Vehicular and pedestrian safety factors from the following list must be incorporated into all landscape designs: 
6.1   The positioning, location, and type of plant material, screening, and other landscape elements should allow for natural surveillance of the outdoor spaces from within buildings, from outdoor locations on-, and from adjacent buildings, , and rights-of-way.
6.2   Landscaping and screening should complement efforts to define public, semipublic, and private spaces.
6.3   Entrances to and exits from buildings or open spaces around buildings, including pedestrian walkways, should be open and in view of the surrounding neighboring or adjacent in order to reduce opportunities for crime.
6.4   Curbs, sidewalks, and landscaped trails should be used to define public, semipublic, and private areas.
6.5   Property owner/occupant areas of influence should be defined through the use of design elements, such as walls, fences, changes in or , lights, color, or change in paving texture.
6.6   To allow maximum visibility and surveillance of the development, screening should be used that is no higher than required by this section unless high enough to create an effective barrier to entry.
6.7   In areas adjacent to doors and windows, applicants should select plant material of such height to retain visibility of building openings from the street or from other development (e.g., less than 30 inches or with a greater than six foot space between the ground and the canopy).
6.8   Shrubs and ground cover located within four feet of the edge of a walkway may not exceed 30 inches in height, except where other standards call for a greater height. An effort should be made to avoid a design requiring a greater height. Trees located less than 12 feet from the edge of a walkway must be trimmed to a minimum six foot canopy height. (See Figure 5-E, Pedestrian Safety Zone.)
6.9   Use of barrier plants (see Figure 5-F, Security Plant Materials) in areas adjacent to walkways is recommended with consideration for pedestrian safety in compliance with Section 5-01.8.0, Screening Safety Standards.
6.10   Unless adjacent to a pedestrian path, barrier plants must be planted below and extending at least 12 inches beyond each side of windows. Plant materials in this area may be no higher than the sill height of the window.
