Rwy'n cydnabod y gwaith a wnaed yn Ynysforgan, mewn gwirionedd. Cafodd tua 300 o gartrefi eu diogelu yno. Eto i gyd, yn y blynyddoedd diwethaf, rydym hefyd wedi gweld adeiladu newydd ar safleoedd sy'n ymddangos fel pe baent ar dir isel yn agos at yr afon. Ar y llaw arall, yn fy ngwaith blaenorol, rwy'n cofio gorfod esbonio i fenthycwyr dro ar ôl tro, er bod eu chwiliadau amgylcheddol yn dangos bod tai'n cael eu hadeiladu ar orlifdiroedd, nid oedd hynny'n wir - roeddent fel arfer sawl metr yn uwch nag y dangosai mapiau risg gorlifdiroedd amgylcheddol, a byddai wedi cymryd tswnami, mewn gwirionedd, i orlifo i'r rhan fwyaf ohonynt. Pa mor aml y caiff y cynlluniau gorlifdir hyn eu hailasesu? Rwy'n gofyn nid yn unig am y gall astudiaethau bwrdd gwaith fethu nodi daearyddiaeth leol yn aml, os mynnwch, ond hefyd am y gall gorddatblygu mewn ardal benodol effeithio ar lefel trwythiad a dŵr ffo, ac mae hynny'n arbennig o bwysig mewn llefydd fel Abertawe, lle rydym yn edrych ar 20,000 o gartrefi newydd, yn ogystal â'r seilwaith cysylltiedig.

I acknowledge the work that was done in Ynys Forgan, really. That's about 300 homes that were protected there. Yet, in recent years, we've also seen new building on sites on seemingly low-level ground close to the river. Conversely, in my previous work, I recall having to repeatedly explain to lenders that, while their environmental searches revealed that properties were being built in floodplain areas, it wasn't the case - they were usually several metres higher than the environmental floodplain risk maps revealed, and it would've taken a tsunami, actually, to have taken most of them out. How often are these floodplain plans reassessed? I ask not just because desktop studies can often miss local geography, if you like, but also because overdevelopment in a particular area can affect the water table and water run-off, and that's particularly important in places like Swansea, where we're looking at 20,000 new homes, as well as the associated infrastructure.

Yng Nghymru, wrth gwrs, y mae'r nifer mwyaf a gofnodwyd o blant sy'n derbyn gofal. Roedd 6,845 o blant ar 31 Mawrth eleni, cynnydd o 65 y cant ers 2003. Bu'r newid yn fwy dybryd fyth mewn rhai awdurdodau lleol penodol megis Ynys Môn, gyda chynnydd o 190 y cant, Torfaen 195 y cant, a 250 y cant yn sir Fynwy. At hynny, roedd gan Gaerdydd 380 yn fwy o blant yn derbyn gofal eleni, gan dynnu sylw at yr hyn sy'n parhau i fod yn duedd sy'n peri pryder yn ein cymunedau. Felly, nid yw'n syndod Dirprwy Weinidog, fy mod yn sicr yn diolch ichi am yr adroddiad a'r cyfle inni drafod hyn.

Wales, of course, has the highest number of looked-after children on record. There were 6,845 children as of 31 March this year, a 65 per cent increase since 2003. The change has been even more extreme in some particular local authorities such as Anglesey, seeing a 190 per cent increase, Torfaen 195 per cent, and Monmouthshire 250 per cent. Moreover, Cardiff had 380 more looked-after children to care for this year, highlighting what continues to be a worrying trend in our communities. So, it comes as no surprise, therefore, Deputy Minister, that I certainly thank you for the report and the opportunity for us to debate this.

Diolch, Caroline. Mae gan swyddogion iechyd yr amgylchedd bŵer i gyhoeddi hysbysiadau cosb benodedig neu argymell erlyniad. Gallant gyhoeddi hysbysiadau gwella neu gau adeiladau am dorri rheoliadau coronafeirws ac o 14 Medi ymlaen, gallant gau safleoedd, digwyddiadau neu fannau cyhoeddus ar sail iechyd y cyhoedd. Mae gan yr heddlu bwerau gorfodi hefyd os nad yw pobl yn ymateb i swyddogion iechyd yr amgylchedd.

Thank you, Caroline. Environmental health officers have the power to issue fixed-penalty notices or recommend prosecution. They can issue premises improvement or closure notices for breaches of the coronavirus regulations and, from 14 September, they can close premises, events or public places on public health grounds. The police also have enforcement powers if people don't respond to the environmental health officers.

Diolch. Y cyfan sydd ei angen mewn gwirionedd yw i'r Llywodraeth ddiddymu rhyddhad ardrethi ar dai i fusnesau bach.

Thank you. All it really needs is for the Government to abolish small business rates relief on houses.

Awn ni ymlaen, felly, at yr ail eitem, sef i nodi cofnodion y cyfarfod a gynhaliwyd ar 14 Medi 2020. Dwi'n tybio bod Aelodau'n hapus i nodi'r cofnodion. Ie. Diolch yn fawr iawn.

We'll go on, therefore, to the second item, which is to note the minutes of the meeting held on 14 September 2020. I suspect that Members will be happy to note those minutes. Yes. Thank you very much.
