Subdivision Grading Plan (SDGP)

A subdivision grading plan is required for each individual lot that is part of a new residential subdivision with an active, approved subdivision plan under bond. Each lot grading plan depicts final lot grading and proposed improvements including the size, location, and configuration of all structures.

Depending on the scope of your project, you may need to apply for a separate building permit record in PLUS. To determine whether your project requires a permit, visit When a Permit is Required. Once you determine the appropriate record type, review the associated Permit Library guide to find details regarding the submission and review process.


This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.



Homeowners or their duly authorized agents may submit subdivision grading plans, however, the plan itself must be certified by a professional engineer, land surveyor, architect or landscape architect licensed by the Commonwealth of Virginia and meeting the respective code requirements.



Before submitting, ensure you are aware of all applicable regulations and conditions that could affect your project to avoid surprises during the review process. Some of those factors include:

  • Zoning Information
  • Design Codes and Standards
  • Do I Need to Hire a Design Professional?
  • Floodplains
  • Resource Protection Areas (RPA)
  • Grading/Site Plans
  • Parking Tabulation
  • Types of Soils and Problem Soils
  • Researching Site Conditions

To get a detailed description about each regulation and condition, visit our Plan Ahead page.

Site Inspections

Before beginning any land disturbing activities associated with your approved site/grading plan and land disturbance permit, you are required to request a pre-construction meeting. Before requesting your pre-construction meeting, certain items must be completed such as an approved Virginia 811 ticket. To review all required items, visit the Site Inspection web page.


Conservation/Bond Release

The release of the associated conservation deposit is coordinated with your site inspector upon project completion. The assigned site inspector will notify Bonds and Addressing staff to initiate the conservation escrow release process. Any associated building permit records must have a passed final inspection.
