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.

Flood Risk Assessment Wiltshire

Acting on instruction from a local authority Southwest Environmental Limited are to carry out a flood risk assessment for a proposed car car in Seaton, Devon.

The site is within a very complicated area with regards to flooding with recording instances of sewer and river (fluvial) flooding. Owing to the site’s proximity to the sea the action of waves is also important, having to be assessed relevant to the quality of flood defences in the area.

As well as up to date flood data the data ordered also contained various historic data as per above. This is not the not, and is handy as it includes information on the location of sewer flooding.

Flood Risk

SWEL were engaged by a firm of architects in Wandsworth, London to undertake a flood risk assessment for a change of use planning application.

The report was completed in under 5 working days, and issued via email. Recommendation were that checks should be made to confirm estimate existing floor levels and if they were above a certain level, then permission should be granted.

Of higher than usual concern in the area was sewer flooding, which may have been a result as a result of catchment transfer on a local level.

Flood Risk Assessment

Southwest Environmental Limited were approached by an individual looking to source a flood risk assessment for a property in Bewdley, Worcestershire.

The site appeared to be within flood zone 2, and cosisted of conversion of lost space in to a studio apartment. It was decided that owing to the low map resolution that it was likly the site was infact in flood zone 1, and this combined with the fact that the development was sited on the fiorst floor level, it was recommened as low risk.

Planning permission was sucessfully granted.
