Retrofitting Homes Against Floods

Adding features to homes can be employed for flood protection. Retrofitting options can include raising the foundation, building an impenetrable shell by reinforcing corners and openings, use of water-compatible materials, moving utility areas to the upper floors, elevating power sockets, adding roof access, installation of solar panels, and building bridges to the next door.
Climate Adaptation Effectiveness

The effectivity of this solution is dependent on the residential retrofitting design. In one instance, the construction of a floatable carport proved to be effective during the onslaught of a typhoon [1].

Evaluations

Economic / Financial Effectiveness
Low

Financing and land ownership are key constraints to retrofitting the homes of poor and low income households. In cases where a large scope of retrofitting is needed, new construction of disaster-resistant homes might be cheaper and more suitable. [3]

Technical Feasibility
Mid

Design and engineering expertise is required for this solution.

Social Acceptability
Low

Low-income homeowners generally do not see retrofitting as a priority due to low ginancial capacity and land-ownership issues. However, despite cost requirements, there is still demand for residential retrofitting with an estimated market of 15.6 million units [3]. Such demand could be due to many residents not having the option of relocating [2].

Environmental Impact
N/A

There is no direct environmental impact for this solution.

Mitigation co-benefit
