Wednesday night, the Planning Board will hear plans for the redevelopment of the Watertown Mall and nearby properties planned by Alexandria Real Estate Equities.
Alexandria seeks a Master Plan Special Permit with Site Plan Review for what is known as the Watertown Mall Transformation Project. The plan calls for four office/lab buildings, a new retail building, two amenity spaces and two parking garages, including one that would be a separate project at 480 Arenal Way.
The application reads: “The proposed master plan would create a new mix of uses within a development that spans 4 existing parcels, carried out in phases, with laboratory/R&D, retail, office, commercial and amenity space within 8 buildings (Target/building to remain), with supporting structured and surface parking.”
The project includes the properties at 446-458, 500, and 550 Arsenal Street, which are located in the Regional Mixed Use District (RMUD). The district also includes Arsenal Yards. Because it is in the RMUD, the Planning Board will be the special permit granting authority for the master plan special permit.
The entire complex would have 974,754 sq. ft. of gross floor area within eight buildings, according to the application. It would also have six acres of publicly-accessible open space.
At 446/458 Arsenal Street, a five-story, 79-foot tall office/lab building with 117,500 sq. ft. of gross floor area would be constructed. The parcel would have nearly 43 percent open space.
Two five-story buildings are planned for 500 Arsenal Street that would have a combined 323,500 sq. ft. of gross floor area and a maximum height of 79-foot tall building. Fifty-seven percent of the parcel would be open space. An 8,000 sq. ft. amenity building is also planned in the plaza along Arsenal Street
A 79-foot tall building is planned for 550 Arsenal Street with 240,500 sq. ft. of gross floor area, along with a 94,000 sq. ft. retail building, and a 21,500 sq. ft. amenity building attached to a parking garage. The parcel also includes Target, which has 166,198 sq. ft. of gross floor area, as well as the existing bank in the surface parking area in front of the store. More than 20 percent of the parcel would be open space.
A parking garage would to go next to Target, and would have 1,180 parking spaces. There will also be 502 surface parking spaces.
In a second hearing on Wednesday, Alexandria will present plans to put up a six-level parking garage as part of the Watertown Mall Transformation Project. The garage would have 700 spaces and would be 57.1 feet tall.
The garage is planned to go next to the existing building at 480 Arsenal Way. The parcel will also have 148 surface parking spaces. Combined, the Arsenal Street and Arsenal Way parcels will have 2,530 parking spaces.
Because 480 Arsenal Way is in a Industrial 2 zone, the special permit granting authority will be the Zoning Board of Appeals.
The Planning Board will meet in the Council Chamber in City Hall, 149 Main St., on Wednesday, Aug. 9 at 7 p.m. The meeting will also be available for participation over Zoom, and be broadcast by Watertown Cable. See the agenda for more information (click here).
