2. Zoning Map. The boundaries of the districts listed in subsection 1 are indicated upon the official zoning map of the City, which map is made a part of this Zoning Ordinance by reference to it in this section. The official zoning map and all the notations, references and other matters shown thereon shall be as much a part of this Zoning Ordinance as if the notations, references, and other matters set forth by said map were all fully described in this section.

3. Changes; Ordinance Required. Changes in the district boundaries or other matters portrayed in the official zoning map shall be made by ordinance which shall identify the affected property by legal description, the zoning district in which it then lies, and the new district to be established for said property. The Clerk shall attach a certified copy of the amending ordinance to the official zoning map.1

See EDITOR'S NOTE at the end of this chapter for ordinances amending the zoning map.
4. Adoption of New Zoning Map. The Council may from time to time adopt a new official zoning map, which shall supersede the prior official zoning map, in the event that the official map becomes damaged or destroyed, or for purposes of clarity due to a number of boundary changes, or to correct drafting errors or omissions; provided, however, any such adoption shall not have the effect of amending the original zoning ordinance or any subsequent amendment thereof.
5. Boundaries. Where uncertainty exists as to the boundaries of districts as shown on the official zoning map, the following rules shall apply:
A. Boundaries indicated as approximately following the centerlines of streets, highways, alleys or other public rights-of-way shall be construed to follow such centerlines.
B. Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.
C. Boundaries indicated as approximately following City limits shall be construed as following City limits.
D. Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks.
E. Boundaries indicated as following shorelines shall be construed to follow such shorelines and, in the event of change in the shoreline, shall be construed as following a platted lot line or for unplatted property as moving with the actual shoreline.
F. Boundaries not capable of being determined in the previous paragraphs shall be as dimensioned on the official zoning maps or, if not dimensioned, shall be determined by the scale shown on the map.
1. Purpose and Application. It is the intent and purpose of this section to establish a procedure which will enable the City to review certain proposed improvements to property within specified zoning districts of the City to insure compliance with all applicable zoning, subdivision, and building regulations. Site plans in conformance with this section, with the exception of site plans for one-family and two-family dwellings and their associated accessory buildings (See Section 197.03), shall be required whenever any person proposes to place any building, structure or hard surfacing for which a building permit is required under any other section of this code, on any tract or parcel of land.
2. Site Plan Approval Prerequisite to Building Permit and Certificate of Occupancy and Use Issuance. No building permit shall be issued for the construction of any structure or hard surfacing that is subject to the provisions of this section and/or Chapter 156 until a site plan has been submitted covering the land upon which such structure or hard surfacing is to be located, and further, approved for such development in accordance with this section and/or Chapter 156. No certificate of occupancy and use shall be issued for such structure or hard surfacing until all terms and conditions of the approved site plan have been satisfactorily completed or provided for.
3. Design Standards. The standards of design provided in this section are intended to establish criteria for those items that affect the physical aspect of Ankeny’s environment. These criteria are not intended to restrict design; however, they are intended to create a focus on development that maintains a satisfactory function and appearance within the City. It is the intent of these regulations to maintain or enhance neighborhood character, preserve values, and promote the public health, safety, and general welfare.
A. Site Development.
(1) The orientation, alignment, spacing and placement of a building driveway, parking area and/or service area on the site shall be compatible with and complimentary to buildings and sites in the neighboring area.
(2) The site shall be planned to be compatible with the streetscape that is prevalent in the area.
(3) The site shall provide for adequate parking and circulation for vehicles, bicycles, and pedestrians. This includes safe bicycle and pedestrian movement from public walks to the building and from parking areas to the building.

Studies of the traffic impact shall be provided if deemed necessary by the Department Director.
(5) Parking areas shall be treated with decorative elements, building wall extensions, plantings, berms, or other means so as to reduce their impact on public ways and adjoining properties.

For the purpose of this section, “actual construction” means that a building permit has been issued and the permanent placement of construction materials has started and is proceeding without undue delay. Preparation of plans, securing financial arrangements, letting of contracts, grading of property, or stockpiling of materials on the site shall not constitute actual construction.
10. Site Plan Enforcement. Failure to comply with and maintain the approved site plan, unless another site plan has been submitted in accordance with this section, shall be considered a violation of the Zoning Ordinance.
11. Site Plan Amendment. Any approved site plan may be amended in accordance with the standards and procedures established herein, including payment of fees; provided, the Department Director may waive such procedures for those minor changes listed in this section. Such minor changes shall not be made unless the prior written approval for such changes is obtained from the Department Director. No fees shall be required for such minor changes as follows:
A. Moving building walls within the confines of the smallest rectangle that would have enclosed each original approved building; relocation of building entrances or exits, shortening of building canopies;
B. Changing to a more restrictive commercial or industrial use, provided there is no reduction in the amount of off-street parking as originally approved; this does not apply to residential uses;
C. Changing angle of parking or aisle, provided there is no reduction in the amount of off-street parking as originally approved;
D. Substituting plant species, provided a nursery or landscape architect certifies the substituted species is similar in nature and screening effect;
E. Changing type and design of exterior lighting fixtures, provided a certified engineer or architect certifies there will be no change in the intensity of light at the property boundary;
F. Increasing peripheral yards.
12. Applicability to Existing Development. The requirements of this section do not apply to the placement of any structure for which building permits have been issued as of the date of the adoption of the ordinance codified in this section; provided, if such building permit shall expire, then a new building permit shall not be issued until the requirements of this section have been met; and provided further, if an existing structure is to be reconstructed, enlarged, expanded or otherwise increased in an amount equal to or greater than the expansions listed below, then the provisions of this section still apply:
A. In the case of building uses twenty-five percent or greater of its existing ground coverage and/or total floor space;
B. In the case of non-building uses or non-building portion of uses, twenty-five percent or greater of the existing non-building area of the site development.
