Weighing a property around Exeter? A quick look at the Porterville flood zone map shows whether FEMA puts it in a high-risk zone, and it costs nothing to check. Covered here for Porterville: locating a parcel on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
Where the Porterville flood zone map lives
Flood zones come from FEMA's Flood Map Service Center: search an address around Tulare, then open the map view for that panel. A tract near Tulare without an address can still be found: zoom in from the nearest road then click the parcel area.
Where the parcel data lives
Your first stop is the Tulare County parcel viewer; it includes each assessed parcel around Visalia and Dinuba. For a home near Tulare, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Farmersville, write down the parcel ID from that panel; each office in the county uses it to find the file.
Offices that can help
Recorded documents for a parcel near Farmersville are with the County Recorder, often with an online index. Zoning, permits and septic questions near Visalia need the planning or permitting office, depending on whether the land is inside town limits.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, plats and easements for land near Tulare sit with the County Recorder. With a lot near Visalia, use the book and page from the tax record so staff can find the deed fast.
Tulare County in a few facts
Visalia is the county seat, home to the main records offices. Smaller places on the map include Lindsay, Exeter, Farmersville, and Tulare, where town lots give way to larger tracts. Around 479,468 people live in Tulare County (Census Bureau estimate, 2023) across roughly 4,824 square miles. Landmarks such as Kaweah Oaks Preserve are easy to spot when you zoom out from Farmersville.
Porterville, CA: the basics
Porterville sits in Tulare County, California, and the county assessor maps its lots. On ground around Visalia, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits near Farmersville usually answers to county rules, not municipal ones.
Decoding the flood zone labels
For acreage around Exeter, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a tract near Lindsay, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
When a parcel crosses a boundary
Tulare County meets Fresno County, Inyo County, Kern County, and Kings County; every one of them runs a separate parcel map. Acreage along the edge near Tulare may be split across two assessors' files, so look at the adjacent map as well. Closer to Dinuba, our state page lists every bordering county map across California.
A short flood checklist
Request for any Elevation Certificate for the house near Tulare; getting a quote early keeps the budget honest.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Tulare County parcel viewer to see exactly which lot near Exeter you're looking at.
Lenders and permits
For a parcel near Exeter, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Farmersville usually means extra permit review; call the permitting office before you plan.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so a fence near Farmersville may sit several feet off the line on screen. Closer to Tulare, records update in batches, so a deed recorded last month can take weeks to appear.
Legal descriptions in California
California uses the Public Land Survey System, which means a tract near Farmersville is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Lindsay vary in size. Write down the legal description for the tract near Dinuba for any title or survey request.
Water near Dinuba
Creeks and ditches near Dinuba aren't always studied in detail, so walk the land after rain. Marshy spots near Exeter can limit building too; check the National Wetlands Inventory mapper for a first look.

What is a LOMA in Porterville?

What's the tax parcel number used for near Visalia?

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.
