Contaminated Soils Management Plan 1.0 INTRODUCTION This planning report and assessment of effects is submitted in support of the resource consent applications to Auckland Council for works within Westhaven Marina by Panuku Development Auckland (Panuku). Figure 1: Westhaven Marina Aerial View The proposal includes an extension of the north-western breakwater and causeway (via reclamation) to connect to the north-eastern breakwater in order to provide public open space and parking, as well as access to berthage. The public open space has been designed in conjunction with the Panuku Mana Whenua Forum. The proposal also includes the conversion of 103 existing pile moorings to 117 marina berthage in order to meet public demand for additional marina berthage in Westhaven. Public access to and along the Coastal Marine Area (CMA) is proposed via a public promenade around the coastal edge. The applicant requests public notification of the application. 1 Figure 2: Proposed Marina Berths Tamaki Herenga Waka (Westhaven) Precinct is specifically recognised within the Auckland Unitary Plan and the purpose of the precinct is to provide for the use and development of the marina. Westhaven has been the focus for recreational and competitive boating activities within Auckland for many years. Outside of the Unitary Plan controls and requirements, the Westhaven Marina management team have launched a programme to continually and progressively improve the environment within and around Westhaven. Previous improvements that have been undertaken include the following environmental and planning improvements: 2 Enhancing the public access and general amenities of Westhaven, such as the boardwalk around the marina, public amenities such as seating and water fountains. Replacement of existing H6 treated timber piles (treated timber piles for marine environments) with a combination of concrete or steel piles encapsulated with a protective coating such as polyethylene sleeves in order to improve water quality by avoiding leaching from timber piles in the Coastal Marine Area; All materials now chosen within the marina are sustainable and based on life expectancy. For example this includes utilising fastening devices made from long lasting composite materials as opposed to galvanised steel (which corrodes in the coastal environment and only lasts for 15 years before requiring replacement). Further, any timber materials are sourced from sustainable forests. Stormwater treatment devices have been progressively installed around Westhaven in order to improve the quality of discharges. The pile berth redevelopment project (subject of this application) will result in further enhancements for the Westhaven Marina and will include the following specific environmental improvements/effects: The opportunity to provide improved public access to wider parts of the marina through a new public space which has been designed in conjunction with iwi though the Panuku Mana Whenua Forum. The conversion of 103 existing pile berths to 117 marina berths, which is where the current demand lies. A number of pile moorings will still remain after the completion of the works (to the east of the proposed works) The removal of hundreds of old treated timber piles and use of concrete or steel ones instead.
