This workshop led by Stuart S. Schwartz introduces "suburban subsoiling" - the combination of subsoiling (or deep soil ripping) with aggressive organic compost amendment, as a sustainable landscaping practice to restore hydrologic function to the Bay's pervious landscapes. This practice holds great potential to turn every yard, lawn, and transportation median into a high performing infiltration structure. Simple field protocols to evaluate the compaction and infiltration condition of yards, lawns, and pervious land uses will be demonstrated and introduced as part of a grass roots effort to characterize the hydrologic performance of the Bay's urban landscapes.

A senior research scientist at the Center for Urban Environmental Research and Education (CUERE) at the University of Maryland Baltimore County, Stuart Schwartz's current research includes hydrologic design and performance of pervious concrete, sustainable water resources management, and stormwater performance criteria for environmental site design. He has served as director of the Center for Environmental Science, Technology, and Policy at Cleveland State University; associate director of the Water Resources Research Institute of the University of North Carolina; and director of the Section for Cooperative Water Supply Operations on the Potomac at the Interstate Commission on the Potomac River Basin.
