Truckee River Flood Management Authority Locally Preferred Plan Discussion of Project Elements Cost Estimate
Chronology of Project Cost Development • In December 2012 The USACE completed MCACES for the National Economic Development Plan (2012 NED). • In April of 2013 HDR developed MCACES using quantities developed for the Local Preferred Plan (2013 LPP) and, except for a few exceptions, used the contingencies from the 2012 NED. • In February 2017 HDR developed a Phasing Plan based on the 2013 LPP. During this effort the project costs were escalated from 2013 costs to 2016 cost. • In December 2013 the USACE updated the cost estimate for 2012 NED (Certification date of December 2013). – (2013 NED)
Basis for Contingencies for 2013 LPP • The contingencies were largely obtained from 2012 NED.

Questions Regarding Project Elements Cost Estimate Spreadsheet 1. Are contingency costs also added on top of land costs? 2. We have been told that contingency costs are 35%, but the spreadsheet shows 37.9%. That is a difference of $5.7M 3. Are the costs for the NTD included in our estimate? 4. There is almost $19M for “Habitat and Feeding” that is not in the Yellow Book. What is this line item? 5. There is $4.7M for “McCarran Levee/UNR (S) that is not in the Yellow Book. What is this line item? 6. Are the completed projects eligible for Army Corps funding? To put it another way, could we apply for part of that $180M now? 7. Could we be provided with an overlay of the 1997 flood for downtown Reno?
1. Are contingency costs also added on top of land costs? • Yes

3. Are the costs for the North Truckee Drain included in our estimate? The costs for the North Truckee Drain was included in 2013 LPP Cost Estimate as an estimated cost as it had not been constructed at the time of the report.
3. Continued Then for the Phasing Plan the NTD cost was updated with the actual bid construction cost and treated as a sunk cost or cost to date.
4. There is almost $19M for "Habitat and Feeding" that is not in the Yellow Book. • This is the necessary work for habitat mitigation/restoration.
5. There is $4.7M for "McCarran Levee/UNR (S) that is not in the Yellow Book. This Levee Reach on Right Bank was required for Hydraulic Mitigation, a cost was developed in 2016 and unit costs from 2013 LPP were applied.
6. Are the completed projects eligible for Army Corps funding? To put it another way, could we apply for part of that $180M now? 7. Could we be provided with an overlay of the 1997 flood for downtown Reno?
