English: Where such policies are considered appropriate it should be made clear that the release of small housing sites within or adjoining existing settlements for the provision of affordable housing to meet local needs which would not otherwise be allocated in the development plan, is an exception to the policies for general housing provision.
Welsh: Os credir bod y cyfryw bolisïau yn briodol, dylid nodi yn eglur bod rhyddhau safleoedd bach mewn aneddiadau presennol, neu am y ffin â hwy, sef safleoedd na chaent eu neilltuo fel arall yn y cynllun datblygu, at ddiben datblygu tai fforddiadwy i ddiwallu anghenion lleol, yn eithriad i'r polisïau ar gyfer y ddarpariaeth gyffredinol o dai.
English: Such policies must be fully justified, setting out the type of need and the kind of development which fall within their terms.
Welsh: Rhaid cyfiawnhau polisïau o'r fath yn llawn gan nodi'r math o angen a'r math o ddatblygiad sy'n dod o fewn eu telerau.
English: The affordable housing provided on exception sites should meet the needs of local people in perpetuity.
Welsh: Dylai'r tai fforddiadwy a ddarperir ar y cyfryw safleoedd ddiwallu anghenion pobl leol am byth.
English: Sites must meet all the other criteria against which a housing development would be judged.
Welsh: Rhaid i'r safleoedd gwrdd â'r holl feini prawf eraill ar gyfer barnu datblygiadau tai.
English: Affordable housing exception sites are not appropriate for market housing.
Welsh: Nid yw safleoedd eithriedig tai fforddiadwy yn briodol ar gyfer tai ar y farchnad agored.
English: Gypsies and Travellers
Welsh: Sipsiwn a Theithwyr
English: Where a Gypsy and Traveller Accommodation Assessment (GTAA) identifies an unmet need, a planning authority should allocate sufficient sites in their development plan to ensure that the identified pitch requirements for residential and/or transit use can be met.
Welsh: Os yw Asesiad o Anghenion Llety Sipsiwn a Theithwyr yn nodi angen nas diwallwyd, dylai awdurdod cynllunio neilltuo digon o safleoedd yn ei gynllun datblygu er mwyn sicrhau bod modd bodloni'r gofynion safle dynodedig ar gyfer defnydd preswyl a/neu dramwy.
English: Planning authorities will need to demonstrate that sites are suitable for development and deliverable in the identified timescales
Welsh: Bydd angen i awdurdodau cynllunio ddangos bod safleoedd yn addas ar gyfer eu datblygu a bod modd eu darparu yn unol â'r amserlenni a nodwyd
English: In drawing up policies planning authorities should consult providers of social housing, representatives of Gypsies and Travellers communities and landowners in areas likely to be appropriate for site provision.
Welsh: Wrth lunio polisïau, dylai awdurdodau cynllunio ymgynghori â darparwyr tai cymdeithasol, cynrychiolwyr cymunedau Sipsiwn a Theithwyr a thirfeddianwyr mewn ardaloedd sy'n debygol o fod yn briodol ar gyfer darparu safleoedd.
English: The consultation should be undertaken in a manner that is consistent with the planning authority's Community Involvement Scheme.
Welsh: Dylid cynnal yr ymgynghoraid mewn ffordd sy'n gyson â Chynllun Cynnwys Cymunedau'r awdurdod cynllunio.
English: The assessment of Gypsy and Traveller accommodation needs, and the duty to make provision for sites where the assessment identifies need, are statutory requirements under the Housing (Wales) Act 2014.
Welsh: Mae asesu anghenion llety teuluoedd Sipsiwn a Theithwyr, a'r ddyletswydd i ddarparu safleoedd os yw asesiad yn nodi angen o'r fath, yn ofynion statudol bellach o dan Ddeddf Tai (Cymru) 2014.
English: Further detail on the process of providing Gypsy and Traveller sites through the planning system is contained in Welsh Government Circular

Welsh: Cynllunio ar gyfer Safleoedd Sipsiwn, Teithwyr a Siewmyn
English: Rural enterprise dwellings represent one of the few circumstances in which isolated new residential development in the open countryside may be justified.
