On June 18, 2025, the Timberline Valley South HOA completed a shoreline repair project along their detention basin adjacent to Erin Drive. HOA’s are responsible for the maintenance of the common areas within their bounds, including the detention basins. Shoreline erosion can reduce a basin’s ability to store water, and the loose sediment feeds algae and make the water murky which can impact the basin’s ecology. The HOA submitted a small grant application to help cover the costs of the repair work.
