1. Introduction

1.1 Terms of Reference

Tulip Engineering Consultancy was commissioned by CB3 Consult Ltd to prepare this Flood Consequences Assessment (FCA) to support a planning application for the development of Industrial Units on brownfield land at Swansea Valley Business Park, Glan Yr Afon, Ystalyfera. Industrial development is classified as “less vulnerable” development in Technical Advice Note (TAN) 15 Development & Flood Risk (Welsh Assembly Government, 2004).

The proposed development site lies within Zone C2 of the Development Advice Map (DAM) published by Natural Resources Wales (NRW). Zone C2 is defined as areas at risk of flooding “without significant flood defence infrastructure” (Welsh Assembly Government, 2004).

The objective of this report is to undertake a study into the hydrological issues affecting the site, and establish whether and to what extent the consequences of flooding can be managed over the lifetime of the development, using the principles and tests set out in TAN 15.

2. Site Description

2.1 Location

Swansea Valley Business Park is an established industrial site which lies between Ystalyfera to the north and Godrergraig to the south. The site is directly bounded to the east by the A4067 Glanyrafon Road, with the banks of the River Tawe situated parallel to the road and approximately 70m away in the south-easterly direction.

The National Grid Reference for the site is: SN 76505 08226.

A site location plan is shown in Figure 1.

2.2 Watercourses

The Afon Tawe is a designated main river which rises in the Brecon Beacons above Llyn y Fan at 590m above sea level and flows in a generally south-westerly direction to Swansea Bay. The river drains a total catchment of some 270km2. The Tawe flows approximately 70m to the east of the proposed development.

The Afon Twrch, also a designated main river and a main tributary of the Tawe, rises in the Black Mountains and flows in a generally southerly direction to Ystalyfera where it joins the Tawe approximately 0.7km north-east of the development site. The Afon Twrch catchment is approximately 50km2 at the confluence with the Tawe.

2.3 Topography

The development site sits in the relatively flat Tawe valley floor some 70m from the river. The width of the valley floor is some 0.8km at this point. The valley floor area widens markedly upstream (north) of the site, where the Twrch joins the Tawe and the two valleys merge.

A plan showing the site location, lidar ground levels, and all OS-mapped watercourses (main rivers and ordinary watercourses) in the vicinity is included in Appendix A.

https://d.docs.live.net/9692ee99776ac28f/Documents/Tulip Engineering Consultancy/Jobs/J009 - Swansea Valley Ind Est FCA/Production/Data - Internal/FCA - Swansea Valley Ind Est.docx

A topographical survey of the development area and adjacent industrial unit dated March 2016 is also included in Appendix A. This shows that the level of the rectangular development plateau is raised some 1m above the adjacent industrial land to the west.

The development site elevation ranges between approximately 58.0m AOD at the northern end to 59.0m AOD at the southern end. The large existing industrial unit and the industrial estate access road immediately to the west are at a lower level of approximately 56.8m AOD. The main road (A4067) to the east is at a similar level to the development site.

2.4 Soils, Geology & Hydrogeology

Site soils are described as loamy in texture and freely draining according to the Cranfield University Soilscapes Viewer.

The geology at the site is described as superficial alluvial deposits (clay, silt, sand and gravel) overlying mudstone, siltstone and sandstone bedrock, according to the BGS Geology of Britain Viewer.

The aquifer designation of the sedimentary bedrock is Secondary A (capable of supporting water supplies at a local rather than strategic scale). The site is not in a groundwater Source Protection Zone area.

2.5 History

The area in the vicinity of the site was historically the location of the Ystalafera Iron & Tin Plate Works. An overlay showing the site location in relation to the 1910 OS Map is shown in Figure 3.

3. Proposed Development

3.1 Layout

The proposed development consists of two industrial sheds housing seven business starter units, with associated access road and parking spaces.

The existing industrial estate access road is to be realigned to run some 7m closer to the existing adjacent industrial building, to increase the developable area of the plot.

