The Hood River city public works department says crews will perform night-time street-sweeping operations starting this coming Sunday night and continuing until Thursday night.  Sweeping will take place from 10 p.m. to 6 a.m. each night.  City officials say that in preparation for the city-wide sweeping, residents will be allowed to sweep their sidewalk debris into the street in advance of this schedule.  That’s normally treated as a storm-water violation and is against municipal code.  Residents are asked to park off-street when possible during the street-sweeping schedule, particularly on State Street between 6^th and 9^th streets on Sunday and Monday nights in order to completely clean the north and south sides of State Street.
