Foothill city below the San Gabriels, split almost evenly between owners and renters.
Monrovia sits in the foothills of the San Gabriel Mountains in the San Gabriel Valley, with 15,241 housing units and occupied housing running close to an even split between owners and renters. So the work alternates between single family decks up on the slope and shared walkway and stair repairs on multi unit buildings further down.
Foothill ground gives water speed. On the higher properties a deck has to direct runoff somewhere deliberate, because water simply shed off the edge ends up against a foundation or working into a slope. That drainage decision does more for the life of the repair than the product choice does.
