• 3.6. LANDSCAPING REQUIREMENTS Site Planning to Preserve Natural Assets While the network of required streets is fixed, many siting decisions remain for other streets and for buildings. Views & Vistas. Site planning shall recognize the role that street alignment and topography contribute to visual prominence. High points on the land and vistas along common routes provide unique opportunities to site important buildings, building entrances, plazas, and monuments. Doing so will add recognizable landmarks that can make the Town Center a memorable place. Grading. Site planning shall minimize gradingwhen locating streets and buildings. When areas with slopes must be graded, "landform" grading techniques shall be used and slopes exceeding 1:3 shall be avoided. Rounded forms that use concave and convex shapes help conceal cuts by presenting a more "natural" look. Varied slopes also disperse drainage flows, reducing the potential for erosion and allowing more percolation. Concentrating drainage in concave males also enhances on -site stormwater retention and minimizes the need for large detention areas off -site. If required, any retainingwalls shall not exceed 5 feet in height. Landscaped Frontages (See city landscaping pallet for accepted species) A ten foot wide landscaped buffer must be placed where parking lots abut local and surrounding streets, including alongLake Drive. However, care shall be taken to design and site the buffers such that they do not provide ambush points or obstruct views. The buffer must include at least one of the following • A low fence or wall ofbetween 24 to 36 inches high, within 3 feet of the street's sidewalk, and trees planted not more than 30 feet on- center, • A "hedgerow" of poplar, cypres3 or othcr tall el:Am-miff trees planted not more than 30 feet cri-cEntEcokribined with shrubs; • A trellis supported by posts not more than 15 feet apart on center, within 3 feet of the street's sidewalk, and trees planted not more than 30 feet on- center, or • An equivalent feature that screens views of parked cars and defines the street spatially. Along Interstate 35W frontage, there is a metal security fence. Planting to screen the security fence along 35W is encouraged. Chainlink and cyclone fences are stdctly prohibited. 35 y41:rY 43'i tj ri_ri,to r rh ricAi.NA Yi tt n .
