Construction on a high-profile downtown Des Moines parking ramp project will be delayed because changes to skywalks and elevators have led to an inability to secure construction permits in time to meet the original deadline.

As a result, the Des Moines City Council will be asked Monday to amend a development agreement with Mandelbaum Properties, developers of an 11-story, 690-stall parking ramp along Fifth Street between Court Avenue and Walnut Street as well as a mixed-use building and residential high-rise.

Under the amendment, construction on the $45 million parking garage, the first phase of a three-part $170 million project, has been moved to July 23 from April 30, with the completion date moved to May 22, 2020, from February 2020, said Carrie Kruse, economic development coordinator for the city.

The amendment does not affect later deadlines for a mixed-use building with offices over a movie theater that will front Court and a 39-story tower that will front Walnut, she said. 

Though demolition of the old Fifth and Walnut parking ramp is complete, crews remain onsite to dig out old building foundations, Kruse said.

Earlier this month, the City Council approved retaining the Davis Brown Law Firm and attorney Robert Douglas of the firm to represent the city’s interest under a condominium regime that was established for the development.

Under the agreement with Mandelbaum Properties, the city can take possession of various elements of the development if deadlines are not met. In addition, because each of the three elements of the project — parking garage, residential tower and mixed-use building — intersect at various points, the city wants to make sure its underwriting of the parking garage is not used in financing of the tower and mixed-use building, Kruse said.

Douglas and the law firm were retained at the hourly rate of $295.
