A Lane County flood zone map check belongs in the due diligence for any Lane County property, from a house lot in Eugene to farm ground near Cottage Grove. Here's how to read FEMA's map for a Lane County, OR property and match it to the parcel record.
We'll cover finding a Lane County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
How to check the Lane County flood zone map
The authoritative source for a Lane County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. Download the FIRM panel FEMA lists as effective for that part of Lane County. If the PDF panel for Lane County is hard to read, the National Flood Hazard Layer viewer is easier to use, which displays how much of a Lane County parcel sits inside the zone. Switch to the ORMAP statewide tax lot viewer and track down the same tract close to Creswell. The Lane County record gives the parcel ID and legal description that an insurer or lender near Eugene may ask for.
Finding the tract on the Lane County map
Lane County parcels are viewed through a statewide map, the ORMAP statewide tax lot viewer; zoom toward Junction City to reach them. ORMAP gives the map and tax lot number for a county property near Eugene; the account details come from the county. For a backup route to the map covering Eugene, our Lane County directory entry keeps the link current.
High, moderate and minimal risk in Lane County
Any Lane County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Eugene uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. If a Lane County parcel displays shaded Zone X, it falls between the base flood and the 500-year flood. Unshaded X (or C) on the Lane County panel means minimal risk.
Low ground and small streams around Eugene
Small streams and ditches near Eugene may not be studied in detail can still flood; FEMA says moderate- and low-risk areas still carry risk.
Where Lane County land records are kept
Deeds and plats behind the Lane County map are kept by the county's recording office; the official Lane County website names which office that is. A deed book and page or instrument number on the county record is the fastest way to pull the document for a lot in Creswell.
Near the Lane County line
A farm near the county line can carry separate records in Benton County, Deschutes County, and Douglas County as well. Every map bordering Lane County is listed on our Oregon directory.
Lane County at a glance

Unincorporated communities in Lane County, including Cheshire, Dexter, and Elmira, show up as small groups of parcels along the roads. Census Bureau estimates put Lane County at about 381,181 residents in 2023 on roughly 4,554 square miles of land.

Flood insurance and building rules in Lane County
Here's why the zone matters at a closing in Eugene. When a Lane County home sits in a Special Flood Hazard Area and secures a loan from a federally regulated or insured lender, flood insurance is mandatory, as long as Lane County or the town participates in the NFIP. In Zone X near Eugene, insurance is a choice, not a mandate, although a lender in Oregon can still ask for it. If a building near Creswell sits above the flood line, FEMA's LOMA process allows a review, typically backed by an elevation certificate from a surveyor who works in the county. Building or filling inside a mapped zone near Eugene often requires a permit and an elevation check, so call the county or the town office in Eugene before work starts.
Lane County, OR: common questions
How can I check a Lane County, OR flood zone?
Look it up at FEMA's Flood Map Service Center, then match the parcel lines in the ORMAP statewide tax lot viewer; for land near Coburg, a zone starting with A or V is high risk.
What is a base flood elevation for a Lane County property?
Near Coburg, the base flood elevation marks how high the 100-year flood is expected to rise, and a surveyor compares the building near Florence to it.
My lot in Florence displays Zone AE. What does that mean?
Yes, a tract close to Coburg in Zone AE is high risk: a 1-percent-annual-chance floodplain where FEMA lists a base flood elevation.
Does a 100-year floodplain near Coburg flood only once a century?
No, ground around Florence mapped that way faces a 1-percent annual chance, and two floods in one decade near Florence are possible.
Can I see flood zones on the Lane County GIS map?
Check the layer list in the ORMAP statewide tax lot viewer; if Lane County includes a floodplain layer, confirm the zone on FEMA's map anyway.
