Seattle's decade of experience installing Green Infrastructure (GI) projects has provided a substantial knowledge base. Two key areas of growth will be discussed: 1) Key policy issues in the development of the Seattle's Stormwater Code requirement for use of GI to the “maximum extent feasible” for projects on private property and right-of-way, and 2) public engagement success, failures, and proposed approach in moving forward in installing GI in public and private places, including a look at using GI to assist with combined sewer overflows.
