Identify Conceptual Options: For each of the problems to be addressed (as determined in the preceding activity), identify at least two but no more than three conceptual solution options. Options could include physical options such as regional detention, channel widening, and constriction removal; and/or institutional options such as changes in drainage design criteria or property acquisition. Options could incorporate potentials for multi -uses for community amenity purposes. Document the options in terms of general characteristics, preliminary costs, and physical and institutional feasibility. The results of the evaluations will be informally presented to the City for their review and consideration. Evaluation of effectiveness of a conceptual solution will utilize hydrologic and/or hydraulic modeling as may be judged necessary by the Consultant. Recommended Solutions: Based upon evaluation of the selected conceptual options identified discussed in consultation with the City, recommendations for drainage facilities and infrastructure will be made.
