Weighing a property around Granger? The Grandview flood zone map tells you whether the lot falls inside a mapped floodplain, and the lookup is free. In this Grandview guide: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Checking the Grandview flood zone map step by step
Start with FEMA's Flood Map Service Center: search an address around Granger, then open the map view for that panel. Vacant ground around Granger can still be found: zoom in from Interstate 82 and click inside the land.
The viewer Yakima County publishes
Your first stop is the Yakima County parcel viewer; it includes every assessed parcel from Mabton to Selah. For acreage around Granger, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a home near Sunnyside, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
A quick look at the area
Yakima serves as the county seat, which is where the courthouse records live. You'll also find Mabton, Sunnyside, Granger, and Moxee. Roughly 256,643 people live in Yakima County (Census estimate, 2023) on some 4,295 square miles. Yakima County dates to 1865, and some chains of title near Granger are long. Features like Wenatchee National Forest help you orient on the aerial around Moxee.
Questions to ask before you buy
Ask the seller whether the home has flooded for the house near Granger; an insurance quote early avoids surprises.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Selah are kept by the County Auditor. Inherited tracts near Sunnyside may go back through several deeds, so a title company can sort it out on a real sale.
Water near Granger
Creeks and ditches near Selah aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Mabton is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Grandview, WA: the basics
Grandview sits in Yakima County, Washington, so its parcels are on the county's map. For property near Selah, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the town limits near Granger often follows county rules, not municipal ones.
Field tips
Most viewers work in a phone browser, useful out on a road near Mabton, but coverage can be spotty out of town. A printout of the tract near Sunnyside is a good backup.
When a parcel crosses a boundary
Yakima County touches Benton County, Grant County, King County, Kittitas County, and Klickitat County, all with their own assessor records. Acreage along the edge near Sunnyside can be split across two assessors' files, so check the adjacent map as well. Near Sunnyside, our state page lists each bordering county map for Washington.
Reading A, AE and X
If you're looking near Granger, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. Around Sunnyside, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Yakima County parcel viewer too for the outline of the tract near Granger.
Which office to call
Deeds, mortgages and recorded plats for land near Sunnyside are with the County Auditor, usually searchable by name or document number. Questions about what you can build around Sunnyside are for the local planning and health departments, town or county, depending on location.
Limits of the parcel data
Listed acreage is an assessed number; just a licensed surveyor sets the real lines on land around Moxee. For property near Moxee, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Lenders and permits
If the land is near Mabton, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Mabton in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
