Abstract: “A problem solving of floods in urban area is a complex process. There is no a generale solution can be used to solve the problem of floods in any cases. The solution of floods should be adjusted to the characteristic of flood fenamenon in a certain location. There are some alternative solutions could be created to solve the problem, it is however the best decision should be found out. This research contributes tocarry out an optimisation model to find out the most effective and efficient solution. The concept of optimisation is based on value for money approach using value engineering tool to choose the best solution from any possible alternatives. The result shows that the best solution is an alternative succeding to avoid the flood with the highest impact in disturbing socio economic activities.”
