1 Constraint maps Introduction Roads of national significance Wellington Northern Corridor Ōtaki to north of expressway Seven maps showing areas of constraint have been prepared as background information for the initial consultation phase of the Ōtaki to North of project. Something may be seen as a constraint for many reasons, including heritage, tangata whenua, ecology, landscape, hazards, land ownership and land use. All these factors will inform the project team and stakeholders in identifying possible expressway route options. It s important that we identify all constraints during the early stages of the project. Once we know and understand what they are, the team will be able to identify potential routes for the expressway and come back to the community for feedback on them. If you think we have missed anything, please tell us. You can tell us what you think via: info@o2l.co.nz Post: The Ōtaki to team, PO Box 084, Wellington 614 Phone: You can also visit the project website on otaki-levin-project Please send us your feedback by Friday 23 September Wellington Northern Corridor N The Wellington Northern Corridor runs from Wellington Airport to north of and completing it will assist regional and national economic growth as well as deliver a range of benefits including: support for a growing regional population support for the transport of increasing freight volumes relief from the current road congestion improved safety for road users improved journey time reliability improved access to Wellington s key facilities such as the port, central business district, airport and hospitals. The Wellington Northern Corridor is made up of the following eight sections as shown on the map. The focus for the next two to three years is on investigations and consents. Following this, design and construction work will be undertaken in phases as follows: Phase 1 Transport improvements around the Basin Reserve Four-lane expressway from to Wellington Airport Ngauranga to Aotea Quay Improving MacKays access to to Peka Wellington's Pekaport, central business district, airport and hospital Peka Peka to Supporting a growing population, increasing freight Phase volumes 2 and economic growth Providing relief from severe congestion on the state highways and local road networks Linden to MacKays Transmission Gully Phase 3 Airport to Mt Victoria Tunnel including tunnel duplication Terrace Tunnel duplication to

2 ! 1 Map 1. Zoning and land ownership This is an indicative map of population density. It shows the centrepoint of each parcel of land in the area, giving an overall impression of where people live. Land ownership was identified from the Land Information New Zealand LINZ database, and land was mapped on the basis of surveyed boundary lines. Organisations with a responsibility for statutory planning in this area are the District Council, Horizons Regional Council, Greater Wellington Regional Council and Kapiti Coast District Council. Information was gathered from each of their District and Regional plans. Areas zoned for residential, open space and conservation were identified as particular constraints due to high population density and potential incompatibility with an expressway. Areas of potential growth are also identified, although plan changes would be necessary for any residential development to occur. KOPUTAROA ROAD WAITARERE BEACH ROAD MOUTERE ROAD HOKIO BEA C H ROAD!

3 Map 2. Heritage areas Archaeological sites within the area were identified from the NZ Archaeological Association database. These are known sites and the locations are approximate to within 100m. Notable trees and historic buildings were identified from the and Kapiti Coast District Plans. " Historic Buildings Ý Notable Trees! Known Archaeological Sites

4 Map 3. Tangata whenua areas of significance Maori-owned land in multiple or Trust ownership/administration as per the Te Ture Whenua Maori Act 1993 was identified on the basis of LINZ survey and ownership information. The areas of cultural significance were identified and mapped on the basis of advice from the project s Maori advisor and discussions with tangata whenua. Tangata Whenua Areas of Significance Multiple-owned Maori Land Known Areas of Cultural Significance Places of Significance

5 Map 4. Landscape/urban design constraints This map is based on detailed site analysis by a landscape expert and takes into account landform, vegetation, waterways, aesthetic quality and distinctiveness. Other factors such as historical associations, recreational values, or values that tangata whenua and others might associate with a landscape are also considered here. Landscape Features Built or Natural Landscape / Urban Design Constraints Low High

6 Map. Ecological areas of significance This map brings together a range of information. The Department of Conservation provided information on areas of the conservation estate with specific ecological values. Threatened land was also identified, included privately-owned land with recognised ecological values. Horizons Regional Council provided information about surface water management including sites which provide habitat for native New Zealand species. Threatened Flora / Fauna Ecological Areas of Significance Note: Some shaded areas extend outside the Study Area Nationally Significant Regional / District Significance

7 Map 6. Hazards Seismic hazards and hazards related to soft ground conditions are the predominant geotechnical issues that could impact on the study area. Information for this map came from a desktop study of ground conditions, groundwater and possible geotechnical hazards. A number of general ground engineering hazards were identified. Data on contaminated sites was obtained from the Hazardous Activities and Industries List HAIL and contaminated sites register held by Horizons Regional Council. Fault Lines Land at Risk of Accelerated Erosion Landfill Liquefaction Potential Low Moderate High Tsunami Hazard Medium Low Contaminated Land Managed / remediated Unknown / suspected Confirmed

8 Map 7. Flooding Data was obtained from Horizons Regional Council. Given the lack of comprehensive flood data for the entire study area, the data is based on areas known to be prone to flooding within 20m of a waterway.! Potential for Flooding Waterways / s
