ANGUS LOCAL PLAN REVIEW FINALISED PLAN - Angus Council

(a) the supply is certified fit for human consumption by theEnvironmental and Consumer Protection Department ofAngus Council; and(b) abstraction rates from the source will not contaminate ordeplete the supply to the detriment of existing users.Flood Risk3.53 Parts of Angus, principally around lochs, rivers andwatercourses, are prone to localised flooding as a consequence ofperiods of heavy rainfall or rapid snow melt. In addition some lowlying areas may be at risk from flooding due to tidal influence andwave action. Climate change is likely to have an increasing impact onboth flooding and sea level rise over the life of this Local Plan. Recenttrends show increasing levels of rainfall with storms likely to becomemore frequent and unpredictable. While flood events are most likelyto occur along the North Esk, South Esk, Brothock Water, parts of theElliot Water, and catchment of the Dighty Water and its tributaries,low-lying areas adjacent to other watercourses, such as the BarryBurn, can also be prone to localised flooding.SPP7: Planning and Flooding(2004):The central purpose of theGovernments Policy is toprevent further developmentwhich would have a significantprobability of being affected byflooding or which would increasethe probability of floodingelsewhere.Planning authorities must takethe probability of flooding fromall sources and the risksinvolved into account during thepreparation of developmentplans and in determiningplanning applications.3.54 The effects of natural flood events can be compounded bysurface water run-off from developed areas and the amount ofexisting development in low-lying areas at risk from flooding. It istherefore important when assessing development proposals oroptions for future development land that the potential for floodingshould be minimised by taking full account of flood risk, both on siteand elsewhere in the local catchment area.3.55 The Angus Flood Liaison and Advice Group has considered thepotential for flooding in Angus taking into account flood frequencyinformation provided by SEPA which identified those areas mostsusceptible to flood risk. As a general principle there will be apresumption against locating ‘built’ development in areas of knownsignificant flood risk. A precautionary principle will be adopted inconsidering development options or proposals in flood plains and lowlyingareas adjacent to watercourses.Flood Liaison and AdviceGroup (FLAG):A non-statutory advisory groupof public and private sectorrepresentatives, convened byCouncils to share concerns andknowledge and provide adviceon a wide range of planning andother flooding issues.3.56 Where development is proposed, an assessment of thepotential for flooding will be required, taking account of the location ofthe site and the flow characteristics of the local watercourse. Whereappropriate, developers will be required to provide a detailed floodrisk assessment in support of a planning application. SPP7: Planningand Flooding includes a Risk Framework based on flood returnperiods for coastal, tidal and watercourse flooding that provides abasis for assisting the assessment of development proposals in areasknown or suspected to be at risk from flooding.3.57 Angus Council will consult SEPA on all development proposalsin areas known to be subject to flooding. To minimise the risk oflocalised flooding, surface water run-off from all new development willbe managed using Sustainable Urban Drainage Systems (SUDS) asspecified by Policy ER23 above.Angus Local Plan Review77Finalised Plan
