3 1.0 Introduction RS Mcleod Ltd are developing a site at Dulicht Court, Grantown on Spey with the site centre at National Grid Reference NJ 02592 28018. The entire site extends to an area of approximately 5.66Ha and the site is divided into 2 phases. Phase 1 (23 houses) has been completed and Phase 2 currently consists of 29 units/building plots. For the purposes of this report we have divided Phase 2 into 2 sub phases, 2a (19 units) & 2b (10 building plots). Phase 2a has been partially completed with 16 units completed and a further 3 units to be commenced. On Phase 2b, the developer is submitting a planning application to change the 10 building plots into 3 detached houses and 16 semi-detached houses. The attached Dwg 10223-LP1 shows the location of the site and also the layout of the phases (Refer to Appendix 1). G & D Engineering Services have been appointed by RS Mcleod Ltd to carry out a Surface Water Management Plan in accordance with current standards and specifications of Scottish Water, SEPA and Highland Council in terms of the site surface water drainage. 2.0 Preliminary Investigations and Consultations The engineer has previously carried out investigations into establishing the extents and capacities of the current public drainage network and culverts. 3.0 Existing Site Drainage Drainage records were obtained from Scottish Water (Refer to Appendix 2) which indicate the existing sewers constructed on site are separate foul and surface water sewers but are yet to be adopted. The foul drainage connects to existing foul sewers to the north and south of the site and the surface water run-off discharges into The Kylintra Burn via a Detention Basin and swale. Due to the site topography, building plots 6 – 10 could not connect by gravity into the surface water sewers constructed on site and it was intended to discharge the surface water run off from these plots to individual private soakaways. (Refer to Appendix 3) 4.0 Proposed Foul Drainage A foul sewer system has been constructed in Phases 1 & 2a to discharge the foul flows from Phase 2b. The foul flows plots 43 – 52 are to discharge into the existing foul sewers by means of new or existing house connections and a new section of foul sewer is required to discharge the foul flows from plots 53 – 61 to FW29. A foul drainage layout is shown on Dwg 12023-PD2 (Refer to Appendix 4). A Pre- Development Enquiry has been submitted to Scottish Water and we await their confirmation of capacity for the additional foul flows from additional 9 dwellings.
4 5.0 Proposed Surface Water Drainage 5.1 Surface Water Design Criteria Scottish Water and Highland Council have different surface water design criteria. Scottish Water surface sewer design criteria is for the 1 in 30 year + 40% CC with consideration of flow path routing for the 1 in 200 year storm event. Highland Council current surface water sewer design criteria is for the 1 in 200 year + 40% CC with consideration for flow paths routing for the 1 in 200 year storm event with no detriment flooding to proposed or existing properties. For the purposes of this report, we have adopted the Highland Council design criteria as it is the more onerous criteria. A surface water drainage layout is shown on Dwg 10223-PD2 (Refer to Appendix 4) and all drained hardstanding areas are shown on Dwg 10223-HS1 (Refer to Appendix 5) . Plots 43 – 52 are situated on the original site of building plots 1 – 5. The surface water sewer previously constructed was designed to drain the surface water flows from these building plots (Refer to Appendix 9). Plots 43 – 52 will connect to the existing surface water sewer by means of new and existing sewer connections. The drained hardstanding area from a large building plot and 2 semi-detached houses are very similar and therefore the existing surface water sewers and Detention Basin are deemed to be of adequate size to discharge the surface water flows from these plots. Plots 53 – 61 are situated on the original site of building plots 6 – 10. As mentioned previously in section 3.0, these plots were to be drained to individual soakaways. However due to the reduced plot sizes it would not be possible to construct soakaways for each house whilst complying with The Building Regulations. We therefore propose to construct a new surface water sewer system for these plots that will discharge to the Kylintra Burn through a new Detention Basin. The surface water layout for Phase 2b is shown on Dwg 10223-PD2 (Refer to Appendix 4). 5.2 Surface Water Run-off Rate The greenfield run off rate for the plots (53−61) is assessed at 3.80L/s and greenfield calculations are provided in Appendix 5. The surface water flows will be restricted by means of a hydrobrake built at manhole S1. 5.3 Surface Water Design & Attenuation The attached Surface Water Model (Refer to Appendix 6) confirms that the surface water sewer system (plots 54 – 61) does not surcharge during the 1 in 30 + 40% CC storm event and we have upsized 2 sections of sewer to ensure the system does not surcharge during the 1 in 200 year + 40% CC storm event. The model confirms that the total volume of attenuation required to attenuate the 1 in 30 year + 40% CC to the restricted flow rates is 121 m³ of attenuation required to attenuate the 1 in 200 year + 40% CC to the restricted flow rates is 187 m³. The Detention Basin provides a storage volume of 398 m³.
5. 5.2 Surface Water Flowpaths It is a statutory requirement that site levels are designed to ensure safe surface water flow paths are provided throughout the developed site in the event of extreme rainfall events or a blockage of the system. The Pre-Development surface water flow paths are shown on Dwg 10223-FP1 (Refer to Appendix 7) and the Post-Development surface water flow paths are shown on Dwg 10223-FP2 (Refer to Appendix 8). The latter drawing shows that safe flow paths are provided throughout the development in the event of a total blockage in the Surface Water Drainage System. 6.0 SUDS It is now planning policy that the surface water discharge from all new development must include SUDS. SEPA have established the minimum treatment requirements for all hard standing areas in their document ” Simple Index Approach Calculation”. We confirm that all drained hardstanding areas as shown on Dwg 10223-HS1 (Refer to Appendix 5) have a level of treatment to comply with this document and we would confirm our treatment measures as follows 6.1 SUDS Measures Roads (< 300 traffic movements a day) Treatment Level Required — 0.50÷0.40÷0.40 Detention Basin Treatment Level — 0.50÷0.50÷0.60 (Pass) Detention Basin Maintenance Responsibility — Scottish Water Maintenance — Seasonal cutting of grass and cleaning of inlets & outlets Private Driveways Treatment Level Required — 0.50÷0.40÷0.40 Detention Basin Treatment Level — 0.50÷0.50÷0.60 (Pass) Detention Basin Maintenance Responsibility – Scottish Water Maintenance — Seasonal cutting of grass and cleaning of inlets & outlets Roof Areas Treatment Level Required — 0.20÷0.20÷0.05 Detention Basin Treatment Level — 0.50÷0.50÷0.60 (Pass) Detention Basin Maintenance Responsibility – Scottish Water Maintenance — Seasonal cutting of grass and cleaning of inlets & outlets Hydrobrake Maintenance Responsibility — Scottish Water Maintenance — Per manufacturers maintenance régime
