Concord’s Steeplegate Mall Redevelopment

Redevelopment plans for Steeplegate Mall that include a Costco and a Whole Foods supermarket as well as some 600 housing units are moving ahead now that a Massachusetts developer has purchased the site.

An initial Planning Board hearing is set for Wednesday.

The mixed-use proposal to replace the Steeplegate Mall and adjacent Regal Cinema is one of the biggest that Concord has seen in years.
