In 2018, the City of Brandon selected DGR Engineering (DGR) to assist the community with the reconstruction of approximately 30 city blocks of the Rushmore Area in the southeast part of the city. The streets had outlived their useful life and the roadway was starting to degrade quickly in certain areas. Part of the reason for the rapid degradation of the street surface was the lack of storm sewer in the neighborhood. In addition, the water and sewer lines were in need of replacement due to their age and condition. Additional storm sewer, new curb, gutter and asphalt pavement, as well as a new 4 ft. wide sidewalk and ADA improvements, were also included.

The first steps in the process were to survey the entire project area, coordinate with staff to define the scope, and develop cost estimates for the work that needed to be done. Potential project phases were developed for the project to meet the financial needs of the City. Phasing of the project that would best fit the City's budget was determined, and then DGR began to design the first phase.

Communication was critical to keep residents informed. Letters were mailed out to residents prior to a survey taking place. A public open house was held to give residents details of the project and inform them of easements that would be needed. Easement documents were prepared and sent to property owners. DGR conducted many personal meetings with residents to discuss and obtain easements to facilitate the project.

DGR designed a new lift station, new sanitary sewer, water mains and the associated service lines as well as a storm sewer system to collect stormwater. The stormwater was routed to the south end of Rushmore Drive to the sedimentation basin designed as part of the project. The sedimentation basin has a system in place to help collect trash washed from the streets and to contain sediment and oils from the roadway. This allows the City to collect that material and dispose of it, rather than have it carried into Splitrock Creek.

DGR teamed with Confluence to facilitate streetscaping and the sedimentation basin landscaping.

The sedimentation basin was a unique feature to this project. It was designed to slow the discharge of stormwater to Splitrock Creek in smaller rain events, but it also has the ability to be overtopped at the bottom in larger rain events without causing damage to the system. As the City of Brandon grows, the basin will help to meet upcoming MS4 (Municipal Separate Storm Sewer System) EPA requirements that will be placed on the City.

DGR assisted the the City in acquiring the land needed to construct the sedimentation basin and relocate the City’s lift station that serves the area. The decision was made to relocate and construct a new sanitary sewer lift station on the same parcel that would contain the sedimentation basin. The new lift station replaced some aging pumps and equipment, and employees will no longer need to climb down into a confined space. In addition, an on-site back up generator was added to provide instant backup in the event of a power outage.

During construction, DGR provided on-site construction observation to ensure the work complied with the design requirements and to work with residents, answer their questions and address their concerns. Temporary mailboxes were added near the post office for the project and when the project was complete, Cluster Box Units (CBU’s) were installed, eliminating mailboxes at each residence.

Phase II is planned to be constructed in 2023 and Phase III construction is planned for 2025.

Infrastructure Improvements

The infrastructure investment will significantly improve and benefit the community and all residents with many years ahead with reliable infrastructure.

Water Treatment Plant

The building is expandable to add future treatment equipment that can double the treatment capacity as water demands increase in the future. With three times more water available and enough annual water appropriation to operate at full capacity all year long, the new facility has become Red Rock’s primary water source.

Water System Improvements

The water tower serves as both a critical piece of Sheldon’s drinking water infrastructure and as a welcome beacon for the City.

Drainage Channel Improvements

DGR designed the channel to handle more capacity and protect the area from future flooding, which required making the channel deeper and wider.

Athletic Field Site Design

Project planning by Augustana University and DGR Engineering to upgrade Bowden Field to a championship level began in 2018, and eventually culminated in a new facility which opened for the 2023 season.
