World Tree Day
Through trees we are able to connect with nature, obtain colour variations, form and texture that enrich and add aesthetic value to buildings and the urban space. They offer CO2 fixation and O2 production, reduce wind, increase shade and atmospheric humidity in the summer, decrease energy consumption and reduce pollution. For these reasons, in Alta de Lisboa, 1/3 of the area is covered with green spaces, these being divided into the following groups:
- 3 Large Parks – 512,185 m2
- Parks of average size, gardens and landscaped areas – 69,195 m2
- Protection to the roadways from traffic – 121,360 m2
- Green spaces resulting from the implementation of buildable areas, occupying public places or framework areas of buildings.
Relative to the three large urban parks, they are as follows:
- Parque Sul – 7.6 hectares
Designed by the Spanish architect Isabel Aguirre, it is part of the entrance of the urbanisation, involving the initial section of the Eixo Central and will have an emblematic and formal character. It will have two fields for rugby and easy accessibility, either by car or by public transportation, including pedestrian and cycling circuits which connect to the remainder of the city. The start of construction is scheduled for the end of 2007.
- Parque Oeste or Grande Vale– 24 hectares
Designed by the Spanish architect Isabel Aguirre, it is the largest new urban park in the urbanisation and one of the largest in Lisbon. It is already partially constructed (almost 10 hectares), constituted by two distinct areas, one dedicated more to informal recreation, marked by a great central lake, which also has a function of controlling and minimising environmental impacts and the other is dedicated more to sports where an athletics track is to be constructed. Its conclusion is scheduled for the end of 2007.
- Parque das Conchas and Quinta dos Lilases – 22 hectares
Being an existing park, it constitutes a space with great play and recreational potentialities, where the great central lawn, the bush and the area corresponding to Quinta dos Lilazes is highlighted, and is of a more intimate nature. It was the object of an intense regeneration realised by SGAL, as a project of the Lisbon City Council.
