For residences and businesses along Ralston Creek, Leyden Creek, Van Bibber Creek and Moon Gulch, a flash flood warning would not likely provide enough lead-time to safely effect damage prevention measures such as sandbagging. Emergency property protection would probably be limited to turning off main gas and electricity connections. The following pages provide a brief description of each of the three required elements listed above relative to this flood warning plan for the Ralston Creek drainage basin. JCC is the primary communications link between HMS, NWS and other flood warning plan participants. Communication arrangements defined to insure adequate communications between all parties at all times.
Primary communications are by telephone.
Amateur radio operators may be contacted to provide backup communications. Standard messages used by HMS to provide information to JCC for relay to affected jurisdictions. Officials from Arvada, Jefferson County and volunteer fire districts who receive all critical weather and flood information and respond according to their respective internal procedures. Internal procedures and operating guidelines which are maintained, practiced and routinely updated by each participating local government agency, forecast service and support organization. Satellite imagery display equipment located at NWS and HMS enabling meteorologists to see approaching weather systems and estimate local arrival times.
