What’s happening in Cambridge Crossing and at the Millers River affordable apartments?

bullet-gray-small Planning Board, from 6:30 to 8:30 p.m. Tuesday

Two big projects get a look from the board, including design review approval for a building with up to 500 units of housing, two retail pavilions and open space in Cambridge Crossing, the growing neighborhood formerly known as NorthPoint. DivcoWest’s presentation was delayed from March 27.

The comprehensive permit to renovate the affordable Millers River Apartments high-rise (and add two units, for a total 300 “deeply affordable apartments” on site) and create a community center addition with a roof garden arrives as a Board of Zoning Appeal case. The developers want to reduce vehicle parking, add less bicycle parking than what’s required by law and to be exempt from the citizen-proposed “green factor” zoning intended to help prepare the city for climate change.

The board meets on the second floor of the City Hall Annex, 344 Broadway, Mid-Cambridge.


What’s happening in Kendall Square?

The design proposal for a temporary Bank of America trailer will take up the first hour and a half of the long evening. With the cancellation of a meeting last month, this agency focused on Kendall Square likely plans to pick up that unaddressed agenda at 5:30 p.m. That should include talking about plans to transform 105,200 square feet of existing office and lab space into lower-cost innovation space for techy start-ups at 255 Main St., a prominent, accessible space next to a T stop and across from Point Park at Broadway and Main Street.

The agency meets at the Cambridge Police Department, 125 Sixth St., East Cambridge, near Kendall Square.
