Local environmental issues: watersheds, beaches, wetlands and waste

Almost every environmental problem is settled locally. Water quality is regulated in California by the State Water Resources Control Board through nine Regional Water Quality Control Boards, each drawn around a watershed rather than a county line — which is why a pollution problem is usually described by the river or bay it drains into, not by the town it started in.

Beach water is monitored on a fixed schedule. Under California's AB 411 rules, beaches with high visitor numbers are tested weekly for bacterial indicators during the busy season, and postings or closures follow when counts exceed the health standard. Most of those exceedances follow rainfall, because urban stormwater runs off roofs, roads and driveways into storm drains and reaches the ocean untreated — a storm drain is not a sewer, and nothing that enters one is cleaned on the way out.

Wetland restoration is the other long game. The Bolsa Chica wetlands in Orange County are among the largest restored coastal wetlands in Southern California, reconnected to tidal flow in 2006 after decades of oil production and development pressure. Restored wetlands do real work: they filter runoff, buffer storm surge, and provide nursery habitat for fish and nesting sites for shorebirds.

Things that genuinely help locally

  • Stay off the sand for 72 hours after heavy rain — that is the standard public-health advisory window for urban beaches, and it exists because of runoff.
  • Redeem your CRV containers — California's deposit is 5¢ on beverage containers under 24 oz and 10¢ at 24 oz and above.
  • Keep the storm drain clean — fertiliser, motor oil, paint and pet waste on a driveway are all one rainfall away from the ocean.
  • Plant for the local climate — native and drought-adapted planting cuts both irrigation demand and the runoff that carries garden chemicals downstream.
