October brings Los Angeles its first significant rainfall after months of drought, creating a perfect storm for plumbing disasters. When rain finally arrives, our storm drains—clogged with summer debris—often can’t handle the sudden deluge, leading to backups that threaten homes and businesses across the region.
Why October Rains Overwhelm LA’s Storm Systems
Los Angeles typically receives its first measurable rainfall in October, marking the beginning of our wet season. After six months of virtually no precipitation, storm drains accumulate leaves, trash, and sediment that create dangerous blockages. The city’s aging infrastructure, combined with hardened soil that can’t absorb water quickly, compounds the problem.
Properties in low-lying areas like Venice, parts of Long Beach, and the San Fernando Valley face the highest risk. Even neighborhoods that rarely flood can experience problems when October’s first storms arrive with intensity.
The Oil and Debris Factor
Summer’s accumulation creates a toxic mix:
- Motor oil from months of dry weather
- Decomposed leaves blocking drain grates
- Construction dust and sediment
- Accumulated trash and plastic debris
This combination not only blocks drainage but creates hazardous conditions when water finally flows. Properties near busy streets in downtown Los Angeles, Koreatown, and North Hollywood face particular challenges from automotive runoff.
Critical Pre-Rain Preparations
Inspect and Clear Property Drainage
Before October’s first rainfall, John’s Plumbing recommends comprehensive drainage inspection:
- Gutter Systems – Remove all debris and check downspout connections
- Area Drains – Clear grates and test flow rates
- French Drains – Ensure proper gravel coverage and flow
- Foundation Drainage – Verify water flows away from structures
Properties with previous flooding issues in Encino, Sherman Oaks, and hillside communities need extra attention.
Professional Storm Drain Services
Our hydro jetting services effectively clear storm drains before problems arise. High-pressure water removes years of buildup that standard cleaning can’t touch. Commercial properties with large parking areas particularly benefit from preventive hydro jetting.
Emergency Response Planning
Know Your Shut-Offs
October storms can quickly overwhelm systems. Every property owner should know:
- Main water shut-off location
- Sewer clean-out access points
- Electrical panel locations
- Emergency contact numbers
Backflow Prevention
Storm drain backups can force contaminated water into homes through:
- Floor drains in basements
- Low-lying fixtures
- Laundry room connections
- Garage drains
Installing backflow preventers protects your property from sewage contamination during heavy rains.
Commercial Property Vulnerabilities
Businesses face amplified October storm risks. Restaurants in Beverly Hills, retail centers in Burbank, and office buildings throughout LA must address:
- Grease trap overflow risks
- Parking lot drainage capacity
- Roof drain maintenance
- Underground parking protection
The Cost of Delayed Action
Storm drain backups cause:
- Structural foundation damage
- Contaminated interior spaces
- Inventory and equipment loss
- Business interruption claims
- Health code violations
