Section 20M.  Conditional Uses Permitted.  A use permitted as conditional in an R-6 zone is permitted as a conditional use in an R-4.5 zone.

(6)          In a newly platted or replatted subdivision of eight lots or more, front yards shall be varied, and side yards may be varied, as specified in the Lot Dimension and Setback Variation Requirements adopted under Subdivision Ordinance Article VII.

Section 20Q.  Height of Building.  In an R-4.5 zone, buildings shall not exceed a height of 35 feet or two-and-a-half stories, whichever is less.

Section 20R.  Lot Coverage.  In an R-4.5 zone, buildings shall not occupy more than 55 percent of the area of an interior lot nor 60 percent of a corner lot. 

Section 20S.  Sidewalk and Street Tree Standards.  In an R-4.5 zone, in a newly platted or replatted subdivision, property line sidewalks shall be installed with a minimum 4.5 foot wide planting strip between the curb and the sidewalk.  Street trees shall be planted in the planting strip, concurrent with home construction, at two trees per lot for lots with fifty feet of frontage or greater and one tree per lot for lots with less than fifty feet of frontage.  Where site conditions are favorable, the City encourages the provision of stormwater management facilities within the planting strip and other low impact development (LID) techniques and practices as described in Section 131B Habitat Friendly Development Practices.  Street trees shall be planted in compliance with City standards.
