ExecutiveSummary MelbourneTreeCarewas requestedbyRodQuince toproduce an impact assessmentreportinregardstoaproposeddevelopmentandthepotentialimpactsontreeslocatedinCaloolaReserve to thenorthof thesubjectsite,andstreet trees locatedadjacent tothesubjectsite.Theimpactassessmenthasdeterminedthatthereisminorencroachment(<10%)intotheTreeProtectionZonesoftwo(2)treeslocatedinCaloolaReserve,one(1)streettreelocated on Atkinson Street, and one (1) street tree located on Dalgety Street. It isconsidered that as these encroachments are minor, and the trees can remain viableduringandafterconstruction.Theimpactassessmentalsodeterminedthatthereismajorencroachment(>10%)intotheTreeProtectionZones(TPZ)ofthree(3)streettreeslocatedonDalgetyStreet.TheStructuralRootZones(SRZ)ofthesetreeswerecalculatedtodetermineifanystructuralrootswouldbeimpactedbytheproposeddevelopmentwhereitwasfoundthatthereisnoencroachment intoSRZof these treesby theproposeddevelopment. It is expectedthat the trees can remain viable, as the encroachment into the TPZ of these trees is<20%.The removal of all vegetation within the subject site is required to facilitate theproposeddevelopment.A Tree Protection Management Plan (TPMP) and tree protection measures are alsoincluded in this report. It is recommended all measures be followed tominimise theimpact of the proposed development on trees on adjoining properties and the naturestripdirectlyadjacenttothesubjectsite.
