A. Maximum height. The maximum height in the UG Environment is 35 feet, except as modified in subsections 23.60A.406.B through 23.60A.406.D. B. Height exceptions for water-dependent uses. The following height exceptions apply to water-dependent uses in the UG Environment: 1. Cranes, mobile conveyers, light standards and similar equipment necessary for the function of water-dependent uses or the servicing of vessels may extend above the maximum height limit. 2. Structures accessory to a water-dependent or water-related use, including but not limited to accessory office, accessory warehouse, and accessory manufacturing facilities, may be authorized up to 55 feet in the Ballard/Interbay North Industrial and Manufacturing Center by the Director if: a. The accessory structure requires additional height because of its intended use; b. Granting additional height for the accessory structure would result in a significant amount of additional usable area for the principal water-dependent use, water-related use and/or additional area for ecological restoration and enhancement; c. Not more than 20 percent of the lot area is covered by portions of the structure that exceed the maximum height established in subsection 23.60A.406.A; d. The remaining 80 percent of the lot is preserved through a covenant for water-dependent and water-related uses if uses that are not water-dependent or water-related occupy the structure; and e. The views of the shoreline of a substantial number from residences on areas within or adjoining the Shoreline District would not be obstructed by the increased height. C. Rooftop features 1. Radio and television receiving antennas, flagpoles, smokestacks, chimneys and religious symbols for religious institutions are exempt from height controls of this Chapter 23.60A provided: a. The features are no closer to any adjoining lot line than 50 percent of their height above existing grade; or b. If attached to the roof, the feature is no closer to any adjoining lot line than 50 percent of its height above the roof portion where attached; and c. The width of the feature does not obstruct the view of the shoreline from a substantial number of residences on areas within or adjoining the Shoreline District. 2. Clerestories, communication and accessory communication devices, firewalls, green roofs, greenhouses, mechanical equipment, monitors, open railings, parapets, planters, skylights and solar collectors may extend 4 feet above the maximum height limit, except where the width of such features obstructs the view of the shoreline from a substantial number of residences within or adjoining the Shoreline District, in which case the Director may reduce the height allowed. 3. Stair and elevator penthouses and mechanical equipment may extend 10 feet above the maximum height if: a. The combined total coverage of all features does not exceed 20 percent of the roof area or 25 percent of the roof area if the total includes screened mechanical equipment; b. Allowed in the underlying zone or special district; and c. The width of such features does not obstruct the view of the shoreline from a substantial number of residences on areas within or adjoining the Shoreline District, in which case the Director may reduce the height allowed. 4. Structures may extend 18 inches above the maximum height limit if the proposed roof insulation exceeds the energy code requirements in effect when the structure is constructed. D. Bridges. Bridges may exceed the maximum height limit. (Ord. 124105 , § 3, 2013.)
