CHANGE ORDER
NO. 01
PROJECT TITLE: Water Supply Vulnerability Study Work Order 01
SERVICE PROVIDER: Stantec Consulting Services, Inc.
WORK ORDER NUMBER:01
PO NUMBER: 9175434
DESCRIPTION:
1. Reason for Change: Task 3 There was an additional cost for purchasing 2016 imagery with
adequate coverage of the GMA extent which was not included in the other direct costs of the original
budget. Task 5 Decision was made to perform similar modeling for tributaries in the C-BT system as
for the Poudre Basin. This will produce a better, more consistent final product.
2. Description of Change: See attached Scope of Work
3. Change in Work Order Price: $16,469
4. Change in Work Order Time: None

Introduction
Recommendations from the Literature Review and Hydrologic Approach Workshop included hydrologic simulation of flows
under future conditions for the basins that serve as input to Northern Water’s CBT model. The simulation of flows in those
basins would use the same approach and tools as the ones proposed for the Poudre River Basin, for consistency and to
improve the accuracy on the water availability estimate for the CBT system under future conditions. Using hydrologic
models to simulate flows for the CBT model was not included in base-proposed approach, so the scope of work and
estimated additional effort to include the explicit hydrologic modeling in these basins in Fort Collins Utilities Vulnerability
Study (FCUVS) is presented herein.
Also, included in this document are the additional cost for purchasing the 2016 imagery for the area covering the general
management area (GMA) extent that was not included in the other direct costs of the original budget.
Changes from Original Scope of Work
Task 3 - FUTURE WATER DEMAND CONSIDERATIONS
RTI has acquired a 2016 satellite image for the entire GMA. This change order covers the difference between the cost of
this image and original budget for the purchase.
Task 5 – DEVELOP POTENTIAL YIELD CHANGES
RTI will use the Joint Front Range Climate Change Vulnerability Study (JFRCCVS) calibrated models to simulate the
rainfall-runoff processes in the basins used by the CBT model, which include the upper Colorado River, Fraser River,
Willow Creek and Big Thompson River. RTI will use the same procedures and underlying assumptions selected to
simulate future conditions in the Poudre River basin for the FCUVS, including variability from the tree-ring reconstructions
and several trends of changes in precipitation and temperature, to generate a set of ensembles to represent variability
and climate.
The hydrology modeling approach selected uses transition probabilities from tree-ring paleo reconstructions in the South
Platte basin as the base for the future weather generation, to capture potential future hydrologic conditions. RTI will use
the existing models and tools developed for the base analysis, and will apply the same method proposed for the Poudre
Basin to generate hydrology sets for the additional basins. RTI will run the rainfall-runoff models to estimate the resulting
flows of the generated hydrology sets. RTI will process and organize the results to be used by the yield and CBT models.
Budget
Table 1 shows the additional required hours and the budget for the additional tasks. Additional project management time
to process the change order and the subconsultant markup are included in the budget. The total of the requested change
order is $16,469.
