The San Francisco Planning and the Recreation and Park Commissions have agreed that the shadow of the proposed Transbay Tower at 101 First St. won't have a significant or adverse impact on those public spaces.

To meet the previous ban on new shadows, about 500 feet would have been trimmed from the proposed 1,070-foot (326-meter) tall tower.

"The decision, made at a joint meeting of the two commissions Thursday, changes the rules for new shadows on city parks," The San Francisco Gate reports. "While 1984's Proposition K, known as the sunlight ordinance, essentially barred construction of any new building taller than 40 feet that cast shadows on city parks and playgrounds, the rules implementing the initiative measure were adopted by the Recreation and Park Commission in 1989."
