Mainline Contracting made an outstanding effort to exceed compliance expectations for the installation of the drainage improvements, crossings and box culverts for the Back 9 holes at the Elkhorn Ridge Golf Course. The site compliance record at this time is outstanding and is clearly a result of good team effort. Mainline's crew that was assigned to our project were professional throughout the project and assured that the City's expectations were met and exceeded. In spite of numerous project challenges which included confined site conditions, groundwater/creek seepage, deep bore pits, large cobble to bore through and period of extreme cold weather, Mainline Contracting completed the project with quality workmanship, on time and on budget.
