Regional Policy Plan (RPP)

The Cape Cod Commission Act requires the preparation of a Regional Policy Plan (RPP) that presents "a coherent set of regional planning policies and objectives to guide development throughout said Barnstable County and to protect the region's resources." The plan, which is updated at least once every five years, must 

identify critical resources and management needs

state a growth policy for the region

present regional goals, and

present a policy for coordinating regional and local planning efforts

The Role of Technical Guidance in Regulatory Review 

Separate from, but in support of this RPP, the Commission has developed Technical Guidance. The Technical Guidance contains Placetype Maps, Technical Bulletins and references to resource areas mapped by federal, state and local governments. There is a Technical Bulletin for each of the fourteen goals of the RPP. The primary application of the Technical Guidance is during DRI or other regional regulatory review, and its primary purpose is to assist the Commission in its determination of whether a project is consistent with applicable RPP goals and objectives, and alternatively, to detail how an applicant could design and pursue its project to meet the applicable RPP goals and objectives.
