Project Background:

The project area was highlighted as an infrastructure enhancement location within 2010’s West Concord Master plan. The Plan recommended the following enhancements:

• Upgrade pedestrian safety at the intersection of Church Street and Commonwealth Avenue

• Create a pedestrian only zone between Concord Teacakes and Twin Seafoods

As such, the following project has been designed and issued by the Town for construction.

Project Overview:

The project scope of work consists of constructing a new concrete paver plaza gathering area within the sidewalk and alleyway between 59 Commonwealth Avenue (Concord Tea Cakes) and 7 Church Street (Twin Seafood). The project will also realign of the intersection of Church Street and Commonwealth Avenue to provide a bump out crosswalk configuration to improve pedestrian mobility. New ADA curb ramps will be installed with new ADA compliant sidewalks. Lastly, Mandrioli Park will be revitalized with new pavers, replanted garden beds / shade trees and a new drinking fountain.

The project’s design incorporates significant sustainable infrastructure components. The plaza area and Mandrioli Park will be reconstructed with a porous paver system. Additionally, the intersection area will be retrofitted with a new bio-retention garden to improve stormwater treatment.
