Document Title
Rhys Vineyards Road Network Upgrades Project
Document Type
NOE - Notice of Exemption
Document Description
The purpose of this Project is to address identified controllable sediment sources discharging from the road network to watercourses as required per Attachment C, Item 4, of a settlement agreement between Rhys Vineyards, LLC and the North Coast Regional Water Quality Control Board (WR 2019-0053-EXEC). Stream crossings will be repaired by installing structures including trash racks and culverts or replaced with properly sized and placed culverts, bridges, or rocked ford crossings. Additional stream crossings will be decommissioned by removing old, poorly functioning culverts, excavating and stabilizing residual fill material, and installing cross drains to hydrologically disconnect road segments. Project descriptions and designs include Best Management Practices and assurances that construction will avoid and minimize the threat of a discharge to waters of the state and minimize impacts to the bed bank and channel. Project crossings will be constructed to the 100-year storm requirements and will reduce existing fill impacts to channels where applicable. Work is expected to begin on June 1, 2021 and all work should be complete by October 15, 2024.
