Title: Protecting Porthleven
Author: Environment Agency South West Region
Document Type: Monograph
The fishing village of Porthleven lies in south west Cornwall, between Helston and Penzance. The Porthleven Stream runs through the centre of this popular Cornish fishing village and is responsible for a long history of flooding. The flood defence scheme for Porthleven was drawn up mainly in response to the flood, which happened in 1993, when 14 residential and commercial properties were inundated with water. The rainfall gauge at Culdrose, Cornwall, recorded that 126 millimetres (5 inches) of rain fell between midnight 8 June 1993 and 10.00am the following day. The scheme works by allowing the existing culvert to fill to its capacity, and then direct excess floodwater, via an overflow, through a new culvert into the inner harbour alongside the slipway. Gala Parc will still flood occasionally, although not as deep as before, and new banks, ramps and walls have been built to keep floodwater out of homes and businesses.
