The variation to the Hydrogeological Planning Plan presented by the Municipality of Olbia was approved yesterday by the Regional Council.
Preliminary to the design of the works to secure the city from the risk of hydrogeological disaster, the study mapped the danger that the 37 thousand square kilometers of the municipal territory run in the event of flooding with the aim of identifying the critical issues on which (not) to build the plan of the works.
The general variant study, approved by the executive on the proposal of the president, Alessandra Todde, has re-evaluated the vulnerability parameters, downgrading the dangerousness of many areas of the city that, after the fury of cyclone Cleopatra, in the PAI drawn up in 2015, had been classified as high hydrogeological risk areas (as a precaution) where any type of building work was banned and which have now gone from Hi4 to Hi*, critical but not dangerous and only under special surveillance , leaving the discretion of building to the municipal urban planning plan.
The new PAI frees three quarters of the city from constraints, reducing the square kilometers, from seven to approximately three, of the areas at high hydrogeological risk, favoring urbanization.
