Catchment Partnerships Upper Piddle Valley Project — Slowing the flow using Natural Flood Management techniques © Lorraine© Igar What is Natural Flood Management? Natural Flood Management (NFM) involves working with nature to ‘slow the flow’ of water across a landscape. There are a variety of techniques that can be used, including; cross drains, earth bunds, leaky ponds, cover crops, hedges, trees, reducing compaction and grass buffers. These techniques all work together to hold flood water upstream and allow water to release slowly back into the river, helping to reduce the frequency and magnitude of future floods in the Piddle Valley. It also helps to deliver a range of other benefits to the local environment, including improvements to water quality, biodiversity and climate change mitigation. NFM projects can compliment the flood projects delivered by other organisations. For more information on successful projects using these methods please visit: www.stroud.gov.uk/ environment/flooding-and-drainage/stroud-rural-sustainable-drainage-rsuds-project The Piddle Valley. Surface water and groundwater flooding A combination of factors makes the Piddle Valley susceptible to flooding but also a good opportunity to use a sustainable approach to reducing this risk. The steep slopes fall sharply into a flat river valley. The river Piddle and the Plush Brook are fed by both groundwater and surface water. The historic modifications to the watercourses means that they are straighter, unconnected to the floodplain and so respond quickly to heavy rainfall. The combination of free draining soils of the upper valley and impeded drainage on the clays, steep slopes, climate change and the position of the villages contribute to flood events like that in February 2016. © Environment Agency copyright and / or database rights 2017.

Chalk catchments, like the Piddle Valley in Dorset are Land management practices can help to ‘slow the flow’ susceptible to groundwater flooding during wet winters or and store water; rich organic soils can hold four times following extreme rainfall events. In summer, rainfall is their weight in water. Healthy soils also retain nutrients absorbed by vegetation but in winter it recharges the aquifer and sediments are less likely to run-off fields.

Working together in the Poole Harbour catchment will ensure that projects are co-ordinated to deliver the greatest number of benefits in the most cost effective way. Our projects aim to reduce nutrient pollution and help rivers to function more naturally for flood risk management, fish and other wildlife benefits. Some examples of projects that are already working to deliver improvements to the quality of the water environment and contributing to reducing flood risk are detailed below.

  • Piddle Valley Conservation Area Review

    Piddle Valley Conservation Area Review

    Item 14 Council Meeting – 16 January 2018 Piddle Valley Conservation Area review 1. Purpose of report The purpose of this report is to seek the Council’s approval to adopt the draft appraisal and boundary proposal prepared for Piddle Valley Conservation Area. 2. Key issues 2.1 The Council designates and reviews conservation areas in fulfilment of statutory duties under Section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990. Purbeck District has twenty five Conservation Areas, twenty-two of which have been appraised and reviewed since their designation, twenty-one of these since 2008. 2.2 A conservation area is a historic built environment designation. The designation promotes the preservation and enhancement of groups of buildings and structures which hold special historic or architectural interest, together with associated spaces and trees. This is primarily achieved through the sensitive management of change within the planning process. 2.3 Paragraph 127 of the National Planning Policy Framework (NPPF) highlights the importance of ensuring that conservation area designations are justified. This is the key objective of the boundary review, and ensures fairness in the application of controls, and soundness in case of appeal against planning decisions. 2.4 The Council has a statutory duty to consider the impact of planning proposals upon conservation areas. This is reflected in paragraph 129 of the NPPF, which requires local planning authorities to assess the significance of heritage assets as part of the development management process. Assessment of significance is a key objective of conservation area character appraisals, and therefore provides the Council with an important part of the required evidence base in decision making.

    The Wareham Two Rivers Walks

    THE WAREHAM Two Rivers Walks TWO RIVERS WALKS The Two Rivers Walks journey through beautiful ecologically-rich areas as they wind alongside the River Frome and the River Piddle. These two rivers flow through Wareham into Poole harbour, one of the largest natural Wareham to Swineham point harbours in the world, and support a wide variety of stunning flora and fauna. Along this walk experience: - Incredible Biodiversity The two rivers walks travel through designated Sites of Special Scientific Interest (SSSI). The combination of soil type, wet areas, tidal flooding and land management has supported the rich ecology and biodiversity for which the area is renowned. This area supports 40,000 birds in the winter, and a wonderful variety of birds can be seen throughout the year such as lapwings, redshanks and kingfishers. It is not uncommon to see otters along this route and hear River Piddle fisheries the ‘plop’ of a shy water vole dive into the water before being seen. The rivers also support a variety of fish such as Ragged Robin trout and salmon which spend much of their life at sea but return to healthy rivers to breed. - Archaeological History The stunning landscape that can be viewed along the walk has been shaped by human activity throughout the ages. Excavations have shown that the area has been used by humans for thousands of years, with relics being found that show there were once Bronze Age settlements here. River Frome reed bed The rich natural resources that were in this area, such as clay, stone and chalk were what would have once attracted settlers to Wareham.

