Surface Water Management Plan - Hampshire County Council

It is recommended that the information in this SWMP is publicised so as toraise awareness of the information available to assist the public in identifyingthe potential level of flood risk in their area and to assist in the provision ofproperty level protection information.8. Evaluation of Options & ConsiderationsIn order to determine the suitability of mitigation options for these locations apreliminary assessment of each identified flood location will be required inorder to determine the cause of flooding, factors contributing to flooding andwhether any works can be undertaken in order to remove or reduce the risk offlooding.At this phase of evaluation options should not be constrained by availability offunding or delivery mechanisms and should identify all feasible measuresavailable for managing surface water flood risk. Consideration should also begiven to other sources of flooding and their interaction with surface waterflooding and opportunities for measures that deliver multiple benefits.In some cases it may not be possible or cost-effective to undertake mitigationworks at present but the consideration of other investment projects such asthose of the water companies, developers or other partners may make themitigation of surface water flood risk more viable.In these instances, the SWMP should identify a suitable strategy to ensure theinvestment reduces surface water flood risk.It is recommended that the borough council takes into account areas identifiedas having the potential for surface water flooding as identified within thisSurface Water Management Plan and identifies the need for flood riskmitigation infrastructure when setting its Community Infrastructure Levy.It is vital that key partners and stakeholders, including the local community,are engaged in this process. This can help determine the level of publicinterest and support for risk management as well as the appetite for localfund-raising to assist in the delivery of flood mitigation and alleviationmeasures.It is recommended that short-listing of these measures is undertaken using atwo stage process as defined in the Defra Technical Guidance. Stage 1 of thisprocess requires further site inspections to consider the technical feasibilityand relevance of each measure at each of the detailed sites. This processadopts the following scoring system:3 - Feasible with significant benefit;2 - Feasible with some benefit;1 - Feasible but marginal benefit; and0 - Not Feasible or Not Relevant.28
