For example, according to national law, natural areas can be developed only if the area is covered by a SCoT. Such incentives have been further strengthened by the requirement that developed areas that are not covered by a SCoT cannot be expanded starting from 1 January 2017 onwards. To encourage the adoption of SCots, the State set up annual calls for proposals starting in 2010 to increase participation in rural territories with limited human and financial resources to draw up SCoTs. The PADD is the policy document which establishes the main thrusts of territorial development for the next 15 to 20 years, the DOO is the technical document which is enforceable against local documents such as the local housing programmes (Programmes locaux de I ’habitat), urban mobility plans (Plans de deplacements urbains), local urban planning plans (Plans locaux d’urbanisme) and municipal maps (Cartes communales).
