Crynodeb o'r Gynrychiolaeth:

With the exception of FW1 (f) we are broadly supportive of the Councils approach to flooding and water. The paper highlights the importance of resilience and this is a key issue for farmers and growers in the district. Large new developments in urban areas do have the potential to cause downstream impacts, even when new SUDs techniques are employed. It is important to recognise that farmers have to deal with these impacts as they are responsible for maintaining many of the area's watercourses and drainage infrastructure. Waterlogging and flooding has the potential to directly impact upon the productivity of agricultural land so it is important to value and maintain our existing drainage infrastructure.

Suggest that title of this policy is changed as it implies that development in areas of risk of flooding is appropriate , which is contrary to NPPF in which the aim of the Sequential Tests is to steer new development to areas with the lowest probability of flooding. We recommend that an alternative policy title such as „Reducing Flood Risk‟ is used instead. Where there are no reasonable available sites in Flood Zone 1, the Sequential Test should be applied; taking into account the flood risk vulnerability of land use and consider reasonably available sites in Flood Zone 2, applying the Exception Test if required. Only where there are no reasonable available sites in Flood Zones 1 and 2 should the suitability of sites in Flood Zone 3 be considered, taking into account the flood risk vulnerability of land uses and applying the Exception Test if required. As soon as the need for the Exception test is established, a level 2 SFRA should be undertaken by a suitable qualified technical expert or engineer. We have the following comments on the criteria outlined for this policy in relation to each bullet point within the policy. a) The SFRA level 1 Flood Zone maps are based on our Flood Map (fluvial risk) and the Areas Susceptible to Surface Water Flooding, now known as the Updated Flood Map for Surface Water (surface water risk). Unless there are plans to continually update the SFRA mapping, we suggest that our online Flood Map (now known as "Flood Map for Planning") available on the .GOV.UK website is referred to as this is updated on a quarterly basis and should provide the most up to date information.
b) this is essentially the Sequential test, and we would consider this criteria is re-worded to:
'the Sequential test is applied on the site so that the most vulnerable development is located in areas of lowest flood risk'.
c ) We recommend that the term "flood defence" in this criterion is replaced with the following wording
'development is appropriately flood resistance and resilience'
Because the term flood defence suggests formal flood walls etc which will prevent flooding in all circumstances, however even development behind flood defence structures can experience flooding through breach or overtopping. It is far more practicable to direct new development to flood zone 1 rather than in an area benefiting from existing flood defences. This should not be used to justify development in inappropriate locations.
e) Request clarification as to how the term "regular flooding" defined, we feel that this should either be removed from the policy, or the wording changed to indicate a likely return period, paying due regard to the NPPF which has a presumption against all development within the functional floodplain unless it can be described as water compatible.
g) Suggest this is re-worded to the following text:
'the development must be 'safe' over its lifetime, taking into account the effects of climate change. Safe pedestrian and emergency vehicle access routes above the 1:100 year plus climate change flood level must be available. Evacuation plans must be prepared for all new developments in flood risk areas'. Suggest that the paragraph "land that is required for current and future flood management will be safeguarded from development" is added as a continuation of the points (i) rather than a separate paragraph. We recommend that the paragraph "Where development is supported as an exception to this policy..." is removed, as there shouldn‟t be any exceptions to this policy and all criteria must be complied with. This wording is repeated in paragraph 5.130 and should be removed.
This is contrary to the National Planning Policy Framework, and the Environment Agency must object in principal to inappropriate development within the floodplain.
