FLOOD RISK ASSESSMENT FOR NEW DEVELOPMENT

1 Development description and location 1 a. What type of development is proposed and where will it be located? Include whether it is new development, an extension to existing development or change of use etc. The proposed development is a new residential development located within the settlement boundary of Burton upon Trent. The site location plan is included within Appendix A of this report.

1 b. What is its vulnerability classification? The highest vulnerability classification in the proposed development is the ‘More Vulnerable’ residential development in accordance with Table 2 of Technical Guidance to the NPPF.

1 c. Is the proposed development consistent with the Local Development Documents? The site is currently white land within the Burton on Trent settlement boundary.

1 d. Please provide evidence that the Sequential Test and where necessary the Exception Test has been applied in the selection of this site for this development type? The Sequential and Exception Tests can be found in Appendix E of this report.

2. Definition of the flood hazard 2a. What sources of flooding could affect the site? (see annex C PPS25). 1. Fluvial (discussed in Section 18) 2. Ground water (discussed in Section 18) 3. Nearby Canal/Breach of Canal Wall (Discussed in Section 18) 4. Nearby sewer/overland flow (discussed in Section 18) 2b. For each identified source, describe how flooding would occur; with reference to any historic records wherever these are available. See Section 18 of Flood Risk Assessment.

2c. What are the existing surface water drainage arrangements for the site? The site is currently set to pasture and has a gentle gradient to the South East boundary. There is a small watercourse which runs along the said boundary. The underlying ground conditions in this are highly permeable sands and gravel, and as such we believe that the surface water generally dissipates into the underlying sands and gravels.

3. Probability

3a. Which flood zone is the site within? Flood Zone 2

3b. If there is a Strategic Flood Risk Assessment covering this site, what does it show? The Strategic Flood Risk Assessment indicates that the site is within Flood Zone 3a. However, this has been superseded by more recent hydraulic modelling data which classifies the site as Flood Zone 2.

3c. What is the probability of the site flooding taking account of the contents of the SFRA and of any further site-specific assessment? 1 in 1000 (0.1%)

3d. What are the existing rates and volumes of run-off generated by the site? Greenfield runoff.

4. Climate change

4a. How is flood risk at the site likely to be affected by climate change? The site could be at risk in 1 in 100 year event when allowance is made for climate change.

5. Detailed development proposals

5a Please provide details of the development layout, referring to the relevant drawings. In Appendix C the Architect’s proposed site layout is provided.

5b. Where appropriate, demonstrate how land uses most sensitive to flood damage have been placed in areas within the site that are at least risk of flooding. N/A

6. Flood risk management measures

6a. How will the site be protected from flooding, including the potential impacts of climate change, over the development's lifetime? The finished floor levels of the proposed dwellings will be set 600mm above the 1 in 100 year fluvial flood level including an allowance for climate change. Section 18 of FRA details approach taken to deriving this level.

7. Off site impacts

7a. How will you ensure that your proposed development and the measures to protect your site from flooding will not increase the flood risk elsewhere? The post development surface water runoff will be restricted to Greenfield runoff rates.

7b. How will you prevent run-off from the completed development causing an impact elsewhere? The discharge will be restricted to the existing Greenfield runoff rate by the use of a combination of the mitigation measures noted and discussed in Paragraph 14.

8. Residual risks

8a. What flood related risks will remain after you have implemented the measures to protect the site from flooding? None identified. With the finished floor levels set at 600mm above the final flood extent there will be no residual risk as the property will be above the 100 yr + CC and 1000 yr defended scenarios.

8b. How, and by whom, will these risks be managed over the lifetime of the development? Not applicable (no risk) 9.0 Introduction

Central & Country Developments Ltd, have instructed Shepherd Gilmour Infrastructure Ltd. to undertake a Flood Risk Assessment (FRA - this report) for the redevelopment of Land at Tatenhill Lane, Branston, Burton upon Trent.

This FRA has been produced in accordance with the National Planning Policy Framework (NPPF), the Technical Guidance to the NPPF and EA Flood Risk Standing Advice v.3.1.

Information referred to during the preparation of this Flood Risk Assessment has been gathered from the Environment Agency, Severn Trent Water and the site owner.

