Summary

Staff said tiles are in at the airport site except for the runway crossing and that the project includes 'farmable retention ponds' allowing farming through the pond area and controlled releases; local contractor Merrill's is hauling fill.

Staff reported work at the airport-area project is progressing, with most tiles in place except for the crossing under a runway. The design includes farmable retention ponds that will allow agricultural use while holding and releasing water at controlled rates. “Tiles all in except for crossing the runway,” the staff member said, noting heavy earthmoving by a local contractor and use of fill on nearby industrial park land.

Board members asked about depths and runway impacts; staff said the work will follow bid timelines and that runway crossings are likely a one- or two-day closure while the contractor completes work and reinstates surface materials. The board did not take further action at the meeting beyond noting the construction timeline.
