Road systems are perhaps the most significant and easily controlled sources of sediment delivery to stream channels
General Info
To address erosion from existing unpaved roads, Napa RCD has adopted an approach to work with landowners and managers to prevent erosion through improved road maintenance practices. Specific road maintenance practices can immediately benefit streams and aquatic habitat by reducing sediment delivery from the road system, detaining flows to provide opportunities to recharge the groundwater system and reducing annual road maintenance costs. Check out the RCD’s Storm-Proof Roads Checklist.
How can I get involved?
Napa RCD staff can work with private and public land managers to assess erosion sources, develop improvement plans, and oversee implementation and operation of heavy equipment. Cost-share for this service may be available or Napa RCD may perform work as “fee-for-service”.
