Morin 8C Architects Engineers, PLC 5659 Columbia Pike, Suite 101 Falls Church, VA 22041 -2868 bear Mr. Morin, Enclosed you will find a Tree Conservation Plan for the proposed project entitled "CV 393A Cross Roads." 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: o The tree is dead or in irreversible decline. o The tree is an unreasonable risk due to a structural defect that cannot be reduced to a reasonable risk level through the implementation of standard arboriculture) practices. Two hickory trees must be removed as they are in the footprint of the site, one maple must be removed as root damage from construction would likely kill the tree and make it a hazard, and finally a tulip poplar must be removed due to decay and risk to person and property. 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. cerel ��— — Mlc ael Abbott ISA Certified Arborist M5 in Forestry.,. 11 r.

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. o 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. o 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. o No construction equipment, supplies or debris will be allowed in the Tree Protection Zone. o 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 is ... .._ _ _. ,_: ._ _._.... -_ .�_, .. _._.._ .,..�:,..-Sc„p }';,,ndx'�x§.:re {max :,..sn».• .� .,. +G ...w -.. ..s +R: u*. «�a .x3, >#sa, rp�?�"cty ,��;.4sii,+� .. ��' =sR k- IX' f.

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 Arborist. o Grade changes around trees shall be avoided. Excess soil and debris must be removed from site. Post - construction o Tree protection fencing shall be removed. o 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 # 4 -14 o 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. o 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 months following completion of construction. _. �, tei .\n.�.� � .max.. r,.�..13aiE ^R M�bfw4i.ASt �r?.°�k.C. .. -. . -. 3u3Susi?•[r� e`a55; x >o.d _S.S.FSL ..ki: f3d ;U$�nva_E
