Boca Raton, Fla.-based CSL Plasma Inc. plans to open a new blood-plasma collection center on north Monroe Street after it completes a $1.2 million renovation project there, according to predevelopment documents filed with the city of Spokane.

The center would be located at 2126 N. Monroe on the former Casey's Restaurant site.

A call to CSL Plasma was referred to a corporate spokesman in Boca Raton, who couldn't be reached for comment.

Predevelopment is an optional preliminary stage of the planning process designed to identify potential obstacles to a proposed project before the applicant files for land-use and building permits.

As proposed, CSL would renovate the 10,000-square-foot building and add a 1,000-square-foot shipping-and-receiving area, preliminary plans say. The scope of the renovation work would include demolishing the basement, replacing the roof, and cleaning and painting the exterior.

The awning in the front of the building, at the southeast corner of Monroe Street and Mansfield Avenue, would be removed, and a new entry vestibule would be constructed with an arched canopy, a description of the proposed project says. Site work would include replacing the sidewalk with a ramp and railings to meet accessibility requirements, the description says.

The Spokane office of Mt. Pleasant, N.C.-based Novus Architects, is designing the project, and Hahn Engineering Inc., of Spokane, is the consulting engineer. A contractor hasn't been named yet.

CSL Plasma operates more than 60 collection centers throughout the U.S., its website says, including Spokane-area centers located at 104 W. Third downtown and at 9621 E. Sprague in Spokane Valley.

Plasma, the straw-colored liquid portion of blood, contains proteins and antibodies and plays a role in a number of vital functions that control bleeding and fight infection. Plasma is a key component of products used to treat hemophilia, shock, immune deficiencies, and other blood disorders, CSL's website says.

CSL Plasma collects blood plasma from donors through a process that separates the plasma and returns the red, cellular portion of the blood to the donor's bloodstream. Donors can give plasma up to twice a week and can receive up to $300 a month for it, the website says.
