Before you buy or build near Roslyn, pull up the Ellensburg flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for Ellensburg: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Kittitas County ArcGIS parcel map.
Getting started with the Ellensburg flood zone map
The official source is FEMA's Flood Map Service Center: type an address near Roslyn, and pick the FIRMette or map view. Rural land near South Cle Elum with no street number is still easy to locate: pan from the closest town and click the spot.
Pulling up a parcel
Your first stop is the Kittitas County ArcGIS parcel map; it maps each assessed parcel around Roslyn and Kittitas. With a lot near Cle Elum, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Cle Elum, the parcel card normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Cle Elum, so load it before you lose signal. A saved image of the lot near Cle Elum and its lines is a good backup.
Land on the county line
Kittitas County touches Chelan County, Douglas County, Grant County, King County, and Pierce County, all with their own assessor records. Ground near Roslyn that runs to the line can show up in two county records, so look at the neighboring map as well. For a home near Kittitas, the Platbookmapper state page lists each bordering county map across Washington.
Ellensburg, WA: the basics
Ellensburg sits in Kittitas County, Washington, so its parcels are on the county's map. Ellensburg is also the county seat, so deeds and plats are filed in town. For acreage around Cle Elum, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the city limits near Roslyn usually falls under county rules instead.
What the map can't tell you
Listed acreage is an estimate; just a licensed surveyor establishes the real lines on land around South Cle Elum. For a home near South Cle Elum, records update in batches, so a deed recorded last month can take weeks to appear.
Beyond the mapped zones
Creeks and ditches near Cle Elum may not have detailed mapping, so walk the land after rain. Marshy spots near Cle Elum can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Questions to ask before you buy
Ask the seller whether the home has flooded on the property near Roslyn; getting a quote early avoids surprises.
Legal descriptions in Washington
Washington follows the Public Land Survey System, so deeds around Kittitas reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near South Cle Elum can be irregular. Keep the legal description for land near Cle Elum when you talk to a surveyor.
Zones on the Ellensburg flood zone map
Out toward Kittitas, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. Around South Cle Elum, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Deeds, plats and who keeps them
For anything that matters, get the recorded deed from the County Auditor; the parcel map near Kittitas only summarizes it. Inherited tracts around South Cle Elum may trace back through many deeds, and a title company earns its fee if money is changing hands.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the Kittitas County ArcGIS parcel map too to see exactly which lot near Kittitas you're looking at.
Insurance, lenders and building
In and around Cle Elum, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near South Cle Elum in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
Offices that can help
Questions about value or the owner field for land near Kittitas go to the County Assessor, the office behind the parcel record. Questions about what you can build around Roslyn go to planning, building or health offices, depending on whether the land is inside town limits.
