Dead. Edge of stand. Leaning over adjacent building approx. 1/3 Height away. High likelihood of failure and damage to roof, gutter & balcony. Permit Needed - Removal Removal 2 London Plane (Platanus X hispanica) [968378] 10.7" DBH. Fair. Cracking of adjacent drive aisle asphalt. Root Pruning not a viable option as target location is within 3x DBH of the tree. Tree located in Parking Lot Finger with uncorrected lean over drive aisle & parking. Permit Needed - Removal NO PARKING SIGNS REQUIRED Removal 3 Lodgepole Pine (Pinus contorta subsp. murrayana) [967479] 17.3" DBH. Fair. Tree at edge of Wildland-Urban interface. Tree crowded into adjacent building by surrounding native vegetation. 1 of 2 co-dominant leaders within 3" of roofline. Location and proximity to adjacent building constitutes a substantial fire hazard. Permit Needed - Removal Removal 4 European White Birch (Betula pendula) [1001026163] 11.4" DBH. Poor. Tree declining from reduced availability of water. Located on landscaped slope with little to no mulch or vegetative cover. Leaning toward & within falling distance of adjacent building. 5’ from building. 50% of canopy is dead. NO PARKING SIGNS REQUIRED Crown Clean 5 European White Birch (Betula pendula) [967526] 10" DBH. Poor. Dieback in upper crown. Leader already failed. Several other secondary & tertiary limbs dying. NO PARKING SIGNS REQUIRED Crown Clean Project Management Services Description Quantity Amount Subtotal Fuel Surcharge (5%) Environmental Waste Fees* (Waived if property chooses to keep onsite) Created:2022-11-18 15:40:52 Proposal ID:250464 Address:2223 Benson Rd S, Renton, WA 98055 PROPOSAL FOR ECHO MOUNTAIN 2022 / Recommend Removals / Echo Mountain / Avenue 5 Removal Permit / Contract Fees (price subject to change based on city approval) Subtotal: Taxes: Definition of Treatments: Crown Clean - Removal of dead, dying, diseased, crossed, and weakly attached limbs to promote trees health, safety, and beauty. 2" in diameter or greater OR appropriate diameter and amount of wood removed is to be determined by Arborist or Representative. Includes any necessary clearance away from buildings and/or structures. Will not prune within 10 ft of overhead power lines. Removal - Complete removal of tree as close to ground level as is reasonable and safe, using safety practices as outlined in ANSI Z133.1 safety standard. NO PARKING SIGNS REQUIRED - In order to service this tree, it is imperative that no parking signs be set out and enforced so that this work can be performed safely and smoothly. Permit Needed - Removal - A tree removal permit is required on this tree in order to service this tree without violating municipal codes. — Trunk — — Crown and Branches — — Roots and Root Collar — Unbalanced crown †LCR ______% Dead twigs/branches †____% overall Max. dia. ______ Broken/Hangers Number __________ Max. dia. ______ Over-extended branches † Pruning history Crown cleaned † Reduced † Flush cuts † Thinned † Topped † Other Raised † Lion-tailed † Cracks †___________________________________Lightning damage † Codominant †__________________________________Included bark † tĞĂŬĂƩĂĐŚŵĞŶƚƐ†___________________Cavity/Nest hole ____% circ.