Welsh: Mae anheddau menter wledig yn un o'r ychydig enghreifftiau lle mae modd cyfiawnhau datblygiad preswyl newydd ynysig yng nghefn gwlad agored.
English: It will be important to establish whether the rural enterprise is operating as a business and will continue to operate for a reasonable length of time.
Welsh: Bydd yn bwysig penderfynu a ydy'r fenter wledig yn gweithredu fel busnes ac a fydd yn parhau i weithredu am gyfnod rhesymol.
English: Planning authorities should follow the guidance in Technical Advice Note (TAN) 6:
Welsh: Dylai awdurdodau cynllunio ddilyn y canllawiau sydd yn Nodyn Cyngor Technegol (TAN) 6:
English: Planning for Sustainable Rural Communities
Welsh: Cynllunio ar gyfer Cymunedau Gwledig Cynaliadwy
English: Applications for rural enterprise dwellings must only be permitted where the rural enterprise dwelling appraisal provides conclusive evidence of the need for the dwelling.
Welsh: Ni ddylid caniatáu ceisiadau ar gyfer anheddau menter wledig oni bai bod yr arfarniad o'r annedd menter wledig yn darparu tystiolaeth bendant o'r angen am annedd.
English: In order to ensure that rural enterprise dwellings are retained for their intended purpose a condition restricting the occupancy of the property must be applied.
Welsh: Er mwyn sicrhau bod anheddau menter wledig yn cael eu cadw at y diben y'u bwriadwyd, rhaid rhoi amod sy'n cyfyngu ar feddiannaeth yr eiddo.
English: Rural enterprise dwellings should also be classified as affordable housing as defined in TAN 2: Planning and Affordable Housing, to ensure that the dwelling remains available to meet local affordable housing need should the original justification cease to exist.
Welsh: Hefyd, dylid diffinio anheddau menter wledig fel tai fforddiadwy yn unol â diffiniad TAN 2, Cynllunio a Thai Fforddiadwy, er mwyn sicrhau bod yr annedd ar gael o hyd i ddiwallu anghenion tai fforddiadwy lleol os nad yw'r cyfiawnhad gwreiddiol yn berthnasol bellach.

English: One Planet Development
Welsh: Datblygiad Un Blaned
English: OPD may take a number of forms and can either be single homes, co-operative communities or larger settlements.
Welsh: Gall Datblygiadau Un Blaned fod ar amryw o ffurfiau a gallant fod yn gartrefi ar eu pennau eu hunain, yn gymunedau cydweithredol neu'n aneddiadau mwy o faint.
English: They may be located within or adjacent to existing settlements, or be situated in the open countryside.
Welsh: Gallant fod yn rhan o aneddiadau presennol, neu fod ar y ffin â hwy, neu fod yng nghefn gwlad agored.
English: This should be evidenced by a management plan produced by a competent person (s).
Welsh: Dylid dangos hyn trwy gynllun rheoli a luniwyd gan berson (au) cymwys.
English: Where this cannot be demonstrated, proposals should be considered against policies which seek to control development in the open countryside.
Welsh: Os nad oes modd dangos hyn, dylai cynigion gael eu hystyried yn erbyn polisïau sy'n ceisio rheoli datblygiad yng nghefn gwlad agored.
English: Planning authorities should follow the guidance in TAN 6

English: Activities in a Place
Welsh: Gweithgareddau Mewn Lle
English: They are highly accessible to different modes of transport and are the most sustainable locations for new development.
Welsh: Mae modd defnyddio dulliau gwahanol o drafnidiaeth i'w cyrraedd, a'r canolfannau hyn yw'r lleoliadau mwyaf cynaliadwy ar gyfer datblygiad newydd.
English: Opportunities to live in these centres, combined with their good public transport links, make them the most sustainable places.
Welsh: Mae cyfleoedd i fyw yn y canolfannau hyn, ynghyd â'u cysylltiadau trafnidiaeth gyhoeddus da, yn golygu mai nhw yw'r lleoedd mwyaf cynaliadwy.
