Thanks to all who have participated in the community process for this planning effort. On December 10, 2008, a presentation was made to the community outlining the project background and the final traffic calming plan.

Speed Hump Ballot Results

The Final Report for this project area has called for the installation of one or more speed humps. Ballots for these speed humps were sent out in July 2010. Per the SFMTA Traffic Calming Guidelines, speed humps will be installed where a majority of residents on the block of the proposed speed hump voted in favor of the hump. The table below shows the percent of ballots returned for the block and the percent of those responses for and against each speed hump proposed in this project area.

Potrero Hill Speed Hump Ballot Results

Where respondents have approved a speed hump, we will now determine if there is a suitable location for its installation. If a location on the block is found to be consistent with SFMTA guidelines, we will then schedule a public hearing and post notices of the hearing on your block. Public hearing approval is required for any new speed hump construction.
