Finding a lot on the Happy Valley GIS map
Parcel maps here are usually run by the county, not the town, so for Happy Valley the go-to is the ORMAP statewide tax lot viewer.
Getting to the right map
Your first stop is the ORMAP statewide tax lot viewer; it covers every tax parcel around Oregon City and West Linn. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, whether the land is near Damascus or elsewhere in the county. For acreage around Gladstone, write down the parcel ID from that panel; each office in the county uses it to find the file.
Where Happy Valley fits in
Happy Valley sits in Clackamas County, Oregon, which means parcel data comes from the county. Near Johnson City, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the city limits out by Damascus often follows county rules, not municipal ones.
Search tips
Acreage around West Linn might not have a street number, so zoom in from the nearest road and click the outline. In and around Damascus, searching by parcel number never misses, and you'll find it on tax statements.
When a parcel crosses a boundary
Clackamas County borders Hood River County, Marion County, Multnomah County, Wasco County, and Washington County, and each of those keeps its own parcel map. A tract near the line by Milwaukie may show up in two county records, so check the neighboring map too. For a tract near Gladstone, the Platbookmapper state page lists every neighboring county map for Oregon.
