Buffering between districts or parcels and uses shall be required as set forth in title 9, chapters 5 and 19 of the city code, except as noted otherwise in this ordinance.
A. Landscape buffers shall be required along 88th Street on the east, E.P. True Parkway on the south and on the north side of the medium density (RM-12) designated portion of the Della Vita PUD. If, at the time of platting, single-family homes still exist to the north of the RM-12 portion of the property, a thirty foot (30') buffer shall be required along the northern boundary. The buffer park will not be required in the event the abutting property owner(s) to the north of the RM-12 portion of the property provide(s) a written covenant to waive the requirement. In addition, a buffer shall be required between the single- family, R-1 designated lots and the medium density, RM-12 designated lot(s) within the Della Vita PUD. The required buffer between the two (2) zoning districts shall be located entirely on parcel B.
B. Buffers required under the provisions of this section or elsewhere in this title shall be accomplished by any one of the following methods:
1. Sixty Foot Buffer: A landscaped and earthen bermed area of not less than sixty feet (60') in width comprised of landscape plantings consisting of the equivalent of one overstory or upright evergreen tree and three (3) shrubs for every thirty five (35) linear feet of buffer.
2. Thirty Foot Buffer: A landscaped and earthen bermed area of not less than thirty feet (30') in width comprised of landscape plantings consisting of the equivalent of one overstory or upright evergreen tree, two (2) understory trees and six (6) shrubs for every thirty five (35) linear feet of buffer.
A minimum of fifty percent (50%) of the required number of trees shall be evergreen. At the time of planting, overstory trees shall have a minimum trunk diameter of two inches (2"); understory trees shall have a minimum trunk diameter of one and one-half inches (11/2"); and evergreens shall be a minimum of six feet (6') in height. Shrub height at time of planting varies according to the anticipated mature size of the plant. In general, the taller the shrub at maturity the larger the plant size at time of planting. The location of the required landscaping (trees, shrubs, etc.) may be planted in any location within the buffer area.
C. The required thirty five foot (35') perimeter building setback for parcel B and the required landscape buffers are allowed to overlap.
D. Rear yard setbacks for single-family lots are measured from the interior boundary of the buffer.
E. Trees that will encroach into any vehicle or pedestrian use area or travel lane shall be of a variety that will accommodate pruning to allow for the minimum clearance height (14 feet over vehicle travel lanes; 8 feet over pedestrian travel lanes) without adversely affecting the overall natural shape of the variety. Maintaining trees to these clearance levels is the responsibility of the property owner.
F. Trees shall not be planted closer than five feet (5') to a sidewalk as measured from the center of the tree or shrub base.
G. No vegetation which obstructs visibility shall be located within the site triangle of intersecting streets and drives. (Ord. 2171, 10-17-2016)
