Colorado Association of Stormwater and Floodplain Managers

Visit the CASFM Website at for complete and current information about our organization.

CASFM is an organization of professionals whose members are involved in floodplain management, flood hazard mitigation, stormwater management, the National Flood Insurance Program, and flood preparedness, warning, and recovery. CASFM has grown to be a respected voice in floodplain management practice and policy in Colorado. CASFM represent the interests of flood hazard specialists from local and state government, consulting engineers, the research community, the insurance industry, and the fields of engineering, hydrologic forecasting, emergency response, water resources, planning, and others.

CASFM has grown to a membership of over 800 since its formation in 1989.  Today, in our efforts to be a vibrant and effective organization, bi-monthly general meetings are held at different locations; workshops and training classes are held a number of times each year; field trips are held as projects dictate; and an Annual Conference is held each fall. 


Members of CASFM in private industry and in public service are working toward the same cause; to reduce the loss of human life and property from flood and storm damage. In time of need there is nothing more crucial than taking a moment to stop, think, and envision a future condition that is better than the present. The only way we can secure that vision is to build back smarter, stronger and more resilient to floods and debris flows. To create a resilient state in the future, we recommend communities and government agencies take the following bold actions:

1.      Consider detailed flood hazard assessments before issuing building permits to provide time for post-flood information to be collected and community reconstruction plans to be created from that information.

2.      Support the public safety intent behind the State Floodplain Regulations by instituting them immediately on all rebuilding efforts. These regulations are available on the Colorado Water Conservation Board website.

3.      Develop Advisory Base Flood Elevations (ABFEs) for rebuilding structures in and around flooded areas. This should include high water marks from 2013 flooding, historic flood records, and FEMA Flood Insurance Study data.

4.      Rebuild outside the floodplain whenever possible to reduce the potential for damage in the future. One of the most effective ways to mitigate future losses is to relocate structures and infrastructure outside known hazard areas.

5.      Utilize CASFM members and website library for rebuilding guidance. Our 700-member organization of Certified Floodplain Mangers (CFMs), engineers, planners, scientists, environmentalists and stormwater managers are available to direct communities to assistance.

6.      Support the implementation of master plans locally and regionally by executing them during flood recovery rebuilding efforts rather than replacing in-kind.

7.      Consider FEMA repetitive flood loss clauses that affect the cost of flood insurance in areas most frequently impacted by flooding. Local governmental entities should consider available flood evidence and history before issuing permits in high hazard areas, especially in Front Range canyon watersheds and along the South Platte River.

8.      Complete a post-disaster analysis of the 2013 flood to track how federal recovery funds were spent on the disaster in individual communities. This will allow all communities to measure the effectiveness of these recovery efforts during future floods that will occur in Colorado.

As floodplain managers, stormwater managers, scientists, engineers, planners, and agents of the greater good, it is incumbent upon all of our members to work tirelessly to help our neighbors, friends, families and visitors get back on their feet. It is also incumbent upon all floodplain professionals to provide those generations with a more resilient future than the recent past or the present could provide against floods that will visit Colorado and other states again.

The CASFM organizational meetings produced the following Policy Statements:

1   Promote those plans, projects, legislation and ordinances that reduce the threat to the health and safety of the people of Colorado due to flooding and stormwater, decrease existing flood and stormwater hazards, and mitigate future flood and stormwater damages.

2   Support comprehensive floodplain and stormwater planning by an interdisciplinary team approach that is designed to achieve optimal integration of structural and non-structural flood damage reduction techniques that are realistic, feasible, practical, and sensitive to natural system forces.

3    Promote basinwide planning for solving flooding and stormwater problems that transect political boundaries and jurisdictions.

4    Promote interstate coordination of flood damage and stormwater abatement projects, programs, and ideas.

5   Disseminate scientifically based information on floods, flood damage reduction and urban and rural stormwater management to the public and decision makers and provide for a greater awareness of risk among existing and prospective floodplain users.

6    Promote the free and open exchange of ideas between the many disciplines and special interest groups that comprise the Association.

7   Objectively review proposals for flood damage reduction and stormwater management and recommend changes to those aspects of the plan which encourage unwise use of floodprone areas which will result in greater future flood losses.

8   Encourage cooperation and coordination among all occupants of floodprone lands so that flood damage reduction techniques will not adversely impact adjacent communities and individuals.

9   Encourage more detailed mapping and study of floodprone areas including the identification of areas in the floodplain which are significantly more hazardous using specific criteria such as depth of flow, velocity, rise or any combination thereof.

10  Advance the exchange of information, concepts, and approaches for innovative techniques in flood damage reduction and stormwater management through the proper and effective coordination of activities of various agencies, Federal, state and local, involved in flood related studies or work.

11  Provide and promote training and assistance programs to aid local governments in the development of rational, long term flood damage reduction and stormwater management plans and programs.

12   Provide information in terms comprehensible by the general public.

13   Encourage the development of consistent floodplain regulations in regions of the state which have mutual concerns.

14   Encourage applied and basic research directed at understanding flood and stormwater processes and problems in Colorado.
