DOUGLAS M. JOHNSTON is chair of the Department of Community and Regional Planning and of the Department of Landscape Architecture at ISU wrote a great article about the Iowa floods*
During and after any catastrophe, many will review the events and ask: Why did it happen and what can be done to prevent it? The ongoing flooding in Iowa is no exception.
…….we often fail to remember is that water flows downhill. It comes from somewhere, and it goes somewhere. Anything we do that affects the flow of water will have an impact further downstream. Prairie and forest are good at capturing rainfall. Tile-drained farm fields, roofs, roads, and parking lots are less so. With fewer wetlands, prairies and forest to slow runoff or prevent it, the same rain event will send more water downstream faster.

San Franciso Chronicle has published a practical artile on permeable pavement – sort of a Sustainable Landscape Design 101
Does your driveway look like a patchwork quilt, with raised and sunken surfaces; chipped, off-color mortar stuffed into jagged cracks; and a generation’s worth of oil, paint and mold stains? Has the time come to replace it? Or, if your driveway is fine, is this the year to install the new patio you’ve been dreaming of, or some garden walkways?
Whether you’re replacing your existing driveway, patio and walks or installing new ones, you have an opportunity to turn them into water management and conservation features by building them so water can drain through them – in landscaping terms, making them “permeable hardscape.”

Another major “green roof” project is set to move forward atop a high-profile building in downtown Minneapolis.
City officials are putting together construction documents for a green roof over Target Center, even as the city – with help from a project team led by RSP Architects – continues the job of planting 40 varieties of mostly native plants on a portion of Minneapolis City Hall.
The Target Center project was first reported by Finance and Commerce in March 2007.
By putting vegetation on top of the 18-year-old city-owned arena, the city hopes to protect the membrane and extend the roof’s life. Green roofs typically last 40 to 50 years, compared to 20 to 25 years for a conventional roof, Guild said.

The European Commission last week hosted a high-level conference on the relationship between soil and climate change, and the role of soil management in climate change mitigation and adaptation. Organic matter plays a fundamental role supporting soil fertility, retaining water, sustaining biodiversity and regulating the global carbon cycle. But organic matter is in decline, and the conference heard how large amounts of carbon have been lost to the atmosphere in recent years. The Commission states it is convinced of the need to act at EU level to protect soil
