Environment Executive Summary Peter Brett Associates has been appointed by University of Cambridge to provide environmental advice for input to the Area Development Framework for the Old Press / Mill Lane site, a potential development site close to the centre of Cambridge. The site is bounded by Silver Street to the north, Trumpington Street to the east and Little St Mary’s Lane to the south. It is approximately 1.75ha. The River Cam lies immediately to the west of the site. Current land uses include University, academic, research and administrative buildings, two public houses, private dwellings, a church and buildings used for commercial purposes. A review of pertinent environmental policy was undertaken with particular emphasis on policies within the 2006 adopted Local Plan for the City of Cambridge. A desk-based search of environmental information was undertaken including searches of government agency websites, in particular “Magic” and the Heritage Gateway. In addition, an Envirocheck Report commissioned for the site was reviewed; the report comprises historical OS maps and regulatory information. The key environmental issues identified by the environmental searches were flood risk and the effect the development may have on townscape. The western part of the site falls within the Environment Agency flood zone 2 which gives rise to a risk of flooding of between 1 in 100 and 1 in 1000 in any given year. Design of the proposed development must take account of flood risk and surface water drainage. Flood Risk Assessment, will be required which will clarify the extent of flood zone 2 in relation to the site, it should be commissioned in time to inform evolution of the master plan. Townscape is an important issue for the preparation of the development framework. The site is in a Conservation Area and there are a number of listed buildings and buildings of local interest within the site. The effect of development on the setting of these buildings will require a sensitive approach. A number of other designations apply to adjacent land including the Green Belt (Laundress Green/Mill Pit) and a registered park and garden (Queens’ College). A number of subsidiary environmental issues were identified, which should also be considered as the scheme proposals develop. Amongst these are potential land contamination, archaeology, biodiversity, air quality and community and business. Given appropriate design and implementation of best practise during construction, none of these issues should be an impediment to development, but must be subject to further assessment in order that planning requirements are met and best practical environmental options are achieved.
