Normtraject primaire waterkering
What this layer shows
The normtrajecten of the primaire waterkeringen from the Nationale Basisbestanden Primaire Waterkeringen (NBPW). For each dijktraject the Besluit kwaliteit leefomgeving (Annex II) sets an omgevingswaarde, as a flood probability or as a probability of failure per year, which the defence must meet by 2050 at the latest, and alongside it a signaleringsparameter indicating when a reinforcement has to be prepared. In the NBPW data these still carry their old Waterwet names: ondergrens and signaleringswaarde. Trajecten are identified by their statutory traject number and not by a name; the norm values themselves are in the attributes of the traject.

Water
Everything you discuss with the waterschap and the province: the legger with flood defences, waterstaatswerken and protection zones, the normtrajecten of the primaire keringen, the peilbesluit areas, the KRW water bodies of Rijkswaterstaat, the ROR risk areas and the waterwingebieden, grondwaterbeschermingsgebieden and boringsvrije zones. Not every waterschap supplies every layer, so an empty result is no proof that no zoning applies.
