PACIFIC PALISADES, CA — Tuesday, August 19, 2025 — Crews from United Storm Water, Inc. were at work along Temescal Canyon this week, installing a newly designed stainless steel storm drain gate built to improve both safety and durability. The installation featured the company’s Wing-Gate™ automatic retractable curb inlet screen cover (ARS), an advanced system designed to block trash and debris from entering storm drains during dry conditions while automatically opening under heavy water flow to prevent flooding. Unlike previous bolted-on models, the new gates were welded directly into place — a security measure taken after thefts of earlier stainless steel units, which had been targeted for scrap resale. Technicians custom-fitted and welded the Wing-Gate™ covers directly onto the curb inlets. The stainless steel screens are perforated with three-quarter-inch holes, ensuring pollutants are trapped while water flow continues. Each unit includes a calibrated spring-activated mechanism that allows the gate to open laterally under pressure from stormwater and debris, then automatically return to a closed position as rainfall subsides. The enhanced design reflects a broader effort in storm water management to balance flood prevention with environmental protection. By intercepting litter and debris before they reach the ocean, the Wing-Gate™ helps safeguard marine life, beaches, and public health. Santa Monica Closeup will continue monitoring regional infrastructure improvements as communities adapt to more frequent storm events and the growing challenge of waterway pollution.
According to authorities, the operation followed a wave of public complaints and reports of serious accidents involving high-speed e-bikes in the beach area. Sur-Ron-style electric motorcycles, while sometimes mistaken for standard e-bikes, do not meet California’s legal definition of a street-legal electric bicycle. These off-road vehicles often exceed power outputs of 3,000 watts and can reach speeds above 40 miles per hour. In most cases, they also lack operable pedals, disqualifying them from being registered as Class 1, 2, or 3 e-bikes under state law.
In California, legal electric bicycles must be equipped with functioning pedals and powered by an electric motor of no more than 750 watts. Class 1 and Class 2 e-bikes are limited to speeds of 20 miles per hour, with Class 2 models allowing throttle-assisted propulsion. Class 3 e-bikes permit pedal-assisted speeds up to 28 miles per hour and require helmets for riders under 18, along with other safety provisions. Sur-Ron models, by contrast, are designed exclusively for off-highway use and fall under the category of electric dirt bikes. They are neither eligible for registration as street vehicles nor protected by bicycle exemptions, making their operation on public roads, bike paths, or sidewalks illegal.
The seized vehicles can be recovered by their owners upon proof of ownership and payment of towing and storage fees. Police say enforcement efforts will continue as part of a broader push to address unsafe and unregulated e-bike use on the beach and in other public areas.
