Cobblestone Ranch Tank 18
Due to expanded development in the Cobblestone Ranch area, a 2-million-gallon water tank, appropriate water transmission lines and accompanying fire hydrants is under construction currently. Tank 18 will be located off of Antelope Place and Pleasant View Drive on Town property adjacent to Douglas County and private property. A water tank is an essential piece of infrastructure to provide sufficient water pressure and fire protection to properties within the distribution area.
As Town character is a cornerstone of our development, the design for Tank 18 is to blend with the surrounding terrain. It will be partially buried with approximately zero to 25 feet of exposure. Most of this exposure is expected to be from a domed roof on the structure.

A 16-inch transmission pipeline will be constructed to supply water to the tank. The transmission pipeline that will follow the entire length of Pleasant View Drive will connect Tank 18 to the water main line currently along Castle Oaks Drive. Approximately 21 fire hydrants will be connected along the transmission pipeline, providing fire protection to both the Town and County areas.
Upon completion of the water infrastructure, the developer is expected to pave a portion of Pleasant View Drive from the northeast connection to Castle Oaks towards Antelope Place as the neighborhood is built, and Castle Rock Water will resurface the disturbed portion of Pleasant View Drive west of Antelope Place to its current composition.

Service disruptions & traffic detours
Construction traffic for the tank project will continue along Pleasant View Drive and Antelope Place. Because construction access to the site is limited to gravel roadways, there will continue to be a temporary increase in roadway dust generated from the temporary increase in traffic.
No water service disruptions are anticipated.
Construction activity will be restricted to weekdays from 7 am to 6 pm, although work may also occur outside those times as approved by the Town to accommodate special conditions.
Temporary road closure along Pleasant View will be required for the transmission pipeline construction. Detour signs will be posted and the contractor will contact the local residents about the location of the road closure. Local residents will have access to their properties at all times.
Construction began in July 2022. Construction of the concrete tank structure was completed in November 2022. The contractor will be completing tank appurtenance installation and site utility and grading work throughout the winter and spring months. Project completion and tank site restoration are anticipated in spring 2023.
On August 16, 2022, Town Council approved a contract with Reynolds Construction for the Tank 18 Blue Zone Transmission Main in the amount of $4,081,473. The contractor has started the construction of the pipeline within the Town boundary. The Town is working with the County for the traffic control permits within the County portion of the project. Work within the County portion is anticipated to begin in late December or January. The project will be completed in spring 2023.
