drainage basin app icon

A new interactive Geographic Information System (GIS) tool allows users to pick a point on a map and the tool will automatically delineate the basin draining to that point for any location in the county. Drainage basins, or watersheds, are areas of land that drain streams and rainfall to a common outlet.

This valuable data provides engineers quick estimates of the drainage areas to a given point and can be used by landowners to estimate drainage areas on and around their own property. County staff ecologists use this same data to evaluate the relationships between land use and hydrology, and their influence on stream condition, water quality and aquatic life.

To explore the drainage basin of your interest, check out the newest GIS app: Drainage Basin Delineation Tool, which uses LiDAR data (the most accurate elevation surface available), to delineate drainage basins. To learn more about watersheds, visit Watersheds | Public Works and Environmental Services.

This is only one of many GIS applications developed by Land Development Services (LDS). To explore more LDS GIS applications please visit our LDS Mapping Applications homepage.

Virginia Stormwater Management Plan (VSMP) Regulatory Update (9VAC25-880) - New Virginia Pollutant Discharge Elimination System (VPDES) Construction General Permit Registration Statement

Summary: The updated 2019 Registration Statement for General VPDES Permit Coverage for Discharges of Stormwater from Construction Activities (VAR10) reflects the November 25, 2020, final exempt regulatory update affecting requests for construction general permit coverage. Specifically, any permitted land-disturbing activity that will generate disposal of non-agricultural fill off-site is required to report each off-site area that will receive the fill as well as the contents of that excavated material. This disclosure is required whether the off-site disposal area will be covered under the requested permit or another VPDES permit. 

DEQ Logo

Effective Date: As required by the Department of Environmental Quality (DEQ), the new VPDES Registration Statement is effective January 1, 2021. Beginning, January 1, 2021, older versions of the 2019 Construction General Permit registration statement will no longer be accepted. 

Process: Per the updated regulatory language found under 9VAC25-880-50 B.5, the operator must submit a registration statement to the Fairfax VSMP authority that specifies whether excavated material (i.e., fill) will be transported off site for disposal; the name and physical location address, when available, of all off-site excavated material disposal areas, including city or county; latitude and longitude in decimal degrees (six digits – ten-thousandths place); and the contents of the excavated material.

As part of this regulatory update, DEQ is required to disclose to every locality where the fill will be disposed of, including the source of the fill and the contents of the fill. The Office of Stormwater Management with DEQ will add this information to the DEQ website. 

The 2019 Registration Statement form has been updated to reflect these changes. 

Registration Statements may continue to be submitted electronically using the following address: Please be sure to include all attachments and make sure the Registration Statement is completed and signed by the appropriate person, as explained in the instructions.

2021 Comprehensive Unit Price Schedule

Summary: Implementation of the 2021 Comprehensive Unit Price Schedule (UPS) 

Effective Date: The 2021 UPS will go into effect on March 1, 2021. This formulaic change reflects a 2.1% increase linked to inflation as published in the Engineering News Record 2021 Construction Cost Index (published in January 2021). Affected submittals include the following: 

  • New bond requests
  • Replacement bond requests
  • Bond extension requests
  • Bond reduction requests
  • New conservation deposit requests
  • Replacement conservation deposit requests
  • Future construction deposit requests

In the case of development agreement extension and replacement requests, if the estimated value using the 2021 UPS exceeds the existing posted amount, the county will require supplemental security before approval of the request. As noted above, all bond reductions must be calculated using the 2021 UPS.  

The 2021 UPS will be available on the county website at on February 1, 2021.  

If you have any questions, please contact Morgan Wolfe in the Bonds and Agreement Center at 703-324-1519, TTY 711

When a land development project is initiated in Fairfax County, improvements to the public infrastructure, such as streets, sidewalks, utilities and other bondable items may be required. Learn more about Bonds and Agreements.

Starting January 4, 2021, if you submit your truss shop drawing package after permit issuance, you must do so as a revision in ProjectDox1. Standard revision fees will apply. Learn more about how to submit a revision to an issued ePlan. Please name the revision workflow “Truss Submission.” To avoid the review fee,  you may submit the truss shop drawings with your construction plans during initial permit application.

The truss shop drawing package must be placed in the ProjectDox “Documents” folder and include the following to pass prescreen review:

  • Profile sheets for all truss types in a single PDF file with a valid electronic signature of the Virginia-licensed designer.
  • Truss layout plan.
  • A completed Fairfax County Truss Plan Cover Sheet.

1 For permit applications originally submitted as paper plans before March 25, 2020, please submit your truss shop drawing package here.

Land Development Services Streamlines Building Permit Process

Changes Launch Today Nov. 16, 2020


Description automatically generatedIn a change that will make it easier for customers to apply for building permits in Fairfax County, Land Development Services (LDS) has upgraded ProjectDox, its plan review system. With this upgrade, LDS has simplified the permit application and plan upload process so all building plans can be submitted through ProjectDox. The county’s review of plans for compliance with the building code is a critical step in the permit process for multiple permit types.

“We are proud to be able to offer residential and commercial builders and home improvement DIYers a streamlined, all electronic, building plan review process,” said William D. Hicks, P.E., Director of Land Development Services. “We understand getting a permit is not the fun part of improving our homes and commercial buildings, so staff are working hard every day to find ways to continuously improve the process,” said Hicks.

Information for Returning Users

Ten new permit types have been added to ProjectDox:

  • Commercial Electrical
  • Commercial Mechanical
  • Commercial Plumbing
  • Commercial Pool
  • Demolition
  • Interior Alterations Residential
  • New Townhouse
  • Residential Addition
  • Residential Pool
  • Retaining Wall

These additions do not eliminate the existing permit types already in ProjectDox:

  • New Commercial Buildings
  • Commercial Alterations
  • New Single-Family Dwellings

The permit types above apply only to building permits; there have not been any changes to the site permits in FIDO such as site plan permit or the infill lot grading plans permit.

To efficiently expand ProjectDox, LDS had to reduce the number of permit types in FIDO. Many previously used permit types, such as the deck permit, are no longer available in FIDO with the ProjectDox expansion.

Visit our Residential Permit Type Guide and our Commercial Permit Type Guide to determine which permit you will apply for under the new, upgraded system.

We understand all change – even positive change – can be a little frustrating at first. LDS staff are standing by to offer additional ePlans support:

The overall permit process has not changed. All permits start in FIDO. The following web pages have been updated to show the process for accessing ProjectDox to upload your plans:

In addition to the residential and commercial permit-type guides referenced above, returning users may also find the following charts helpful:
