noise & traffic

Napier Port has engaged acoustic experts, Marshall Day, to investigate the noise impacts of the proposed wharf development, in particular the new location and likely terminal layout. Marshall Day have been working with Napier Port for many years so are well aware Napier Port’s noise environment.

Noise is assessed in terms of the New Zealand Port Noise Standard. Construction noise, and our noise mitigate initiatives are also to be included.

Initial work suggests that there will be a minor increase in noise, predominantly as a result of growth. Preliminary findings are:

“MDA has updated the Port of Napier noise model to represent both current (2016) and future (2026) operations with Wharf 6 (the proposed wharf) and forecast growth. It is considered that the noise model provides an accurate representation of current and future port noise emissions during peak operating periods.

In summary:

Marshall Day is also assessing the impact of construction noise from the proposed wharf project.

It has found the greatest construction noise would be associated with driving in wharf piles.

The predicted noise levels will meet with the daytime construction noise limits at the closest residential receivers.

“Noise from other activities associated with the construction works such as excavators, crane operations, truck and vessel movements would be at the lower level, and would be generally similar in level and character to existing port operations.”

Construction noise will be managed by hours of work and best practice construction noise management through a construction noise management plan.

Traffic Noise

Napier Port is also looking at the impact that the development will have on roading and traffic.

We have commissioned international engineering consultancy, MWH, to undertake an independent review of the traffic and provide a report which will be a part of the resource consent application.

The traffic implications of the actual construction process will be described, and we are looking at the implications of the growing volume of freight.

Early indications are increased traffic flows during the construction phase will be well within the capability of the roading and intersections.

Traffic growth as a result of Port growth will be managed on an ongoing basis in association with the Council and NZTA.

VBS Trucking System

 

Napier Port has substantially reduced congestion at the Port entrance by introducing a new Vehicle Booking System (VBS).
