Technical assessment in flood areas to be deepened by CSP

The Hazard Synthesis Map identifies areas with different degrees of penalties (high, medium, low and other types of penalties) based on the hazard classification of geological, hydrological and snow or forest phenomena.

Building interventions in areas classified with other types of penalties are regulated by Article 18 of Annex B (implementation rules) of Provincial Law no. 5 of 27 May 2008 (Approval of the new provincial urban plan).

Further specifications and provisions concerning such interventions are contained in the document "Indications and clarifications for the application of the provisions concerning areas with high medium or low penalties and areas with other types of penalties", approved with Provincial Council Resolution no. 1317 of 04 September 2020 and subsequently kept updated.

These provisions envisage that, for the interventions subject to the application of the regulations relative to the Hazard Synthesis Map (CSP) falling in areas to be deepened (APP) linked to torrential phenomena "not reticulated", a specific study, or compatibility report, must be carried out, aimed at deepening the dynamics of the expected events and at identifying, with reference to the area subject to intervention, the corresponding hazard according to the classes envisaged by the resolution of the Provincial Council no. 2759 of 22 December 2006, as amended, as well as the relative penalty according to the grades provided for by the resolution of the Provincial Council concerning the "Technical provisions for the drafting of the 'Hazard summary map' in implementation of the provisions of Article 14 of Provincial Law no. 5 of 27 May 2008 'Approval of the new provincial urban plan'".

Considering the penalty class resulting from said studies, the land use regulations corresponding to the respective penalty are applied to the area of intervention, as well as the relative clarifications contained in this document.

The study is submitted directly to the technical evaluation of the competent structure for the type of hazard, which, with reference to flood phenomena, is the Mountain Basin Service.

Private and public entities intending to carry out building works in areas to be deepened (APP) by flooding phenomena of the Hazardousness Summary Map.

The application for technical assessment must be submitted to the Mountain Basin Service by filling in the appropriate form prepared by the administration and attaching the study, or technical report, and other documents deemed necessary.

The documentation must be transmitted by certified email to serv.bacinimontani@pec.provincia.tn.it or by PiTre interoperability (for municipalities and other public entities).

The application must be submitted exclusively in digital format.

The following must be attached to the application form

• compatibility study in digital format, digitally signed by the appointed technician
• project drawings of the intervention in digital format, digitally signed by the appointed technician;
• photocopy of an identity document of the applicant(s) (if the application is signed with a handwritten signature).

The technical assessment is issued by a determination of the Director of the Mountain Basin Service.
