2. Urban planning: a definition
We can define the sum of matters that contribute to the
transformation of the physical environment of the city as
"territorial production system
Urban planning can be defined as the set of governance
practices (in their economic, legal and technical dimensions) that
through the allocation of land use (zoning), interacts and tries to
regulation of the system of territorial production
The main function of the urban plan at (local) municipal
level is therefore the control of territorial transformations through
the formal allocation of land uses, where different rules regarding
the potential construction and implementation of infrastructure and
services.

3. Relationships between urban plan and
environment
• The environmental assessment of the outcomes of this process of
government regulation therefore must consider the technical and
operational characteristics by which an urban plan performs its function:
• in this case they have an irreducible spatial dimension.
• The planning regulation is done by organizing urban space with
• grids (which may have economic-operational nature: Mazza, 2007;
• symbolic rule: Rykwert, 2002;
• morphological design: Piroddi, 2000)
• The construction of the potential rules through which the planners should
(or rather, would like) organize the future city still needs a process of
elaboration and structuring of spatial knowledges, under which are then
performed the choices of the plan regarding the admissible transformations.

14. Environmental contexts
The environmental contexts are urban regions with a
distinctive uniform, under which it is possible to
distinguish the structural aspects of the different parts
of the territory. Each urban region are actually different
territorial morphology, forms of land use and
settlement areas, with a specific and recognizable
geographic landscapes characterized by specific
problems with regard to natural resources and human
settlements and the themes of regeneration and
sustainable development.

32. Conclusions
The construction of a single logical system of descriptive
environmental data allowed us to achieve some results.
The first was that of reducing the complexity resulting from very
large databases.
The second was to be checked at each step the set of
relationships that bind each other but interrelated phenomena so
difficult to be synthesized. It also permitted to make comparable
data on the state of the environment (and its potential for changes)
with data derived from the choices of the town plan.
Finally, he allowed the plan to organize knowledge in a way that
would be represented spatially (key issue since the evaluation
must be anchored on time to the geographical space).
