PAGEBOOK yt�c� Increases the tree height within required "compatibility" buffers when a 12' to 25' tall building is located within 50' of a property line. The proposal would increase the tree height from 10' to 12' for 2/3 of the trees used in the buffer and from 10' to 16' for 1/3 of the trees. Reason: Increased screening at time of planting needed to more effectively screen taller buildings located close to property lines, where a compatibility buffer is required. Increase the tree height within required "compatibility" buffers, when a building over 25' is proposed within 70' of a property line. The tree height would be increased from 10' to 16' for all trees within the buffer. Reason: Increased screening at time of planting needed to more effectively screen taller buildings located close to property lines, where a compatibility buffer is required. Taller trees required adjacent to taller buildings. 2. Landscape Maintenance & Replacement Prohibit trimming of mature canopy trees (after 7 years of growth) to less than a 15' diameter canopy. Reason: Excessive pruning defeats intent (definition) of mature canopy tree "volume". Establish replacement criteria for dead material. Any material replaced within 18 months of project C.O. can be planted at the original height specified in the landscape chapter. From 18 to 36 months, replacement canopy trees would need to be 16tall, understory trees 8' tall, and shrubs 30" tall. Thirty-six or more months after C.O., replacement canopy trees would need to be 18' tall, understory trees 10' tall, and shrubs 36" tall. Reason: Replacements need to be consistent with other materials that have been growing well on site. Also, ensures landscape code intent for sites to achieve mature landscaping look and mature landscaping "volume" in a reasonable timeframe. 3. Landscaping Along Roadways Requires landscaping along -a site's entire road right-of-way frontage, rather than only between parking areas and right-of-way. Reason: Provides a modified, enhanced landscaping appearance along the "public view" side of project sites, regardless of parking lot location or orientation. Increases the number of canopy trees along collector roads from 1 tree per 30 lineal feet to 1 tree per 25 lineal feet. Reason: Increases slightly the positive aesthetic effect of roadside landscaping. Increases the number of canopy trees along arterial roads from 1 tree per 30 lineal feet to 1 tree per 25 lineal feet; and adds a requirement for 1 understory tree per 25 lineal feet. Reason: Establishes a denser roadside enhancement along the heaviest traveled roads and "entry -ways" throughout the county. • Establishes the parking lot grade as the benchmark for measuring hedges that are required along roadways. Requires such hedges to be maintained at a height of 3' above parking lot grade. Reason: Relates the hedge to the area it is designed to screen; namely, the Erst 3' vertical distance above a parking lot (partially screens vehicles in parking lot). 4 September 8, 1997 M M M
