Before and After Project Photos
Road Ripping and Decompacting
Before: Compacted road surface prior to decommissioning
After: The road bed has been hydraulically ripped to decompact the soil, improving infiltration and speeding revegetation
Cross-Road Drain Installation
Before: Native surfaced seasonal road prior to decommissioning
After: Road had been ripped (deocmpacted) and a cross-road drain has been installed to disperse runoff and prevent erosion
Stream Crossing Decommissioning
Before: Looking down towards the road from above the right sideslope of a culverted stream crossing
During: An excavator is used to remove fill from the crossing and re-establish the natural channel gradient
Two years later: Road related fill has been excavated and endhauled to a stable location
Road Outsloping in the Santa Cruz Mountains
Before:The combination of an outboard berm and insloped road surface hampers road surface drainage
After: Outsloping and berm removal improves road drainage, disperses runoff, and reduces road surface erosion
Improving Road Surface Drainage with Rolling Dips
Before: A long reach of insloped, bermed road discahrges runoff & fine sediment to the inboard ditch & to nearby watercourses
After: Installation of a rolling dip disperses runoff towards the outboard edge of the road and improves road surface drainage
Rocky Gulch Road Decommissioning and Fish Passage Barrier Removal
Before: Legacy streamside logging road in Rocky Gulch was reopened for heavy equipment restoration work
After: Road fill has been excavated from the stream channel and riparian habitat has been restored
Road and Landing Fillslope Instabilities - Decommissioning
Before: Abandoned road on the steep inner gorge slope of a salmonid stream has been reopened to excavate unstable fillslopes
After: Unstable road fill has been excavated and hauled off-site. Exposed surface has been mulched with alders, brush and straw
Road and landing fillslope instabilities - Decommissioning
Before: Unstable streamside road reach with high potential for sediment delivery
After: Unstable fill has been excavated and endhauled, and mulch has been applied to protect bare soil
Stream Crossing Decommissioning - Bridges
Before: Railroad flat-car bridge with old-growth redwood abutments
After: The bridge has been removed and unstable fill has been excavated from the channel sideslopes
Landslide Excavation - Decommissioning
Before: Active landsliding along this poorly designed road threatens to deliver sediment to the stream below
After: A combination of endhauling and in-place outsloping have been used to decommission this unstable road reach
