Mayor Robert Garcia on Monday is expected to announce what the city is billing as “significant improvements” to street sweeping schedules and routes, particularly in parking-impacted neighborhoods.

Long Beach Public Works has been working on street sweeping reforms, with the aim to cut early morning parking restrictions, as several residential neighborhoods in Long Beach — such as Willmore City, Alamitos Beach and Rose Park — prohibit car owners from parking curbside during early morning hours on street sweeping days.

Some streets are off-limits for parking as early as 4 to 8 a.m., leaving car owners to find a place to park the night before street sweepers roll through their neighborhood, or wake up to a ticket if their cars are parked curbside during prohibited hours. That, or they can get up before 4 a.m. and move their cars.

The City Council approved street-sweeping reforms when it adopted the fiscal year budget beginning Oct. 1.

Officials projected the cost at about $950,000 to eliminate pre-dawn parking restrictions, with the expense including new signs to alert drivers to the times they cannot park on a given street. Each sign costs an estimated $8 to produce and install, and there are roughly 118,000 such signs posted in Long Beach.

Garcia has called the parking reform the biggest in 30 years.
