Denver Water will be conducting a subsurface investigation program to support design of the Gross Reservoir Expansion project from June 2018 through October 2018. This work will take place in various locations on the south side of Gross Reservoir. These locations were chosen because they represent areas where knowledge of the subsurface conditions can inform work currently proposed on project features. Land disturbance from the investigation activities will be minimal and not cause major disruptions to traffic activities around Gross Reservoir.
The subsurface investigation program will include three types of activities which are described below.
