Lost Canyons Development Modification & Open Space Expansion
Simi Valley
Summary
The developer of the 1,770-acre Lost Canyons project wants to remove the closed golf course and shift 178 approved homes from the south side of Lost Canyons Drive to the north side. While this increases open space from 43% to 89% and spares sensitive canyons from grading, neighbors raised heavy concerns about building more luxury homes in a high fire-risk area.
