Restoring the natural look of an area following a landslide or severe erosion repair can often rank just as high a projectpriority as the actual stabilization。 This paper presents a non-traditional biotechnical stabilization and restorationapproach using ballistic soil nails， galvanized steel mesh and native plant impregnated coconut fiber geocells in an areaprone to rotational slope failures along the western shore of Lake Tahoe， California。 Working within stringent TahoeRegional Planning Agency (TRPA) guidelines， the project produced a restored shoreline face with a walking paththrough a newly stabilized high bank waterfront property。 In addition to preventing further rotational failures， theapproach mitigated widespread surface erosion and sloughing of the shoreline face。 Traditional methods of mechanicalslope stabilization such as benching， shotcreting， or anchoring would have been effective at stabilizing the shorelinemovement and accommodating a new walking path。 However， those approaches would have substantially altered theappearance of the shoreline and would have been unacceptable to TRPA and the property owners。 In this case study，the benefits of biotechnical stabilization were crucial to the acceptance of the project。 A combination of ballistic soil nailsand custom vegetated mats both stabilized the existing rotational failure and provided anchorage points for thevegetated mats。 That concept allowed cuts up to six vertical feet in the unstable sandy silt shoreline material。 Workingclose to a protected lake and establishing plantings in the semi-arid Lake Tahoe environment presented real challenges，but a biotechnical stabilization system using mechanical elements and appropriate high mountain desert nativevegetation met both the structural and aesthetic demands of the project。
