This necessitates raising the safety level for the longer term.It has been recommended to plan for a flood risk with a return period of 500 years.Organisation to maintain the dike Other problems with the dike relate to organisational structures. A single authority needs to be assigned with overarching responsibility for the dike, its management and the works in and on the dike in the future.Implementation plan The Adaptation Fund has earmarked 823 billion Colombian pesos (332.5 million euro) to implement the 'Plan of Aguablanca Jarillón and Complementary Works' (PJAOC). It is responsible for repairing and rebuilding infrastructural works damaged by the major floods of 2010-2011 caused by the La Niña effect.
The safety level needed in those days no longer satisfies today’s standards.
Economic boost More than 900,000 people who live in Cali’s Agua Blanca district will benefit from implementation of this plan.
The Dutch engineering firm Royal Haskoning DHV presented its final recommendations for reducing flood risks in the Aguablanca district of the Colombian city of Cali on December 7th, 2012 in the presence of representatives of the Dutch embassy in Bogota.
The recommendations were handed to Rodrigo Guerrero Velasco (Mayor of Cali), Jorge Londoño (Chairman of Fondo Adaptación (Adaptation Fund)), Carmen Correa Arevalo (Managing Director of Fondo Adaptación) and various local authorities including the Corporación Autónoma Regional del Valle del Cauca (CVC).
Over the past fifty years the area behind the dike has developed from an agricultural into a heavily urbanized setting.
Economic growth is set to increase considerably in Cali and the surrounding area, and the same goes for more regional developments in the upper reaches of the Cauca River.
