Record flooding in parts of the Midwest in March caused immense damage to agriculture. Water is still standing in fields where failed river levees have not yet been repaired. For some farmers and ranchers, already facing low commodity prices, tariffs and taxes, it’s a compounded level of stress driving record numbers to seek professional help.

A Los Angeles Times analysis

Beavers take advantage of ponds brimming with water, nearby dirt roads show little evidence of being recently inundated. In the greater Houston area, though, the staggering increase of impervious surfaces - roads, sidewalks, parking lots, anything covered with asphalt and concrete - has exacerbated the effects of flooding as development in the region has exploded. Things are further complicated in flat-as-a-pancake Houston, where much of the soil is heavily compacted and acts like pavement anyway, sending sheets of stormwater to the nearest low-lying area. A recent analysis of federal satellite data by the Houston Advanced Research Council for the Houston Chronicle shows that 337,000 acres of 1.1 million acres in Harris County were covered by impervious surfaces in 2011, the most recent year of data. That kind of development comes with a price, namely the loss of the region's natural landscape, including wetlands, prairies, coastal marshlands and forests, and thereby a greater risk of flooding. While many Houston-area homeowners blame inadequate stormwater mitigation rules for their flooding woes, city and county officials deny that but concede that it's difficult to untangle the effects of new development, flood control projects and climate change when trying to determine the culprit for the region's worsening flood problem. People love water features, said Trey Reichert, vice president and general manager of Riverstone for Johnson Development Corp. There's something very calming. Larry Dunbar was a consultant hired by Fort Bend in the early 80's to help draft the first set of detention pond requirements. [...] most counties were solely relying on drainage systems to combat runoff. The group, Residents Against Flooding, cited the 2007 widening of Bunker Hill Road north of I-10 and the elevation of nearby commercial properties, among other projects, alleging they funneled water into surrounding neighborhoods. The residents' group claims the defendants promised to build five detention ponds to alleviate flooding but only came through with one. A Texas A&M University study in 2011 found that clustered high-density development - the kind you see in the concrete-laden urban core of Houston - typically experience less in flood damages than sprawling low-density developments that have become hallmarks of Houston's suburbs. The 232 unit-complex, subsidized for low-income residents, was built in the floodway of Green's Bayou and is being rebuilt in the same spot in the city's Greenspoint neighborhood in north Houston near Bush Intercontinental Airport. Given the challenges associated with detention ponds and other structural solutions to Houston's regional flooding problems, officials are getting pressure to consider "greener" solutions. The Bayou Land Conservancy, which protects more than 2,000 acres in Montgomery County, wants to make sure development stays out of the floodplain and turn that land into a community amenity, whether a butterfly garden, wildlife habitat or a place for recreation. Stephanie Prosser, the conservancy's interim executive director, points to the Spring Creek Greenway, a forested corridor that spans the divide between Harris and Montgomery counties, as a good example of an environmentally friendly project. A study conducted by the Harris County Flood Control District two years ago looked at how water flows from the Cypress Creek watershed to Addicks and Barker reservoirs and shows that sage grass - grass with a similar root structure of the prairie grass found in that area - does a pretty good job of absorbing water given the poor absorption of the area's clay soil. In Pattison, smack dab in the middle of the Katy Prairie, more than 23 inches of rain fell during a 14-hour period on April 17 and 18, the highest amount ever recorded in the county for an historic rainfall event. [...] they'll need new roads to get there.
