South Natomas and North Natomas are different jobs
South Natomas was built out in subdivisions from the 1950s through the 1980s. Driveways and walkways from that era are often the original slabs, so the likely jobs are concrete repair, leveling of sunken sections, and tear-out and driveway replacement when cracking has spread across the whole pad.
North Natomas is much newer. Development there was restricted from 1990 to 1998, then a 100-year flood certification in 1998 opened rapid building. After the 2008 FEMA remap, a building moratorium began in December 2008 and was lifted in 2015. Homes in North Natomas therefore span a wide range of ages for one neighborhood, and the work people ask about tends to be additions to a new lot: a patio, a widened driveway, a side-yard walkway or a pad for a shed or hot tub.
City of Sacramento driveway rules apply
Because Natomas is inside the City of Sacramento, the city's driveway permit instructions (form DE-308) govern the approach where your driveway meets the street. Confirm current requirements with the city before work begins. What the form says:
- No permit is required for driveways that abut a rolled (mountable) curb or an alleyway, though the driveway still has to meet code.
- A Driveway Permit is required for a new or modified driveway that needs an inlet, meaning a curb cut.
- An Encroachment Permit applies when you reconstruct an existing driveway inlet without changing its width.
- Width is 10 to 12 feet for a single-car driveway and up to 20 feet for two cars, and length is 20 feet from the property line (18 feet in the Central City). No driveway may be within 10 feet of a pedestrian ramp.
- The application package includes a site plan, a traffic control plan and proof of liability insurance, with a fee that varies by driveway width. Work may begin only after the permit is issued.
On your own lot, the California Building Code exempts driveways and sidewalks not more than 30 inches above adjacent grade (and not over a basement or story below) from a building permit. Local sources describe flatwork in the city as generally exempt, but we could not confirm that on a city page, so ask the city. For walls, the state baseline is a permit above 4 feet from footing to top; we could not confirm a different city threshold.
Flood history and why drainage belongs in the conversation
Natomas's levee and flood history is why its building timeline looks the way it does. We have no source on Natomas soil type, so we will not describe it. What the history does justify is asking any contractor how they plan to grade the slab so water runs away from the house, and where roof and downspout water will go. Sacramento County in general has hardpan and clay layers that drain slowly, and the county's soil survey notes high shrink-swell in some soil series, so a slab's base preparation matters. Ask what base rock, thickness and joint spacing the contractor proposes. A common rule of thumb is control joints at 24 to 36 times the slab thickness, so a 4-inch slab gets joints about every 8 to 12 feet.
What to settle before the contractor visits
| Question | Why it matters in Natomas |
|---|---|
| Is the street-side approach changing? | A curb cut or inlet change triggers a city permit; keeping the existing approach may only need an encroachment permit |
| How old is the existing slab? | South Natomas originals are usually replaced; newer North Natomas slabs are often repairable |
| Who pulls the permit? | Ask the contractor to state it in the written scope |
| Where does the water go? | Grade away from the house; confirm downspout plans |
| License and class? | Check C-8 (concrete) at cslb.ca.gov |
Typical national price ranges, not Sacramento quotes: plain broom-finish driveways run about $6 to $12 per square foot installed and patios about $5 to $18. Quotes from local contractors will differ. The concrete cost guide explains what moves the number.