English: The planning system must:
Welsh: Mae'n rhaid i'r system gynllunio:
English: promote viable urban and rural retail and commercial centres as the most sustainable locations to live, work, shop, socialise and conduct business;
Welsh: hyrwyddo canolfannau manwerthu a masnachol trefol a gwledig hyfyw fel y lleoliadau mwyaf cynaliadwy i fyw, gweithio, siopa, cymdeithasu a chynnal busnes;
English: sustain and enhance retail and commercial centres' vibrancy, viability and attractiveness; and
Welsh: cynnal a gwella bywiogrwydd, hyfywedd a dengarwch canolfannau manwerthu a masnachol; a
English: iImprove access to, and within, retail and commercial centres by all modes of transport, prioritising walking, cycling and public transport.
Welsh: gwella mynediad at, ac o fewn, canolfannau manwerthu a masnachol drwy bob math o drafnidiaeth, gan roi blaenoriaeth i gerdded, beicio a thrafnidiaeth gyhoeddus.
English: Retail Strategies
Welsh: Strategaethau Manwerthu
English: The strategy and policies should set out a framework for the future of retail and commercial centres in their area, taking in to account strategies in adjoining authorities, to promote a successful retailing sector supporting existing and new communities.
Welsh: Dylai'r strategaeth a'r polisïau lunio fframwaith ar gyfer dyfodol canolfannau manwerthu a masnachol yn yr ardal, gan ystyried strategaethau awdurdodau cyfagos, er mwyn hyrwyddo sector manwerthu llwyddiannus sy'n cefnogi cymunedau presennol a newydd.
English: In some situations it may be necessary to take pro-active steps to identify retail and commercial centre locations for expansion.
Welsh: Mewn rhai sefyllfaoedd, efallai y bydd angen cymryd camau rhagweithiol i nodi lleoliadau ar gyfer ehangu canolfannau manwerthu a masnachol.
English: In others it may be necessary to identify measures to reinvigorate centres or to manage a change in the relative importance of a centre as other centres' roles expand.
Welsh: Mewn eraill efallai y bydd angen nodi mesurau i adfywio canolfannau neu i reoli newid ym mhwysigrwydd cymharol canolfan wrth i rolau canolfannau eraill ehangu.
English: Strategies and supporting policies should be based on robust evidence.
Welsh: Dylai strategaethau a pholisïau cysylltiedig fod yn seiliedig ar dystiolaeth gadarn.
English: In developing strategies, plans and policies to revitalise and increase the attractiveness of existing retail and commercial centres, planning authorities should consult the private sector and local communities.
Welsh: Wrth ddatblygu strategaethau, cynlluniau a pholisïau i adfywio canolfannau sy'n bodoli eisoes a'u gwneud yn fwy deniadol, dylai awdurdodau cynllunio ymgynghori â'r sector preifat a chymunedau.
English: Retail and Commercial Centre Hierarchies
Welsh: Hierarchaethau Canolfannau Manwerthu a Masnachol
English: The planning authority should consider the characteristics of each type of centre so they can be consistently categorised.
Welsh: Dylai'r awdurdod cynllunio ystyried nodweddion pob math o ganolfan er mwyn sicrhau cysondeb wrth eu categoreiddio.
English: For example, this could be the range of uses present or the extent of the catchment area.
Welsh: Er enghraifft, y defnyddiau amrywiol neu ffiniau'r dalgylch.
English: The hierarchy should distinguish between higher order centres which have a wider range of uses and larger catchment areas, and lower order centres which are important to communities for day-to-day needs.
Welsh: Dylai'r hierarchaeth wahaniaethu rhwng y canolfannau uwch sydd ag amrywiaeth ehangach o ddefnyddiau a dalgylchoedd mwy o faint, a'r canolfannau is sy'n bwysig i gymunedau o ran eu hanghenion o ddydd i ddydd.
English: Evidence should demonstrate whether retail provision is adequate or not, by assessing if there is further expenditure capacity in a catchment area (quantitative need) or if there is a lack of retail quality, range of goods or accessibility (qualitative need).
Welsh: Dylai tystiolaeth ddangos a yw darpariaeth fanwerthu yn ddigonol ai peidio, drwy asesu a oes rhagor o gapasiti gwario mewn dalgylch (angen meintiol) neu a oes prinder ansawdd, ystod nwyddau neu hygyrchedd manwerthu (angen ansoddol).
