Landscape conservation: elements of protection

Protections Elements

• Areas with predominantly valued
landscapes“(art. 60 NdA Ptcp)
• Landscape protection of existing and
planned roads (art. 43 NdA Ptcp)
• Centers and cores of ancient formation:
the margins not occluded(art. 50 NdA

Landscape
Ptcp)
• Landscaped areas of interest for the
continuity of the green network (art. 60
NdA Ptcp)
Tutela degli assetti locali

• Agricultural landscape of historical and
cultural interest

• Provincial Ecological Network(art. 61
NdA Ptcp)
• Regional Ecological Network (art. 61
Ecosystem
NdA Ptcp)

• Priority areas for biodiversity (art. 61
NdA Ptcp)

• Areas destined to agricultural areas of
strategic interest (art. 56 NdA Ptcp)
• silvicultural - pastoral roads
Agricolture • Forests (Ex art. 142, D. Lgs 42/2004)

Environmental guidelines
From a judgment of environmental sustainability, development should be reduced provided the physical limits of the
municipal area, in recognition of the emerging constraints, in order to analyze the quantity and location of land

Key elements in the management of future possibilities in the planning

• Need for construction of an ecological network at the municipal level

• Central role of the hydrographic network within the landscape

• Protection and enhancement through networking of the
main stays of historical human settlements

• Maintainance of the integrity of the values of integrity and quality of perception

• Identification of forms and strategies of management and control of urban processes

• Ultimate protection of natural and anthropogenic land from the current forms of
hydrogeological instability

• Minimization the negative externalities engendered by human pressures on the
landscape
