ORDINANCE 2010- 008 Project sites with a depth from a thoroughfare plan road of four hundred (400) feet or less shall have a minimum buffer depth of fifteen (15) feet. Sites with a depth over four hundred (400) feet shall have a minimum buffer depth of twenty (20) feet. The required depth of the thoroughfare plan road/local road buffer on any site shall not exceed ten (10) percent of the depth of the site, measured perpendicular to the thoroughfare plan road. In such cases where the roadway buffer depth is reduced, the required amount of plant material may also be reduced on a prorated basis. (b) A four (4) -foot high visual screen is required between any project site parking area and any adjacent roadway or exclusive driveway. This visual screen may consist of a berm with shrubs planted across the top in either an offset double row or a serpentine pattern, or a four -foot vegetative screen. The visual screen must be at least four feet high above the grade of the project site parking area or adjacent roadway, whichever elevation is lower, and must be installed prior to the issuance of a certificate of occupancy (CO). In no case shall the visual screen be less than 2.5 feet above the project parking area grade. Shrubs shall be planted on twenty-four (24) -to -thirty (30) inch centers. Berms if used shall have a slope no steeper than three (3) horizontal to one vertical, with a four -foot plateau. Berm modifications may be necessary for tree preservation as determined by the community development director or his designee. To provide a less formal appearance, clustering trees along the buffer strip is encouraged and uniform spacing of trees is discouraged, except where used to emphasize a particular planting theme or development style. SECTION #11: Section 926.12(2)(d), Installation and Maintenance pruning standards, is hereby amended to read as follows: (d) Pruning techniques that are unhealthy for or produce an unnatural appearance to of a tree or native palm are prohibited. Such prohibited techniques include excessive topping, over - lifting, hat -racking,, lolly -popping, and excessive removal of green fronds and inflorescences, among others. Topping of trees is prohibited except where necessary to mitigate conflicts with powerlines or other structures and performed to the minimum extent necessary to provide adequate mitigation. 1 Standards for acceptable pruning practices. The following pruning standards are intended to ensure avoidance of prohibited pruning techniques and to promote strong, health, and attractive trees. a Crown thinning Crown thinning may be used as a method of pruning to increase light penetration and air movement through the crown of a tree. Crown thinning shall consist of selective removal of branches that: • Favors (retains) branches with strong, U-shaped angles of attachment. • Removes branches with weak, V-shaped angles of attachment and/or included (ingrown) bark.
