Table 7-17: SWDP8/2 (Temple Laugherne – Worcester West urban expansion)OS NGR: SO 820534 Area: 77.79ha Brown/Greenfield: GreenfieldFlood Zone Coverage: FZ3a: 1% FZ3b: 6% FZ2: 1% FZ1: 92%Exception Test required? Yes, for More Vulnerable and Essential Infrastructure developmentin FZ3a and for Highly Vulnerable development in FZ2.Highly Vulnerable infrastructure should not be permitted within FZ3a. More Vulnerable and LessVulnerable Infrastructure should not be permitted within FZ3b.Requirements for passing the Exception Test:To pass Part ‘b’ of the Exception Test, a FRA should demonstrate that: thedevelopment will be safe, will avoid increasing flood risk elsewhere, and will reduceflood risk overall.Preference should be given to water compatible and less vulnerable development atthis site. Development should be located away from the unnamed tributaries of theLaughern Brook, confined to the lakes and channels to the north, west and centralparts of the site and Flood Zone 2 and 3, by using sequential design to locate morevulnerable development towards higher ground, through building design, and bymeeting drainage requirements.New development being located outside of Flood Zone 2 and 3 needs to ensure thatno increase in flood risk occurs. Areas within Flood Zone 2 should be kept as openspace, with the potential for a buffer.Safe access and egress would need to be demonstrated.Consultation with the Local Authority and the Environment Agency should beundertaken at an early stage.2012s5947 S Worcestershire Level 2 SFRA Update FINAL Report v1.0.doc 90
Sources of Flood Risk:Primary flood risk to the site is fluvial, resulting from overtopping of the unnamedtributaries of the Laughern Brook, confined to the lakes and channels to the north,west and central parts of the site. The central and northern parts of the site fallswithin Flood Zone 3b and the Blue Zone of the Policy Maps. The right arm of theA44 Bromyard road, the A4440 Grove Way, Tudor Way and the Oldbury road, someof the main access roads to the site, are at risk from fluvial flooding.Surface water presents a risk to the site. Further development and creation ofimpermeable surfaces may result in an increase of surface water flood risk. The2012s5947 S Worcestershire Level 2 SFRA Update FINAL Report v1.0.doc 91
