Long ago a local planning authority granted planning permission and
issued a site licence for a site of mobile homes without ensuring that
the only access road to the site would be maintained to a satisfactory
standard. The access road is privately owned whose owners are
unwilling to resurface it and install surface water drainage so that
it can be adopted by the county council's highways department. The
access road is outside the boundary of the site licence, is not
covered by site licence conditions, and is not owned by the owner of
the site of mobile homes who therefore has no obligation to maintain
the access road. The site of mobile homes comprises 83 homes whose
mainly elderly residents occasionally fill the many potholes which is
only temporarily effective. What should the local planning authority do?
