Planning & Transport StrategyWigan Metropolitan Borough CouncilCivic BuildingsNew Market StreetWIGANWN1 1RPFor the attention of Damian Garner, Assistant EngineerOur Ref: RW\2009s0578-S-L007-1.doc10 December 2010Dear Sirs,Wigan Borough Level 2 SFRAFirstly thank you for forwarding our reply to the Environment Agency (EA) comments onthe Wigan Borough Council SFRA to Helen Telfer. We have carefully reviewed the EA’sadditional comments (retained in italics) and include our response below.Above all the SFRA is a strategic review and having read the EA’s response we considerthat they are asking for information that is beyond the practical scope of the study. Wefeel that if the EA’s comments are accepted by the Council then the SFRA risksbecoming a highly prescriptive document that may stifle justifiable development andinnovation in design.The variation in EA responses to SFRAs on a regional basis is rather stark and we areparticularly concerned that the EA’s response, in this instance, appears to have driftedfrom the fundamental purpose of an SFRA to instead focus on issues that will invariablyhave to be assessed in detail as part of an FRA. The SFRA should not try to rigidlyprescribe design and development requirements as developers and architects must beable to design proposals that are appropriate and functional.In addition we have worked closely with you to identify the key risks and issues fordevelopment. We can only advise the Council and ensure that our comments in theSFRA reflect your aspirations as well as the likely constraints to development.Above all the SFRA clearly specifies that:1 development must be appropriate; and2 flood risk associated with development must be fully mitigated.EA comment:Level 2 SFRA ReportDevelopment Behind Defences and Current Condition of Flood DefencesJBA have confirmed that a condition assessment of flood defence infrastructure has notbeen undertaken. We would refer the Council to paragraph 2.7 (a) of the SFRA briefwhich states that the SFRA should contain the following as a minimum:“A schedule of the current condition of flood defence infrastructure, both formal andinformal, cross-referenced to specified policies in the Environment Agency’s River
