Whau bridge - access

Whau bridge – ground improvements

Whau bridge to Rosebank Domain

Whau bridge widening – cross section • Broad range of experts review construction activities • Pre-clearance and ongoing inspections for lizards, vegetation, trees and archaeology • Stormwater, erosion/sediment control, coastal area protection established before works begin and regular inspections • Ongoing monitoring of earthworks compliance, contaminated soils, noise, air quality, marine ecology and birds • Monitoring results to be issued to CLG

Whau bridge – shared path widening

Planting and trees • Coastal experience - native coastal species • Eco-sourced from Tamaki Ecological District • Appropriate ecotypes • Reference to existing vegetation • Pohutukawa at gateway locations

Environmental monitoring - overview • Broad range of experts review construction activities • Pre-clearance and ongoing inspections for lizards, vegetation, trees and archaeology • Stormwater, erosion/sediment control, coastal area protection established before works begin and regular inspections • Ongoing monitoring of earthworks compliance, contaminated soils, noise, air quality, marine ecology and birds • Monitoring results to be issued to Community Liaison Group

Te Atatu Construction Yard - Bird life • Dotterel nest found on earth stockpile in Construction yard • Fenced off to protect • Advice being sought from DOC

Environmental mitigation and legacy • Runoff receives a high standard of stormwater treatment • Landscape planting (grass swale & path edge, revetment) • Further mitigation options/outcomes being considered, eg: • Increased community awareness/education • Improved access to marine reserve, under Whau bridge • Viewing areas and seating along shared path • Greater plant and animal pest control • Celebration of heritage and culture • Revegetation of Traherne Island

How to find out more • Community Liaison Group (CLG) meetings • Freephone 0800 444 449 | Mention “Causeway” • Causeway News – regular project email updates • Project website, Google: SH16causeway • Info about upcoming work: media, advertising • Separate meetings for site or issue specific details • Communications and Stakeholder Manager, contact: • elizabeth.collins@sh16causeway.co.nz

Summary • Construction progressively moving along SH16 to upgrade the corridor by late 2016 • Causeway Alliance is committed to working closely with the community and monitoring works to minimise effects on environment • Project outcome is to ‘tread lightly’ on the surrounding environment and marine reserve • Reviewing options for including further environmental mitigation projects