English: However, there is no requirement to demonstrate the need for developments within defined retail and commercial centre boundaries or sites allocated in a development plan for specific retail uses.
Welsh: Fodd bynnag, nid oes angen dangos yr angen am ddatblygiadau oddi mewn i ffiniau neu safleoedd canolfannau manwerthu a masnachol diffiniedig sydd wedi'u neilltuo mewn cynllun datblygu ar gyfer defnyddiau manwerthu penodol.
English: This approach reinforces the role of centres, and other allocated sites, as the best location for most retail, leisure, and commercial activities.
Welsh: Mae'r dull gweithredu hwn yn atgyfnerthu rôl canolfannau, a safleoedd eraill sydd wedi'u neilltuo, fel y lleoliad gorau ar gyfer y rhan fwyaf o weithgareddau manwerthu, hamdden a masnachol.
English: It is not the role of the planning system to restrict competition between retailers within centres.
Welsh: Nid rôl y system gynllunio yw cyfyngu ar gystadleuaeth rhwng manwerthwyr mewn canolfannau.
English: Precedence should be given to establishing quantitative need before qualitative need is considered for both convenience and comparison floorspace, particularly as a basis for development plan allocations.
Welsh: Dylid rhoi blaenoriaeth i gadarnhau beth yw'r angen meintiol cyn ystyried yr angen ansoddol, a hynny o ran arwynebedd llawr lle gwerthir nwyddau cyfleus ac arwynebedd lle gwerthir nwyddau a gymerir, yn enwedig fel sail i ddyraniadau mewn cynlluniau datblygu.
English: supports the objectives and retail strategy of an adopted development plan or the policies in this guidance;
Welsh: cefnogi amcanion a strategaeth fanwerthu cynllun datblygu mabwysiedig neu'r polisïau yn y canllawiau hyn;
English: is highly accessible by walking, cycling or public transport;
Welsh: hygyrch iawn drwy gerdded, drwy feicio neu ar drafnidiaeth gyhoeddus;
English: contributes to a substantial reduction in car journeys;
Welsh: cyfrannu at ostyngiad sylweddol yn nifer y teithiau mewn ceir;
English: contributes to the co-location of facilities in existing retail and commercial centres;
Welsh: cyfrannu at gydleoli cyfleusterau mewn canolfannau manwerthu a masnachol sy'n bodoli'n barod;
English: significantly contributes to the vibrancy, attractiveness and viability of such a centre;
Welsh: cyfrannu'n sylweddol at fywiogrwydd, dengarwch a hyfywedd canolfan o'r fath;
English: assists in the alleviation of over-trading of, or traffic congestion surrounding, existing local comparable stores;
Welsh: cynorthwyo i liniaru gorfasnachu, neu dagfeydd traffig o amgylch, siopau cyffelyb lleol sy'n bodoli'n barod;
English: addresses locally defined deficiencies in provision in terms of quality and quantity, including that which would serve new residential developments; or where it;
Welsh: mynd i'r afael â diffygion, a ddiffiniwyd yn lleol, o ran ansawdd a maint y ddarpariaeth, gan gynnwys yr hyn a fyddai'n gwasanaethu datblygiadau preswyl newydd; neu os yw'n; a
English: alleviates a lack of convenience goods provision in a disadvantaged area.
Welsh: lliniaru diffyg darpariaeth o ran siopau cyfleustra mewn ardal ddifreintiedig.
English: Regeneration and additional employment benefits are not considered qualitative need factors in retail policy terms.
Welsh: Nid yw buddiannau o ran adfywio a chyflogaeth ychwanegol yn cael eu hystyried yn ffactorau wrth asesu'r angen ansoddol o ran polisi manwerthu.
English: However, they may be material considerations in making a decision on individual planning applications if the regeneration and job creating benefits can be evidenced.
Welsh: Fodd bynnag, gallant fod yn ystyriaethau perthnasol wrth wneud penderfyniad ar geisiadau cynllunio unigol os gellir dangos tystiolaeth o'u buddiannau o ran adfywio a chreu swyddi.
English: If there is no quantitative or qualitative need for further development for retail and commercial centre uses, there will be no need to identify additional sites.
