The ordinance enacts Chapter 12.58 and amends Section 12.36.020 (residential use table), with eleven changes to the staff draft. The council chose a minimum lot size of 8,500 square feet, below the state's 11,000 square feet; Bangerter and Plummer preferred 6,000. It set a 16-foot maximum height measured by the city's existing method, below the 20 feet the Planning Commission recommended. Mecham objected to the 16-foot height allowance; Bangerter said the public deserved more thorough Planning Commission and council review.
