Seattle, in an effort to compensate for missing greenery and open space, has approved a plan that “encourages a site-appropriate package of greening possibilities, including green roofs, interior green walls, exterior vertical landscaping, and rain gardens.”
The plan includes incentives for builders that use innovative green technologies in their buildings. Additionally, building owners would benefit from the added “building insulation, shading, air filtration, and stormwater runoff management” provided by green roofs and the like.
