station and water main expansion, replacement of the over-pressurized water supply main to the Belcourt community, and five projects to replace failing glued PVC water mains across the Reservation. These efforts are supported by state and federal funding, exemplifying the collaborative nature of the project.
An ongoing effort intertwined with other projects is the GIS mapping system that HEI is continuously working on in tandem with PUC. This multi-purpose project helps the PUC in many ways: responding to regulatory agencies, project planning,

asset management, records drawing, communications with operators in the field, hydraulic modeling, inter-departmental communications, community engagement, and serving as an asset for quickly assembling maps and informational pieces for interested parties.
HEI’s Involvement and Collaboration
The collaborative nature of these projects cannot be overstated. TMBCI worked closely with various state and federal agencies to secure the necessary funding and support for their initiatives.
HEI’s expertise and role in creating the reservation-wide master plan and working with the IHS to ensure its implementation was a key factor in the overall success of the water system improvements.
Throughout the projects related to the Water System Master Plan, collaboration between engaged parties has been continuous, including TMBCI, HEI, US Department of Agriculture Rural Development (USDA-RD), BOR, North Dakota Department of Water Resources, and IHS. HEI has been able to continuously supply data from our GIS modeling work. This data has been utilized by the federal agencies to identify deficiencies and then obtain funding to correct the deficiencies, with all engineering and project management completed by HEI or IHS. An example of this collaboration is the Three Mile Road water main replacement. The area was identified through the model as having low pressure (less than 20 psi, whereas 40-70 is normal for a residential home). The TMBCI received Cares Act funding to address the issue, but the funding
needed to be spent within a limited timeframe. IHS had completed surveying in the area but did not have the staffing needed to complete the design within the timeframe. However, IHS was able to provide the survey information to HEI, who was then able to complete a design package, assist TMBCI with the bidding process, and manage the construction of the water main replacement project. This collaborative approach allowed the project to be completed within the required timeframe and address the pressure issue for customers.
Future Plans and Vision
Looking ahead—as they have done since the initial development of their Water System Master Plan (WSMP)—TMBCI has ambitious plans to further enhance their water and wastewater systems. A key initiative includes the development of a Regional Sewer Master Plan to address the growing needs of the community by expanding and upgrading the existing sewer infrastructure. This ambitious project will address the deficiencies associated with the existing community wastewater systems, while at the same time addressing the significant problem of individual septic systems that have failed. The deficiencies identified and projects developed to address them will likely be similar in scale to the WSMP if not larger. Upon completion of the new plan, projects will be identified, and the TMBCI will be able to seek funding from whichever source aligns well with the individual project, whether it be IHS, USDA-RD, the EPA, or the State of North Dakota.
TMBCI is also focused on improving the operational efficiency of its water and wastewater systems through advanced technologies and processes. The future phases of the WTP expansion project will incorporate state-of-the-art treatment processes such as Ceramic Ultrafiltration to enhance water quality and increase capacity. Continued collaboration and funding from agencies and stakeholders will be essential for future advancements.
water mains. Additional projects being designed include the Highway 5 Water Main Replacement, well field expansion and renovations, renovation of Booster Station A, and the installation of individual meters.
Community Impact and Benefits
The collaborative efforts of TMBCI and HEI in enhancing the water and wastewater system have had a profound impact on the community, improving the quality of life for both tribal and non-tribal residents. Access to clean and reliable water is essential for health and well-being, and the upgraded water system ensures that all residents have access to this vital resource. The improved systems also benefit the broader regional community, supporting surrounding areas including recreational sites and other communities.
Masterfully Planned
With thorough and detailed planning, consistent funding, and a cooperative and iterative approach, TMBCI has successfully addressed system deficiencies and laid the groundwork for future improvements with HEI supporting them every step of the way. The ongoing and future projects will continue to improve the quality of life for both tribal and non-tribal residents, fostering a sense of community and cooperation among stakeholders. The commitment to enhancing water infrastructure demonstrates TMBCI’s dedication to providing essential resources and supporting the well-being of the community.

