Sump Pumps & Yard Drainage in San Mateo

What San Mateo homeowners should know

Flat lots near the Bay

North Shoreview and North Central sit on low, flat ground. About 1,600 addresses came off the FEMA flood map in October 2024 after levee and pump upgrades, but heavy storms still leave water standing in flat yards.

Sump basins where gravity fails

When a yard is lower than any outlet, an exterior sump basin collects the water and pumps it to an approved discharge point.

Sidewalk underdrains need a permit

Running a drain line under the sidewalk to the curb is public right-of-way work, and San Mateo requires an encroachment permit for sidewalk underdrains.
