PROJECT DESCRIPTION: PUBLIC LIBRARY
The project sponsor, the Planning Department, on behalf of the City and County of San Francisco, is
proposing the Mission District Streetscape Plan Project (MDSP). The San Francisco Planning Department
is the lead agency under the California Environmental Quality Act (CEQA). The Mission District
Streetscape Plan's ("MDSP or proposed project") general boundaries are Division Street to the north, U.S.
Highway 101 (U.S.-101) to the east, Precita Avenue/Mission Street/San Jose Avenue to the south, and
Dolores Street to the west. The MDSP is an overall streetscape vision for the Mission District. It includes
design framework and detailed policies, and site-specific streetscape improvement projects based on
those policies. The MDSP would provide a framework to implementthe policies ofthe MissionArea Plan
of the San Francisco General Plan, which was developed through the Eastern Neighborhoods planning
process and adopted by the City ofSan Francisco inDecember 2008. The MDSP does notinclude changes
to public open spaces under the jurisdiction of the Recreation and Parks Department. It does, however,
consider pedestrian and vehicular connections between such open spaces and the public right-of-ways.
The MDSP would involve the implementation of site-specific streetscape improvement projects in the
Mission District. These site-specific streetscape improvement projects are divided into two categories
based on street type: 1) Alleys and Small Streets Projects; and 2) Streetscape Improvement Projects.
Streetscape design elements to be implemented at specific locations under these two categories would
include: raised crosswalks for alleys/narrow streets atintersections; chicanes; plazaimprovements such as
distinctive paving or artwork; permeable paving; new street trees; stormwater planters and other
landscape improvements; bollards to demarcate protected pedestrian areas; seating; and pedestrian
lighting. Implementation of the site-specific streetscape improvement projects is intended to enhance the
public realm in the Mission District. For more information about the MDSP, please visit the MDSP
