This research aims to present the development and results of the first phase to the implementation of the “sustainable complete streets” in a pilot project inside the “Sapiens Parque” Technological Park, with focus in multi-modal transportation (vehicular, pedestrian, bicycle), that include elements of environmental, social and economic sustainability, related to planning and urban cadastre, integration between underground infrastructure, community and environment programs and resource utilization. The "Joint Trench model" presented replace facilities from the street and concentrates all these in the sidewalk and bike lane, in an underground system, reducing the interventions in the street during the construction, maintenance, operation and expansion of these facilities. This underground system replace the individualized construction of natural gas pipeline, potable water, fire fighting system, telephone, cable TV, data, electricity - low and medium voltage and public illumination systems and encompasses all of these facilities in an only trench in the sidewalk, inserting these in a bay made recycled plastic, designed by the concept of "fail-safe device”. The deployment of these facilities may also occur in the same period, or if necessary, at different times, thus creating flexibility to the system. The model also proposes the use of bike lane to implementation of sewage facilities, high-pressure plastic pipelines and main water, and attachment a “rain garden” system for collecting storm water, aligned with the sustainability criteria, since that collects, stores and filters water from the rains for reutilization or return clean water to the nature. The underground system is designed with the “zero waste” conception in your construction and operation, due that all material the bay and interconnection boxes were made from plastics and concrete derived from the urban waste, produced by community and environment programs. Recycled gravel from bricks and concrete construction waste are used to create a base of the plastic structure and the filter to the drainage system. To the operation, in case of maintenance, is necessary remove only the specifics concrete paver blocks in the sidewalk and the sand that cover the bay. After the maintenance, the same material is reused.