Flood risk to the site from the following sources has been assessed.

a. Fluvial b. Groundwater c. Surface water runoff d. Canal breach

10.0 Site Description

The site location and extent is shown in Appendix A and Figure 1 of this report. The centre of the site is located at OS grid ref Eastings 421725, Northings 321150. The site is currently an undeveloped grass field covering an area of 2.55 Ha. To the North East of the site there are existing residential properties, to the South West lie open water bodies known collectively as Branston Water Park. The Trent and Mersey Canal borders the site to the North West. To the South East the site is bordered by a small area of woodland which abuts the footpath and children’s play area within the Branston Water Park and the container depot and A38 beyond.

A topographical survey covering the site area has been undertaken to Ordnance Datum. This is included as Appendix B and shows that the site has a small gradient from East to West. This survey shows that elevations on the site range from 46.94mAOD in the southern corner of the site to 47.90mAOD along the North West site boundary.

Figure 1. Development site location

Site

11.0 The Proposal

The Application comprises a development of 55 residential units. The proposed site layout is provided in Appendix C.

12.0 Flood Zoning

The Environment Agency Flood Map for the site area (replicated below in Figure 2) shows the site to be located in Flood Zone 2 (showing areas with a medium probability of flooding). In accordance with Tables 1, 2 and 3 in the Technical Guidance to the NPPF, residential units are categorised as 'more vulnerable' which is considered appropriate in Flood Zone 2. Therefore the sequential test is satisfied.

13.0 Managing Site Runoff

13.1 Existing Site Drainage

The existing site is Greenfield with a gentle gradient towards the south east boundary.

13.2 Requirements for Surface Water Drainage

The general requirement for managing surface water is that “development should not increase the flood risk elsewhere”. In practical terms, this means that the runoff from: a. New impermeable areas should be limited to the ‘Greenfield ‘site runoff. b. ‘Brownfield’ sites and existing impermeable areas should be limited to current 1 in 1 year rates.

Both of these rates represent betterment from the existing condition for all storm events with a return period of more than one year and arrangements should be made to contain flood volumes up to the 1 in 100 year + 30% rainfall event on the site. This is applicable for sites with a predicted life span up to 2115 in accordance with Table 5 of the Technical Guidance to NPPF.

The above requirements have been used as the basis for determining allowable discharge rates and requirements for the provision of storage.

13.3 Current Runoff

Greenfield runoff estimated at 2l/s/ha. 13.4 Proposed Runoff Rates

Equivalent Greenfield runoff rate 2l/s/ha.

14.0 Surface Water Runoff Mitigation

In order to achieve the requirement that the development should not worsen flooding elsewhere, appropriate mitigation should be employed to manage additional site runoff.

15.0 Detailed Design

At this stage of the detailed design, it is not proposed to connect the rainwater into the nearby adopted combined sewer, however attached in Appendix F of this report is a letter received from Severn Trent, which gives an in principle approval to such a connection, subject to exhausting all other available options.

A number of porosity tests have been carried out, the results of which are as follows. (Detailed site logs are provided in Appendix H)

BH2 – Test 1 – water drained away very quickly no soil infiltration rate recorded. Test 2 – Soil infiltration rate = 1.1m/s -4 Test 3 – Soil infiltration rate = 1.1m/s -4

BH3 – Test 1 – Soil Infiltration rate = 1.5m/s -3 Test 3 – Soil infiltration rate = 7.3m/s -5

Each individual house will be designed such that all the rainwater will be collected into a rainwater harvesting tank. The tank will be designed with an overflow which will discharge into an infiltration trench/French drain in the rear garden. The first treatment train is the 700mm deep 22m 2 harvesting tank, the second being the soak away system and the third train being the overflow from the infiltration system into the informal swale along the rear of the gardens. For estimating purposes we have ignored the reuse of the water in the property and include in Appendix G the calculations for a 6m x 4m x 0.7m deep cellular storage, which is capable of storing and soaking away the rain water from a 1 in 100 year storm + 30%.

All infiltration systems have been designed as a cascade system, linked together with overflow pipes.

We would also note, as can be seen in the calculation sheets, that a factor of Safety of 2 has been used in each infiltration/attenuation calculation. At detailed design stage we would suggest that this could be reduced to 1.

The private drives will be designed as permeable, with built in storage. In Appendix G we enclose the infiltration calculations which demonstrate that by using a 700mm stone drive the storage within the stone is sufficient to attenuate the flow from the 1 in 100 year + 30% storm.

