Port Regulatory Plan in a single system of the ports of Olbia and Golfo Aranci

The Port Regulatory Plan in a single system of the ports of Olbia and Golfo Aranci is in compliance with the Guide Lines for the drawing up of the P.R.P. (Art. 5 Law n°84/1994). It’s set up as a structural plan for strategic choices of spatial and functional layout and development of the port area, including for sustainability of the environment and cultural identity of the areas, in a single organisational vision projected over ten – fifteen years, aimed at optimal development of port activities, optimisation of urban and environmental contexts, integration with the territory’s communication networks.
The development projections regarding the intended use of the sections have been taken into consideration: industrial and commercial, passenger and cruising, fishing, recreational boating, shipbuilding. This is because the new Port Regulatory Plan must consider the multifunctional role of the port as a single resource: commercial travel (passenger and cargo), cruise traffic, recreational boating, shipbuilding, fishing and mussel processing, which represent the principal and strategic sectors of the port economy. The study has therefore been carried out considering two scopes, distinct but interdependent, of the operational port and of the interaction between port and city.
All possible implications that the realization of a PRP of such proportion could have at a territorial and environmental level have been evaluated in terms of criticality and of impacts. The fundamental characteristics of the criticality, and therefore of the scope of the architecture of the S.I.A., are thus delineated as a course to set to the future Constructive Phase of the P.R.P.
From the twofold evaluation and interaction of the engineering aspects of the P.R.P. and of the historic – environmental ones the direction of the Environmental Impact Study will be derived relative to the future Constructive Phase of the operations. The design of the relationship between works and environment, which considers the sensibility of the site to host the work, according to “threshold values” beyond which actions having impact on the “boundary project” are produced, is structured according to an Environmental Manager Scheme formulating possible operations (port, urban and service, recreational, tourist and environmental functions) in relationship to the functions and types of actions (development, conservation, upgrading, restoration, environmental protection). Finally, a SWOT analysis (strengths, weaknesses, opportunities, threats) was developed with a methodological approach to analyse the current state and potential evolutionary trend lines.

The proposition of actions can be characterised by the following areas:
1.  The water-front destined for recreational and tourist functions and to have greatest environmental range.
2.   Isola Bianca with particular care to its origins and to the central and “historic” tract.
3.   Isola Bianca for the head part and for all its body currently characterised by a high level of reception services.
4.  Porto Romano will be able to play a central role in the urban and tourist upgrading.
5.  “Light” access centre at the base of Isola Bianca.
6.   The industrial port at the moment offers itself as a structure holding the greatest potential for development of port activities.
7.   “Heavy” access centre corresponding to the industrial port
8.   The portion of Golfo Aranci closest to the base of the port and toward the urban area.
9.   Golfo Aranci  - The head area of the current port structure
10. Golfo Aranci freed from bundles of tracks toward the eastern end of the promontory.

From this twofold structural and environmental evaluation / projection emerges a constructive phase to the year 2020 of the direction of the Port Regulatory Plan in a single system that foresees:

1) Olbia Porto Isola Bianca: separation of light and heavy traffic on staggered levels and redistribution of land in relation to the security plans
2) Olbia Porto – Brin Mole – Bosazza Jetty – Via Genova: rooting of uses – seafront urban spaces with relative transit networks toward the recreational uses including for large displacement craft on the facing water expanses.
3) Pedestrian accessibility and use of the seafront areas: valorisation of the archaeological finds in Porto Romano and renaturalisation of the internal canal waters.
4) Olbia: Sub-channel tunnel on the Porto Vecchio
5) Golfo Aranci: theme and ecological park in the former railway areas on the slopes of Cape Figari
6) Golfo Aranci: Refunctionalisation of the port structures and of the service road system infrastructure
7) The three green loops:
First Green Loop: renaturalisation and valorisation with cultural (archaeological) walks of Porto Romano connected to the Fausto Noce Urban Park by reclaimed and upgraded drainage channels  Second Green Loop: Olbia seafront from via Genova to the Peschiera di Poltu Quatu
Third Green Loop: Disused railway areas under the slopes of the Nature Reserve of Cape Figari in Golfo Aranci
