Building on floodplains destroys natural barriers that help manage water flow, increasing the likelihood and extent of flood damage. The development of these areas leads to more runoff due to impermeable surfaces, worsening the effects of floods. Ultimately, this practice contributes to greater risks and detrimental consequences for communities. ;
