Barn Elms Sports

GroundHow we chose the preferred site



Barn Elms Sports Ground

1 Introduction

1.1.1 This note provides further explanation of the process followed and reasonsfor identifying the southern part of Barn Elms Sports Ground as apreferred construction site.

1.1.2 The southern part of Barn Elms Sports Ground has been identified as apreferred location for a shaft site to sequentially drive the construction ofthe main tunnel in both an easterly and westerly direction and toaccommodate permanent structures required to operate the tunnel. The

rationale for this selection is the main focus of this note.1.1.3 In addition, the Barn Elms site has also been identified as the preferred

location to connect the local Combined Sewer Overflow (CSO) known asthe West Putney Storm Relief to the main tunnel. The rationale behindthis decision is detailed as a separate section in this note.

1.1.4 We are currently at the first phase of public consultation and are seekingviews on our preferred sites. We will consider all the feedback we receive

on this and other sites and what amendments to the project may bepossible in response to those comments.

1.1.5 In order to assist consultees in responding to the consultation we set outbelow further information on how the southern part of Barn Elms SportsGround was chosen as a preferred site.

1.1.6 This note is, however, intended as an overview of a lengthy and detailedprocess. We have therefore also provided references to the relevant

reports (available on the consultation website:




needs to merit more detailed consideration. An important consideration isthe need to identify sufficient sites, in the right locations, to enable the

scheme to be built.

2.1.5 The analysis undertaken to date in relation to Barn Elms and other sites inthe surrounding area is summarised below. Initially, this summarydescribes sites we looked at within the London Borough of Richmondupon Thames. It then explains how Barn Elms was assessed againstsites in the relevant neighbouring boroughs to identify a suitable locationfor a shaft site to enable construction of the western section of the main

tunnel and for works to intercept the West Putney Storm Relief CSO.

Long list sites

2.1.6 A preliminary high-level assessment was undertaken of potential maintunnel shaft sites on our long list. Table 2.2 in the SSM sets out theconsiderations used to assess the sites in the long list.

2.1.7 A total of 13 potential main tunnel shaft sites in Richmond were eliminated

at the long list stage and a total of four main tunnel shaft sites identified assuitable for inclusion on the draft shortlist.

2.1.8 Appendix 1 includes details of the assessment of the long list main tunnelshaft sites in Richmond upon Thames.

2.1.9 Two of these sites, those in the foreshore at Lonsdale Road andLondsdale playing fields, were subsequently discounted as they arelocated too far to the west of the area in which a shaft for the construction

of the main t nnel is req ired The estern e tent of the main t nnel is in




2.1.14 The results of the assessment of the draft shortlisted shaft sites inRichmond are summarised in Appendix 2.

2.1.15 In summary, the outcome of the assessment of the draft shortlistconcluded that St Paul’s School playing fields were suitable for thelocation of a main tunnel reception/intermediate site, but that they were notsuitable for a main tunnel drive site. Barn Elms was assessed as suitablefor either a main tunnel drive or reception/intermediate site. For a fullexplanation of the types of site required for the construction of the ThamesTunnel please see the Site Selection: Background Technical Paper,

available on our website .

Assessment of shortlisted shaft sites

2.1.16 Following the assessment of the draft short-listed sites (using Table 2.3 ofthe SSM), the main tunnel shaft sites included on the shortlist aspotentially suitable for the construction of the western section of the tunnelwere:

2.1.17 Main tunnel drive, reception or intermediate sites:

• S17RD: Barn Elms Sports Ground (London Borough of Richmondupon Thames)

• S61WH: Battersea Park, The Parade (London Borough ofWandsworth)

• S68WH: Battersea Park Power Station, Battersea Park Road (London

Boro gh of Wands orth)




• S13RD: St Paul’s School playing fields (London Borough of Richmondupon Thames)

• S08KC: Foreshore, Chelsea Wharf (Royal Borough of Kensington &Chelsea)

• S04WR: Tennis courts and open space, Grosvenor Road (LondonBorough of Westminster)

• S11WR: Large area of foreshore, Millbank/Vauxhall Bridge (LondonBorough of Westminster)

• S18WH: Land off the causeway and adjacent to the River Wandle/BellLane Creek (London Borough of Wandsworth)

• S69WH: Industry/warehouses, Cringle Street (London Borough ofWandsworth

• S72WH: Concrete batching plant and wharf, Cringle Street (LondonBorough of Wandsworth)

• S73WH: Industry/warehouses, Tideway Walk (London Borough ofWandsworth)

• S74WH and S72WH: Industry/warehouses, Tideway Walk (LondonBorough of Wandsworth)

• Safe access: Tunnel lengths during the construction phase should notbe excessive and established safe distances for egress from the

tunnel should maintained.

