Circle Woods Sec 3 (0217DP) Pond Improvement

Project Number: SD-000033-106

Project Background

This maintenance project was started on the Circle Woods Sec 3 detention pond after dam and control structure deficiencies were identified during maintenance operations. Staff from the Maintenance and Stormwater Management Division (MSMD) initiated a design project to perform dam safety and permit required repairs as well as make improvements to the facility function. This project is part of the Fairfax County Stormwater Facility Maintenance Program.

Project Description

The maintenance project will include necessary repairs to the existing Circle Woods Sec 3 (0217DP) detention pond dam, replacement of the pond’s control structure, removal of sediment and other facility repairs/improvements. Piping conditions have been observed through the dam from extensive tree root structure in the embankment which was the main catalyst for the project. Trees and root structure will be removed from the dam embankment. The work will also include improved conveyance and outfall across the East Blake Lane Trail.
