The Hood River City Council approved the purchase of a 12-by-44-foot mobile office for the municipal building department to be located at the City Public Works yard.  City Manager Steve Wheeler said with the department about to add a third employee, it needs more room than is currently available in the back of the Public Works’ office building.  Total cost of the building, including utilities and permitting, is $50,000.  In other business, Councilors approved a less than one percent average increase in garbage disposal rates.  Hood River Garbage requested the move, citing rising operational costs and disposal fees.
