Studies

The studies we have done to assess the potential impact of the Major Housing Project

Specialist scientific assessments

We carried out a number of specialist scientific assessments to assess the potential impact of the proposals. The assessments were in the areas outlined below.  

You can find the reports, for the assessments carried out, at the bottom of this page.

Archaeology

A desk top survey covering the new road and Marsh Lane access road was carried out in June 2014. There are no designated heritage assets in the area, but there is a high probability of finding medieval saltern remains and post-medieval deposits. Test pits and on-site monitoring during the works will ensure any finds are correctly identified and recorded.

Update 28 May 2015: Archaeological work is taking place on site. Soil samples have been taken and some trenches dug. Depending on what they find, this work could take around five weeks. The work is being undertaken by Oxford Archaeology and is being overseen by NAU Archaeology.

Air quality

An assessment carried out in Aug 2014, when Lynnsport 2 still formed part of the proposals and the overall impact was "considered to be 'negligible' to 'slight beneficial' and therefore not significant".

Ecology

A number of habitat and species-specific surveys were carried out during 2014 and summarised into an ecological report in August 2014. This was submitted to accompany the planning application for the access road. 

Studies covered reptiles, amphibians, birds, bats and water voles. Where necessary, mitigation strategies were recommended, and will be implemented as appropriate before and during the works.

Water voles

It has been confirmed that there are no water voles in the stock pond at Lynnsport which is due to be drained. 

However, there are water voles in the Bawsey Drain. A mitigation plan has been produced to ensure that the water voles are encouraged into alternative habitats before any work to the drain is started (the work involves building a box culvert to form a bridge over the drain for the new road). 

A full inspection by a trained ecologist will take place, to ensure that the mitigation plan has been implemented and has been effective.

Geology and soils

Ground surveys have been carried out to assess the soils and assess the load-bearing capacity of the underlying ground to accept the structures to be built on it. And to inform the depth of the foundations required.

See geo technical and geo environmental assessments for the planning application details for the new road.

Noise

An acoustic assessment took place in Sept 2014 to consider the noise impact of the scheme. Whilst the nearest properties will be affected in the short term during the construction works, mitigation measures will be put in place. Longer-term effects are considered to be moderate.

Water and flood risk

Considerable regard is being given to the potential implications for both fluvial and tidal flooding and the mitigation required to avoid this. The scheme includes improvements to the overall drainage provision so that the area will have greater flood protection than at present.

See flood risk assessment for the planning application details for the new road.

Trees

An arboricultural survey has been carried out to assess the value of the trees and hedgerows on the site. This will ensure that as many trees are retained as possible and that measures are put in place to protect those closest to the works. Report written in June 2014 and updated Oct 2014.

The findings and recommendations of these surveys will be taken into account and further surveys will be carried out where necessary.
