From the Mining Remediation Authority, formerly the Coal Authority. The development high risk area marks recorded coal mining features at or near the surface: mine shafts and adits, shallow workings, mine gas and former opencast sites. Most planning applications there need a coal mining risk assessment; householder applications, changes of use and some minor works are exempt. Mine entry positions come from old plans and can be out by several metres, and unrecorded workings can exist anywhere in the coalfield.

Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.

Root protection areas reach up to 15 m from a large tree, so an extension or new foundations this close usually needs a tree survey. Only some councils publish their single trees, and a position can be approximate: the order at the council is the definitive record, and no tree shown is not proof there is none.