The private drives will be laid flat and we would suggest that a small fin drain is incorporated as an overflow, which will be connected into the land drain which runs through the rear garden.

Therefore the first train will be the permeable paving, which has sufficient storage for the 1 in 100+30% storm (including a factor of Safety of 2) the second train being the land drain/swale in the rear garden.

The drainage system in the highway will be designed to capture the drainage from the road and discharge it into a stone layer beneath the road. This layer has been designed to infiltrate the water into the ground beneath. This infiltration layer has been designed to attenuate the water from a 1 in 100 year rainfall event with an allowance for climate change. The Micro Drainage analysis for this system is included in Appendix G.

As a final train of mitigation, it is proposed to connect a high level overflow from the individual soakaway system into the existing watercourse which runs along the South East boundary of the site. Similarly a high level overflow will be connected from the road way horizontal soak away. The design of these overflows will be such that they will only become operational for rainfall events of greater than 1 in 100 years.

16.0 Climate Change

The detailed design of the surface water system will include climate change allowances. For site runoff the Technical Guidance to the NPPF states that rainfall intensities for design of runoff volumes should be increased by 30%. At detailed design stage this factor will be applied to the rainfall intensity when calculating the final drainage network for the site.

17.0 Available Information

17.1 Environment Agency Data

In order to prepare this FRA a data request was sent to the Environment Agency. The information returned is included in Appendix D of this report.

17.2 Severn Trent Water Consultation

The nearest Severn Trent Water sewer is located within Tatenhill Road and is a 225mm diameter combined foul sewer. Discussions with Mr Steve Ralph of Severn Trent Water, indicate that this sewer is at capacity however it has no records of flooding. Due to the proposed properties’ remoteness from this sewer the Flood Risk posed by this sewer is judged as being negligible.

18.0 Assessment of Flood Risk

Fluvial

The fluvial flood risk from the River Trent and Tatenhill Brook has been assessed using the results of a 1D-2D linked ISIS-TUFLOW model. The results indicate that the site is not at risk of inundation during a 1 in 100 year event; however flooding could occur in the 1 in 100 year + climate change and 1 in 1000 year events. The Environment Agency has provided modelled flood levels based on the ISIS- TUFLOW model which are summarised in the table below.

Table 1. Modelled flood levels mAOD 1 2 3 4 5 6 7 8 9 UNDEF 1000yr 48.33 48.36 48.35 48.36 48.36 48.36 48.36 48.36 48.36 100yrCC - 47.62 - 47.62 47.62 47.62 47.62 47.62 - 100yr ------DEF 1000yr 48.36 48.38 48.37 48.38 48.38 48.38 48.38 48.38 48.38 100yrCC - 48.22 48.22 48.22 48.22 48.22 48.22 48.22 48.22 100yr ------

It should be noted that flood defences on the River Trent are located downstream of the site. The defences have the effect of increasing water levels upstream, hence the higher water levels predicted on site in the ‘defended’ scenario.

The locations for each of the model outputs above are summarised in Figure 3 and associated flood extents are shown in Appendix D. Figure 3 Spot locations

Ground Water

Shepherd Gilmour’s historic knowledge of this area indicates that the natural ground water level is some 1.5m below existing ground level. Based on the proposed finished floor levels being at or above the existing ground levels, the Risk of groundwater flooding to the development is classed as negligible.

Nearby Sewer Systems

Based on the consultation with Severn Trent Water noted above the risk of flooding to the site from the nearby sewers is classed as negligible.

Trent and Mersey Canal

As discussed earlier in this report, the Trent and Mersey Canal makes up the North Western Boundary of the site. The flow of water in the Trent and Mersey Canal is actively controlled by the Canal and River Trust. Based on the information from the site’s topographical survey, it can be seen that the general water level in the canal is 47.81m AOD. The tow path level next to the canal, and hence the North Western boundary of the site, has a general level of 48.12m AOD with a gentle slope into the site down to a general level of 47.45m AOD. The tow path is in a good condition and some 2 m wide.

The proposed minimum Finished Floor Level (FFL) for the development has been set at a minimum level of 48.82m AOD and as such is higher than the canal water level. Consequently, the risk of flooding posed by the canal is perceived as low.

