Key adaptation principles for planning UKCIP Seek opportunities to incorporate adaptation measures into new and existing developments Work in partnership with communities Incorporate flexibility to deal with changing risks Understand existing vulnerabilities to climate and identify critical thresholds Identify key climate risks using the latest climate change projections Adopt a sequential and risk-based approach to development decisions Review your strategy regularly
Key adaptation principles for planning UKCIP Do nothing this may be an appropriate response to low priority impacts or situations where climate risks are outweighed by nonclimate factors No regret options will deliver benefits that exceed their costs, whatever the extent of climate change Low regret low-cost options that have potentially large benefits in future Win-win options are ones that contribute to desired outcomes (be they environmental, social or economic), and also improve your ability to adapt to climate risks Avoid actions that will make it more difficult to cope with climate risks in the future
Adaptation planning at different spatial UKCIP scales Conurbation or catchment scale Offers opportunities for integrated approaches to adaptation covering a mix of land uses over large areas Neighbourhood scale Discrete groups of dwellings or mixed use buildings. Needs consideration of adapting the public realm and spaces between buildings Building scale Smaller developments and individual buildings. Needs consideration of design of the building, its surroundings and how it is used and managed

Adaptation planning at different spatial UKCIP scales Levers, influence and policies We have identified some of the physical adaptation strategies that might be deployed in response to different climatic conditions We will now consider the mechanisms available to spatial planners to encourage or require such adaptations to be implemented. Working in table groups consider the adaptation responses indicated on each slide, discuss implications for policy and DC. and suggest ways in which they could be encouraged.
SUDS and Green infrastructure
SUDS Sustainable drainage systems UKCIP Some key principles storing runoff and releasing it slowly (attenuation) allowing water to soak into the ground (infiltration) Slowly transporting (conveying) water on the surface filtering out pollutants allowing sediments to settle out by controlling the flow of the water Source: http://www.ciria.com/suds/suds_principles.htm
