Portland, Ore.-based developer Gerding Edlen has received final approval for a $130-million, 258-unit apartment complex on the East Boston waterfront.

The developer recently revised the plans for 6-26 New St., replacing a previously approved new six-story building with a four-story addition to the renovated main building. The new plans, approved by the Boston Redevelopment Authority (BRA) Thursday, also eliminate a previously approved underground parking garage, replacing it with a three-story above-ground structure.

Development is starting to transform the Jeffries Point section of East Boston, on a series of former marine industrial parcels now being targeted for large-scale condo and luxury apartment projects. Developers are positioning the neighborhood as a less-expensive alternative to downtown and the Seaport, with a short commute to downtown via the MBTA’s Maverick station on the Blue Line.

In October, the first 175-unit apartment building will open at Portside at East Pier, which is being developed by Roseland Property Co. One-bedroom units are expected to rent for approximately $2,400. The property at 29 Marginal St. could eventually contain an additional 400 condos and 65,000 square feet of commercial space on a 26-acre site leased from Massport.

Winn Cos. of Boston is redrawing plans for Clippership Wharf, a waterfront parcel on Lewis Street where up to 400 condos and apartments are planned. Trinity Financial of Boston is seeking BRA approval for Boston East, a 200-unit residential project at 122-148 Border St.
