Stop urban sprawl! Encourage brownfield development!  But don't put houses too close to freeways, ports or railyards!  Just, exactly, where does that leave us?  Helping us to navigate this no-man's land are three speakers with first-hand experience trying to weave a path through the thicket of urban development and air quality constraints.  We're pleased to welcome Larry Greene, Air Pollution Control Officer for the Sacramento Metropolitan Air Quality Management District; Jeffrey Dorso with the Diepenbrock Harrison law firm (who worked on the Sacramento Railyards project); and Brian Beveridge of the West Oakland Indicators Project.  We can promise a lively and stimulating discussion.
