(A) (1) A tree inventory plan shall be submitted in conjunction with all subdivision plans for a subdivision contained in this section. The tree inventory plan shall be submitted with the preliminary plat as required by the subdivision regulations.
(2) The tree inventory plan shall delineate the buildable area of a proposed subdivision lot. The Planning and Zoning Commission may permit the removal of a tree outside the buildable area of a subdivision lot with the advise of the Tree Commission provided the removal of the trees is reasonably required to develop the subdivision in compliance with this chapter.
(B) (1) All trees to be saved outside of the buildable area of a subdivision shall be conspicuously designated with suitable protective tree barriers as designated herein or as otherwise approved by the Zoning Administrator. Approved tree protective barriers shall be installed along the outermost dripline around the tree protection zone. The use of tree protection zones is encouraged rather than the protection of individual (non-specimen) trees that may be scattered throughout a development site.
(2) The layout of subdivision improvements, utilities, driveways, and the like should accommodate the required tree protection zones. Whenever practical, public improvements utilities, or driveways should be placed along the corridors between tree protective zones installation of same shall occur by way of tunneling rather than trenching.
(3) Construction site activities including, but not limited to material storage, parking, or concrete washout shall not encroach into any tree protection zone without the prior approval of the Zoning Administrator. Any tree irreparably damaged or killed within a tree protection zone as a result of construction activity shall be removed and replaced at a rate of two trees for every tree irreparably damaged or killed.
(4) Protective tree barriers shall be installed to a minimum height of four feet above ground level around the outermost dripline of the tree protection zone. Tree protection zones shall be delineated with typical temporary construction fencing or continuous rope or flagging. In either case, the tree protection barrier shall be accompanied by "Tree Savage Area" signage to be placed around the tree zone not more than every twenty (20) feet.
(C) (1) A tree planting zone shall also be submitted in conjunction with the subdivision plan submission. One tree shall be planted on each lot for every five thousand (5,000) square feet of lot area or fraction thereof. The trees required to be planted on each lot may be planted on the lot or on the public right-of-way in front of each lot. Any tree planted relative to the requirements contained herein shall not be less than three inches in diameter when planted.
(2) The tree planting plan shall indicate the total number and species of trees to be planted on each lot along with the intended location of same. The exact location of the trees and species shall be approved by the Planning and Zoning Commission, with the advice of the Tree Commission, as part of the final plat review process. Whenever the owner/developer can demonstrate to the Planning and Zoning absolute inability to plant the required number of trees, as many trees as possible shall be planted on the site. The difference of those trees required to be planted and those trees planted shall be donated to the city for use elsewhere in the city on public property. A reduction credit of one tree or more shall be granted to an owner/developer when wither of the following exists.
(a) For every tree saved within the buildable area of a lot eight (8) inches or more in diameter.
(b) For every two (2) trees saved within the buildable area of a lot four (4) to eight (8) inches in diameter.
