Decks, Retaining Walls and Structural Work in Glendora
Ember-resistant decks, retaining walls and footings in Glendora, where parts of the city sit in mapped fire hazard zones and stricter rules may apply.
We look hardest at the underside of a deck on a Glendora property. Some sections of Glendora are mapped as fire hazard zones. On a lot inside one, ember-resistance rules may reach the deck surface, its framing and the open space beneath it. Inland exposure to strong sun and dry gusts also wears on boards and fasteners over time. Footings, posts and the area under the frame are planned with both pressures in mind.
Framing and surfaces that resist embers
In a mapped hazard zone, decking may need to be a noncombustible material or a rated product that passes the state test for ignition. Heavy timber or steel posts and beams can be specified where the code calls for them. The space under a raised frame is either enclosed with approved materials or kept clear of stored items and dry growth. Gaps between boards, vents near the deck and the wall where the ledger attaches all get looked at, since embers lodge in small openings.
Walls and footings below the deck
If the yard drops off past the house, a retaining wall may be needed to create level ground for posts or a patio. Block or poured concrete walls rest on reinforced footings, with gravel and perforated drain pipe behind them to relieve water pressure. The engineer sizes each pier from soils data and the expected load. The city building department reviews both the wall and the deck framing. Projects in Covina, San Dimas, La Verne, West Covina, Monrovia and Walnut are planned with the same steps.
