Arborist Report. Revised February 1,2017. HortScience,Inc. The Village at Valley Trails. Ponderosa Homes. Page 3 Twelve(12)coast redwoods were - - assessed. Included in this group were 11 . trees in the landscape areas west of the •: parking lot and surrounding the church building. Coast redwood#244 was just off- - site to the east. Redwoods were semi- j. it, mature in form and development,with trunk . -. _ -4-' Y diameters between 12"and 22". Nine(9) ' • , had diameters between 14 and 16'. Trees `'' . �, had good form and structure,but health ., , ' was variable. As a result,8 trees were in fair condition,two were poor,and 2 were good. Most had twig dieback and thin ' canopies of foliage,indicative of drought • . , stress. The one exception to this was '``~` . coast redwood#228,which was benefiting from excess soil moisture associated with a -• • nearby leaking pipe(Photo 2). Coast I� t':? redwoods planted outside their native =�'� , range can be expected to show drought- related stress,such as foliar dieback, unless regularly irrigated. - Photo 2:Looking south at coast redwoods#228 (left)and#229,230,231 (right). Note the difference canopy density. Tree#228 received additional water from nearby leaking pipe. Five Gallery pears(#235,236,237,238,and 242 and London planes#239,240,241 were located off-site between the trail and the southern property boundary. These trees were all young,with diameters between T and 11'.A sixth Gallery pear#243 was located on the eastern property line and was semi-mature at 16'. Seven trees were in good condition while Callery pear#242 was fair. Most of these trees had good,upright forms as a result of having been planted in close proximity to one another, The remaining four species were represented by single individuals,including: e Coast live oak#234 was located on the southern property line. It was mature,at 27"in diameter and was in good condition,with a full crown. n Chinese elm#245 was located just off-site along the northern boundary. It was semi-mature,with two trunks estimated at 15'and 13'in diameter. It was in good condition and the southern stem extended approximately 25'over the fence and onto the development site. a California pepper#246 was young,with multiple trunks measuring 4"to 7"in diameter. It was located adjacent to the fence on the northern boundary of the site. It had fair structure and was in good condition. e Silver maple#247 was located just off-site along the northern boundary. It was mature and estimated at 20"in diameter. The tree had been topped at some point in the past and was in fair condition. Portions of its canopy extended approximately 25'over the fence and onto the development site.
