I See Vibrant Urban Streets

Three years ago I did a post, Envisioning Smart Growth, that I want to make you aware of.   In that post I featured some impressive photoshop work done by a California firm, Urban Advantage:

Before
After
After

My original post has two intermediate steps between the before and after.  The firm’s website has many more examples of using photoshop to create visuals to show how streets can be improved through narrowing streets, widening sidewalks, building up to the street and so on.

I often like to visit their site to see the latest projects they have done, helping their clients all over the country to visually show how proposed changes would help streets and places mature into a more urban/walkable form.  Of the many posts I’ve done over the last five years this simple post was one of my favorites.  I have thoughts of transformations like this going through my head for every corridor in the region.

My hope is we, as a city & region, will begin to think beyond what we have today and work toward what we can have tomorrow.  This requires coming together to create a collaborative vision and implementing the zoning to ensure that future efforts build toward the vision.  I invite you to look through the many examples on their site.  The photoshop work is the easy part, I also know that streets won’t transform themselves without a strong vision.

What is wrong with this sidewalk?

October 27, 2009 Accessibility, Downtown 5 Comments

This sidewalk, heading South from Washington Ave. along the East side of 14th Street, has a number of issues.  Most notably it is too narrow.

On the positive side, the trees and parked cars make a nice buffer between the pedestrian and passing vehicles.  Since my stroke I’ve walked this sidewalk a few times and the half block you see here is harder to walk on than the previous two blocks to get to this point.  It slopes downhill slightly but that is not an issue.  The cross slope, however, makes this sidewalk very difficult to walk on.  The side to side slope is beyond allowable limits of the ADA.  To the eye you can see the slight slope.

The able-bodied would have no problem walking this sidewalk but for those of us with one leg that doesn’t work as well as the other find it a major challenge.

A Vintage Parking Garage

Downtown St. Louis has many parking garages, too many in fact.  Most are as bland as you’d expect a parking garage to be.

The curving exit ramp of the Macy’s garage at 6th & Pine (map link) is anything but bland.

One of the two Kiener Plaza garages are visible from the exit ramp of the Macy’s garage, above.

In this historic image, we see the Macy's garage in the background as the Kiener garages are built in the foreground.

It is hard to sustain a vibrant downtown with so much real estate used for car storage.  We built garages to accommodate everyone coming downtown but in the process created a downtown less attractive to visitors.

I just hope nobody gets the idea to list one on the National Register of Historic Places.  Wait, the city likes to raze historic buildings so perhaps we should get all of them on the register.  That may be the only way to reduce their numbers.

Site Analysis 101, Include Pedestrians/Cyclists

October 19, 2009 Planning & Design 3 Comments

Developers, architects, engineers and politicians in the St. Louis region must collectively assume that 100% of the population drives their own private vehicle on 100% of their daily trips.  They must, how else can you explain what passes for new development in the region? Only development that will remain more than a mile from the nearest structure need not worry about pedestrian access to the site. Anything closer than 1/4 mile should assume that some users will approach by a mode other private automobile.

One of my first classes in architecture school, in the mid-1980s, was site analysis.  I still have my text from that class; Site Analysis: Diagramming Information for Architectural Design by Edward T. White, 1983.  Note that the Americans with Disabilities Act did not become law until 1990.

“We should always remember that a site is never inert but is an ongoing set of very active networks that are intertwined in a complex relationship.”

White suggests a “consequence triangle” as “a convenient model for understanding the network of contextual causes and effects and how they relate to other aspects and issues of our project.”  The triangle includes the building, users and context.

The factors White listed to consider, collect data on, and to diagram, are:

  • Location
  • Neighborhood Context – 3-4 blocks adjacent to site, existing & projected uses
  • Size and Zoning – dimensional aspects of site, current and projected zoning trends
  • Legal
  • Natural Physical Features
  • Man-Made Features
  • Circulation – pedestrian & vehicular movement — quoted below.
  • Utilities
  • Sensory
  • Human and Cultural
  • Climate

Neighborhood Context:

Presents the immediate surroundings of the site for perhaps three to four blocks beyond the site boundary.  This may be extended further to an important factor or because of the scale of the project. Map may show existing and projected uses, buildings, zoning and any other conditions that may have an impact on our project.

Size and Zoning:

Documents all the dimensional aspects of the site including boundaries, location and dimensions of easements and present zoning classification with all its dimensional implications (setbacks, height restrictions, parking formulas, allowed uses, etc.) and buildable area (land available for the project after all setbacks have been subtracted).  Analysis should also document the present and projected zoning trends, plans by the city transportation department to widen roads (change rights of way) and any further trend that might affect our project in the future.

Circulation:

Presents all vehicular and pedestrian movement patterns on and around the site.  Data includes duration and peak loads for surrounding vehicular traffic and pedestrian movement, bus stops, site access edges, traffic generators, service truck access and intermittent traffic (parades, fire truck routes, concerts at nearby auditorium).  Traffic analysis should include future projections insofar as they can be made.

Clearly some of the above are dated — seldom do cities increase the width of the public right of way these days.  In places with modern zoning (not St. Louis), the urban site will have build-to lines rather than setbacks, minimum heights rather than maximums, bike parking requirements and so on.  The circulation part is still valid.  Vehicles include bicycles and motor scooters.  Pedestrians include the able-bodied as well as those with disabilities (physical, sight, hearing, etc).  The pedestrian part is what is so clearly overlooked by the professionals designing many recent projects.

