Spring 2026 Project Update

The project team is wrapping up the current phase of the design process, incorporating valuable community feedback and adjusting the design. We anticipate the next project engagement will be in late May or June 2026. We look forward to engaging with the community on the next phase of the design.

Thank you to all who provided feedback on the Concord Mews pond project design options! We truly appreciate your thoughts and input. Ultimately, both immediate neighbors and the broader community favored the meandering wetland option, but all respondents provided important feedback and we will incorporate or address the feedback in our future engagement.

The Concord Mews pond repair will: 

• Replace outflow and inflow pipes, which are damaged and not functioning,
• Allow water to flow through the area, instead of being stagnant,
• Add a sediment collection area for easier maintenance,
• Capture and filter runoff, removing nutrients and sediment and protecting Four Mile Run,
• Replant a healthy and diverse forest with a variety of species and multiple layers of vegetation,
• Provide habitat for birds, ducks, turtles, tadpoles, dragonflies and pollinators,
• Include a natural look and feel with gently sloped sides. 

The meandering wetland option will have more well-defined meanders in the water flow path, medium tree impact, and more robust replanting. Additionally, more accumulated sediment and gravel will be removed, and it is anticipated to be easier to maintain and a longer-term solution for the area.

About the Project

The Concord Mews Pond was originally installed in the 1970s-80s to manage stormwater for Concord Mews Condominiums. It was designed to temporarily store and slowly release stormwater runoff. Over the years, the inflow and outflow pipes were damaged, and the area filled with sediment. 

The project approach will aim to:

• Restore the functionality (inflow, outflow, ponding area) so it captures and absorbs runoff and protects water quality,
• Ensure long-term stability and safety of the pond and berm, 
• Provide a wooded natural space and habitat for birds and pollinators.
