• County: Statewide
• Title: Flood Disaster and Mitigation Plan and Standard Operating Procedures
• Date: 4/26/2007
• Prepared For: CWCB
• Prepared By: Urban Drainage
• Floodplain - Doc Type: Correspondence

Basic District Goals
The District is not directly involved in any warning, evacuation or flood fighting activities.
Immediately prior to and during a flood event the District goals are to document the flood event (with
pictures) and to provide assistance to local governments to the extent possible as requested.
Immediately following a flood the District goals are continued documentation; evaluation of how
District-funded plans, construction, etc. worked; and providing assistance to local governments.
Details are given in Sections 3.0, 4.0 and 5.0 ofthe FDMP.
Outside Assistance
The following agencies and consultants can be contacted for assistance in the areas described.
1. Colorado Water Conservation Board (CWCB) - Coordinate aerial photography (black and
white and infrared) with CWCB. Either the District or CWCB should contact the
Colorado Division of Emergency Management (Colorado DEM) to inform them of the
flooding situation and of any aerial photography plans, in order to prevent duplication of
effort. Specifically request Colorado DEM to determine whether or not other agencies
are also considering aerial photography, and to report their findings back prior to
initiating the CWCB/District photography.
2. Leonard Rice Engineers (LRE) - LRE can provide people to take pictures during and
immediately following a flood. They also can provide on-the-ground documentation of
flood outlines and high water marks.
3. U.S. Geological Survey (USGS) - USGS can be requested to obtain high water and cross-
section data and develop flood discharge estimates, although we do not have a formalized
commitment from them. Use LRE first.
Actions To Be Taken
Following are check lists of actions to be taken, or at least considered, for various stages of a
flood situation. The engineer in charge must exercise his best judgment as to which actions to
actually take, based on the situation. For example, intersection flooding would not require
notification of the CWCB. When notifications or field operations are necessary, keep a log noting
who was contacted, at what time, and any follow-up actions taken (see "District Flood Incident
Action Log" in the appendix of this SOP).
1. DURING WORKING HOURS
A. Message 1 (Nuisance Flood Advisory) or Message 2 (Flash Flood Watch)
1. Advise everyone in the office of the situation.
2. Attempt to locate other staff members who are out of the office and advise them.
3. Staff members out of the office will keep the office advised oftheir whereabouts at
all times.
4. Check for available digital and video cameras.
