Development of Alternatives. The Consultant shall identify and evaluate potential design alternatives that would meet the City’s defined project objectives for both short-term design solutions (to improve the existing drainage conditions) and long-term design solutions (that would further improve drainage conditions if necessary and provide for pedestrian and bicycle accommodations). These evaluations are not to be carried beyond the point of establishing the feasibility of each concept as a design alternative; only those significant environmental and geometric and/or hydrologic design constraints that bear on the feasibility should be identified. Short-term solutions may include, but are not limited to, converting the open channel system to a closed conduit system, ditch grading revisions, cross culvert diversions at select locations, etc. The need for guide rail shall be evaluated. The Consultant will perform hydrologic and hydraulic analysis on the storm sewer network for each design alternative. The Consultant shall prepare the necessary drawings for each design alternative analyzed. Drawings may include colored concept plan(s) with applicable callouts, typical sections and roadway and/or ditch profiles. The Consultant shall determine impacts to existing features (e.g. trees, roof drains, grading, driveways, etc.) associated with the proposed alternatives. The Consultant will prepare and submit a matrix identifying all pros and cons for all design alternative concepts for the City’s review. The Consultant will meet with the City to discuss the concepts, using the drawings as discussion aids to describe the relative order-of-magnitude costs and pros and cons of each.
