The volume of new supply at community and neighborhood shopping centers in 2010 was only 40 percent of projected deliveries, leading to a slower rise in vacancy rate than initially forecast.

More than 7 million square feet of retail projects slated for completion in 2010 were delayed or canceled. This pullback in construction led to only 4.1 million square feet of retail space coming on line, the lowest figure for annual deliveries in the 30-year history of Reis.
