The West Dubuque Solar Garden, the largest solar array in the State of Iowa, is located near the Dubuque Industrial Center West.
The site was formerly an agricultural field which was repurposed to house the solar array. Origin Design worked with the City of Dubuque to assist Alliant Energy in securing enough area and develop lease agreements for the property.
The solar array features more than 15,000 solar panels, and is expected to produce enough energy from the sun to power over 700 homes a year. To prevent erosion on the sloping site, a pollinator-friendly prairie grass mix was selected to provide an ideal habitat to butterflies and bees.
Origin Design provided site design, structural design, construction layout, staking and material testing for the project. Prior to construction, Origin Design helped with roadway design for site access, and was involved in permit coordination with the DNR, Dubuque County and the City of Dubuque. The project included providing an environmental SPCC plan, including spill prevention, control and counter measures. Hydraulic and hydrology analysis was performed to determine the 100 year flood elevation for the stream crossing.
Origin Design worked with Alliant Energy, C.G. Schmitt and H & H Electric Co. on the project.
