17. Advisory Notes: As of 7th January 2019, this proposed development may be subject to Schedule 3 of the Flood and Water Management Act 2010. The development may therefore require approval of Sustainable Drainage Systems (SuDS) features, from the determining SuDS Approval Body (SAB), in accordance with the 'Statutory standards for sustainable drainage systems – designing, constructing, operating and maintaining surface water drainage systems'. The planning permission hereby granted does not extend any rights to carry out any works to the public sewerage or water supply systems without first having obtained the necessary permissions required by the Water industries Act 1991. Any alterations to existing premises resulting in the creation of additional premises or merging of existing premises must also be constructed so that each is separately connected to the Company’s water main and can be separately metered. Please contact our new connections team on 0800 917 2652 for further information on water and sewerage connections. The applicant is also advised that some public sewers and lateral drains may not be recorded on our maps of public sewers because they were originally privately owned and were transferred into public ownership by nature of the Water Industry (Schemes for Adoption of Private Sewers) Regulations 2011. The presence of such assets may affect the proposal. In order to assist us in dealing with the proposal the applicant may contact Dwr Cymru Welsh Water to establish the location and status of the apparatus. Under the Water Industry Act 1991 Dwr Cymru Welsh Water has rights of access to its apparatus at all times. In accordance with Planning Policy Wales (Edition 12) and Technical Advice Note 12 (Design), the applicant is advised to take a sustainable approach in considering water supply in new development proposals, including utilising approaches that improve water efficiency and reduce water consumption. We would recommend that the applicant liaises with the relevant Local Authority Building Control department to discuss their water efficiency requirements. Dwr Cymru Welsh Water is not responsible for fire protection or for providing suitable fire flows. Providing fire flows and fire protection are the responsibility of the appropriate regional Fire Services. We refer you to the 3rd Edition of the National Guidance Document on the Provision of Water for Fire Fighting published by the Local Government Association and Water UK.
18. I ddarparu gwelliannau bioamrywiaeth yn unol â Pholisi Strategol D o Gynllun Datblygu Lleol Eryri a Pholisi Cynllunio Cymru a fabwysiadwyd.
19. Er mwyn atal gorlwytho hydrolig y system garthffosiaeth gyhoeddus, er mwyn amddiffyn iechyd a diogelwch trigolion presennol a sicrhau nad oes unrhyw lygredd na niwed i'r amgylchedd.
20. Er mwyn sicrhau safon foddhaol o ran ymddangosiad y datblygiad a defnyddio deunyddiau adeiladu lleol priodol, yn unol â Pholisïau Cynllun Datblygu Lleol Eryri ac yn benodol polisïau 1, 6 ac A.
21. Er mwyn sicrhau safon foddhaol o ran ymddangosiad y datblygiad a defnyddio deunyddiau adeiladu lleol priodol, yn unol â Pholisïau Cynllun Datblygu Lleol Eryri ac yn benodol polisïau 1, 6 ac A.
