I was stopping by this thread to read about the St. George area. Figured I'd answer the question as to the city's height restrictions.
I looked on the city of St. George website for the city building code. According to the city code, buildings in agricultural and residential zones (including single- and multi-family housing) are limited to 2 1/2 stories or 35', whichever is greater. Buildings in mixed-use developments are limited to 45', but may be built taller if approved by the planning commission and the city council. There was NO specific restriction that buildings be limited to be lower than the temple building...
Hopefully your city will eventually come around an amend its building codes to allow for taller buildings
