Background: The Vernon Street Town Square’s (VSTS) Spray Ground was constructed in 2013. The VSTS is the“front yard” of the City of Roseville’s Civic Center which includes City administration offices and the City Council Chambers. The VSTS is enjoyed by staff and residents. This public space serves as a venue for special events throughout the year attracting residents and visitors to spend time in our downtown area. The Spray Ground is a highlighted feature of the VSTS. The Spray Ground offers a place for children of all ages from May through October each year. During this timeframe, the Spray Ground often requires closure due to the unreliability of the mechanical system, mainly failures related to the automatic valves and controller. To further the issue, we are unable to isolate the valves to close off portions of the system to allow for repair work to be performed. As is, the entire system must be shut off to replace one component. The Spray Ground is a recirculating water system that operates similarly to a pool. The fountain features flush deck sprays that drain into a shallow below-grade pool and feeds into an underground balance sump. Underground piping connects the drain sump to an adjacent underground vault that houses the Spray Ground mechanical equipment. Underground piping connects the mechanical equipment to the chemical storage and feed equipment that is housed across the plaza, approximately 150 feet away, near the restrooms. The Spray Ground water is then pumped back under the plaza to the fountain. The original system was designed to be run by a controller that allows for the sequencing of spray jets for different display patterns. The goals of this renovation include: • Relocating the Spray Ground controller from the pump vault below ground to the restroom/trash compactor area above ground. Two empty 1” conduits have been previously installed from the vault to the structure. • Re-designing the Spray Ground surface with a stable surface material that doesn’t separate or bounce. The finished surface is currently a series of granite tiles set on an elevated steel grid suspended over 3 foot deep “pool”. The tiles move and leave gaps between one another. This pool drains into the underground vault and through the pump system. • Replace the spray nozzles and controller to achieve a “dancing waters” system. • Upgrade the rules sign associated with the Spray Ground and as required by the Health Department.
