About Santa Susana Hills
Most of the houses are in Unit No. 2. Unit No. 1 runs east toward Lookout Rock Trail and Santa Susana Pass Road, and Unit No. 3, along Live Oak Trail, is still mostly vacant. Amos F. and Helen B. Mortimer signed the maps with co-owners and a bank, and the maps did not dedicate their drives, trails and walks to public use.
