U.S. dams group honors Kansas dam

The U.S. Society on Dams presented its 2009 Excellence in the Constructed Project award to Lake Lenexa Dam and Spillway in Kansas.

The city of Lenexa, a suburb of Kansas City, Mo., owns Lake Lenexa and associated park land. It included the dam and spillway in a “rain to recreation” program that uses stormwater to create recreational opportunities.

The $23 million project benefits area residents by providing flood control, improved water quality through construction of wetlands, natural stream preservation and restoration, stormwater management through incorporation of porous pavement and “rain gardens,” and recreational and educational opportunities.

The dam includes 8,000 cubic yards of steel-reinforced concrete. The 800-foot-long, 50-foot-tall civil structure has 700 acre-feet of stormwater storage. It creates a 35-acre lake within nearly 350 acres of park land for fishing, nature education, and non-motorized boating. The facilities feature trails, picnic areas, and boardwalks.

Lenexa Mayor Mike Boehm and engineering, consulting, and construction company Black &Veatch of Overland Park, Kan., announced the award May 12. Black &Veatch provided study, public outreach, design, and construction management services. The award was presented April 22 at USSD’s annual conference, in Nashville, Tenn.

The USSD 2009 Excellence in the Constructed Project Award recognizes contributions to the dam community and to society through the construction, remediation, or removal of a dam or water resources structure. The award honors those who meet the challenges of aging infrastructure in an era of limited financial resources and increasing environmental awareness.
