Why?<\/strong><\/p>\nIn terms of urban and landscape articulation, the tree-lined street is an archetype, a specific way to organise and qualify the urban fabric, providing the transition between the human scale and that of the built fa\u00e7ades, visual connectivity and comfort. The services intended by treelined streets are:
\n\u25ba Urban landscape: Its greatest recognition can be found in important urban models such as promenades, boulevards or avenues.
\n\u25baLiveability of public spaces: The tree cover contributes to the mitigation of urban heat island (UHI) effect by being an effective buffer and fixes pollutant particles.
\n\u25baEcological connectivity: The tree cover constitutes the main stratum for the ecological connection in the urban complex. The continuity of canopies facilitates the free movement and dispersion of fauna, mainly birds and insects. OFurthermore, vertical connectivity is ensured by the incorporation of the intermediate and lower strata.
\n\u25baWater cycle: The existence of vegetation is necessarily associated with the presence of permeable surfaces, continuous or isolated tree pits, causing water infiltration and reducing runoff.
\n\u25baClimate change adaptation and mitigation: Vegetation captures CO2 through the photosynthetic process.
\n\u25baCircular economy: The existence of trees implies the generation of quality organic waste (green waste) for the production of other derivatives such as compost or mulch. The pit surfaces allow the incorporation of these products to the soil as an improvement or as a weed control mechanism.<\/p>\n
How?<\/strong><\/p>\nThe tree-lined street is the area where most of the conflicts derived from the relationship between urban environment and nature take place. The integration of Grey and Green Infrastructure in the street requires a major effort of planning, design, implementation and management (maintenance).
\nIn this solution, the tree appears as the basic structural element for the configuration of the urban fabric. It is a shade tree, never a mere ornament.
\nIt is important to emphasize that the tree is a complex living being, composed of an aerial system, trunks, branches and leaves, and an equally hierarchical subterranean system of roots and radicles. The root system tends to occupy an area similar or superior to the crown projection, interacting in the urban space with the bases of the surrounding pavements. The roots need access to the moisture and nutrients of the soil; the leaves to the aerial carbon without which the trees cannot survive.
\n\u25ba OVERGROUND: The planting of trees in connectors of the Urban Green Infrastructure (UGI) Primary System will be carried out in continuous tip strips (minimum width 1,20 m). The tree size and its relationship with the facade should be taken into account, seeking relationships of scale and balance. In addition, the non-interference of the tops in their adult state must be guaranteed. The following table establishes the minimum dimensions that must be met in order to obtain a connector depending on the size of the tree.
\n\u25baUNDERGROUND: In addition to aerial development, in the arrangement of the tree-lined street it is necessary to check the compatibility of the pavement subbase with the root development. It must be a base that stabilizes the pavement, stimulates the deep growth of the roots and does not interfere with the urban service supply networks. The best option so far is Structural Soil, a mixture of gravel and topsoil forming a Soil-Stone system. The following table sets out the minimum dimensions of the pit cavity and the characteristics of the pavement subbase.<\/p>\n
