For more information visit www.AT.govt.nz/CRL CRL Designation Alterations As part of the CRL project, some alterations are required to the CRL and KiwiRail North Auckland Line designations. The alterations are driven by design refinements and value engineering opportunities, where value is defined not only as reduction in cost, but also as improvements in operational and construction safety, public amenity and environmental impact. The following alterations are proposed: • Removing a proposal to grade separate vehicle, pedestrian and cycle traffic at Porters Ave over the NAL and CRL rail tracks and the provision of a new cycle and pedestrian overbridge at Porters Ave. • Provision for the construction, operation and maintenance of the redeveloped Mt Eden Station which includes a new platform to service the CRL, a plant building and portal headhouse/vent building. • Provision for the construction of new roads to service the redeveloped Mt Eden Station, including extensions to Flower, Korari, Ruru and Nikau Streets and a new bridge at Ruru Street. • Removal of 17 willow trees from the road reserve at Boston Road. • Provision for alternative access at 32 Normanby Road from that specified by the CRL conditions. • Alteration of the boundaries of the CRL Designation 6 to provide for the construction, operation and maintenance of the CRL over 14-22 Boston Road and 11 Water Street. • Extension of the CRL Designation 6 boundary to provide additional construction support areas (CSA) at Boston Road, Mt Eden Road and in the vicinity of Dominion Road to facilitate construction of the CRL. • Extension of CRL Designation 3 (strata) to provide a protection designation in the area for future withdrawal of CRL Designation 5 (Newton Station). • Extension of the KiwiRail North Auckland Line (NAL) boundary to provide for the ongoing operation and maintenance of the realigned NAL track alignment, enabling the construction of the CRL tracks in between the NAL alignment and achieving a minimum 4.0m clearance between the centreline of each alignment, at the following locations: - Road reserve between 8 Haultain Street and 5-7 Fenton Street. - Road reserve between 49-51 Boston Road and east of Severn Road. - 14-22 Boston Road. - 11 Water Street. - 26 and 28 Mt Eden Road. • Extension of the KiwiRail / NAL boundary over Porters Ave to provide for signaling infrastructure. • Extension of the KiwiRail NAL boundary to provide for existing tracks where there is currently a gap in the existing NAL designation, at the following locations: - The Normanby Road level crossing in part. - Boston Road beneath the State Highway 1 Newmarket Viaduct CRL0061 J001465 KH 04.07.16 K684+650 K684+650 K684+600 MT EDEN / NAL EAST (ACZ M) M1 CSA 5 G N I W A R D O T E N I L N I O J 4 0 0 2 - G R D - 0 0 0 - E M R - W Y S - L R C BOSTON ROAD NUGENT ST MT EDEN ROAD WATER ST BURLEIGH ROAD MT EDEN ROAD SHADDOCK ST NIKAU ST AUBURN ST SEVERN ST D A O R N O T S O B D A O R R E D U A L NORMANBY ROAD CSA 5 K685+050 K685+000 K684+950 K684+900 K684+850 K684+800 K684+750 K684+700 684+650 K685+050 K685+000 K684+950 K684+900 K684+850 K684+800 K684+750 K684+700 MT EDEN / NAL WEST (ACZ M) M2 CSA 4 M1 WEST FACING CONNECTION M2 EAST FACING CONNECTION CSA 4 MT EDEN CONSTRUCTION SUPPORT AREA CSA 5 NAL TIE IN CONSTRUCTION SUPPORT AREA NOTES: JOIN LINE TO DRAWING CRL-SYW-RME-000-DRG-2005 JOIN LINE TO DRAWING CRL-SYW-RME-000-DRG-2004 NEW NORTH ROAD KORARI ST RURU ST FLOWER ST NGAHURA ST NEW NORTH ROAD PORTERS AVE FENTON ST WYNYARD ROAD BRENTWOOD AVE BRENTWOOD AVE DOMINION ROAD ACE PLACE NEW NORTH ROAD AKIRAHO ST MT EDEN ROAD ENFIELD ST MT EDEN ROAD CSA 5 M1 PROPOSED DRIVEN TUNNEL PROPOSED MINED TUNNEL SHAFTS / CUT AND COVER OPEN TRENCH / ROAD BRIDGE / ABOVE GROUND STRUCTURE / PLATFORM LEGEND CRL DESIGNATION ALIGNMENT CSA KIWIRAIL "THESE DRAWINGS PRESENT REFERENCE DESIGN AND CONSTRUCTION METHODOLOGY INFORMATION TO ENABLE TECHNICAL SPECIALISTS TO ASSESS POTENTIAL EFFECTS ON THE ENVIRONMENT AS PART OF A REGIONAL CONSENT APPLICATION.
