Table 7-24: SWDP13/4 (Former playing fields, Green Lane, Malvern Wells)OS NGR: SO 777422 Area: 1.92ha Brown/Greenfield: GreenfieldFlood Zone Coverage: FZ3a: 5% FZ3b: 10% FZ2: 2% FZ1: 83%Exception Test required? Exception Test required? Yes, for Essential Infrastructure in FZ3b,for More Vulnerable development in 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 PoolBrook located to the west of the site, 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 needs to ensure that noincrease in flood risk occurs. Areas within Flood Zone 2 should be kept as openspace.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 114
Sources of Flood Risk:Primary flood risk to the site is fluvial, resulting from overtopping of from theunnamed tributaries of Pool Brook, to the north, west and south portions of the site.The north-west part of the site falls within Flood Zone 3b and the Blue Zone on thePolicy Maps. The B4209 Hanley Road and the Rothwell road, the main accessroads to the site are at risk from fluvial flooding.Further development and creation of impermeable surfaces may result in anincrease of surface water flood risk. The B4209 Hanley Road and the Rothwellroad, the main access roads to the site are at risk from surface water.2012s5947 S Worcestershire Level 2 SFRA Update FINAL Report v1.0.doc 115
