Flooding & water

The human version (we wrote this, not the council)This section sets out the full wording and reasoning behind Policy DS.1 on environmental mitigation and compensation. Compensation is only supported where avoidance and mitigation are not achievable and where measures are deliverable, secured and managed long term. Off-site measures should align with local priorities such as the Warwickshire Local Nature Recovery Strategy. The policy extends the national mitigation hierarchy beyond biodiversity to other natural assets and ecosystem services, and it does not override statutory tests on heritage, flood risk or biodiversity.

The human version (we wrote this, not the council)This policy directs development to areas of lowest flood risk and requires that it does not increase flood risk elsewhere, allowing for climate change over the development's lifetime. Proposals must take a sequential approach to choosing and laying out sites, considering flooding from rivers, surface water, groundwater and sewers, informed by the Strategic Flood Risk Assessment. Flood management must be built in from the earliest design stages, and a site-specific Flood Risk Assessment is required, with hydraulic modelling where existing flood information is inadequate.

The human version (we wrote this, not the council)This section gives the full flood risk policy and its reasoning. On sites at risk, buildings must sit in the safest areas, safe access must be shown, and floor levels must be at least 600mm above the 1% annual probability flood level plus climate change allowance. All development needs a drainage strategy, an undeveloped buffer of at least 8 metres along watercourses, and space for water through green and blue infrastructure. South Warwickshire has a history of flooding from multiple sources, and climate change is expected to make floods more frequent and severe.

The human version (we wrote this, not the council)This policy aims to reduce flood risk from new development. South Warwickshire has a history of flooding from many sources, and climate change is expected to make floods more frequent and severe. Recent canal failures elsewhere have also highlighted a residual risk of flooding from canals, which should be considered in Flood Risk Assessments where relevant. Flood risk should be avoided where possible and managed effectively where development is needed, using nature-based solutions and green and blue infrastructure. Assessments should follow the latest strategic evidence and advice from the Lead Local Flood Authority.

The human version (we wrote this, not the council)This section sets out water efficiency rules for new development. South Warwickshire is classed as an area of serious water stress, so new homes must be designed to use no more than 100 litres of water per person per day. Homes with gardens must have a water butt of at least 200 litres. Non-residential buildings over 1,000 square metres must meet the BREEAM Excellent water standard and assess options for reusing rainwater or greywater. Extensions, changes of use and farm irrigation reservoirs are also covered.

The human version (we wrote this, not the council)This policy requires developers to show that enough water supply and sewerage capacity exists, or will be provided, before new development is occupied. Applicants must consult the water company, keep surface water and foul drainage separate, and avoid harming water quality in rivers or groundwater. Major schemes need an Outline Foul Drainage Strategy showing connections, upgrades and phasing. Development near sewage works must assess odour, noise and similar impacts. New or upgraded water infrastructure will be supported where its impacts are acceptable.

The human version (we wrote this, not the council)This section explains how the water and wastewater policy will work in practice. Severn Trent Water is the water and sewerage company for South Warwickshire, and developers are urged to engage with it early because a right to connect does not guarantee that capacity exists. Any needed upgrades will be secured through planning conditions or legal agreements. Connecting surface water to foul sewers is unacceptable unless approved and no other viable option exists. A possible law change would remove the automatic right to connect surface water to public sewers.

The human version (we wrote this, not the council)This policy requires high-quality sustainable drainage systems, known as SuDS, across whole development sites to manage rainwater and cut flood risk. A drainage strategy must show that runoff is handled close to where it falls, that properties would not flood in a storm with a 1% chance of occurring in any year, allowing for climate change, and that flood risk is not increased on site or elsewhere. Blue-green corridors should be kept and improved, and brownfield sites should disconnect from combined sewers wherever feasible.

The human version (we wrote this, not the council)This section adds detail on how sustainable drainage systems should be designed. SuDS must be planned as an integral part of the site layout, favouring above-ground and dispersed features rather than reliance on one large storage feature. They should deliver several benefits at once: reducing flood risk, cleaning water through a four-stage treatment train, boosting wildlife, providing attractive amenity space and helping to cool urban areas. Drainage features should also become part of the wider ecological network.

The human version (we wrote this, not the council)This section explains the green and blue infrastructure policy and sets measurable standards. Major developments must provide a green and blue infrastructure strategy. Commercial schemes must achieve an Urban Greening Factor score of at least 0.3 and residential schemes at least 0.4. Tree canopy must cover at least 14% of commercial sites and 20% of residential sites, or improve on existing cover if that is greater. These networks support wildlife, manage flood risk, store carbon and provide accessible space for recreation.