2.1.21 As a result of the above factors and the distribution of shortlisted maintunnel shaft sites, short-listed sites in the London boroughs of Wandsworthand Kensington and Chelsea, east of the sites in the Battersea ‘zone 5’(see below) are unsuitable for the construction of the western end of themain tunnel.

2.1.22 A Site Suitability Report (SSR) was prepared for each shortlisted maintunnel shaft site containing an assessment of the site having regard toengineering, planning, environment, property and communityconsiderations. Sites were assessed by each discipline as suitable, lesssuitable or not suitable.

2.1.23 Details of the locations of these sites and the recommendations made inthe site suitability reports are provided in Appendix 3. Theserecommendations were taken into account when assessing each site

against the engineering requirements in order to create the preferred list ofmain tunnel shaft sites, as described below.

Creation of the preferred list of shaft sites

2.1.24 Consideration of the main tunnel shaft sites up until shortlist stageprincipally focussed on each as an individual site in isolation from theassessment of tunnel drive and alignment options (i.e. how the tunnel will

Figure 1: Main tunnel shaft site zones

2.1.28 Multidisciplinary workshops were held to identify the most suitable maintunnel shortlisted site within each zone, taking into account theconclusions reached in the Site Suitability Reports, as described aboveand in Appendix 3. As a consequence, the following sites were identified

as the most suitable for their respective zones:

• Reception/intermediate shaft site for Zone S1 – Hammersmith area:S33HF Hammersmith Pumping Station.

• Main drive, reception or intermediate site for Zone S2 – Barn Elmsarea: S17RD Barn Elms Sports Ground.

• No preferred reception/intermediate shaft sites were identified in Zone

due to barge loading and movement constraints in this busy section ofthe river;

• The size of site required for a double drive at Tideway Walk wouldsignificantly conflict with regeneration aspirations for the Nine Elmsarea;

• Extensive use of land at Tideway Walk would have a very high landacquisition cost;

• A larger number of existing occupiers at Tideway Walk would need to

be relocated;

• Barn Elms Sports Ground, although designated as Metropolitan OpenLand and public open space, could accommodate a drive shaft withoutcausing unacceptable conflict with planning policies due to the extentof remaining open space and number of facilities on the site; and

• Even if the Tideway Walk site was used as a double drive site, aworksite would still be required in the Barn Elms area to connect theWest Putney Storm Relief CSO to the main tunnel.

Identification of the preferred site to intercept the WestPutney Storm Relief CSO

2.1.32 At the same time as assessing potential sites for the construction of themain tunnel, sites were also assessed for the interception of the CSOswhich need to be connected to the main tunnel.




Draft shortlist sites

2.1.38 The 12 potential sites for the interception of the West Putney Storm ReliefCSO and its connection to the main tunnel which were included on thedraft shortlist and assessed at this stage were:

• C05XA: Foreshore

• C05XB: Woodland area between embankment and Barn Elms

• C05XD: Small business for boat repairs, Leader Gardens

• C05XE: Leader Gardens• C05XG: Area fronting block of flats in Home Way (Jay House)

• C05XH: Area fronting block of flats in Home Way (Lancaster House)

• C05XK: Area fronting block of flats in Home Way (Huntingford House)

• C05XM: Area fronting block of flats in Home Way (Pearson House)

•

C05XN: Area fronting block of flats in Commondale• C05XP: Area fronting block of flats in Commondale

• C05XQ: Barnes Common (Barn Elms Sports Field)

• C05XR: Area fronting block of flats in Commondale

2.1.39 The results of the assessment of the draft shortlist sites for the interceptionof the West Putney Storm Relief CSO are summarised in Appendix 5.




C05XQ as the preferred site can be found in the Preferred Scheme Report .

2.1.44 Site C05XQ was considered to be a good-sized, flat site that would allowsafe, efficient working. Importantly, the site is considered suitable from anengineering, planning, environment and property perspective, although itwas considered less suitable from a community perspective because ofthe loss of open space. However, it is recognised that the site is a smallerpart of a much larger area of open space.

