Site Plans

Civil engineering plans showing proposed improvements and their relationship to the property.

What this covers

Understanding Site Plans

Site design brings together the building layout, access, surface elevations, drainage and utilities. A current survey and a clear description of the proposed use provide the starting point for coordination.

When engineering may be required

When to involve an engineer

An engineer may be needed for site development, an expansion or changes that affect access, utilities or water flow across the property.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Engineering tasks

What the engineer may review

Topics that may be relevant to the review: ADA parking, French drain, asphalt, catch basin, clean room and culvert.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.
