PC MINS 19770106M I N U T E S Planning Commission Work Session January 6, 1977 The meeting was called to order at 7:45 p.m. PRESENT: Hughes, McTaggart, Shaw ABSENT: Blue, Rosenberg Also present was Director of Planning Sharon Hightower. The staff re -draft of the grading ordinance (except section 9667, E) was discussed. Commissioner Hughes submitted a print-out titled "Yard Widths vs. Retaining Wall Heights" (attached). The Commission agreed on Alternative No. 1, the S (average percent slope) formula. Re downslope = 42 inches, upslope = 8 feet, they would try it on some odd lots to see if it would work. Re driveways, 5 -foot retaining walls would be -'all right. They felt they needed some definitions of minor projects with exist- ing residences not requiring complete grading approval. A work session was scheduled for Thursday, January 13, 1977. The meeting was adjourned at 10:00 p.m. to the meeting of January 11, 1977. , .. �� .
