Flooding - Weymouth and Portland Borough Council

Flood protection information for residents in Weymouth and Portland Borough Council area.

In case of emergency during out of hours, please contact Weymouth and Portland Borough Council.

A limited stock of sandbags is held at the port main gate (Weymouth Ferry Terminal) for emergency use only.

We will endeavour to provide sandbags in an emergency to homes that are at imminent risk of internal flooding free of charge.

Remember, it is the property owner's responsibility to protect themselves from flooding in the first instance.

For more information please visit our page about disposing of sandbags.

Land drainage

Generally if the watercourse runs through or adjacent to your property/land you are a riparian owner. Riparian owners are responsible for the maintenance of the watercourse. If you wish to do any work in, above or near a watercourse you are likely to need consent from either the Environment Agency or Dorset County Council depending on the status of the watercourse.

The Environment Agency produces a helpful Living on the Edge leaflet (pdf, 143kb) (opens in a new window) explaining the rights and responsibilities of living next to a watercourse. Please note it is an offence to fill in or obstruct any form of watercourse.

For 'ordinary watercourses' within the district, Dorset County Council has powers to enforce the Land Drainage Act. For 'main rivers' the Environment Agency has the equivalent powers.

Advice for flood response - For the Chiswell area during severe flood warnings

Planning for floods

  • Use the generic Family Flood Plan to form the basis of a plan for your property
  • The area your property is in would be subject to fast flowing water in a flood event
  • There is also the possibility of wind blown spray and pebbles being thrown at the seaward side of your property. In a serious flood event cars and debris could be caused to float
  • If you don't have them already you should consider installing a frame for flood boards on any exterior doors. If you have existing slots please make sure you have the boards that fit them in an easily accessible place and a supply of waterproof sheeting and silicon sealant or expanding foam ready to use. If you have air bricks or other openings on the seaward side of the house you can protect these by keeping some suitably sized pieces of wood, ready to fix over the holes with silicon sealant in advance of a flood
  • It is also a good idea to think about installing removable shutters to your seaward facing window to prevent them from being broken by wind blown pebbles
  • Information on suppliers or DIY flood boards can be found in the Environment Agency Guide. "Preparing for a Flood"
  • Always keep any drainage channels running underneath your property clear

During a flood

  • You need to act quickly when a warning is issued as flooding could occur very rapidly
  • When you receive your warning phone call you should put your flood boards in place and close your shutters
  • Plan also to move your car and any large, loose objects away from the flood risk area at an early stage. Consider encouraging neighbours to do the same
  • Remember to also carry out the other actions you have prepared in your plan

When the siren sounds

The siren indicates that flooding will be severe with extreme risk to people and property. You should take yourself, family and pets to a room upstairs away from the seaward side of the building. Take your flood kit with you and stay there until you are told that it is safe to come downstairs. This could be a few hours later.
