American cities seem to be the hub for climate change strategy these days. For many state governments, the prospect of implementing incremental changes to how they produce, sell and benefit from power is a fight-or-die issue that will ultimately be born out in the Supreme Court. But for many of their cities, like Seattle, San Francisco, New York and even Charleston, West Virginia — the heart of a coordinated challenge to the Environmental Protection Agency — change is, well, just common sense.

The nine major watersheds in San Diego County had unusually low water quality in 2015 for the second year in a row, according to an annual report released Tuesday by an environmental organization.

The continuing drought may be worsening inland water quality, while runoff pollution remains a serious problem, the San Diego Coastkeeper report says. “Our inland waters empty to the ocean,” said Meredith Meyers, the group’s laboratory coordinator. “These inland water quality problems directly impact the water quality of our beaches, too, making them less safe to swim and fish.”

Cadiz Inc. won a decisive courtroom victory Tuesday for its plans to transfer ancient groundwater in a remote part of San Bernardino County’s Mojave Desert to parts of Orange County and other locations.

California’s Fourth District Court of Appeal in Santa Ana upheld six lower court decisions dealing with various governmental approvals and environmental reviews of the controversial water project.

On the same day that Gov. Jerry Brown sought to make water conservation a way of life for Californians by permanently banning some wasteful practices, regulators in Sacramento prepared to significantly ease the current drought restrictions for urban residents and businesses.

Brown issued an executive order Monday that places an indefinite moratorium on hosing off sidewalks and driveways, as well as washing cars with hoses that don’t have a shut-off valve. All fountains and decorative water features must use recirculated water, and watering lawns is restricted for 48 hours after a rainfall.

San Diego County residents will need to permanently curtail their water use under an order issued Monday by Gov. Jerry Brown that bans activities such as hosing off sidewalks and requires urban suppliers to continuing producing monthly reports on water-reduction efforts.

The order calls for long-term implementation of temporary water conservation measures put in place to combat the ongoing statewide drought, with Brown pointing to some parts of the state that are still dealing with dry conditions and the likelihood of continued water shortages.
