Integrate and Highlight Green Infrastructure Practices

INTENT

Landscape design is expected to embrace hydrological functions and reduce the impact of development with green infrastructure. Green spaces offer opportunities for water treatment, infiltration and storage on developed sites in order protect water quality, relieve the burden on stormwater infrastructure, and reduce water use and heating and cooling costs.

Guidelines

a. Preserve or restore hydrological functions of the natural landscape, improving stormwater quality through sustainable landscape and civil design practices including stormwater retention and infiltration where appropriate

b. Use green stormwater infrastructure (GSI) strategies to reduce flooding by slowing and reducing stormwater discharges

c. Include vegetative roofs and permeable paving for on-site stormwater management

d. Capture rainwater for reuse for irrigation

Residential entries at the Expo in Seattle are lined with rain gardens that reduce development impacts while creating a balance of private, semi-private and public spaces.

Redmond's Central Connector captures and treats runoff from a 250-acre area downtown with sustainable landscaping that helps create a distinct public space.
