L'ingegnere forestale Patrick Luraschi, capo del V Circondario Vedeggio Luganese e Valcolla, rassicura gli abitanti delle Valcolla, interessata nei giorni scorsi da alcuni movimenti franosi.
Il tecnico comprende bene che le ultime piogge hanno allarmato i cittadini, anche dopo i fatti di cronaca degli scorsi giorni che hanno visto pure alcune momentanee evacuazioni.
La Valcolla è una regione fragile ma non abbandonata, ha detto Luraschi, "è un territorio caratterizzato da una roccia frastagliata relativamente debole , dove piccoli movimenti sono all'ordine del giorno ma non devono destare preoccupazione". I monitoraggi confortano gli uffici cantonali e lo stesso ingegnere ricorda come siano stati messi in cantiere dal 1881 ben 54 progetti di risanamento di una situazione labile dal profilo idrogeologico, altri sono in corso o previsti.
Il maltempo ha messo in apprensione non poche persone in tutto il Ticino e sono state molte le sollecitazioni pervenute al servizio geologico cantonale e ad altre autorità. Consulenza viene però offerta anche da diversi studi di ingegneria.
