C. Analysis — Proposed Hydrologic and Hydraulic Analysis <br />Hydraulic Analysis — Improvement Concept Development <br />Based on the results of the Existing Conditions model, improvement concepts will be <br />developed to improve the functionality of the study area to meet City Criteria. <br />Dynamic hydraulic models will be analyzed for 5-, 10-, and 100-year storm <br />frequencies. Improvements may include storm sewer improvements, open channel <br />ditch improvements, detention/retention ponds, or a combination of improvements. <br />Improvement concepts will be developed to accommodate a phased improvement <br />implementation. <br />D. Reporting <br />Technical Report and Exhibits <br />The technical report will include a discussion of the work performed, general <br />methodology, assumptions applied during the course of study, a discussion of the <br />study goal, the reported drainage problems, a discussion of deviations from general <br />methodology, conceptual project alignment, a high level opinion of probable <br />construction cost estimate, and a discussion of findings and recommendations. A <br />draft report will be compiled to include text, exhibits, and appendices for the City's <br />review. The final models, shapefiles, databases, and worksheets used will be <br />included on a DVD or file share site. One (1) round of comments from the City will <br />be used to revise and update draft memorandum and attached exhibits. <br />Model output and exhibits will be created after all modeling iterations have been <br />completed and the technical report has reached the draft phase. <br />E. Direct Costs and Reimbursable Expenses: <br />1. Reimbursable expenses will be billed to the Client by invoice. Reimbursements shall <br />be the actual invoice costs. A reimbursable expense budget has been established <br />as a not -to -exceed amount without prior approval. Reimbursable expenses shall <br />include printing and reproduction, deliveries, and mileage. <br />A-2 <br />
