Before an offer near Benicia, pull up the Dixon flood zone map: FEMA's zone label affects insurance, permits and resale. What this Dixon guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Solano County parcel viewer.
Where the Dixon flood zone map lives
The official source is FEMA's Flood Map Service Center: search an address around Rio Vista, and choose the dynamic map. Vacant ground around Vallejo is still easy to locate: search the nearest road then click the parcel area.
Where the parcel data lives
Lots and tracts near Suisun City are published on the Solano County parcel viewer, which opens without registering. On ground around Suisun City, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. Out toward Rio Vista, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Which office to call
Questions about value or the owner field for land near Vallejo go to the County Assessor, which maintains the tax roll. Zoning, permits and septic questions near Vacaville are for the local planning and health departments, town or county, depending on location.
When a parcel crosses a boundary
Solano County borders Contra Costa County, Marin County, Napa County, Sacramento County, and Sonoma County; every one of them runs a separate parcel map. Ground near Fairfield that runs to the line can be split across two assessors' files, so check the adjacent map too. For acreage around Vallejo, the Platbookmapper state page lists every neighboring county map for California.
Reading the legal description
California follows the Public Land Survey System, which means a tract near Fairfield is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Suisun City odd-sized. Copy the legal description from the record for the parcel near Benicia when you talk to a surveyor.
Where Dixon fits in
Dixon lies within Solano County, California, so its parcels are on the county's map. For land near Fairfield, City or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits near Suisun City generally follows county rules, not municipal ones.
Reading A, AE and X
Zone AE comes with a base flood elevation, while plain Zone A does not; surveyors near Suisun City use that number. If you're looking near Vacaville, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
A short flood checklist
Ask the seller for any Elevation Certificate for the house near Vacaville; an insurance quote early avoids surprises.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Benicia, though signal can drop in rural spots. A saved image of the lot near Fairfield and its lines keeps working without signal.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the Solano County parcel viewer next to confirm you have the right parcel near Vacaville.
Limits of the parcel data
The acreage figure is an assessed number; only a licensed surveyor establishes the real boundary for a parcel near Vacaville. Owner names and values update on a schedule, so a recent sale near Rio Vista can take weeks to appear.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Suisun City are filed with the County Recorder. For a parcel near Vallejo, have ready the document number listed on the parcel record to skip a name search.
Beyond the mapped zones
Small streams around Suisun City aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Vallejo can limit building too; check the National Wetlands Inventory mapper for a first look.
What a flood zone means for a buyer
For a parcel near Rio Vista, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Vacaville in a mapped zone usually means extra permit review; check with the county or town building office early.

What is a LOMA for land near Benicia?
