Road Outsloping in the Santa Cruz Mountains

Before:The combination of an outboard berm and insloped road surface hampers road surface drainage
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
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
