Flood Risk Assessment - Idmiston, Porton & Golmeldon

Flood Risk Assessment - Idmiston, Porton & Golmeldon


Acting on instructions from Idmiston Parish Council Southwest Environmental have undertaken a Parish Wide flood risk assessment, in advance of revisions being made to the parish plan.

The assessment is to ocver the 3 villages of Idmiston, Porton & Golmeldon and has a broad scope to cover the following sources of flood risk;

  • Fluvial - River Flooding from the River Bourne is  can affect some areas within the parish. Most developments are outside of Zone 3.
  • Pluvial - Surface Water flooding represents the highest risk within the parish. Run-off from side valleys to the main river valley create large volumes of run-off during.
  • Ground Water - Ground water is rather more occluded in nature than other types of flooding, it can affect.
  • Sewer -  Post intense rain fall events local sewer networks can become overwhelmed, this can be a result of blockages, poor maintenance or catchment transfer. 





A draft report has been produced with an aim to achieve a reduction in flood risk within the parish, this is to be achieved by a raft of measures which will be discussed with the Council Members, for inclusion within the final report.

The report was referenced in the submitted neighbourhood plan (page 32) for Idmiston Parish Council, the plan also contained some interesting photos supplied by Idmiston Residents.
