NEW PERMIT APPROVALS
San Francisco Planning Commission approved in July 2019 the permits to install new TV antennas mandated by the Federal Communications Commission, and to strengthen certain structural elements of the tower. This work will continue into 2020 so Bay Area stations can meet nationwide go-live deadlines for “repacking” broadcast signals into a smaller portion of the radio frequency spectrum, as 30% of bandwidth previously used by TV stations is shifted to wireless.

WIND LOAD PERMIT APPLICATION
As a condition of the repacking permit, Sutro Tower, Inc. will comply with building codes that include managing the forces of winds of more than 100 mph. The safest way to meet this requirement is to reduce the tower’s weight and lessen the wind forces. Therefore, Sutro Tower, Inc. has submitted a permit application to the San Francisco Planning Department to remove hundreds of siding panels from the structure’s legs by 2023 – creating “open truss legs” similar to the Eiffel Tower and most bridges.
