Late-Winter Storm Leaves Behind Flooding, Freeway Sinkhole

San Diego County received one of the heaviest soakings of the winter Wednesday from a storm that dropped 2 to 3 inches of rain at the coast and 5-plus inches in the mountains — precipitation that caused a large sinkhole on state Route 78 and numerous traffic accidents.

Caltrans said commuters began to report the sinkhole — described as “massive” by Vista Mayor John Franklin — in the middle of traffic lanes on the westbound side of the North County highway about 8:50 a.m.

Pursuing Independent Water Sources, San Diego Ignores One Beneath Its Feet

San Diego is not well endowed with many freshwater sources to support its growing population, so some water experts are perplexed the city’s ignoring a self-replenishing local groundwater source that, though small in size, is safe from the threat of natural disasters and reliably recharged by the San Diego River.

New Plan Aims to Fight Chronic Flooding During Rainstorms in Parts of San Diego

San Diego is trying to reduce chronic flooding in neighborhoods like Mission Valley, Sorrento Valley and the Tijuana River Valley with a comprehensive new plan to streamline the clearing of clogged stormwater channels across the city.

City Attorney Blasts SDSU Sale Plan; Says Ambitious Wastewater Plans in Danger

Friday, the San Diego City Council is set to review and give final approval to the historic deal to transfer the city’s Mission Valley land to San Diego State University. But late Friday, City Attorney Mara Elliott sent around another list of concerns this time focused on the city’s long-term plans to recycle wastewater. Elliott’s deputies wrote that city would face  “dire consequences in the future” if the deal goes forward as SDSU has sketched out in its final purchase and sales agreement.

If you have some quarantine time to kill, you can read the full memo, which includes background and explanation of the dilemma. The land is largely owned by the city in its Water Utility Fund and a large groundwater aquifer that the city could use to store water in the future.

The city plans to recycle water to such an extent that someday it will make up about a third of the city’s water source. It’s called the Pure Water project.

24,000 Pounds Of Trash Removed From San Diego River

More than 100 volunteers removed over 24,000 pounds of trash from the San Diego River on Oct. 26, the second largest watershed management area in San Diego County.

The cleanup came from a comprehensive survey of the lower 20.5 miles of the San Diego River to document trash locations. Over 180 trash sites were identified and mapped in the seven-mile section that volunteers cleaned, which stretches from Dog Beach to Mission Valley.

The San Diego River Park Foundation, who organized the cleanup, said the trash along the river is largely the result of homeless encampments, followed by stormwater debris. San Diego doesn’t treat stormwater, which leads to more pollution.
