About this file
This amendment document clarifies specifications for Invitation to Bid #32701-13862, issued by the Tennessee Department of Environment and Conservation and the West Tennessee River Basin Authority (WTRBA), for stream maintenance and restoration services at Running Reelfoot Bayou in Gibson County. The project encompasses floodplain bench excavation across four phases, with approximately 1,000 hours of standard excavator operation, 1,500 hours of amphibious excavator operation, 1,500 tons of rip rap material installation, 60 acres of temporary vegetative stabilization, and 40 acres of permanent warm-season grass establishment. The ITB was issued April 29, 2026, with a questions and comments deadline of May 6, 2026 at 10:00 a.m. Central Time and a response deadline of June 5, 2026 at 2:00 p.m. Central Time. No pre-bid walk-through was scheduled. The contract period extends for 36 months to completion, with work to commence within 30 days of receiving written Notice to Proceed. The State retains the discretionary option to execute cost negotiations with respondents.
Amendment Two provides critical clarifications regarding excavation volumes, payment adjustments, material balancing, drainage structure specifications, and allowance line items. Cut and fill volumes will not receive payment adjustments based on field variations; contractors must balance material on-site through adjustments to back slopes, berms, and field elevations without importing off-site material. All four phases must be individually balanced. The drainage structure allowance of $500,000 compensates material costs only, with installation paid through other line items; flapgates are required on all outlet pipes. The landowner impact allowance is $450,000 for 300 units at $1,500 per unit and covers one year of impact without repeatable payments on the same parcel. Additional allowances include $500,000 for third-party services, $200,000 for materials (including native seed and mulch), and $500,000 for construction contingency. Contractors are responsible for obtaining affected landowner contact information, though WTRBA has preliminary outreach information available for sharing. No bid bond is required, and no permits have been issued as of the amendment date, with WTRBA currently obtaining necessary permits.

QUESTION / COMMENT STATE RESPONSE
1. With respect to the cut and fill volumes in the revised plans for excavation, once clearing is complete-if the volumes differ from the plans will adjustments be made to the payment of the lump sum item?
No. There may be adjustments in the field to vary the farmable slope to help balance the site but no payment adjustments will be made.
2. Does the contractor have the full 36 months to complete the lump sum excavation item?
Yes. Consideration should be given to the landowner impact allowance that is intended for 1 year of impact and is not intended for repeatable payment on the same parcel when determining the phasing of construction
3. Will this project exercise the best and final offer option?
The State, at it’s sole discretion, may exercise cost negotiations with Respondents.
4. Will a list of the affected/adjoining land owners be provided or contractors responsibility to obtain contact information?
It will be the responsibility of the contractor to obtain this information.
WTRBA has obtained much of this information through preliminary outreach to local producers that can be shared.
5. I see the requirement for a payment and performance There is no requirement for a bid bond included in the terms and conditions.

QUESTION / COMMENT STATE RESPONSE
bond. Is a bid bond required for this project?
6. Is there a timetable on the floodplain portion of this contract?
The contract period of 36 months to completion is the only official timetable.
This is also referenced in question #2.
7. There is an import of material in the upstream right section.
Where will that shortage be located and where will the material come from on-site?
AMENDMENT 2 CLARIFICATION
There will not be any import of off-site material. Each phase will be balanced to itself. Adjustments will be made to the back slope to the field as well as the elevation and width of the berm if needed to balance the material excavated.
8. Can you tell me if there will be a pre-bid walk through for this project?
There is not a pre-bid walk through scheduled for this site.
9. In the Floodplain Bench plans is there a break point which divides the downstream left & right and the upstream left & right?
Please refer to the updated set of plans.
References on sheet C2.0 should be to phase 1-4. Any reference to left or right bank is not the appropriate construction set of plans.
Ph 1 – downstream Hwy 78 south bank
Ph 2 – downstream Hwy 78 north bank
Ph 3 – upstream Hwy 78 North/West bank
Ph 4 – upstream Hwy 78 South/East bank
10. There will be a net cy in dirt excavated, what are we to do with the extra?
This will be the responsibility of the contractor. Adjacent uses negotiated and permitted separately with landowner’s will be acceptable or the 15:1 back slope to the adjacent ag fields may be adjusted to balance the material on site.
AMENDMENT 2 CLARIFICATION
The above statement is still true, but I wanted to highlight this section as it supports the clarification made for question #7.
11. There are two sets of plans one
Floodplain Bench & the other RRB Mid Bench but they appear to be the same plans.
Plans have been updated on the shared folder for clarification. Please refer to sheet C2.0. The excavated material table should have reference to phase 1
– 4 on the correct plan set. If you see a reference to left and right bank, you need to get the corrected plan set.
12. The Drainage Structure
Allowance states that it will pay for structures delivered and installed on-site. Then states installation of structures will be paid in other line items can you clarify.
The wording was intended to clarify that staged materials will not be paid for.
The structure must be “installed” at the time payment. The drainage structure allowance is solely for material costs.
The act of installing the structures will be paid for by appropriate other line items.
