Engineer’s Discussion:

1. Dan Jensen gave an overview of the project plans and specifications:

a. Project proposed a constructed wetland of 6.1 AC.

b. The main outlet is a sheet pile weir.

c. Tile work is based on information from the landowner. Field adjustments may be necessary.

d. There will be a Corrugated metal water control structure with stop logs for drawdown and control of water elevation.

e. There is a high pressure gas main on the norther side of the project. A permit has been obtained from Northern Natural Gas. The contractor is responsible for understanding and complying with the permit. Contact NNG when work is scheduled for coordination.

Following Dan’s presentation of the project, there were some questions from the attendees:

2. Since this project is not being bid during the typical months of February/March, can the completion deadline be extended?

Answer: Please refer to Addendum No. 1, that explains the completion deadlines for the project has been extended to November 1, 2024 for all work except seeding and to December 15, 2024 for seeding.

3. Seeding:

a. Seed dates have been updated according to the Iowa Conservation Practice 327 and Critical

Area Planting of the Iowa Conservation Practice 342. Specifically – if structure/buffer/switch grass have different seed dates and if frost/dormant seeding can happen over winter (provided there isn’t snow cover).

Answer: Please refer to Addendum No. 1, which is modifying the specifications for Bid Item #3 Switch Grass, including modifying the seeding window dates to follow the recommendations of Iowa CP 342 for native grass.

Page 5 of 6 revised 9/11/23

b. How will seed bed be prepped outside of the grading limits within the easement?

Answer: Refer to Specifications IA-06 (Pages 3 and 4 of 5), with specifications for seedbed preparation and Addendum No. 1.

c. Can the seeds to broadcasted, instead of drilled?

Answer: Refer to Specifications IA-06 for Bid Items #2, #3 (with Addendum) and #4. With specifications for seed application with a drill. Bid Item #2 allows for broadcasting or hydroseeding, or by hand, in areas that are not accessible to drills or other equipment. The Division must approve this.

d. There will be brome on embankment and prairie and switchgrass on the buffer. The landowner would like an enhanced mix.

Answer: The bids should follow the specifications and Addendum No. 1. Any upgrade to an enhancement mix must be first reviewed and approved by the Division, and the local NRCS office, prior to seeding. However, if there is a price difference, the landowner will be responsible for that additional cost of the seed.

4. Can the project use an “enhanced” buffer seeding mix?

Answer from IDALS: All seeding mixes to be used for this project must be approved by NRCS first.

Enhanced seeding mixes may be allowed, if they meet NRCS specifications and are approved by NRCS and the Division, however, if there is a cost difference, it must be paid by the landowner and the landowner must agree to the cost difference prior to commencing of the seeding.

5. Who will do construction staking?

Answer: Shive-Hattery has surveyed and staked the conservation easement. They will also do the surveying and staking prior or during construction. CAD files are available for bidders and the selected contractor.

6. What type of soils are in the wetland site?

Answer: A geotechnical investigation was conducted on the site and the results have been included in Appendix III “Other documents”.

7. If we encounter bedrock during driving the sheetpile, can the sheetpile be cut?

Answer: Specification IA-013 Sheet Piling, 3 (Page 1 of 3) states: “Piling shall be driven to the full depth shown on the drawings unless otherwise approved by the engineer.” If refusal is encountered, coordinate with the engineer. The Division must first review and approve any change of the designed sheet pile length, or any other change to the design.

Page 6 of 6 revised 9/11/23

8. Will there be tree clearing?

Answer: Minor clearing is needed, there is no known “junk” buried on the farm.

9. Will cropland be involved?

Answer: No, except for access.

10. If I win the bid for the first project, can I withdraw their bid for the second project?

Answer from IDALS: Under the “Instruc�ons for Bidders, Document BB”, states “07 WITHDRAWAL OF BIDS – Bids may be withdrawn any time prior to the scheduled closing time for receipt of bids;

but no bid may be withdrawn for a period of thirty (30) calendar days thereafter.”

o Note that the bids for both projects are due by 3:00 PM on Thursday

September 14, 2023. Refer to Addendum #1, with has extended the bid opening date for both projects from 3:00 PM September 12, 2023 to 3:00 PM September 14, 2023.

11. Can we use single wall no perforated tile?

Answer: Per Specifications IA-046, Special Requirements, B,1,a &B Page 4 of 5 the two tile line items are for 8” Dual Wall HDPE and 12” Dual Wall HDPE meeting ASTM 2648. No single wall tile is proposed for this project and cannot be used.
