- Advisory Notes Dwr Cymru The planning permission hereby granted does not extend any rights to carry out any works to the public water supply system 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 connections. 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'. 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.
- Dylid gweithredu'r mesurau gwella bioamrywiaeth fel y'u nodir yn y 'Datganiad Seilwaith Gwyrdd' (5 Chwefror 2026) a gyflwynwyd a'i gymeradwyo drwy hyn ac fel y dangosir ar y cynllun 'Proposed Elevations (Drawing number TR/1025/BR/06) (29/01/2026)' o fewn tri mis ar ôl cwblhau'r datblygiad a'u cadw wedi hynny.
- 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.
- Cyn dechrau unrhyw waith cerrig ar y safle, rhaid adeiladu panel gwaith cerrig prawf gan gynnwys pwyntio o leiaf 2.00 m². Ni ddylid cynnal unrhyw weithrediadau adeiladu mewn carreg ar y safle oni bai a hyd nes y bydd y panel prawf wedi'i archwilio a'i gymeradwyo trwy gais ffurfiol i'r Awdurdod Cynllunio Lleol. Rhaid adeiladu gwaith cerrig yr estyniad yn unol â'r sampl a gymeradwywyd.
- Er mwyn sicrhau gwelliant mewn bioamrywiaeth yn unol â Pholisi Strategol D o Gynllun Datblygu Lleol Eryri a fabwysiadwyd a pharagraff 6.4.5 o Bolisi Cynllunio Cymru.
- Er mwyn sicrhau gwelliant mewn bioamrywiaeth yn unol â Chynlluniau Datblygu Lleol Eryri a 6.4.5 o brosiectau Cynllunio Cymru.
- 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 A, 1, 6 (a 7 os yw'n berthnasol).
- Nodiadau Cynghori: Dwr Cymru Nid yw'r caniatâd cynllunio a roddir drwy hyn yn ymestyn unrhyw hawliau i wneud unrhyw waith i'r system gyflenwi d"{r gyhoeddus heb yn gyntaf gael y caniatâd angenrheidiol sy'n ofynnol gan Ddeddf Diwydiannau D"{r 1991. Rhaid i unrhyw newidiadau i safleoedd presennol sy'n arwain at greu safleoedd ychwanegol neu uno safleoedd presennol gael eu hadeiladu hefyd 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 i gael rhagor o wybodaeth am gysylltiadau d"{r. O 7 Ionawr 2019 ymlaen, gall y datblygiad arfaethedig hwn fod yn ddarostyngedig i Atodlen 3 o Ddeddf Rheoli Llifogydd a D"{r 2010. Felly, efallai y bydd angen cymeradwyaeth ar gyfer nodweddion Systemau Draenio Cynaliadwy (SDCau) ar gyfer y datblygiad, gan y Corff Cymeradwyo SDCau (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'. 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 berthnasol yr Awdurdod Lleol i drafod eu gofynion effeithlonrwydd d"{r. Nid yw D"{r Cymru Welsh Water 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.
