Douglas County signs stormwater treatment agreement with NDOT for Lake Tahoe project

In the heart of Douglas County, under the bright lights of the county commission chamber, a significant discussion unfolded on March 6, 2025, focusing on a vital interlocal agreement with the Nevada Department of Transportation (NDOT). The meeting, led by Chairwoman Hales, centered around a project aimed at enhancing stormwater management in the Marla Bay and Pine Wild areas, both of which are adjacent to the pristine waters of Lake Tahoe.

Courtney Walker, the county's stormwater program manager, presented the details of the proposed project, which includes the construction of new stormwater treatment facilities at 550 Sierra Sunset Lane. This initiative is not just about infrastructure; it represents a concerted effort to improve water quality and address flooding issues exacerbated by runoff from Highway 50 and the steep terrain of Zephyr Heights. Walker emphasized the importance of this project in meeting the Tahoe Maximum Daily Load (TMDL) requirements, which mandate that jurisdictions around the lake take specific actions to protect its clarity and health.

The proposed agreement outlines several key components: the acceptance of a conservation easement from the Patrick K. Willis Family Trust, an access easement from the Pine Wild Condominium Homeowners Association, and the authorization for the County Manager to sign necessary documents once conditions are met. Walker highlighted the collaborative nature of the project, noting partnerships with private landowners and local organizations to ensure effective stormwater treatment.

As the discussion progressed, Walker detailed the anticipated benefits of the project, including the potential for Douglas County to earn approximately 13.9 TMDL credits, which are crucial for compliance with state water quality standards. The partnership with NDOT is particularly beneficial, as the agency will fund the construction while the county will handle ongoing maintenance—a strategic alignment given the county's current lack of dedicated funding for stormwater capital projects.

The meeting also touched on the financial implications of the project. Walker estimated that maintenance costs for the new facilities would be manageable within the existing stormwater division budget, ensuring that the project remains financially viable without imposing additional burdens on taxpayers.

As the meeting concluded, the commissioners expressed their support for the initiative, recognizing its potential to enhance water quality and mitigate flooding in the region. This project not only represents a step forward in environmental stewardship but also underscores the importance of collaboration among various stakeholders in preserving the natural beauty and health of Lake Tahoe for future generations.
