HUNTON BRIDGE H33 – Land at Mill Place H33 – Land at Mill Place, Watford Road SHELAA Reference: NSS10 Size: 0.6ha Proposed use(s): Residential Indicative Dwelling Capacity: 10 Phasing: 0 – 5 years Greenfield/Brownfield: Brownfield Green Belt / Grey Belt: The site is considered to be grey belt. Given that the site is not edge of settlement, its brownfield nature and grey belt categorisation, the site has been retained in the Green Belt Main Development Requirements: • Indicative dwelling capacity of 10 • A 10-metre buffer area is required between development and the River Gade to the east of the site Site Constraints and Other Requirements and Considerations: Access, Highways and Sustainable Transport • There are two existing accesses into the site from the A41. Engagement with HCC Highways at the earliest stage is strongly encouraged. An Access Strategy and Transport Assessment would likely be needed at a planning application (and preferably pre-application) stage Flooding • The Site is adjacent to a Main River (River Gade/Grand Union Canal) which is classified as Flood Zone 3b. A 10-metre buffer would be required between residential development and the river • There is a risk of groundwater flooding due to the shallow ground water level. Development would be subject to appropriate mitigation measures to address the risk of groundwater flooding • The council’s Level 2 SFRA (2026) has concluded that development should be steered away from the areas of highest surface water flood risk in the 100 year plus climate change flooding event. A Flood Risk Assessment (FRA) must be submitted at the planning a pplication (and preferably pre-application) stage • The site falls within the Groundwater Source Protection Zone 1 (GPSZ1) which may limit the use of SuDS, deep foundations and below ground development. A preliminary risk assessment is required at the planning application (and preferably pre -application) stage to determine whether there is contamination, and whether remediation works would be needed Historic Environment • There are Grade II Listed Buildings close to the northern and southern boundaries of the site (Bridge over the Grand Union Canal to the south and North Grove Lock House to the north). The council’s high-level Heritage Impact Assessment states that the site’s development would have a minor adverse impact on the historic environment although sets out that it is likely that the impact could be mitigated through good design including appropriate scale, massing and positioning of development, which may include s etbacks of housing from the canal and use of appropriate landscaping boundary treatments • A Heritage Impact Assessment/ Heritage Statement should be submitted at the planning application (and preferably pre -application) stage , including details of mitigation measures to reduce the impact on nearby heritage assets Landscape • The council’s Landscape Sensitivity Assessment classified the site as medium-high sensitivity to built development. It is also classified that the site as having a high sensitivity to the historic character. As such, the submission of a Landscape and Visual Impact Assessment should be submitted at the planning application (and preferably pre-application) stage Green Infrastructure, Biodiversity and TPOs • HCC Ecology state that illuminating waterways and riparian margins should be avoided. • A Local Wildlife Site is located adjacent to the east of the site. Given the close proximity to the Local Wildlife Site, an Ecological Impact Assessment will be required at the planning application (and preferably pre-application) stage Environmental Health and Pollution • Noise and air quality issues caused by the site’s proximity to the A41 may have an impact on the site and its future occupiers and as such noise reduction measures should be considered as part of the design. Relevant assessments and reports, including details of mitigation measures would be required at the planning application (and preferably pre-application) stage. Mineral and Waste • A Site Waste Management Plan (SWMP) will be required to support any proposal at the planning application stage. • The site is located on an area of Historic Landfill (reference: EAHLD12879). The presence of and risk from contaminative materials should be considered at the earliest stage. The submission of a Land Contaminati