Welsh: Os nad oes unrhyw angen meintiol neu ansoddol am ragor o ddatblygiad ar gyfer defnyddiau canolfannau manwerthu a masnachol, ni fydd angen nodi safleoedd ychwanegol.
English: In implementing this policy, planning authorities should adopt a sequential approach to the selection of new sites in their development plan and when determining planning applications for retail and other complementary uses.
Welsh: Wrth roi'r polisi hwn ar waith, dylai awdurdodau cynllunio fabwysiadu dull cymalog o ddewis safleoedd newydd yn eu cynllun datblygu ac wrth benderfynu ceisiadau cynllunio ar gyfer defnyddiau manwerthu a defnyddiau ategol eraill.
English: By adopting a sequential approach first preference should be to locate new development within a retail and commercial centre defined in the development plan hierarchy of centres.
Welsh: Wrth fabwysiadu dull cymalog, dylid rhoi blaenoriaeth i leoli datblygiadau newydd mewn canolfan fanwerthu a masnachol sydd wedi'i diffinio yn hierarchaeth canolfannau'r cynllun datblygu.
English: Developers should demonstrate that all potential retail and commercial centre options, and then edge-of-centre options, have been thoroughly assessed using the sequential approach before out-of-centre sites are considered.
Welsh: Dylai datblygwyr ddangos bod yr holl ddewisiadau posibl o ran canolfannau manwerthu a masnachol, ac yna'r dewisiadau ar gyrion y canol, wedi cael eu hasesu'n drylwyr gan ddefnyddio'r dull cymalog cyn ystyried safleoedd y tu allan i'r canol.
English: The onus of proof that central sites have been thoroughly assessed rests with the developer.
Welsh: Cyfrifoldeb y datblygwr yw profi bod safleoedd canolog wedi cael eu hasesu'n drylwyr.
English: New out-of-centre retail developments or extensions to existing out-of-centre developments should not be of a scale, type or location likely to undermine the vibrancy, attractiveness and viability of those retail and commercial centres that would otherwise serve the community, and should not be allowed if they would be likely to put development plan retail strategy at risk.
Welsh: Ni ddylai datblygiadau manwerthu newydd y tu allan i'r canol nac estyniadau i ddatblygiadau sy'n bodoli eisoes y tu allan i'r canol fod ar raddfa nac o fath nac mewn lleoliad sy'n debygol o danseilio bywiogrwydd, dengarwch a hyfywedd canolfannau manwerthu a masnachol a fyddai fel arall yn gwasanaethu'r gymuned, ac ni ddylid eu caniatáu os ydynt yn debygol o beryglu'r strategaeth fanwerthu yn y cynllun datblygu.
English: The extent of a sequential test should be agreed by pre-application discussion between the planning authority and the developer.
Welsh: Dylai graddfa prawf cymalog gael ei chytuno mewn trafodaeth cyn cyflwyno cais rhwng yr awdurdod cynllunio a'r datblygwr.
English: Other complementary uses include, for example, financial and professional services (A2), food and drink (A3), offices (B1), hotels (C1), educational and other non-residential establishments (D1), leisure (D2) and certain other uses such as launderettes and theatres
Welsh: Mae defnyddiau ategol eraill yn cynnwys, er enghraifft, gwasanaethau ariannol a phroffesiynol (A2), bwyd a diod (A3), swyddfeydd (B1), gwestai (C1), sefydliadau addysgol a dibreswyl eraill (D1), hamdden (D2) a rhai defnyddiau eraill fel golchdai a theatrau
English: However, some education, healthcare and community uses may have specific accessibility requirements which mean they need to be located close to the communities they serve.
Welsh: Fodd bynnag, mae'n bosibl y bydd gan rai defnyddiau addysg, gofal iechyd a chymunedol ofynion hygyrchedd penodol sy'n golygu bod angen eu lleoli'n agos i'r cymunedau a wasanaethant.
English: Planning authorities should be flexible in their approach where it is necessary.
Welsh: Dylai awdurdodau cynllunio fod ag agwedd hyblyg os oes angen.
English: The nature of a proposed use is likely to determine what type of centre (i.e. higher or lower order centre) is most appropriate as a starting point for the sequential approach process.
