Founded in 1999, ALS is a local, family-run business, offering consulting services in land surveying, land development, and planning throughout the Puget Sound Region. While we have many of the same resources as larger corporations, our focus is still on paying the same attention to clients as a smaller operation. Backed by 20+ years of experience, our team follows through from beginning to end to provide clients with quality product in a timely manner.

Definition of the exterior boundaries and corners of a parcel and indication of easements / encroachments often to show limitations imposed by state or local regulations.

Includes short plats, formal plats, and binding site plans. Involves dividing parcels of land into smaller tracts, lots, or estates to sell them or reduce taxation.

Involves the process of interpreting construction plans and marking the location of proposed new structures such as roads or buildings.

how it works

01 finalizing a project scope

We receive authorization by the client to perform a survey by means of either a verbal commitment or signed contract. At this point, an estimate is given, and half of the total is paid by way of sent invoice. A timeline is given for completion. The client provides any available property information to the surveyor. At which point, the surveyor performs the research needed to make the necessary calculations before heading out into the field.

02 fieldwork

The survey field crew goes to the property and measures any permanent, non-movable structures and improvements. The crew searches for subdivision survey monuments (iron pipes, rebar, cotton spindles, railroad ties, crosses, etc.). Fieldwork relating to specific survey types is done.

03 officework

The information collected in the field is taken to a mapping software (AutoCAD) to create a "drawing" of the property. Information is used from the subdivision plat and title work to establish lot dimensions, building lines, and easements. At which point, the facets of the project are reviewed by our licensed land surveyor.

04 completion + payment

The final copies are delivered to the client and/or title company along with the other half of the invoice. If a title company is involved, costs for the survey can typically be included in the buyers' closing costs. Completed maps are recorded to local municipalities if requested.

our regulars

“I build in the north Seattle area and have used Jouni for probably the last 7 or 8 years. I build mostly single-family homes. Jouni has always had good prices and has done an excellent job for me. My favorite quality of Jouni’s is that if you need a job done next Tuesday, you know he will be there.”

John Harrison

JSH Construction

“Jouni is the best guy I’ve found in years for certifying property lines! I’ve been working with ALS for over 5 years and have found my experiences to very easy to work with. He understands our needs and makes the time to finish projects on a prompt and timely schedule. It’s great to deal with the guy that’s doing the work with no middleman–things that are often found with larger operations.”

Ed Olson

Pacific Garages, LLC

“Having worked with Acreage Land Surveying for over 5 years, we appreciate Jouni’s attention to detail and quick turnaround, which are only some of the reasons we keep coming back! Being able to have one person for a contact that also handles all parts of the work to be done is a large part of why we like to work with a smaller company like ALS.”
