Public Works and Environmental Services Alert:
A new task order was authorized on July 10, 2024, with Wetland Studies and Solutions, Inc. for assessment, design and permitting of the stream restoration project. The field work for survey and geomorphological assessment began in September, 2024. Concept design delivery and a community design review meeting will be scheduled in September, 2025.
The proposed stream restoration project is identified in the Little Hunting Creek Watershed Management Plan as LH9249 and LH9229. The existing conditions of the channels within the project area exhibit the typical degraded form resulting from channel evolution in response to many decades of development and the increase of impervious surfaces within the watershed: an overly down cut and widening channel, floodplain disconnection, tree loss, property loss, unbalanced sediment transport, accelerated channel erosion and accelerated channel migration.
The stream restoration design team includes County staff from Stormwater Planning Division, Maintenance and Stormwater Planning Division, Utilities Design and Construction Division, Urban and Community Forestry Division, Park Authority, Wastewater Collection Division, Land Acquisition Division, Wetland Studies and Solutions, Inc. (design engineering consultant), residents along the project area, Civic Associations and other stakeholders within the community.
The Kirk Park pedestrian bridge crosses the North Branch of Little Hunting Creek, connecting existing Fairfax County Park Authority (FCPA) trails between Candlewood Drive, Karl Road and Colonial Woods Drive. The existing pedestrian bridge was installed several decades ago by an unknown party. Fairfax County subsequently assumed operation and maintenance responsibilities for the bridge, in coordination with the FCPA. The bridge was removed by Fairfax County Maintenance and Stormwater Management Division (MSMD) because of its significantly deteriorated condition. MSMD is implementing pedestrian bridge replacement project. Completion of the bridge construction is scheduled for Winter, 2025.
The goal of the project is to improve water quality through restoration of approximately 12,000 feet of Paul Spring Branch and the North Fork of Little Hunting Creek, tributaries, stormwater outfalls and the floodplain within the stream valley between Mason Hill Drive, Sherwood Hall Road and Collingwood Road.
The project goal will be achieved by:
Grade control structures to be installed within the stream channel will mimic bedrock outcrops and beaver dams, and may include rock sills, cross vanes, step pools, riffles, boulder riffles and large woody debris jams. These engineered grade control structures are made of boulders, clay, logs, limbs, geotextile fabric and reinforced bed material.
The stream restoration design will minimize disturbance to the existing natural resources by:

Pre-Design
The benefits of this project include the protection of property, health and safety, and improvement of water quality.
County staff is restarting the assessment and design phase of the project with a new engineering design consultant, Wetlands Studies and Solutions, Inc. (WSSI). Community outreach efforts for the project will continue after stream assessment and pre-conceptual design deliverables are submitted to the County in Spring, 2025. Virtual and in-person community meetings will also be scheduled for review and feedback on the 35% concept design, 65% preliminary design, 95% final design. County staff will also continue to be available to meet with civic associations, small groups of residents, individual residents and other stakeholders to best understand the community’s concerns and receive feedback on the project implementation.
All community members are welcome and encouraged to participate in the project design review meetings. Additionally, a small group of volunteers from the community will be sought to work with County staff on a project Stream Team. Stream Team volunteers will be invited to attend more in-depth design development working meetings and field validation. Stream Team members will also serve as community liaisons to expand community participation and project outreach efforts through sharing design development insights with the community and providing feedback from the community to the County to help inform and shape the project implementation process. Project assessment and plan set deliverables will be made available in digital format when feasible and in physical copy in the Reference Section of the Sherwood Regional Library.
A pre-construction meeting for the community will be scheduled ahead of the Notice to Proceed being issued to the contractor, which will occur following the contractor prequalification and low-bid contract procurement process. Once construction is underway, County staff will provide thorough coordination and construction inspection on a daily basis, hold weekly progress meetings with the contractor and design/inspection staff, attend community construction progress meetings as needed/requested, offer a post-construction site walk for the community, and continue to provide project coordination and monitoring efforts to ensure success of the constructed project and installed native vegetation.
Design and construction of the new Kirk Park Pedestrian Bridge Project is being managed by Fairfax County Maintenance and Stormwater Management Division (MSMD) as a separate project. MSMD staff will coordinate to identify opportunities to limit construction activities within Kirk Park and the community while also providing for timely implementation and installation of the new pedestrian bridge.
Example of the type of pedestrian bridge which may be installed in Kirk Park:
The project costs are funded by the County’s Stormwater Service District. The design task order with WSSI was approved for $1,345,000. Funding for construction of the project is separate from the design task order approval and will be dependent of future budget allocation and prioritization. The cost of the construction will be determined after bids are received for the construction contract authorization in Winter, 2026.
Community Meetings for the project will be scheduled after the design task order and schedule is authorized and the stream assessment and pre-design deliverables are submitted to the County.
