Drainage in Pacific Beach, CA.
Drainage for Pacific Beach 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.
Why is drainage different in Coastal San Diego?
Coastal drainage focuses on hardscape runoff, patios, pool decks, and driveways shedding to the foundation. Surface drains and downspout extensions handle most of it.

How does Pacific Beach's climate affect this service?
Pacific Beach foundation work centers on 1950s-70s post-and-pier beach cottages with salt-rotted mudsills and plumbing-leak slab voids in the converted-condo and small-multi-family stock. Sand-substrate settlement is common within four blocks of the water.. Coastal drainage focuses on hardscape runoff, patios, pool decks, and driveways shedding to the foundation.
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.
