About this file
These construction plans, prepared by Bolton & Menk, Inc. for the Iowa Department of Agriculture and Land Stewardship (IDALS), detail a Nutrient Reduction Wetland project located in Greene County, Iowa. The project, identified as IDALS No. GRE853019D, involves constructing a wetland with a 1.5-acre pool area designed to reduce nutrient runoff from a 255-acre watershed. The project includes excavating the site to specific elevations, installing drainage tile, constructing an outlet riser structure, and implementing seeding and erosion control measures. Key quantities include 19,754 cubic yards of excavation, 493 linear feet of 12-inch HDPE dual-wall pipe, two concrete manholes, two outlet riser structures, and 21.5 tons of rip rap. The project is scheduled for September 2025, with bid plans prepared on September 11, 2025.
The wetland design incorporates specific hydraulic characteristics, including a normal water level at 1076.00 feet, a maximum pool depth of 1 foot, and an average pool depth of 0.96 feet. The project aims to manage water flow, with a 25-year storm peak inflow of 82 cubic feet per second and a peak outflow of 71 cubic feet per second. The site will include a sediment forebay, turf reinforcement mat, and structural and buffer seeding to stabilize the area. The drainage tile system will be re-laid with improved capacity, increasing from 0.78 cubic feet per second to 2.02 cubic feet per second. The project is part of a broader nutrient reduction strategy, likely funded through state agricultural and conservation programs.
