Weighing a property around Creswell? The Cottage Grove flood zone map tells you whether FEMA puts it in a high-risk zone, and the lookup is free. In this Cottage Grove guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the ORMAP statewide tax lot viewer.
The Cottage Grove flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: search an address around Lowell, then open the map view for that panel. A tract near Lowell without an address is still easy to locate: pan from the closest town and click the spot.
The free map to start with
Begin with the ORMAP statewide tax lot viewer; it maps each tax parcel from Creswell to Lowell. In and around Dunes City, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Coburg, the record panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Getting your bearings
Eugene holds the county offices, which is where the courthouse records live. Smaller places on the map include Creswell, Lowell, and Springfield, where town lots give way to larger tracts. Around 381,181 people call Lane County home (Census estimate, 2023) spread over roughly 4,554 square miles. Lane County dates to 1851, and some chains of title near Dunes City are long. Places such as Umpqua National Forest make handy reference points on the map near Lowell.
Cottage Grove, OR: the basics
Cottage Grove lies within Lane County, Oregon, and the county assessor maps its lots. Out toward Eugene, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the town limits out by Dunes City usually answers to county rules instead.
How land is described here
Oregon is laid out under the Public Land Survey System, so deeds around Creswell reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Dunes City can be irregular. Copy the legal description from the record for the parcel near Dunes City for any title or survey request.
Next door to Lane County
Lane County borders Benton County, Deschutes County, Douglas County, Klamath County, and Lincoln County, all with their own assessor records. Acreage along the edge near Creswell may be split across two assessors' files, so look at the neighboring map too. If you're looking near Lowell, our state page lists every bordering county map across Oregon.
What the map can't tell you
Acreage on the record is an estimate; just a licensed surveyor can set the real corners on land around Dunes City. For acreage around Dunes City, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Reading A, AE and X
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; surveyors near Dunes City use that number. For a home near Lowell, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Which office to call
Questions about value or the owner field for land near Coburg belong with the County Assessor, the office behind the parcel record. Building or septic questions for a lot near Dunes City are for the local planning and health departments, and the answer depends on jurisdiction.
Water near Creswell
Small streams around Lowell aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Coburg can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the ORMAP statewide tax lot viewer too to see exactly which lot near Dunes City you're looking at.
Lenders and permits
For a structure inside an A or V zone and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, and that holds around Coburg too. New construction in a floodplain near Coburg often needs a floodplain permit; ask the local floodplain administrator early.
Questions to ask before you buy
Ask the listing agent whether the home has flooded on the property near Eugene; an insurance quote early keeps the budget honest.

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.
