Coal mining legacy in West and South Yorkshire
Bradford Council notes a legacy of past coal mining in its district, and Sheffield asks for a Coal Mining Risk Assessment where a new building or substantial extension is proposed in a Development High Risk Area. Shallow workings and old mine entries can change foundation design, so the structural calculations need to take the assessment into account.

Flood risk and drainage in Hull
Hull City Council states that 95% of the city is within Flood Zone 3a. Its sustainable drainage guidance asks major developments to limit surface water runoff, including a 50% reduction on previously developed sites, so drainage design and surveys of existing drains matter on Hull projects.

Yorkshire Water and Anglian Water
Yorkshire Water provides water and sewerage services across most of the region, while Anglian Water’s area begins at the Humber north of Grimsby. Yorkshire Water’s consent is needed before building over or within 3 metres of a public sewer, and it will not allow building over manholes or near pipes larger than 225mm or deeper than 3 metres.

Leeds City Council confirms that some areas of Leeds have been identified by UKHSA as radon Affected Areas. Where the radon potential at a site is high enough, new buildings and extensions need basic or full radon protection under the Building Regulations.

HMO controls in Leeds
Leeds has an Article 4 direction covering areas including Headingley, Hyde Park and Woodhouse, Kirkstall, Chapel Allerton and Armley, where converting a house into an HMO needs planning permission. Letting an HMO also brings duties such as a fire risk assessment for common parts and regular electrical and gas safety checks.
