Ahead of any purchase around Gridley, check the Paradise flood zone map: FEMA's zone label affects insurance, permits and resale. Covered here for Paradise: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Getting started with the Paradise flood zone map
Start with FEMA's Flood Map Service Center: search an address around Oroville, and choose the dynamic map. A tract near Chico without an address can still be found: pan from the closest town then click the parcel area.
Opening the official parcel viewer
Parcels around Gridley appear on the Butte County parcel viewer, which opens without registering. Out toward Oroville, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Oroville, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
A word on accuracy
The acreage figure is a tax-roll number; only a licensed surveyor establishes the real corners on land around Gridley. On ground around Oroville, records update in batches, so a deed recorded last month might lag behind.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Oroville, so load it before you lose signal. A saved image of the lot near Gridley and its lines is a good backup.
City limits and county records
Paradise sits in Butte County, California, which means parcel data comes from the county. For acreage around Biggs, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits near Oroville often follows county rules instead.
What to request from a seller
Request whether the home has flooded for the house near Oroville; an insurance quote early keeps the budget honest.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; surveyors near Biggs use that number. In and around Oroville, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Butte County parcel viewer to confirm you have the right parcel near Oroville.
Beyond the mapped zones
Low-lying fields near Gridley aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Oroville can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Butte County in a few facts
Oroville holds the county offices, home to the main records offices. Other places on the map include Chico, Biggs, and Gridley, where town lots give way to larger tracts. About 207,172 people live in Butte County (Census Bureau estimate, 2023) spread over about 1,636 square miles. Places such as Butte Sink National Wildlife Refuge help you orient on the aerial around Biggs.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Biggs are kept by the County Recorder. If the land is near Oroville, have ready the book and page shown in the record panel so staff can find the deed fast.
When a parcel crosses a boundary
Butte County meets Colusa County, Glenn County, Plumas County, Sutter County, and Tehama County, all with their own assessor records. Ground near Oroville that runs to the line may show up in two county records, so look at the neighboring map too. If you're looking near Gridley, our state page links each neighboring county map across California.
Insurance, lenders and building
For property near Chico, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Chico usually means extra permit review; ask the local floodplain administrator before you plan.
How land is described here
California is laid out under the Public Land Survey System, so rural legal descriptions near Biggs cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Biggs odd-sized. Copy the legal description from the record for the parcel near Gridley before you request a deed or survey.

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.