PROJECT SNAPSHOTS
We’d love to showcase all that we do at HEI, but we’d run out of pages! Here’s a quick overview of some projects we’ve been working on or recently completed.
The floodplain map shows the blue Zone A (100-year) and the orange Zone X (500-year) as part of the new floodplain ordinance.
2D Base Level Engineering Floodplain Modeling
Sioux
Falls, South Dakota
HEI has been providing technical assistance to the City of Sioux Falls as it manages its floodplain ordinance. This includes ensuring a proposed development in the floodplain results in “no rise” to the base flood elevation, and that compensatory floodplain storage is provided resulting in a net balance of cut and fill. Our team is currently managing the floodplain models and mapping as development applications are submitted to the City. Through this, HEI has been independently contracting with developers to conduct the necessary hydraulic analyses using the interim 2D Base Level Engineering models to ensure the proposed developments meet the floodplain requirements. HEI’s role has been instrumental for the City in achieving its floodplain management goal of minimizing flood risk for its residents.
Interstate 94 Reconstruction
West Fargo, North Dakota
To maintain safe, efficient movement of people and goods along one of the busiest corridors in Fargo-MoorheadWest Fargo, the North Dakota Department of Transportation (NDDOT) enlisted HEI to prepare the design for both eastbound and westbound I-94 from the Raymond Interchange to west of the Sheyenne Street Interchange. The Raymond Interchange received a 1-inch mill and 2-inch hot mix asphalt overlay of the ramps and crossroad, but the Sheyenne Street Interchange ramps were reconstructed due to deteriorated pavemented conditions.
The project also incorporated High-Tension Median Guardrail to minimize vehicles crossing the median and avoiding serious crashes. Additionally, the team leveraged HEI’s extensive experience with both the NDDOT and the Metro Flood Diversion Authority by bridging communication and providing coordination between the I-94 and F-M Area Diversion projects. As the F-M Area Diversion project crosses I-94 immediately west of this project, coordination between agencies was required for traffic control measures. This included the siting of the west median crossover, which was an important factor to avoid driver confusion and maintain a safe roadway.

Sand Draw Creek Conservation and Stabilization Project—Phase IV
Brown County, Nebraska
In 2019, the Middle Niobrara Natural Resources District began the Long Pine Creek Watershed Plan and Environmental Assessment to determine stream restoration and habitat improvement needs throughout the watershed.
This effort identified and prioritized 11 stream reaches (Tier 1 locations) within the watershed for restoration efforts and included preliminary design, definition of environmental impacts, and ecosystem analyses of these high priority locations. Sand Draw Creek was identified through this effort and HEI was tasked with the restoration, which included stream assessments, wetland delineation, preliminary and final design, permitting, construction oversight, and funding coordination. With 16 feet of headcut (a sudden step in a stream channel) migrating toward this location, significant mitigation measures were required with careful consideration for endangered species and fish passage. This project utilized funding from multiple state and federal agencies and provided crucial improvements to stream health and water quality.
North Dakota State Mill Tracks 1-3 Rehabilitation
Grand Forks, North Dakota
HEI is proud to have completed a recent project for the North Dakota State Mill and Elevator (the Mill), which focused on rail infrastructure and drainage improvements. The project involved removing existing railroad tracks and replacing them with new tracks and concrete crossing surfaces. Additionally, aging asphalt paving was replaced with concrete paving, and drainage improvements were made to ensure long-term stability. These upgrades not only enhance the visual aesthetics outside the Mill’s main office building but also significantly improve operational efficiency and safety. By upgrading the rail system, the Mill can now rely on smoother and more efficient rail operations, reducing potential delays and maintenance costs. The enhanced infrastructure helps ensure that the Mill can maintain its high standards for quality and timely delivery of products.
The Mill has been a valued client of HEI for many years, and we are honored to continue strengthening this partnership. We understand the importance of these improvements to the Mill’s operations, and we are committed to supporting their success through reliable engineering solutions.

