Public footpath 17 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Also on the record
Radon affected area, class 3; Inside the Harpenden built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site
