Opportunistic Park(ing): A Distributed Pedestrian Network
SITE ANALYSIS: Powell BART Station & Context
Thesis 2012: California College of the Arts Instructor: Brian Price This thesis proposes ulterior public space within the city.

The research has focused on where current policy for public space making is ineffective and where there are opportunities to propose alternative strategies in both locating and implementing these spaces.
BOEDDEKER PARK
This design experiment exploits an economy of means both politically and conceptually to illuminate how policy may be augmented to produce public space that will better serve the city.

STRATEGIES TO ENCOURAGE OCCUPATION OF PUBLIC SPACE:
-DETERMINE FACTORS THAT CONTRUBUTE TO UNDERUTILIZED PUBLIC SPACE -LOCATE AREAS OF THE CITY WITH BELOW-AVERAGE OPEN SPACE -LOCATE AREAS OF THE CITY WITH HIGH POPULATION DENSITY
-USE OF MATERIALS ASSOCIATED WITH OPEN SPACES -PROVIDE CIRCULATION ROUTES THROUGH THE SPACE

IDENTIFY URBAN STRATEGIES FOR NEW PUBLIC SPACE:
METHODS OF INTEGRATING NEW SPACES WITH PARKING PROGRAM:
-STREET LEVEL PARKING LOTS USED AS SITES FOR NEW OPEN SPACE INCREASE PUBLIC SPACE SQ. FOOTAGE TO CITY AVERAGE 17 % -THESE SPACES CAN BE CONNECTED WITHIN EACH BLOCK THROUGH MINIMAL SURGICAL CUTS IN THE URBAN FABRIC USING SITE LINES
-DEVELOP PUBLIC SPACE ABOVE EXISTING STREET LEVEL PARKING LOTS -USE A STRUCTURAL GRID THAT IS COMPATIBLE WITH THE PARKING LOTS BELOW -ALLOW FOR FLEXIBILITY WITHIN THE NEW SURFACE OF PUBLIC SPACE FOR LIGHT AND AIR AS WELL AS SECTIONAL CONNECTIVITY

DEVELOP PROGRAMMING STRATEGIES FOR MULTIPLE SCALES:
EAST-WEST SECTION SHOWING CONTIGUOUS PUBLIC SPACE:
-BASED ON THE STRUCTURAL GRID, EACH NEW SPACE IS SUBDIVIDED -DENSITY INCREASES AT THE EDGE AND PINCH POINTS FOR FLEXIBILITY -GREATEST FLEXIBILITY OCCURES AT CONNECTIONS TO EXISTING SIDEWALKS
-SURGICAL CUTS ARE MADE THROUGH EXISTING BUILDINGS WITHIN THE BLOCK -PARKING LOTS ARE MAINTAINED AND EVEN DEVELOPED AS COVERED PARKING -NEW FRONTAGES ARE CREATED BY THE SITE LINE CUTS THAT HELP TO ACTIVATE THE SPACE

Provide an open frame work for programming and interaction, as with KGDVS & Dogma Architecture's urban strategy for Seoul, Korea (2). - Provide a pedestrian thoroughfare as an alternative to, or extension of the sidewalk, expanding and contracting into a variety of public spaces. These strategies are exemplified in the Highline, by Diller Scofidio Renfro and James Corner Field Operations (3).
