Yesterday, The Research Bureau published its annual survey of downtown office occupancy. While the occupancy rate decreased by less than one percent between 2009 and 2010, Table 1 of our report shows that the City has lost 10.6% of its downtown office space in the past five years and the amount of occupied space has decreased by almost 19% during the same time period. That means there are many fewer businesses downtown to pay the ever increasing tax burden than there were five years ago.
