City of East Grand Rapids issued the following announcement on May 20.
With Memorial Day just around the corner, please keep in mind that the outdoor storage of boats, trailers and RVs is allowed for up to 72 hours on streets and driveways. Otherwise, they must be stored indoors, or in a rear yard only, and then they must be reasonably shielded from view. Not all properties are capable of accommodating such storage so you might have to seek offsite storage for your recreational unit.
