The area extends from Flamborough Head, East Yorkshire, to Felixstowe, Suffolk, and 200km (124 miles) out to sea.
Plans will be drawn up by the Marine Management Organisation (MMO) over the next two years to co-ordinate the development of all marine activities.
They will serve as a blueprint for what activities can be licensed in the new marine plan area.
The Flamborough-to-Felixstowe zone will be the first of 10 that will eventually form a comprehensive marine planning system around England.
They will aim to bring "joined-up" planning to marine activities including wind farms, oil and gas exploration, cable laying, commercial shipping, fishing and recreational use. Read the full report here.
