Rickmansworth

The human version (we wrote this, not the council)This section explains the district's housing need and sets out the housing allocations policy. The plan runs from 2026 to 2041 and uses the Government's standard method, which gives a need of 832 homes a year and a target of 12,480 homes. After counting existing planning permissions and an allowance for windfall sites, 10,312 homes must come from allocated sites. The policy safeguards allocated sites for housing, expects development broadly in line with each site's stated capacity, and only allows earlier release of sites if the five-year housing land supply falls short.

The human version (we wrote this, not the council)This section describes the district and the issues the plan must tackle. Three Rivers covers about 88 square kilometres on the edge of London, with around 93,800 residents in 2021, projected to reach 98,919 by 2041 alongside a fast-growing over-65 population. It is among the least deprived areas in England, though pockets of deprivation exist, notably in South Oxhey. House prices averaged £594,000 in October 2025, making affordable housing a pressing need. Around 76% of the district is Green Belt, car dependency is high, and the council declared a climate emergency in 2019.

The human version (we wrote this, not the council)This section sets out the vision for Three Rivers as a desirable, prosperous district with sustainable settlements, a resilient economy and a high quality environment moving towards zero carbon. It lists the strategic objectives needed to deliver this, including a range of new homes with priority for rented affordable and family-sized housing, matching new jobs to new homes at a 1:1 ratio, making best use of previously developed land, and integrating infrastructure and sustainable transport. Other objectives cover heritage, climate change, biodiversity, open space, the district's rivers, good design, an ageing population, health and safeguarding the Green Belt.

The human version (we wrote this, not the council)This section sets out the site allocations for Chorleywood. Eight housing sites are allocated, references H18 to H26 (there is no H19), with a combined indicative capacity of around 217 homes. The largest are Land at Chorleywood Station (81 homes), North Hill Farm (57 homes) and Hill Farm, Stag Lane (40 homes); the smallest include garage sites and Chorleywood Library at five homes each. Site tables cover size, phasing, Green Belt or grey belt status and site-specific requirements such as access, heritage and flood mitigation.

The human version (we wrote this, not the council)This policy sets housing density expectations. New housing should normally be built at 50 dwellings per hectare within the developable area of a site, with higher densities expected in places well served by public transport, services and facilities. Lower densities may be acceptable in special cases, such as areas of historic or landscape value or specialist housing, but must be justified with supporting evidence. Density should generally be lower at the edges of a site and increase towards its centre.

The human version (we wrote this, not the council)This policy supports business growth by promoting a range of employment sites and premises across the district. Within designated Employment Areas shown on the policies map, extra industrial floorspace and intensified office and industrial uses are supported, and non-employment uses are only allowed where they would not harm amenity or the area's role. Outside these areas, losing employment land to other uses requires evidence including 12 months of unsuccessful marketing at a realistic price and no reasonable prospect of continued employment use. Creative industries and expansion of Leavesden Studios are supported.

The human version (we wrote this, not the council)This policy keeps Rickmansworth town centre and the district centres of South Oxhey, Chorleywood and Abbots Langley as the focus for shops, leisure and other town centre uses. Ground floors in primary shopping areas must keep active frontages that support the centre's vitality, while homes above shops are supported in principle. Local centres should meet day-to-day shopping needs. A retail impact assessment is only needed for schemes of more than 2,500 square metres of new retail floorspace outside the defined retail hierarchy, and shop fronts should suit the character of the area.

The human version (we wrote this, not the council)This policy requires qualifying development to deliver at least 10% measurable biodiversity net gain, meaning the site must be left better for nature than before, measured with the Government's statutory metric. Gains should be delivered on site first, then off site, with buying statutory credits a last resort, secured by monitoring plans lasting at least 30 years. Protection of wildlife sites is weighted by importance, from international down to local, and loss of irreplaceable habitats such as ancient woodland will normally be refused. New housing must provide on average at least one swift brick per dwelling for nesting birds.

The human version (we wrote this, not the council)This section sets out the site allocations for Rickmansworth. Six sites are allocated: four housing sites providing around 151 homes, including the Affinity Water Depot on Church Street (75 homes) and a depot at Stockers Farm Road (40 homes), plus two care home sites. Land on London Road is allocated for a 75-bedroom care home, counted as equivalent to 40 dwellings, and Meresworth for a 51-bed care home, equivalent to 27 dwellings. Site tables list size, phasing, Green Belt status and site-specific requirements.

