Due to the Tubbs Fire , many of the surrounding neighborhoods were destroyed , along with some of the coastline of the lake . A water storage tank was proposed near the southern end of Fountaingrove Lake ; the city of Santa Rosa has approved this project to add to the municipal drinking water supply , subject to erosion control measures to protect Fountaingrove Lake from excessive siltation . A substantial retirement community known as '' Varenna '' is under development as of 2007 on the ridgetop at the southeastern perimeter of Fountaingrove Lake . The '' Varenna '' project had not made wetlands mitigation environmental filings in a timely manner with the California Regional Water Quality Control Board regarding certain filling of perimeter wetlands of Fountaingrove Lake associated with its development project ; therefore , additionally off-site mitigation was required of the project to compensate the people of California for the wetlands destruction at Fountaingrove Lake . On site mitigation measures include extensive erosion protection for cut slopes and installation of bioswales
