On Your Lot
The slab on your property follows the usual steps. Remove the old concrete, grade and pack the base, set forms and steel, then place, finish, joint and cure. Get each step in the written estimate.
At the Street
National City's Engineering Division has a permit form for public improvements. It lists residential driveways, sidewalk, curb and gutter, alley aprons and retaining walls, each as new or remove and replace. Driveway work at the curb runs through that Engineering permit.
The same form asks for a bond equal to 100 percent of the cost estimate before a permit is issued. It also asks for a deposit of 3 percent of the cost estimate or $5,000, whichever is greater. Ask the contractor how they handle this before you sign.
Who Can Do Street Work
State guidance says a General Engineering (A) contractor may do concrete work that is part of public works like roads. Some cities want that license for right of way jobs. Ask the contractor which license covers the apron, and ask the city.
Soil
County records list expansive clay soils across the coastal plain. Clay swells and shrinks with water. Base prep and joints are how a good crew plans for it.
