San Diego officials were informed repeatedly of the dangers of disease-carrying runoff from homeless encampments into area waterways, as far as a decade before the current hepatitis A crisis spurred action. Typical of the volumes of reports is a 2015 city plan for Mission Bay, which cited hepatitis research in setting priorities for officials regarding environmental quality. “The issues raised by transient encampments are socio-economic by nature,” the city Transportation and Storm Water report said. “Addressing the sources of homelessness requires coordination with law enforcement, social services, and the legal community. Therefore, it has been designated as an uncontrollable source.”

Gov. Jerry Brown’s bold $17 billion plan to build two gigantic 35-mile, 40-foot-wide tunnels under the Sacramento-San Joaquin Delta to make it easier to move water from Northern California to Southern California and to stabilize the state’s water distribution system always seemed like a tough sell. Critics were far more energized than supporters. Then last month, a huge new obstacle emerged. That’s when the Central Valley’s Westlands Water District — the nation’s biggest irrigation district — came out against the project. It had been expected to pay nearly a quarter of the $17 billion cost.

A Los Angeles city councilman is calling on the council and Mayor Eric Garcetti to oppose a crucial vote by a Southern California water board on a $17-billion project that would be funded in part by Los Angeles ratepayers. Councilman Paul Koretz introduced a resolution Friday that asks the city and Garcetti to formally object to a vote by the board of the Metropolitan Water District of Southern California on the project, known as California WaterFix. The 38-member board is scheduled to vote Tuesday on whether to commit $4.3 billion in MWD funds to the project.

A new group known as the Clear the Air coalition has risen up to discourage the city of San Diego from taking on San Diego Gas & Electric. The city wants 100 percent of electricity sold within city limits to come from renewable sources by 2035. SDG&E argues that it’s too risky and too expensive to abandon natural gas-fired power right now. So, the city is thinking about buying energy for its 1.4 million residents by becoming a community choice aggregator, or CCA. The City Council could vote on the switch in the next several months.
