Case No: 20/00650/FUL

Proposal: FORMATION OF A DRAINAGE POND FOR THE ATTENUATION OF SURFACE WATER RELATING TO DEVELOPMENT AT FORMER RAF UPWOOD AND UPWOOD HILL HOUSE

Location: LAND SOUTH OF UPWOOD HILL HOUSE AND FORMER RAF UPWOOD, RAMSEY ROAD, BURY

Applicant: EVERA HOMES LLP C/O SAVILLS (UK) LTD (MRS LYNETTE SWINBURNE)

Grid Ref: E: 527481 N: 283200

Date of Registration: 02.04.2020

Parish: WISTOW

RECOMMENDATION - APPROVE

This application is referred to the Development Management Committee (DMC) as the proposed development represents a departure from the Development Plan.

1. DESCRIPTION OF SITE AND APPLICATION 1.1 This application relates to a parcel of agricultural land located to the south of Ramsey Road, on the southwest periphery of the village of Bury. The southern boundary of the former RAF Upwood site is located approx. 43m to the north of the main body of the application site.

1.2 The application site is located in the countryside and comprises approx. 8.7ha of Grade 2 Agricultural Land which slopes down from north to south. The application site lies within Flood zone 1 of the LPA’s Strategic Flood Risk Assessment maps. 1.3 The application seeks planning permission for the formation of a drainage pond for the attenuation of surface water relating to development at Former RAF Upwood and Upwood Hill House. The proposed drainage pond measures approx. 221m in length and approx. 67m in width at its largest point.

1.4 Incorporating a maximum depth of approx. 2.45m, the proposed attenuation pond will hold approx. 21,462m3 of water. Noting the variance in topography across the site and with reference to the Reservoir Act 1975, approx. 3813m3 of water will be held above the natural level of the surrounding land (which falls away to the south).

1.5 There is no built form immediately adjacent to the main body of the application site aside from Ramsey Road. Whilst the nearest residential unit (25 Canberra Road) is located approx. 26m from the northwest corner of the application site, it is noted that the drainage pond would be located approx. 127m to the southeast of this property.

2. NATIONAL GUIDANCE 2.1 The National Planning Policy Framework (19th February 2019) (NPPF 2019) sets out the Government’s planning policies for England and identifies three overarching objectives (economic, social and environmental) to be pursued in mutually supportive ways in order to contribute to the achievement of sustainable development.

2.2 Paragraphs 10 and 11 of the NPPF 2019 identify a presumption in favour of sustainable development. Planning Practice Guidance is also relevant and a material consideration.

4.2 20/00161/REM: Reserved Matters application for the approval of layout, scale, appearance and landscaping (including the discharge of condition 20) for the development of 160 new dwellings at RAF Upwood and Upwood Hill House, Ramsey Road, Bury.

Approved 02.09.2020

4.3 20/00683/FUL: Erection of a bat barn with associated landscaping.

Approved 16.07.2020

5. CONSULTATIONS 5.1 Bury Parish Council: Comments awaited – an update will be provided in the Late Reps document

Cambridgeshire County Council as Lead Local Flood Authority: “Based on [the revised documents], as Lead Local Flood Authority (LLFA) we can now remove our objection to the proposed development.

Cambridgeshire County Council Highways: I note that the end attenuation pond will be managed and maintained by AWA which is acceptable in relation to the highway drainage of the site. I assume that the flood and water team will also be consulted. The C.E.M.P that has been submitted indicates wheel washes will be incorporated into the scheme which is acceptable. But there are various other details that should be submitted below:

• Details of construction traffic associated with the scheme in both number and types of vehicles expected. • Details of the construction access (Geometry etc.) that will be used and the maintenance access that will be used (suitable for the largest vehicle that will use the site). • Locations of wheel wash stations • Onsite parking and turning details. • Routes for construction vehicle to the site. • Any signage that will be required.

Officer comment:

It must be noted that the Flood Risk Assessment (BWB Consulting: July 2013 – NTH051/FRA Rev E) which accompanied 1201274OUT indicated that the attenuation pond may be adopted by AW as part of the S104 process. At the time of writing, confirmation from Anglian Water on this point has not been received – an update will be provided in the Late Reps document. All of the “other details” outlined in CCC Highways comments are adequately covered in the revised CEMP (GEDA Construction: 01/07/20) with the exception of the numbers and types of vehicles expected. In this regard, the Agent for the application has confirmed that approx. 4200 vehicle movements will be required during the construction of the proposed attenuation pond but the exact specification of the vehicles involved in the excavation and removal of material are unknown at the time of writing. The revised CEMP outlines that deliveries to the site will seek to avoid the peak hours of 0830-0930 and 1700-1800, sufficient parking and manoeuvring areas will be accommodated within the site and the vehicles leaving the site will turn left onto Ramsey Road. With the imposition of a condition to ensure that the proposed development accords with the provisions of the revised CEMP, the proposed development is considered to be acceptable in this regard.

