members of the City Council each supervise the various agencies of the city. When Potter took office, he declared that he was taking centralized control of all city bureaus for a period of six months. He later redistributed them once the adjustment period was completed. Potter advocated for a change to that system, advocating for a "strong mayor" initiative in the May 2007 election. The measure was defeated by a 3-1 margin.

One of his major progressive projects was working with latinx activists, as an ally, and making 39th avenue Cesar Chavez ave. In October 2006, Potter introduced a resolution affirming the City's commitment to the inclusion of immigrants and refugees in civic life, and
