SUBJECT: Summary of meeting regarding Port'ssubmittalof requested information 1.

To that end, they submitted draft-revised documents summarizingthe impact to functionsand consequences. We will meet again on 26 April 2001 to discussto adequacy of the revisions. The next meeting after that was scheduled for 2 May 2001. 2. We then discussed their approach to cumulative impacts. They purchased aerial photos from the 1930's of the area prior to construction of the airport. They also found copies of the soil survey for the area prior to development. Based on their interpretation of the photos, cross referenced with the mapped hydric soils with a safety factor based on the percentage of hydric soil inclusions, they will estimate the amount and types of impacts as a result of previous work of the airport.