2.1.45 The site would offer a separation distance from Leaders Gardens and

adjacent residential properties which, in conjunction with appropriatemitigation measures, would reduce potential impacts of construction noiseand dust on the surrounding community. The established trees alongBeverley Brook would also provide visual screening from the gardens andadjacent properties to reduce the impact on the visual amenity of the area.The temporary loss of public amenity space, relative to the overall size ofthe Barn Elms School Sports Fields, would be less and have a reduced

impact when compared with works in site C0X5E.2.1.46 Vehicle access to site C05XQ was assessed as good as there is potential

for direct access to the strategic road network via a dedicated temporaryhaul road.

2.1.47 The site would allow all works for the drop shaft and interception chamberconstruction to be carried out within the sports field site. This is preferredto the other sites, which would require interception works external to the

CSO d h ft it




community concerns about the loss of public space and the traffic andenvironmental impacts that need to be mitigated.

3.1.2 If the site is confirmed in due course as the selected site, it would – withthe rest of the scheme – be the subject of a statutory EnvironmentalImpact Assessment (EIA) that would identify all environmental concerns,necessary mitigation and conclude on the extent of environmental impactsafter mitigation measures have been taken into account. The decision-maker for the scheme would, when deciding whether or not to grantplanning permission (development consent), take into consideration the

conclusions of the EIA.3.1.3 As mentioned above, we are currently in our first phase of consultation

and will listen and take into consideration all comments made about ourproposals.

3.1.4 If new information emerges which requires us to revisit our assessment ofthe Barn Elms Sports Ground site and/or any other sites, we will do this(and undertake a targeted repeat of the site selection process where

necessary).

3.1.5 We will work very closely with the local boroughs, local residents and otherinterested groups to minimise both the construction and permanent impactof the works.

3.1.6 Further consultation will allow stakeholders, including the public, tocomment on any amendments we have made to the scheme in responseto Phase One consultation.

4.1 Assessment of shortlisted sites

4.1.1 Seven sites were included on the draft shortlist as potentially suitable foruse as main tunnel drive sites for the construction of the western sectionof the tunnel.

4.1.2 A Site Suitability Report (SSR) was prepared for each of these sites

having regard to engineering, planning, environment, property andcommunity considerations. Sites were assessed by discipline as suitable,less suitable or not suitable. A summary of the conclusions of eachdisciplines assessments is provided below. These recommendations weretaken into account when assessing each site against the engineeringrequirements in order to create the preferred list of main tunnel shaft sites.

4.1.3 The site’s suitability was assessed for a main tunnel drive shaft, anintermediate/reception shaft and a main tunnel drive shaft with CSOinterception. The following is a summary of the conclusions of eachdisciplines assessment.

4.1.4 Engineering: Assessed the site as suitable for use as a main tunnel driveshaft, intermediate/reception shaft and main tunnel drive shaft with CSOinterception. This was predominantly due to the good site size, river

access and good access to the local road network.

4.1.5 Planning: Assessed the site as suitable for all types of shaft. There are aseries of planning designations that are applicable to the site. However, itwas felt that potential impacts or conflicts with policy could be mitigated forand that potential additional disruption of main tunnel drive shaft with CSOconnection could be balanced out by potential for more effective andefficient use of the land via the need for only one site for both construction

and interception works instead of two.4.1.6 Environment: Overall, the site was assessed as suitable for all types of

shaft. The site was considered likely to be suitable from the perspective oftransport, hydrogeology, surface water, built heritage, townscape, floodrisk, noise, air quality and land quality. However, the site is less suitablefrom the perspective of ecology and archaeology.

4.1.10 Engineering: Assessed the site as suitable for use as a double drive maintunnel shaft, main tunnel drive shaft and intermediate/reception shaft.This was predominantly due to the good site size and the potential forgood river and road access.

4.1.11 Planning: Assessed the site as not suitable for either a double or singledrive main tunnel shaft. The scale of the development and the land-takeassociated with both the double and main shaft sites is considered to betoo great for this sensitive location, which is subject to a number of policydesignations. The site was assessed as less suitable for anintermediate/reception shaft given the reduced scale of constructionactivity and permanent land take.

