A closer look at Des Moines' plan to upgrade Principal Park

Here are some ideas outlined in a preliminary plan to upgrade Des Moines' Principal Park.

• It's expected to go before the City Council Nov. 15.

Main entry: A redesign would focus the left field corner of the stadium as the key entry point and include a year-round events plaza and a merchandise store.

Parking garage: A three-story, 750-vehicle facility constructed near the corner of Southwest 3rd Street and Line Drive that is currently a ground parking location.

• Restaurants and bars would flank the 2nd Street side of the development.

Mezzanine Club: Upgrades to the upper concourse area behind home plate that the master plan says is currently underutilized.

• An operable glass wall system, a kitchen and restrooms would accommodate about 250 people.

Mezzanine suites: A two-story area above the main concourse would create two additional areas for eight new suites.

• Party decks with room for about 100 people could be at both ends of the existing suite level.

Downtown playground: Located just off the bike trail on the park's southwest side with a river overview.

Interactive water feature: A splash pad near the confluence of the Des Moines and Raccoon rivers at the park's southeast side.

• Park space and art sculptures would be in adjacent areas.