We would object to this section policy at a formal review of this plan, and it‟s inclusion could render the policy as unsound. We recommend the addition of the following criteria to Policy FW1 as supported by the level 1 SFRA: 'j) the functional floodplain is protected from all built development.
k) space should specifically be set aside for Sustainable Drainage System (SuDS) and used to inform the overall site layout.
l) development proposals must provide a minimum 8m wide development buffer strip from watercourses (culverted or otherwise).
m) every opportunity should be taken to de-culvert and re-naturalisation of watercourses. Culverting of existing open watercourses will not be permitted.
n) opportunities should be sought to reduce the overall level of flood risk in the area and beyond through the layout and form of the development, and the appropriate application of SuDS.
o)for residential development, finished floor levels are set a minimum of 600mm above the 1% (1 in 100 year) plus climate change flood level.
p) developers will be required to contribute towards the cost of planned flood risk management schemes that will benefit the site.
q) opportunities should be sought to make space for water within the development to accommodate climate change.
r) Development proposals will demonstrate that will not cause deterioration of the waterbodies WFD status and contribute to meeting good status.
s) Carry out a WFD Assessment to demonstrate how the waterbody will not deteriorate in status and will be enhanced
t) No detrimental impact on priority habitat or designated sites of nature conservation.' With regard to the FRA requirements, we suggest that point (a) is re-worded as
'within Flood Zone 2 or 3 or proposals of 1 hectare or greater in Flood zone 1, as defined on the Environment Agency's Flood Map for Planning'.
The mapping in Warwick District Council‟s SFRA level 1 is based on our Flood Map. The SFRA report states that it is a "living" document and should be reviewed on a regular basis. Our Flood Map for Planning is updated on a quarterly basis to incorporate improved river models etc and this should be reflected in the SFRA document.
However, if there are no plans to update the SFRA maps on a quarterly basis in line with our Flood Map updates, then we recommend that our Flood Map is considered the best available information or until such time as a level 2 SFRA is produced. Recommend that bullet points are used in this section so as to avoid confusion with the numbering system used in the criteria part of the policy. Paragraph 5.131 Our "Flood Map for Planning" replaced the indicative flood zone maps and should be referred to in this paragraph. FW2 Sustainable Urban Drainage We recommend that the title of this policy is re-worded to 'Sustainable Drainage' as the sustainable drainage applies to both greenfield and brownfield sites.
In the first paragraph "Sustainable Urban Drainage Systems (SUDS)" should be replaced with „Sustainable Drainage Systems (SuDS)‟ as they are now known.
The retrofitting of SuDS onto existing drainage systems should be a requirement for developments where it is not possible to install an entirely new system. Recommend that the following text is added to point c):
'ecological networks and informal recreation'
Suggest that the middle paragraph of this policy is re-worded as follows to make it clearer on the surface water hierarchy and that surface water discharge should be limited to greenfield runoff rate for all points of discharge:
„Surface water runoff should be managed as close to its source as possible in line with the following drainage hierarchy: i. Discharge into the ground (infiltration) unless it is demonstrated by infiltration tests and groundwater levels that infiltration is not possible. ii. Discharge to a surface water body. iii. Discharge to a surface water sewer, highway drain or another drainage system. iv. Discharge to a combined sewer. Above ground storage, such as balancing ponds, should be considered in preference to below ground attenuation, due to the water quality and biodiversity benefits they offer. For all sites, surface water discharge rate should be limited to the site-specific greenfield runoff rate for all return periods up to the 1% (1 in 100 year) plus climate change event' We recommend that the paragraph which includes the text "In exceptional circumstances, where a sustainable drainage system....c) contributions will be made to off-site SuDS schemes" is removed.
This wording provides an unnecessary get out clause and could result in the delivery of unsustainable development, sustainable drainage systems take many different forms and there is no reason why a SuDS solution cannot be designed for every site.
We welcome the policy requirement for developers undertake groundwater risk assessment to ensure that groundwater quality is protected a result of development proposals. Subsequently any proposal involving infiltration SuDS schemes should be accompanied by contaminated land investigations to endure that site condition is appropriate.
For sites that are identified as significantly contaminated EA would require input into any SuDS schemes proposed for new development to determine the most appropriate schemes. This would be to safeguard groundwater quality.
