34-2-9 GUIDELINES FOR TREE PROTECTION: A major purpose of Section 34-2 is
to protect all existing quality site trees which are not required to be removed for
approved development and construction to occur. The following are minimum
requirements for the protection of all Protected Trees within fifty feet (50') of all
development and construction activities related, but not limited, to streets, parking
lots, building sites, driveways, and sidewalks.
(A) Prior to construction or land development, the developer or builder must
clearly mark all Protected Trees within fifty feet (50') of all public rights-

trunk at a height of four feet (4') from natural grade such that the tape is
very visible to construction workers and equipment operators.
03) Prior to construction or land development, the developer or builder shall
establish designated parking areas for the parking and maintenance of all

stockpile areas for the storage of construction supplies and materials.
After approval by the City Manager or designee, the location and
dimensions of said designated areas shall be clearly identified on
construction and site plans and at the construction site.
(C) In those situations where the Drip Line of a Protected Tree is not directly
affected by construction but construction related activities may infringe on
said drip-line, protective fencing shall be installed at minimum around the
drip-line designating a Tree Protection Zone. The fencing must be a

organic material to aid in keeping soil temperatures down and in the
retention of soil moisture.

Tree Protection or Critical Root Zone. (Appendix G).
9 19312

Protection or Critical Root Zone will require a retaining wall or tree well,
made of rock or brick, to be constructed around the Protected Tree no
closer than seventy-five percent (75%) of the distance between the trunk
and the Drip Line. The top of the retaining wall should be constructed at
the new grade. Additional measures to maintain proper oxygen and water
exchange with the Protected Tree roots may also be required. (Appendix
(H) All Protected Trees shall be provided with a permeable surface under a
minimum of seventy-five percent (75%) of the existing Drip Line of the
tree(s).

public land, as designated by the City Manager or his designee. Required Tree
Replacement will be determined as follows:

or construction site will be made to restore the original natural landscape
character of the site.
11 19312
1. Protected Trees will be replanted at a replacement ratio of one inch
(1") DBH of Replacement Tree for each one inch (1') DBH of

ratio of ten inches (10") DBH of Replacement Tree for each one
inch (1") DBH of removed tree.
3. Replacement Trees must be a minimum of three inches (3") DBH,
