Sump Pumps & Yard Drainage in San Mateo
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.
When a yard is lower than any outlet, an exterior sump basin collects the water and pumps it to an approved discharge point.
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.
Exterior sump basins, French drains and catch basins that collect water in low spots and side yards and move it away from your house.
| Sump basin with pump | Gravity French drain | |
|---|---|---|
| When it fits | Low spots with no downhill outlet | Yards that can slope to an outlet |
| How it moves water | Pump lifts water to the discharge point | Gravity carries water along the pipe |
| Power | Needs an outdoor power source for the pump | No power needed |
| Upkeep | Check the pump and float before the rainy season | Keep inlets and outlet clear |
We look at where water collects, where it comes from and where it can legally go.
We pick the mix of French drain, catch basins and sump basin for the site.
We trench and dig the basin location with the right fall toward the outlet.
We set the basin, pump and pipe in drain rock and fabric, and connect the discharge line.
We run water through the system, check the pump cycles and restore the surface.
If the drain line runs under the sidewalk to the curb, yes. San Mateo lists sidewalk underdrains among the work that needs an encroachment permit.
FEMA's revision effective October 11, 2024 removed about 1,600 addresses in North Shoreview and North Central from the flood zone. Check your address with the City.
We focus on exterior yard and side-yard systems. Interior work that needs new electrical circuits is for a licensed electrician or plumber.
