fund loan program to enable communities to address flood mitigation, stream rehabilitation, and
watershed improvements.

Public Informationrrechnical Assistance. Respondents identified nearly 500 miles of unmapped, 1 DO-year
floodplain. Statewide, CWCB staff and MWE project staff estimate there are at least 1500 miles needing to
be studied and mapped. In addition, floodplain mapping completed nearly 20 years ago needs to be
updated. The community surveys also identified the need to (1) establish a program of information
sharing to disseminate information relating to flood hazards, flood mitigation techniques, and stream
corridor values, and (2) provide technical data, training, and education to local decision makers who deal
directly with watershed, stream corridor, and floodplain management.

Policv and Criteria. Policies should be established concerning: (1) creating a storm water detention policy
to control excess runoff from new development limiting the increase of peak flows in the floodplain, (2)
establishing a statewide wetlands banking process to allow reallocation of existing and new wetlands
resulting from multi-objective stream corridor management. New criteria should be established:
(1) defining baseline conditions (100 year event) for stream corridor management activities, (2) defining a
higher level of protection (500 year event) than baseline conditions for critical facilities, and (3) creating
and adopting a statewide model storm water criteria manual.

At meeting number five on March 12, 1998, the Committee acted on the following final products for the
project. The discussion topics were:

· Prepare a project informational brochure and select an appropriate title
· Discuss the final recommendations for the project needs categories
· Review and discuss on the consultant's draft final project report

The Steering Committee, CWCB, and consultant decisions on March 12th were:

Project Infonnatlonal Brochure. The brochure should be entitled "Stream Rehabilitation and Flood
Protection Needs in Colorado." The brochure content should include: "What's the Need?" (survey
findings), Requested Funding Mechanisms, Values of Stream Corridors, Goals for Streams Corridors, "How
Do We Get There?", and Benefits.

Final Recommended Project Need Categories. The Committee agreed on the final need categories that are:
· Planning Assistance - River Basin Multi-Objective Plans and Floodplain Mapping
· Funding Implementation - Revolving Loan Fund and Flood Emergency Account
· Public Information/ Technical Assistance - Floodplain Hazard Awareness and GIS
· Policy and Criteria - Establish Minimum Standards

Review and Discussion on the Draft Final Project Report. The Committee members were requested to
provide comments on the contents of the draft report by March 19, 1998.
