NATIONAL AND INTERNATIONAL MODELS LESSONS What design principles do the case studies share? • Mixed-use • Contextual buildings with streetwalls • Variety of architecture and variety of building heights • Streetscape that enhances the pedestrian experience • Great access supporting density and public uses • Responsive to climate and environment F E B R U A R Y 2 8 , 2 0 1 1 S E W A R D P A R K S E W A R D P A R K U R B A N D E S I G N U R B A N D E S I G N

SUMMARY • Reflect the significance of this crossroads of multiple neighborhoods with high quality urban design • Extend the mixed-use character of the surroundings throughout the development • Take inspiration from the best national and international models of similar scale and character • Provide a variety of architecture and building scales F E B R U A R Y 2 8 , 2 0 1 1 S E W A R D P A R K S E W A R D P A R K U R B A N D E S I G N U R B A N D E S I G N

URBAN DESIGN STEPS Four Steps to developing an initial urban design framework for the sites: Step 1 – Connections Step 2 – Density & Form Step 3 – Human Scale & Streetscape Step 4 – Identity & Program F E B R U A R Y 2 8 , 2 0 1 1 S E W A R D P A R K S E W A R D P A R K U R B A N D E S I G N U R B A N D E S I G N

URBAN DESIGN STEP 1 CONNECTIONS SUMMARY • Base site development on the street hierarchy • Reconnect the grid through the site • Restore pedestrian connections north to south and east to west • Frame view corridors • Weave together the urban fabric of the neighborhood F E B R U A R Y 2 8 , 2 0 1 1 S E W A R D P A R K U R B A N D E S I G N
