Before you buy or build near Clear Lake Shores, pull up the Dickinson flood zone map: FEMA's zone label affects insurance, permits and resale. What this Dickinson guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Galveston County ArcGIS parcel map.
Checking the Dickinson flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: type an address near Kemah, then open the map view for that panel. Vacant ground around Santa Fe is still easy to locate: zoom in from the nearest road and click the spot.
The free map to start with
Your first stop is the Galveston County ArcGIS parcel map; it includes each tax parcel in the county, Kemah included. If you're looking near Santa Fe, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a parcel near Clear Lake Shores, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
A short flood checklist
Ask the seller about past flood claims for the house near Kemah; an insurance quote early avoids surprises.
How land is described here
Older tracts around La Marque commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Santa Fe usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Friendswood for any title or survey request.
Dickinson and the county around it
Dickinson is part of Galveston County, Texas, which means parcel data comes from the county. If you're looking near League City, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Friendswood often follows county rules rather than the town's.
Zones on the Dickinson flood zone map
If you're looking near Kemah, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For property near League City, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Galveston County ArcGIS parcel map too to confirm you have the right parcel near Kemah.
What the map can't tell you
Listed acreage is an assessed number; only a licensed surveyor can set the real boundary on land around Friendswood. For acreage around Friendswood, records update in batches, so a deed recorded last month can take weeks to appear.
The paper trail behind a parcel
For anything that matters, pull the recorded deed through the County Clerk; the parcel map near La Marque only summarizes it. For a parcel near League City, have ready the document number from the tax record and the lookup takes minutes.
Places you'll see on the map
Galveston holds the county offices, home to the main records offices. Smaller places on the map include League City, Santa Fe, Kemah, and Clear Lake Shores, where town lots give way to larger tracts. Roughly 361,744 people live in Galveston County (Census Bureau estimate, 2023) on about 379 square miles. Galveston County was organized in 1838, and some chains of title near La Marque are long. Features like Clear Lake make handy reference points on the map near Friendswood.
Low spots and local drainage
Creeks and ditches near Friendswood aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Friendswood can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Land on the county line
Galveston County meets Brazoria County, Chambers County, and Harris County, all with their own assessor records. Acreage along the edge near La Marque can show up across two assessors' files, so check the neighboring map as well.

Insurance, lenders and building
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, and that holds around Santa Fe too. Remodeling a house in a zone near Clear Lake Shores usually means extra permit review; ask the local floodplain administrator early.