  • Piddle Valley Neighbourhood Plan Final Pre-Sumission Consultation Draft

    Piddle Valley Neighbourhood Plan Final Pre-Sumission Consultation Draft

    Piddle Valley Neighbourhood Plan 2016 to 2031 Draft for pre-submission consultation - September 2015 Produced by Piddle Valley Parish Council with the help of local residents Piddle Valley Neighbourhood Plan – 2016 to 2031 How this Plan came about Back in 2012, the idea of a Neighbourhood Plan for the Piddle Valley was discussed at the Parish Council meetings. A small working group was formed. Having done some research and looked at other examples, the group wanted to be sure that there was enough support for a Neighbourhood Plan, as it was clear that producing a plan would take a lot of community time and effort. So the group put articles in the Piddle Valley News and Views to try to explain what a Neighbourhood Plan was, and what it could achieve, and organised presentations at the school in October that year. They gave local residents the chance to vote whether or not they wanted a Neighbourhood Plan. They explained that - If nothing is done, then future planning decisions that affect the Valley will be taken by the District Council as they see fit. If the Valley has its own Neighbourhood Plan, which sets out our wishes for things we both do and do not wish to see occur, then the District Council have to take those views into account in reaching their decision. The Plan will take a lot of time and work to prepare, including further consultations, and must eventually be approved by a referendum of the Valley residents. It is important therefore for the Parish Council to know that there is support in principle for the work involved.

  • River Piddle Project

    River Piddle Project

    Armchair Adventurers Extracts from the River Piddle project The River Piddle [also known as the Trent] is relatively small [30km], flowing from chalk lowland calcareous [sedimentary rock with a high proportion of calcium carbonate] downlands in central Dorset to the sea at Wareham where the river is tidal and prone to flooding. The bedrock in the upper Piddle Valley is alluvium [clay silt and sand] changing to clay and flints as it nears Wareham and Poole Harbour, the second largest natural harbour in the world. British Petroleum seismic surveys and oil well sinking data, taken during the development of the Wytch Farm Oilfield, took the geological knowledge of the area back 260 million years to the Variscan orogeny. A readable description of this is available at https://www.nora.nerc.ac.uk . The glacial and interglacial cycles that followed, especially the most severe one 450,000 years ago, released large quantities of meltwater into the Solent [the stretch of water that now separates the Isle of Wight from the mainland]. Over time the Solent divided into the river system we see in the area today, including the River Piddle. The river has been extensively modified. Geography The landscape is of dry valleys and winterbournes [a river or stream that is dry through the summer months]. The River Piddle rises from four large springs at Alton Pancras, and is contained in a brick channel. From the 17th century watermeadows were created to flood grassland to force early growth of grass for grazing which is evidenced by the many channels to be found and a lot of boggy land.

The slopes and crests are mostly comprised of shallow well-drained calcareous silty soils over chalk, whilst the valley bottoms are made up of deep calcareous and non-calcareous fine silty soils. Due to its geology and topography, the Piddle Valley is prone to high water tables during prolonged wet periods.

June 2012 Introduction I am pleased to introduce our summary of the Frome and Piddle Catchment Flood Management Plan (CFMP). This CFMP gives an overview of the flood risk in the Frome and Piddle catchment and sets out our preferred plan for sustainable flood risk management over the next 50 to 100 years. The Frome and Piddle CFMP is one of 77 CFMPs for The Frome and Piddle catchment has a history of flood England and Wales. Through the CFMPs, we have risk. Over the last 40 years engineering schemes have assessed inland flood risk across all of England and been implemented to reduce flood risk in the Wales for the first time. The CFMP considers all types of catchment. At present 1,160 properties are at risk in inland flooding, from rivers, ground water, surface the catchment in a 1% event (taking into account flood water and tidal flooding, but not flooding directly from defences).