19.0 Proposed Mitigation

Finished Floor Levels

It has been advised by the EA that finished floor levels are set to a minimum of 600mm above the 1 in 100 event allowing for climate change. The modelled flood levels provided by the EA indicates that the 1 in 100 year + CC flood level at the site is 48.82.

Finished floor levels should therefore be set at a minimum of 48.82m AOD.

Flood Response and Evacuation Plan

The site falls within the Environment Agency’s Flood Warning Area for “River Trent at Burton upon Trent from Branston to Clay Mills behind flood defences”. Occupiers of the site will be able to sign up to the EA's Floodline Warnings Direct Service to receive flood warnings relating to this area. Flood warnings on the River Trent at Burton upon Trent have a significant lead time reflecting the size and shape of the catchment. This means that flood warnings are likely to be particularly effective and well established. The extent of the area is shown in Figure 5.

Figure 5. Environment Agency Flood Warning Area

It is recommended that site occupants should sign up to receive these targeted flood warnings and this can be done by calling the Environment Agency’s Floodline on 0845 988 1188, select option 1 and enter quick-dial number 05211321. Should a flood event be forecast for this area warnings will also be provided via local radio and television stations.

Occupants should be briefed as to the perceived risk to the site and should be provided with information describing how best to respond to flood warnings, including the evacuation plan described below. The actions associated with the level of flood warning are provided in Table 2.

In the event of a severe flood warning and the evacuation is required, it is recommend that the evacuation route presented below is followed.

Evacuation Route

The objective of the evacuation route is to provide the safest route for pedestrians to get to land located in Flood Zone 1. The following evacuation route is proposed should there be a need to evacuate the property during times of flooding from the River Trent.

The safest route to Flood Zone 1 is to exit the site to Tatenhill Lane, turn left and drive/walk across the canal. This area of Tatenhill Lane is in Flood Zone 1. Topographic elevation increases quickly as the road continues north towards Tatenhill, allowing safe vehicular and pedestrian access/egress to the site. 20.0 Conclusions

In summary:

a) It is proposed to develop land off Tatenhill Lane at Burton upon Trent for a 55 unit residential scheme. The site is currently used as grassland.

b) The main River Trent is perceived as presenting the primary threat of flooding to the site. The probability of flooding from this source is rated by the EA Flood Map as medium. Consequently, the site is located within Flood Zone 2.

c) Other sources of flooding to the site are considered to present only a low risk.

d) Peak 1 in 100 year + CC flood levels from the River Trent have been provided by the EA. The predicted flood level is 48.22.

e) Finished floor levels for the proposed development are to be set at a minimum of 600mm above the derived 1 in 100 year + CC flood level of 48.22mAOD.

f) Current runoff rates have been calculated to determine allowable runoff rate.

g) The proposed development will not result in increased runoff due to the mitigation measures specified.

h) The use of Sustainable Drainage System techniques has been reviewed and their use as part of the overall scheme for site runoff control is advocated.

i) A previous proposal at the site has been the subject of a Sequential Test, which was approved by East Staffordshire Borough Council. The Sequential Test has been updated for the current proposals and all information is presented in Appendix E.

21.0 Recommendations

a) A detailed site drainage plan should be prepared and agreed with the local authority before development commences.

b) Runoff from the site post development should be restricted to existing Greenfield runoff rates. c) The finished floor level for the proposed development should be set at a minimum level of 48.82m AOD. d) Site occupants must sign up to the Environment Agency flood warning service, and should be provided with information regarding the risk of flooding to the site (including a flood response and evacuation plan). e) No sleeping accommodation should be provided on the ground floors of the proposed dwellings.

Dear Steven

RE: Request for information under the Freedom of Information Act 2000 (FOIA) / Environmental Information Regulations 2004 (EIR) - Product 4 - Branston

Thank you for your enquiry which was received on 07 March 2013 and payment made on 13 March 2013.

Requests for Information which are recorded are generally governed by the Freedom of Information Act 2000 (FOIA). The information you have requested is environmental and it is therefore exempted from the provisions of FOIA by FOIA s.39 (1). We have therefore considered your request under the provisions of the Environmental Information Regulations 2004 (EIR).

