Rain is an essential natural resource for our planet; however, summer showers can cause major problems for any city if they aren’t properly prepared for them. Costly damage and tedious traffic are just a couple issues that urban settings could encounter. Fortunately, your city can reduce its risk of harm—below, we share five ways cities can prevent floods.
Advocate for gardens, parks, and other green spaces in your community; they’re not only aesthetically pleasing, but green spaces are also key to overall urban development. It’s no secret that concrete can’t effectively absorb rainwater, which is why city sidewalks flood in the first place. On the other hand, grass, trees, and soil can soak up the excess rainwater, and your city can avoid flash flooding.
When constructing a new building, cities should select materials that are firm, but also allow water to pass through them. Porous asphalt and concrete, for example, are suitable substitutes for impermeable surfaces.
Submersible pumps play a large role in redirecting water to floodplains, lakes, and rivers. These overflow areas help urban atmospheres avoid the detrimental effects of heavy rainfall. These pumps only require an electrical source, so they can help you better prepare your city for major flooding.
Branches, leaves, and other debris can easily clog your city’s sewer system, so your city should regularly clean manholes. Additionally, your city should also encourage residents not to dump any trash or other hazardous materials into storm drains, as they can create blockages too.
Contractors should always request permission to build before they begin a new project. Your city should dissuade contractors from obstructing waterways and working on new projects in flood-prone areas. Be sure to review contractors’ plans carefully to ensure they construct buildings above flood levels as well.
