Ahead of any purchase around Mount Hood, look at the Hood River County flood zone map: a mapped flood zone changes insurance, permits and resale. This Hood River County guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the ORMAP statewide tax lot viewer.
The Hood River County flood zone map: start here
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near Cascade Locks or elsewhere in the county. Vacant ground around Columbia River Gorge can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Begin with the ORMAP statewide tax lot viewer; it includes each tax parcel around Cascade Locks and Lenz. If the land is near Dee, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Mount Hood Wilderness, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Decoding the flood zone labels
On ground around Badger Creek Wilderness, A and V zones are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. Near Columbia River Gorge, a low-risk label isn't a guarantee: according to FEMA, floods happen outside mapped zones too.
Getting answers from the right desk
If the acreage or value on a parcel near Mount Hood Wilderness looks off are handled by the County Assessor, since that office keeps the assessment data. Questions about what you can build around Cascade Locks go to planning, building or health offices, and the answer depends on jurisdiction.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the ORMAP statewide tax lot viewer next to confirm you have the right parcel near Parkdale.
Questions to ask before you buy
For a tract near Mount Hood Wilderness, request whether the home has flooded before closing; getting a quote early keeps the budget honest.
Beyond the mapped zones
Small streams around Columbia River Gorge may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Parkdale can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
A quick look at the area
Hood River serves as the county seat, where most land records are kept. Other places on the map include Cascade Locks, Mount Hood, Odell, and Parkdale. Roughly 23,745 people live in Hood River County (Census estimate, 2023) across roughly 522 square miles. Hood River County was organized in 1908, which matters when you trace an old farm's title. Features like Columbia River Gorge and Badger Creek Wilderness help you orient on the aerial.
Legal descriptions in Oregon
Oregon follows the Public Land Survey System, so deeds around Lenz reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Dee can be irregular. Keep the legal description for land near Dee for any title or survey request.
Insurance, lenders and building
In and around Badger Creek Wilderness, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Parkdale in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Mount Hood Wilderness, though signal can drop in rural spots. A saved image of the lot near Lenz and its lines helps when you meet an owner or agent.
Limits of the parcel data
Listed acreage is an estimate; only a licensed surveyor can set the real lines on land around Mount Hood. If the land is near Dee, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Recorded documents worth pulling
For a tract near Dee, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county sit with the County Clerk. Out toward Columbia River Gorge, bring the document number listed on the parcel record so staff can find the deed fast.

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.
