It is the intent of these regulations that all buildings, structures and uses of land shall provide off-street parking and loading space in an amount sufficient to meet the needs caused by the building or use of land and that such parking and loading spaces be so oriented that they are in fact readily usable for such purpose. Because of the pedestrian orientation of the core of the central business district it is intended that parking be provided at the periphery of the core.

Effective on: 1/1/1901

Each use of land and each building or structure hereafter constructed or established, and each addition to a structure in excess of three hundred (300) square feet, except as herein provided, shall provide off-street parking and loading according to the standards set forth herein. When an addition is made to a building non-conforming as to parking or loading, a conforming amount of parking shall be supplied based upon the size of the addition.

Effective on: 1/1/1901

No addition to an existing building shall be constructed which reduces the number of spaces, area or usability of existing parking or loading space unless such building and its addition, conform with the regulations for parking and loading contained herein. Contractual agreements may be made between uses which generate parking demand at different times in such a manner that the requirements of more than one (1) use may be met by the same space, provided the parking demand for each such use involved is in fact met.

Effective on: 1/1/1901

All off-street parking and loading spaces, access and aisles shall be paved or surfaced with concrete, asphalt or other approved non-permeable surface. On areas of slopes over three percent (3%), surfacing shall be poured concrete.

Effective on: 1/1/1901

Uses listed below shall provide parking and loading in the amounts specified and at locations specified for the group in which such use falls. For any use not listed, the Board shall determine the proper requirements by classifying the proposed use among the uses specified herein so as to assure equal treatment. In making any such determination, the Board shall follow the principles set forth in the statement of purpose for the parking and loading provisions.

Effective on: 1/1/1901

For the purpose of these regulations a parking space shall be at least one hundred eighty (180) square feet in size and shall be of easily usable and convenient shape, orientation and grade. Each such space shall be readily accessible and aisles required for access to any space shall not be counted in meeting the requirements for spaces. Loading spaces shall be at least twelve (12) feet wide and sixty (60) feet long for industrial and warehouse type uses but may be twelve (12) feet wide and thirty (30) feet long for retail, service and institutional establishments. Aisles adequate to accommodate the maneuvering into position of such vehicles shall be provided accessory to such space or spaces. Specified distances from the principal use for which a parking space is provided shall be measured from the edge of the usable parking space to a normal entrance to the building or use along a convenient and unobstructed pedestrian route. Required parking space shall not be provided within a required front yard, or a side yard at a corner. Handicapped parking provisions shall be provided in compliance with Chapter 321 L of the Code of Iowa.
