PROJECT DESCRIPTION

The Environmental Impact Assessment (EIA) regards the final project of the construction works involving the 2nd functional lot of the shipbuilding area in the eastern outside entrance of Cagliari Port. These works aim at improving the industrial, artisan and commercial settlements in the shipbuilding sector with particular attention to megayacht refitting and pleasure boating.

As described in the Port Development Plan, the project involves ground works in the eastern block and constructions in the port basin nearby.
The basin works include the extension of the current coastline of about 70 cm, the construction of an internal channel in the navigable part dredged at 3.50 m above sea level and the implementation of a system able to protect the harbor from the incoming wave motion.
The latter intervention consists of an overflow pier with a trapezoidal layout and a breakwater quay (western pier) exhibiting a circular shape. Moreover, the demarcation of the new dock is completed on the eastern side by the construction of another quay.

Additionally, the seaside project regarding the shipbuilding area of Cagliari Port requests also the opening of a gap of about 80 m on the eastern pier in order to create an independent access for the ships directed to the new dock and the dredging of the access channel and the front area for a width of 100 m and a depth of 5.00 m above sea level.

PROJECT CHARACTERISTICS

Taking into consideration the typology and location of the project, the aquatic environment is the main component affected thus subjected to studies and analyses, especially in relation to the following aspects: water supply and discharge and implementation of new impermeable surfaces which influence the qualitative and quantitative behaviour of the system disposal structure - receptor.

In this context VDP proposed waste water monitoring actions to control the correct management and operational activity of the system.
For what regards the extension of the current coastline, the construction of the internal channel and the dredging works, a detailed analysis was deemed necessary in order to evaluate the impacts on the vegetation and fauna components and aquatic and terrestrial ecosystems.
Furthermore, a landscape inclusion design was carried out to estimate the effects on the surrounding landscape caused by the project works.
