Water main break at Sandstone Hills Drive/Windmill Drive intersection
SPEARFISH, SD (September 26, 2022) - Early Saturday, September 24, the water main broke in two locations, both near the intersection of Sandstone Hills Drive and Windmill Drive. The section of water main with the breaks has been isolated and shut down. Those affected by this shutoff have been notified and alternative accommodations made. The area has been fenced off while it dries out.

Please stay out of the area as it is unsafe. Repairs will begin on Monday, September 26, after the area dries out some and the trench has stabilized some. Additional water shutoffs will be required during the repairs, and those affected will be notified directly. The repair work may extend the closure of the intersection until the repairs and temporary surfacing are complete.
The contractor plans to continue paving operations on Windmill Drive this week. The City and the contractor will work together to expedite the repairs, opening of the intersection, and completion of the project as much as we can. More information will be sent out once a more accurate timeline can be established after the full extent of the damages are assessed.
If you have any questions, the City of Spearfish Public Works Department at (605)642-1333. If you experience a water outage after hours, contact Dispatch at (605)642-1300.
We apologize for the inconvenience and thank you for your patience.

Update - Sandstone Hills Drive sanitary sewer main upsizing project
SPEARFISH, SD (July 29, 2022) - The contractor at Sandstone Hills Drive has experienced numerous delays while working on upsizing the sanitary sewer main.
There is large number of utilities in this location that makes working in this area difficult and tedious. The gas line was directly over portions of the sewer main and will need relocated. The watermain was at an elevation that conflicted with the new upsized sewer main. After re-aligning the watermain we experienced a water main break under Colorado Boulevard. The soil conditions in combination with the depth of the sewer main has made excavation challenging and hazardous. The contractor will be changing their excavation methods to make the work safer for their employees. This will result in an increased amount of construction traffic as they haul material off and on the project.
A new watermain will need to be bored under Colorado Boulevard. This will result in Sandstone Hills Drive continuing to be closed. Once we have an estimate on when materials will be delivered and schedules for a subcontractor to bore the casing pipe under Colorado Boulevard, we will have a better estimate of when this work will be completed and re-opened to traffic, but this could result in the closure of Sandstone Hills Drive continuing into the fall.
The contractor will work to accelerate the work on Windmill Drive and plan to start the mill and overlay in the next few weeks. Then progress over to Iron Horse Loop to complete the work on that route.
The intent is that the contractor will still complete all of the work this fall, just not in the order originally planned.
We appreciate your patience while the contractor works through these challenges. Additional notifications will be sent out as the work progresses and we have updated timeframes for when traffic configurations will be changing.
