Description:
A three-year project was conducted by the California State Water Resources Control Board to determine methods of preventing and correcting erosion problems which severely effect the quality of the waters of the State of California. Two-project sites were chosen in the vicinity of the Lake Tahoe basin in California. One project site, Northstar-at-Tahoe, is a well planned and constructed residential-recreational development constructed in the early 1970s. The cost of extensive predeveloped planning and erosion control at Northstar is currently less than $400 per developed unit or residential lot. With ultimate planned build-out, costs are expected to be reduced to $220 per developed unit. The other project site, Rubicon Properties - Unit No. 2, is an extremely poorly planned and constructed residential subdivision development constructed in the late 1950s and early 1960s. The cost of complete corrective erosion control at Rubicon Properties would range from $1,000 to $3,000 or more per residential lot. At both project sites, extensive demonstrations were made of predevelopment planning concepts, construction techniques, and corrective measures which may be used to substantially reduce erosion and sedimentation problems associated with developments which are typical to the subalpine to alpine Lake Tahoe region of California. Analyses were made to determine cost and effectiveness of the various erosion control techniques which were demonstrated at the project sites.
