- Mae'n rhaid cyflawni'r datblygiad a ganiateir yma yn unol â'r cynlluniau a gymeradwywyd isod: Location Plan – received the 22nd of July 2025 Site Plan – Proposed (Drawing Number: 08/JE 25) – amended March 2026 Elevations – Existing (Drawing number: 03 / JE 25) – dated June 2025 Elevations - Proposed (Drawing number: 06/JE 25) – amended March 2026 Garage - Proposed (Drawing Number: 0.7 / JE 25) – dated June 2025 Ground Floor & Section – Existing (Drawing Number: 01 /JE 25) – dated June 2025 First Floor & Site Section – Existing (Drawing Number: 02/ JE 25) – dated June 2025 Ground and First Floor – Proposed (Drawing Number: 04/JE25) – amended March 2026 Sections – Proposed (Drawing Number: 05/JE25) – amended March 2026 Bat Survey Report – dated October 2025 Green Infrastructure Statement (GIS) – received the 3rd November 2025
- Within three months of the substantial completion of the development the biodiversity enhancement measures identified in the Green Infrastructure Statement (Dated September 2025) hereby approved, shall be installed on the north facing elevation. They shall be implemented as shown on the Existing and Proposed Elevations (Received in November 2025), and all provisions shall be of a woodcrete/woodstone construction and fitted as per the manufacturer’s instruction.
- No surface water from any increase in the roof area of the building /or impermeable surfaces within its curtilage shall be allowed to drain directly or indirectly to the public sewerage system.
- O fewn tri mis i gwblhau'r datblygiad yn sylweddol, rhaid gosod y mesurau gwella bioamrywiaeth a nodwyd yn y Datganiad Seilwaith Gwyrdd (Dyddiedig Medi 2025) a gymeradwywyd drwy hyn, ar y drychiad sy'n wynebu'r gogledd. Rhaid eu gweithredu fel y dangosir ar y Drychiadau Presennol ac Arfaethedig (Derbyniwyd ym mis Tachwedd 2025), a rhaid i'r holl ddarpariaethau fod o adeiladwaith concrit pren/carreg bren a'u gosod yn unol â chyfarwyddyd y gwneuthurwr.
- Ni 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.
- To Comply with Section 91 (as amended) of the Town and Country Planning Act 1990.
- I gydymffurfio a Rhan 91 (fel y diwygiwyd) o'r Ddeddf Gynllunio Gwlad a Thref 1990.
- To define the permission and for the avoidance of doubt.
- Er mwyn diffinio’r caniatâd ac i osgoi amheuaeth.
- To secure biodiversity enhancement in accordance with Strategic Policy D of the adopted Eryri Local Development Plan and paragraph 6.4.5 of Planning Policy Wales.
- To prevent hydraulic overloading of the public sewerage system, to protect the health and safety of existing residents and ensure no pollution of or detriment to the environment.
- 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 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.
- 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 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.
- Nodiadau Cynghori 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 (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 a chadw systemau draenio d"{r wyneb'. 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 berthnasol yr Awdurdod Lleol i drafod eu gofynion effeithlonrwydd d"{r.