Natural England: No objection raised

Anglian Water – No comments received to date. Any update will be provided in the Late Reps document.

No response received from:

• Cambridgeshire County Council Archaeology • Cambridgeshire Wildlife Trust • Environment Agency • Middle Level Commissioners

6. REPRESENTATIONS 6.1 None.

7. ASSESSMENT 7.1 The main issues for consideration are:

• The principle of development • Biodiversity/Ecology • Design • The impact on amenity • Highways

Background

7.2 The former RAF Upwood site is an allocation (RA8) within Huntingdonshire’s Local Plan to 2036 (HLP 2036) for mixed use development. Phase 1 comprises an Outline planning permission for the redevelopment of the former RAF Upwood site (approved under 1201274OUT) and the matters reserved from the outline planning permission (20/00161/REM) which were approved 02.09.2020. Plans for Phase 2 are yet to be submitted to the LPA.

7.3 The principle of an attenuation pond in this area was established through the 1201274OUT approval. Although in a similar position, the proposed attenuation pond is larger than that which was previously approved as the design has been engineered to attenuate flows from both Phase 1 and Phase 2; the original pond design was only to accommodate Phase 1 given the allocation of RA8 with a higher number of residential dwellings was not adopted at that time. In accordance with paragraph 165 of the NPPF, condition 25 of 1201274OUT requires full details of the sustainable drainage system to be approved prior to any development which will create surface water run-off. This condition remains to be discharged at the time of writing.

The principle of development

7.4 Whilst connected to the drainage for the Former RAF Upwood allocation, the application site does not fall within the site boundary of the allocation and is therefore located in the countryside. Policy LP10 of HLP 2036 outlines that development in the countryside will be restricted to the limited and specific opportunities as provided for in the relevant policies of HLP 2036, noting that the purpose of LP10 is to ensure that development protects the resources and recognises the intrinsic character of the countryside. Policy G1 of the Bury Neighbourhood Plan (BNP) adopts a similarly restrictive position. As such, the conflict between the proposed development and polices LP10 of the HLP 2036 and G1 of the emerging Bury Neighbourhood Plan is recognised.

7.5 Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires applications for planning permission to be determined in accordance with the Development Plan unless material considerations indicate otherwise. The remainder of this report will provide an assessment of the relevant material considerations.

7.6 The proposed attenuation pond has been designed to attenuate flows from both Phase 1 of the re-developed former RAF Upwood site (approved under 1201274/OUT and 20/00161/REM) and Phase 2 of the scheme which is yet to be submitted to the LPA but will comprise the remaining land within the boundaries of the RA8 allocation. As such, the proposed development is considered to represent an integrated approach to sustainable drainage across the whole of the RA8 allocation.

7.7 Whilst the proposed development does not fall into any of the categories of development which are directly supported by LP19, LP20, LP23, LP27, LP28 or LP33, due regard is given to the supporting text of LP10, which states that a “balance must therefore by struck between […] providing opportunities for communities to achieve local development aspirations, with protecting the character of existing settlements and recognising the character and beauty of the surrounding countryside”. It is also noted that a smaller pond was approved in this location as part of the outline consent (1201274OUT).

7.8 With reference to paragraph 4.113 of HLP 2036, given the scale and nature of the proposed development the proposal is not considered to adversely affect the character and tranquillity of the countryside, nor reduce opportunities for others (including wildlife) to use and enjoy the countryside.

7.9 Although the proposed development is located in the countryside, the location is considered to be justified having regard to the fallback position of the smaller drainage pond, and the functional relationship of the development with the delivery of allocation RA8 of HLP 2036 - approximately 450 dwellings and 2ha of B1 employment land. The Planning Balance section of this report evaluates the degree of conflict with the Development Plan and the relevant material considerations.

Biodiversity/Ecology

7.10 The application site comprises a parcel of Grade 2 agricultural land. Whilst the processes associated with agricultural practice tend to reduce the ecological potential of land when compared to a parcel of ‘unworked’ land, the diversity and complex interactions of the ecosystem within the application site must be recognised and the parcel of land afforded a moderate to high biodiversity value. 7.11 The proposed development would result in the removal of a significant parcel of land from agricultural use, however the use of the land around the application site would not be impacted by the proposed development and would remain available for agricultural use. Whilst the biodiversity value of agricultural land is recognised, the proposed development would allow for the introduction of a new and varied ecosystem.

