(1) For any proposed

(2) For any proposed
within the
where the

, the minimum size required for that

unless a greater size is required by the underlying
. The amount of
permitted is indicated in Column D of Table 5.2-1, based on the area of the
, Column B.
(3) Yard

b. If a

created shall comply with Columns A, B, and D of Table 5.2-1.
B. Multifamily Residential
1. The

is 15% or greater, Columns A, B, C, and D of Table 5.2-1 applies.
2. Natural areas may be designated on the
or
, in accordance with Section 5.2.6, to reduce the
percentage. Such natural areas shall be excluded from the
calculation but shall be included for the
and
calculations. (See Figure 5.2-B.)
a. If the
of the remaining portion of the
or
is less than 15% and contains no areas of 15% or greater
, 100% of that portion may be graded, subject to Section 5.2.7.B.1.
b. If the
of the remaining portion of the
or
is less than 15% but contains areas of 15% or greater
, 80% of that portion may be graded.
c. If the
of the remaining portion of the
or
is 15% or greater, Columns B, C, and D of Table 5.2-1 apply, based on the entire area of the

percentage: 1. The area for septic tanks, including the primary and secondary leachate fields.
2. The area for the minimum area needed for a

C. Flexible Lot Development (FLD)
The purpose of the FLD in the HDZ is to preserve the sloped areas while encouraging
on the flatter portions of a
or
. An FLD shall meet the standards of Section 8.7.3, as well as the following standards: (See Figure 5.2-C.)
1. All
shall be located outside the 300-foot
or
and the protected area shall be preserved as a natural area as provided in Section 5.2.6, Natural Areas;
2. The FLD application may be used for either single-
or multifamily
. In order to apply the FLD, the
of the area to be developed shall be less than 15%. This may require excluding steeper
as natural areas in order to reduce the
of the remaining portion. Such natural areas shall be excluded from the
calculation but shall be included for
and
calculations.
shall be regulated by the underlying
, based on the entire area; and,
3. For property within the HDZ, sloped areas in excess of 15% with an area greater than or equal to 7,000 square feet shall be delineated and set aside as
and designated as common area.
D. Nonresidential
1. The
shall be calculated for the entire
or
. If the
is 15% or greater, Columns A, B, and D of Table 5.2-1 apply. Column C does not apply.
2. Natural areas may be designated on the
or
, in accordance with Section 5.2.6, to reduce the
percentage.
a. If the
of the remaining portion of the
or
is less than 15% and contains no areas of 15% or greater
, 100% of that portion may be graded, subject to Section 5.2.7.B.1.
b. If the
of the remaining portion of the
or
is less than 15% but contains areas of 15% or greater
, 80% of that portion may be graded.
c. If the
of the remaining portion of the
or
is 15% or greater, Columns B and D of Table 5.2-1 shall apply, based on the entire area of the
or
.
E. Mixed
When a mix of
