Article 1.5. Measurement, Exceptions & General Rules of Applicability | CHAPTER 1. ​INTRODUCTORY PROVISIONS

vii. Greenway 4. The required build-to percentage may be reduced by 30% when the area that would have been otherwise occupied by building facade is substituted with an outdoor amenity area meeting the requirements of Sec. 1.5.3. For example, a 70% primary street build-to could be reduced to a 49% primary street build-to under this provision. D. Design Alternate Findings The Planning Commission or Design Review Commission performing the quasi judicial duties of the Planning Commission (as designated by the City Council), after conducting a duly noticed quasi-judicial evidentiary hearing in accordance with Sec. 10.2.17., shall reduce the build-to requirement, if all of the following findings are satisfied: 1. The approved alternate is consistent with the intent of the build-to regulations; 2. The approved alternate does not substantially negatively alter the character defining street wall or establish a build-to pattern that is not harmonious with the existing built context; and 3. The change in percentage of building that occupies the build-to area or increased setback does not negatively impact pedestrian access, comfort or safety. Sec. 1.5.7. Height A. Building Height 1. Building height is measured from average grade to the top of the highest point of a pitched or flat roof, not including a maximum parapet wall encroachment. Building height must be met for the entire building, unless the multiple module height method is used in which case building height must be met for each module. The maximum height encroachment for a parapet wall is 4 feet for a 3-story building, with 1 additional foot of parapet wall allowed for each additional story thereafter. In no case shall a parapet encroachment be taller than 12 feet.

2. Average grade shall be determined using one of the following methods: a. Single Building Height Method i. Average grade shall be considered to be average post-development grade above sea level along the building elevation most parallel and closest to the primary street setback. b. Multiple Module Height Method i. As an alternative option to the single building height method, measurement of height for a building can be broken down into two or more building modules each with a separate average grade for the purposes of determining the height in feet and number of stories for the individual modules. ii. Average grade for each module shall be considered to be average post-development grade above sea level along the building module elevation most parallel and closest to the primary street setback.
