What to check before hiring in Issaquah
- License: in Washington, as in every state, boundary, ALTA/NSPS and elevation work must be performed or supervised by a Professional Land Surveyor licensed by the state board. Ask for the license number and check it on the board's website.
- Records: a good surveyor starts with the deed, the recorded plat and the county records for your parcel. Having your deed or title commitment at hand speeds up the quote.
- Price drivers: lot size and shape, terrain and vegetation, how easy the original monuments are to find, and whether you need corners staked or a recorded plat.
- Flood insurance: if your property is in a FEMA flood zone, ask whether the surveyor also prepares Elevation Certificates.