7.12 New planting is identified on the submitted soft landscaping plans ((96)010 Rev E and (96)011 Rev E) which incorporates a diverse mix of aquatic/wetland specific plants and native species which will benefit and attract pollinators. The introduction of a body of water is also likely to provide a habitat for amphibious wildlife, along with feeding and foraging areas for bats, birds and invertebrates.

7.13 With reference to the criteria outlined in LP30 of HLP 2036, the proposed development would not result in an adverse impact upon a site of national, regional or local ecological importance, nor would a priority habitat or species be unacceptably impacted. The proposed development represents a new biodiversity feature which may help reverse the decline of certain species, contributes toward the provision of multi-functional green infrastructure across the district as a whole and delivers a net gain with regard to biodiversity value.

7.14 In addition, policy LP3 (c) of HLP 2036 states that a proposal will be supported where “consistent with the objectives of the Cambridgeshire Green Infrastructure Strategy (2011)”. The Cambridgeshire Green Infrastructure Strategy outlines that Green Infrastructure includes bodies of water within the multi- functional rural and urban network. Whilst the proposed development will not offer public access, the habitat potential/ecology benefits of the proposal must be considered alongside the positive impacts of water storage and the slowing down of run-off into nearby watercourses.

7.15 In this instance, the proposed development is considered to avoid any adverse impacts on biodiversity/geodiversity and is acceptable with regard to policies LP2, LP3 and LP30 of HLP 2036, policy G2 of BNP and the direction of paragraphs 170 and 174-175 of the NPPF.

Design

7.16 The overall design of the proposed attenuation pond is considered to accord with the principles of the Cambridgeshire Flood and Water SPD 2107 and has been amended in line with the advice from the LLFA.

7.17 The proposal retains the overall principles and drainage strategy approved under 1201274OUT. The LLFA offered no objection to the revised proposal noting that the submitted hydraulic calculations demonstrate that the system will have sufficient capacity to accommodate flows from both phases.

7.18 The proposed attenuation pond includes a ‘fore bay’ to allow suspended silt within the surface water to settle out. This feature will provide a two stage Sustainable Drainage System (SuDS) treatment for surface water within the pond. Once water has moved through the pond, it will discharge to a newly cut ditch/swale connecting into the existing land drainage network and ultimately Bury Brook/High Lode downstream of the site at a rate of approx. 22.4 l/s during all events up to and including a 1 in 100 year flood event plus a 40% allowance for climate change.

7.19 Where a proposal involves a discharge to a watercourse which is the responsibility of the Environment Agency, criteria (c) of Policy LP15 of HLP 2036 requires the details of the discharge to be agreed with the Environment Agency. In order to ensure that this detail is addressed, a condition requiring confirmation of the discharge rate with the Environment Agency will be imposed. With the imposition of this condition, the proposed development is considered to be acceptable with regard to policy LP15 of HLP 2036 and policy ISF4 of BNP.

The impact on amenity

7.20 Due to the nature of the proposal, the proposed development is not considered to negatively impact the amenity of the residential units to the north with regard to overlooking, overshadowing or by way of being overbearing.

7.21 Whilst some disturbance may arise from the movements and noise associated with the formation of the attenuation pond, the separation distance between the application site and the nearest residential units must be taken into account, along with the fact that these impacts will be temporary. The submitted Construction Environment Management Plan (CEMP) includes provisions for wheel washing, dust suppression, hours of working, requirements for delivery of materials and their storage, speed limits and signage along with details of access for vehicles and construction teams. These details will be secured by condition.

7.22 Subject to the imposition of this condition, the proposed development is considered to be acceptable with regard to policy LP14 of HLP 2036, policy G2 of BNP and paragraph 127 of the NPPF.

Highways

7.23 The previously approved application for a bat barn (20/00683/FUL) secured the details of the required access from Ramsey Road to the application site. The approved plan (100- 001/075D) from 20/00683/FUL identifies that a temporary access route (measuring approx. 3.5m in width and approx. 350-400mm deep) from Ramsey Road to the gate which encloses the track to the application site will be created using recycled 6F2 material, or crushed material from the demolished buildings of the Former RAF Upwood site. A condition will be imposed to secure an appropriate timeframe for the removal of the temporary access.

7.24 In terms of future movements associated with the attenuation pond, the Agent has confirmed that de-silting will be required, initially at six monthly intervals and then on a five-year cycle as required. As this activity will be undertaken by a JCB-type excavator with off-road capability and landscaping maintenance would be unlikely to comprise of any machinery heavier than mowing equipment, an access track which encircles the entire pond would be superfluous.

