About the Project

The City of Longmont awarded Frontier a contract to construct a 54 cubic yard diversion structure and a 24 cubic yard concrete flume with stilling basin on the Peck Ditch at Vance Brand Airport. The Work included constructing an active diversion of Peck ditch as the project was constructed during irrigation season. The project also included 120 LF of 36” RCP with Flared End sections, grouted riprap, ditch reconstruction, and Airport fencing. The project was constructed in an active ditch which required surface water diversions, dewatering for the duration of the project, temporary ditch crossings and management of stormwater events.
