The Marin County Deputy Zoning Administrator will hear a Bolinas resident’s application for a coastal permit today to build an underground concrete pier wall and beams to strengthen the bluff under the cliffside Terrace Avenue property. The emergency repair results from ongoing slides that have exposed four feet of the home’s concrete foundation, on the southern corner. The slope is continuing to erode, threatening the stability of the home, which was built in 1962. A biologist’s report found that the project would not significantly impact wildlife habitat; it would have minimal visual impacts, and the support column would need to be earthtone in color, according to a staff report. Marin County project planner Lorene Jackson said that she knew of no other coastal permit applications for other homes in the area.
