Canvey’s Flood Apathy will bite us in the Wallets!

Canvey Island is facing plans from developers that may have a direct impact on the value of their homes!


New large developments on Green Belt and Green Field’s are being proposed that intend to raise land levels in the region of 1 1/2 metres above neighbouring land levels  so as to mitigate Flood Risk.

The effect this will have on existing property is two-fold. One, it may well increase flood risk to neighbouring properties and secondly will undoubtably have an negative effect on the neighbouring property prices.

Visitors will be unable to not notice new homes and business developments built on this raised land. Through this it will not take them long to realise that Canvey is liable to flood and in the circumstances it would be unwise to purchase properties at normal ground level. Consequently house prices could well fall.

This would actually cause the deprivation, that CPBC argue new development is required to prevent!

And yet currently our local Councils have no Policy in place to deal with the matter.

Instead it is left to the Developers to come to an agreement with the Environment Agency that Flood Risk issues will not be too badly affected.

Interesting how this can be achieved whilst absolutely nobody currently has any idea of the capability of Canvey’s drainage system to cope with a rain storm.

A breach of the sea defence would overwhelm the drainage system and these land raised areas would likely cause greater depths of flood than would previously be the case.

Why local representatives have not taken a lead on this is questionable. It could be argued that we must have confidence in the Environment Agency, however they only consider the actual proposal and any affect on land directly adjacent. They also expect our local authority to give the ultimate decision on any development proposal’s suitability.

The  fact that existing property prices would likely be affected by a land raised development, would not be considered a Planning Matter.

Why are Alarm Bells not Ringing ?

    You are quite right to highlight the issues of land raising being the selected method being pursued by developers of a way of overcoming their particular development being deluged by flood water, be it surface or failure of our sea defence. We on Canvey Island live in a bowl, water having the natural tendency to level out will consequently have less surface area on which to do so if the practice of land raising is allowed to perpetuate. It is worth remembering that a cubic metre of land fill equates to a displacement of 1000ltrs.of water. That water needs to go some where, given recent events some of Canvey’s properties may flood yet again. I do hope that CPBC have enough funds to pay the compensation costs should the planners get this wrong yet again.

    • Thanks for the input Steve, and to put it in old money that is more easily visualised 1 cubic metre = 219.97 gallons!
      The intention to develop the South of Roscommon Way involves land raising with an amount of soil matter to the equivalent of almost 23 Millon Gallons worth of cubic space.
      Should the unthinkable happen, It would have to go somewhere!
      And yet nowhere has the implications been discussed!!

    Editor:- Would you kindly indulge me in an attempt to state the obvious.

    “Archimedes’ principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes’ principle is a law of physics fundamental to fluid mechanics.”

    . Perhaps this would help the Planning Committee when deliberating on the aspect of land raising to prevent flooding, I am sure that most of them use baths at home and know when the level of water it holds is sufficient to prevent overspill, thus avoiding flooding their bathrooms.
