Supplemental Information

The King County Agricultural Land Use and Infrastructure Assessment (“KC Land Use Assessment”) is intended to provide periodically updated data on the status of agricultural land use in King County for decision makers, land owners, resource agencies, researchers and the general public.

King County collected agricultural land use data in 2001, 2003, 2006, 2013, and 2015 as well as 2017.

Although this assessment was conducted in 2017, aerial images from 2015 were referenced for many areas since that was the most recent available at the time.

Farmed Berry Cane Berry - Presence of managed cane berries (i.e., blackberries/raspberries) or trellising structures that indicate active management

Farmed Berry Strawberry - Presence of strawberries.

Farmed Commercial Cut Flower - Presence of annual or perennial flowers. Flowers interspersed with vegetables will be classified as “Farmed Vegetable”

Farmed Commercial Nursery - Presence of commercial plants to be sold for ornamental, landscape, or garden purposes. Because some nurseries often are all paved or are gravel, we did not always delineate “Farm Road” within a nursery.

Farmed Commercial Tree Farm - Presence of a tree farm (i.e., poplar plantation, Christmas trees). The notes field should include specifics about the tree operation

Farmed Commercial Turfgrass - Presence of sod far (includes fields with sod as well as exposed mineral soil from harvested portions of the farm).

Farmed Feed Corn - Stand-alone corn field use for grain and silage (corn plots interspersed with row-crop vegetables and apparently grown for human consumption is classified as “Farmed Vegetable Sweet Corn”.

Farmed Hay/Silage - Grassland or field where there are no signs of recent/ongoing livestock use but is being cut/managed for hay/silage (e.g., recent cutting/baling, tire rutting, manure spreading).

Farmed Livestock Cattle - Presence of cattle either dairy or meat. Often barbed fences
