Sweetwater Ranch Stormwater Main Replacement

Project History

The original stormwater main was constructed before the development of the Sweetwater Ranch neighborhood and connects southward into Holly Pond. In 2018, a sinkhole revealed significant deterioration in the pipe, requiring emergency repairs. While those repairs remain structurally sound and continue to function as intended, a new sinkhole later formed near the same area. Subsequent inspections determined that the original sections of pipe downstream of the 2018 repairs had advanced deterioration and were at risk of further failure. These findings prompted the need for a long‑term replacement solution to protect neighborhood safety and maintain reliable stormwater conveyance.

Project Goals

• Restore reliable long‑term stormwater conveyance through the Sweetwater Ranch neighborhood.
• Prevent future sinkholes and infrastructure failures by replacing damaged pipe segments.
• Protect nearby wetlands and steep slopes through careful pipe realignment and construction planning.
• Reduce impacts to residents by using installation methods that limit disturbance.
• Ensure the abandoned existing pipe is safely stabilized to prevent future voids or ground movement.
