Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development Agency7 Landscape7.1 IntroductionThe site is bounded by streets on all sides. To the north and east are the suburban streets of Page,Chowne and Creswell, with relatively narrow carriageways, and wide grass verges on both sides.This perimeter has a stand of deciduous trees on the edge, which provides a fairly consistent lightvegetative screen to the site.To the west is Anzac Park East, which is a peripheral access road for Anzac Parade. It is relativelynarrow, with parking on one side. The wide median between the peripheral road and Anzac Paradesupports a dense stand of mature Eucalypts and a series of monuments. This road is separatedfrom the site by a very dense stand of conifers.Constitution Avenue forms the southern boundary. The site sits up to three metres above theAvenue on a grass slope that diminishes from east to west. A stand of Stone Pines dominates thisedge.The site is a broad grassy area with a strong edge defined by the stands of trees. The current sitecharacter has evolved from past agricultural uses, which included a small farm dam at the low pointtoward the centre of the site. This dam and some of the surrounding area has been used to illegallydump builders’ rubble, including material containing some contaminants. Traces of the originaldrainage system are evident in the topography of the site.Local residents use the site mostly for dog walking, evidenced by well-worn beaten earth pathsrunning along the edges under the deciduous trees. Tracks are also formed where people cutthrough the field from Constitution Avenue to Campbell, and to Anzac Park East and Anzac Parade.Predominantly, the site is valued by Campbell residents as a green edge to their suburb, and abuffer to development along Constitution Avenue.7.2 Tree AssessmentA tree report was completed for the existing trees on Campbell Section 5 based on an Arboristsassessment, both are attached as Appendix 7. Arborist investigations found that:The stand of Pinus radiata adjacent to Anzac Park East in the north west are generallysenescent and should be removed for public safety. These trees are also classed as a weedor nuisance plant in Canberra;The Cupressus arizonica adjacent to Anzac Park East in the west are a common tree inCanberra that does well in these conditions, and together the trees form a fine stand;The Pinus pinea in the south west of the site along Constitution Avenue are less common,and together form a fine stand;The deciduous trees along perimeter of the site adjacent to Page, Chowne and CreswellStreets are generally healthy and robust in this situation and were planted later than othertrees. Removal of some weedy tree species is necessary;There are three groups of Quercus sp. toward the centre of the site that are consideredsignificant for age and form; andNovember 2012 Cardno 34
