Pulling up a parcel

Near San Juan Bautista, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it.

What the zone letters mean
With a lot near Bitterwater, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. Out toward Association of Monterey Bay Area Governments, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so pair it with the San Benito County ArcGIS parcel map to confirm you have the right parcel near Association of Monterey Bay Area Governments.

How land is described here
California uses the Public Land Survey System, so rural legal descriptions near Dunneville cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near San Juan Bautista can be irregular. Keep the legal description for land near Bitterwater for any title or survey request.
Low spots and local drainage
Creeks and ditches near Dunneville aren't always studied in detail, so look for water marks and debris lines. Wet ground around San Juan Bautista is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Association of Monterey Bay Area Governments often sits some distance off the line on screen. For a parcel near Dunneville, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Questions to ask before you buy
Near Association of Monterey Bay Area Governments, ask the seller whether the home has flooded before closing; an insurance quote early keeps the budget honest.
Lenders and permits
For a structure inside an A or V zone and the loan is federally backed or regulated, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, which applies near Aromas as much as anywhere. New construction in a floodplain near Association of Monterey Bay Area Governments can trigger elevation rules; ask the local floodplain administrator early.
Deeds, plats and who keeps them
With a lot near Hollister, the map is an index, not the title: deeds, plats and easements for parcels in the county are filed with the County Recorder. Long-held tracts near San Juan Bautista can sit on a long string of deeds, so a title company can sort it out on a real sale.
Who handles what
For assessment questions about property around Ridgemark belong with the County Assessor, since that office keeps the assessment data. Questions about what you can build around Association of Monterey Bay Area Governments are for the local planning and health departments, town or county, depending on location.
Frequently asked
Do I need to worry about flooding in Zone X for land near Bitterwater?
X zones around Aromas are lower risk, not no risk, and floods still happen outside high-risk zones.
Does the county parcel map show flood zones for land near Association of Monterey Bay Area Governments?
A flood layer may appear in the San Benito County ArcGIS parcel map layer list; confirm a lot near San Benito River on FEMA's map either way.
What does an AE label mean for a lot near San Juan Bautista?
Short answer: AE is a Special Flood Hazard Area with a published base flood elevation, so builders near Hollister design to that elevation.
What is a LOMA around San Juan Bautista?
It depends, but FEMA's LOMA process is the usual route when a building near Tres Pinos sits above the base flood elevation; a surveyor's elevation data supports it.
Can I settle a boundary dispute with the map near Pajaro River?
For land near Ridgemark, parcel lines are tax drawings, not surveys; a survey sets the real corners

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.
