A small foothill city below Angeles National Forest, where a contractor needs written owner authorization.
Small city, foothill ground, and properties where a deck is usually taking real advantage of the position. Sierra Madre has 5,095 housing units with 61.4 percent of the occupied ones owner occupied, in the foothills of the San Gabriel Valley below the southern edge of the Angeles National Forest.
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.
The other 38.6 percent of occupied units are rented, so shared walkways and open stairs turn up alongside private decks. Those fail in the traffic lane first, at doorways and the head of the stair, and the water that gets in tracks along framing until it exits somewhere that looks unconnected.
On foothill lots the underside is where the honest information is. Ledger condition, hardware section, whether the posts have been standing in wet ground: none of that shows on the finished surface, and all of it decides whether we are quoting a surface rebuild or replacing framing.
Where a stair run has gone past sensible repair we fabricate and set a new one in iron or precast rather than patching a structure people use every day. On sloping property that is often better value, because a rebuilt run can correct the landing drainage that caused the failure.

Sierra Madre sits in the foothills below the southern edge of the Angeles National Forest, so storm water arrives quickly. A deck that sheds without a collection path is feeding the ground around your foundation.
