1. Minimum Plant Size: New plant materials shall meet the minimum plant size requirements contained in Table 20-C.
| Plant Material Type | Planting in Bufferyard abutting Vacant Lands | All other Plantings |

2. Berms- Undulating earthen berms not exceeding six (6) feet in height, as measured from average grade, and 3:1 slope may be permitted within a required bufferyard. Credit of up to 25 percent may be received against the required plantings through the use of berms three (3) feet in height or greater.
3. Use- A bufferyard may be used for passive recreation; it may contain pedestrian or bicycle pathways, provided that:
a. No plant material is eliminated;
b. The total bufferyard (width and length) is maintained; and
c. All other requirements of this Ordinance are met.
4. Stormwater Retention/Detention Facilities in Bufferyards - The Planning Director shall be authorized to allow stormwater retention/detention facilities to encroach into bufferyards a maximum of 30 percent of the bufferyard width, where it can be demonstrated that all planting requirements are met and the visual screen provided by the bufferyard will be fully achieved.
5. Location - All plantings for a bufferyard shall be planted within the required bufferyard.
6. Existing Plant Materials - Existing plant materials which satisfy the minimum size requirements set forth in Section 20.05(A) above and all other requirements or specifications of this Chapter shall be credited toward satisfying the bufferyard requirements of the proposed use.
7. Maintenance of Plant Materials- All plant materials in bufferyards shall be maintained in a good condition so as to present a healthy, near and orderly appearance. The owner, tenant of their agent shall insure that:
a. All plant growth in landscaped areas be controlled by pruning, trimming, or other suitable methods so that plant materials do not interfere with public utilities, restrict pedestrian or vehicular access, or other wise constitute a traffic hazard;
b. All planted areas be maintained in a relatively weed-free condition and clear of undergrowth; and
c. All plantings be fertilized and irrigated at such intervals as are necessary to promote optimum growth.
(Section 20.05 substantially changed by Ordinance #14 of 1989).
For reasons of conflicting uses, unfavorable topography or other unique or extenuating physical circumstances the Planning Commission may increase required landscape plantings in any required greenstrip or greenbelt, if in its discretion any increase is found to be necessary to reasonably achieve stated utilitarian and aesthetic objectives.
If a physical hardship exists or existing topography and vegetation are determined by the Planning Commission to provide equal or better landscape and buffering effect, the Planning Commission may approve modifications only to the planting requirements of Sections 20.04 and 20.05. The Planning Commission may require such alternate plantings and visual screens as hedges, fences, walls, and/or combination thereof which it deems necessary to ensure compliance with stated utilitarian and aesthetic objectives.
For the land area lying between the required greenstrip in the front yard of properties and the edge of pavement of a public or private street the following standards shall apply.
1. As a minimum grass or other living ground cover shall be neatly maintained and kept weed free by the owners of property abutting the public right-of-way or private easement.
2. Trees within a public right-of-way shall not be planted without the written consent of the Kent County Road Commission or the Michigan Department of Transportation.
Landscaping shall be provided for in all internal areas of parking lots so as to provide visual and climatic relief from broad expanses of pavement. Landscape features installed in fulfillment of this requirement should be designed and situated to protect lighting fixtures and fire hydrants and to define access and circulation ways.
1. When Internal Landscaping Requirements Apply- The internal landscaping requirements contained herein apply to all new development within Cascade Township. New industrial development is exempt from the requirements contained in this Section. These requirements shall also apply to expansions which would require the development to increase its parking area by at least 20 percent of the total off-street parking requirements as required in Section 19.11.
2. Internal Landscaping Area Requirements - In order to reduce the visual impacts of parking lots and to enhance their appearance to surrounding land uses, the Township requires parking lots to be internally landscaped. Based upon the number of parking spaces within a parking lot a particular land use would have to set aside some of the land area within the parking lot for landscaping. The following schedule shows the amount of land area which must be set aside for landscaping.
| a. For parking lots containing less than 50 parking spaces - 15 square feet of land area per parking space. |
| b. For parking lots containing between 51 and 99 parking spaces - 25 square feet of land area per parking space. |
| c For parking lots containing over 100 parking spaces - 30 square feet of land area per parking space. |
3. Minimum Size - The minimum size of any internal landscaped area shall be 180 square feet, with a minimum width not less than 20 feet.
4. Protection of Landscaping- Internal landscape areas shall be protected by the installation of a raised concrete curb or anchored landscape timbers around their border. The curb is intended to prevent motor vehicle infringement upon landscaped areas and to insure that the landscaping materials remain within a defined area.
5. Required Plantings- For each 180 square feet of required landscaped area one (1) canopy tree or two (2) evergreen/conifer trees.
6. Minimum Plant Size- All new plants required for internal landscaped areas shall meet the minimum size requirements setforth in Section 20.05(1) above.
(Section 24.07 was substantially revised by Ordinance #14 of 1989).
The Planning Director shall hold on file a suggested planting list to accommodate various site situations.
The following Schedule "20 A" enumerates species that are permitted but which will not be credited in required landscape areas due to their brittleness, susceptibility to disease and insects, excessive root structure, excessive litter, susceptibility to road salt damage and/or other undesirable characteristics.

For all residential uses where a lot or parcel of land has been disturbed or cleared for development, the disturbed area shall be finish graded and landscaped within the time specified below, except for driveways, walks, and required parking areas. Seeding or sodding shall be the minimum acceptable landscaping of any said lots or parcels of land. This minimum landscaping shall be installed not later than (1) one year after a Building Permit has been issued by the Building Inspector, and shall be reasonably maintained thereafter. After the period of one (1) year of occupancy, the Building Inspector may require the posting of a financial guarantee in an amount up to One Thousand Dollars ($1,000.00) to assure installation of the landscaping and may extend the one year time limit if conditions warrant.
