RE: Emergency George Rist Ditch Repairs,Loan Contract#C150380
Additional Loan Amount for George Rist Ditch Flood Repairs
Dear Mr. Hernandez:
This letter is being sent on behalf of the Consolidated Home Supply Ditch and Reservoir Company
(CHSDRC)to request an increase in the loan amount for the George Rist Ditch Flood Repairs related to
the September 2013 floods.
7a IL
The original loan amount was$448,440.00. addition to the loan amount, CHSDRC received two-
$25,000 grants from the CWCB. Total fundin to repair the flood damage was $498,440.00. CHSDRC is
requesting an increase in the loan amount to$518,440.00 or 15%. This would bring the total funding for
repairs to $568,440.00. All activities related to the original loan amount have been complete, including
the addition of an overflow crest weir and headgate at the western breach. The headgate was a
replacement for an existing gate destroyed in the flood. The overflow crest weir was installed to protect
the ditch from future overtopping. These additional items were fully covered within the existing funding
amounts. A vicinity map of these repairs is attached as Figure 1. Pictures of the repairs are attached as
Figures 2 and 3.
The increase in the loan amount is a request for additional repairs already completed to the George Rist
Ditch, including ditch repairs and debris removal below Dry Creek,replacing the damaged flume,
removal of a bridge downstream of the east breach,completion of the ditch rider road restoration from
headgate through the breach repairs. The additional loan amount would cover the cost to complete
additional repairs at the east breach and a damaged section of ditch downstream of the east breach that
was not discovered until this spring.
CHSDRC works directly with Mike Orback for annual maintenance and start-up of the ditch each year.
It was during these activities that additional debris and damage to the George Rist Ditch was discovered
at a point downstream of the Dry Creek structure. The George Rist Ditch and Dry Creek converge and
share the same channel for approximately 350ft before Dry Creek returns to the channel downstream, as
shown in Figure 4. The debris,damaged section,and subsequent repairs are shown in Figures 5 and 6.
The cost to complete this was $6,739.00.
The existing flume was damaged during flooding and was known to have operation issues prior to the
flooding. After additional field investigation and conversations with the Big Thompson River
Commissioner, it was determined that the existing flume could not be repaired. Deere&Ault designed a
long throated flume to replace the damaged flume. The damaged flume was demolished and removed