4.1.12 Environment: Overall, the site was assessed as less suitable for either adouble or single main tunnel shaft or an intermediate/reception shaft. Thesite was considered suitable from the perspectives of transport,archaeology, water resources, flood risk, air quality, noise and land quality.However, the site is less suitable from the perspectives of built heritageand townscape and ecology.

4.1.16 Engineering: Assessed the site as less suitable for use as either a maintunnel drive shaft or an intermediate/reception shaft for a variety ofreasons including the presence of Battersea Power station restricting sitetraffic, potential problems with contaminated land and the presence of

numerous underground structures.

4.1.17 Planning: Assessed the site as less suitable for a main tunnel drive shaftas works would result in significant land-take across the site andsubstantial construction activity, both onsite and in the river. The level ofconstruction activity would reduce the potential to redevelop the site inparallel with other uses, which could cause delay or even hinder thepotential for regeneration. The site was assessed as suitable for an

intermediate/reception shaft as the small site size required for anintermediate shaft site may make it possible to implement regenerationproposals alongside the use of the site for the Thames Tunnel Project.

Disadvantages:Site located wholly within an ArchaeologicalPriority Area, although site ispart of a larger designation so

mitigation may be possible. Designated green chainsand linksrunsthrough the site, may be possible to mit igate by re-routing

link or adjusting area of CSO site if possible. Site isdesignatedasMetropolitan Open Land, although site ispart of a larger

designation and therefore it may be possible to mitigate for use

of site. Scout Hut ispartially on-site and partially adjacent tosite, may be possible to mitigate by altering site boundary as

site area islarger than required for a CSO site.

Recommendation:There are a number of designationsthat

Site_ID Site Name Proximity to sensitive receptors Social c onsi derations Economic c onsi derati ons Health c onsi derati ons Equal ity c onsi derati ons Commentary on community considerations Assessed by

C05XA Foreshore As the site is in the foreshore of the

Thames, there are fewsensitive receptorsin its vicinity.

The ThamesPath with itsbenchesis likely

to be valued as a space for socialinteraction. A Scout Hall, also likely to play

a role in community cohesion, islocated to

the northwest corner of site (and oppositesite). Disruption the ThamesPath and

Scout Hall may affect community

cohesion.

No indication of any impact on the local

economy.

The ThamesPath isl ikely to be valued as

a space for exercise and relaxation. AScout Hall, also likely to have a

recreational value, islocated to the

northwest corner of site (and opposite site).Disruption the ThamesPath and Scout Hall

are likely to affect health and well-being.

There isno indication of a specific impact

on equality groups.Advantages:There are no significant built facilities

on-site and no evidence to suggest disproportionateimpact on one or more equality groups.

Disadvantages:The ThamesPath and the Scout

Hall may be disrupted, thereby impacting on

community cohesion and health and well-being.

Recommendation:The site issuitable from a

community impactsperspective, with mitigation toaddressdisruption to the ThamesPath and Scout

Hall.

RS

C05XB Woodland Area between Embankment and Barn Elms. The site iswithin proximity to large

gardensand a play area, although thisislocated around 110m away and istherefore

unlikely to be affected.

There ispotential for partial lossof and

disturbance to the open space on-sitewhich may be valued by the local

community. Usersof the footpath running

adjacent to site may also be affected. Thesite islocated opposite the Barn Elms

School SportsCentre grounds(to the westof the proposed site), which could i mpact

on leisure and recreation activitiesand

therefore impact on community cohesion.There isa Scout Hall located to the north

of proposed site, slightly on the top corner

of the site, and a Sea Cadet Corpsbuildingopposite the site, these club buildingsare

likely to be valued for social interaction.

Use of thissite is likely to affect the local

economy.

There may be an affect on health and well-

being due to potential partial lossof openspace and the proximity of the Thames

Path and Barn ElmsSchool SportsCentre

groundswhich may be valued for exerciseand recreation. The Scout Hut and Sea

Cadet Corpsare also likely to be used forrecreation activitiesand could also be

affected by the use of the site.

There isa Scout Hut and a Sea Cadets

building opposite the site, young peopleare likely to meet here and therefore there

may be an impact on equalities groups.

Advantages:There are unlikely to be impactson the

local economy.

Disadvantages:The usersof the ThamesPath,

Barn Elmssports ground and on the Scout Hut andSea Cadet Corpsmay be disrupted so may affect

community cohesion and health and well-being.There may be a higher impact on young people who

use the Scout Hut, the school sportsgrounds and the

Sea Cadetscentre.

