	The district recommends projects for the flight program each year at the request of [~~http~~://~~wwwi~~/~~design~~/~~default.htm~~ Design] by the last day of September. Projects recommended for mapping are those that a location study, if necessary, has been approved, or projects for which this will be completed in time to obtain the data during the flying season (approximately December 15 to April 15). Normally, projects that are in the design year of the approved STIP are considered, but other projects may be considered if conditions warrant.
