Montrose Landfill Phasing Plans

Montrose Landfill Phasing Plans

HAL provided planning for Waste Management at their Montrose, Colorado, municipal landfill that included a phasing plan through the year 2039. HAL used AutoCAD Civil 3D with an existing topographic surface to define the ultimate closure surface and determine construction phases in 5- to 10-year increments. A phased drainage plan was also defined. Waste Management used the plans to prioritize capital improvements and allocate resources to future budgets.
