In addition to the objectives prescribed in HMC § 20.04.010, the Hillside Overlay is included in the Land Use Code to achieve the following purposes:
A. 
Preserve the natural beauty of the hillsides and avoid storm drainage problems by encouraging the retention of natural vegetation and discouraging mass grading.
B. 
Allow adequate spaces for driveway access to steep sites.
C. 
Prevent loss of views, privacy, sunlight that would occur if dwellings on hillsides were located as close together as dwellings on level terrain.
(Ord. 950 § 2 (Exh. A § 1300), 1998)
A Hillside Overlay may be combined with any residential district. All regulations for the residential district shall apply except as provided by this article.
(Ord. 950 § 2 (Exh. A § 1305), 1998)
For each one foot of difference in elevation greater than 10 feet between points A and B described in this section, the minimum required lot area and lot width for a lot within a Hillside Overlay shall be increased three percent over the minimum area and minimum width prescribed in the base residential zoning district.
Point A is the point at which a projected side lot line intersects the edge of the existing roadway. Point B is the point on the site 100 feet distant from Point A with the greatest difference in elevation.
(Ord. 950 § 2 (Exh. A § 1310), 1998)
