30.41H.080 Performance standards – site design.
Rural village housing demonstration program development applications shall comply with the following requirements:
(1) Rural Open Space. A minimum of 85 percent of the site shall be in permanent open space tracts that preserve elements of rural character. These includes tracts that protect habitat, critical areas and buffers, and resource-based activities including agricultural production and working forest lands. The following uses and facilities may be included within the minimum 85 percent open space requirement:
(a) Wildlife corridors;
(b) Nature interpretive areas;
(c) Bird watching facilities and structures;
(d) Tree stands, duck blinds, and similar hunting structures if the site does not appear within the No Shooting Areas designation on the No Shooting Areas map for Snohomish County;
(e) Unimproved trails;
(f) Public access to shoreline areas subject to the shoreline management program;
(g) Landscaping areas, including landscaping for screening purposes; and
(h) Similar natural conservation uses.
(2) Other Open Space. Open space tracts that include uses or facilities not described in SCC 30.41H.080(1) shall not be counted towards the 85 percent permanent open space tract requirement. Examples include, but are not limited to, tracts for private roads, parking areas, or other types of built environment, and narrow strips of land interspersed between residential uses.
(3) Density and lot yield. Density and lot yield shall be calculated as follows:
(a) The gross density (maximum number of dwelling units) shall be obtained by dividing the gross site area in square feet by 148,148. Whenever the resulting yield results in a fractional equivalent of 0.5 or more, the yield shall be rounded up to the next whole number; fractions of less than 0.5 shall be rounded down.
(b) A lot may contain non-residential uses or residential uses including individual dwelling units or an entire cluster of dwelling units as described in SCC 30.41H.080(4).
(c) Clusters of dwelling units may be subdivided, including as phased subdivisions, into unit lots per SCC 30.41A.205 if shown on the preliminary plat map submitted under this chapter. Townhouse and duplex dwellings that were shown on the preliminary plat map as multiple units on a single lot may be subsequently subdivided under SCC 30.41A.205 or 30.41B.205.
(d) The number of lots for residential purposes shall not exceed the maximum number of units.
(e) Any lots proposed for non-residential purposes shall be indicated as such on the face of the plat and shall have restrictive covenants preventing placement of dwelling units on the lot.
(4) Clustering. Site design shall use clustering of dwelling units to protect critical areas and their buffers, resource-based activities, or other existing features that help maintain and establish rural character on the site.
(a) A rural village housing demonstration program development may contain more than one cluster of dwelling units.
(b) The minimum number of dwelling units in a cluster shall be 10. The maximum number of dwelling units in a cluster shall be 40.
(c) Clusters shall be located a minimum of 100 feet from adjacent natural resource lands subject to chapters 30.32A, 30.32B, or 30.32C SCC.
(d) Clusters shall be separated by open space tracts that create a minimum 200-foot spacing between clusters. (Added by Ord. 23-051, June 14, 2023, Eff date June 26, 2023).