Proposed architectural plans and elevations are included in Appendix B.

3.2 Levels

Proposed carpark and building floor levels are not yet finalised, although it is anticipated that proposed ground levels will be similar to existing levels, with small localised differences due to cut/fill redistribution to flatten out the bank at the northern site boundary.

The realigned access road profile will need to be set to ensure suitable access to both the proposed site and tie in to the adjacent large existing industrial unit.

4. Planning Policy and Flood Risk

4.1 Proposed Development and TAN 15

The development proposal is for industrial units on brownfield land in an industrial area of Ystalafera. Industrial development is classified as ‘less vulnerable’ development in TAN 15.

The Development Advice Map (DAM) is a flood map published by NRW for land use planning purposes. It is used alongside Planning Policy Wales and Technical Advice Note (TAN) 15 to direct new development in respect to flood risk. Together, they form a precautionary framework to guide planning applications.

The map is based on Natural Resource Wales' extreme flood outlines (zone C) and the British Geological Survey drift data (zone B). Zone B data was originally published 2004 and updated in 2017. Zone C data is revised quarterly by ongoing hydraulic modelling and represents areas affected by flooding in events with up to a 1 in 1000 annual chance of occurring (0.1% Annual Event Probability), but no allowance for future climate change.

The Development Advice Map in the vicinity of the proposed development is included in Appendix C. The Map shows that the development site currently lies within the blue shaded zone C2 area, defined as “areas of the floodplain without significant flood defence infrastructure”.

TAN15 provides for less vulnerable development in zone C2, subject to application of the justification test, including acceptability of consequences.

4.2 Justification Test

TAN15 Section 6 states that development will be justified if it can be demonstrated that:

1. Its location in zone C is necessary to assist or be part of a local authority regeneration initiative or a local authority strategy required to sustain an existing settlement; or

2. Its location in zone C is necessary to contribute to key employment objectives supported by the local authority, and other key partners, to sustain an existing settlement or region; and

3. It concurs with the aims of Planning Policy Wales and meets the definition of previously developed land; and

4. The potential consequences of a flooding event for the particular type of development have been considered and found to be acceptable.

In this case this development is considered to meet the second and third criteria, whilst the fourth is supported by updated flood modelling undertaken specifically for this FCA, as described in Section 6 and Appendix D of this report.

5. Existing Flood Risk Review

5.1 Historical Flooding

The site has not experienced any flooding in the past according to NRW’s map of historical flood outlines.

5.2 Fluvial Flood Risk

The NRW Zone 2 & 3 Map in Appendix C shows the lower part of the site in zone 3 (up to 1 in 100 annual chance of flooding) and the remaining higher part of the site in zone 2 (up to 1 in 1000 annual chance of flooding).

This map also indicates that the zone 3 area is classed as ‘area benefitting from flood defences’, although this area is not shown as green-coloured zone C1 (defended) on the DAM Map.

A additional ‘Flood Zone Plan’ is included in Appendix C, showing flood zones 2 & 3 overlaid on an map which also includes the site topographical survey, lidar ground elevation data and OS watercourses.

It is important to note that this is the fluvial flood risk as shown on the current (existing) flood maps which guide the planning process. The updated fluvial flood modelling described in Section 6 effectively supersedes this existing fluvial flood risk.

5.3 Surface Water Flood Risk

The surface water flood risk map included in Appendix C shows a high risk area along the existing access road to the industrial estate, with the remainder of the development plot in very low or low risk area.

The existing access road will be reprofiled and drained as part of this development proposal. Furthermore the development site itself will be subject to sustainable drainage design/SAB approval and as such it is considered unlikely that the proposed development will increase the risk of surface water flooding or the rate and volume of surface water runoff.

5.4 Reservoir Flood Risk

The development site is not at risk of flooding from reservoir failure according to NRW’s flood risk mapping.

