(1) New buildings and additions to existing buildings may not exceed a height of one-half (1/2) of the horizontal distance from any part of the building to the nearest point on (a) the outside edge of any buffer area established under Section 14.17C.040, Provo City Code, or (b) where there is no buffer, the TF zone boundary.

(2) The height limitation imposed by Subsection (1)(b) of this Section shall not apply if the private property on both sides of a zone boundary line at the point nearest the building (ignoring any right-of-way property owned by a public entity) is either part of the same parcel or is owned by the same person or entity, or affiliated entity, in which case the applicable point of measurement shall be the nearest point of any other private parcel within the R1 zone.

(3) Notwithstanding the foregoing, in no case may the height of a building exceed one hundred (100) feet.

(4) For the purposes of this Section, building height shall be measured from the average elevation of the finished lot grade at each face of the building, minus any artificial terracing or earth berming placed by the owner that goes beyond that required for backfill or foundation drainage, to the highest interior space of any habitable portion of the building, and shall not include the roof, church spires, belfries, cupolas, or domes and the like not used for human occupancy, nor to chimneys, skylights or cornices.

(5) Notwithstanding the foregoing, roof-mounted mechanical and communication equipment shall not exceed a height of twenty-five (25) feet above the one hundred (100) foot limit referenced above. All mechanical equipment and communication equipment on flat roofs shall be screened by a parapet wall, except for antennas that require unobstructed clearance. Parapet walls on buildings higher than seventy-five (75) feet must step back from the plane of the building walls a minimum of ten (10) feet. For a sloped roof, roof-mounted mechanical equipment and communication equipment must be within the roof slope and not on top of the roof slope.

(6) There shall be allowed to be constructed on at least one (1) building in the TF zone roof-mounted transmission and/or receiving antennas that are not subject to the height limitations of Subsection (5) of this Section; provided, that such building must be situated at least three hundred (300) feet away from any residentially zoned private property line within the R1 zone and is situated within five hundred (500) feet of an arterial or collector-class, public roadway.
