City of Longmont Water Resources Planning

A small, welcoming city just north of Boulder, Colorado, the City of Longmont has relied on Schnabel’s water resources and supply planning services since 1982. We’ve conducted analyses of future raw water demands, evaluated the yield of the city’s raw water supplies, and compared future drought demands with raw water supplies to determine the adequacy of the city’s raw water supply system.

Our staff has evaluated alternatives for the city’s future raw water supplies and developed a raw water master plan with subsequent updates. We’ve also provided water rights litigation support for numerous city water rights applications, which include changes of use from irrigation to municipal use, changes of use from direct flow to storage, changes in place of storage for storage decrees, new storage appropriations, and a plan for augmentation. In total, we’ve helped Longmont obtain over 30 water court decrees for water rights, all but six without a water court trial. These cases have added many thousands of acre-feet of water supply yield to the city’s municipal use portfolio.

Additional civil engineering services we provided to the city include design and construction observation for numerous water storage and conveyance projects and a major river floodplain restoration project.
