The earth has a natural balance. The prairies, lakes, wetlands, deserts, mountains and oceans and rivers all work together to provide food and habitat for living things. Unfortunately, some places have gotten out of balance. Some areas are suffering terrible drought, and others have more rain and water than they can manage.
Building cities, driveways, parking lots, and roads changes the earth’s balance. What had been surfaces that were pervious, water drained through, are changed into impervious surfaces, that do not drain. Wetlands have gotten the shaft the past 200 years taking away the natural healing for our earth. Farmers have drained the wetlands to be used for agriculture and cities have drained and paved over these valuable places that naturally clean our water and provide homes for so much wildlife. When you build a city on a wetland you take away the natural ability to drain the area. You also destroy the dynamic life that lives there.
Houston sits on a wetland. Without any regulation parts of Houston were built on a wetlands. The concrete and asphalt took away the earth’s drainage capacity. The original wetland wants to flood, that’s what it is supposed to do, but all the hard paved surface has left only small patches of ground to drain the water and guess what? You have a flooded area.
How can Houston embrace their water? I hope that as Houston rebuilds from Hurricane Harvey they will work to maximize pervious areas, areas that drain, and limit the concrete and asphalt. It is impossible to plan for a 50 inch rain, but with some good science and skilled planning, some houses and many lives can be saved. Regulation and good minds are needed instead of a “Do what you want” attitude. I hope the people of Houston will try! It is so wasteful and expensive not to try to change the way they do things.
Areas need to be created that capture the water so it drains into the earth not into the rivers and streams. Run-off creates polluted water. The earth naturally cleans the water as it is absorbed by the earth. I hope Houston is willing to replace some concrete with renewed wetlands and rain gardens that will keep such destruction from happening again! Homeowners could be required to install pervious or permeable driveways or gardens that absorb water, or some area on their property that absorbs a percentage of water. See permeable driveways for ideas.
I heard one Houston homeowner on the radio, his house had flooded 3 times in the past 5 years. It is insane to keep doing the same thing over and over and expect a different result! Maybe we can all learn something from New Orleans. See below.
After fighting water New Orleans is starting to embrace their water problem with a new paradigm. I hope Houston can learn from them. Read about it at New Orleans.
Also, Mayors along the Mississippi River are embracing wetlands to improve water quality and this will help New Orleans and the Gulf of Mexico, also! Read about at wetlands.
Houston, it’s your turn! Wetlands can soak up lots of flood water. Can you do things differently this time around? Start listening to the scientists, engineers and environmentalists.
Houston helped put a man on the moon. Houston is the leader in the medical field. It could also begin to be a smart, resilient city if it puts its mind to it. That’s all it’s got to do. Read more at Houston.
Scientists, other experts and federal officials say Houston’s explosive growth is largely to blame. As millions have flocked to the metropolitan area in recent decades, local officials have largely snubbed stricter building regulations, allowing developers to pave over crucial acres of prairie land that once absorbed huge amounts of rainwater. That has led to an excess of
