All trees eight-inch caliper and over shall be identified on the site plan with notations of trees to be preserved and trees to be removed.
(2)
Trees intended to be preserved shall be noted with a unique symbol on the site plan and be protected during construction through the use of construction fencing at or beyond the dripline of the tree or trees to be preserved.
(3)
Trees to be preserved shall be considered for credit only if they are located on the developed portion of the site as determined by the planning commission. The planning commission, pursuant to site plan approval, may allow credit for such plant material preservation if it will maintain and encourage the intent of this chapter. To obtain credit consideration, the preserved trees shall be of a high quality and at least two-inch caliper.
(4)
Credit consideration for preserved trees shall be:
Table 8-3
(5)
To protect and encourage the continued health and vitality of the preserved trees, the ground within the dripline of the trees shall be maintained in the existing natural state. Storage of soils or other materials during or after construction within the tree dripline is prohibited.
(6)
If preserved trees die within three years after construction the property owner shall replace with trees required before credit was allowed. Said trees shall be replaced within 60 days of written notice from the city or within an extended time period as specified in said notice.
(7)
The minimum number of required trees shall not be reduced by more than 50 percent through the use of approved tree credits.

The standards outlined below are intended to encourage the preservation of quality and mature trees by providing credits, at planning commission approval, toward the required trees for greenbelts, buffer zones and within parking lots.
(1)
All trees eight-inch caliper and over shall be identified on the site plan with notations of trees to be preserved and trees to be removed.
(2)
Trees intended to be preserved shall be noted with a unique symbol on the site plan and be protected during construction through the use of construction fencing at or beyond the dripline of the tree or trees to be preserved.
(3)
Trees to be preserved shall be considered for credit only if they are located on the developed portion of the site as determined by the planning commission. The planning commission, pursuant to site plan approval, may allow credit for such plant material preservation if it will maintain and encourage the intent of this chapter. To obtain credit consideration, the preserved trees shall be of a high quality and at least two-inch caliper.
(4)
Credit consideration for preserved trees shall be:
Table 8-3
(5)
To protect and encourage the continued health and vitality of the preserved trees, the ground within the dripline of the trees shall be maintained in the existing natural state. Storage of soils or other materials during or after construction within the tree dripline is prohibited.
(6)
If preserved trees die within three years after construction the property owner shall replace with trees required before credit was allowed. Said trees shall be replaced within 60 days of written notice from the city or within an extended time period as specified in said notice.
(7)
The minimum number of required trees shall not be reduced by more than 50 percent through the use of approved tree credits. However, the planning commission during site plan review, may determine existing landscaping or screening intended to be preserved would provide comparable required landscaping, buffering or screening and reduce or waive landscaping or buffering requirements.
(Ord. No. 2025-01, 1-13-2025)
(a)
Installation. Landscaping shall be installed in a sound workman like manner and conform to the American Standard for Nursery Stock ANSI Z60.1. If building or paving construction is completed during a planting season, then no certificate of occupancy will be issued unless the landscaping meets the requirements herein provided. If building or paving construction is completed in an off planting season, the certificate of occupancy will be issued only after the owner provides a performance bond to ensure installation of required landscaping in the next planting season.
(b)
Material removal. Tree stakes, guy wires and tree wraps are to be removed after one year.
(c)
Maintenance. Greenbelt areas and plant materials required by this article shall be kept free from refuse and debris. To keep the buffer zone in effect, plant materials shall be maintained in a healthy growing condition, neat and orderly in appearance. If any plant material required by this chapter dies or becomes diseased, they shall be replaced within 30 days of written notice from the city or within an extended time period as specified in said notice.
(Ord. No. 2025-01, 1-13-2025)

(a)
In any case where site plan review is required and the existing building and/or parking area is being increased by at least 50 percent over the originally approved site plan or the use is being changed to a more intense use, as determined by the planning commission, the site shall be brought into 100 percent compliance with the landscape standards herein.
(b)
In any case where site plan review is required and the existing building and/or parking area is being increased by at least 25 percent over the originally approved site plan or the use is being changed to a more intense use, as determined by the planning commission, the site shall be brought into 50 percent compliance with the landscape standards herein. In situations where the increase in the existing building and/or parking area is less than 25 percent over the original site plan, the requirement of new landscaping shall be equal to two percent of compliance for every one percent of increase in building or parking footprint (example: a building or parking area increase of ten percent requires a 20 percent compliance with the landscape standards). If any development or principal use requiring a certificate of occupancy is destroyed by any means beyond 50 percent of the value of the structure (as determined by calculating twice the structure's state equalized value), the site shall be brought into full compliance with the landscape standards herein.
