Project-Specific Issues and Requirements
The approach to landscape management should take into account the following:
• preserving and complimenting the existing landscape and rural qualities that characterise
the receiving environment, through retaining existing vegetation where possible and
replicating existing landscape / planting patterns;
• protecting valued view shafts such as views to the Port Hills and Canterbury Foothills by
retaining and or providing gaps in existing and proposed vegetation;
• identifying areas where plantings are required for visual screening and improving amenity.
The visual screening will be located to control headlight glare, “back dropping” curves and
intersections and obscuring views of the motorway from adjoining residential properties;
• the provision of screen planting to ensure a high quality experience for users of the
motorway;
• choosing plant species to reflect the local landscape character;
• the selection of native and exotic plant species that are appropriate to and will thrive in the
local environment;
• the development of a visual theme to promote consistency and continuity with CSM1 and
other local sections of SH1; and
• earth mounding as enhancement for a length of 700 m to the south of the proposed
alignment, between Trents Road and Shands Road. These mounds will be approximately
2m high gently contoured features with areas of landscape planting (trees) to provide visual
amenity to neighbouring properties and motorway users.
• specific riparian planting adjoining Stockwater races affected by the Project.
More detail regarding landscaping measures for the Project is set out in Appendix E of the CEMP,
which contains the Draft Landscape Management Plan.
CEMP Expectations for the appointed Principal Contractor
The guidance and expectations set out in the SEMP 005 Landscape Management Plan within
Appendix E of this CEMP should be followed and where necessary be reviewed and updated once a
detailed construction programme and build methodology has been agreed with the NZTA by the
Principal Contractor and the Construction Environmental Manager.
2.3.6 Ecological management (freshwater, terrestrial)
Potential Impacts
Freshwater – There are no natural watercourses throughout the project length however there are a
number of stock water races that maintain aquatic habitats. Potential adverse effects on aquatic
ecology during construction relate to potential sedimentation and contamination of water races and
habitat disturbance.
Terrestrial - Adverse effects on terrestrial ecology will be most pronounced during construction
when sections of shelterbelt, stands of trees and areas of pasture are removed. The two potential
direct impacts on terrestrial ecology are the loss of habitat through clearance and earthworks; and
disturbance, displacement, injury and mortality of birds and lizards.