Recommendation: There are a combination of

sensitive receptors, but thissite may have potential

from community point of view, subject to

investigating the level of i mpact on Sea Cadet CorpsHQ, the Scout Hut, Thames Path, open space and

recreation area adjacent to the site.

There ispotential for disturbance to open

space and usersof the Thames Path whichrunsadjacent to the site. The site itself has

a Sea Cadet Corpsbuilding and boat repairyard on site which may be valued by thelocal community and may be lost through

the use of the site. The site islocated

opposite large gardenswith sportsandrecreation activitiesand with potential

value for community cohesion.

The impact or lossof a small businessf or

boat repairson the site, may have anaffect on the local economy.

There ispotential for impactson health

and well-being due to the proximity of theThamesPath and open space which may

be used for exercise and relaxation.

There isa Sea Cadetsbuilding on the site

which may be lost through the use of thesite. Young people are likely to meet here

and therefore there may be some affect onthisequality group.

Advantages: There are no significant advantages

from a community impactsperspective.

Disadvantages: There issome potential impact onsensitive receptorson the site asthe Sea Cadetsbuilding and a small boat repair businessmay be lost

through the use of the site. The site may i mpact on

the ThamesPath adjacent to the site and on theopen space in proximity to the site which affect

community cohesion and health and well-being. Inproximity to the site there are gardens, tennis courts

and a play area which could be impacted too. There

are potential impactson young people using theScout Hut and the Sea Cadetsbuilding on the site.

Recommendation: There are a number of cumulativeimpacts, including potential lossof a Sea Cadets

centre boat repair businesson the site. However, it

may be possible to mitigate the affectsif the CSOsite is located in the western point of the boundaries,

which would be the area furthest away from the SeaCadet CorpsHQ.

RS

C05XE Park There is high density residentialdevelopment adjacent to and opposite to

site. The site isin proximity t o several

community facilities, namely a Sea CadetCorpsbuilding, the Imperial College Boat

Club, the ThamesRowing Club, a furtherboat club and a boat house.

There ispotential for impact on communitycohesion given that site islocated on

public open space with facilities including

tenniscourts, gardensand a play area.The ThamesPath also runsadjacent to the

site. These facilitiesmay be used as spacefor social interaction and may be of value

to the local community.

There are unlikely to be impactson thelocal economy through the use of this site.

There ispotential for impact on health andwell-being due to potential lossof public

open space, tenniscourts, gardensand a

play area on-site. The ThamesPath alsorunsadjacent to the site. These facilities

may be used for exercise and relaxation.

There ispotential for impact on youngpeople who may use the playground on the

site and may engage in sportsand leisure

activities on and in proximity to the site.

Advantages:There isunlikely to be any impact on

the local economy.

Disadvantages:There ispotential for impact on a

large number and wide variety of sensitive receptors

due to public open space, tenniscourts, gardensandplay area on site. These facilitiesmay be valued by

the local community as space fro social interaction

and asplaces for exercise and relaxation. There mayalso be impactson young people using the

playground or park facilities.

Recommendation:The site isgenerally lesssuitable

from a community point of view, due to a largenumber of sensitive community receptorson-site,

adjacent to the site and within the immediate vicinity

of the site. However, it is a large park, so may beable to mitigate the affectsif the CSO site issited in

an area of the park that is not widely used for sportand recreation purposes.

RS

C05XG Area front ing block of f la ts in Horne Way There ishigh density res ident ial area inproximity to the site, including a block of

flats to east and five terraced dwellingstosouth. There are further flatswithin

proximity to site to the east and west, but

separated from the site by roads. There isa playground within the vicinity of the site

(approximately 60m away).

The site is amenity space associated withthe adjacent residential area, the potential

lossof this space may impact on the localcommunity.

There are unlikely to be impactson thelocal economy through the use of this site.

There are unlikely to be impactson healthand well-being from the use of thissite.

There isa playground approximately 60mfrom the site, children using this

playground are unlikely to be affected bythe use of the site due to the distance from

the site.

Advantages:No indication at thisstage of impact on

the local economy, health and well-being or

equalitiesgroups.

Disadvantages:Some potential impact on sensitive

receptorsdue to close proximity of the site toresidential flats. There is a playground located within

vicinity of site but not close enough to significantlyimpact any children using thisfacility.

