Natural Cities, Healthy Waters

Runoff on our streets, pollution in our waters

Our waterways are special here in Texas, but unfortunately, they face increasing threats from flooding, drought and water pollution. A full two thirds of freshwater sites and nearly half of all our beaches were too polluted to safely swim in on at least one testing day in 2017. We deserve better, and luckily, nature-based infrastructure can help.  Here in Texas, we are advocating for the increased use of rain gardens, green roofs, wetlands and other nature-based infrastructure features which can prevent water pollution, mitigate flooding, ease drought, reduce urban heat and make our communities more beautiful.

As Texas grows, so does runoff pollution

Our State’s waterways, from Barton Creek to Galveston Bay, are the pride of Texas communities. They provide the water we drink, the rivers where we kayak, and the banks along which we play.

Unfortunately, runoff pollution threatens our water. The concrete jungle of development prevents rainwater from soaking into the ground, forcing it to run over roofs and roads, picking up oil, toxic chemicals, litter and animal waste. When this polluted water reaches our waterways it makes us sick and threatens the habitat of our wildlife.

The solution to runoff pollution is nature-based infrastructure, including rain gardens, green roofs, and the conservation of natural spaces. These techniques allow rainwater to soak into the ground, filtering out pollution, slowing floods, reducing erosion, and restoring our aquifers. Texas can use these features to protect our waterways. That’s why we’re calling on Texan communities to increase the use of nature-based infrastructure statewide: through innovative municipal policy, statewide research, and private development leadership. To protect our clean water, let’s use the best tools we have.

The Solution: Nature-based infrastructure

Nature-based Infrastructure imitates nature by allowing rainwater to slow down, and soak in to local soil. This prevents water pollution while mitigating floods, combating drought, and reducing urban heat. Common examples include rain gardens, green roofs, permeable surfaces and rainwater harvesting.

The benefits of nature based systems include:

  • Improving water quality. Stormwater systems can trap between 45 and 99 percent of solid pollutants.
  • Mitigating flooding. Nature-based systems can absorb between 50 and 90 percent of rainfall and have the potential to fully prevent flooding from less severe storms.
  • Preventing drought. Allowing rainfall to soak into local soils replenishes aquifers easing droughts later on.
  • Reducing urban heat. Green areas of cities absorb more heat reducing summer temperatures by 10-15 degrees.
  • Removing greenhouse gases from the atmosphere. Trees and green roofs can capture hundreds of pounds of carbon dioxide over their lifetimes.
  • Preventing toxic algae blooms. Filtering out pollutants decreases the amount of nutrient laden runoff that enters local waterways reducing the risk of toxic algae blooms.
  • Beautifying the landscape. Projects add greenspace to our communities, improving the quality of life.

Building support for the right policies, right now

By demonstrating to elected officials that the public wants nature-based infrastructure—and by working with green builders and suppliers, environmental engineers and landscape architects—we can get the right policies in place.

We have to act now, because we know that Texas’ cities are going to keep growing. That means that even more land will be covered with buildings and roads, even more rain will turn into runoff, and even more pollution will flow into our rivers, lakes and bays. But if we start using nature-based infrastructure across the state now, we can reduce the increase in runoff, and reduce the increase in runoff pollution.

What can you do?

Communities can use green methods in new public buildings and roads. They can also make it easier for businesses and residents to install green features by removing permitting barriers and providing financial incentives.

Call your city council member today and tell them that you want nature-based flood solutions in your community - by harnessing the power of nature-based infrastructure we can prevent flooding, reduce urban heat, midigate climate change, and so much more.

Luke Metzger, director of Environment Texas, a nonprofit dedicated to protecting Texas’ rivers, forest area, and wildlife, said the TWDB held a two-month comment period that ended with an April 29 hearing in Arlington, where there was overwhelming opposition to the project.

“There is really strong bipartisan opposition coming from Tea Party Republicans, the timber industry, local landowners, and the general public,” he said.

He estimated that “99.5 percent of the comments were opposed to the project.”

State Water Fund rules a big deal

As TWDB develops the rules and priorities for use of the new water funds, it's critical that they pursue a balanced solution that improves the efficiency of water use and leaves more water in our rivers and aquifers to support the ecosystems that depend on water.

Rules governing new water infrastructure fund are out | Luke Metzger

The Texas Water Development Board has released the proposed rules governing new state water infrastructure funds (know as SWIFT and SWIRFT) that will fund billions of dollars of water projects across the state. These rules are expected to be published by the Texas Register around July 10th which will start the formal public comment period, expected to end September 1st. For a copy of the draft rules, click here. This summer the Texas Water Development Board (TWDB) will hold three public hearings across Texas to receive feedback about these proposed rules. Ashley, our legal intern, addressed the TWDB last week and provided the first of many comments about the draft rules:

Over 16 Million Pounds of Toxic Chemicals Dumped into Texas’ Waterways

AUSTIN--Industrial facilities dumped more than 16 million pounds of toxic chemicals into Texas’ waterways, making Texas’ waterways the 2nd worst in the nation, according to a new report by Environment Texas Research and Policy Center.  The Wasting Our Waters report comes as the Environmental Protection Agency considers a new rule to restore Clean Water Act protections to thousands of waterways in Texas and across the nation.

Wasting Our Waterways

Industrial facilities continue to dump millions of pounds of toxic chemicals into America’s rivers, streams, lakes and ocean waters each year – threatening both the environment and human health. According to the U.S. Environmental Protection Agency (EPA), toxic discharges from industrial facilities are responsible for polluting more than 17,000 miles of rivers and about 210,000 acres of lakes, ponds and estuaries nationwide.
