A. Buffers: Buffer screening between districts or parcels and uses shall be required as set forth in section 9-3-10, "Buffers", of the city code, except as noted otherwise in this ordinance. Buffers shall be established in accordance with the following:
1. Parcel A:
a. All double frontage lots shall provide a thirty foot (30') buffer along the rear lot line. Rear building setbacks shall be measured from the buffer park. Said buffer shall be located in an outlot with maintenance the responsibility of the homeowners' association. Fencing or structures, with the exception of ground monument signs as allowed by city code shall not be located within the buffers. Landscape planting within the buffer outlots shall be in accordance with city code requirements for thirty foot (30') buffer parks. Additional landscaping may be installed at the discretion of the association; however living vegetation may not be removed without city consent. In conjunction with the approval of the preliminary plat, a landscaping plan shall be submitted and approved by the city for the buffers.
B. Lot Trees: One overstory tree per lot is required within the front yard of all residential lots within this PUD to provide for the visual softening, shading, and enhancement of streets. Lot trees shall be installed by the home builder prior to the initial occupancy of the structure on the property. Tree maintenance shall be the responsibility of the individual homeowner or the homeowners' association.
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.
Trees shall not be planted closer than five feet (5') to a sidewalk as measured from the center of the tree or shrub trunk. The planting of trees on corner lots within the area bounded by the street or alley lines of such lots and a line adjoining points along said street or alley lines twenty five feet (25') from the point of intersection of the public right of way lines shall be prohibited. This area is defined as the sight triangle. No tree shall be permitted within the sight triangle of a public street intersection. No trees shall be permitted in any public utility easement.
