Specific Modification of the General Metropolitan Plan and Partial Plans of the Parc d'Activitats and Gabrielistes II sectors in Viladecans

Planning that allows the opening of the Riera de Sant Climent to the Llobregat delta with the creation of the great park of the Marina.

Planning of the urban front from Viladecans to the Llobregat delta

The new organization of the front of the Viladecans municipality with the Llobregat delta agrarian park, structured from the recognition of the Sant Climent stream. A large equipped green area (Marina park) is organized around this, thanks to the concentration of residential and commercial buildings on one side of the park (Vilamarina complex) and that of industry on the other (Activity park).

The city of Viladecans is located in the Baix Llobregat region, in the metropolitan region of Barcelona. Originally seated on the Carretera de Barcelona, ​​the current C-245, which runs parallel to the sea line joining the towns on the left bank of the Llobregat with those on the edge of the delta, had a linear urban development until the 1950s, with a clear tendency to connect its urban area with that of the other neighboring towns along the C-245.

The demographic explosion of the sixties and later, as well as the establishment of large industries, modified this trend, promoting growth in an oil slick. However, the geographical and structural conditions of the environment weighed down this expansion, towards the mountains through the orography itself, towards the sea through the routes of the major infrastructures (highway and rail), and towards the east due to the presence of the Riera de Sant Climent.

Viladecans, like most cities on the left bank and on the cornice of the Llobregat delta (Sant Vicenç, Santa Coloma de Cervello, Sant Boi, Gavá, Castelldefels, etc.) has not only seen its expansion hampered due to the streams, rather, historically it has turned its back on them until they ended up becoming open-air sewers where sewage was discharged and debris from demolition accumulated. However, in the case of Viladecans, the demographic growth of the last ninety and first two thousand, made the municipality reconsider the need to grow beyond the stream and therefore to rethink its role in the city as a whole.

Thus, the expansion of Viladecans was proposed having the Riera as the axis of its growth towards the east and as the guiding thread of its expansion towards the south. Our urban proposal tried to establish a system of parks inside the city, taking advantage of the gaps that the city itself had generated in the process of occupying the territory. These voids, stitched together by the stream, became the new free spaces of the city and allowed a pedestrian continuity, previously unimaginable.

The general project was based on interpreting the stream as a natural connecting corridor between the agricultural park and the mountain through the city, turning it into an urban park, incorporating when possible the discovered sections, recovering its native vegetation, and converting the covered parts into wooded walks.

The park was planned, based on its nature as an ecological corridor, as a succession of longitudinal groves of different riverbank species that accompanied the various paths for pedestrians and cyclists. Specific work was done on hydraulic corrections that would improve the seasonality of the stream and eliminate the risk of inopportune floods, and the channel was vegetated with native species. The complex formed a new north-south urban axis and also connected the consolidated part of the city with the new growths to the east, through the layout of new communication routes that respected the continuity of the park.

In the last urban stretch of the Riera de Sant Climent, just between the old C-245 road and the highway, the urban border before the agricultural park, the city had the opportunity to develop an entire strip of territory parallel to the highway.

The ordination unified the provision of public green of the sector around the stream and determined two areas of development, to the west a housing, commercial and tertiary area, and to the east, a sector of new industrial and technological development.
