• • 1 Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010 Page 9 e. The City may allow flexibility in landscape requirements if there are conflicts with solar power, wind power, water harvesting, food production or other innovative measures proposed for the site. f. The landscape plan shall be compared to all applicable CPTED (Crime Prevention Through Environmental Design) standards and reviewed by the police department. g. Trees and shrubs shall not be planted in the right of way without City authorization. 10. Landscaping Guidelines and Technical Requirements: The purpose of the guidelines and technical requirements is to encourage plant longevity, minimize maintenance, and mitigate conflicts with other site features. An initial investment in high quality materials, careful design and planning, and proper construction techniques can result in plant longevity and long term maintenance cost reduction. a. Species Selection: Appropriate species selection is critical to maximize the benefits of plant materials. Healthy, long lived plants well suited to a site will reduce maintenance and replacement costs, while providing the most aesthetic and environmental gain. Native species in the built environment will supplement and connect the existing natural areas. Diversity is also important for an overall healthy and balanced landscape that is less susceptible to pests and disease. 1) The City shall maintain a list of approved species. The list is based on Lino Lakes area natural vegetative cover and includes additional hardy, non - invasive species. Approved species are classified by size. For each site, plants shall be selected based on mature size and adaptability to site conditions, such as microclimate, salt, pollution and other factors. The list of approved species is not exhaustive. Applicants requesting to plant a species not on the list shall submit species name, height, width, form, hardiness zone, and other relevant information. The City shall classify new species based on tree size standards. For large projects the City may require applicants to comply with the following requirements: i. Species diversity ii. A minimum percentage of native species iii. A minimum percentage of large trees iv. A minimum percentage of evergreen trees. 2) The City shall maintain a list of prohibited species. This list includes species that are invasive or have other negative characteristics that may lead to ecological damage. 3) Exposed soil is not allowed. All areas not covered by a structure or hardscape shall be planted and mulched in accordance with the following: i. In areas with low pedestrian traffic, the use of low maintenance turf, typically fescue blends, is encouraged. In areas of high pedestrian traffic, the use of turf mixes with a higher percentage of rye grass is encouraged. ii. Turf in areas near roads and parking lots shall be salt tolerant. • iii. Groundcovers shall be turf, perennials, annuals, small grasses, or low spreading shrubs. Type of groundcover should be determined by site conditions and
