Boise Airport expands a storm water retention pond
Teya Vitu//September 14, 2018
Boise Airport has been working since Aug. 20 on expanding the storm water retention pond next to Firehawk Helicopters along Wright Street.
The $148,000 work will expand the 15,000-cubic-yard retention pond to 21,000 cubic yards to accommodate unusual storm events with excessive precipitation, airport spokesman Sean Briggs said.
The massive winter 2016-17 snowfall filled this pond at the northwest side of the airfield to capacity, encouraging the airport to expand it, even though overflowing water flows west to another retention pond and infiltrates into the ground, Briggs said.
The expansion also upgrades a natural spillway to a concrete spillway.
Boise Airport has eight storm water retention ponds.
The general contractor is Western Idaho Construction and Landscape. Completion is expected in October.
