However, because data provided by FEMA contained numerous discrepancies, we could not account for all the expenses incurred at these sites. In particular, although we were able to determine the number of trailer pads at each site, FEMA could not provide us with an accurate trailer count. For purposes of our analysis, we assumed that the parks were operating with a trailer on each available pad. We also did not have accurate information about utility payments FEMA made for these specific sites and the trailers. As with the trailers at the private sites, our estimate is likely understated because we did not have access to the trailer and site maintenance payments made to the original four contractors and because we could not calculate MD phase-in and deactivation expenses. In addition, we do not know how much it will cost to return the group sites to their original condition, as required by the terms of the group site leases.
