Fundamentals Of Site Grading Plan

By | September 10, 2021

Site Grading Plans show the details that will be on the surface following installation. A representation of the ground's appearance after construction is usually created by a civil engineer.

Site grading plans will use the final grades from all areas that were affected and those that were not. The engineer will use a site grader plan to show how a plan layout may look on a 2-dimensional plane. You can get the precise grading design from

The quality of the site grading plans is a key factor in Land Development. As time has passed, both land development approvals and zoning approvals have improved.

Site Grading Plan documents are multi-sheet plans, which often include a Drainage plan and grading plan. If the project is sufficiently large, these two sub-disciplines may be separated into separate sheets. Each sheet will contain a separate but connected Grading Plan and Drainage Plan.

Drainage plans and separate grades will often include details such as rim/grate and invert elevations (bottom pipes) that are associated with inlets (catch bows), storm manholes, and flared outlet structures.

The estimated cut and fill quantities must be shown by the engineer who created the grading plan. These measurements are used as a guideline by the earthworks contractor to calculate the soil movement during grading.

If your home is built on floodplains, building inspectors will be particularly attentive to the floor elevation. This information is usually included in the on-site grade plans.
