18.34.035 Exclusions of Areas from Slope Calculations, as Applied to Subdivisions, Lot Line Adjustments, and Multiple-Unit Residential Development.
A. For the purposes of determining the minimum lot area per dwelling and the allowed density, the owner may elect to exclude portions of the site from that considered in the calculations of average slope. No more than three (3) such portions of a site may be excluded from these calculations. Each area so excluded must be delineated using five (5) or fewer straight lines and may in addition include the property lines.
B. If the owner makes this election the following requirements apply:
1. The land excluded from calculation must remain undeveloped and a deed restriction assuring this provision, in a form acceptable to the City, must be recorded.
2. Only twenty (20) percent of the density which would be allowed for the area excluded, given its slope and size, may be added to that of the remainder of the property to determine the overall density or satisfy the minimum lot area per unit requirement.
3. The portions of the site excluded from slope calculations shall not be considered when calculating the natural state of the site.
C. This provision does not apply to the calculations of average slope for the purposes of determining if a use permit is required. (Ord. 1030 § 2(12), 2018; Ord. 934 § 2, 2004; Ord. 929 § 28, 2004; Ord. 689 § 3, 1983)