22. Nodiadau Cynghori: Deddf Rheoli D"{r 2010. Felly, efallai y bydd angen cymeradwyaeth ar gyfer nodweddion Systemau Draenio Cynaliadwy (SuDS) ar gyfer y datblygiad, gan y Corff Cymeradwyo SuDS (SAB) sy'n penderfynu, yn unol â'r 'Safonau statudol ar gyfer systemau draenio cynaliadwy – dylunio, adeiladu, gweithredu a chynnal systemau draenio d"{r wyneb'. Nid yw'r caniatâd cynllunio a roddir drwy hyn yn ymestyn unrhyw hawliau i wneud unrhyw waith i'r systemau carthffosiaeth gyhoeddus neu gyflenwi d"{r heb gael y caniatâd angenrheidiol sy'n ofynnol gan Ddeddf Diwydiannau D"{r 1991 yn gyntaf. Rhaid i unrhyw newidiadau i safleoedd presennol sy'n arwain at greu safleoedd ychwanegol neu uno safleoedd presennol hefyd gael eu hadeiladu fel bod pob un wedi'i gysylltu ar wahân â phrif bibell dd"{r y Cwmni a gellir ei fesur ar wahân. Cysylltwch â'n tîm cysylltiadau newydd ar 0800 917 2652 am ragor o wybodaeth am gysylltiadau d"{r a charthffosiaeth. Cynghorir yr ymgeisydd hefyd nad yw rhai carthffosydd cyhoeddus a draeniau ochrol o bosibl wedi'u cofnodi ar ein mapiau o garthffosydd cyhoeddus oherwydd eu bod yn wreiddiol yn eiddo preifat ac wedi'u trosglwyddo i berchnogaeth gyhoeddus oherwydd natur Rheoliadau'r Diwydiant D"{r (Cynlluniau ar gyfer Mabwysiadu Carthffosydd Preifat) 2011. Gall presenoldeb asedau o'r fath effeithio ar y cynnig. Er mwyn ein cynorthwyo i ddelio â'r cynnig, gall yr ymgeisydd gysylltu â D"{r Cymru i sefydlu lleoliad a statws y cyfarpar. O dan Ddeddf y Diwydiant D"{r 1991 mae gan D"{r Cymru hawliau mynediad i'w gyfarpar bob amser. Yn unol â Pholisi Cynllunio Cymru (Argraffiad 12) a Nodyn Cyngor Technegol 12 (Dylunio), cynghorir yr ymgeisydd i fabwysiadu dull cynaliadwy wrth ystyried cyflenwad d"{r mewn cynigion datblygu newydd, gan gynnwys defnyddio dulliau sy'n gwella effeithlonrwydd d"{r ac yn lleihau'r defnydd o dd"{r. Byddem yn argymell bod yr ymgeisydd yn cysylltu ag adran Rheoli Adeiladu'r Awdurdod Lleol perthnasol i drafod eu gofynion effeithlonrwydd d"{r. Nid yw D"{r Cymru yn gyfrifol am ddiogelu rhag tân nac am ddarparu llifau tân addas. Cyfrifoldeb y Gwasanaethau Tân rhanbarthol priodol yw darparu llifau tân ac amddiffyn rhag tân. Rydym yn eich cyfeirio at 3ydd Argraffiad y Ddogfen Ganllawiau Genedlaethol ar Ddarparu D"{r ar gyfer Diffodd Tân a gyhoeddwyd gan Gymdeithas Llywodraeth Leol a Water UK.
23. Cyn y defnydd cyntaf o'r datblygiad a gymeradwyir drwy hyn, rhaid gosod y gwelliant bioamrywiaeth canlynol yn y safleoedd a ddangosir ar y cynlluniau a gymeradwyir drwy hyn: - 3 thiwb ystlumod safonol. - 2 flwch gwiail duon pren wedi'u hadeiladu i mewn i ffabrig yr estyniad. Wedi hynny, rhaid cynnal y gwelliant bioamrywiaeth yn unol â chyfarwyddiadau'r gwneuthurwr a rhaid ei gadw am oes y datblygiad; rhaid i unrhyw rai newydd fod o fanyleb gyfwerth.
24. i chaniateir i unrhyw dd"{r wyneb o unrhyw gynnydd yn arwynebedd to'r adeilad / neu arwynebau anhydraidd o fewn ei gwrtil ddraenio'n uniongyrchol nac yn anuniongyrchol i'r system garthffosiaeth gyhoeddus.
25. Rhaid gorchuddio to'r estyniad â llechi mwynau naturiol o Gymru neu lechi o'r un lliw, gwead a nodweddion tywyddio â'r llechi ar brif do'r t"} annedd a'i gynnal wedi hynny.
26. Rhaid i'r deunyddiau allanol yn y datblygiad a gymeradwyir drwy hyn gyd-fynd â lliw, ffurf a gwead y rhai sydd ar y t"} annedd sy'n cael ei ymestyn.
