Principal Riverwalk – What $75 Million Will Get You


Announced in July 2004, as part of one of downtown’s largest employer’s 125th anniversary celebration, the Principal Riverwalk would be one of the largest downtown transformations that the city has seen. It’s now more than four years later and I thought it would be appropriate for an overview of what was planned and what has been delivered since then.

With an opening cost projection of around $26 million, a ground breaking ceremony for Phase I took place on July 22nd, 2004. Principal would originally donate $10 million with the rest to be raised through community, civic and state monies. At that time, it was purposed that later phases may incorporate a half million dollar skate park and white water rapids courses.

By March 2005, costs estimates were more than double, now a total cost was being estimated around $55 million due to some additions to the original plan such as upgrading the Meredith Trail connector to Gray’s Lake and upgrading Principal Park to include a plaza with fountains right outside the park. Also the Hansen Company Triangle was being added to the mix.

By end of 2006, cost estimates were now totaling close to $74 million almost three times what the original cost estimate was in 2004. As 2006 drew to close, five projects had been completed totaling $15 million. The Brenton Skating Plaza, cost $4.5 million, more than double the original estimate. The Union Railroad Bridge that opened in July cost $4.5 million – $2 million more than expected.

The largest aspect of the Riverwalk project yet to be completed is the Center Street pedestrian bridge. Construction began on the site Aug. 15, with an expected completion date of late next year.

The bridge will be 400 feet long and feature 100-foot-tall arches. This bridge will be much bigger than the blue arched bridge on Interstate 235, which is only 280 feet long.

The Center Street Bridge originally was sited directly above the Center Street Dam, but will be built slightly upstream instead. The shift will make construction simpler and allow better access for any future work on the dam. It also cuts costs by shortening the span.

All riverwalk projects for Phase I should be completed by year-end 2009. I can’t wait to see it all done. This will make downtown living even more appealing.

Building Spotlight: Downtown Des Moines Public Library


I think one of the coolest looking buildings downtown right now is the Des Moines Public Library building located on the eastern edge of the Western Gateway Park at 1000 Grand Avenue. This building is gorgeous both during the day when the bright sun is shining on it and fascinating to look at during the evening hours when it’s all lit from inside.

For a mere $32 million, the City of Des Moines, had a famous British architect, David Chipperfield design and build us a 140,000 square feet structure. The building also sports green roof construction, a first of its kind for the City of Des Moines. The function of the Green Roof Infrastructure provides many benefits to the building and the surrounding community as well as the beauty it brings.

The building appears windowless but turns out to have a plethora of full-height glazed surfaces. Triple glazing with an integrated copper mesh enables this optical illusion to occur. During the day, the façade seems opaque and glows with a warm, coppery colour. At night, when interior lights are on, the façade becomes transparent. This transparency allows the people on the inside of the library feel as if they are actually outside in a park.

If you look at the library from above, it resembles an airplane with the wings of the building meeting each other at broad angles. Reports show that the idea behind this shape was for the building to embrace its green surroundings and to create sheltered areas or ‘pocket parks’ between the wings.

Viewing Downtown Des Moines Even Better


Last month I wrote a post on Des Moines finally making it on Google’s Street View tool. Why Google’s Street View is very cool, it could get even cooler. It was published today that a new satellite has been launched into space will provide Google with even more unprecedented resolution.

It’s a joint venture between a commercial satellite imaging provider and the Department of Defense. In return for undisclosed terms, Google got two considerations: its logo on the side of the launch vehicle, and exclusive use of the mapping images that the satellite produces. The new satellite hardware is a significant improvement over previous generations. Its camera drops the resolution of images down from a meter to half that figure—apparently, the hardware goes down to 0.41m.

Until Google publishes pictures from that new satellite, here’s a new tool added to our Downtown Maps page that allows you to see downtown three different ways simultaneously:

  1. With Google Street View
  2. With Google Street Maps View
  3. With Microsoft’s Bird’s Eye View

A full screen version of the tool is more fun to play with and is available as a link under the tool. Please just don’t use these tools on your mobile device while driving, as this post’s picture shows what can happen.

Experience Downtown Architecture


So this evening I finally made it to one of the Architecture @ Hand Walking Tours. I did the North tour and had a great time learning about some of the buildings that I walk by everyday. The architectural details that my guide pointed out are things I have totally missed, but now will notice again and again on my walks through downtown. I never knew so many famous architects have designed buildings in our downtown and that we had so many different styles of architecture for a city our size. Now, I can’t wait till next summer when I can do the West, East and the new South tour. I would highly recommend these tours to anyone, it will help you experience downtown in a new and different way.

One of my favorite buildings, the Ruan Building, was completed in 1975, and stands 460 feet tall with 36 floors. It’s the second tallest building in Iowa. The outside is made out of Cor-Ten steel, which is an alloy designed to withstand the weather and require no maintenance (cleaning or painting). The building was supposed to weather to a rich red-brown color, but due to the cleaner atmosphere here, never quite made it to that color. I learned that the streaking on the building came from the window caulking that was used melting and running down the side of the building. A lot of people here thought the building was a big rust bucket, but beauty is in the eye of the beholder and I love the look of it.

From the Iowa Public Television site, I found this list of the 50 most significant Iowa Buildings
of the 20th Century as selected by the AIA-Iowa Chapter. The majority of these buildings are in downtown Des Moines. Dates listed here are completion dates.
* Designates building of the decade.
** Designates building of the century (which is also building of its decade.)

Out With the Old, In With the New


It looks like over the last few weeks construction has really started up on the new Wellmark Blue Cross Blue Shield company headquarters building. As a downtown resident this brings hope and anticipation with new construction that continues to bring vitalization to our downtown, but the same time begs the question what’s going to happen to all the current leased spaces that these companies occupied? With Wellmark moving out of the Ruan and Davis Brown Law Firm moving out of the Financial Center, who will move to occupy those large spaces?

Wellmark’s new five-story, 550,000 square feet building, on 6.5 acres will be a huge addition to downtown. The building beautiful architecture will look awesome sitting across from Western Gateway Park the new Pappajohn Sculpture Garden. Here’s a video that shows off the beautiful architecture of the building:

Downtown Walking Tours


Summer is almost over and I’m mad at myself for never finding the time to do the Architecture @ Hand Walking Tour. There’s only one more date left for this year, Thursday September 4th. I’m going try my best not to miss it. The Iowa Architectural Foundation offers these walking tours as a unique approach to getting to know downtown Des Moines by learning fun facts about both old and new downtown buildings.

The walking tours are led by local architects and there are three different tours to choose from: North, West and the East Village tour. The tours begin at 5:30pm and Nollen Plaza (corner of 3rd and Locust, across from the Civic Center). The tours are typical 90 minutes long and they recommend everyone to wear comfortable walking shoes. There is a $10 per person suggested donation to benefit the educational programs of the Iowa Architectural Foundation. The foundation’s goal is promote the awareness of the contribution of architecture and community design to the quality of life in Iowa since 1989.

In doing some research for this post, I found a link for some great old postcard shots of Des Moines.
