Uses that are permitted in CHMC § 17.19.010 but which do not meet the minimum standards set forth in this chapter may be authorized only as a conditional use in accordance with Chapter 17.10 CHMC.

The height at any point of a building or structure, except chimneys, and small dish antennas, shall not exceed 25 feet, measured vertically thereto above the original grade. Chimneys and small dish antennas shall not extend more than five feet above any part of the building or structure. No accessory structure shall exceed 15 feet in height above original grade.

The minimum lot or tract area in the S-1 district shall not be less than 250,000 square feet with a minimum frontage of 400 feet, which frontage shall be on a public street. For irregularly shaped lots, the minimum frontage width shall be measured at the front yard setback line. The minimum lot or tract depth shall be 400 feet. If a lot is serviced by a private road or pipe stem driveway, the private road or pipe stem driveway shall not be considered or included in the square footage of a lot for determining whether the lot meets the minimum required square footage.
