I understand that the development in question is an unfinished housing development, which is in private ownership and has not yet been taken in charge. Longford County Council had initiated legal enforcement proceedings against the developer to have the estate completed satisfactorily.
This is a matter for the local authority to address, but I understand that a programme of work to ensure resolution of outstanding issues on this development for the residents is currently being finalised, including addressing the lack of public lighting in the development.
