South of Mather Airport is a grassy field popular with nature lovers and school field trips, particularly in the spring when the vernal pools are in bloom.

Sometimes, a building’s security needs can pop up unexpectedly during the design process.

How many farmers can say they spent their childhood bowling at Camp David or playing football with the Kennedy clan on the White House lawn? It’s the path Craig McNamara, 60, has taken from Washington, D.C., to his 450-acre organic walnut farm, and, at times, it was torturous.

Bruce Stephens might be on to something. And if his estimates — and the optimism and faith of dozens of investors — prove accurate, his wine bottle washing company could provide a hefty return on investment, dozens of Stockton jobs and low-cost wine bottles for environment and budget-â?¨conscious wineries.

Five years ago, Truckee’s Martis Camp fell out of the hands of land planners and golf-course designers and into the hands of lawyers.

This is the final story in a four-part series on water. This month, we’ll wrap up by examining upcoming issues in 2010. Past installments of this series have explored water issues ranging from storage, conservation and desalination, to impacts of a peripheral canal on the Sacramento-San Joaquin Delta.

In 2008, Bill Koster had his best year in three and a half decades of farming. Commodity prices hit record highs, his expenses were low and water allocation was enough to yield a decent crop, even though it was less than half his contracted amount.

On Twitchell Island, near the Delta town of Isleton, tules covering 15 acres grow twice as tall as the average man. A gravel road separates the wetlands from a cornfield, sunken 25 feet at its lowest point. Every year, the wetlands’ soil rises a few inches, while the cornfield sinks. The discovery that tules increase land elevation in the Sacramento-San Joaquin Delta is fueling a joint experiment conducted by the state Department of Water Resources and the U.S. Geological Survey, along with UC Davis researchers, other universities and private consultants.

If Sir Isaac Newton were around today to assess California’s interest in seawater desalination, he would likely reference his own third law of motion, which in simple terms states that for every action there is an equal and opposite reaction. In short, as our water supply dwindles, the desire to glean freshwater from salty oceans and brackish groundwater is growing.

California’s cities and counties are facing the formidable challenge of determining how they’ll tackle regulations outlined in the state’s greenhouse gas legislation.
