Request for Proposal Platte River Channel Dynamics Study

• Description: Draft Final
• Date: 2/5/2001
• Water Supply Pro - Doc Type: Report/Study

Prior to the comprehensive review of items 3 through 6, the Consultant will
complete a preliminary, written review of items 1 and 2, above. The results of
this review will be provided to the State representatives. A meeting will be held
to discuss the results of the review. These discussions may result in modifications
in the contract scope and budget.
Examples of questions to be considered in the review would include:
• What data, reports, or other information was relied upon by the
EIS Team and the FWS in their NEPA/ESA review of the
Program? Was the right information used? Was it used in the
right manner? Was there important information that was not
considered?
• What are the facts and assumptions presented in the current EIS
documents? Are there any assumptions presented as facts?
Are the assumptions appropriate or do they inappropriately impact
the results? On critical assumptions, sensitivity analyses should be
completed.
• What conclusions are drawn by the EIS Team and the FWS in their
NEPA/ESA review of the Program? Are these conclusions
supported by the information they relied upon? Would their
conclusions have been different if they would have considered all
available information? If yes, in what way?
• Are there any errors, inconsistencies, or other inaccuracies in the
NEPA/ESA analysis and products?
• What is the quality (scientific soundness) or reliability (ability to
replicate) of the data or other information used by EIS Team and
the FWS in their NEPA/ESA review of the Program, and was it
used in a manner that is consistent with that level of quality or
reliability?
• Are there additional data available that should be used in the
FWS/EIS Team analysis?
• Are there data, analysis, margin errors, etc., that, if corrected,
could result in different conclusions?
• Are there additional data that must be collected before valid
conclusions can be drawn on all or some of the issues?
The Consultant's review should identify the degree to which the EIS Team and
the FWS in their NEPA/ESA review of the Program products or conclusions are
basically correct and scientifically supported.
Task 3. Independent Evaluation of Current Understanding
The Consultant will analyze the existing information identified in Task 1 and
identify the current level of understanding of channel narrowing or deepening,
sediment transport, and vegetative encroachment in and along the central Platte
