Look, I just read something from CalMatters Housing about how San Diego is bracing for what could be a pretty significant winter weather season, and it got me thinking about how infrastructure challenges ripple through real estate markets everywhere, including here in the Bay Area.
According to CalMatiers Housing, San Diego is dealing with a "super El Niño" pattern, which historically tends to bring heavier winter storms to Southern California. The thing is, the relationship between ocean temperatures and actual rainfall has gotten less predictable in recent years, so nobody can say for certain whether they're looking at extreme flooding, dry conditions, or something in between. What everyone does agree on is that when atmospheric rivers do hit, they can drop significant rainfall, and San Diego's got the geography to make that dangerous. The reporting notes that the city established a special working group across all departments to prepare for whatever comes their way.
The real challenge in San Diego, according to the reporting, is that their stormwater systems are aging and their dams average about a century old. Just last January, Chollas Creek flooded over a thousand homes in one neighborhood, and while experts called it a rare event, residents argued the damage was made worse by years of deferred maintenance on the city's storm channels. The city lists over three billion dollars in needed stormwater upgrades, though it's unclear how they plan to fund those improvements beyond the eight hundred million they say they've already invested.
CalMatters Housing also reported that San Diego's dam situation is particularly precarious. One dam at Lake Hodges is rated unsatisfactory and poses extreme downstream hazard potential, and rebuilding it completely would cost somewhere between six hundred and seventy million dollars. A plan to replace it by twenty twenty-nine fell apart when costs ballooned past what the county water authority was willing to share, so the city is moving forward on its own.
What I'm seeing locally here in the Bay Area and throughout the East Bay is that aging infrastructure becomes a real headwind for property values and development when people start paying attention to these risks. San Diego's situation underscores something we deal with too, which is how deferred maintenance on public systems eventually becomes a property issue that buyers and sellers have to contend with. Fremont sellers especially understand how flood risk and dam safety concerns can affect marketability and insurance costs.