Recommendation:The site haspotential from a

C05XH Area front ing blocksof f lats in Horne Way There ishigh densit y resident ial area in

proximity to the site, including immediatelyadjacent to the site. The site is surrounded

by flatson three sidesso there issomepotential impact on sensitive receptors.

The site is amenity space associated with

the adjacent residential area, the potentiallossof this space may impact on the local

community. There isa playground oppositesite (approximately 40m away) but thisi sseparated by a road and a block of flats

and istherefore unlikely to have significant

impact on community cohesion.

There are unlikely to be impactson the

local economy through the use of this site.

There are unlikely to be impacts on health

and well-being from the use of thissite.

There isa playground approximately 40m

from the site, children using thisplayground are unlikely to be greatly

affected by the use of the site due t o thepresence of a road and flatsseparating theplay area from the site.

Advantages:The blocksof flats immediately

adjacent to the site could provide a buffer aff ect toreduce impact on the local playground. There isno

indication at thisstage of impact on local economy,health and well-being or equalitiesgroups.

Disadvantages:There isa high density block of flats

adjacent to site to the north, and two other blocks to

the east and west of the site, so there ishigh

potential for impact on local residents. The potentiallossof amenity space for the adjacent flats isl ikely to

impact on the local community.

Recommendation: The site haspotential from a

community point of view, subject to the extent ofimpact on the local residential area. Due to the site

being surrounded by flatson three sides, the CSO

would be best placed south of site where there wouldbe lessimpact on the community.

The site isamenity space potentially with

numerousundefined users, but would besubject to further investigation at thisstage

of assessment.

There isa church located within the vicinity

of the site, faith groupsusing the churchare unlikely to be affected given the

presence of a road and several buildings

between the two, providing a buffer.

Advantages:There are unlikely to be any impacts

on the local economy. Three sidesof the site aresurrounding by a road which islikely to act as a

buffer between site and residential development.

Disadvantages:High density residential blocks

surround the proposed site in most cases these areseparated by a road, although one block isadjacent

to the site. The open space on the site may be used

by the residents, lossof this open space could impacton community cohesion and health and well-being i f

the area isused for exercise or relaxation. There isa

bowling green and pavilion close to the site and achurch located to the south of the site but, due to the

buffer effect of t he road and flat blocks, any impactson these facilitiesare unlikely to be significant.

Recommendation:Due to the high density of

dwellingssurrounding the site, thissite is less

suitable from a community point of view. However,

thisi ssubject to investigating howthe open space isused and whether the CSO site would disrupt its

current use.

Footpathsalong Beverley Brook may also

be affected by use of the site. There islikely to be some impact on health and well-

Lossof open space on site may affect

children and young people, aswell as anyother equality groupsusing the open

space.

Advantages:A large open space with a small

number of sensitive receptorswithin proximity of site.Beverley Brook (with possible tree cover to mitigate

visual impact) separatessite from high density flats,

reducing potential impact. Thisi sa large open spaceand some areasprobably being lesswidely used than

others, so there ispotential for placing a CSO sitehere.

Disadvantages:The site islocated on public open

space with sportscentre facilities. However, degree

to which the proposed site is being used isuncertain -

at the next stage, establish use levelsof site. Due topotential lossof open space and disruption to

surrounding open space, community and sportsfacilities and the ThamesPath, impactson

community cohesion, health and well-being and

equality groupsare likely.

Recommendation:Although there may be multiple

impacts, the site doeshave potential from acommunity point of view, subject to an investigation

into howthe space is currently being used. The site islarge so there could be areasmore suitable for CSO

sitesthan others (with lessrecreation / accessuse /

potential visual impact etc.)

The site is currently open space which may

have amenity value to local residents.There iscurrently a path running through

the site which linksto the hospital, change

site, any potential impact islimited.

Advantages:Thisis a large open space and isl ikely

to have some areasless widely used than others, so

there ispotential for use as a CSO site on part of the

open space. Young people from nearby schoolsareunlikely to be negatively impacted due to the open

space, road and residential dwellingsproviding abuffer from the site.

Disadvantages:There may be some impact on the

dense residential terraced housesand flatst o the

east of site. The loss of some open space/common

land plusproximity to the public house may havesome affect on community cohesion and health and

well-being.

Recommendation:Due to the large combination of

sensitive receptorsin proximity this site islesssuitable from a community point of view.
