David Cannon M.Env.Eng.Sc, B.Env.Sc.Adv (Hons) Corporate Member - PIA ENVIRONMENTAL ASSESSMENT - 58 LOT RESIDENTIAL SUBDIVISION OF LOT 682 i DP 568678, LOT 705 DP 613881 AND LOT 810 DP 247285, MANYANA DRIVE, MANYANA EXECUTIVE SUMMARY This application proposes a fifty eight (58) lot subdivision on the subject site, which consists of Lot 682 DP 568678, Lot 705 DP 613881 and Lot 810 DP 247285 Manyana Drive, Manyana. The subject land is an irregular shaped area of some 9.5 ha with maximum north-south and east-west dimensions of 384 m and 530 m respectively. The site is located along the eastern edge of the existing developed residential area of Manyana in the area bounded by Manyana Drive, Sunset Strip, The Palisade, The Barbette, The Bounty and the fore dunes of Manyana Beach. That part of the land subject to development lies approximately 300 m west of Manyana Beach. The subject site is zoned part Zone 2(a1) Residential, with a portion in the east zoned 2(e) Village, (deferred from Shoalhaven LEP 1985, Amendment No. 62). The original subdivision layout considered a 71 lot residential subdivision of the subject site. The layout comprised a mixture of Torrens Title lots (proposed lots 101-151) and Neighbourhood Lots (proposed Lots 1-21) under the Community Land Development Act. Proposed Lot 1 was to form an Association Property lot in favour of the Neighbourhood Lots. On 9 June 2006, the Director-General of the Department of Planning, under delegation from the Minister for Planning (the Minister), formed the opinion that the proposed subdivision was considered a Project to which Part 3A of the EP&A Act applies. The Director-Generals environmental assessment requirements for the preparation of the Environmental Assessment Report (EAR) were received in October 2006 and listed 15 key project specific issues, which are provided in the Table below, along with the relevant sections of the Environmental Assessment where the issues have been addressed. A range of environmental studies were undertaken and following a more detailed flora and fauna assessment of the subject site, three endangered ecological communities (EECs) were found to exist on the site. At this point it was determined that there was potential for the proposed subdivision layout to negatively impact on two of those communities (Swamp Oak Floodplain Forest, and Swamp Sclerophyll Forest). In addition, having considered concerns raised by the Department of Planning, the Department of Natural Resources and Shoalhaven City Council, urban design principles and the environmental impacts of the proposed layouts it was concluded that the option for a 71 lot subdivision was not viable due to the likely environmental impacts. Therefore fourteen (14) lots along the southern side of Sunset Strip and the eastern side of the proposed loop road were removed and the project design modified. Subsequently three alternate layouts were considered before arriving at the final option for the proposed fifty eight (58) lot subdivision. The preferred layout was chosen for a number of reasons including the use of a perimeter loop road and Watkinson Apperley Pty Limited 51 Graham Street, Nowra NSW 2541 ENVIRONMENTAL ASSESSMENT - 58 LOT RESIDENTIAL SUBDIVISION OF LOT 682 ii DP 568678, LOT 705 DP 613881 AND LOT 810 DP 247285, MANYANA DRIVE, MANYANA connecting road off Manyana Drive. This street design further reduces the impact on the EEC, improves bushfire protection and enhances opportunities for public access to foreshore areas while providing public road access to all lots within the subdivision and improving the permeability within the street network.
