Angarrack

Flood Plan

The purpose of this plan is principally to alleviate the effects of flooding from the Angarrack river and surface water run-off, for residents of 3 properties in Hatch’s Hill and several properties in Riverside. Copies of this flood plan will be made available to all affected residents and holiday homes for the benefit of guests.

Angarrack Flood Risk Assessment

Hazard Likelihood Severity Consequence
Flooding from Angarrack river via Northern tributary Flooding from heavy, intense, prolonged rain During periods of very high Rainfall, flash storms can be severe Properties and adjacent roads may be affected
    
Hazard Likelihood Severity Consequence
Flooding from surface water run-off Dependent on amount and height of river level Could be severe in Hatch’s Hill area Properties and adjacent roads may be affected
    
Hazard Likelihood Severity Consequence
Flooding from culvert overflow Flooding in heavy, continuous rain, if blockage occurs During periods of prolonged heavy rain, could be severe Properties and adjacent roads may be affected
The main risks are flooding from Angarrack River via its Northern tributary and from surface water run-off when the drains cannot cope. This flood plan deals with these threats. Some surface water drains discharge into the river, the level of which can rise quickly during long periods of heavy rainfall, preventing the surface water dispersing and putting several properties at risk.

 

Flood Management Procedures

  • Debris catcher installed on upstream side of culvert.
  • CCTV installed on upstream side of culvert and monitored by the EA.
  • The penstock gate on the culvert is normally closed to prevent flows into the river.
  • The Environment Agency currently keeps the culvert clear and strims the river bank twice a
    year
  • Volunteer Flood Wardens will monitor the river and culvert and report issues to the EA.
  • Riparian owners have been advised of their responsibility to keep the river clear.
  • Road drains cleared annually and also when necessary.
  • Volunteer Flood Wardens will monitor the drains and report any blockages to Highways.
  • Additional drains installed on Hatch’s Hill.
  • Flood Proof doors fitted to nos. 2 and 3 Hatch’s Hill

Desirable additional measures, not yet implemented:

  • Extend the drain pipe in the river, by the road bridge, to increase capacity for surface water to drain away.
  • Restore the ’throttle’ device on the Northern tributary, to slow down excessive flows.
  • Clear excess silt in the river, by and under the
    road bridge, to increase capacity.

Equipment

Sandbags and a pump are available, particularly
for nos. 2 and 3 Hatch’s Hill.

During periods of expected heavy or prolonged rainfall, the following procedures will be followed.

Monitoring Process

Residents can sign up for an alert from the Floodline Warnings Direct service provided by the EA www.environment-agency.gov.uk/flood

  • A 10 Point Household Flood Action Plan has been provided to all households at risk.
  • Copies of this Flood Plan will be supplied to all households at risk.
  • Flood Wardens will monitor the state of the river and surface water and cascade warnings as necessary.
