A small foothill city below Angeles National Forest, where a contractor needs written owner authorization.
Sierra Madre sits in the foothills of the San Gabriel Valley below the southern edge of Angeles National Forest, with 5,095 housing units and just over 61 percent of the occupied ones owner occupied. Small city, foothill ground, and properties where a deck is usually taking real advantage of the position.
Being that close to the forest edge means runoff arrives fast during storms and the rest of the year the sun works on the surface without much shelter. Both matter, but drainage matters more. A deck that pushes water toward a foundation on sloping ground is creating a problem the coating will get blamed for later.
