A study by the Louisiana State University Economics & Policy Research Group says that not restoring coastal wetlands in Louisiana will cost the state $3.6 billion in lost infrastructure, homes and businesses over the next five decades and $7.6 billion in lost spending, wages and disruptions to the supply chain. The study did not include losses if a major hurricane hit the region, but it does note that the state's $50 billion restoration plan would create 7,800 to 10,500 jobs a year.

It was "Christmas in March" over the marshlands of Louisiana's Bayou Sauvage National Wildlife Refuge as National Guard helicopters dropped thousands of used Christmas trees. "The trees provide important habitat for waterfowl and fish, crab, crawfish and shrimp ... [and the measure] reverses shoreline erosion," said refuge manager Shelley Stiaes.

Stormwater Management
Stepped pools mute effects of stormwater runoff in Chesapeake Bay
The Chesapeake Bay is benefiting from the use of Step Pool Conveyance Systems by several Maryland jurisdictions to slow stormwater runoff before it reaches the bay. The systems incorporate stair-stepped pools with cobble riffles between that allow water to seep into the ground while filter media and vegetation capture pollutants.

Green infrastructure -- bioswales, permeable pavement, rain gardens and more -- can help reduce the overloading of sewer systems, and Washington, D.C.'s, Stormwater Retention Credit incentivizes property owners to use it. The program also "provides flexibility in complying with stormwater standards issued to D.C. through the US Environmental Protection Agency's MS4 (Municipal Separate Storm Sewer System) permit," this article states.

Maine city to begin 15 years of sewage, wastewater control
To comply with a federal mandate, the city of Bangor, Maine, needs to address the problem of raw sewage and stormwater spilling into the Penobscot River and Kenduskeag Stream. About $63 million worth of work will be required over 15 years, with the first project a $22 million installation of a 3.8 million-gallon wastewater storage tank this summer.

An approach to solving the Hantush equation
Eliminating the difficulties of solving the Hantush equation for transient flow was the goal of a study by Australia's Snowy Mountains Engineering. This paper explains how to do it and notes the approach also can be used to measure "feasibility of infiltrating water, attenuation zone, risk mitigation essential for decision-makers and planning regulators in terms of environmental effects and water use efficiency."
