Agricultural Prices and Indexes are available through the National Agricultural Statistics Service Home Page.  The direct link is to Agricultural Prices.  Historical data is easily assessable from http://quickstats.nass.usda.gov/.

The BEA Regional Projections, 1969 to 2045 spreadsheet (xls, 3.88 MB) (formerly OBERS) projections are available.  This spreadsheet includes employment, earnings, and gross sector production by industrial sector, by state and MSA annually 1969 to 1993, plus forecasts through 2045. Some items, like content (not buildings) flood damages, can include future increases based on these GDP type projections. BEA has since discontinued their Regional Projections Program: Discontinuation of the Regional Projections Program (PDF,660 KB).  But many older NRCS projects used them. 

Instructions on the use of these regional projections for estimating future flood damages are included in Principles and Guidelines for Water Resource Projects,(PDF, 1.22MB) section 2.4.11(c), Pages 36-37 and page 47.
