Each day the site will list areas where parking tickets won't be handed out, such as when street-sweeping services have been canceled and residents won't have to move their cars.
Information about street sweeping in each council district is also listed in a PDF format on the site.

Such parking enforcement data wasn't readily available to residents until now, officials said.
The site is about "focusing on customer service and delivering core services more efficiently and effectively," Garcetti said in a statement.
Noticeable kinks were evident on Tuesday afternoon, however. The site failed to recognize numerous locations.
Mayoral spokeswoman Vicki Curry referred to the new website as a "beta site" and said more changes are expected. She also acknowledged the city has "a long way to go" before offering a more comprehensive site.
Despite its bare bones appearance, officials contend the site will allow residents to more easily fight street-sweeping tickets issued in error. About 5 percent of the streets marked for sweeping each day are never cleaned because of scheduling or staffing issues.
The city doesn't ticket cars on uncleaned streets on those days, but "obviously something could slip through the cracks," said Transportation Department spokesman Bruce Gillman. He praised the site as another customer-friendly tool for residents.
