Slopes, canyon winds and brush on the edge of the hills
Roads such as Nohl Ranch Road and Santa Ana Canyon Road lead through the area, and the SR-91 and SR-241 are close by. Many streets climb or curve, and driveways can be steep, which affects where a dumpster, a delivery truck and a ladder can go.
Santa Ana winds often blow hardest in fall and winter and can lift tile edges or drop branches onto the roof. Dry canyon vegetation near some neighborhoods also raises wildfire concerns, so ember resistance matters on the roof and at the vents. Palm fronds, eucalyptus and pine needles can collect in valleys and gutters, and a clogged valley overflows under tile before the owner notices.
