Work To Begin On Boat Landing At Rock Island's Schwiebert Park

Updated:

The Landing at Schwiebert Park is a 23 slip transient marina to be constructed under a $1.5 million Boater Infrastructure Grant from the US Fish and Wildlife Service, plus local downtown TIF funding. 

The Boater Infrastructure Grant (BIG-P) program is a federally administrated program, initiated by the boating community and funded through boater user fees with grants from the Sport Fish Restoration and Boating Trust Fund.

The transient marina is designed to provide boating destinations and infrastructure for boats 26 feet or longer, and to spur economic activity in the downtown Rock Island area.

The marina is located at the downstream outlet of Sylvan Slough, in an area close to Schwiebert Park. 

A marina was originally conceived as part of the park project, and serves as a point of interest and an anchor for river activities on the eastern end of the park. 

In accordance with state and federal regulations, a mussel survey was completed during 2011 to identify the types and density of mussels. 

No federally listed threatened species were found during the survey, but a few specimens of an Illinois Threatened species called Black Sandshell were found. 

The marina is designed to have minimal impact on mussels, which were harvested to the verge of extinction in the early 20th century for uses such as the pearl button industry in Muscatine. 

Mussels have since recovered in numbers, particularly shallow protected waters such as Sylvan Slough. 

Fourteen 8- and 12-inch diameter steel piles will support the marina, which will float up and down with the river as a year-round fixture of the Rock Island riverfront. 

Due to the near surface rock of the Mississippi River that gives Rock Island its name, the pilings will be augered into the riverbed and grouted permanently in place with concrete. 

The river will flow through and around the pilings and the dock will float at river level.

This approach occupies a much smaller part of the riverbed compared to marina alternatives such as a rubble mound breakwater, which involves placement of large amounts of fill in the river. 

The piling approach is unique in this section of the river, allowing both marina and mussels to co-exist nearby.

Helms and Associates of Bellevue, Iowa will conduct the mussel relocation during the week of August 5-9, 2013.  Mussels will be moved from an area five feet in diameter near each pile.

Piles will be field located and driven by Newt Marine of Dubuque, working for General Contractor Valley Construction. 

Helms and Associates employs biologists and commercial divers to collect impacted mussels, and then relocate the mussels to an upstream location in Sylvan Slough.

Construction of the marina is expected to be completed in the fall of 2013, with an opening for boater use in the spring of 2014. 

The Landing at Schwiebert Park was designed for the City of Rock Island by a team led by Stanley Consultants of Muscatine. 

Architectural services were provided by Gere-Dismer Architects of Rock Island.

Landscape Architecture services were by SAA Design Group of Madison, Wisconsin. 

Marina consultant was Lunde-Williams also of Madison. 

The design team was also responsible for Schwiebert Riverfront Park, which opened in the summer of 2010.