Flood Map

According to our published Flood Map, which provides a general estimate of the likelihood of flooding across England & Wales, the area/site is shown to be within Flood Zone 2 (the area which may have an annual chance of flooding of between 0.1% and 1% (i.e. between 1000 to 1 and 100 to 1) from rivers ignoring the presence and effect of flood defences). The flood zone is associated with the Tatenhill Brook and the River Trent although the site is protected from flooding from the Trent, to a degree, by flood defences. As the site is below flood level the developer should be aware of the risk of flooding due to a failure or overtopping of the defence by a more severe event than designed for. Please find enclosed a Flood Map in the vicinity of the property.

Modelled Levels

The nearest main rivers are the River Trent to the south east, and the Tatenhill Brook. There are modelled levels enclosed for the nearest node points to the site (see the Flood Map).

Defences

The Defences table enclosed lists the flood defences shown on the enclosed plan, with construction dates. The estimated protection given by these flood defences is from a 1 in 200 year flood event.

Environment Agency, 9 Wellington Crescent, Fradley Park, Lichfield, Staffs, WS13 8RR Customer services line: 03708 506 506 Email: [email protected] www,environment-agency.gov.uk You may wish to contact the Local Authority to obtain further information regarding localised flooding from drains, culverts and small watercourses, and regarding existing or planned flood defence measures.

Stage map

The provided flood stage data shown on the Stage Grid map has been derived from a 1D-2D linked ISIS-TUFLOW hydraulic model, for a 1000 year event in an undefended scenario. Levels are extracted from the 2D floodplain data and are therefore applicable at site scale.

Record of Flooding

Examination of our records of Historic Flooding (see explanation below) shows that an area to the north of the site was flooded in 1955. Please note that these records show flooding to the land and do not necessarily indicate that properties within the historic flood extents were flooded internally. It is also possible that the pattern of flooding in this area has changed and that this area would now flood under different circumstances

You may also wish to contact your local authority or internal drainage board, to see if they have other relevant local flood information.

What are our records of Historic Flooding?

Our records of Historic Flooding show the extents of known flooding from rivers, the sea, and groundwater. It cannot show all the flooding that may ever have occurred – we can only show flooding where we have adequate records. So, just because an area of land is shown outside the extents of our recorded flooding does not mean it has never flooded. As more data on historic flooding comes to light, and as flood incidents occur, then we will record this where we have adequate information to do so.

I hope that we have correctly interpreted your request. Please see the Standard Notice for details of permitted use.

If you are not satisfied with our response to your request for information you can contact us to ask for our decision to be reviewed. If you are still not satisfied following this, you can then make an appeal to the Information Commissioner, who is the statutory regulator for Freedom of Information.

APPENDIX E

Land off Tatenhill Lane, Branston

Proposed Residential Scheme of up to 55 dwellings

Sequential Assessment

The application site was previously granted planning permission for up to 28 dwellings on 24 October 2011 (Ref: P/2010/01245/MB/PO). At that time the site was identified with Flood Zone 3a. A sequential assessment supported the application.

A full assessment of sites was undertaken (appended). This considered sites contained within the Draft Strategic Housing Land Availability Assessment (SHLAA) March 2009, including those sites within the Phase 1 Housing Land Availability Assessment of August 2007. Sites within the same or a lower flood zone were appraised. As identified, many sites were constrained and included several operational business premises. Overall, the assessment identified the need for the application site to meet growing housing needs, making reference to the lack of sites within a lower flood risk category to meet those needs.

As explained in the FRA that is submitted with this planning application, following additional research and the detailed modelling of the River Trent it has been found that the application site is now within a lower flood risk category - Flood Zone 2.

Since the grant of planning permission, there continues to be a need for housing. This is evidenced within the Preferred Option Report of the emerging Local Plan which sets out the requirement for 8935 houses to be delivered between 2012 and 2031. The principal focus for this development is to be Burton upon Trent and Uttoxeter. The update to the Strategic Housing Land Availability Assessment 2011 identifies a range of potential sites for housing development within the Burton area, including the application site. It also identifies several large scale development sites beyond the settlement boundary.

Having regard to this evidence base which identifies the need for housing coupled with the lack of sufficient capacity within the urban area, the Preferred Option Report of the Local Plan proposes several large scale developments on the urban fringe. These sites include areas of land within the same flood risk zone as the application site and above and notably beyond the settlement boundary.

In sequential terms the application site is within the settlement boundary of Burton upon Trent, is already a commitment in terms of the existing planning permission and is identified for development within the Strategic Housing Land Availability Assessment. Given the recognised need to identify large sites to meet future development needs beyond the settlement boundary, in sequential terms it is considered that the application site passes the sequential assessment. Further, it is logical to use such a site more efficiently, as is proposed by the planning application.

