Hard mapping work for designation of new Nitrate Vulnerable Zones in England - WT03010

Description
HARD MAPPING WORK DESIGNATION OF NEW NVZs IN ENGLAND

1. Background -
The map produced by WS 198/8/98 is hydrologically accurate and covers around 55% of England with NVZs. The problem is that the boundaries of the NVZs do not equate neatly to the boundaries of individual fields and landscape features. To be workable and enforceable, NVZ boundaries cannot straddle individual fields. The hard mapping process (under this project) therefore needs to convert the soft boundaries into boundaries which follow field-boundaries, so that individual farmers can see precisely which fields are in or out of the NVZ area.

2. Objectives -
a) To complete ‘hard’ (detailed, field-boundary level) mapping of proposed new Nitrate Vulnerable Zones (NVZs) working from the end-product ‘soft’ (hydrological boundary level) from WS 128/9/98, using detailed mapping rules as specified by DEFRA.
b) To produce hard copy and electronic end-product maps as specified by DEFRA suitable for publication in Statutory Instruments, inspection by the public, as a basis for an appeals mechanism and suitable for integration into wider guidance for farmers.
