Land Development Handbook: Planning, Engineering, and Surveying, Third Edition

Predominantly an engineering effort, the final design phase is where fine-tuning and detailing of all site components occurs. Each infrastructure system roads, grading and drainage, utilities (gravity, pressure, and dry), vegetative or natural open space must be accounted for, coordinated, and designed with respect to the requirements of the specific review agency Sufficient information in the form of drawings, computations, details, narratives, and/or specifications must be provided such that regulatory agencies can review and approve final construction documents and contractors can implement the intended design.
Plans developed during this phase of the design are used for permitting, construction, and final cost estimating purposes; thus, it is important to maintain close and constant communication with other design team members architects; mechanical, electrical, plumbing engineers (MEPs); landscape architects; and private utility contractors, to name a few in order to accurately and efficiently coordinate plan interfaces. Such interfaces occur between the building and the site systems as well as between private property and public rights-of-way (ROW). The site-civil engineer is the intermediary connecting the building to public property and, consequently, is responsible for ensuring design consensus at these transition points. Key design elements such as location, size, invert, material preference,...
