A site plan shows proposed or existing improvements in relation to a property, such as buildings, access, grading, utilities, and drainage.
Definition
A site plan presents selected existing or proposed improvements and their relationship to a property. Depending on project and review requirements, it may show buildings, circulation, parking, grading, utilities, drainage, landscaping, or property constraints. Civil engineering firms often coordinate information from several disciplines, but the scope should identify the design stage, base mapping, details, and revisions included. Required content and scale vary by project and reviewing authority. A site plan supports coordination and review; it does not replace detailed engineering plans, permits, construction documents, or a boundary survey. It also does not establish that every depicted feature has been approved or constructed. Owners use the plan to understand how proposed work fits the site and to identify interfaces that may affect scope, schedule, and approvals. See ASCE for civil engineering resources.
How owners use it
- An owner reviews a site plan to understand how proposed improvements fit within property and access constraints.
- A project manager uses the plan to coordinate grading, drainage, utilities, and building interfaces.
- A firm states the design stage, discipline inputs, review cycles, and level of detail included in its site plan scope.
