Davidon Homes, July 2007 HortScience, Inc. <br />Tree Report, Woodside Apartments Page 2 <br />Descrjption of Trees <br />Forty-three (43) trees, representing six (6) species, were assessed. Descriptions of each <br />tree are provided in the Tree Survey Forms and locations are plotted on the Tree <br />r ~ Survey Map (see Attachments). <br />Tree condition was evenly divided between fair (21 trees, or 49% of the population) and <br />I <br />'f good (with 22 trees, or 51 % of the population). Table 1, following page, provides a~ <br />summary of tree condition by species. <br />The most common spades surveyed was sweet gum, with 22 trees, or 51 % of the <br />population. The next most common species was coast redwood, with 12 trees, or 28% of <br />the population. <br />Certain species had performed better than others, due in part to the maintenance <br />practices employed. Coast redwoods had performed well, however, many had been <br />planted in dose proximity to one another and groups of trees were never thinned. <br />Additionally, several of the trees were planted in dose proximity to buildings, requiring <br />they be pruned to clear the structures for maintenance. <br />Photo 1: A row of sweet. gums planted on <br />Haas Avenue in dose proximity to utility <br />lines (blue lines). Pruning for utility line <br />clearance had topped some trees. Those <br />that had not been topped previously will <br />likely be topped in the future. Surface <br />rooting was noted on 15 of the 22 sweet <br />gums surveyed (inset). <br />Where sweet gums had been planted beneath, or in dose proximity to utility lines running <br />along Haas Avenue, utility line clearance pruning had affected tree condition (Photo 1). <br />Four (4) of the 11 sweet gums surveyed along Haas Avenue had been topped for utility <br />line clearance. Additionally, 15 of the sweet gums had notable surface root development, <br />displadng infrastructure in two instances. <br />
