Preliminary Assessment of San Francisco City Commissions’ and Boards’ Ethical Standards for Awarding Contracts as Part of Public Integrity Review

San Francisco, CA (January 11, 2021) —  The Controller's Office today released a preliminary assessment report on city commissions’ and boards’ ethical standards for awarding contracts, with a focus on the Airport Commission and Revenue and Development Management unit at San Francisco International Airport. This assessment was done because the allegations in the federal criminal complaint against former Public Works Director Mohammed Nuru identify former Airport Commissioner Linda Crayton as the target of an alleged bribery scheme by Mr. Nuru. Unlike with our other published public integrity assessments, to date our office has found no substantial structural problems with the procurement policies and procedures we examined.
