design, such as increased buffers with native forest and vegetation. ii. Integrate trail systems and other non-motorized connections within open space areas to increase connectivity where feasible. iii. Integrate green infrastructure using low-impact development techniques into the design of open space areas.
unsafe, or a disturbance to a wildlife corridor or salmonid-bearing stream in a ravine.
5. Neighborhood Buffers
a. Design Intent
To integrate buffers into the design of neighborhoods and homesites that contribute positively to the character of Sammamish for all developments.
b. Design Standards
4. Open Space Tracts
i. Buffers should maximize the preservation of mature forest and native vegetation when determining the appropriate locations. ii. Where there is no mature vegetation, buffers should be landscaped with substantial drought-tolerant native vegetation that will provide a year-round screen between traffic and homes. Pedestrian trails are allowed in buffers. iii. Buffers should provide benefits to individual homesites such as increased privacy, shading, minimized noise impacts, improved mobility for non-motorized travel, and improved aesthetics.
a. Design Intent
The design intent is to allow for larger open space tracts where there are clear public benefits, such as preserving wildlife habitat corridors, extending natural features with off-site connections, preserving mature forest and native vegetation, trail connections, and passive open space opportunities.
b. Design Standards
i. Open space tracts should not be provided for the purposes of reducing development costs, in cases where they prohibit necessary street or non- motorized connections, or where a clear public benefit is lacking. ii. Open space tracts should be provided on lands that have existing mature forest and native vegetation. iii. Open space tracts must be accessible as passive open space unless determined to be infeasible,
6. Recreation + Trails
a. Design Intent
To maximize opportunities for recreation and trails, enhance neighborhood connectivity and expand access to recreation land and facilities.
