SECTION 11.4. MEASUREMENT, EXCEPTIONS, AND VARIATIONS OF INTENSITY

AND DIMENSIONAL STANDARDS

11.4.1.

Measurement

Net Lot Area

Net lot area shall be determined

by measuring the total

horizontal land area (in acres or

square feet) within the lot lines

of the zoning lot, excluding

public street rights-of-way. For

purposes of determining net

density, any part of the net lot

area dedicated as recreation

area, park, greenway, or other

public open space in conjunction

with a development approval in

accordance with this Ordinance

shall continue to be considered

part of the net lot area of the

zoning lot.

(Ord. No. 2015-002, 04/29/2015)

Lot Width

Lot width shall be determined by

measuring the distance along a

line delineating the minimum

front setback applicable to the

lot, between its intersections with

the side lot lines, or for corner lots, between a corner side lot line and the opposite side lot line. (See

Figure

11.4.1.B:

Lot Dimensions.)

Net Density (Dwelling Units per Acre)

Net density (expressed as dwelling units per acre) shall be determined by dividing the total number

of dwelling units located or proposed on a lot by the net lot area (see subsection

above). If net

lot area is measured in square feet, that result shall be multiplied by 43,560. For purposes of

determining maximum net density, an accessory apartment shall not count as a dwelling unit.

Maximum net density standards apply only to development comprised of dwelling uses (e.g.,

household living uses). For a mixed-use development containing dwelling units and nonresidential

or non-dwelling principal uses, net density shall be determined by dividing the total number of

dwelling units located or proposed on the lot by that portion of the net lot area allocated to the

dwelling uses (and not allocated to nonresidential or non-dwelling uses).

Floor Area Ratio

Floor area ratio shall be determined by measuring the gross floor area (in square feet) devoted to

nonresidential and non-dwelling uses on all floors of all buildings located or proposed on a lot by the

net lot area (in square feet) (see subsection

above).
