Puff Lane Sediment Reduction Project

Overview
Spye General Engineering was contracted by Sonoma Resource Conservation District (SRCD) to implement this roads project in the burn scar of the 2020 Glass Fire. With funding from State Water Resource Control Board’s 319(h) program, Spye General Engineering’s crew worked under SRCD project manager Kevin Cullinen to replace 1 rusted and undersized ditch relief culvert, install 5 new ditch relief culverts, construct 4 rolling dips and 3 critical dips, armor two stream crossing inlets and outlets, and replace 1 rusted and undersized culvert with a new 71”x47” arched pipe on the road’s largest stream crossing. Combined, these treatments will serve to reduce the maintenance necessary upkeep the road while also reducing sediment inputs to the local watershed caused by road-related erosion and the resulting sediment transport into local streams.
