This is a construction plans document prepared for the Iowa Department of Agriculture and Land Stewardship (IDALS) for a nutrient reduction wetland project (CER962218C) located in Cerro Gordo County, Iowa. The project involves construction of a tile zone wetland designed to treat a 422-acre watershed through a constructed wetland system with a normal pool elevation of 1233.00 feet and a maximum pool depth of 10 feet. The scope of work includes site stripping and preparation, excavation of approximately 32,583 cubic yards, installation of concrete structures (one modified SW-513 inlet, one modified SW-513 outlet, two SW-401 manholes), placement of reinforced concrete pipe (RCP) in various sizes (12", 15", and 24"), installation of dual-wall high-density polyethylene (HDPE) pipe and corrugated polyethylene drainage tubing (CPDT), placement of 22 tons of Class E riprap, 1,202 square yards of turf reinforcement mat, and seeding of 10.2 acres (9.1 acres of buffer seeding and 1.1 acres of structure and channel seeding). The project is designed to serve multiple property owners and includes construction access provisions through various parcels in the area.

The construction plans detail specific installation requirements for pipe bedding, trench configurations, inlet and outlet structure modifications, grading plans with designated spoil areas, and seeding specifications. Design criteria indicate the wetland pool will encompass 6.3 acres at normal water level with a storage volume of 6.2 acre-feet, with projected high water levels of 1240.04 feet for a 25-year storm and 1241.20 feet for a 100-year storm event. The document includes detailed profiles, cross-sections, and specifications for the 15 miles of tile main relaying and new tile installations, with existing clay tile to be removed or crushed in place throughout the wetland pool area. Existing storm drain analysis shows reduced peak outflows under proposed conditions across all storm frequencies, with the 100-year peak outflow reduced from 718 cubic feet per second to 59 cubic feet per second. Professional engineer Brandon C. Short (License #29449) sealed and certified all construction plans dated May 27, 2025, with plans prepared by Bolton & Menk, Inc. located in Ames, Iowa.

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.
