4. Supplements to the Official List of Plant Materials. The list of Official List of Plant Materials has been compiled using the latest research data available. Plants other than those listed may be used to fulfill minimum landscaping requirements as approved by the Zoning Administrator. To be considered for approval, a proposed plant material must be submitted for review with the following information:
A. Common name and scientific name of plant material;
B. Habitat, geographic climate range and whether plant is native to this region;
C. Growing characteristics, including evergreen or deciduous, height and spread at maturity;
D. Suitability for different landscape uses and applications;
E. Susceptibility to disease and tolerance of environment: heat, drought, pollution stress;
F. Fruit bearing characteristics which may be hazardous in pedestrian and parking areas.
5. Encouragement of Native Landscaping Materials. The use of suitable native plant materials is encouraged to fulfill landscaping requirements. Native plants, or those plants which occur naturally in this region, have shown greater adaptability to the seasonal and climate changes which occur in this region.
6. Installation Standards for Required Landscaping.
A. Basic plant materials standards shall include the following:
(1) Evergreen trees: minimum height of 6 feet;
(2) Shrubs: minimum two-gallon size container, or the equivalent height and/or spread;
(3) Groundcover shrubs: minimum spacing upon installation of 18 inches on center;
(4) Deciduous shade trees: minimum caliper (diameter) of 2 inches as measured 6 inches above the ground;
(5) Ornamental deciduous trees: minimum caliper (diameter) of 2 inches as measured 6 inches above the ground.
B. All other specifications shall conform with the American Standards for Nursery Stock, published by the American Association of Nurserymen for that type of tree or shrub at the time of installation.
C. All plant material shall be installed free of disease and in a manner that ensures the availability of sufficient soil and water to sustain healthy growth.
7. Minimum Spacing of Plant Materials.
A. Tree spacing along streets: minimum of one tree for every 50 feet of perimeter length.
B. Spacing of trees: spacing consistent with generally accepted species spread dimension at maturity defined by American Standards for Nursery Stock, or a minimum of one tree for every 50 feet, whichever is less.
C. Groundcover shrubs: minimum spacing upon installation of 18 inches on center.
D. Groundcover turf: immediate and complete coverage of area within the season.
E. Groundcover, creeping: spacing adequate to provide complete coverage in three years.
8. Supplemental Installation Requirements for Shrubs.
A. Shrubs shall be installed in a manner that promotes ease of maintenance and quality appearance.
B. All shrubs shall be installed in designed beds or naturalized settings containing a minimum of 3 inches of organic or inorganic mulch, contained by some form of edging, with an underlayment of landscape fabric.
C. Shrub installations beyond mere shrub beds, such as may contain groundcovers, native perennials or seasonal annuals, may be approved without these features at the discretion of the Zoning Administrator, upon demonstration of quality design and a maintenance contract/commitment.
