DESCRIPTION
The first of its kind in the US, Seattle Green Factor provides a flexible approach to building the city’s green infrastructure through development regulation. Basing its requirements on amount of functional systems rather than adherence to rigid standards is an innovative but untested approach, with unknown outcomes. (Functional Landscapes: Assessing Elements of Seattle Green Factor, the Berger Partnership, 2008)

The Green Factor system is designed to encourage larger plants, permeable paving, green roofs, vegetated walls, preservation of existing trees, and layering of vegetation along streets and other areas visible to the public. Bonuses are provided for food cultivation, native and drought-tolerant plants, and rainwater harvesting. (City of Seattle DPD)

Green elements in the landscape improve air quality, create habitat for birds and beneficial insects, and mitigate urban heat island effects. They also reduce stormwater runoff, protecting receiving waters and decreasing public infrastructure costs. (City of Seattle DPD)

Green Factor currently applies to new development in commercial and neighborhood commercial zones outside of downtown, and is proposed for multifamily residential zones and the South Downtown planning area. (City of Seattle DPD)
