what is green infrastructure?

Introduction

3. CREATING A GREEN INFRASTRUCTURE PLAN

1) educate the public

OSS2100 included many public lectures, articles, and eventsLFP Legacy had a Green Infrastructure Festival

Robert Garcia, The City Project: New Open Spaces for Social Justice in Los Angeles

Patrick Condon, Green Urban Infrastructure for the 21st Century

Mark Childs, Designing Compelling Public Places

Mike Houck, Creating Livable Cities with Urban Green Space

1) educate the public

OSS2100 linked the effort to Seattle’s history and current imperatives around growth, public health, and global warming

from the Cascade Agenda by the Cascade Land Conservancy

Olmsted Brothers plan

2) choose your units

what will be your planning unit?

what is the scale?

2) choose your units

corridors can have units too

2) choose your units

3) discover the anatomy of the landscape

what are your existing green infrastructure elements?what is missing? what would make the system whole?

OSS2100 Technical Panels: Development, Biodiversity, Waters of Puget Sound, Future Scenarios, Seattle Parks, Climate Change, Transportation Futures

4) develop a long-term vision

OSS2100 Green Futures Charrette: 350 people x 3 days

4) develop a long-term vision

watershed by watershed, system by system
