The document with which the Lombardy Region, with DGR n. VII/11045 of 8.11.2002 (published in the BURL of 21 November 2002, 2nd Extraordinary Supplement to n. 47), approved the criteria for the drafting of the landscape examination of the transformation projects of the Lombardy territory, concerns the definition of the methods for determining the landscape sensitivity class of the site and the degree of landscape impact of the project.

This method, to be used in areas of the regional territory not subject to specific landscape protection, allows the definition of the level of landscape impact of the project which, in the first instance, is estimated by the proponent of the intervention and is evaluated by the competent body issuing of building permits.

The document refers to the Regional Territorial Landscape Plan of 2001, which was updated, modified and integrated with the Regional Territorial Plan approved by the Lombardy Region on 19 January 2010.

The new landscape legislation, in the text recently approved by the Regional Council (see articles 35-39 of the Regional Landscape Plan legislation), explicitly confirms the criteria approved with the "guidelines for the landscape examination of projects": therefore for the entire regional territory - with the exception of the areas subject to specific landscape protection (for which the procedures dictated by the legislative decree of 22 January 2004, n. 42 and by the regional law of 11 March 2005, n. 12 apply) - it is mandatory that the projects that modify the state of the places and the external appearance of the buildings are subject to a landscape assessment by applying the criteria and guidelines dictated by the regional resolution.

• in the case of foreign construction companies based in an EU country, in the appropriate space of the relevant unified regional forms on the Single Owner Form, considering the existence of the obligation to register with the Building Fund, the registration code with the Building Fund will necessarily be indicated while the obligation to register with INPS and INAIL does not apply the documentation certifying the regularity of the Company's contributions must be delivered to the competent bodies of the country of origin in the native language and translated into Italian by an interpreter, subject to verification by the Client in his interest.
