When I walk around my neighborhood, it’s clear that a new level of commitment to water-use efficiency has taken hold at the grassroots level. About half the homes around me have upgraded from conventional turf-based landscapes to attractive, low-water landscapes that are more appropriate for the climate of San Diego County. I see the same phenomenon across the county; residents and businesses are making the most of our water supplies like never before. In fact, we collectively use nearly 40 percent less potable water per capita today than we did in 1990.
