Park Planning, Design & Construction Terms

Park Planning terms

Building Codes – Local requirements for how building shall be constructed.

 

Building Permits – Permits required for buildings and structures through the review of plan documents by local authority prior to construction.

 

Comprehensive Master Plan – A general plan, master plan, or land use plan — is a document designed to guide the future actions of a community with particular regard for land use. 

 

Concept Plan - Concept plans are part of the initial planning and budgeting phase of a development project. Concept plans can include a land development feasibility analysis and assess a potential site for development.

 

Contour - The difference in elevation or vertical distance measured between consecutive contour lines that represent a consistent elevation along each line. 

 

Connectivity – The ability to make and maintain a connection between two or more points especially accessing parks using trails, sidewalks and pedestrian and bicycle facilities.
