Elevation Certificates in Vallejo: Local Conditions

Vallejo's flood picture has a bay side and a creek side. According to FEMA's Solano County Flood Insurance Study, a levee system built by local interests along the east side of the Napa River and Mare Island Strait protects the city from high tides, and most of Vallejo drains west into the strait and the river. Inland, the study divides the city into the Chabot, White Slough, Austin Creek, and Lemon Street drainage areas. In the lower Austin Creek, White Slough, and Chabot areas, occasional levee breaching causes shallow flooding. Runoff east of Interstate 80 is sent to a storm drain that outlets at the foot of Solano Avenue, and in high flows part of it overflows into Lake Dalwigk, a holding basin in the Lemon Street area.

Vallejo's maps have been revised more than most. The City's Engineering Division posts the documents for a map revision effective June 9, 2014 that restudied Rindler Creek and its tributaries, Miller Ditch, and the Lemon Street Canal, affecting Vallejo, Benicia, and unincorporated Solano County. That revision also covered South Fork Rindler Creek, Blue Rock Springs Creek, Lake Dalwigk, and the Magazine Street Canal. FEMA also issued Letters of Map Revision for a tributary to American Canyon Creek in 2009 and for North Fork Rindler Creek in 2013, and the bay shoreline was restudied in the San Francisco Bay coastal revision effective August 3, 2016. Because of all these changes, an elevation certificate or zone determination from before 2014 may describe a different map than the one your lender uses today. Vallejo is FEMA community 060374.

Our survey ties to NAVD88 benchmarks with GNSS and uses a Trimble S3 total station to measure the lowest adjacent grade, top of the lowest floor, garage slab, flood openings, and HVAC and utility equipment, with the photographs FEMA requires. We sign and deliver FEMA Form FF-206-FY-22-152 and identify the current FIRM panel and BFE for the building. If the ground at the structure is at or above the Base Flood Elevation, we can prepare a Letter of Map Amendment and file through eLOMA when the case qualifies.

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 Vallejo: FAQ

FEMA's June 9, 2014 revision restudied Rindler Creek and its tributaries, Miller Ditch, Blue Rock Springs Creek, Lake Dalwigk and the Lemon Street Canal, and the Magazine Street Canal. The City of Vallejo Engineering Division posts the study documents.

The certificate itself does not expire unless the building is changed in a way that affects the certified data. The map may have changed, though, so the zone and BFE on an older certificate may not match the current FIRM. In that case a new certificate referencing the current panel is often worth having.

FEMA's study says locally built levees along the Napa River and Mare Island Strait protect the city from high tides, but the flood zones on the FIRM are what lenders use. Check your parcel at msc.fema.gov and use an elevation certificate to document the building.
