The Street Life Plan projects each fall into one of six categories: (1) anchoring the heart of the district, (2) promoting the alleys, (3) making new social spaces, (4) improving sidewalks for street life, (5) promoting walking and biking, (6) and promoting sustainability. This rendering shows the proposed redesign of Howard Street between 3rd and 4th streets, which connects two of the Moscone Center convention buildings. The space, currently serving through-traffic only, will be literal and social center of the district in the new plan.
