Construction

The outfall at S Kensington Street and 5th Road South leads to a small stream in the Upper Long Branch watershed, near Long Branch Nature Center. The outfall is a high priority for repair due to severe active erosion and broken and damaged stormwater pipes. The project will create a stable outfall, repair infrastructure, stabilize an 8-foot drop in the stream channel, remove invasives and plant native plants, and recreate the connection from the Moses Ball Spring to the stream. Thank you to the neighbors and stakeholders who engaged throughout the project process and helped shape the project design.  

Construction on the outfall repair began in May 2026 with site preparations and setup. Construction is expected to last approximately 6-9 months. The team is very aware of the children and pedestrians who frequent the area and will work to ensure safety throughout construction. Key project impacts can include:

• Parking restrictions: Residents may be asked to refrain from parking in certain nearby areas during working hours. Signage will be posted in advance.
• Other temporary disruptions can include noise, dust, and traffic.  
• Work hours will adhere to the County noise ordinance. Work will typically be conducted during the work week and will avoid County holidays. Exceptions are subject to County approval and will be shared with the community.

 Thank you for your patience and understanding as the construction phase of this project begins. For additional questions or to receive project updates, please reach out to Lily Whitesell at LWhitesell@arlingtonva.us.
