Once said alternative structure is approved and becomes an eligible support structure, any subsequent modifications must meet established design guidelines. The maximum height of a tower shall be determined by the height standards of Chapter 17.12.
(ii) Communication equipment or any new structure that is integrated as an architectural feature of a structure so that the purpose of the facility for providing wireless services is not readily apparent to a casual observer or which is concealed within a building or structure so that it is architecturally indiscernible may be permitted in all zoning districts subject to building permit procedures and standards. Architecturally indiscernible shall mean that the addition or feature containing the antenna is architecturally harmonious in such aspects including but not limited to material, height, bulk, scale and design with the building or structure to which it is to be a part.
e. Additional provisions for towers.
(i) Setbacks. A tower shall be set back from all property lines on which the tower is located by the distance equal to the height of the lowest engineered break point on the proposed structure or the height of the tower.
(ii) Lights. No lights shall be permitted on a tower except such lighting that is required by state or federal law.
(iii)Height. The maximum height of a tower shall be determined by the standards of Chapter 17.12. Guy wire anchors, if used, shall be set back a minimum of five feet from all property lines.
(iv) Final Site Plans: Final site plans for a tower shall be accompanied by a certification from a qualified structural engineer that the tower has sufficient structural integrity and equipment space to accommodate multiple users shall be required at the time of applying for a building permit.
(v) Notification. Prior to the issuance of a zoning permit, and immediately after receiving an application for a new tower, the zoning administrator shall notify the district councilmember that an application for a new tower has been submitted. Such notification shall only be required when a tower is proposed within a residential district, a district permitting residential uses (excluding the MUI, MUI-A, ORI, ORI-A, CF, DTC, and SCR districts), or within one thousand feet of the zoning boundary line of a residential district or a district permitting residential uses. Such notification shall also be required when a telecommunications facility is within a Historic Overlay District or right of way abutting a Historic Overlay District. Within thirty days from the date on which the tower application was filed, the district councilmember may hold a community meeting on the proposed tower. If a meeting is held, the applicant shall attend and provide information about the tower's safety, technical necessity, visual aspects, and alternative tower sites and designs considered.
(vi) When an application to construct a new tower is received, the Department of Codes Administration shall consult with the district councilmember, and the councilmember may request that the applicant accommodate tornado sirens and their associated equipment to further the public interest, as well as equipment needed for First Net. The councilmember's request shall be submitted in writing to the applicant within fifteen business days from the date the application was submitted to the Department of Codes Administration, and the request shall be accompanied by a written statement from the Mayor's Office of Emergency Management that a siren is needed in the area where the tower is to be located and that the proposed tower site is suitable for a siren. The applicant shall make good faith efforts to comply with this request, provided that if such use materially increases the cost of the tower, requires utilization of land otherwise reserved for additional wireless carriers on the tower, or would otherwise delay the permitting of the proposed tower, the applicant shall not be required to consider such request. Because tornado sirens require additional tower space and have varying design qualities, applicants will be allowed a fifty percent increase in height over the otherwise applicable height limitation and will not be required to utilize camouflaged designs, but shall comply with all applicable landscaping standards set forth in this section. This subsection applies to tornado sirens only and is not applicable for other public safety tower uses.
5. Telecommunication facilities within public rights-of-way.
a. Support structures and above-ground transmission equipment are prohibited within the pedestrian travelway, but may be located within a grass strip/green zone or frontage zone. For substantial changes to eligible support structures or for new telecommunications use of an alternative structure, the eligible support structure or alternative structure shall be relocated outside of the pedestrian travelway and all above-ground utilities consolidated with the permit application. For eligible support structures that already have wireless telecommunications facilities on them, the structure need not be relocated unless it exceeds the zoning height limitation set in subsection 17.16.080.C.5.d., unless such structure is owned by the Metropolitan Government.
b. No new telecommunication facility support structure may be erected in the public right-of-way within 500’ of an existing telecommunication support structure. The term “new telecommunications facility support structure” as used in this subsection shall not include a relocation and/or replacement of a pole pursuant to section 17.16.080.C.5.a.
c. New telecommunication facilities or relocated telecommunication facilities pursuant to subsection 17.16.080.C.5.a. shall place all transmission equipment, excluding antennas and remote radio units, underground to the extent possible consistent with departmental regulations. To the extent transmission equipment cannot be placed underground, business justification, excluding cost, for this must be provided.
d. New telecommunication facility support structures may not be erected to a height greater than the height surrounding utility poles or street lights, whichever is greater. If no utility poles are present, the total height shall be built to a maximum height of 35’, including antennas, lightning rods or other extensions. All new proposed structures, or a stealth telecommunications support structure replacing an existing support structure or alternative structure, within the ROW shall be designed for a minimum of two PWSF providers.
e. A permit for a COW is limited to 5 days, but when circumstances reasonably warrant, the permit may be renewed.
f. Telecommunication facilities shall be constructed consistent with the design requirements of the Planning Department, and, where applicable, the Historic Zoning Commission. The design guidelines will provide greater detail, description and examples of acceptable telecommunications facilities, including visual descriptions. The requirements in this section shall be in addition to those required by Chapter 6.26 of the Metropolitan Code.
6. Recommendations and other actions from departments of the metropolitan government. Prior to the consideration of a variance for or issuance of a permit for a telecommunication facility, the following departments of the metropolitan government shall submit recommendations or approvals to the Zoning Administrator that describe compliance with all applicable design guidelines or other regulations:
a. Metropolitan Development and Housing Agency (MDHA) shall provide a recommendation within a redevelopment district and/or public rights of way abutting a redevelopment district,
