An evaluation of changes in storm water discharge as a consequence of block paving in heavily suburbanised areas: A case study in Tewkesbury

Historically prone to flooding, the Abbey town of Tewkesbury has, nevertheless, been prone to more surface water flooding and damage in recent years than had hitherto been the case. Focusing on those suburbs of the town most removed from the River Severn, this dissertation measures storm water discharge flow rates off properties that have retained front gardens (of a grass and soil basis) compared to those that are predominantly comprised of block paving and or driveways. Thereafter presenting the findings, this dissertation seeks to suggest that the changes wrought to surface water and storm water discharge patterns by such changes in ‘gardening’ need to be examined with a view to legislation being passed relating to maximum permitted surface areas that can be covered in concrete/block paving to the front, side and rear elevations of houses in suburban areas.