Q&A
How long have you been working in this service sector?
I got my first engineering job as an Engineering Intern in the summer of 1988, 36 years ago.
Describe your career journey; what led you to your career, and what inspired you to pursue it?
My dad was my inspiration. He was the Ramsey County Highway Superintendent for 30 years in Devils Lake, ND. In the 1970s and 1980s, there were not a lot of restrictions on bringing kids to job sites, so I traveled with my dad a lot to different construction projects and just fell in love with construction and heavy equipment. In the summer of 1987, I got a job laying sewer pipe for a contractor on a big project in rural Devils Lake. While working that job, I got to know the project engineer and inspector. After that, I decided to enroll in college that fall at UND and majored in civil engineering.
What is the most rewarding part of your job?
Making the health and lives of people better.
Describe the tasks and responsibilities that you provide for clients?
The bulk of my experience is focused on design and construction management of potable water supply and treatment infrastructure, wastewater collection and treatment infrastructure, and solid waste collection infrastructure. I think the most important thing is to find out what the client wants. During my first 10 years as an engineer, I spent a lot of time in the field working with Operation and Maintenance crews and learned that not everything is the same. Too often, people assume that something like a sewage lift station is always designed the same way. However, based on the needs and wants of the client, they can be very different. Engineers can incorporate features that simplify maintenance for the client. That’s why I prefer to meet with clients before starting the design process to understand what matters most to them.
What would you like people/clients to know about your service sector? There are no issues or problems so complicated that they cannot be solved.
What’s the best piece of advice someone has ever given you?
My dad told me to not listen to the advice that people were pushing at that time, which was: “Don’t ever change, you are perfect the way you are.” He told me that people are always a work in progress, and you should always strive to be better. A better person, a better father, a better husband, a better friend, a better engineer, etc. Good is not enough when you can be better, better is not enough when you can
be the best.

Q&A
What project at HEI are you the proudest of?
Great projects are born from great clients and I have been very fortunate to work with some amazing ones. A project that stands out to me, where I served as the project manager, is Phase 3 of the Trout Brook Stream Restoration Project (Trout Brook). We completed this project for the South Washington Watershed District (SWWD), along with project partners Great River Greening, the Minnesota Department of Natural Resources (MnDNR), Afton State Park, and Vail Resorts, Inc.
Located within Afton State Park and the Afton Alps Ski Resort, the project had two primary goals: to increase cold water aquatic habitat for trout and reduce sediment and nutrient discharge to the St. Croix River. The project included approximately 0.8 miles of stream assessment, a channel remeander of approximately 750 feet, vegetation management along the floodplain, and floodplain connectivity. It also incorporated in-stream features such as log and rock riffles, toe wood bank stabilization, and log structures for habitat. Our team also replaced existing culverts with a box culvert that was installed below the stream bottom with a series of large boulders within the culvert to create natural fish passage conditions.
This was a fun project for me because of the coordination with the project partners, and it involved hobbies that I’m passionate about: fishing and alpine skiing. A proud moment for the SWWD, the partners, and the entire Trout Brook design team was when the project was awarded Project of the Year at the 2023 Minnesota Watersheds Annual Conference!
Tell us about the projects you are currently working on.
I am currently working with the HEI design team on the Newton Avenue Sanitary Sewer Reconstruction Project for the City of Minneapolis, which involves reconstruction of approximately 553 feet of sanitary sewer. During the design phase, we discovered the sewer was installed over 15 feet of peat and organic soil. To cost-effectively provide a stable base to support the sewer infrastructure without removing the full depth of poor soils, our team designed a helical pile and steel I-beam support system to cradle the sewer and manholes. I find projects such as this one interesting when the design team needs to come up with out-of-the box solutions to cost-effectively complete a project.
What’s the best piece of advice someone has ever given you?
Work hard, be respectful and humble, and never burn a bridge along the way in your career. I have had multiple experiences where past coworkers or acquaintances have turned into clients. The world is a small place and you never know who, or what, is coming around the bend.
