Backers of a plan to replace a condemned parcel next to the Fairmount train station with a 27-unit apartment building hold yet another public meeting to discuss the plans on Wednesday at 6:30 p.m. at the Hyde Park municipal building on River Street.

The Southwest Boston Community Development Corp., which proposed the apartments, has already had two public meetings on the plan. Although the plans have not changed in the year since they first became public, proponents will hold the third because ISD says the project needs two variances from the Zoning Board of Appeals, not the one the CDC originally thought.
