<br />Task 7 <br />Paleoflood data, which represent the largest floods in about the past 5,000 to 10,000 <br />years, has recently been identified and documented by the U.S. Geological Survey <br />A W A has coordinated with Dr. Jarrett to procure and use paleoflood data for the Cherry <br />Creek basin in its storm analyses. Additional field trips to collect paleoflood data will be <br />made within the Cherry Creek basin as well as within adjacent drainage basins as <br />required. Dr. Jarrett will provide technical assistance to Mr. Trieste with paleoflood site <br />selections and evaluations as well as PSI evaluations at locations on the Palmer divide. <br />Mr. Trieste will incorporate the paleoflood data into his HEC-l modeling effort. <br /> <br />Task 8 <br />Reasonableness and consistency checks, such as continuity in time and space, will be <br />applied to the PMP estimates. As a minimum the following aspects will be evaluated: <br />1. Definition of the basin and storm study regions <br />2. Classification of the meteorology of extreme storms <br />3. Terrain classification <br />4. Moisture maximization process <br />5. Severe storm transpositioning <br />6. Design storm positioning <br />7. Development of storm spatial and time distributions <br />8. Comparison with other site-specific PMP studies to evaluate the PMP results <br />for reasonableness and consistency <br />These comparisons will emphasize consistency of the physics associated with the <br />PMP calculations. Consistency among assumptions made during various phases of the <br />project will be emphasized. <br /> <br />Task 9 <br />This task is responding to Task X in the RFP. This task will be addressed as one of <br />the first issues in the project since it is somewhat a stand alone task A W A will contact <br />various agencies involved with dam safety evaluations and collect and document their <br />policies related to antecedent rainfall/flood criteria. These will included both federal and <br />state agencies. <br /> <br />Task 10 <br />Interim reports will be provided as described in the deliverables portion of the <br />RFP. The final report will be inclusive for the entire project but will refer to the interim <br />reports for details of previous tasks. Emphasis will be placed on complete documentation <br />of data, methods developed and techniques used. The final report will compare the <br />results of the study with the NWSSS and document the differences along with the reasons <br />for those differences. <br />
