The objective of this study was to present criteria and procedures for evaluation of Joint Development (JD) above, below, or beside state highways. Application of the procedures are illustrated over a wide range of joint development situations, both (1) for establishing state or local JD policy, and (2) for making decisions about JD projects in a more timely and comprehensive manner, and in a way that will contribute toward improving the quality or urban life or the enhancement of rural environments. The approach taken in the Guidelines is sequential, systematic, and interdisciplinary; that is, it uses a series of successively more detailed and comprehensive planning and evaluation procedures for JD decision making, relying on a wide range of specified physical, economic, social, and legal criteria. In use, the Guidelines envision a three-stage planning and evaluation process: (1) identification of the need or potential for JD projects; (2) comparison of project proposals against policies, criteria, and standards designed to avoid or minimize negative impacts and increase favorable impacts; and (3) refined definition of costs and benefits when warranted.
This supplement to the Guidelines report (described above) presents the results of analyzing seven actual JD proposals, located along Interstate 5 in the State of Washington, according to the procedures suggested in the Guidelines.