Welsh: Mae natur y defnydd arfaethedig yn debygol o benderfynu pa fath o ganolfan (h.y. canolfan uwch neu ganolfan is) sy'n addas fel man cychwyn proses y dull cymalog.
English: The Town and Country (Use Classes) Order 1987 (as amended) puts uses of land and buildings into various categories known as 'Use Classes'.
Welsh: Mae Gorchymyn Gwlad a Thref (Dosbarthau Defnydd) 1987 (fel y'i diwygiwyd) yn rhannu defnyddiau tir ac adeiladau yn gategorïau o'r enw 'Dosbarthau Defnydd'.
English: In allocating sites for different types of retail and commercial centre uses planning authorities should take account of factors such as floorspace, quality, convenience, traffic generation and attractiveness of the site.
Welsh: Wrth ddyrannu safleoedd ar gyfer mathau gwahanol o ddefnydd canolfannau manwerthu a masnachol, dylai awdurdodau cynllunio ystyried ffactorau fel arwynebedd llawr, ansawdd, cyfleustra, y traffig sy'n cael ei greu a natur ddeniadol y safle.
English: Planning authorities should not prescribe rigid floorspace limits on allocated sites that would unreasonably inhibit the retail industry from responding to changing demand and opportunity.
Welsh: Ni ddylai awdurdodau cynllunio ragnodi terfynau caeth o ran arwynebedd llawr ar safleoedd a neilltuwyd, a fyddai'n atal y diwydiant manwerthu mewn ffordd afresymol rhag ymateb i newid yn y galw ac i gyfleoedd.
English: Where this is the case such stores should in the first instance be located on sites identified for such a purpose in the development plan, preferably on an edge of centre site.
Welsh: Mewn achosion o'r fath, dylai siopau o'r fath gael eu lleoli yn y lle cyntaf ar safleoedd a nodwyd at ddiben o'r fath yn y cynllun datblygu, ar safle ar gyrion canolfan os oes modd.
English: Where such sites are not available or suitable, other sites at the edge of retail and commercial centres, followed by out-of-centre locations may be considered, subject to application of the needs and impact tests.
Welsh: Os nad oes safleoedd o'r fath ar gael nac yn addas, gellir ystyried safleoedd eraill ar gyrion canolfannau manwerthu a masnachol, ac yna lleoliadau y tu allan i'r ganolfan, yn amodol ar ganlyniadau'r prawf angen a'r prawf effaith.
English: However, where a planning authority has evidence an existing retail site is no longer required for the use it was intended, the authority should consider what alternative uses may be appropriate and include policies in its plan.
Welsh: Fodd bynnag, lle bo gan awdurdod cynllunio dystiolaeth nad oes angen safle manwerthu mwyach at y diben y'i bwriadwyd, dylai'r awdurdod ystyried pa ddibenion eraill allai fod yn briodol a chynnwys polisïau yn ei gynllun.
English: Retail Impact Assessments
Welsh: Asesiadau Effaith Manwerthu
English: Impacts resulting from such development, whether individual or cumulative, may include changes in turnover and trading ability, consumer choice, traffic and travel patterns, footfall, as well as affect centre regeneration strategies and existing or proposed retail sites allocated in the development plan.
Welsh: Gall canlyniadau unigol neu gronnus datblygiadau o'r fath gynnwys newidiadau mewn trosiant a gallu masnachu, dewis defnyddwyr, patrymau traffig a theithio, nifer yr ymwelwyr, gan effeithio ar strategaethau adfywio canolfannau a safleoedd manwerthu presennol neu arfaethedig a ddyrannwyd yn y cynllun datblygu.
English: The purpose of the retail impact assessment is to consider these issues and determine if these developments are likely to have detrimental consequences.
Welsh: Diben yr asesiad effaith manwerthu yw ystyried y materion hyn a phenderfynu a yw'r datblygiadau hyn yn debygol o arwain at ganlyniadau niweidiol.
English: Requests for retail impact assessments by planning authorities on smaller developments should be proportionate to potential impacts.
Welsh: Dylai ceisiadau am asesiadau effaith manwerthu gan awdurdodau cynllunio ar ddatblygiadau llai o faint fod yn gymesur â'r effeithiau posibl.
