• ii. Within any building located on the same parcel as the building or structure on which the antenna is mounted; or

iii. On the ground and outside of any required setback or vehicle maneuvering area on the same parcel as the building or structure on which the antenna is mounted.

e. An equipment cabinet located on a building roof shall conform to the requirements for roof-mounted mechanical equipment in chapter 17.600. (Ord. 2025-0007 § 23; Ord. 2019-006 § 6; Ord. 2013-0020 § 1; Ord. 20130007 § 1)

A panel antenna, or a satellite dish not exceeding 26 inches in diameter, mounted on an active high voltage electrical transmission tower is permitted subject to staff-level site plan and design review, and shall conform to the following development standards:

• A. The panel antenna or dish shall not exceed the height of the tower by more than 12 feet.

• B. The panel antenna or dish and all brackets and cables shall be painted to match the structure at the point of attachment.

• C. The equipment cabinet, if any, is located in one of the following locations:

1. At the base of the tower on which the antenna is mounted;

2. Within any building located on the same parcel as the tower on which the antenna is mounted; or

3. On the ground and outside of any required setback or vehicle maneuvering area on the same parcel as the tower on which the antenna is mounted. (Ord. 2025-0007 § 24; Ord. 2013-0020 § 1; Ord. 2013-0007 § 1)

A. Telecommunications tower on residentially zoned lots. A telecommunication tower is prohibited on a residentially zoned lot unless either of the following applies:

1. The residentially zoned lot is developed and used for nonresidential purposes; or

2. The residentially zoned lot is owned by a governmental entity.

• B. New telecommunications towers.

1. Conditional use permit required. A new telecommunications tower requires approval of either a commissionlevel or director-level conditional use permit, as follows:

a. Director-level-Replacement monopole. A director-level site plan and design review is required for a new monopole that replaces an existing monopole, does not exceed the height of the existing pole or the maximum height limit in the zone where it is located, and is located in the same or proximate location as the monopole being replaced.

b. Commission-level. A commission-level conditional use permit is required for a new telecommunications tower that is not subject to director-level review.

2. Site plan and design review. A new telecommunications tower is subject to site plan and design review approval at the same level as the conditional use permit.
