MILTON CRESCENT, HORBURY RD, LUPSET 16/12/15 FLOOD RISK & RUNOFF IMPACT - PRELIMINARY INFORMATION NOTE This note supersedes the previous 19/07/13 response provided to Property Management. Background

1. This grassland site is approx. 8ha (20 acres), part of a larger grassland land holding.

2. The site generally slopes from north west to south east, towards the M1 and Springmill Beck, Ossett.

Flood Risk and Runoff Impact Mitigation

3. All development must mitigate its additional flood risk impact to national standards and reduce overall flood risk where possible, so existing flood risk is not increased.

4. The site is elevated and is likely to be in flood risk zone 1, suitable for residential development.

5. The watercourse shown flowing through the site needs further investigation. The watercourse channel including any inlet pipework at the upstream site boundary or outfall at the downstream site boundary needs to be sized to accommodate the minimum 1 in 100 year plus 20% climate change event.

6. Any works to the watercourse through the site will be subject to prior formal approval

of the Land Drainage Authority under the Land Drainage Act 1991.

7. The drainage strategy and proposals must comply with the national drainage hierarchy in Building Regs Part H.

8. Site investigation is required to establish the feasibility of surface water infiltration,

and where feasible, accompanied by percolation test results and a geological report to clarify the route of infiltrated flows and potential flood impact on 3

rd party assets.

9. YW’s records show the adjacent residential developments are served by YW adopted

sewers. There do not appear to show any sewers crossing or serving the site.

10. Surface water runoff from the development proposal is required to be mitigated to a maximum total of 20 litres per second with flood storage provided to accommodate the minimum 1 in 100 year + 30% climate change critical event.

11. The surface water drainage strategy for the site needs to employ sustainable urban

drainage techniques(SuDS) where feasible in accordance with Leeds City Region’s SuDS Guidance for Developers.

12. Wakefield Council and Yorkshire Water have well established and proactive drainage

adoption policies and design standards for open storage and associated drainage assets related to residential development sites. Open storage and watercourses should be sited within areas of public open space wherever possible. Adoption would be via a dedicated legal agreement and commuted sum.

13. A runoff impact (water balance) assessment is required to show the volume of runoff

discharged from the proposed site in the 6 hour 1 in 100 year plus 30% climate change event is less than from the existing greenfield site in the 6 hour 1 in 100 year (no climate change) event.

14. Provided the above runoff mitigation measures above are implemented, no off-site mitigation works or commuted sum to works in the wider catchment will be required. End

Dear Ms Mee, Milton Crescent Lupset Wakefield - Pre Planning Enquiry On R099628 Thank you for your recent enquiry. Our charge of £150.00 (plus VAT) will be added to your account with us, reference EPL039. You will receive an invoice for your account in due course. Please find enclosed a complimentary extract from the Statutory Sewer Map which indicates the recorded position of the public sewers. Please note that as of October 2011 and the private to public sewer transfer, there are many uncharted Yorkshire Water assets currently not shown on our records. The following comments reflect our view, with regard to the public sewer network only, based on a 'desk top' study of the site and are valid for a maximum period of twelve months. Existing Infrastructure (Please note:- due to the change in legislation on 01/10/2011 there may be public sewers within the site boundary which is not recorded on the Statutory Sewer Map the presence of which should be taken into account in the design of the scheme) Foul Water Development of the site should take place with separate systems for foul and surface water drainage. The separate systems should extend to the points of discharge to be agreed. Foul water domestic waste should discharge to the 225 mm diameter public combined sewer recorded in Milton Road, at a point to the east of site. From the information supplied, it is not possible to determine if the whole site will drain by gravity to the public sewer network. If the site, or part of it, will not drain by gravity, then it is likely that a sewage pumping station will be required to facilitate connection to the public sewer network. If sewage pumping is required foul water discharge must not exceed 5 (five) litres per second. Surface Water The developer's attention is drawn to Requirement H3 of the Building Regulations 2000. This establishes a preferred hierarchy for surface water disposal. Consideration should firstly be given to discharge to soakaway, infiltration system and watercourse in that priority order.

Sustainable Drainage Systems (SuDS), for example the use of soakaways and/or permeable hardstanding etc, may be a suitable solution for surface water disposal appropriate in this situation. You are advised to seek comments on the suitability of SuDS in this instance from the appropriate authorities. As the proposal site is currently undeveloped no surface water is known to have previously discharged to the public sewer network As such, the local public sewer network does not have capacity to accept any surface water from the proposed site. If SuDS are not viable, the developer is advised to contact the Environment Agency/local Land Drainage Authority with a view to establishing a suitable watercourse for discharge. It is understood that a watercourse is located through/to the of the site. This appears to be the obvious place for surface water disposal (if SuDS are not viable). Please note further restrictions on surface water disposal from the site may be imposed by other parties. You are strongly advised to seek advice/comments from the Environment Agency/Land Drainage Authority, with regard to surface water disposal from the site. Other Observations Any new connection to an existing public sewer will require the prior approval of Yorkshire Water. You may obtain an application form from our website (www.yorkshirewater.com) or by telephoning 0345 120 84 82. An off-site foul and surface water sewer may be required which may be provided by the developer and considered for adoption under Section 104 of the Water Industry Act 1991. Please telephone 0345 120 84 82 for advice on sewer adoptions. Alternatively, the developer may in certain circumstances be able to requisition off-site sewers under Section 98 of the Water Industry Act 1991 for which an application must be made in writing. For further information, please telephone 0345 120 84 82. Prospectively adoptable sewers and pumping stations must be designed and constructed in accordance with the WRc publication "Sewers for Adoption - a design and construction guide for developers" 6th Edition as supplemented by Yorkshire Water's requirements, pursuant to an agreement under Section 104 of the Water Industry Act 1991. An application to enter into a Section 104 agreement must be made in writing prior to any works commencing on site. Please contact our Developer Services Team (telephone 0345 120 84 82) for further information. The public sewer network is for domestic sewage purposes. This generally means foul water for domestic purposes and, where a suitable surface water or combined sewer is available, surface water from the roofs of buildings together with surface water from paved areas of land appurtenant to those buildings. Land and highway drainage have no right of connection to the public sewer network. No land drainage to be connected/discharged to public sewer. As a last resort, highway drainage may be accepted under certain circumstances. If it can be demonstrated, through satisfactory evidence, that SUDS are not a viable option, there are no watercourses or highway drains available and if capacity is available within the public sewer network, highway drainage discharges to the public sewer network may be permitted. In this event, the developer may be required to enter into a formal agreement with Yorkshire Water Services under Section 115 Water Industry Act 1991 to discharge non-domestic flows into the public sewer network. All the above comments are based upon the information and records available at the present time. The information contained in this letter together with that shown on any extract from the Statutory Sewer Map that may be enclosed is believed to be correct and is supplied in good faith.

Please note that capacity in the public sewer network is not reserved for specific future development. It is used up on a 'first come, first served' basis. You should visit the site and establish the line and level of any public sewers affecting your proposals before the commencement of any design work.- Yours sincerely
