In all districts and in connection with every
use, there shall be provided at the time any use or building is erected,
enlarged, extended or increased off-street parking stalls for all
vehicles in accordance with the following:
A. Access. Driveways shall be at least 10 feet wide for
one- and two-family dwellings and a minimum of 24 feet at the property
line for all other uses. Adequate access to a public street shall
be provided for each parking space.
B. Design standards. Each required off-street parking
space shall be not less than 180 square feet. No parking area of more
than four spaces shall be designed as to require any vehicle to back
into a public street. Large expanses of unchanneled parking areas
shall be avoided by interior landscaping and safety islands.
C. Location.
(1) Off-street parking shall be on the same lot as the
principal use or not over 400 feet from the principal use. No parking
stall or driveway, except in residential districts, shall be closer
than 25 feet to a residential district lot line or a street line opposite
a residential district.
(2) Off-street parking is permitted in all yards of all
districts except in the front yards of single-family and two-family
residence districts but shall not be closer than five feet to a side
lot line, right-of-way line or rear lot line.
D. Surfacing. All off-street parking areas and/or driveways
for more than five vehicles shall be surfaced with an asphaltic or
portland cement pavement in accordance with the Town of Trenton standards
and specifications so as to provide a durable and dust-free surface,
shall be so graded and drained as to dispose of all surface water
accumulated within the area and shall be so arranged and marked so
as to provide for orderly and safe loading or unloading, parking and
storage of self-propelled vehicles.
E. Landscaping. All public off-street parking areas which
serve five vehicles or more and are created or redesigned and rebuilt
subsequent to the adoption of this article shall be provided with
accessory landscape areas totaling not less than 5% of the surfaced
area. The minimum size of each landscape area shall not be less than
100 square feet. Location of landscape areas, plant materials, protection
afforded the plantings, including curbing, and provision for maintenance
shall be subject to approval by the Plan Commission. All plans for
such proposed parking areas shall include a topographic survey or
grading plan which shows existing and proposed grades and location
of improvements. The preservation of existing trees, shrubs and other
natural vegetation in the parking area may be included in the calculation
of the required minimum landscape area. Those parking areas for five
or more vehicles, if adjoining a residential use, shall be screened
from such use by a solid wall, fence, evergreen planting of equivalent
visual density or other effective means, built and maintained at a
minimum height of six feet.
F. Additional requirements.
(1) Repair and service. No motor vehicle repair work or
service of any kind shall be permitted in association with parking
facilities provided in residence districts.
(2) Lighting. Any lighting used to illuminate off-street
parking areas shall be directed away from residential properties and
public streets in such a way as not to create a nuisance. However,
in no case shall such lighting exceed three footcandles measured at
the lot line.
(3) Street setback area. No parking shall be permitted
between the street right-of-way line and the building setback line
prevailing in the zone in which the proposed parking area is to be
located. The resulting open area shall be planted in grass or otherwise
landscaped to create a permanent green area.
G. Curbs. Curbs or barriers shall be installed a minimum
of four feet from a property line so as to prevent the parked vehicles
from extending over any lot lines.
H. Number of stalls. The number of parking stalls required
is shown in the following subsections:
(1) Residential uses:
(a)
Single-family dwellings and two-family dwellings:
two spaces per dwelling unit.
(b)
Housing for the elderly: one space per dwelling
unit.
(2) Business, institutional and industrial uses: four
square feet of parking for each one square foot of gross building
area.
I. Combined uses. Combinations of any of the above uses
shall provide the total of the number of stalls required for each
individual use. Two or more uses may provide required off-street parking
spaces in a common parking facility less than the sum of the spaces
required for each use individually, provided that such uses are not
operated during the same hours. A written agreement satisfactory to
the Town Attorney shall accompany any joint use arrangement.
J. Handicapped parking requirements. In addition to any
other requirements relating to parking spaces contained in this Code,
the provisions contained in §§ 101.13, 346.503 and
346.56, Wis. Stats., and any Wisconsin Administrative Code sections
adopted pursuant thereto are hereby adopted by reference and made
applicable to all parking facilities whenever constructed. All open
off-street parking areas providing more than 25 spaces, except for
parking areas restricted to use by employees only, shall provide parking
spaces for use by motor vehicles which transport physically disabled
persons in accordance with the following minimum standards:
(1) One parking space shall be provided in parking areas
containing 26 to 49 spaces.
(2) Two percent of the total number of spaces shall be
provided in parking areas containing 50 to 1,000 spaces.
(3) In addition to the number of spaces required in Subsection
J(2) above, 1% of each 1,000 spaces over the first 1,000 spaces shall be provided for physically disabled parking.
(4) The minimum dimensions for all parking spaces provided
for use by physically disabled persons shall be 12 feet by 18 feet.
(5) Parking spaces provided for the use of physically
disabled persons shall be located as close as possible to an entrance
which allows such persons to enter and leave the parking area without
assistance.
(6) All parking spaces provided for the use of physically
disabled persons shall be marked by a sign which includes the international
symbol for barrier-free environments and a statement informing the
public that the parking space is reserved for use by physically disabled
persons, all according to law.
K. Changes in buildings or use. Whenever a building or
use is changed, structurally altered or enlarged to create a need
for an increase of 25% or more in the number of existing parking spaces,
such spaces shall be provided on the basis of the enlargement or change.
Whenever a building or use is enlarged to the extent of 50% or more
in the floor area, said building or use shall then comply with the
parking requirements set forth in the district in which it is located.
