2 Switzerland s wild-west underground 2

3 Underground: a fragmented legislation 3

4 Federalism: 26 cantons & 2500 communes

5 The swiss legal framework The federal laws assign the responsability for land-use planning to the 26 cantons and to the communes 1979: first federal law on land-use planning (LAT). 2019: LAT-revision: mention of the underground Delimitation of private and public domain is not solved! Art. 667 of the Swiss Civil Code (SCC) says:. The extension of the ownership extends to the full height and depth usefull for its exercise

6 Aviation Railway Road Energy Land-use planning Confederation Sectoral Plan Cantons Master Richtplan Plan Communes Land-use RichtplanPlan Building Permits

7 Kettiger/swisstopo, Stand: Sept Access to geological data according to cantonal regulation Regulation available Regulation for water No regulation Regulation in development

8 Parliamentary intervention Bundesamt für Landestopografie swisstopo Postulat K. Vogler : geological data of the underground The Federal Council is asked to facilitate the access to the geological data and information, permitting a better land-use planning of the underground. Response of the Federal Council ( ) a modification of the federal law on geoinformation will be proposed to facilitate the access of the geological data and information as well as the update of the cantonal laws the development of standards for the exchange of data and information will be provided by swisstopo the needs of the cantonal authorities will be analysed in the framework of 3 pilot-project with swisstopo the federal government will support the cantonal authorities for the development of the infrastructure and platform to collect and exchange geological data

13 Definition: geological data or information? According to the ordinance for the swiss geological survey and the federal law for geoinformation: primary geological data: measurements, data, loggings, analyses, lithological & geotechnical description of boreholes primary processed geological data: processed geophysical data, logs of boreholes Aarhus convention : access to environmental data secondary interpreted geological information: interpretation of geophysical data, correlation between boreholes, geological cross-section, geological maps, 3D-models Intellectual property rights: protected information 13
