The purpose of the Signing and Delineation Unit (SDU) Procedures Manual is to provide guidance to the designer, reviewer, project manager and implementer of Signing and Delineation projects. The intent is such that projects are planned, scoped, developed, reviewed, coordinated, documented and constructed the same way regardless of where or by whom the plans are developed. The ultimate goal is to sign and delineate a safe, consistent and reliable transportation network for all users.
