November 2, 2023 at 7:30 AM - Projects Committee Meeting

Rationale:  On 10/16 JWMAB members had an update meeting to discuss status of the West Fremont BRIC plan.  Moving forward there are two alternatives proposed which need to be further evaluated; improvements to the Farmland Levee and non-structural improvements.  
Proposed improvements to the Farmland Levee divided into 3 sub-alternatives:

• A. Raise levee elevation to consistent 50 year elevation $1.3 million
• B. 50 year raise + underseepage control and clay cap $6.1 million
• C. Overtopping erosion protection on landside.  $4.7 million

The other alternative to move forward for further analysis is the Non-structural Mitigation; e.g. flood risk assessment, retrofitting existing structures, property acquisition.  

 

Rationale:  On 10/16 JWMAB had our monthly Rawhide WFPO meeting.  The focus of the meeting was finalizing alternative selection, specifically the Fremont Cut-Off road raise and the two detention cells.  
Potential negative impacts of Cut-Off road raise on landowners to the west of the road was discussed after concerns were raised at the public Open House that occurred last month.  JEO needs to ground truth (survey) the LiDAR data that was used to develop the model, but they don't expect any impacts on residential structures.
Planning on the detention cells estimate ~2.5 million cubic yards of spoil that will need to be dealt with; one option will be fill for the Cut-Off road raise, but there will still be a substantial spoil left.
Upcoming milestones: 90% EA Plan development, submit to NRCS National winter 2024.

Rationale:  Bill Bos submitted certification paperwork for a completed septic system upgrade within the Shell Creek Watershed Water Quality Improvement Plan:
 

Diane Miller

$5,154.24

All septic system upgrade payments are reimbursed through our 319 Water Quality Plan.

Rationale:  Site 82 - NRCS contacted the NRD with concerns related to site 82's projected flood pool impacts; specifically related to the neighboring farmstead's grain bins, and potential DOT impacts with HWY 79.  The plan would require for the bins to be relocated, a berm to be constructed (to T.O.D. elev, ~6-8' above grade) along the easement boundary.
There was also concerns about potential pushback from DOT for permanent water being stored within existing culvert ROW.
NRCS recommends deprioritizing site 82 within the plan but keeping it in the plan for any potential future development. 

Site 77 - NRCS has concerns about the planned principal spillway pipe size on site 77.  The plan called for a 72" concrete pipe, but NRCS only has standard drawings for pipe up to 48".  Continuing on with the planned 72" pipe will present two primary obstacles: NRCS will require more time for review/evaluation, and potential installation challenges with the size of pipe.
Olsson is evaluating the feasibility of downsizing the pipe to accommodate NRCS standard drawings.  Issues that need to be evaluated with changing the pipe size will be: higher T.O.D. = more acres to acquire and more impacts to neighboring farmsteads and increased road impacts.
 

Rationale:  Attached are the monthly Progress Report and Invoice; 

Rationale:  Danielle Allen and Cody Gerdes will be available to discuss the plan for the immediate future of appraising and easement acquisition for Wahoo Creek and impacts to site 82.

Olsson real estate acquisitions invoice attached for $1,619.88
Great Plains Appraisal, Inc. appraisal invoice attached for $52,300.00
Both are 100% covered by NeDNR JEDI funds.

 

Rationale:  Reimbursement requests were sent to NRCS for $213,004.46 and NeDNR  for $70,171.27 on October 23rd.

Rationale:  With the expected NWP to be issued for sites 26AB, and 27 and to avoid potential setbacks with Endangered/Migratory Species (bats and birds) it is advisable to get prep work (tree clearing) completed before 4/1/24.  Olsson has delineated areas needed for tree removal that needs to be done prior to dam construction.
