Re: Cache La Poudre River Master Drainageway Plan Revisions —
50-Year Flood Damage Assessment
Dear Bob,
Per your request, we have considered the level of effort necessary to evaluate the flood
damages associated with 50-year flood event, assess improvements required to mitigate
damages, and add a brief discussion to the Master Drainageway Plan documents. Following is
our proposed scope of work, cost estimate, and schedule to compete this task.
SCOPE OF WORK
Revisions to the Draft Cache La Poudre Master Drainageway Plan (MDP) have been addressed
under a previous task order and the final draft of the MDP is currently being prepared. The
objective of this supplemental task order is to add additional information to the MDP addressing
estimates of damages associated with the 50-year flood and the cost for improvements that are
needed to mitigate the 50-year damages. A summary of the tasks required to complete the 50-
year flood damage assessment is as follows:
Evaluate 50-year damages for FDRs — Using the existing MDP hydraulic model and EAD model
results, flood damages will be evaluated at each of the Flood Damage Reaches (FDRs)
identified in the MDP.
Determine 50-year improvements - One -hundred year flood improvements identified in the MDP
will be modified to provide a 50-year level of protection for the affected FDRs.
Estimate 50-year improvement costs — Once the 100-year improvements have been modified,
the cost estimates will be revised to reflect the 50-year improvements.
Meet with City to discuss results — Ayres Associates project manager will meet with City staff to
discuss the results of the 50-year flood damages and improvements.
Summarize results in Master Drainageway Plan and Executive Summary — The results of the
assessment will be summarized and incorporated into the MDP documents.
