Retaining Walls, Decks and New Homes in Sylmar
Ember-resistant decks, retaining walls and new homes in Sylmar, detailed for inland valley wind and sun, with drainage planned before any footing.
Across the inland valleys, dry seasonal wind drives more building choices than heat or rain, because it carries embers ahead of a fire, pulls moisture out of wood and pushes grit into every open joint. A Sylmar house, deck or retaining wall is detailed for that regional pattern: boxed eaves, screened vents, sealed lumber ends and tight trim. Sylmar also includes parcels on mapped fire hazard maps, which turns several of those choices into code requirements.
Ember-resistant construction
On a parcel inside a mapped fire hazard area, the code adds requirements for new homes and additions. Siding has to be ignition resistant, which points to stucco or fiber cement. Eaves are enclosed with noncombustible soffits, and attic and crawl space vents use a fine metal mesh or a listed ember baffle. Exterior glazing is often dual pane with at least one tempered layer. A deck attached to the house uses rated boards, and the space below it stays open and clear or gets enclosed. We confirm the parcel's map status before anything is drawn.
Drainage drawn before the foundation
Hard ground after a dry stretch sheds water fast, and a footing or retaining wall suffers when runoff pools against it. Our plan starts at the roof: gutters sized for heavy bursts, and downspouts piped in solid lines to the street or to an approved outlet. A shallow swale on the uphill side, if the yard has one, intercepts sheet flow before it reaches the walls. Behind any retaining wall goes a perforated pipe bedded in gravel wrapped in fabric. Projects in Pacoima, Lake View Terrace and Arleta are laid out on that same drainage plan.
