Title
Vacant and Developed Land 2021 [Oregon--Portland]
Description
Area appearing unimproved on 2021 aerial photography, without regard to developability and accessibility. On partially developed parcels, only undeveloped areas 1/2 acre or larger are included. Metro's Vacant Land Definition: Every tax lot is determined to be vacant, partially vacant, or developed. Vacant tax lots are those that have no building, improvements or identifiable land use. Developed lots must have improvements and specific land uses. For example, a paved parking lot is developed but an unpaved lot where trucks are parked is vacant. Lots under site development are only considered developed if structure is evident. For example, earthwork and grading are considered vacant but buildings under construction (foundation or more) are considered developed. If a developed tax lot has 1/2 acre (20,000-sq. ft.) or greater portion that is vacant, the lot is considered to be partially vacant and partially developed. A polygon is delineated around the occupied portion, which includes buildings, landscaped yards, etc. The remaining portion (greater than 1/2 acre) is coded vacant (vac = 1). Parks and open spaces are treated as developed. During the assessment of each tax lot, no consideration is given to constrained land, suitability for building, or to redevelopment potential.
