Drainage in Casa de Oro, CA.

Drainage for Casa de Oro homes, done by an experienced San Diego County foundation crew. Almost every foundation problem in San Diego County has water in the story somewhere. Expansive clays swell when wet and shrink when dry, fines wash out under slabs, and hillside lots collect uphill runoff against the foundation.

Casa de Oro: Casa de Oro is unincorporated East County with mid-century ranch and newer custom stock. Original 1960s-70s post-and-pier raised foundations need cripple wall and seismic retrofit work; the 1990s-2000s custom builds see hillside perimeter settlement on the steeper lots.

Why is drainage different in East County San Diego?

East County drainage is event-driven. Long dry stretches, then 4-inch-in-24-hour storms. We size for the storm, not the average. Daylight discharge wherever the lot allows.

Do I need a permit for drainage work?

Most surface drainage and downspout work in San Diego County does not require a permit. Discharge to a public right-of-way (curb, gutter, alley) often requires an encroachment permit. We pull whatever is needed and coordinate with the city or county.

Sump pump or daylight, which is better?

Daylight every time, when the lot allows. No power, no maintenance, no failure mode. Sump pumps are reliable but they introduce a single point of failure, an annual maintenance task, and a power dependence. We design for daylight first and only add a sump when the lot will not allow it.
