About this file
These are construction plans for a nutrient reduction wetland project in Carroll County, Iowa, prepared by Bolton & Menk, Inc. on behalf of the Iowa Department of Agriculture and Land Stewardship (IDALS). The project, identified as IDALS No. CAR833409A and located at the Thrills Hills Wetland site, involves construction of a 3.5-acre wetland pool designed to treat water from an existing ditch system using a solar-powered pump system. The scope of work includes excavation of approximately 13,310 cubic yards of general material, placement of 4,790 cubic yards of earthfill for embankments and dam construction, installation of 250 linear feet of 18-inch reinforced concrete pipe (RCP) for the pumped inlet and 130 linear feet of 36-inch RCP for the outlet, installation of 954 linear feet of 8-inch dual-wall HDPE pipe, construction of one modified SW-513 concrete outlet structure (78 inches by 78 inches) and one SW-401 pump basin structure, placement of a solar-powered 3-phase, 3-horsepower pump system providing 340 gallons per minute at 11.25 feet of total dynamic head, installation of six anti-seep collars, placement of 29.3 tons of Class E riprap, and seeding of 2.4 acres (1.5 acres structure seeding and 0.9 acres buffer seeding). The project design includes a normal water level elevation of 1217.00 feet with a maximum 100-year pool depth of 2.0 feet and average depth of 1.2 feet, with the auxiliary spillway set at elevation 1218.50 feet. A pre-construction meeting must occur within 7 days of contract award, with construction scheduled for completion by September 1, 2027, and all seeding work to be completed by December 15, 2027. The bidders' meeting is scheduled for October 6, 2026, at 11:00 AM at Carroll Public Library, with virtual attendance available, and bids are due October 27, 2026, at 3:00 PM.
The estimated construction cost range is $175,000 to $275,000. All bidders must be registered with the Iowa Department of Inspections, Appeals & Licensing prior to contract execution. Bid security of 10 percent of the bid price is required, and the successful bidder must furnish a Performance/Payment Bond equal to 100 percent of the contract price. Written technical questions regarding the project must be submitted to Brandon Short, P.E., of Bolton & Menk with a copy to Tracy Bruun at tracy.blocker@iowaagriculture.gov by 3:00 PM on October 14, 2026, for inclusion in a final addendum. The project plans incorporate NRCS Construction Practice Standard 656 (Constructed Wetland) with a Job Class III designation for a watershed area exceeding 300 acres, with an effective treated watershed of 671.6 acres and a pumped watershed area of 2,105.6 acres. The design incorporates a pump peak flow of 0.78 cubic feet per second capturing 32 percent of the watershed flow, and includes provisions for compliance with all applicable federal, state, and local laws and ordinances, NRCS standards, Iowa Statewide Urban Standard Specifications for Public Improvements, and Iowa Department of Transportation Standard Specifications for Highway and Bridge Construction.

NOTE: THIS IS AN ALLOWED ALTERNATIVE INSTALLATION FOR CPDT
1. ALL CPDT AND CONNECTORS FURNISHED SHALL BE IN COMPLIANCE WITH MATERIAL STANDARDS ASTM F405 AND F667, AS
APPLICABLE, AND SHALL BE CLASSIFIED AS HEAVY-DUTY UNDER THOSE STANDARDS.
2. EXCEPT MODIFIED HEREIN OR OTHERWISE APPROVED BY ENGINEER, ALL CPDT SHALL BE INSTALLED IN COMPLIANCE WITH THE
ASTM 449 STANDARD PRACTICE.
3. FOR PIPES 6” DIAMETER AND SMALLER A 90° V GROOVE BOTTOM MAY BE USED, FOR ALL LARGER PIPE A TRAPEZOIDAL BOTTOM OR A CIRCULAR BOTTOM CONFORMING TO THE OUTSIDE DIAMETER OF THE PIPE SHALL BE USED. PRIOR TO THE INSTALLATION OF CPDT, CONTRACTOR MUST PROVE TO ENGINEER THAT THE INSTALLATION REQUIREMENTS, INCLUDING THE
SHAPE OF THE TRENCH BOTTOM, WILL BE ACCOMPLISHED.
4. WHERE TRENCH BOTTOM IS IN FIRM UNDISTURBED SOIL, SHAPE TRENCH BASE GROOVE. WHERE EXCESS CUT OCCURS, OVEREXCAVATE AND PLACE MINIMUM THREE (3) INCH THICK, GRAVELLY SAND BEDDING TO RESTORE GRADE. THIS BEDDING SHALL MEET THAT REQUIRED FOR TRENCH INSTALLATION TYPE 3 ON PLAN SHEET C.02. IF DUE TO CONTRACTOR ERROR THIS MATERIAL AND WORK IS SUBSIDIARY TO THE INSTALLATION OF THE PIPE. CONTRACTOR MAY SUBSTITUTE PIPE BEDDING ROCK
AS THE BEDDING MATERIAL.
5. NATIVE SOILS MAY BE USED AS BACKFILL MATERIAL UNLESS UNSTABLE TRENCH CONDITIONS PREVENT THE TRENCH BOTTOM HOLDING THE SHAPED GROOVE. IF TRENCH BOTTOM WILL NOT HOLD GROOVE SHAPE CONTRACTOR SHALL NOTIFY ENGINEER IMMEDIATELY. A FLAT BOTTOM TRENCH INSTALLATION WILL THEN BE ASSUMED. THE REQUIRED BEDDING MATERIAL WILL BE
PAID UNDER THE TILE TRENCH STABILIZATION AND CRADLING ROCK BID ITEM.
6. MINIMUM TRENCH WIDTH IS PIPE OUTSIDE DIAMETER PLUS FOUR (4) INCHES FOR PLOWED INSTALLATION AND PIPE OUTSIDE
DIAMETER PLUS TWELVE (12) INCHES FOR OPEN TRENCH INSTALLATION.
7. ALL LATERAL CONNECTIONS, ELBOWS, TEES, ALIGNMENT CURVES, START HOLES AND ALL PORTIONS OF THE TRENCH NOT MEETING THE GROOVED TRENCH INSTALLATION REQUIREMENTS SHALL BE FILLED TO A MINIMUM OF SIX (6) INCH COVER OVER THE PIPE WITH GRADED CRUSHED STONE OR GRAVEL AS SHOWN ON TABLE 2 OF THIS SHEET. UNLESS DUE TO CONTRACTOR ERROR THIS BEDDING MATERIAL WILL BE PAID UNDER THE TILE TRENCH STABILIZATION AND CRADLING ROCK BID ITEM.
8. MANUFACTURER'S ENDCAPS SHALL BE INSTALLED AT THE TERMINATION OF EACH LINE UNLESS A CONNECTION TO AN EXISTING
DRAIN IS MADE.
9. WITH THE INSTALLATION OF THE FIRST REACH OF CPDT ON THE PROJECT, CONTRACTOR IS REQUIRED TO WORK WITH THE
ENGINEER TO CHECK AND CONFIRM THAT THE PIPE STRETCH, IF ANY, DOES NOT EXCEED 5%.
10. ALIGNMENT TURNS MAYBE MADE USING EITHER A MANUFACTURED FITTING OR CURVING THE LINE WITH A 25' MINIMUM
RADIUS.
