The Mission Rock Project, a 28-acre mixed-use development at Seawall Lot 337 in San Francisco, sought an amendment to its Housing Plan. The amendment, approved by the Port Commission and recommended for approval by the Board of Supervisors, reduces the minimum percentage of inclusionary affordable housing units per Project Phase from 30% to 20%. This change primarily affects Parcel A, where higher-income AMI units (120% and 150%) have been difficult to lease, leading to vacancies. The modification aims to convert unleased 150% AMI units to 120% AMI and 90% AMI units, and 120% AMI units to 90% AMI units, while increasing market-rate units to improve leasing and project feasibility. The total BMR units for Phase 1 are reduced from 161 to 132 out of 537 residential units, changing the overall Phase 1 BMR percentage from 30% to 25%.
