’13 City of Okoboji Low Impact Development/Drainage Improvements
Beck Engineering, Inc. was hired by the City of Okoboji to design improvements to five waterways in the city that flow directly into West Okoboji Lake. These drainage ways are very wooded with steep side slopes and minimal vegetation growing. The drainage ways lost approximately 2” of soil each year prior to construction of the Low Impact Development Improvements. The waterways also allowed silt, sediment, anti-freezes, oils, and other contaminants to reach West Okoboji Lake without being cooled, filtered, or treated. The project involved construction of 10 bioretention cells and overflow storm sewer/intakes to alleviate the problem. The project was substantially completed during the 2013 construction season and had a project cost of approximately $400,000.
Historic Arnold’s Park Parking Lot Retrofit
This project was completed in the spring of 2005 and involved construction of 5 bioretention cells, a pervious concrete parking area, and a pervious concrete driveway. Prior to construction of these Low Impact Development features, the 3 acre asphalt parking lot drained directly to an open-throat intake on the northwest portion of this property and the stormwater runoff flowed directly to West Okoboji Lake. Now, over 90% of the stormwater runoff in an average year is cooled, treated, filtered, and slowed down by the bioretention cells and pervious concrete chambers prior to flowing to West Okoboji Lake. The brown plumes in West Okoboji Lake that used to be seen at the outlet of the storm sewer during rainfall events has been replaced by clear water exiting out of the storm sewer. This project was the first LID project in the area and received a Nomination for Outstanding Performance for Innovative Design of Stormwater Management Practices that Facilitate Improvement in Stormwater Quality at the 2007 Iowa Stormwater Conference.
City of Okoboji PCC Paving/Low Impact Devlopment Project
This project was completed in 2007 and was the first total environmental retrofit of an existing neighborhood in the State of Iowa. The retrofit was for Nichols Avenue, Tarzan Street, Park View Avenue, Hollingsworth Street, and Echo Bay Avenue north of The Inn in Okoboji. The project involved a total reconstruction of over 3600 feet of street, construction of 15 Bioretention Cells, and 3 Stabili-Grid rock chamber parking areas. Approximately 20 easements were obtained from property owners for construction of the LID principles. The project was challenging due to narrow right-of-way widths, the need for easements on private property, and constructing the project through an existing neighborhood. The project was successfully staged to provide minimal disruption to adjacent homeowners. This project received an Award for Excellence for the Innovative Design of Stormwater Management Practices used in Local Projects at the 2008 Iowa Stormwater Conference.
Lakes Regional Healthcare/City of Spirit Lake Zenith Avenue Re-alignment Project
This project was designed in 2012 and built in 2013. The project involved the re-alignment of Zenith Avenue, construction of new sidewalks, and construction of a new storm sewer system south of 23rd Street in the City of Spirit Lake. The project also involved construction of two new parking lots, a new entrance, bioretention cells, permeable pavers, and a pocket wetland on Lakes Regional Healthcare Project. The Low Impact Development improvements were partially funded through a clean water grant. The project partners included Lakes Regional Healthcare, the Dickinson County Clean Water Alliance, and the City of Spirit Lake. The project led to the City of Spirit Lake receiving an award for Outstanding Performance Related to Protecting and Improving Urban Water Quality at the 2015 Iowa Stormwater Conference.
Spirit Lake Community Schools Track & Activities Field Construction Project
This project was designed and constructed in 2011 and involved construction of a new all-weather track surface, new bleachers, new lights, new retaining walls, sidewalk, and field turf. The project was funded partially by the Spirit Lake Community School District and partially through community donors. The project received the Athletic Use Paving Award from the Asphalt Paving Association of Iowa and from the National Asphalt Paving Association for the Spirit Lake High School Track/Field Turf Project in 2011. The project had a construction value of approximately $2 million.
City of Spirit Lake East Entryway Project
This project was completed in 2004 and consisted of construction of approximately 1/2 mile of 10′ wide concrete recreational trail, two brick paver sitting areas, and two permanent fishing piers. The project was jointly funded by the City of Spirit Lake and the Iowa Department of Natural Resources. The project won the Award of Excellence from the Iowa Concrete Paving Association for Iowa’s Best Recreational Trail PCC Paving Project in 2004.
Wahpeton Highway 86 Recreational Trail Project
This project was designed in 2006 and constructed in 2007. The project was a joint effort between the City of Wahpeton, the Dickinson County Trails Board, and the Iowa Department of Transportation. Improvements included construction of a 1 mile concrete recreational trail along the east right-of-way of Highway 86 from 180th Street to 190th Street. This section of recreational trail was vital to provide a safe access for pedestrians and bicyclists to travel from the south portion of Wahpeton to the north portion of Wahpeton. Prior to construction of this recreational trail, pedestrians and bicyclists had to travel on Highway 86, a heavily traveled bypass around the Iowa Great Lakes Area. The project won the Award of Excellence from the Iowa Concrete Paving Association for Iowa’s Best Recreational Trail PCC Paving Project in 2008.
City of Lake Park South 2nd Street Bridge over Silver Lake Dam Spillway
This project was completed in 2008 and consisted of the construction of a new bridge on South 2nd Street over the Silver Lake Dam Spillway in the City of Lake Park. Beck Engineering, Inc. completed all of the construction survey for the project. The project won the Iowa Quality Initiative Structures Award for being rated the best Culvert on a Local Road System constructed in the State of Iowa in 2008-2010.