5.5 Groundwater Flood Risk

The development site is not in an area prone to groundwater flooding according to available BGS mapping, which is supported by NPT’s Local Flood Risk Management Strategy which states that there are no specific areas of groundwater flooding recorded historically in the NPT area.

6. Hydraulic Modelling

6.1 Existing Hydraulic Model

This section of the report will reassess the flood risk indicated by the DAM maps and establish whether the consequences of the risk of flooding may be considered acceptable.

The current DAM Map flood outline in the site locality is informed by the results of flood modelling undertaken in 2016 by JBA Consulting for the Ysgol Gyfun Ystalafera Flood Consequences Assessment. This model was in turn based largely on a 2013 Cwm Twrch 1D-2D model also developed by JBA Consulting on behalf of NRW.

The hydrology calculations from 2016 have now become outdated due to ongoing developments in hydrology methods, guidance and data availability. As part of this development FCA, updated hydrology and modelling has been commissioned.

6.2 Updated Hydraulic Modelling

The updated modelling undertaken by JBA Consulting for this FCA encompassed updated hydrology (input flow) calculations, more realistic application of input flows and 1D model updates. Model scenarios were run using the latest TUFLOW software and current climate change (30%) allowance.

A Technical Note from JBA Consulting summarising the updated modelling exercise, is included in Appendix D of this report.

Results from the updated modelling show that the proposed development floods in neither the 1 in 100 (1%) AEP with climate change allowance, nor the 1 in 1000 (0.1%) AEP. The 0.1% AEP flood map extent is shown in Figure 4.

Flooding is shown to emanate from the right bank of the Afon Twrch some 1km upstream of the site at Ysgol Gyfun Ystalafera. The overland flood flow-path is then southerly before ponding around Varteg Road, but does not reach beyond the roundabout towards the development site.

TAN15 guidelines require a flood-free development level for fluvial flood risk of 1% (1 in 100 annual chance) probability over the lifetime of the development. The updated modelling results displayed in Figure 4 show that the proposed development would be compliant with the flood-free development level criteria (A1.14) of TAN15. Consequently it is clear that no ground level alterations would be required in order to meet this criteria.

Emergency access/egress to/from the site needs to be considered in light of the TAN15 recommendations. The map in Figure 4 indicates that the immediate site access road and mini-roundabout would be flood free during the 0.1% AEP event. The main A4067 Glan Yr Afon road roundabout is shown to suffer flooding up to a depth of 0.6m on the eastern side, which is within the “maximum permissible floodwater depth over the defined route during extreme flooding” figure of 1.0m given in A1.15 of TAN15.

https://d.docs.live.net/9692ee99776ac28f/Documents/Tulip Engineering Consultancy/Jobs/J009 - Swansea Valley Ind Est FCA/Production/Data - Internal/FCA - Swansea Valley Ind Est.docx

Whilst access to the A4067 during the 0.1% APE event may be hampered, the availability of the B4599 would be unaffected and would allow for safe evacuation from the site or access for emergency vehicles if required.

The ‘no flooding elsewhere’ criterion of TAN15 is considered negligible in this assessment since it has been demonstrated that the site would not flood during either the 1%CC or 0.1% AEP events.

7. Conclusions & Recommendations

• This planning application is for industrial development (classed as less vulnerable in TAN15) on brownfield land at Swansea Valley Business Park.

• The requirement for this FCA is due to the proposed development site location in the flood plain (zone C2 of the current Welsh Government Development Advice Map).

• However, updated flood modelling undertaken specifically for this FCA for this development, has demonstrated that the proposed development site is outside the flood plain, that is, flood-free during both the 1%CC and 0.1% AEP events.

• The most up to date analysis of flood risk to the site is therefore shown to be less than that suggested by the current DAM Map, and the key TAN15 acceptability tests in relation to flood-free floor level, no flooding elsewhere and access/egress are all met by default.

• The proposed development is compliant with all key aspects of TAN15 and as such it is considered that this land is suitable for industrial development in relation to planning policy and flood risk.
