Peavine Creek Watershed Protection Demonstration Project

The project’s overall goal is to protect water quality within the Peavine Creek watershed by reducing erosion, slowing and infiltrating stormwater runoff, and demonstrating practical watershed management techniques that reduce sediment transport to the Truckee River.

Funding will support replacement of an undersized culvert and pedestrian bridge, installation of a series of Zuni bowls to slow and infiltrate stormwater, stabilization of approximately 0.7 acres of hillside with vegetation, and an interpretive exhibit that help visitors understand how thoughtful landscape design protects local water resources.

TMWA Benefit:

II. Watershed Improvements: The project addresses a documented erosion site within the Peavine Creek watershed where concentrated stormwater has degraded the hillside and transports sediment downstream during storm events.

III. Local Stormwater Improvements: The project replaces an undersized drainage crossing with green infrastructure designed to safely convey and manage stormwater. A series of Zuni bowls will slow, spread, and infiltrate runoff while reducing localized flooding and erosion. Together, these improvements are expected to manage approximately 977,554 gallons of annual stormwater runoff, improving stormwater performance through natural, low-impact design.

V. Rehabilitation of Local Tributary Creeks and Drainage Courses: The project restores watershed function at an eroding drainage crossing immediately downstream of the Peavine Creek Source Water Protection Area. By reducing sediment movement, restoring native vegetation, and increasing infiltration, the project improves the condition of a tributary drainage corridor before runoff continues downstream toward the Truckee River.

VI. Stewardship and Environmental Awareness: The project creates a permanent watershed demonstration landscape where visitors can experience green infrastructure integrated into a public garden. An interpretive exhibit will explain stormwater harvesting, Zuni bowls, watershed protection, and drought-tolerant landscaping, while the Society’s Education Coordinators incorporate the project into existing education programs and engage visitors throughout the year.
