1 MOSCONE EXPANSION PROJECT Yerba Buena Alliance PRESENTATION FEBRUARY 06, 2014

2 MOSCONE EXPANSION PROJECT OBJECTIVES Expand the contiguous exhibition space increasing the quantity of highly flexible meeting and ballroom spaces. Maintain continuous operations during improvement and expansion. Capitalize on Moscone s unique location in the city by improving its connections and relationship to the city s fabric: Activate streets by optimizing vehicular and service functions to create uninterrupted pedestrian-favored sidewalks fronted by active uses wherever possible. Enhance pedestrian circulation and interest by reintroducing lost mid-block passageways and reducing the length of uninterrupted frontages. Create new and improved connections to the Yerba Buena Gardens. Maximize the value of the City s infrastructure and urban planning investment by building at an appropriately high density. Improve Moscone s civic presence on Howard Street by creating an iconic and architecturally significant arrival experience. 2