7.25 The anticipated frequency of the anticipated maintenance visits is not considered to represent a detrimental impact upon the safety of the highway and is acceptable in this regard. Whilst the temporary construction route will be removed and no parking provision adjacent to the attenuation pond is proposed, visitors to the site will be able to utilise the existing highway access and hardstanding area. This arrangement is considered to be acceptable.

Conclusion and Planning Balance

7.26 Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires applications for planning permission to be determined in accordance with the Development Plan unless material considerations indicate otherwise. The proposal conflicts with the Development Plan as the site is located within the countryside, is not allocated for development within the Development Plan and does not fall within the “limited and specific opportunities” provided for in policy LP10 of HLP 2036.

7.27 The main body of this report provides an assessment of the material considerations relevant to the proposed development. Of particular importance is the need for the attenuation pond to serve the full development allocated (RA8) within HLP 2036.

7.28 The NPPF has at its heart the presumption in favour of sustainable development. To be sustainable, development must, as noted in paragraph 6 of the NPPF, strike a satisfactory balance between the economic, environmental and social considerations.

7.29 In terms of the economic dimension of sustainable development, the proposed development would make a minor contribution towards economic growth during the construction/maintenance phases.

7.30 With regard to the environmental dimension of sustainable development, the proposed development is considered to provide a net gain in biodiversity value as the positive impacts arising from the introduction of a new, complex ecosystem are considered to outweigh the loss of the parcel of agricultural land.

7.31 The social dimension of sustainable development is considered to be satisfied as the proposal seeks to enable the management of surface water from the entirety of the RA8 allocation via a single, comprehensive strategy.

7.32 All the material considerations have been fully considered and the application is recommended for approval.

8. RECOMMENDATION - APPROVAL subject to conditions to include the following • Time limit • Development to be implemented in accordance with the approved plans • Accordance with the submitted Construction Environment Management Plan (CEMP) • Submission of confirmation from the Environment Agency and/or Middle Level Commissioners that the discharge from the attenuation pond is acceptable • Submission of a hard and soft landscaping implementation and management scheme • Submission of details regarding the management/maintenance of the attenuation pond • Full details of how the land will be restored following the removal of the temporary access from Ramsey Road which serves the application site, along with a timetable for the works

All trees and shrub areas to be watered to field capacity in periods of drought All tree and shrub areas to receive an application of slow release fertilizer applied in accordance with the manufacturer's instructions and any mulch to be replaced/ replenished to previous specified levels at the end of the rectification period At the end of the rectification period all trees and shrub areas shall be inspected and any specimens found to be dead or failing shall be replaced with stock to the original specification Wildflower seeding generally: Cut once a sward height of 100mm is reached and thereafter cut four-five times in the latter half of the first year and two-three times during the second year Track of establishment to reduce the pernicious weed content to a height of approximately 40-60mm. Arisings to be removed to a predetermined facility - All areas to be maintained as litter free ONGOING MAINTENANCE AND MANAGEMENT On completion of the 12 month maintenance period a site inspection shall be undertaken by the landscape contractor, landscape architect/ client and a representative of the appointed management company as necessary, to ascertain that all areas of communal landscaping associated with the development are in a satisfactory condition for handover to the management company. Any necessary works shall then be carried out to the satisfaction of the landscape architect/ client to enable the works to be handed over to the appointed management company or Local Authority as appropriate. GENERAL PRINCIPALS - All trees, shrub and hedgerow plantings to be checked regularly for damage or disease and any problems addressed. Consideration should be given to the removal of stakes and ties after approximately five years or as appropriate. - Wildflower areas to be check for nutrient build up and for diversity of sward. Remediation measures to be taken including overs owing and selective weeding as necessary to avoid over incursion/growth of grass species and docs etc- areas to be patch repaired as necessary. In second and subsequent years following sowing: Emorsgate EM10 Areas of Tussock grass generally to be managed as meadow, with a main summer cut after July/ August flowering, in combination with autumn and possibly spring mowing if required. Leave the cut 'hay' to dry and shed seed for 1-7 days prior to removal. Emorsgate EW1 If required, before trees have matured, woodland mixture seeding to receive annual mid summer cut to prevent dominance of grasses, nettles and brambles. Once tree coppice areas are established, area should required little management. see drawing (96)010 for continuation Emorsgate EP1, EM8 & EG8 Soft Landscape Key Variations in structure to continuously submerged areas can be achieved by cutting back Soft Landscape Schedule and removing short sections of vegetation every 2-3 years in rotation, between September and November.