The human version (we wrote this, not the council)This section sets out the full requirements for trees, hedges and woodlands. Development must keep buffer zones around ancient woodland and veteran trees, design retained trees into streets, open spaces and drainage from the start, and deliver a measurable increase in tree canopy cover. All planting must use native, climate-resilient species and have maintenance plans, including replacing failed planting. The justification notes tree cover is uneven across the area and points to recognised standards such as BS 5837 for tree protection and the UK Forestry Standard.

The human version (we wrote this, not the council)This section sets out the full waterways policy. Development affecting waterways must not harm water quality, heritage, landscape, biodiversity or the usability of towpaths, and should improve access and active travel routes. On navigable waterways, moorings and marinas are supported where they do not damage the waterway or its surroundings, with canal regeneration encouraged, notably around the Grand Union Canal Conservation Area. Culverts are permitted for access only. Major schemes should consider new moorings for boat dwellers and strategic opportunities such as the Tach Brook re-naturalisation and a River Avon Linear Park.

The human version (we wrote this, not the council)This section covers proposal BIT.2 at Red House Farm, south-west of Bishop's Tachbrook. The 160-hectare site provides around 121 hectares of strategic employment land, totalling 3,750,000 sq ft of floorspace mainly for logistics and industry. The developer will fund a new M40 junction to replace junctions 13 and 14, plus a dual carriageway link road to Warwick and Leamington. The scheme also includes a Park and Ride, a central mixed-use hub, 39 hectares of green and blue infrastructure, and a travelling showpersons yard of at least 6 plots. Delivery runs from 2027 to 2034/35.

The human version (we wrote this, not the council)This section describes proposal HEN.1 at Henley-in-Arden, a 125-hectare masterplanned development of at least 2,084 homes, largely on the golf club land, delivered from 2029/30 to 2044/45. It includes 3.3 hectares of employment land, a two-form entry primary school, expansion of the secondary school with a new sixth form, 9 Gypsy and Traveller pitches, and a new country park at Beaudesert Mount. A link road from the A3400 to the A4189, including a new rail bridge, will let through traffic bypass the town centre. The site will be released from the Green Belt.

The human version (we wrote this, not the council)This section covers proposal LEA.1 at Blackdown, north of Leamington Spa. Some 72 hectares will be released from the Green Belt for at least 1,043 homes on about 37 hectares, plus roughly 35 hectares of public open space, delivered between 2031/32 and 2041/42. The scheme includes a two-form entry primary school, a community hub and safeguarded land for expanding North Leamington School. Land may also be needed for a future Park and Ride, and the site must contribute to the Kenilworth to Leamington cycle route.

The human version (we wrote this, not the council)This section describes proposal COV.2 at Coventry Airport, a 117-hectare site released from the Green Belt for advanced manufacturing and engineering, reflecting its place in the West Midlands Investment Zone. It particularly targets battery manufacturing for electric vehicles. At least 60% of floorspace must be industrial or research uses, warehousing cannot exceed 40%, and very large warehouse units over 32,500 sq m are not supported unless tied to manufacturing. Applications must include a marketing strategy showing how investment in these sectors will be attracted.

The human version (we wrote this, not the council)This section covers proposal SOU.1, land east of Southam delivering at least 3,122 homes across 201 hectares between 2028 and 2045. It includes 2.8 hectares of employment land, 13 Gypsy and Traveller pitches, three primary schools, a new secondary school plus a one-form expansion of Southam College, and two local centres. Densities of at least 40 homes per hectare apply. Bus services must improve, including a half-hourly service to Leamington, and development must keep a strong sense of separation between Southam and Napton on the Hill.

The human version (we wrote this, not the council)This section describes proposal WAR.1, 51 hectares west of Warwick Racecourse delivering at least 850 homes between 2031/32 and 2040/41. The scheme includes a new country park with play areas, sport and flood management, plus a new off-road walking and cycling route across the A46 to Warwick Parkway station. A spine road will link Hampton Road and Old Budbrooke Road. Built development must avoid the flood-prone eastern part of the site and protect the character of the Warwick Conservation Area, with the racecourse running flat retained or relocated.

The human version (we wrote this, not the council)This section provides the plan's glossary, defining the planning terms and acronyms used throughout the document, from accessibility and affordable housing to water neutrality. It explains concepts such as biodiversity net gain, brownfield land, the Community Infrastructure Levy, Green Belt and Grey Belt, flood zones, Section 106 contributions, sustainable drainage systems and the standard method for calculating housing need. It is a reference tool to help readers understand the technical language in the rest of the plan.
