RE:

Introduction
Since December 1967, the Board has designated and approved, based on statutory responsibility, more
than 500 floodplain information reports and maps containing 100-year floodplain information. The
Flood Protection Section has prepared or sponsored the preparation of numerous other technical
documents relating to floodplain management in various ways. In addition, local governments, federal
agencies and private entities have prepared other flood-related technical documents. The CWCB does
not have statutory authority and therefore has never formally approved any such documents in the past.

Staff is now suggesting that the Board consider "formal approval" of flood-related technical documents
in the future. Staff at this time is onlv requesting the Board to consider and discuss the concent of a
future approval process for technical information other than 100-vear floodplain studies.

Backl!round
In Sections 30-28-111, C.R.S. (counties) and 31-23-30l, C.R.S. (municipalities), the CWCB is given
the statutory responsibility to "designate and approve ... any storm or floodwater runoff channel or
basin ..." in Colorado for subsequent designation by the pertinent local government. In carrying out
that responsibility, the Board has designated and approved over 500 floodplain information reports and
maps since December 1967.

The Flood Protection Section staff has prepared or participated in the preparation of many other types of
technical documents related to floodplain management and continues to do so. Local governments,
federal agencies, and private entities have also prepared such documents and will do so in the future. In
the past, specific formal action by the Board was not requested by staff due to the lack of statutory
authority for such action. A sample list of other types of flood-related documents include:
