 On-street parking rates were updated Monday for the second time this year. The goal is to curb demand and open up more parking spaces across the city. According to the Seattle Department of Transportation, the rates changed by 50 cents an hour in more than half of the city's busiest neighborhoods. Morning, afternoon or evening rates increased in 19 areas including Ballard, Capitol Hill, First Hill, Columbia City and Green Lake and decreased in four. The Seattle Times reports the city's most expensive parking areas are Fremont and Pike and Pine during afternoons and evenings at $6 an hour.
