Worcestershire chief executive David Leatherdale tells BBC Hereford & Worcester that weather delays in 2013 could have cost the county up to half a million pounds.
The county were thwarted by five winter floods in their mission to get their new redevelopment at the New Road open in time for the visit of the Australian tour team and their five FLt20 home matches in late June and July.
"Just in lost ticket sales in not having the extra seating available for the Australia game, that cost us £80,000-100,000," he said.
"Not having three floors and extra bars available for corporate guests cost another £100-150,000. It adds up quickly. That's a quarter of a million. Then you add on the Twenty20 as well. All budgeted revenue that we could not do anything about."
