E.
Lot Coverage
Lot coverage (expressed as a percentage of lot area) shall be determined by measuring the total
horizontal land area (in acres or square feet) covered by all solid surfaces (hard surfaces and buildings)
on the lot, dividing that coverage area by the lot area, and multiplying the result by 100.
F.
Structure Height
The height of a structure shall be determined
by measuring the vertical distance from the
mean elevation of the finished grade at the
base of the front of the building up to:
The highest point of the deck line for a flat
roof;
The mean height level between eave and
ridge for a gable, hip, cone, gambrel, or
pyramid roof;
The deck line of a mansard roof; or
The highest point of a shed roof. (See
Figure
11.4.1.F:General Height
Measurement.)

G.
Setback
Generally
Front, corner side, side, and rear setbacks
on a lot shall be determined by measuring
the horizontal distance along a straight
line extending at a right angle from the
lot’s front, corner side, side, or rear lot line
(as appropriate) to the foundation of the
nearest structure on the lot. (See Figure
11.4.1.B:Lot Dimensions.) The area
defined by a minimum setback and the lot
line from which it measured is a required
front, corner side, side, or rear yard (as
appropriate). Allowable encroachments
into required yards shall be ignored when
measuring setbacks (see Sectio
n 11.4.2.D, Allowable Encroachments into Required Yards).
Front and Corner Side Setbacks
a.
Corner Lot
(1)
On a corner lot, the front and corner side setbacks shall be measured—and the minimum
front and corner side setback requirements applied—from the front or corner side lot line,
as appropriate.
(2)
On a corner lot where the intersecting right-of-way boundaries are defined by a radius,
the front and corner side setbacks shall be measured—and the minimum front and corner
side setback requirements applied—from the front or corner side lot line, as appropriate,
