Farm size and land-use policy: An oregon case study

Farmland conversion has become an important public policy issue in the United States and in many other countries. An important part of policy considerations in farmland protection programs is the minimum parcel size for farm-related land divisions and dwelling units. The rationale for establishing size thresholds varies considerably among jurisdictions. This article reviews the policies and criteria used in the United States and several other countries, discusses the policy implications of different types of objectives, and presents the results of a case study in Oregon. The case study was the first attempt by an Oregon county to articulate a set of measurable criteria to quantify a definition of commercial agriculture for land-use applications. The criteria and data base used in the model provide a systematic procedure to process permit applications in an objective, consistent manner. The ordinance was adopted in February 1988 and has worked successfully since that time. The article summarizes permit activity under the new ordinance and comments on its effectiveness.
