Title: Site of Conservatory of natural spaces in Pas-de-Calais Description: A Natural Space Conservatory Site (SCEN) is one of the protected natural areas (ENPs) which are designated or managed in an international, Community, national or local context with a view to achieving specific objectives for the conservation of natural heritage.Conservatoires of natural areas contribute to the preservation of natural heritage and landscape through land control or control over the use of a network of sites. Depending on the local characteristics, regional conservatories and departmental conservatories are distinguished. As part of the national database on protected areas, only sites fully acquired and/or for long-term rental (emphyteotic lease and contract over 30 years) are taken into account. These are sites for which the Conservatoires have full land control. They are classified as IUCN’s Ia, III, IV, V or VI categories (according to regulations and management objectives established).Legal References: Articles L414-11, D414-30 and D414-31 of the Environmental Code.

The precautionary strips are identified behind the protective structures to limit the risks in case of breakage or overflow. The main interest of these works must remain the reduction of the vulnerability of existing ones. Also, these precaution strips prevail over the hazard. In these precautionary bands, the principle of inconstructibility is retained.

Title: The Lawe PPRN Surface Issue Description: Generally speaking, the stakes are people, property, activities, cultural or environmental heritage elements, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability”. This object class brings together all the issues that have been addressed in the RPP study. An issue is a dated object whose consideration depends on the purpose of the RPP and its vulnerability to the hazards studied. A PPR issue can therefore be considered (or not) depending on the type or types of hazard being addressed. These elements form the basis of knowledge of the land cover necessary for the development of the RPP, in or near the study area, at the time of the analysis of the issues. The data on issues represent a (figible and non-exhaustive) photograph of assets and individuals exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the issues are recalculated as necessary with up-to-date data sources.

The coastal path must allow pedestrians to reach the shoreline of the sea and to walk as long as possible along the coastline. It refers to the entire route open along the sea. It does not have a single legal status because it consists of sections of a different legal nature. Depending on the nature of the land bordering the public maritime domain, the trail passes over the public domain of the State or local authorities, or private property. The entire coastal pathway includes the pedestrian-open pathway, the short-term study or accessible trail line, and the inaccessible coastline. The sections are one of the main elements for identifying the location, route and use of the coastal trail. This route concerns the department of Ille and naughty and partly the Côtes d’Armor for the perimeter of the Rance.

Title: Lawe PPRN amalgamated hazard zone Description: Area exposed to one or more hazards represented on the hazard map used for risk analysis of the RPP. The hazard map is the result of the study of hazards, the objective of which is to assess the intensity of each hazard at any point in the study area. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. For multi-random PPRNs, each zone is usually identified on the hazard map by a code for each hazard to which it is exposed. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure). Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards. Some areas within the study area are considered “no or insignificant hazard zones”. These are the areas where the hazard has been studied and is nil. These areas are not included in the object class and do not have to be represented as hazard zones. However, in the case of natural RPPs, regulatory zoning may classify certain areas not exposed to hazard as prescribing areas (see definition of the PPR class).

Description: As part of the implementation of the action plan for the marine environment, the Cerema water, sea and rivers, carried out for the Ministry responsible for the environment, a national study in metropolitan France to identify the level of equipment in fairing areas of marina, mooring areas and private boatyards in order to assess their respect for the environment. The data collected for the Pas-de-Calais department made it possible to build a layer of geographical information. The latter locates on this department, in the form of points, the sites (recreational harbours, berths and private boatyards) whether or not equipped in fairing areas. The layer also characterises the level of equipment in fairing areas at each of the sites identified and, for those equipped with a fairing area, the type of effluent treatment.

The Water Supply and Management Schema (SAGE) is a collective planning document, for a coherent hydrographic perimetre, setting general objectives for the use, development, quantitative and qualitative protection of the water resource. It must be compatible with the Schema Water Supply and Management Managers (SDAGE).The perimetre and the time frame in which it is developed are determined by the SDAGE. In default, it shall be stopped by the prefets of the department, the case being decided on the proposal of the territorial collectivites of interest. The SAGE is established by a Commission Locale de l’Eau (CLE) representing the various actors in the territory, subject to a public investigation and is approved by the Prefet. He has a legal framework: the Regulation and its cartographic documents are enforceable against third parties and decisions in the field of water must be compatible or made compatible with the plan for the supply and sustainable management of the water resource. Planning documents (scheme of territorial coherence, local planning plan and municipal map) must be compatible with the objectives of protection defined by the SAGE. The schema departemental of the carrieres must be compatible with the provisions of the SAGE. The reference texts are Articles L.212-3 to L.212-11 of the Environmental Code and circular DE/SDATDCP/BDCP/No. 10 of 21 April 2008. Source: GESTEAU Vintage: 11/09/19 Dissemination: Open

Please cite the Census and ACS when using this data.Data Note from the Census:Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The effect of nonsampling error is not represented in these tables.Data Processing Notes:This layer has associated layers containing the most recent ACS data available by the U.S. Census Bureau. Click here to learn more about ACS data releases and click here for the associated boundaries layer. The reason this data is 5+ years different from the most recent vintage is due to the overlapping of survey years. It is recommended by the U.S. Census Bureau to compare non-overlapping datasets.Boundaries come from the US Census TIGER geodatabases. Boundary vintage (2014) appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines clipped for cartographic purposes. For census tracts, the water cutouts are derived from a subset of the 2010 AWATER (Area Water) boundaries offered by TIGER. For state and county boundaries, the water and coastlines are derived from the coastlines of the 500k TIGER Cartographic Boundary Shapefiles. The original AWATER and ALAND fields are still available as attributes within the data table (units are square meters). The States layer contains 52 records - all US states, Washington D.C., and Puerto RicoCensus tracts with no population that occur in areas of water, such as oceans, are removed from this data service (Census Tracts beginning with 99).Percentages and derived counts, and associated margins of error, are calculated values (that can be identified by the "_calc_" stub in the field name), and abide by the specifications defined by the American Community Survey.Field alias names were created based on the Table Shells file available from the American Community Survey Summary File Documentation page.Negative values (e.g., -4444...) have been set to null, with the exception of -5555... which has been set to zero. These negative values exist in the raw API data to indicate the following situations:The margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate.Either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.The median falls in the lowest interval of an open-ended distribution, or in the upper interval of an open-ended distribution. A statistical test is not appropriate.The estimate is controlled. A statistical test for sampling variability is not appropriate.The data for this geographic area cannot be displayed because the number of sample cases is too small.
