Elevation Certificates in Dixon: Local Conditions

Dixon is flat. FEMA's Solano County Flood Insurance Study puts elevations in the city between about 40 and 70 feet and says that on average the town is very flat, with Dickson Creek falling only about 7 feet per mile as it crosses from northwest to southeast. Most of Dickson Creek inside the city runs through underground storm drains, which the study says can carry runoff from roughly a 10-year storm. Anything bigger runs over the streets and ponds behind natural or manmade barriers. Dudley Creek crosses the northeast corner of town. In flat ground like this, flood zone lines on the map can sit a long way from any visible creek, and small differences in grade, a few tenths of a foot, decide which side of a line a house falls on.

Dixon's recorded flood history is modest. The study reports minor flooding in December 1955, April 1958, and January 1965. In 1955 floodwater surrounded a few homes in a subdivision in the northwest part of town, probably with help from Dickson Creek overflow, though no damage was reported, and in 1958 a cloudburst left water standing in some streets. Flood control is local and small-scale: two ponding basins just north of Dickson Creek near West H and North Almond Streets collect subdivision runoff into the creek conduit, and a small basin sits on Dudley Creek. Dixon is FEMA community 060369 on the Solano County FIRM. For Dixon owners, the elevation certificate usually comes up when a lender's flood determination puts a house in a mapped zone, when a buyer wants to know the floor height before closing, or when a new building or addition in a mapped area needs certified elevations for the permit.

Our field work ties to NAVD88 benchmarks with GNSS, then a Trimble S3 total station measures the lowest adjacent grade, highest adjacent grade, the top of the lowest floor, garage or shop slab, flood openings, and HVAC and utility equipment. We photograph the building as FEMA requires and sign Form FF-206-FY-22-152. If the ground touching the structure is at or above the Base Flood Elevation but it is still drawn in the zone, we can prepare a Letter of Map Amendment and file it through eLOMA when eligible. Dixon is a scheduled mobilization from our base in El Dorado County, not a local office. See our elevation certificate page and the nearby Vacaville and Davis pages.

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 Dixon: FAQ

According to FEMA's study, most of Dickson Creek runs in underground storm drains sized for about a 10-year storm. Larger storms send water over the streets, where it ponds behind barriers. Check your parcel's mapped zone at msc.fema.gov.

Accurate enough that a few tenths of a foot are reliable, because on flat ground that can decide whether the lowest adjacent grade is above or below the Base Flood Elevation. We tie to published NAVD88 benchmarks with GNSS and measure the building with a total station.

If the building is in a mapped Special Flood Hazard Area, the permitting agency will normally require certified elevations for the lowest floor, and an elevation certificate is the standard way to provide them. Outside mapped zones it is optional, but useful for insurance rating.
