Section 420.030 General Criteria and Preferences.

[Ord. No. 444 §C, 2-15-2000]
A. 
General Criteria and Preferences. A conditional use permit shall be necessary to construct, alter or modify any antenna support structure or to mount any antenna on any building or other structure in any zoning district in the City of Greendale, unless otherwise provided in this Chapter. The general criteria and preferences for granting same and the regulations governing antenna support structures shall be as follows:
1. 
Building codes and safety standards. All antennas and antenna support structures shall meet or exceed the standards and regulations contained in applicable State and local building and electrical codes as well as the applicable standards published by the Electronics Industries Association, as amended from time to time.
2. 
Regulatory compliance. All antennas and antenna support structures shall meet or exceed current standards and regulations of the FAA, FCC and any other Federal or State agency with the authority to regulate antennas and support structures. Should such standards or regulations be amended, then the owner shall bring such devices and structure into compliance with the revised standards or regulations within six (6) months of the effective date of the revision unless an earlier date is mandated by the controlling agency.
3. 
Security. All antenna support structures shall be protected from unauthorized access by appropriate security devices. A description of proposed security measures shall be provided as part of any application to install, build or modify antennas or support structures. Additional measures may be required as a condition of the issuance of any permit as deemed necessary by the Director or the Board of Alderpersons.
4. 
Lighting. Antenna support structures shall not be lighted unless required by the FAA or other Federal or State agency with authority to regulate, in which case a description of the required lighting scheme will be made a part of the application for conditional use permit.
5. 
Advertising. Unless a disguised support structure is in the form of a standard outdoor advertising structure, the placement of advertising on antenna support structures is prohibited.
6. 
Design.
a. 
Guyed towers are prohibited absent a determination by the Board of Alderpersons as provided in Sections 420.050(E)(2) or 420.050(E)(3) of this Chapter.
b. 
Antenna support structures except disguised support structures, shall maintain a galvanized steel finish or subject to the requirements of the City or the FAA, FCC or any applicable Federal or State agency, be painted a neutral color consistent with the natural or built environment of the site.
c. 
Shelters or cabinets shall have an exterior finish compatible with the natural or built environment on the site and shall also comply with such other reasonable design guidelines as may be required by the City.
d. 
Antennas attached to a building or disguised support structure shall be of a color identical to or closely compatible with the surface to which they are mounted.
e. 
Towers shall be surrounded by a landscape strip of not less than ten (10) feet in width and planted with materials which will provide a visual barrier to a minimum height of six (6) feet. Said landscape strip shall be exterior to any security fencing. In lieu of the required landscape strip, a minimum six (6) foot high decorative fence or wall may be approved by the City upon demonstration by the applicant that an equivalent degree of visual screening is achieved.
7. 
Location and setback.
a. 
No antenna support structures, excluding disguised support structures, shall be located within one-half (½) mile of another pre-existing antenna support structure, with the distance being measured from the center of the base of the existing structure to the center of the base of the proposed structure. Absent a determination by the Board of Alderpersons as provided in Sections 420.050(E)(2) or 420.050(E)(3), antenna support structures, except disguised support structures, shall not be located within five hundred (500) feet of any residential structure or any parcel of property used as a park, playground, school, library, hospital, church, historic district, landmark, cemetery or an area on the National Register of Historic Places.
b. 
The minimum setback from all adjoining property lines shall be that required for principal structures in the applicable zoning district, plus one (1) additional foot for every one (1) foot in height of the antenna support structure.
8. 
Height. Antenna support structures shall not exceed a height of seventy-two (72) feet in any of the City's zoning districts, unless a different height is authorized because of the application of Section 420.030(9)(c) or because of a determination of the Board of Alderpersons pursuant to Section 420.050(E)(2) or Section 420.050(E)(3) hereof.
9. 
Co-Use. Prior to the issuance of any conditional use permit the applicant shall:
a. 
Submit a notarized statement agreeing to make the proposed antenna support structure available for use by others, subject to reasonable technical limitations and financial terms.
b. 
