The attached outline and drawing detail the Tree Protection Plan for this site. Tree protection fencing and areas requiring direct arborist supervision have been detailed. Excavation work within the Tree Protection Zone will expect the contractor to probe for roots under the supervision of an International Society Arboriculture Certified Arborist. As roots are discovered the arborist will determine whether to cut them or work around them. All root pruning will be done to I.S.A. standards. The Builder should be prepared to modify the foundation as required to preserve significant roots. In the event that tree roots larger than 2” in diameter are found outside these areas the site arborist should be notified. The developer and general contractor are expected to notify all subcontractors of the need for tree protection and the tree protection plan for this site. Other general Tree Protection Measures are included in the attached check list. • Sincerely, .....W Kay Kinyon Certified Arborist PN0409A Tree Care & Landscapes Unlimited, Inc.

I. Before Construction: App. Non -ADD. X7 ❑ a. Identify and number the trees to be protected, verify by mapping and /or tagging and note their size in D.B.H. (Diameter at Breast Height), variety, health and structural conditions, review plans. Xi ❑ b. Check with local government agencies for tree protection ordinances. X ❑ c. Remove any low limbs that may be in the way of construction equipment, and prune as needed to adhere NAA standards. ❑ d. Leave a protective covering on the soil, i.e., existing groundcover or mulch. X ❑ e. Notify all other contractors that these trees are to be saved and protected. 121 ❑ f. Install a temporary 6' high metal no -climb fence to protect the trees and their root systems. Install tree protection sign on fence. Posts located 10' on center as a general rule. For every inch in diameter of the trunk (D.B.H.) allow up to 1 foot of radius from the trunk as the protected area. (Example: 24" D.B.H. = 24' radius of protected root system.) Ideally, we need to protect more than the drip zone. The drip zone into the trunk is the support roots that hold the tree up. The roots from that drip zone out provide nutrition, water and oxygen. Try to avoid loss of more than 30% of root on any one side. This allows some encroachment within the drip line. This should be determined on a case by case site conditions reviewed. (SEE ENCLOSED SITE PLAN) 21 ❑ g. Identify any insect or disease problems that may require treatment. a ❑ h. Engineer and design proposed structures and construction to avoid root loss. Bridge type foundations can save major roots. ❑ i. Design landscape islands and planting areas large enough to accommodate trees at maturity. a ❑ j. Plant the right tree in the right place. Avoid future conflicts with buildings and utilities. X ❑ k. Have an experienced Arborist review landscape plan to assure the right tree is planted in the right place and proposed changes don't kill retained mature trees. Jul ❑ I. Consider tree removals adjacent to trees to be saved for wind related stability concerns. Page 2 • App. Non -App. • ❑ m. Check for past and proposed grade and drainage changes, consider the effects. • ❑ n. Check trees for stability. E ❑ o. Remove all trees that would not survive the effects of change. Remove all hazardous trees. Ki ❑ p. Minimize environmental changes. II. During Construction: !$ ❑ a. Keep equipment off of the root system to avoid compaction. k§ ❑ b. Keep equipment away from structure to prevent damage to trunk and limbs. • ❑ c. Don't allow chemicals to be dumped on the ground near the tree, i.e., gasoline, diesel, paint, herbicide, cleaner, thinners, etc. kl ❑ d. Provide means of temporary irrigation if the project runs through the summer. • ❑ e. If roots or limbs are cut or damaged, have them inspected by an ISA Certified Arborist and repaired or treated according to his /her recommendations. • ❑ f. Protect the trees from excessive heat, i.e., equipment, paving and /or burning. it ❑ g. Avoid trenching through the root systems, boring under them or hand digging can save roots. El ❑ h. Contact the ISA Certified Arborist familiar with the site prior to and during any activity within the drip zone or tree protection fencing for consultation. III. After Construction: ast ❑ a. Carefully landscape the area under the tree, being careful of the roots and structure. Use plantings that will live under the same conditions as that of the tree. DE ❑ b. Provide insect and disease control, fertilization and pruning as needed or adhere to long -term protection plan if provided. ka ❑ c. Avoid direct irrigation spraying onto the trunk. The amount of irrigation needed to keep new plantings alive can often be enough to kill mature trees. • ❑ d. Do not cover existing root systems with more than 2" of soil. The more soil you add, the greater the chances of damaging the root system. El ❑ e. Provide irrigation and /or drainage to emulate pre - construction conditions. NOTE: This tree protection plan identifies construction protection measures to prevent unwarranted tree loss. The identified measures limit the amount of earth disturbance surrounding the trees, and limit the removal of the tree's root systems. Due to the variation of every project, it is unlikely all of the above identified measures can be practicably applied to each individual tree; nor is it likely each measure is necessary to retain each tree. Prior to the beginning of construction a meeting between a certified arborist and the necessary contractors will be held to determine the appropriate level of protection for each tree, in relation to what work needs to be completed in the tree's vicinity. On site supervision by a certified arborist will be determined and supplied as necessary. Page 3 i 33'-0' 51'6' 26'-7 1 V. 566 3' ALLAN EROSION CONTRO SAN.
