Simple download service (Atom) for the dataset: List of Natural Risk Prevention Plans (NRPP) in the department - Tarn

DATA GAME USED FOR A GEOIDE CARD

Risk prevention plans (RPPs) were established by the Act of 2 February 1995 on the strengthening of environmental protection. They are the essential instrument of the State in terms of risk prevention. Their objective is the control of development in areas exposed to a major risk.
The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate the occupation of land or its use by prohibitions of construction or requirements on existing or future buildings (constructive provisions, work to reduce vulnerability, restrictions on use or agricultural practices ...).
These plans may be under development (prescribed), pre-implemented or approved.
The RPP file contains a cover note, a regulatory zoning plan and a by-law. Other graphic documents useful for understanding the approach (hazards, issues, etc.) may be attached. Each PPR is identified by a polygon that corresponds to all the municipalities concerned within the scope of prescription when it is in the prescribed state; and the restricted zone envelope when in the approved state.
This geographical table makes it possible to map the existing PPRNs on the department.
Each existing PPRN document in the geographical table N_DOCUMENT_PPRN is linked using its GASPAR code in the format "ddd[PREF|DDT|DDTM|DREAL]AAAANNNN" (AAAA and NNNN correspond to the reference year and the serial number of the associated PPR procedure in GASPAR):
1. its administrative preparation (or revision) procedure managed in the GASPAR application, on the one hand,
2. its set of constituent digital spatial data described by metadata sheet N_PPRN_AAAANNNN (#0001495) on the other hand.
There are no MULTIRISKS in the TARN.
