A day before Hurricane Harvey inundated Houston, an obscure arm of the California Department of Water Resources delivered a report detailing the impact of the Central Valley deluge that surely will strike, and how best to prepare for it. We in this reclaimed city and in this re-engineered valley need to pay heed. Even in this past week of wilting heat, storm clouds are gathering. In issuing its flood protection plan, the Central Valley Flood Protection Board achieved a rare feat. It called for more taxes and more land use regulations, yet won the support of both farmers and environmentalists.
