The Expansion of Cambridge Biomedical CampusDesign and Access StatementAppendix 3- Biodiversity StatementIntroduction and backgroundThe Biodiveristy Statement is a synopsis of information coveredin the ES section 8 'Ecology' and in the Design Statementsection on 'Ecology'. These documents should be referred tofor a full account of the baseline survey, potential impacts andmitigation.Baseline surveyThe Baselines Survey is covered in ES Volume 1a Section 8.For convenience a brief synopsis is given below.The site mostly consists of large open arable fields generallycultivated to field boundaries, but there are a few headlands upto 2m wide. There are few hedgerows and the majority of theseare species poor hawthorn hedges with the occasional standardtree.A number of ditches which cross the site including Red CrossLane Drain a City Wildlife Site (CiWS). The majority of theditches are periodically dry.Long Road Plantation – a wooded area – forms part of thenorthern boundary of the site and there is a strip of neutralgrassland along the Trumpington dismantled railway CountyWildlife Site.Grass snakes and Common Lizard are present and fourspecies of bats have been recorded. Twenty eight species ofbirds have been recorded on site including large flocks orGolden Plover. Brown hares are recorded on site. Forty sevenspecies of aquatic invertebrates have been recorded inHobson's Brook.MitigationMitigation is covered in ES Volume 1a Section 8. Forconvenience a brief synopsis is given below.Mitigation measures will help ensure that the effects of thedevelopment on biodiversity are minimised wherever possibleand also aim to enhance features and promote biodiversitygain. A Construction Environmental Management Plan will becompiled prior to works commencing on site to ensure the bestenvironmental working practice during construction. It willinclude for example avoiding sensitive stages of species lifecycles,such as the breeding bird season, provision ofprotective fencing and the phasing of works so that not all of thehabitats are removed at the same time.The ecology and potential habitat value will be an importantconsideration in the selection of appropriate landscapesolutions with species of plants chosen according to theirwildlife benefit.Bat boxes and bird nesting features will be provided, as well asinvertebrate hibernacula.Wooded areas and wetlands in the form of sustainable drainagesystems will also help diversify habitat, helping to provide amosaic of habitats across the site which will benefit wildlife.Maintenance proposals for these areas will come forward at alater stage.ImpactsA summary of the impacts of the construction and site operationis given in Table 8.5 of the ES. A summary of residual impactsis given in Table 8.7. For convenience a brief synopsis is givenbelow.The proposed development will alter the character of the sitefrom one that is predominantly a farmed landscape to a builtenvironment. The residual impacts can be summarised asfollows:• significant negative impacts on breeding birds,wintering/passage birds and brown hare;• no significant impact on arable land, Hobson's Brook,Woodland areas, Nine Wells Springs LNR, badger andwater vole; and• significant positive impact on boundaries, on sitewatercourses and bats.35
The Expansion of Cambridge Biomedical CampusDesign and Access StatementAppendix 4 - Lighting StrategyIntroductionThe Cambridge Southern Fringe Area Development Frameworkrequires various strategies to be prepared to support a planningapplication. Lighting is one of these requirements. ThisLighting Strategy covers the main lighting principles by whichfurther applications with respect to the design of the night timeenvironment will be directed. The Strategy explains thepotential impact of lighting as outlined in the Landscape andVisual Impact Assessment (ES Volume 2), and the designprinciples as outlined in the Design Statement and DesignGuidelines.The SiteAt present the site is under arable cultivation and at the veryedge of Cambridge. There is no lighting as such on site, butthe sky glow from Cambridge is discernable in the night timeskyline.The proposals for development will have a physical impact onthe day time views and considerable impact on the night timeviews.The Guidance Notes for the Reduction of Light Pollutionpublished by the Institution of Lighting Engineers, describes twosources of artificial light pollution, upward reflected light fromthe ground that contributes to sky glow, and light spill whichcontributes to glare and light trespass.There is already considerable light pollution in the area. Thesesources of light pollution have been identified as:• Highway lighting. The busy A1307 lies to the east andthe A1309 to the west which is elevated and therefore thelighting more noticeable. A number of junctions in thearea are well lit and the A1309 junction with the M11 isespecially well lit and because of its elevated positioncreates considerable sky glow. The Park and Ride site atBabraham Road is also noticeable in night time views.• Sky glow: There is considerable sky glow fromTrumpington to the west, Long Road to the north and theNetherhall area to the north east.• The existing CBC complex dominates the night time skyfrom local and long distance views as it creates directlight spill as well as contributing to sky glow.• Shelford Rugby Club: The pitch lighting is visible overlarge distances. It is of high luminance and a very whitelight.ObjectivesThe objectives of the Lighting Strategy are to ensure that theluminance levels proposed for the development are restricted tothe minimum required for safety on the Highway and incidentalareas. Provision will be controlled by the selection of lanternswhich provide efficient design and a minimum amount ofpollution by excessive light flare.The control of light pollution is important for not only the usersof the site, but also nearby residents. It is also important for thebiodiversity of the area, so that light pollution is minimised andhence less potential disruption is caused to the habitats of thedifferent species present.ProposalsDuring construction, work will normally occur in daylight hours,and therefore it is not anticipated that there will be majorartificial lighting requirements. Any external lighting requiredwill be of a temporary nature and task specific. It will also becontrolled to the lowest luminance level required to undertakethe task and ensure work is undertaken in a safe environment.The main development lighting will be designed to beproportionate to safety requirements of the users and complywith relevant European Standards and Codes of Practice. Thesite's lighting will be positioned and orientated to minimize lightspill and excessive upward reflection. Illumination levels andthe specification of luminaries will be controlled to limit the 'halo'effect.The following lighting zones, all of which have differentrequirements, can be identified:• Highways. Lighting to the Highway infrastructure will bein compliance with British Standard BS 5489 to meet theadoptable standard of the local authority. Thesestandards will also apply to roads built to adoptablestandards, but which are not adopted.• Entrances. Entrance zones to buildings will generally belit to a higher level than the surrounding areas – toensure legibility and safety. The principles of entrancedetails are set out in the Design Guidelines contained inthe Design Statement. The detailed design of thiselement will come forward with individual plot design, andguided by the Design Guidelines.• Individual Plots. Lighting in these areas will have avariety of functions. Some architectural features may beenhanced in the dark hours by feature lighting. Suchfeature elements will be very selective and only locatedon key or landmark buildings, to aid evening legibility.Car parking area will be lit to the lowest luminance levelsappropriate to ensure safety, and generally at a low levelso that there is minimum light pollution. Considerationwill be given to switching off lighting during the lateevening and early morning hours where appropriate.36
