To protect the public health, safety, and welfare in regard to hillsides and hillside development;

§ 30.9.20 Permitted uses and conditional uses.
Land in the RH residential hillside district may be used as provided in the residential use table, section 30.11.10(c). Other uses may be approved according to planned unit development (PUD) approval which shall be obtained according to the provisions of section 30.50.50.

§ 30.9.30 Site and building requirements.
(a)
Setback Requirements. All setback requirements shall be as specified in the planned unit development (PUD) approval which shall be obtained according to the provisions of section 30.50.50. RH residential hillside district lots exempt from obtaining PUD approval in accordance with section 30.9.70, Exceptions, shall comply with the minimum setback requirements established for the R1 single-family residential zoning district.
(b)
Building Visibility and Height Requirements. No structure shall be constructed in any hillside zone in such a way that it is silhouetted against the skyline when viewed from the valley floor below the hillside. Structures shall be limited to a maximum height of thirty (30) feet measured from grade along the perimeter of the dwelling to the ridge of the roof, except that any structure built so that the peak of the roof is within twenty (20) feet in height of the hillside ridge line shall be limited to fifteen (15) feet in height. If the structure is screened by existing trees or vegetation, it shall be limited to thirty (30) feet in height and two (2) stories at any one (1) point. No existing trees or vegetation may be removed except according to the provisions of the planned unit development (PUD) or architectural and site review approval.
(c)
Slope Requirements. No construction of any building shall occur on any portion of any parcel where the average slope of that portion covered by the structure exceeds thirty percent (30%) slope. For slopes over fifteen percent (15%), a special foundation design based on soils tests approved by the chief building official shall be required in order to preserve the integrity of the hillside slope.
(d)
Additional Requirements. Any additional requirements including, but not limited to, parking, signing, landscaping and fence requirements, shall be as specified in the planned unit development (PUD) approval which shall be obtained according to the provisions of section 30.50.50.

§ 30.9.40 Density.
The number of acres per dwelling unit (a) shall be determined by the average slope (s) based on the formula:
a = | 1 1 - .02s | - | 3 4 |
with a maximum of two (2) acres/unit. The number of dwelling units allowed for development on a given parcel would be calculated by the formula:
A (acres) a (acres/unit) |
