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 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.
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 • 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.

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 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).
