Environmental Improvement Projects (EIP)

The Environmental Improvement Program (EIP) is a cooperative effort to preserve, restore and enhance the unique natural and human environment of the Lake Tahoe Region. The EIP program defines restoration needs for attaining environmental goals or thresholds and, through a substantial investment of resources, increases the pace at which the thresholds will be attained. Key to this strategy is reliance upon partnerships with all sectors of the community, including the private sector, local, state and federal government.

The EIP was initiated following the first Lake Tahoe Environmental Summit in 1997. Since its inception, over one billion dollars have been invested in projects to attain various environmental thresholds, including enhancing the clarity of Lake Tahoe.

The City of South Lake Tahoe is responsible for treating stormwater runoff from City-owned property and from the City’s public right-of-way (streets).  EIP funded public improvement projects focus on infiltrating excess runoff generated from paved surfaces, stabilizing road shoulder sediment sources, removing sediment from roadways through drainage systems, and trapping fine sediment and other pollutants carried in storm water runoff in treatment basins and other devices. 

Current EIP Projects

Sierra Tract Erosion Control Project, Phases 3 & 4

Project Manager: Stan Hill
Status: design
Schedule: 2015-2016

The Sierra Tract ECP, Phase 3 & 4 project includes design of water quality improvements for commercial portion of the Sierra Tract subdivision immediately adjacent to U.S. Highway 50 and the southwestern residential portion of the subdivision.  Storm water from the project area drains directly to the Upper Truckee River, which drains to Lake Tahoe. 

For more information, view the Project Workplan which includes a project description, detailed maps and analysis of the REDUCTION of fine sediment produced within the project area that flows to the Upper Truckee River.

Tahoe Valley Stormwater Improvement Project

Project Manager: 

Status: planning

The Tahoe Valley Stormwater Improvement Project includes much of the densely developed commercial areas near U.S. Highway 50, both north and south of the “Y”. The area is a priority for treatment as storm water runoff discharges directly to the Upper Truckee River, which drains to Lake Tahoe.  The project includes design of water quality improvements to reduce pollutant loads discharged to the Upper Truckee River.

The Tahoe Valley SWIP ties in with the Tahoe Valley Area Plan to reduce pollutant loading while creating a walkable, bikable and scenic connection from one of the more densely populated areas of the City to adjacent neighborhoods. The Tahoe Valley Area Plan is currently under review.
