The following guidelines shall be considered in reviewing the design and implementation of landscape plans in conjunction with review of site plans and special use permits.
(A) Standards for plant materials. Materials planted in any development shall comply with the following requirements:
(1) The quality of plant material selected shall meet or exceed the guidelines in the latest edition of the American Standard of Nursery Stock published by the American Association of Nurserymen unless otherwise indicated.
(2) No artificial plants of any type shall be used to meet the requirements of this chapter in any landscape area within the parcel.
(3) Minimum sizes for plant materials at time of installation for all landscape areas shall be as follows:
(a) Deciduous trees shall be a minimum size of two and one-half inches caliper when installed. Evergreen trees shall be a minimum six feet in height when installed.
(b) Deciduous shrubs (other than dwarf varieties) shall be a minimum of 36 inches in height at time of installation if used as a perimeter screen planting, and 30 inches in height for all other installations. Dwarf varieties, evergreen shrubs, and plants normally measured by spread shall be a minimum of 24 inches in both height and spread.
(c) Ground cover shall be planted at a minimum of 12 inches on center to ensure that complete coverage can be obtained within two years after date of installation.
(d) Flower beds are encouraged and shall be mass planted in acceptable areas to create color, texture and interest.
(4) Property owners shall be responsible for maintaining all landscaping shown on the approved landscape plan throughout the life of the development. All dead plants shall be replaced with plants that meet the original requirements. The plant replacement shall be completed in the next horticulturally advisable planting season for the species being replaced after the village staff has notified the owner that replacement is necessary. Annual flower beds shall be replanted each year with flowers adapted to the village's climatic conditions.
(B) Guide for planting trees. The trees recommended in division (D) of this section have minimal maintenance requirements. However, all trees must receive a certain degree of care, especially during and immediately after planting. To protect an investment in new trees, the owner or developer should ensure that proper horticultural techniques are followed. The following recommendations are provided as a guide for tree planting based on current horticultural practice.
(1) The best times for planting are early spring and early fall. Plants planted in the summer run the risk of dehydration if not properly irrigated.
(2) Plant trees and shrubs at least three feet from the back of curb along head-in parking spaces to prevent damage from car overhangs. Mulch, lawn or planted ground cover shall be utilized in this three foot area. Aligning trees with the stripes between parking stalls will further help avoid damage.
(3) Dig tree pits at least one foot wider than the root ball.
(4) Especially in areas where construction activity has compacted the soil, the bottom of the pit should be scarified or loosened with a pick ax or shovel.
(5) After a pit is dug, observe subsurface drainage conditions. Where poor drainage exists, special provisions should be made to ensure proper drainage around the tree.
(6) Backfill should include a proper mix of soil, peat moss, and nutrients. All roots must be completely covered. Backfill should be thoroughly watered as it is placed around the roots.
(7) Plants should remain plumb and level. Newly planted trees may be supported with stakes and ties to hold it firmly in place. Remove stakes and ties after one year.
(8) Spread at least three inches of mulch over plant beds in order to retain moisture and keep down weeds. A three inch saucer should be provided to form a basin around the trunk of the tree. This saucer helps catch and retain moisture.
(9) The lower trunks of new trees may be wrapped with burlap or paper to prevent evaporation and sun scald. The wrapping should remain on the tree for a least one year.
(10) Conscientious post-planting care, especially watering, pruning and fertilizing, is a must for street and parking lot trees. Branches of new trees may be reduced by as much as one-third to prevent excessive evaporation.
(C) Guide for planting shrubs. Shrubs planted for screening purposes should be given a proper growing environment. Many of the guidelines for tree planting listed in division (B) of this section also apply to shrubs. However, because specific requirements vary considerably between shrub types, this guideline does not attempt to specify the needs of all shrubs.
(D) Lists of recommended trees, shrubs and ground cover. The following list indicates plantings which will meet the landscape requirements of the village. The lists are by no means comprehensive and are intended merely to suggest the types of flora which would be appropriate for these purposes. Plants were selected for inclusion on these lists according to four principal criteria: general suitablility for the climate and soil conditions of this area, ease of maintenance, tolerance of urban conditions, and availability from area nurseries.