1 Pro rata windfall allowance can be calculated using the LPA's average historic windfall rate (HWR) in relation to the alternative sites that can reasonably be expected to come forward in zones 1 and 2. To do this, multiply the windfall rate for the whole district (e.g. 200 dwellings pa) by the proportion of the LPA district (or alternative site search area) in Flood Zones 1and 2. For example, if the district is approximately 90% Flood Zone 1 and 2, the reasonably available sites are as follows: 0.9 x 200 = 180. 2 based on LDF density policies and past performance 3 constraints to delivery include: availability, policy restrictions, physical problems or limitations, potential impacts of the development, and future environmental conditions that would be experienced by the inhabitants of the development.

Conclusion: Are there any reasonably available sites in a lower flood risk zone or at a lower risk of flooding than the application site or has the windfall allowance been used up in Flood Zones 1 and 2?

The proposal seeks to provide sustainable and aspirational homes that will contribute to meeting local housing needs within Branston and which, in turn, will contribute to meeting growing housing needs within Burton upon Trent and East Staffordshire. Having regard to the above assessment, there are insufficient reasonably available alternative sites that are suitable and appropriate for the development proposed, which are at a lower risk of flooding and which can meet the housing needs of the area as part of the growth point/ regeneration agenda. . The above assessment identifies that sites within Flood Zone 3a are required if current housing needs are to be met.

Dear Sir,

Re: PPS 25 Sequential Test – Residential development, Land to the rear of Tatenhill Lane, Burton upon Trent

I refer to your PPS 25 flood risk sequential test received by this department on the 19 th March 2010 relating to the above site.

I can confirm that the submitted sequential test, as required under Planning Policy Statement 25: Development and Flood Risk is acceptable, and the Local Planning Authority agrees with the submitted findings.

If you have any further queries please do not hesitate to contact me on the above direct dial number.

Yours faithfully

Mike Brown Area Planning Officer [email protected]

Mahmood Azam, BEng (Hons), MSc, MIED, Director of Development and Regeneration The Exception Test

As the application site is situated within Flood Zone 3a and the development is classed as ‘More Vulnerable,’ according to table D3 of PPS25, an Exception Test is required. This sets out three elements which need to be satisfied as follows:

a) It must be demonstrated that the development provides wider sustainability benefits to the community that outweigh flood risk, informed by the Strategic Flood Risk Assessment where one has been prepared.

b) The development should be on developable, previously developed land, or if it is not, that there are no reasonable alternative sites available.

c) A flood risk assessment must demonstrate that the development will be safe, without increasing flood risk elsewhere, and where possible, will reduce risk overall.

We address these as follows:

Sustainable Development

Growth point status is designed to produce significant private sector investment in residential and employment development with one of the aims being to help deliver a better planned mix of new housing to be implemented in a sustainable form. A key objective of this growth agenda is to promote the regeneration of Burton upon Trent.

The proposed development will support the above objectives by providing attractive high quality aspirational homes that will improve the housing mix.

The application site lies within a sustainable location within the settlement boundary of Burton upon Trent and within walking distance of a range of facilities including employment areas, schools, services and leisure facilities. It will also bring forward a form of development that meets other sustainability credentials through the use of the following design elements:

- Ground source heat pumps; - Photovoltaic panels; - High Insulation levels; - Protection against overheating; - Rainwater harvesting and grey water recycling; - Passive solar gain; - Sustainable drainage.

The application proposals will therefore bring forward much needed residential development to the town and will deliver a scheme with high sustainability credentials to the benefit of the wider community.

Previously developed land

Whilst the application site is not previously developed, it is land within the urban area and which has been identified as a site suitable for residential development within East Staffordshire’s Strategic Housing Land Availability Assessment and with a good sustainability score.

As demonstrated by the Sequential Assessment there are insufficient reasonably available alternative sites that are suitable and appropriate for the development proposed, which are at a lower risk of flooding and which can meet the housing needs of the area as part of the growth point/ regeneration agenda.

Flood risk

As confirmed by the FRA the proposed development will be safe and will not increase flood risk elsewhere.

Having regard to the above, it is considered that the proposed development complies with all three criteria of the Exception Test.