Furnish an inventory of all known antenna support structures and potential building sites located within one-half (½) mile of the proposed structure site, identifying the owner of same as well as the antenna support structure's type and reference name or number, if applicable, and the street location, latitude and longitude, height, type and mounting heights of existing antennas and an assessment of available space for the placement of additional antennas, shelters and/or cabinets. The applicant shall further demonstrate that he/she has requested co-use of each existing building or antenna support structure from the owner thereof and/or shall indicate why such co-use is inappropriate or was otherwise not allowed.
c. 
Antenna support structures may be constructed or modified so as to exceed the height limitations provided in Section 420.030(8) hereof to accommodate co-use. An applicant may request an extension of twenty (20) additional feet per co-user, whether actual or anticipated, up to a limit of forty (40) additional feet. The City may also require the applicant of new construction to exceed the applicable limitation, regardless of whether a co-user is immediately available to share space with the applicant.
d. 
In the event that a conditional use permit is granted for the construction of a new antenna support structure, the applicant shall notify in writing any other known potential service providers in that area that the structure will be available for co-use. Said notices shall issue on or before the day on which the applicant submits to the City an application for building permit for the structure. The notice shall allow potential co-users thirty (30) days within which to express any interest in co-use, during which time the applicant shall not commit to a design for the structure which precludes co-use, and the City shall not issue a building permit until such time has expired.
e. 
The willful and knowing failure of an applicant to agree to co-use or to negotiate in good faith with potential co-users may be cause for either the denial of a pending application, the revocation of an existing conditional use permit, and/or the withholding of future similar permits to the applicant.
10. 
Site selection.
a. 
Sites in the City's non-residential districts are preferred. Sites in any residential district in the City are prohibited absent a determination of necessity by the Board of Alderpersons pursuant to Section 420.050(E)(3). Within any zoning district, existing antenna support structures and buildings are preferred, as are locations where the existing topography, vegetation, buildings or other structures provide the greatest amount of screening.
b. 
Antennas and antenna support structures should be architecturally and visually (color, bulk, size) compatible with surrounding existing buildings, structures, vegetation, and/or uses in the area or those likely to exist under the regulations of the underlying zoning district.
c. 
Antennas and antenna support structures should be located to minimize any adverse effect they may have on neighboring property values.
d. 
Antennas and antenna support structures should be located to avoid a dominant silhouette on ridge lines, and preservation of view corridors of surrounding residential developments should be considered.
11. 
Building mounted antennas.
a. 
Antennas mounted on buildings should be made to appear as unobtrusive as possible. Such antennas should be located as far away as feasible from the edge of the building and should be painted a color consistent with the natural or built environment of the site.
b. 
Such antennas generally shall not protrude more than twenty (20) feet from the top of the structure absent either:
(1) 
If the zoning district's height requirements are not violated, a finding by the director that the proposed antenna poses no detrimental effect;
(2) 
If the zoning district's height requirements are violated, a determination by the Board of Alderpersons as provided in Section 420.050(E)(2) or Section 420.050(E)(3).
12. 
Miscellaneous.
a. 
If a guyed tower is authorized by the Board of Alderpersons pursuant to Sections 420.050(E)(2) or 420.050(E)(3), its ground anchors shall be located on the same parcel as the tower and such anchors shall meet the setbacks prescribed in Section 420.030(7) hereof.
b. 
Vehicle or outdoor storage on the site of any antenna support structure is prohibited.
c. 
On-site parking for periodic maintenance and service shall be provided at all locations of antenna support structures.
d. 
Prior to the issuance of any conditional use permit the applicant shall demonstrate how the proposed site fits into the applicant's overall telecommunications network in the St. Louis County area.
e. 
Any antenna support structure no longer used for its original communications purpose shall be removed at the owner's expense. The owner and applicable co-users shall provide the City with a copy of any notice to the FCC of intent to cease operations and shall have ninety (90) days from the date of ceasing operations to remove the antenna support structure and any related facilities. In the case of co-use, this provision shall not become effective until all users cease operations. Any antenna support structure not in use for a period of ninety (90) days shall be deemed a public nuisance and may be removed by the City at the owner's expense.
f. 
