Calibre provided full infrastructure expansion for this 2000-acre project.

 

For stormwater planning and management, Calibre’s unique and aesthetically-pleasing drainage design included 10 detention ponds with moisture treated clay liners and wetland edge treatments, as well as major drainage channel improvements, trickle channels, utilities, master water report, master sanitary analysis, emergency overflow paths, rip rap, storm inlets, open channels, roadway profiles, and water and sewer Master Plans.  Storm drainage modeling and analysis utilized HEC, SWMM, UDFCD software, and Pondpack.  Major pond design included 3 interconnecting ponds, each incorporating between 20-50 acre-feet of storage and non-jurisdictional permitting. Calibre performed an overall drainage conformance analysis.

 

Onsite and offsite infrastructure ranged from 8-36” pipes and required regional water quality, channels, irrigation ditches, PVRs, boring, water infrastructure (8-20” lines), tank analysis, and modeling.  The project also included a 24-inch casing of an 8-inch sanitary sewer interceptor crossing 350-feet of Northwest Parkway.

 

Roadway design included Preble Creek Parkway (2500 LF), 160th Avenue (3500 LF), and a traffic signals and analysis at Lowell and Sheridan and Lowell and Preble Creek Parkway.
