24) • Cottonwood, Populus trichocarpa, 34 "x90'. Retain. Tree is located on steep slope, and is important for <br />stability and hydrology. No large dead branches or previous breakages in canopy, with drip -line barely over top of <br />steep slope in event of breakage. <br />25) • Cottonwood, Populus trichocarpa, 24 "x60'. Remove. Severe tropism towards play area, with previously <br />broken crown resulting in stag head growth with multiple large sprouts with poor ratio in relation to trunk size and <br />weak attachments. Evidence of historic breakage with similar parts still present. <br />26) • Willow, Salix species, 8 "x6 "x6 "x36'. Retain. Located several feet down on to steep slope, with healthy <br />canopy. No noted concerns. <br />27) *Black locus, Robinia pseudoacacia, 8 "x45'. Remove. Cannot be adequately protected during construction. <br />28) *Black locus, Robinia pseudoacacia, 6 "x30. Remove. Cannot be adequately protected during construction. <br />29) *Big Leaf Maple, Acer macrophyllum, 22 "x36'. Retain. No evidence of previous breakages, with healthy and <br />vigorous canopy and structure typical of its species. Outside of the Striking Distance of play area and foot traffic in <br />the unlikely event of partial failure. <br />30) *Black locus, Robinia pseudoacacia, 7 stems 8" and less x 30'. One 14 "x45' trunk. Remove. Trees are in <br />intended play area with engineered surface and must be removed. <br />Sheet 6, East Side of Page <br />1) *Big Leaf Maple, Acer macrophyllum, 18 "x40'. Remove. Tree cannot be adequately protected during <br />construction and is in middle of open play area. <br />2) *Big Leaf Maple, Acer macrophyllum, 12 "x14 "x40'. Retain. Healthy crown and canopy with favorable growth <br />structure and no evidence of previous breakage. Lower branches may need to be lifted to accommodate <br />construction equipment mobilization. <br />3) *Big Leaf Maple, Acer macrophyllum, 20 "x40'. Retain. Favorable grow structure, with healthy canopy and no <br />noted concerns or defects. Located on edge of sensitive slope and outside of striking distance of nearby targets <br />and play areas. <br />4) • Big Leaf Maple, Acer macrophyllum, 28 "x45'. Healthy appearance and structure with no evidence of previous <br />breakage, and no noted concerns. Well outside of the distance of any targets in the unlikely event of failure. <br />139 <br />
