A key priority for all large construction projects today
is care for the environment. That means carrying out
the works with the minimum of disruption to local
wildlife and vegetation whilst enhancing biodiversity
and reducing our carbon footprint.
Enironmental Impact Assessment (EIA)
This project meets the requirements of a “Schedule 2 project” within the EIA directive, and therefore an EIA screening opinion is required by Gwynedd Council and Natural Resources Wales.
Construction activities are likely to generate dust and vehicle emissions, and therefore appropriate measures will be implemented to reduce these emissions, ensuring disruption to residents and wildlife are kept to a minimum. Due to the scale of the work, it is unlikely that any significant impact on air quality would occur. Successful sub-contractors must detail how they would minimise dust emissions.
The Anglesey coastline is a designated AONB (Area of Outstanding Natural Beauty), however it is not expected that the works will infringe upon the AONB at all. Parts of Bangor are designated conservation areas, but again the scheme does not infringe on such areas. A landscape and visual appraisal has been undertaken and recommends careful planning is made to not obscure the views of properties. It also recommends that the new infrastructure and furniture should be designed so as to not visually-detract, using natural stone for cladding. See technical documents page for more.
A Preliminary Ecological Appraisal (PEA) has been prepared (see technical documents) which sets out the details of the ecological baseline and survey requirements, and provides details on what mitigation measures are needed to safeguard biodiversity. Key species considered are bats, otters, badgers, birds, reptiles and amphibians. A full list of surveys can be found in the PEA report.
Materials expected to be required to construct the scheme include concrete, steel and masonry. Any masonry facing incorporated as part of the scheme should match existing masonry features within the locality, and be sourced from the closest suitable supplier where possible. Waste hierarchy principles will minimise waste, and materials will be re-used on site where possible.
Noise and vibration
The proposed construction work is likely to generate noise and vibration levels that are above the existing levels, causing a disturbance to residents. Increases in noise and vibration can also impact biodiversity in the surrounding area. Increases in noise and vibration levels are likely to be confined to the construction phase, and working hours, and are likely to return to normal on completion of the works. Whilst there may be increases in noise and vibration levels, it is not expected that these increases would be significantly higher than existing traffic noise.
