Ahead of any purchase around Woodland, pull up the Davis flood zone map: a mapped flood zone changes insurance, permits and resale. What this Davis guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Yolo County ArcGIS parcel map.
Getting started with the Davis flood zone map
For a more interactive look, open the National Flood Hazard Layer viewer, which lets you click a spot and read its zone. Vacant ground around Woodland is still easy to locate: search the nearest road then click the parcel area.
Where the parcel data lives
Your first stop is the Yolo County ArcGIS parcel map; it includes each assessed parcel from West Sacramento to Woodland. Around Woodland, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near West Sacramento, the record panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Getting your bearings
Woodland serves as the county seat, which is where the courthouse records live. Other places on the map include West Sacramento and Winters, each with its own cluster of lots. Around 220,544 people live in Yolo County (Census estimate, 2023) on some 1,015 square miles.
Where Davis fits in
Davis sits in Yolo County, California, and the county assessor maps its lots. On ground around Woodland, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits near West Sacramento generally answers to county rules rather than the town's.
Next door to Yolo County
Yolo County touches Colusa County, Lake County, Napa County, Sacramento County, and Solano County; every one of them runs a separate parcel map. A tract near the line by Woodland may be split across two assessors' files, so open the neighboring map too. On ground around Winters, our state page lists every neighboring county map for California.
Offices that can help
Questions about value or the owner field for land near Woodland are handled by the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near West Sacramento need the planning or permitting office, depending on whether the land is inside town limits.
Water near Winters
Creeks and ditches near Winters may not have detailed mapping, so walk the land after rain. Wetlands near West Sacramento can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Zones on the Davis flood zone map
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; builders around West Sacramento design to it. Near Woodland, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Winters, though signal can drop in rural spots. A screenshot of the parcel near Woodland with its ID keeps working without signal.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the Yolo County ArcGIS parcel map next to confirm you have the right parcel near Winters.
What a flood zone means for a buyer
If you're looking near Woodland, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Woodland often needs a floodplain permit; ask the local floodplain administrator early.
What to request from a seller
Ask the seller whether the home has flooded on the property near Woodland; getting a quote early avoids surprises.
Legal descriptions in California
California follows the Public Land Survey System, so deeds around Winters reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Winters can be irregular. Write down the legal description for the tract near West Sacramento for any title or survey request.
Backing up the map with records
For anything that matters, get the recorded deed from the County Recorder; the parcel line is a drawing of it, whether the land is near Winters or elsewhere in the county. If the land is near Woodland, have ready the instrument number shown in the record panel to skip a name search.
Davis: common questions
Is there a flood layer on the parcel viewer near Winters?
It depends, but a flood layer may appear in the Yolo County ArcGIS parcel map layer list, but FEMA's own map is the official source.
Do I need to worry about flooding in Zone X for land near Winters?
Good question; X zones around West Sacramento are lower risk, not no risk; many owners near Winters buy coverage anyway.
How often are flood maps updated for land near Woodland?
Short answer: a new study can move a zone line near West Sacramento; your community is notified before changes take effect.
How do I check the flood zone for an address in Davis?
Search the address near West Sacramento on FEMA's Flood Map Service Center; no account is needed.
Can I download parcel lines near Woodland?
Most viewers have a print or export tool, and it's worth keeping the parcel ID visible for land near Winters.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
