Big Daily Temperature Swings, Small Daily Damage

Tarzana has a hot summer Mediterranean climate and, because of its inland position, a higher degree of daily temperature variation than the more coastal parts of Los Angeles. That daily swing is the mechanism behind most of the deck failures we see here. The surface expands and contracts, and the movement concentrates at the same places: the edge, the railing post, the joint where the deck meets the wall.

Nothing about that is visible until water shows up to use the openings. It is also why we spend the time on details rather than square footage, because the field of a deck is rarely where a failure starts.

Tarzana covers 8.79 square miles, bounded by Topanga State Park to the south, Encino to the east, Reseda to the north and Woodland Hills to the west, and at 4,038 people per square mile it has among the lowest population densities in the city. That means spacious single family property and larger decks.

The south end backs onto parkland rather than more valley floor, and property against open ground has its own drainage picture. Water arriving from outside the lot has to be routed past the structure, not across a deck that was never designed to carry it.

On larger decks, movement is the design problem. A long span works its terminations every day of the year, so joints, transitions and penetrations get built to accommodate that rather than sealed shut and expected to hold.

Waterproofing in Tarzana: Your Questions

Why does inland Tarzana wear out decks faster than the coast?

The neighborhood has a hot-summer Mediterranean climate with a higher degree of daily temperature variation than more coastal parts of Los Angeles. That daily expansion and contraction is what opens edges and penetrations.

Are the properties here bigger than average?

Generally yes. Tarzana runs 4,038 people per square mile across 8.79 square miles, among the lowest population densities in the city, so decks tend to be larger and spans longer.

Which department handles permits for Tarzana?

The Los Angeles Department of Building and Safety, since Tarzana is part of the City of Los Angeles. LADBS handles plan review, permitting, inspection and enforcement, and we file and carry the inspections.
