Deep Infrastructure
1. Design applications- not structures
application = systems at the service of the human condition
a structure an application
2. Ask for more
parking, stormwater management, lighting, biofiltration,
pedestrian pathway, carbon sequestration, vegetative buffer,
Beautiful.
3. Change the process
architect’s sketch
engineer’s sketch
the result
4. Think mechanically simple; ecologically complex

Ask for more:Divert three million gallons of stormwater
from the entering the Schuylkill RiverImprove connections from the island to
local businessesManage every reasonable drop of rain that
falls onto the Island Maintain two hundred parking spaces to
serve business communityImprove the facilities used by local
stakeholdersDevelop new active recreation
opportunities Improve connections to the riverImprove the Island’s ability to recover from
