Population and Land

The Methow Population and Land (PAL) Project is a sub-component of the State of the Methow Project. The PAL project is a series of reports and webpages that include information on the current conditions and trends in human population, land use, development, and land protection in the Methow Valley. The project is a “living” project, and data and associated reports will be updated annually. The project includes two written reports: (1) Human Population, Land Use, and Residential Development Report, and (2) Land Protection Report. The current versions of the reports provide data through July 2020. We recognize that 2020 and 2021 are times of significant change, due to COVID-19. We will update the reports after the July 2021 Okanogan County parcel data (from which much of the project’s data is based) becomes available.

The majority of private parcels are less than 5 acres in size.

Parcels by Size Class as Percent of Total Number of Private Land Parcels, 2020

While parcels over 40 acres in size represent only 5 percent of the total number of private parcels, when we look at total private land acreage, these larger size classes comprise almost half of the total acreage.

Development

About 52 percent of the private parcels in the watershed are developed.

Residential development status

The percent of private parcels that are developed is higher for the Upper and Middle Methow than the Lower Methow.

Private Parcel Development Status by Area

The number of developed residential parcels increased by 33 percent from 2005-2020.

Developed Residential Parcels

From 2005-2020, an average of 66 building permits for new residential structures were issued each year. Building was concentrated in the Upper Valley during this time period.

Land Protection

About 15 percent of private land acreage in the Methow Watershed has been protected (through conservation easements or purchase by non-profit conservation organizations), with percent protected being greatest for the Upper Methow.

Protected Acres of Private Land, 2020

18.5 percent of agricultural land has been protected (through conservation easements), as of November 2020. Percent of agricultural land protected is greatest for the Upper Methow, but acres protected is greatest for the Middle Methow.

Private Agricultural Land

Approximately 50 percent of the area within the 100-year floodplain in the watershed has been protected. “Protected” means that the land is within a conservation easement, owned by a conservation organization, or is held by public or tribal entities.
