Following who is in charge of what among the plans for the Arch grounds revitalization has been tougher than keeping your eyes on the baseball under the caps on the big screen at Busch Stadium after a couple 30oz Budweisers. In short, the National Park Service (NPS) has said thanks, but no thanks on comments regarding I-70 and other elements (all beyond the park boundary). MoDOT has said they're serving their client, the City of St. Louis and that alternatives do not meet the goals of CityArchRiver. The City says that the CityArchRiver2015 Foundation is at the design controls. CityArchRiver doesn't say much. (There's a nice (snarky) Venn diagram at the end to illustrate how this works.)

This byzantine morass prevents any holistic discussion of the project by the public. And so here we focus on the NPS Environmental Assessment for Implementing CityArchRiver Initiative Elements. As a federal agency, the NPS is required to publish for public comment changes being considered to the Arch grounds. One alternative is required to be "no action". Taken in this context, the maximum change option outlined below should be sought by the NPS in nearly all aspects of the project.

The depth of existing challenges and need for substantial investment in the Arch grounds has be obvious for many years. In fact, the park has been substantially neglected and underdeveloped since, well since it was conceived of nearing a century ago. The NPS failed to update the park's General Management Plan for decades. CityArchRiver, and the city, eventually stepped in to force change. The options considered by the NPS below are designed by Michael Van Valkenburgh and Associates, the winners of the Framing a Modern Masterpiece competition.

The options being considered by the National Park Service:

West Gateway: The "lid" is happening as a MoDOT project. Should Smith Square be expanded and re-invisioned? Should a new west-facing museum entrance be built into the existing berm east of I-70?

The Visitor Center/Museum: Should the existing facility be renovated and updated? Should it be expanded by 35,000-50,000 square feet and ticketing/ingress be moved to a new west-facing entrance while existing access at north and south legs be exclusively for egress?

West Gateway
{the West Gateway and Museum minimum (left) and maximum (right) alternatives}

North Gateway: Washington Avenue east of I-70 will not be accessible from Washington Avenue west of I-70 as a result of the MoDOT project. Should the existing parking garage be retained? Should aesthetic changes be made to the garage? Should the garage be demolished and replaced with a "discovery garden" after a holistic parking strategy for the Arch grounds is implemented?

North Gateway
{the North Gateway minimum (top) and maximum (bottom) alternatives}

East Slopes: Should they remain as they are today? Should two winding accessible paths be built adjacent to the grand staircase? In addition, should two winding accessible paths be built near the north and south flood walls?

North_South Slopes

Reflecting Ponds: Should they be left as is? Should mowed grass accessible paths be added? Should storm water swales and new runoff management system be installed?

Processional Walks: Should existing walks be maintained and ash trees replaced? Should subsurface soil conditions, irrigation and drainage systems be improved and replaced? Should the aggregate surface be replaced?

Old Courthouse: Should the courthouse remain unchanged? Should galleries be renovated and expanded on the first and second floors, surrounding streetscape improved and accessibility added?

Central Riverfront: Should Wharf Street be raised from Chouteau Avenue to Biddle Street? Should a two-way bike path be added and the street narrowed? Should a raised pedestrian crossing and bus drop-off/pick-up lanes be added?

Wharf Street

Security: Should a continuous secure perimeter of bollards be installed with visitor screening remaining at north and south entrances? Should a shared bicycle path serve as perimeter security at the North Gateway and visitor screening take place at a new west-facing entrance?

Accessibility: Should selective re-grading and secondary paths be added? Should north and south entrances and the Old Courthouse see accessibility enhancements? Should an elevated accessible walkway be added at the North Gateway? Should an accessible path be added to the previous Washington Avenue area? A new west-facing museum entrance would be accessible.

Topography and Grading: Should Smith Square be re-graded? Should the northwest corner be re-graded to improve accessibility? Should the berm be altered for a new museum entrance, the North Gateway re-graded after demolition of the parking garage and explorer's garden and additional paths be added?

{project overview showing moderate (left) and maximum (right) re-grading alternatives}

Parking: Should the north garage be maintained? Should the garage be demolished after a holistic parking strategy for the Arch grounds is implemented?

