This plan is designed to specify the necessary tree protection methods and procedures required to minimize construction stress on the trees that will be impacted by this project, as well as to identify existing hczardous trees that are recommended for removal, It is my opinion that if the tree conservation plan is followed and implemented the remaining trees on the site should not suffer irreparable damage, I have worked on many tower sites in the past and faund them to be a "low impact° construction process. The trees on this site (primarily Virginia and Shortleaf Pine) should be able to survive the stress if taken care of along the way, Sincerely, � ---- - �L�W Mic el Abbott ISA Certified Arborist MS in Forestry 'I III I A kAkl I -F -1 -1 -I kFF.

Morin BC Architects Engineers, PLC 5659 Columbia Pike, Suite 101 Falls Church, VA 22041 -2868 Dear Mr. Morin, Enclo sed you will find a Tree Conservation Plan for the proposed project entitled "CV 333A Springdale Drive." The plan is designed to specify the necessary tree protection methods and procedures required to minimize construction stress on the trees that will be impacted by this project, as well as to identify existing hazardous trees that are recommended for removal. Trees are recommended for removal when they are located within 1,5 times their height from the proposed structure and meet the following criteria: The tree is dead or in irreversible decline. The tree is on unreasonable risk due to a structural defect that cannot be reduced to a reasonable risk level through the implementation of standard arboricultural practices. This site is primarily populated by Pine and the only unique need here is treatment to prevent an attack of Southern Pine Beetle. Tree # 218 (a pine) is leaning and is a hazard. This tree should be removed. I have developed a table that describes each tree species, specific recommendations for their care, and any relative comments. The required tree protection procedures are broken up into 3 categories, pre - construction, during construction, and post- construction.

The zone will be defined as an area that is 9 inches times the diameter at breast height (DBH) away from any tree to be protected. ra A 4 foot high, orange, UV- resistant, high - tensile strength, barricade fabric fence shall be installed to define the Tree Protection Zone and limit access. During Construction o The Tree Protection Zone will be inspected and maintained on a daily basis. a Trees shall be inspected on a regular basis by a certified Arborist to evaluate for construction trauma, as well as for secondary pest and disease concerns, and irrigation needs. c No construction equipment, supplies or debris will be allowed in the Tree Protection Zone. Trenching or excavation within the Tree Protection Zone will not be allowed without consultation with certified Arborist and will require specialized equipment to perform proper root pruning. o Root pruning will be performed under the supervision of a certified Arborist and will be performed in such a manner, and with equipment designed to cut through roots cleanly, so as not to tear roots. If roots greater than 2 inches in diameter are encountered during root pruning, they shall be traced back towards the tree using an air -spade and pruned by hand at a point specified by the Arbonst. o Grade changes around trees shall be avoided. Excess soil and debris must be removed from site. • . - '0 "0/' s �,i ,Post -construction Tree protection fencing shall be removed. The following tree group shall be treated to reduce risk of damage due to Southern Pine Beetle. All Pines The following trees shall be fertilized based on specific needs as determined by soil analysis. Fertilization should include Mycorrhizae inoculation for mature trees, and should be applied using the sub - surface soil injection method. Trees # 208 -238 Trees that have been affected by construction shall be pruned to remove any dead or damaged limbs. Any bark wounds shall be traced to promote wound closure. Trees shall be inspected during the growing season following construction by a certified Arborist to evaluate for construction trauma, as well as for secondary pest and disease concerns, and irrigation needs. The inspection period will extend for up to 18 rnonths following completion of construction-
