As Evergreen Walk prepares to welcome two prominent new tenants, South Windsor planners likely will decide Tuesday on a proposal for 165 apartments at the retail hub. The idea got extensive public support and only mild criticism at a recent hearing, and Town Manager Michael Maniscalco wrote that it will bring in an estimated $400,000 in new tax revenue. The planning and zoning commission in January rejected a previous version of the apartment plan, saying it wouldn’t benefit the town. The developer filed a lawsuit and submitted a revised proposal that it says addresses commissioners’ concerns; the lawsuit is still pending but is expected to be dropped if the new plan is approved. The commission is scheduled to vote Tuesday at 7 p.m. at council chambers in town hall.
