Oak #54 was <br />especially striking with a wide- <br />spreading crown (Photo 4). <br /> <br /> <br />Coast redwoods #30 and 31 were <br />located off-site. Their crowns <br />extended approximately 12 feet into <br />the project area. The redwoods <br />had good upright form and <br />structure. Tree #30 was in good <br />condition with a healthy crown and <br />tree #31 was in fair condition with a <br />sparse crown. Trees were semi- <br />mature to mature in development with an average trunk diameter of 20 inches. <br /> <br />London planes #59 and 60 were street trees located adjacent to Black Ave. They were growing <br />in 5-foot tree wells and were under utility lines. The planes were in fair condition and had been <br />topped for utility clearance. They were semi-mature in development with a trunk diameter of 16 <br />inches. <br /> <br />Two southern magnolias were growing in turf near the building entrance. Tree #14 was in fair <br />condition with girdling surface roots and a healthy crown. Tree #27 was in poor condition with <br />large surface roots and moderate twig and branch dieback. The magnolias were semi-mature in <br />development with an average trunk diameter of 16 inches. <br /> <br />The remaining species were represented by one tree: <br /> <br />• Evergreen ash #28 was semi-mature in development. Its codominant stems measured <br />10 and 9 inches in diameter. The ash was in fair condition with a healthy crown. <br /> <br />• Hackberry #57 was located off-site. The tree was in fair condition and had vigorous bud <br />growth. This multi-stemmed tree was semi-mature with an average trunk diameter of 8 <br />inches. <br /> <br />• Sawleaf zelkova #12 was mature in development with a trunk diameter of 19 inches. The <br />zelkova was located in a planting space that measured 6 feet by 10 feet. Its large <br />surface roots were displacing the surrounding hardscape. The tree was in fair condition <br />with moderate twig and branch dieback. <br /> <br />Photo 4. Off-site valley oak #54 <br />was in good condition and had a <br />wide spreading crown.
