Red de espacios urbanos estratégicos en la isla de Tumaco - Nariño

Abstract

Tumaco Island due to its geographical location, it is connected to the so-called Pacific ring of fire, the epicenter of the greatest global seismic activity, which is why it is exposed to the impact of natural phenomena such as flooding due to the increase in sea level and threats from tsunamis. Likewise, it faces urban growth due to excessive growth, irregular and informal occupation on the coastline and the destruction of endemic ecosystems such as mangroves, disappearing the natural containment barriers, increasing the vulnerability of the island. The objective of this research is the proposal of a network of strategic urban spaces, which, through projective research with a quantitative approach, which after analyzing the bibliographic sources, plans and programs of the study area, could be characterized and identified the areas to intervene, evidencing that the island of Tumaco does not have urban connection zones or zones to save people in case of natural disasters. As a result of the analysis, a design with a resilient approach oriented to the need for human protection is proposed, promoting social life, through articulated connections between the points of the network. The proposal will be raised through four phases of intervention linked to the design strategies (safeguard, flow, recover, integrate), the first phase contemplates the coastal network made up of four boardwalks with a total area of 4,700 m2, the second phase includes the network strategy to save people that is made up of six zones with a total area of 20,000 m2, the third phase is made up of three docks with a total area of 4,000 m2, according to the maritime connection network, finally the containment of mangrove barrier.
