B. Lots with Slopes of Ten (10) Percent or Greater.
1. For lots in the First and Second Residential Districts, for every one percent increase in average slope above ten (10) percent, the FAR decreases by one one-hundredth until forty-five (45) percent of slope is reached, after which there are no further decreases in the FAR regardless of the increase in the average slope. The minimum FAR is listed in the third column of Table 35-1.
2. For sloping lots in the Third Residential District, the floor area ratio shall be as set forth in Table 35-2.
3. Calculation of Slope.
a. For the purposes of this chapter, the slope of a property shall be calculated following the procedures of Larkspur Municipal Code Section 18.34.030.
b. Where a residence is to be constructed or improved on a portion of a parcel that has a lower average slope than the entire parcel, for the purpose of calculating the maximum floor area, a property owner may elect to split the parcel into two (2) portions and then calculate the slope, floor area ratio, and maximum floor area for each portion. The sum of the two (2) calculated floor areas would be the maximum floor area entitlement for such residence. The split portions must be divided by no more than three (3) connected straight lines and the entirety of all existing and proposed floor area must be located within the portion containing the lesser slope.
