Big Hollow Forebay \& Rock Chute Wetland Feasibility Study \& Preliminary Engineering Services

Description: Des Moines County Conservation (DMCC) solicits proposals from qualified engineering and environmental consulting teams to assess the technical, regulatory, environmental, and financial feasibility of sediment and nutrient reduction projects in the Big Hollow Lake watershed in Des Moines County, Iowa. The study shall evaluate four candidate rock chute wetland sites, an in-lake single forebay, a two-forebay alternative in the upper lake fingers, and additional configurations the consultant finds technically warranted. This solicitation is for feasibility assessment and preliminary engineering only, with sufficient detail to guide project selection, agency consultation, permit and funding applications, and subsequent final design. Final design, permit applications, and construction are not included unless separately authorized. DMCC anticipates funding participation by Iowa DNR, IDALS, and potentially other partners, subject to executed arrangements. Full project details and future addenda are found in the attachments.