The human version (we wrote this, not the council)This policy seeks a net gain in the quality and quantity of green and blue infrastructure, the network of green spaces, waterways and natural features across the district. Priorities include the chalk streams and corridors of the Rivers Chess, Colne and Gade, the Grand Union Canal, the Chilterns National Landscape, the Colne Valley Regional Park and Rickmansworth Aquadrome. New development must contribute to new and improved green space and better links between assets, with management and maintenance plans required. Public rights of way should be protected, ideally with 20 metre buffers, and development must not fragment the network.

The human version (we wrote this, not the council)This section introduces the environment chapter. The district takes its name from the Rivers Colne, Chess and Gade, which meet at Rickmansworth, and with the Grand Union Canal and many former quarry lakes the area has a complex flooding picture and a wide floodplain. Three Rivers faces flood risk from rivers, surface water, groundwater, sewers and reservoirs, and climate change is expected to increase that risk. At the same time the district lies in one of the driest parts of the UK, so development must be flood-safe and use water efficiently.

The human version (we wrote this, not the council)This policy manages flood risk and water use. Development in flood risk areas must pass national tests that steer building to the safest available land, and no new development is allowed in Flood Zone 3b, the functional floodplain. Floor levels in Flood Zones 2 and 3 must sit at least 300mm above predicted maximum flood levels, and major schemes need sustainable drainage limiting runoff to greenfield rates. Buildings must stay 10 metres from main rivers and 5 metres from other watercourses. As the district is seriously water stressed, new homes must use no more than 110 litres per person per day.

The human version (we wrote this, not the council)This policy governs the design and layout of residential development, requiring all schemes, including extensions, to meet the Design Criteria in Appendix 1. Development must not harm an area's character through tandem or backland building, poor access, excessive traffic or layouts out of keeping with plot sizes and street patterns. Tall buildings, meaning four or more storeys, over 12 metres, or substantially taller than neighbours, will be refused unless strict criteria are met. Converting a house into flats normally needs three or more bedrooms, and all homes must meet or exceed national internal space standards.

The human version (we wrote this, not the council)This policy protects the district's heritage, including 352 listed buildings, 22 Conservation Areas, Scheduled Monuments, registered parks and gardens, and locally important buildings. Applications affecting a designated heritage asset must include a Heritage Statement explaining the asset's significance and the proposal's impact. Substantial harm to or loss of listed buildings and other designated assets will be refused unless substantial public benefits outweigh the harm. In Conservation Areas, development must preserve or enhance character and appearance, with strict tests for demolition, and reuse of historic buildings to help tackle climate change is supported where significance is not harmed.

The human version (we wrote this, not the council)This section sets out the retail hierarchy and centre allocations. Rickmansworth Town Centre is the principal shopping and service centre, serving the whole district. South Oxhey, Abbots Langley and Chorleywood are district centres, while Croxley Green (Watford Road and New Road) and Mill End (Money Hill Parade) are local centres, with smaller parades serving day-to-day needs. New retail development will be directed to the primary shopping areas of the town and district centres first. The boundaries of these centres are set out in the allocations.

The human version (we wrote this, not the council)This policy requires new development to be located where sustainable travel is realistic. Schemes must support walking, cycling and public transport, with safe direct routes, secure cycle parking and good access for buses. Developments generating significant traffic must provide a Transport Assessment or Statement and a Travel Plan showing how impacts will be managed. Improvements will be delivered directly or funded through Section 106 agreements or the Community Infrastructure Levy, which are payments developers make towards infrastructure. Moving freight from road to rail or canal is supported in principle.

The human version (we wrote this, not the council)This section sets the district's parking standards for cars, disabled parking, cycles, electric vehicles and powered two-wheelers. Standards vary by use, for example one space for a one-bedroom home and 2.5 spaces for homes with four or more bedrooms, and can be adjusted with robust evidence. In zones near stations, provision drops to 60% in Zone 1 around Rickmansworth station and 80% in Zone 2. For most uses, 20% of car spaces must have working electric vehicle charging, with a further 30% wired ready for future points.
