a.    Project is of superior design; and

b.    Project will not create impacts that are substantially different than would be created by a permitted multifamily development. Back to Table

DD-2.     See KZC 25.10.020(7). Back to Table

DD-3.     The required yard of any structure abutting a lot containing a low density use within PLA 5 must be increased one foot for each one foot that structure exceeds 20 feet above average building elevation. Back to Table

If one side of a dwelling unit is so attached and the opposite side is not, the side that is not attached must provide a minimum side yard of five feet; provided, that for PLA 5A this special regulation shall not supersede minimum yard requirements when abutting a lot containing a low density use within the PLA 5 zone. Back to Table

DD-11.    The rear yard may be reduced to zero feet if the rear of the dwelling unit is attached to a dwelling unit on an adjoining lot; provided, that for PLA 5A this special regulation shall not supersede minimum yard requirements when abutting a lot containing a low density use within the PLA 5 zone. Back to Table

DD-12.    Where the 25-foot height limitation results solely from an adjoining low density zone occupied by a school that has been allowed to increase its height to at least 30 feet, then a structure height of 30 feet above average building elevation is allowed. Back to Table
