The goal of the Zephyr Cove Water Quality Improvement Project is to treat sediment and nutrient laden stormwater flows from US Highway 50 by re-routing flows to an infiltration basin and safely conveying any overflow to Lake Tahoe while minimizing beach erosion. After many years of planning with multiple stakeholders and agencies, the design was finalized in 2016 and constructed in two phases, a 2016 Phase 1 and a 2017 Phase 2. Construction of the project was completed in June 2017 and the project is currently undergoing irrigation to establish vegetation. The project was funded by the Nevada Department of Transportation, the Nevada Division of State Lands, the Nevada Division of Environmental Protection, and the US Forest Service.
