9293.8. - Development standards for hillside lots.

The hillside standards in division 2 of part 2 of chapter 6 of article IX shall not apply to housing development applications submitted pursuant to this part. Instead, development on any parcel having an average slope of greater than ten (10) percent shall meet the following standards:

A.

In determining the average slope of a property, areas with a slope percentage greater than thirty-five (35) percent shall be excluded, and no development or soil disturbance activities shall occur on slopes greater than thirty-five (35) percent unless it is required to provide access roads to a dwelling unit.

B.

All manufactured slopes or the face of cut-and-fill slopes shall be planted or otherwise protected from the effects of storm runoff and erosion within thirty (30) days after the completion of grading.

C.

Where the average elevation of the rear lot line is higher than the average elevation of the front lot line, no building or structure shall exceed a height of fifteen (15) feet above the average finished grade of the rear yard lot line. Where the average elevation of the rear lot line is below the average elevation of the front lot line, no building or structure shall exceed a height of fifteen (15) feet above the average elevation of the front lot line. The purpose of this standard is to locate development lower on hillsides in order to preserve viewsheds. On uniquely shaped convex lots where the strict application of this standard would prohibit the reasonable development of the lot, this standard shall not apply.

D.

Structures shall be located with a minimum building setback of twenty (20) feet from the top of a slope greater than ten (10) percent.

E.

Stilt and cantilevered structures are prohibited in the very high fire hazard severity zone (VHFHSZ).

F.

Any necessary upgrades or construction of new stormwater drainage facilities shall be designed in compliance with Los Angeles County Flood Control District (County Public Works Department) objective standards, and in compliance with state and federal law.

G.

The average slope of a parcel of land shall be calculated using the methodology outlined in section 9652.12.B. of the Agoura Hills Municipal Code.
