Document Description
After the City and County of San Francisco adopted the Final Mitigated Negative Declaration (FMND) for the 301 Mission Street (Millennium Tower) Perimeter Pile Upgrade Project, case number 2018-016691ENV, and approved the project (“adopted project”) on July 17, 2020, the project sponsor revised the project. The 301 Mission Street Modified Perimeter Pile Upgrade Project (“modified project”) would be substantially similar in scope to the adopted project, except that the modified project would install 18 new piles including 12 piles along Fremont Street and 6 piles along Mission Street (as opposed to 52 piles under the adopted project), and that the total mat extension area would be reduced from 2,130 square feet under the adopted project to approximately 1,020 square feet under the modified project. In addition, changes to the permitted shoring and excavation permits include the following: (1) reduction in plan area of excavations on Mission and Fremont streets, based on the
reduction in the number of new piles from 52 to 18, (2) change from the use of jet-grouted columns to a secant pile wall system for supporting the excavation, and (3) modification of shoring wall layout to avoid conflicts with the existing PG&E vault and power conduits at the northwest corner of the existing 301 Mission Street building.
