Item 3—Redlined Plan, Part 2 Figure 1: Hip, Gable, and Gambrel Roof Types Hip Roof Gable Roof Gambrel Roof The municipal code currently allows various types of building elements such as towers, cupolas, spires, chimneys, mechanical enclosures and other non-habitable building features to exceed the maximum permitted height by up to 25 feet above the otherwise- specified height limit for the district, up to a maximum of 65 feet. Such appurtenances may not cover more than 10 percent of the ground area covered by the structure, and are subject to design review approval. While many buildings in downtown Pleasanton are within the 40-foot height limit allowed in the Downtown Commercial area, there are a multitude of buildings that include architectural elements (e.g., roof projections or towers) that exceed the 40-foot height limitation. Examples of the heights of buildings in downtown Pleasanton are provided in Attachment 3 to this memo. Staff has evaluated various potential modifications to the municipal code standards for height measurement, including the following concepts: (1) measuring height to the highest point of the ridge or top of the structure (instead of to the midpoint of a sloped roof), with a certain fixed amount or allowance of additional height to accommodate sloped roofs; (Figure 2 shows the distinction between current and the alternative method of height measurement.) (2) measuring height from the lower of natural and finished grade; (3) clarifying the treatment of architectural elements and appurtenances, and certain types of freestanding appurtenant structures, as follows: a. clarifying that parapets must meet the maximum height; and b. distinguishing between building elements and building appurtenances such as towers, cupolas, spires, chimneys, and stair and equipment enclosures that would be allowed to exceed the maximum height by up to 15 feet (versus 25 feet as currently allowed); and the height of other free- standing and usually appurtenant structures (e.g., water towers, antennas, fire towers, flagpoles, monuments, etc.) which would continue to be allowed up to 25 feet above the base height limit.
