The City of Des Moines, WA is purchasing $124,191 worth of Bird-X bird deterrent balls to cover a 32,000-square-foot stormwater detention pond at the Des Moines Creek Business Park, after the Port of Seattle notified the city in 2023 that the pond was out of compliance with FAA wildlife hazard standards. FAA Advisory Circular 150/5200-33C requires physical barriers on stormwater ponds near public-use airports—such as Seattle-Tacoma International Airport—when standing water persists longer than 48 hours and poses a risk of attracting hazardous wildlife that could interact with aircraft. The City Council approved the purchase on November 21, 2024, with costs funded through the Surface Water Management Maintenance Fund.Open full document
