This statement sets out the response from Cambridge City Council in response to the Examination Matter 10 in relation to Noise and Vibration. 2. This document needs to be read alongside the Examination Statement for Transport Assessment and Traffic Modelling submitted by Cambridge City Council (ID10030344/CCC/4) 3. This statement sets out the response from Cambridge City Council in relation to Noise and Vibration issues arising from the Highway England’s Environmental Statement of December 2014 and the CHARM2 Traffic Modelling associated with the A14 Cambridge to Huntingdon improvement scheme. 4. The documents referred to in this statement are listed in Appendix 1. Examination document reference numbers are used throughout for convenience. 5. This Document was prepared by Adam Finch, Senior Technical Officer, Environmental Quality and Growth Team, Cambridge City Council. He is an Experienced and Qualified officer with degree level qualifications in Environmental Science and discrete post graduate qualifications in acoustics, air quality and contaminated land. He has over 12 years of experience in both public and private sector roles consulting on the environmental impacts of development. Overview Officers from South Cambridgeshire District Council have provided separate commentary on the Inspectors Questions with regards to the potential impacts of noise and vibration. We are in agreement with those comments and much has been echoed in the documentary provided below. Chapter 14 of the ES concludes that a greater number of dwellings will benefit from improved noise levels than will be impacted adversely, However, there remains a significant element of uncertainty within the modelled noise output. This specifically relates to the CHARM 2 traffic forecasting model which has yet to be agreed with Cambridgeshire County Council. These issues are summarised below and the Noise and Vibration issues explored in more detail with reference to the specific questions raised by the inspector in this examination statement. The transport issues are addressed in 4 Statement by Cambridge City Council June 2015 detail in the Transport Assessment & Traffic Modelling Examination Statement. 1. Traffic forecasting: a. Traffic modelling presented in the ES is subject to a number of uncertainties identified by the County Council transport officers, in the CHARM 2 Traffic Model. Further work is being undertaken by HE with CCC and CCiC to address these. b. Traffic forecasts for the local road network in the north of Cambridge are of particular concern to Cambridge City Council. c. All of the presented in the ES Noise and Vibration forecasting is based upon those traffic forecasts. 2. Noise and Vibration Modelling a. The noise modelling exercise has not recognised all relevant receptors. Coverage of receptor locations such as parks and external amenity spaces is lacking. b. With the exception of various receptor locations, there is no provision of modelled outputs for the impacts of the scheme on a wider scale (i.e; where there is no receptor selected, it is not possible to accurately determine the impacts). c. Since the submission of the ES, new guidance (IAN185/15) has been issued providing details on more accurate modelling of road traffic “links”. d. The noise modelling assessment is focussed largely on the day-time impacts. There is little discussion of the impacts at night. e. Assessment of noise from borrow pits has been incorporated into the wider assessment of construction noise and vibration rather than being assessed under the National Planning Policy Guidance. f. For the City Council we have specific concerns about noise impacts on the Amenity of the City Council owned Crematorium near Madingley from changes to the road layout within the scheme. Responses to specific questions set out by the Examining Panel Author: Adam Finch Question Reference: Q1.10.1 Question: Does the assessment of noise effects in ES chapter 14 consider all appropriate residential receptors along the route, taking account of individual dwellings and 5 Statement by Cambridge City Council June 2015 communities? Response: Chapter 14 of the ES does largely consider the majority of residential receptors (including individual dwellings and communities). However, there is little or no discussion on other important receptors that are potentially impacted by the proposed scheme. One such receptor is the Cambridge City Crematorium (including the Gardens of Remembrance) which Is potentially impacted by a new local access road to its rear in addition to the impacts from the widening of the A14. There are various receptor locations identified (within the Crematorium, this is R747) for which the existing noise climate is considered. R747 is located to the front of the Crematorium where the noise climate is undoubtedly influenced by the A14 and not representative of the Gardens of Remembrance. Chapter 14 of the ES provides contour plots of the modelled noise output for the scheme without mitigation and contour plots for the scheme with mitigation. There is no provision of modelled output for the actual impact on existing noise levels. As such, it is difficult to assess the impact of the scheme at locations not identified as receptor locations (such as the rear of the Crematorium). This appears to be in conflict with the requirements of DMRB for which contour/modelled output is required for the impacts at all individual receptors and so allowing an assessment of the significance of the impact against the existing noise climate. Author: Adam Finch Question Reference: Q1.10.2 Question: Was the baseline data for the noise assessment agreed with local authorities? Please identify any matters where agreement was not reached and explain why. Response: The baseline data has been agreed with CCC. After discussions with the noise consultants, it was agreed that the model performs well along the Cambridge Northern Bypass when compared to the monitored noise levels at specified locations. 6 Statement by Cambridge City Council June 2015 Author: Adam Finch Question Reference: Q1.10.3 Question: Significant impacts from noise and vibration during construction are predicted to impact on both residential and non-residential receptors. How would site specific noise controls be agreed with the local authorities? Response: The applicant is to provide a detailed Code of Construction Practice (CoCP). The CoCP contains the details as to how construction
