a. Forest
b. Stormwater/Green Infrastructure
Forest is the required frontage type on sites that have mature trees and native vegetation that can be preserved. The forest buffer shall be a minimum of 100’ or the depth of the mature forest from the arterial street right-of-way, whichever is less. The minimum forest buffer is 50’. If the arterial frontage is deforested`, then reforestation is also an option consistent with the City of Sammamish’s Urban Forest Management Plan. Applicants must submit a reforestation plan by a certified arborist or other qualified expert for review and approval by the City.
The stormwater/green infrastructure frontage type must have a minimum depth of 100’ and be designed for both stormwater functions and as an open space amenity using native vegetation and the incorporation of natural habitat features. The diagram below shows a stormwater pond fronting on an arterial street with street trees, natural fencing, and native vegetation which serves as a visual and physical amenity.
