5 Things You Need to Know about Environmental Agency\u2019s new climate change allowances<\/strong><\/p>\n

Did you know that in February of this year the Environment Agency (EA) changed the way it views climate change and how it will affect flood risk? These changes will have a widespread and immediate effect on planning applications. So what do you need to know<\/p>\n

1\u00a0\u00a0\u00a0 Climate change has gone regional.<\/strong><\/p>\n

Gone is the national blanket 20% increase allowance in river flooding and in is a regional view, based on 11 river basin districts. Want to find out which area you\u2019re in? Use the EA\u2019s catchment data search using place name or postcode here http:\/\/environment.data.gov.uk\/catchment-planning\/<\/span><\/a><\/p>\n

2\u00a0\u00a0\u00a0 Climate change views have changed for rivers and rainfall<\/strong><\/p>\n

Flooding from the sea, however, is currently thought to be largely unchanged (although there is some changes to how many storms are predicted and how high waves will be during storms).<\/p>\n

3\u00a0\u00a0\u00a0 What, Where and How Long For? These things now matter!<\/strong><\/p>\n

Climate change allowances now take into account what you\u2019re building, how long the structure will be around and where you\u2019re building it.<\/p>\n

Homes tend to be classified as \u2018more vulnerable\u2019<\/em> and are designed to last longer, whereas offices and warehouses tend to be classified \u2018less vulnerable\u2019<\/em> and have shorter lifespans. Now climate change allowances take this and the area in which you\u2019re building into account by splitting climate change into 3 different timeframes (2015 \u2013 2039; 2040 \u2013 2069; and 2070 \u2013 2115) and 3 different brackets (central, higher central and upper end).<\/p>\n

For example, using the tables below we can see that to build a new home in the South East in flood zone 3a, you will need to potentially add up to 105% onto the existing river flows to account for climate change up to 2115. However, if you wish to build a warehouse, then you will only need to add 30% to look to 2069. Agreements as to which flows to be adopted should be discussed with the EA. The reasoning is that for when we focus on residential dwellings \u2018More Vulnerable\u2019<\/em> they fall into the \u2018Higher Central and Upper End\u2019<\/em> bracketing therefore the flows to be adopted could be 50% to potentially 105%. The effect on the flood plain these flows can have could differentiate whether a development is viable.<\/p>\n

Table below shows peak river flow allowances by river basin district for South East and Thames<\/em><\/p>\n

4\u00a0\u00a0\u00a0 There\u2019ll be significant changes to large developments.<\/strong><\/p>\n

There\u2019s a greater focus on larger developers re-modelling the flood risks posed by climate change. However, the Environment Agency are open to discussion for small developments as to how to best address climate change without having to re-model. Please do not hesitate to contact our team on how best to address smaller developments.<\/p>\n
