on which any building may hereafter be erected or changed
in use, except as hereinafter provided. (Code 1959, § 20-1.)
Sec. 20-2. Area exempt from requirements of chapter.
The following area within the city is exempt and excluded
from the requirements of this chapter:
square feet and one space for each two hundred square feet of
retail sales area above five thousand square feet.
(5) Furniture and hardware stores, wholesale establishments,
machinery or equipment sales and service establishments,
clothing repair and shoe repair establishments: Two parking
spaces for the first one thousand square feet plus an additional
space for each four hundred square feet of floor area over one
thousand square feet.
(6) For all other commercial buildings not herein specified,
there shall be provided one parking space for each one
hundred square feet of gross floor area on the first floor, plus one
parking space for each five hundred square feet of gross floor
area on the upper floors.
(7) Rebound tumbling centers: Two spaces for each rebound
tumbler unit.
(8) Commercial swimming pools: One parking space for each
one hundred twenty-five square feet or fraction thereof of pool
area.
(9) Commercial skating rinks: One parking space for each
one hundred twenty-five square feet or fraction thereof of skating
rink area.
(e) Industrial.
(1) Industrial establishments, including warehouses, research
or testing laboratories, dairies, bottling plants and
similar establishments: One parking space for each two employees
on the maximum working shift.
(f) Multiple dwellings. One and one-half parking spaces for
each dwelling unit within a building; provided, however, that the
city council may, upon a petition from the property owner or
developer and after consideration and recommendation by the
planning commission, reduce the required parking spaces to one
space per dwelling unit if each of the following conditions exist:
(1) The character or use of the proposed building or
buildings will make unnecessary the full provision of one and
one-half parking spaces per dwelling unit because the families or
persons who will occupy these units, due to their income level, are
unlikely to own more than one car per dwelling unit, and
(2) Adequate space is not available to provide one and one-half
parking spaces per dwelling unit without violating zoning
requirements of this Code, and
(3) Authorization of this reduction in number of off-street
parking spaces will not be a substantial detriment to adjacent
property and the character of the district will not be changed by
the granting of this reduction, and
(4) This reduction in required spaces will not unreasonably
increase the congestion of public streets or increase dangers of
fire or imperil the public safety or unreasonably diminish or
impair established property values within the surrounding areas,
or in other respect impair the health, safety, comfort, morals or
general welfare or interest of the inhabitants of the city. (Code
1959, § 20-3; 10-3-60; 9-6-61; 9-7-65; 6-5-67; 9-16-68; 2-2-70; 12-770.)
Sec. 20-4. Off-street loading spaces and parking spaces for
vehicles used in operation of business.
In addition to the off-street parking spaces required by section
20-3, there shall be provided adequate off-street space for loading
and unloading vehicles owned or leased and regularly used in the
operation of any commercial or industrial establishment. In
addition, when such vehicles are to be parked at any such
establishment when not loading or unloading, there shall be
provided adequate parking space to take care of parking the
maximum number of vehicles that may be reasonably expected to
be parked at any one time. (Code 1959, § 20-4.)
Sec. 20-5. Meaning of "adjacent area of land".
"Adjacent area of land," as used in this chapter, shall mean
any plot of land contiguous to the area of land upon which is
erected the building for which the parking spaces are required or
any plot of land any part of which is directly across a street or
alley from any part of such building area or is located not more
than seven hundred fifty feet from any building served, measured
from the nearest point along the shortest line of public access.
(Code 1959, § 20-5.)
Sec. 20-6. Spaces within buildings, in basements or on roofs.
All garage and other spaces allocated for parking of vehicles
within buildings or in basements or open spaces on
the roofs of buildings shall be considered part of the required
off-street parking facilities and may be included as such in
computing the requirements outlined in this chapter, but no
such spaces shall be required to meet the provisions of this
chapter respecting design or traffic arrangements. (Code
1959, § 20-6.)
Sec. 20-7. Land or building used for two or more purposes.
(a) When any land or building is used for two or more
purposes, the number of parking spaces required shall be the
sum of the requirements for the various individual uses, computed
separately in accordance with this chapter. Parking
facilities for one use shall not be considered as providing the
required parking facilities for any other use.
(b) Requirements for the provision of parking facilities
with respect to two or more property uses of the same or
different types may be satisfied by the permanent allocation
of the requisite number of spaces for each use in a common
parking facility cooperatively established and operated; provided,
that the number of spaces provided shall not be less
than the sum of the individual requirements; provided
further, that the specifications in regard to location, plan,
etc., shall be complied with. (Code 1959, § 20-7.)
Sec. 20-12. Drainage; resistance to erosion.
All off-street parking facilities required under this chapter
shall be so drained as to prevent damage to abutting properties or
public streets and shall be constructed of material which will
assure a surface resistant to erosion. (Code 1959, § 20-12.)
Sec. 20-13. Aisles; entrance and exit driveways.
Aisles, entrance and exit driveways shall be built to the
following minimum specifications:
(1) Aisles with two-way traffic movement shall be not less than
twenty-two feet in width.
(2) Aisles with one-way traffic movement shall be as specified
below:
(a) Aisles serving ninety degree parking shall be not less
than twenty-two feet in width.
(b) Aisles serving sixty degree parking shall be not less than
twenty feet in width.
(c) Aisles serving forty-five degree parking shall be not less
than fifteen feet in width.
(d) Aisles serving thirty degree parking shall be not less than
twelve feet in width.
(e) Where such aisles serve parallel parking which are
located immediately adjacent to buildings they shall be not less
than sixteen feet in width. All other aisles serving parallel
parking shall be twelve feet in width or as much additional width
as may be required for access of emergency vehicles or curvilinear
streets.
(3) The location and design of entrance and exit driveways for
all lots, except those serving one-family and two-family
residences, shall be approved by the city manager to insure a safe
and convenient means of ingress and egress. (Code 1959, § 20-13;
3-6-67; 8-4-69.)
Sec. 20-14. Access to street or alley; dimensions of spaces;
setback.
In providing off-street automobile or vehicular parking spaces
as required by this chapter, such spaces shall have adequate
access to a street or alley and such access and spaces shall not
thereafter be reduced or encroached upon.
Except in the case of parking provided for one-family or
two-family dwellings, each required parking space shall be not
less than twenty feet in length and nine feet in width, exclusive of
driveways and aisles. Such parking spaces shall not be located
within the required front and side yard setbacks. No vehicle shall
be parked within six feet of any entrance or exit way. (Code 1959,
§ 20-14; 3-6-67.)
Sec. 20-15. Lighting.
Adequate lighting shall be provided for off-street parking
facilities used at night; provided, that lighting for one-family and
two-family dwellings shall not be required. Lighting installations
shall be arranged so as to concentrate the illumination upon the
parking area and prevent glare from falling onto the adjoining
property. (Code 1959, § 20-15.)