Prior to the issuance of an administrative or conditional use permit the City may require indemnification and bonding as the City deems appropriate.

Section 420.050 Conditional Use Permit.

[Ord. No. 444 §E, 2-15-2000]
A. 
Generally. Applications for conditional use permits shall be filed, processed, reviewed and decided in the manner and time frame established for appeals to the Board of Adjustment as set out in Chapter 405, Art. V, Sections 405.130 et seq, except as may be supplemented by this Section and except that all hearings shall be conducted by the Board of Alderpersons with the Mayor presiding.
B. 
Applications. In addition to all other filing requirements, the application shall include such information as is required or may otherwise be responsive to the criteria and preferences established in Section 420.030 hereof.
C. 
Public Hearing. The public hearing required by Chapter 405, Art. V, Sections 405.130 et seq, shall be recorded and all documentary evidence of any kind submitted in support of or against the application shall be identified and labeled by the City Clerk and made a part of the public record. The Board of Alderpersons may exercise its discretion to continue the public hearing for the purpose of accepting additional oral or documentary evidence into the record for consideration.
D. 
Findings Required. In addition to any other considerations required by this Chapter, before issuing a conditional use permit for any antenna support structure the Board of Alderpersons shall consider and determine the following based upon the evidence submitted:
1. 
Whether the application and proposed antenna support structure or other proposal meets the general criteria and preferences of Section 420.030 of this Chapter.
2. 
Whether existing antenna support structures or buildings are located within the geographic network area necessary to meet the applicant's system engineering requirements.
3. 
Whether such existing antenna support structures or buildings are of sufficient height to meet system engineering requirements.
4. 
Whether such existing antenna support structures or buildings have sufficient structural strength to support the applicant's proposed antenna(s).
5. 
Whether such existing antenna support structures or buildings could be altered or modified to meet system engineering requirements or to support the applicant's proposed antenna(s).
6. 
Whether the proposed antenna would experience or cause signal interference with antennas on existing antenna support structures or buildings.
7. 
Whether the fees, costs, or other contractual terms required by an owner to lease, modify or otherwise provide the co-use on an existing and suitable antenna support structure or building are reasonable. Costs exceeding that of a new antenna support structure are presumed unreasonable.
8. 
Whether there are other limiting conditions that render existing antenna support structures or buildings within the applicant's required geographic area unsuitable.
E. 
Determination.
1. 
If the Board of Alderpersons determines that, in light of the considerations noted in Section 420.050(D), an application meets the criteria and preferences established in Section 420.030 hereof and otherwise is in accordance with this Chapter, the Board shall grant a conditional use permit, subject to whatever conditions the Board deems appropriate.
2. 
The Board may determine that although an application does not meet the strict requirements of the criteria and preferences established in Section 420.030, the general purpose and intent of said criteria and preferences are not offended because of the particular circumstances presented. If such a determination is made, the Board may vary the application of the criteria and preferences and grant a conditional use permit, subject to whatever conditions the Board deems appropriate.
3. 
The Board may determine that in light of the consideration noted in Section 420.050(D), the City's prescribed criteria and preferences effectively would preclude the applicant's reception and/or transmission of signals and that the applicant's proposed location and height are a matter of absolute engineering and economic necessity in order to ensure the completion of the applicant's network. If such a determination is made, the Board may grant a conditional use permit, subject to whatever conditions the Board deems appropriate.
4. 
Any decision by the Board of Alderpersons to deny a conditional use permit shall be in writing, based upon the evidence adduced, and shall make specific findings of fact consistent with the criteria, preferences and considerations established herein.
F. 
Appeal. Appeals from the Board's denial of a conditional use permit shall be taken to the Circuit Court of St. Louis County or to any court or agency allowed by Federal law, specifically the Telecommunications Act of 1996.
