The city of Des Moines will have a solar array that will supply all of the electrical needs of a $19 million parking ramp that will be part of an estimated $60 million residential and commercial development on a city-owned parking lot bordered by Robert D. Ray Drive, East Third Street, Locust Street and Grand Avenue.

Construction of the six-level, 535-stall ramp is expected to begin this spring and should be completed by the second or third quarter of 2017.

The parking ramp is part of a larger development plan brought to the city by a development team of Jake Christensen, Tim Rypma and Jim Cownie. On the city lot, plans call for eventual construction of two buildings that would flank the parking ramp on the north and south. A mix of retail and residential or office space is planned for a building along East Grand and a retail and office building is planned along East Locust. The buildings would be a minimum of four stories, according to a report from Erin Olson-Douglas, an urban designer in the city's Economic Development Department.

The city will retain a parcel fronting Robert D. Ray Drive for the possible future development of a civic building.

The development team, operating as 101 East Grand Parking LLC, will acquire the parcels flanking the ramp under a development and financial agreement with the city that calls for tax increment financing at 70 percent for eight years, 60 percent for the next two years and 50 percent for the final five years of the agreement. The financial package, which was approved today by the city's Urban Design Review Board, also includes a rebate of the cost of acquiring the two parcels and could include residential tax abatements.

The same developers also plan a $27 million residential and commercial development nearby at 219 E. Grand. The financial package for that project consists of 100 percent tax increment financing for 10 years, followed by 50 percent for the next five years.

That project calls for 17,000 square feet of ground-floor retail and restaurant space, with 98 apartments on the upper floors.

Residents and visitors to that project will be able to use the city-owned parking ramp.
