This is a final design plan document prepared by JEO Consulting Group, Inc. for the Iowa Department of Agriculture & Land Stewardship, Division of Soil Conservation and Water Quality, detailing the CAR853313A Nutrient Reduction Wetland Construction project in Carroll County, Iowa. The project involves construction of a traditional breakpoint nutrient reduction wetland with comprehensive infrastructure including approximately 17,500 cubic yards of earthwork, 2,595 square feet of steel sheet pile weir construction, water control structures, inlet risers, 136 linear feet of 15-inch diameter corrugated metal pipe (CMP), 812 tons of riprap, 98 cubic yards of concrete grout, 12.7 acres of seeding, and 2,175 linear feet of 9-inch diameter straw wattle for erosion control. The project encompasses a 317-acre drainage area with a permanent wetland pool area of 2.09 acres, normal pool elevation of 1,107 feet, average pool depth of 2.26 feet, and maximum pool depth of 7.0 feet. The design includes a dam structure with a berm elevation of 1,111.5 feet, principal spillway, drawdown structure, and stilling basin. The estimated sediment storage capacity is 59 years. Construction must comply with Iowa NRCS standard specifications and construction standards. The contractor is responsible for calling Iowa One Call at least 48 hours prior to beginning excavation, notifying utilities 48 hours before commencing work, and submitting a construction schedule at the pre-construction conference before work begins.

The project location is defined by survey control points and a permanent easement area totaling 8.13 acres across properties owned by David Remsburg, Dozier Trust, and VG Legacy Farms, LLC. All site plan information is based on U.S. survey feet measurements. The design was prepared by Juan A. Arellanes, PE, and Jacob T. Miriovsky, PE, of JEO Consulting Group, Inc., with final plan approval dated April 15, 2025. The contractor bears full responsibility for determining the existence and exact location of all utilities and for avoiding damage; any damage due to contractor negligence must be corrected at the contractor's expense. Additional costs including excess material hauling, overhaul, and any necessary reshaping for drainage are considered incidental to the project with no additional payment authorized. If a cultural resource is identified during construction, all work must halt and the NRCS archeologist must be notified immediately at 515.323.2253. Contractors must maintain current records on measurements, materials deliveries, placements, and as-built drawings and attend progress meetings as requested by the engineer and owner.

1) THE SLEEVE TYPE NEOPRENE GASKET SIZE SHALL BE 3/8" THICK WITH A MINIMUM WIDTH OF 7" CENTERED ON THE PIPE JOINT AND FASTENED AT ENDS TO FORM A FULL CIRCLE. IN LIEU OF A NEOPRENE GASKET, ASPHALT OR TAR BASED MASTIC MAY BE USED FOR DETAIL "A" AND "B". (SEE NOTE 5)

2) IN CONNECTING THE PIPE SECTIONS, THE COUPLING BANDS WILL BE CENTERED ON THE PIPE JOINT AND ALIGNED FOR COMPLETE AND TIGHT NESTING OF CORRUGATIONS BETWEEN COUPLING BAND AND EACH

PIPE SECTION. RODS AND LUGS ON COUPLING BANDS WILL BE INSTALLED ACCORDING TO THE

DRAWINGS. THE NUTS ON THE RODS WILL BE TIGHTENED WITHOUT OVER STRESS AND WILL BE

RETIGHTENED AT LEAST TWICE AFTER INITIAL INSTALLATION, AT INTERVALS OF APPROXIMATELY 1/2 HOUR. THE FINAL TENSION ON THE RODS SHALL BE DETERMINED BY THE ENGINEER. BACKFILLING AROUND THE PIPE, EXCEPT AT COUPLING BANDS, MAY PROCEED DURING THE INTERVALS REQUIRED FOR

TIGHTENING BANDS.

3) BEFORE COUPLING BANDS ARE INSTALLED ON RIVETED PIPE, THE PIPE SECTIONS THAT ARE TO BE CONNECTED SHALL BE ROTATED SO RIVETS ON THE PIPE ARE ON THE SIDE OF THE PIPE (SEE DETAIL "A")

AND THE INSIDE LAPS ARE POINTED DOWNSTREAM.

4) ON BITUMINOUS COATED PIPE, REMOVE EXCESS BITUMINOUS COATING FROM CORRUGATIONS WHERE

BANDS AND PIPE JOIN.

5) THE ENDS OF THE TWO PIPE SECTIONS AND THE LAP SEAM WILL BE COATED WITH 1/4" OF ASPHALT OR TAR BASED MASTIC (ASTM A849, TROWEL GRADE) FOR DETAIL "A" COUPLING BANDS.