Planting: Should this remain unchanged? Should plantings follow the original intent, be compatible with the historic landscape and use sustainable management practices? Should additional plantings that do not interfere with sightlines be added? Should new plantings be introduced at a west-facing museum entrance and a North Gateway discovery garden?

{project overview showing moderate (left) and maximum (right) alternatives}

So which alternatives should the NPS support? West Gateway: with the “lid” a fait accompli, a new western museum entrance makes a lot of sense. It would make sense without the lid as well, but a lid without a new entrance would be a missed opportunity. The Visitor Center/Museum: with a new entrance this would be expanded. Updating displays and programming would be great. East Slopes: add the four winding paths. Reflecting Ponds and Processional Walks: fix them. Old Courthouse: go big. Central Riverfront: raise it and implement multi-use strategy. Security: whatever works. Accessibility: more is better. Topography and Grading: whatever works. Planting: sure.

That was easy. Of course, parking and the north gateway aren’t so easy. The challenge is that the space occupied by the existing garage is the one place the NPS will allow dramatic change. The discovery garden and additional paths could be exciting. However, they come at a great cost and the case for more parkland isn’t clear. But again, within the context of the MoDOT plans, the north parking garage might as well go. Washington Avenue will become a “slip lane” off of an I-70 exit ramp. The public can comment via this online form until March 1, 2013. The NPS will hold a public open house on January 29, 2013 from 4:00-7:00 p.m. at the Old Courthouse downtown. For what it’s worth, the only program that makes sense for the NPS is the “Maximum Change” alternative.

    Topic Question 1: In regards to all improvements to accessibility, paths, walks, and to the Wharf Street improvements: these should be the top priority. The Arch is already a destination, it’s just too inaccessible to shine. In a similar fashion, improving Wharf Street and the Arch-to-riverfront connections and views will enhance the Arch itself. People love riverfronts, and will visit ones that aren’t inaccessible and ugly.

    Comments: The Arch would be well-served if the NPS advocated for other governmental entities to remove I-70 from downtown St. Louis. Instead of over-engineering a grand accessibility solution that in reality only improves 3 east-west streets, a removed I-70 would open the the Arch up to be connected to pedestrians and sight lines for the entire street grid of Popular Street up to Washington Avenue.

    Tear down a garage to build another one somewhere else makes no sense. Surely some modification could be made to improve the connection to the landing without complete removal perhaps just reclaiming the top of the garage as a grass field and leaving the rest underground. The place where there is too much parking is in The Landing itself. Cover the stupid surface lots with infill. doing this should improve usage of the Arch Garage which is PAID FOR.

    “Byzantine Morass”. Nailed it right there. Venn diagram is spot on. In Washington and Jeff City, everyone wants to hold hearings and investigations and hearings on government problems. St. Louis needs to hold its own hearings on why things around here are so inefficient, crowd alienating, and…well, byzantine. Perhaps the best outcome of this whole Arch efforts will be how it has shined a spotlight on the impossible world of planning, leadership, and governance we face here in St. Louis (and in many other communities around the country).

    The planter at Lenor K Sullivan is beyond horrible, especially if it is still continuous as previously shown. Not only are they creating an additional barrier between the Arch Grounds and the river (WHY?), but the view of the river from cars will be mostly blocked. Isn’t the entire point to create better connections to the river, both physical and visual? The incompetence of whoever designed that is simply mind boggling. Lower it to 18″ and turn it into a bench so people can stop and, you know, actually appreciate the river. It’s an absolutely terrible idea.

    On the flip side, the newly created accessible paths on the north and south slopes are a fantastic idea. I still wonder how the top of the levee gets used. Have always felt like they are such a wasted opportunity.

    The lid is still one of the stupidest thing I’ve ever heard. Get rid of the lid, build the new West entrance, keep the garage, raise Leonor K Sullivan, rest of the stuff is whatever.

    This city needs a plan. I noticed a “2050 Vision” proposal on RallySTL. St. Louis really needs to get one of these.
