Elevation Certificates in Elk Grove: Local Conditions

Elk Grove's mapped flood hazards come from its creeks and from the Cosumnes River. FEMA's Flood Insurance Study for Sacramento County lists Elk Grove Creek, Laguna Creek, the Laguna Creek Bypass Channel, Laguna Creek Tributary No. 1 and Strawberry Creek in the city, along with Cosumnes River levees. The flood history is mostly about that water. In 1958 about 38,000 acres flooded along the Cosumnes and the lower reaches of Dry, Deer and Laguna Creeks, and in 1997 the Cosumnes broke through levees in 24 places. The same study gives Elk Grove the widest set of zone types of any city in the county: A, AE, AO, AH and X. That matters for an EC, because an AO lot is rated on flood depth while an AE lot has a base flood elevation.

Laguna Creek runs through the middle of town. The City's Laguna Creek Restoration and Management Plan covers a 1.75-mile reach from the Bond Road and Waterman Road intersection downstream past Bond Road and Elk Grove-Florin Road, and it balances habitat and recreation against reducing flood risk. Public Works will give you a property's FEMA zone, community number, panel number, panel effective date and any LOMR on file. Bring the address or parcel number. The City reviews residential building in a floodplain case by case, so talk to Public Works early if you plan to build or add on near a creek.

An Elk Grove elevation certificate starts with a benchmark tie on NAVD88, the vertical datum of the Sacramento County FIRM. Then we measure lowest adjacent grade, the top of the lowest floor, the garage slab, and machinery such as HVAC units and water heaters, photograph the building, and certify the EC. If the survey shows grade at the structure at or above the BFE, a letter of map amendment may remove the lender's insurance requirement, and we can submit it through eLOMA when it qualifies. See our elevation certificate service, nearby Galt and Sacramento pages, or our Elk Grove area page.

Our Process

Address & Flood Map Check

Send the address and the reason you need the certificate: lender letter, insurance quote, building permit, or a LOMA. We pull the effective FIRM panel, flood zone, and Base Flood Elevation before quoting, and tell you up front if a LOMA looks possible.

Benchmark Tie

We tie the site to a published benchmark on the vertical datum the flood map uses, with GNSS and a total station. Every elevation on the certificate is measured from that tie, not estimated from a contour map.

Building Measurement

We measure the top of the bottom floor, the next higher floor, the garage slab, the lowest and highest adjacent grade, the lowest machinery and equipment, and the flood openings, and take the photographs the form requires.

Signed EC, and the LOMA if It Qualifies

You receive the completed, signed Elevation Certificate as a PDF. If the lowest adjacent grade is at or above the Base Flood Elevation, we prepare the LOMA request and submit it to FEMA, through eLOMA when the building meets its criteria.

Elevation Certificates in Elk Grove: FAQ

Check the FEMA Flood Map Service Center, or call Elk Grove Public Works with your address or parcel number. They will give you the FEMA zone, community number, panel number and effective date, plus any Letter of Map Revision issued for the property. If the zone is A, AE, AO or AH, a lender with a federally backed loan will require flood insurance.

Somewhat. Zone AO is shallow flooding with a depth number on the map instead of a base flood elevation. The EC still records lowest adjacent grade, the lowest floor and machinery, but the comparison is height above grade against the mapped depth. We fill in the sections that apply to AO and note the depth from the FIRM.

Often it can. If the lowest ground touching the house is at or above the base flood elevation, FEMA can issue a LOMA saying the structure is outside the Special Flood Hazard Area. FEMA charges no review fee for a LOMA. We survey the lowest adjacent grade and file through eLOMA when the request qualifies.
