Retaining Walls in Glendale, AZ

Retaining walls are a different conversation in Glendale than in the foothill cities, because most of the town is genuinely flat. The central and south side near historic downtown, Catlin Court and Rovey Farm Estates sits on level West Valley floor, so here the walls are usually about definition and seating rather than holding a hillside: low seat walls that ring a patio or wrap a fire pit, and raised planter walls that frame desert beds. Push north into Arrowhead Ranch, Arrowhead Lakes and the communities near Thunderbird Conservation Park, though, and the ground picks up gentle grade off the Hedgpeth Hills, where a wall does real structural work.

On those north-side lots, the desert makes a modest slope harder to hold than it looks. Caliche and clay shed water instead of absorbing it, so when a monsoon dumps an inch in an hour, that runoff moves downhill fast toward the Skunk Creek drainage and scours any unsupported grade. A retaining wall on an engineered footing holds the grade, and the drainage gravel and perforated drain we build behind it give the water a path out instead of letting hydrostatic pressure push the wall over. That drainage is the part you never see and the part that determines whether a wall lasts.

Even on the flat lots, water is the reason seat and planter walls still need to be built right. We set every wall on a compacted footing, lay the first course dead level because every course above depends on it, and build up in concrete block sized to the height and load. Finished to match your pavers or travertine, a seat wall adds built-in seating around a patio or fire pit without furniture, and a planter wall frames the raised xeriscape beds that thrive on the West Valley floor. Because we self-perform the surrounding hardscape, the wall ties straight into the patio, turf or outdoor kitchen rather than looking tacked on.

Taller walls and any real terracing in north Glendale get reinforcement and, where the height calls for it, engineering to meet code, and the City of Glendale permits retaining walls above a set height and some drainage work. Arrowhead Ranch and Arrowhead Lakes also review wall height, color and materials before you start, while many older central and south-side lots have no HOA. We handle the engineering and the submittals both. Most residential walls run about 1 to 3 weeks depending on length, height and excavation, and we have built them across the Phoenix metro since 2012 under ROC 359628.
