Wastewater Treatment Facility (Last Updated 4/3/19)

We are in the process of building our own wastewater treatment facility. During the past few months we’ve been selecting our team of consultants to assist us in this endeavor. The project is currently in the design phase and we are scheduled to break ground in the fall of 2019 with construction occurring until spring of 2021. Facility start up will occur during the summer of 2021. In the fall of 2021 our wastewater ponds 1 and 2 will be decommissioned and pond 3 will then only be used during high flows and emergencies.

Our consulting design engineering firm is nearing 30% plans completion. We had our first meeting with our construction management team yesterday.

Staff has been investigating cost effective, short term solutions to combat odor issues at our lagoons for the next couple years until the facility is up and running. We realize the odor can be extreme sometimes. Please bear with us during this transition.

Sidewalks & Trails (4/1/19)

Plans are nearly complete for a sidewalk along the north side of Willow St from Liberty Elementary to the High School. Construction could occur later this year.

An additional sidewalk/trail project has been identified in the vicinity of the Middle School. The schedule of this project is contingent on the budget.

Staff is taking inventory of streets without sidewalks and locations of sidewalks in need of repairs and ADA improvements. After compiling this data, we will be working with our city boards and community organizations to prioritize the improvements. Then, a long term plan will be developed. Funding these improvements will likely dictate the schedule of installation.

Road Condition Survey (4/1/19)

This summer a road condition survey will be conducted by a third party vendor using state of the art technology. If you see a van with a bunch of strange equipment mounted to it, it’s likely them. This will provide information of the surface condition of all streets, structural condition of collector streets, and inventory our curb and gutter condition. This will help us immensely in prioritizing our street maintenance and repair plan.

Arterial Street Funding Study (4/3/19)

An arterial street funding study for our city will be conducted this summer by a specialized engineering consultant. This is vital step in the long and complex process of determining how to pay for our arterial streets.

Anna Way & Perry Ave (4/16/19)

In consideration of the recent rain events, we have decided to put the planned Anna Way/Perry street reconstruction project on hold. We are now evaluating short term and long term drainage solutions for this area. We have now engaged an engineering consultant to assist us in determining an engineered solution to drainage in this area.

In the meantime, we plan to asphalt patch areas that are in poor condition in the vicinity of the Anna Way / Perry intersection as soon as asphalt is available, likely sometime in May. Funding for this project was approved by City Council on 4/15/19.

Southeastern Ave from Willow St North to Legendary (4/16/19)

Millings were applied today to segments of the road that are in poor condition as a temporary fix. Vehicle weight limits remain in affect. Later this summer, this portion of the road will undergo subgrade reclamation/regrade/compact and then apply a new asphalt mat. Funding for this project was approved by City Council on 4/15/19. We have also engaged an engineering consultant to assist us in determining an engineered solution to drainage in this area.

Cliff Ave and Willow St Intersection (4/1/19)

This intersection is owned jointly by the Harrisburg and Lincoln County. Harrisburg recently conducted a traffic study of the high traffic intersections in Harrisburg, including this one. We are planning to conduct additional detailed traffic studies of these roads later this year and Lincoln County is currently conducting a Transportation Master Plan. Once the study is completed later this summer, we use this data to determine the best path forward for this intersection.

Central Park (4/1/19)

The grading and storm sewer installation of phase two of central park (north of Liberty Elementary) is expected to be completed this year. The long term schedule to complete this park is still up in the air due to many variables, including our budget.

Projects of Interest by Others

Highway 115 Reconstruction (SDDOT) (4/4/19)

This is a 2 year project. In 2019, Highway 115 (Minnesota Ave) from just south of the intersection of Highways 115 and 110 (Minnesota Ave and Willow St) north to Cardinal Pl (just south of 271st St) will be completely reconstructed. In 2020, reconstruction will occur from Cardinal Pl to 85th St.

The southern portion of the 2019 project, from just south of the intersection of Minnesota Ave and Willow St to the apple orchard will be closed from about April to about September. The remainder, from the orchard to Cardinal Pl will be closed from about September to about November. The intersection of Minnesota Ave and Willow St will be closed this summer for 40 days. This will likely not occur all at one time. The exact closure dates are not yet known.

As soon as we have any additional information, we will disperse it to you via our city website and/or our Facebook page. For the most up-to-date and accurate information, please contact the DOT directly. The road closures will be an unavoidable inconvenience for a while. Please allow yourself extra time for travel in consideration of this.

*Starting Friday at noon on April 5, this project will be delayed and the road will be reopened until weather conditions improve.*

Lincoln County Master Transportation Plan (Lincoln County & SDDOT) (4/1/19)

Lincoln County and SDDOT are currently studying the county road system to prioritize improvements in response to the rapid growth. This report is expected to be completed this summer. The information from this study will assist Harrisburg immensely in our future transportation planning, including improvement alternatives for the Cliff and Willow intersection.
