For a driveway?
There are controls over hard surfaces such as driveways, aimed at reducing water run-off which contributes to flooding. Planning permission will generally be required for the impermeable surfacing of front gardens of areas that are more than 5 square metres.
Further guidance on making an application and information needed to register an application can be found here.
Guidance in respect of the types of surfacing that are permitted can be found on the Communities and Local Government website.
If neither of the above apply, planning permission is not normally required to drop the kerb, provided that a driveway or part of a driveway is laid in a porous material at the same time.
Looking to create an access?
Permission for the new access is still required from East Sussex County Council Highways. Further information on dropped kerbs can be found on the East Sussex County Council Highways website.
If you want to create an access onto a classified road as part of your proposal then planning permission will be required. You can find out here whether your road is classified.
