sq-winthropInformation made public this week provides more preliminary detail on the expected shadows that Millennium Partner’s proposed 750-foot tower at Boston’s Winthrop Square garage site could cast on Boston Common and the Public Garden — in violation of state laws enacted to protect the parks.

The $1.02 billion, 55-story tower would be in compliance with the shadow laws only on 101 days of the year for the Common and 254 days for the Public Garden, according to a Millennium presentation on Monday. It would cast shadows on the Common for 20 minutes or less for 113 days of the year.

Laws enacted in 1990 and 1992 dictate new buildings in that area only can cast shadows over the parks during the first hour after sunrise or before 7 a.m. — whichever is later — or the last hour before sunset.

The tower is expected to cast new morning shadows for as long as 90 minutes on the Common and 29 minutes on the Public Garden. No shadow would be cast past 9:25 a.m. on the Common and 8 a.m. on the Public Garden.
