3 Flood Prevention Methods for Cities
3 City Flood Prevention Techniques
Damage from high water impacts businesses in areas like Palm Springs North, FL, all over the world. Traditional flood prevention methods can be quickly overwhelmed in a large downpour. Innovative city planners are considering methods to stop flooding. These methods fall into the following general categories:
- Increasing the availability of natural flood defenses
- Installing improved systems for control of water
- Improving and maintaining sewage systems
1. Natural Flood Defenses
Natural methods for flood prevention are popular because they are self-sustaining and environmentally friendly. These methods include such large-scale projects as restoring rivers to their original channels and recreating floodplains lost to urban sprawl as well as smaller projects such as using permeable materials to build sidewalks or pavement.
2. Water Retention Systems
A variety of methods to hold or redirect flood waters have been created for urban areas. Some cities that experience regular flooding have installed large underground culverts to hold excess ground water. Other permanent forms of retaining high water until it can be harmlessly dissipated include raised embankments. Temporary sectional or frame barriers can enhance permanent flood defenses when needed.
3. Sewage Systems
Urban sewage systems are particularly vulnerable to being overwhelmed in a severe storm. Many cities are improving their water management systems by separating rainwater from existing sewage systems and water treatment plants. Maintaining existing sewage pipes and drains by clearing debris improves water flow and reduces the adverse effects of storm waters.
The severe damages caused by flooding have made flood prevention a priority for city planners all over the world. While these steps can make urban areas more resilient to the effects of high water, when flood waters hit, the services of restoration specialists can quickly put businesses back to work. These efforts can be improved by preventive measures such as raising electrical outlets, replacing plaster board with water-resistant materials and installing waterproof seals on doors and windows.
