Phase IIA focuses on identifying alternatives for mitigating the hazards and problems, evaluating the alternatives for flood mitigation potential and cost effectiveness, and recommending a preferred alternative and flood control policy.

This report presents the results of both a qualitative and quantitative analysis of the drainage problems associated with the South Branch, Upper Carmack watershed. Also included is an economic assessment of the damage potential associated with three distinct storm events.

This study identifies the drainage and flooding hazards within the watershed and develops alternatives to address those hazards. It is a comprehensive study that estimates flood and erosion potential, maps watercourses, identifies existing and potential problems and develops preliminary solutions and standards for sound floodplain and stormwater management.
