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.
