context_page_description: The 2004 Boscastle flood occurred on Monday, 16 August 2004 in the two villages of Boscastle and Crackington Haven in Cornwall, England, United Kingdom. The villages suffered extensive damage after flash floods caused by an exceptional amount of rain that fell over eight hours that afternoon. The flood in Boscastle was filmed and extensively reported but the floods in Crackington Haven and Rocky Valley were not mentioned beyond the local news. The floods were the worst in local memory. A study commissioned by the Environment Agency from hydraulics consulting firm HR Wallingford concluded that it was among the most extreme ever experienced in Britain. The peak flow was about 140 m³/s, between 5:00 pm and 6:00 pm BST. The annual chance of this flood in any one year is about 1 in 400. The probability each year of the heaviest three-hour rainfall is about 1 in 1300. At midday on 16 August 2004, heavy thundery showers had developed across the South West due to a weak disturbance to the northeast of the United Kingdom.
  The last time Boscastle had suffered notable flooding was in 1996 as a result of Hurricane Lili, but floods are recorded in 1847, 1957, on 3 June 1958 and in 1963.
context_section_description: Most work took place in the winter season (October–May), during the off-season. The carpark was reduced to half capacity (120 spaces) in winter, for works to take place, and then back to 240 spaces in summer.
