Headwaters of Popes Head Creek at Brecon Ridge Subdivision Stream Restoration Project

Project Number: SD-000031-220 (PH9271/PH9272)

Project Update: March 27, 2024

Design is currently on hold until easements are acquired.

Project Background

The Popes Head Creek Watershed Management Plan identifies this project for stream restoration and stabilization as PH9271 and PH9272. In September 2019, Stormwater Planning Division staff initiated the project design.

Project Description

Existing conditions.

The project will restore approximately 3,000 linear feet of Popes Head Creek, stabilize stormwater outfalls, and re-establish the stream valley floodplain connection and riparian corridor. Over this reach, the stream is severely eroded, down cut, incised and overly widened.

Without the restoration project, a great potential exists that stream bed and bank instability will continue eroding and damaging privately-owned and homeowners’ association-owned property while continuing to further impair water quality in Popes Head Creek.

The goal is to implement a sustainable project to protect property, health, and safety while improving water quality. This will be accomplished by restoring the stream’s dimension, pattern, and profile to a form appropriate for current and future watershed conditions. The project will also restore equilibrium to the channel and riparian corridor supporting effective conveyance of water and sediment without excessive channel erosion and migration. The design will enhance the natural habitat supporting improved biodiversity and restoring channel and floodplain ability to naturally process excess nutrients and sediment. Protecting and preserving existing trees to the greatest extent possible is always a priority. The work will repurpose, and use removed trees and existing streambed material within the project reach to the greatest extent possible.

The project is part of Fairfax County’s larger efforts to restore degraded streams while improving overall water quality in local waterways and the Chesapeake Bay.

The primary restoration objectives are:

  • Improve water quality by stabilizing the continuously eroding bed and banks
  • Return/improve floodplain connectivity supporting improved ecosystem processes
    • Reduce volume and force of water in the channel
    • Naturally process nutrients and sediment on the floodplain
    • Provide groundwater recharge for the local aquifer
  • Enhance riparian forest habitat by planting native trees, shrubs, and herbaceous plants
  •  Restore the ecological function of the stream and the riparian zone to process phosphorous, nitrogen, and sediment
  • Restore and enhance the aquatic and riparian habitats
  •  Coordinate closely with community stakeholders to support project goals and commitment to future efforts to help maintain success

Project Location

The project begins on the south side of Braddock Road approximately 725 linear feet east of the Bellmont Drive intersection extending approximately 3,000 linear feet south.

Project Phase

Design is at the concept (35-percent) phase.


A 65-percent design plan will be started after needed easements are acquired.

What To Expect

Advancing the project through an iterative design process will take approximately 12 to 14 months. In addition to an initial introduction meeting, a meeting will be scheduled immediately prior to beginning construction. During the interim, ongoing low-impact site and ecological monitoring activities will continue.

Project Cost and Funding Source

Funding is approved for design. Construction funding is dependent upon future budget availability and allocations. Stormwater projects are funded through the county Stormwater Service District.
