The mission of the Planning and Sustainable Department is to manage all policies and plans related to the Town’s physical environment (water, soil, air), to ensure the implementation of the Green Plan, to carry out investment projects related to municipal infrastructure and facilities and to plan the Town's urban development.

  • developing and recommending policies and guidelines for planning, sustainable development and infrastructure management;
