Construction Mitigation

A Construction Mitigation Plan (CMP) is a combination of diagrams, documents, drawings, and specifications that clearly define the steps that will be taken to demonstrate how the impacts to the community will be minimized, and how the impacts associated with any construction project will be managed.

The CMP was established to provide a consistent policy under which certain physical aspects of construction management will be implemented. The elements contained in the manual, see below, are related to the development process. It is intended that they apply to both public and private work designated herein.