They may say nobody walks in the area of their project yet a bus stop is on the edge of the site.  If you have a bus stop within a 1/4 mile you’ve got pedestrians. I’ve been so many places in our region where it seems like nobody walks at all but if you stick around long enough pedestrians begin to come from all directions.  They gather and shortly a bus appears, picking them up and dropping off others.  Those that just left the bus go in all directions.

It is not just about bus stops either.  Unless you are isolated in the middle of nowhere you have others around you.   Most will choose to drive to their destination but given the choice some will choose to walk (or bike). Designing places in such a way that a car is mandatory is just not how I was educated.  These concepts are freshman level but forgotten by many.   We need to remind them to consider all means of accessing sites.

South Grand: From the Gilded Age to “Great Street”

South Ground has always been a great street. In the early days it boasted a streetcar line, Tower Grove Park, an active business district, and the mansions of The Gilded Age. It left good bones for redevelopment a century later and has opened the door to a new era as a “Great Street.”

South Grand

In 2005, the East-West Gateway organization began spearheading an urban-planning movement called “Great Streets” in the St. Louis area. “Great Street” ideas hope to re-invent life in the city by taking a holistic view to neighborhood streetscapes. It is, in some ways, a backward-looking movement that hopes to bring back some of the chaotic diversity of earlier street life to modern ways of living.

It eschews our mid-century fascination with the car and focuses again on the street as home to all whether on foot, bike, bus or car. It also wants to achieve something more than integrated transportation; it wants to underline the cultural context of a neighborhood and to reflect the community’s deep historical roots in hopes of crafting a unique cultural identity to stimulate social and economic development.

Starting in early September 2009, the city of St. Louis and East-West Gateway began an experiment to demonstrate how those infrastructure changes might affect life on South Grand. They re-striped Grand from Arsenal to Utah Streets into a three-lane configuration with concrete barriers to simulate future bulb build-outs at the end of city blocks. Public meetings before, during and afterwards captured neighborhood assessments on the changes.

Tuesday October 6 was the final public meeting on the pilot project and East-West Gateway shared data from the experiment and initial designs with the community. Probably the most visible change has been the decrease in vehicle speeds through the business district. Before the three-lane experiment began, car speeds on the then four-lane road averaged 42 mph. Traffic slowed to 31-32 mph during the three-lane experiment.

The difference is palpable either on foot or in a car. More than half of the residents attending the meeting said pedestrian safety was either improved or greatly improved under the new configuration and 69% experienced street crossings as easier or safer.

The slower speeds did not result in greater congestion. Data collected during the trial show a modest 3%-4% decrease in congestion in the area and there was positive feedback from emergency services in that they were able to use the third lane, the turn lane, to quickly navigate the area during emergency calls, an improvement to fighting four lanes of traffic with no dedicated lane.

Neighborhood residents did present anecdotal evidence that some traffic had moved to neighborhood through streets to avoid South Grand. East-West Gateway representatives said they would collect more data on that as the trial period is extended.

The third major change was a reduction in street noise during the pilot. Forty-six percent of residents noted a reduced or greatly reduced level of noise and data collected confirmed a 17-decibel drop in high-end noise.

The pilot has thus proven to be a success in terms of calming traffic, reducing noise, and making the zone friendlier and safer for pedestrians. But what about enhancing the character of the neighborhood or enhanced economic activity? No data was presented by East-West Gateway and perhaps there are too many external factors like the prolonged recession to make any accurate determinations.

I can say, and this should please the street’s merchants, that 37% of the residents reported an improved or greatly improved shopping and dining experience during the “Great Streets” pilot. The slower speeds on South Grand do allow a better look at the shops and restaurants and the friendlier street atmosphere is likely to translate to more walkers and bikers dropping in to check them out.

So what’s next? The institutional recommendation will be made to continue the pilot, temporary concrete barriers and all, until construction can begin in mid-2010. In the meantime, East-West Gateway will continue to collect data and investigate outstanding issues like whether permanently closing the alleys that open on South Grand between Arsenal and Utah will work for residents, merchants and city utility crews. Design work will also continue along with the selection of materials and street trees. Also undecided is whether there will be dedicated bike lanes on a shared bike-car lane through the pilot area. Further consultation with the bicycling community is promised.

Since the proposed “Great Streets” improvements for South Grand are in the $8-$9 million range and only $3 million is available in U.S. federal stimulus funds, the vision being constructed in 2010 will be limited in scope. The budget will allow a permanent reconfiguration of the roadway to three lanes, widening of the sidewalks by three feet, building the bulbs at the end of each block to set off parking spaces from the roadway, and installation of new pedestrian crossing areas at intersections. Special attention will be paid to ADA curb cuts and bringing the project beyond code for ADA modifications. There will also be funds to plant more street trees and replace street lighting with more energy-efficient and effective fixtures.

An effort is being made in the design process to incorporate established neighborhood design icons into the new designs for bike racks, benches, newspaper box corrals, and neighborhood signage. Picking up the wrought-iron, Gilded Age designs from the fencing on either side of the Tower Grove garden gates and the neighborhood signs for Compton Heights and Tower Grove East, the new amenities will reinforce the neighborhood’s unique design heritage.
Compton Heights

Several issues remain up in the air. Two local schools founded in the Gilded Age, Gallaudet School for the Deaf and the Missouri School for the Blind, have requested that audible signals be added to traffic lights so their students can safely cross at the South Grand business-district intersections. Green, LEED-standard materials for paving options, bioswales to deal with street water run-off, and lighting fixtures that meet requirements for night-sky preservation are all under consideration, but haven’t been locked down.

To the extent that this project succeeds, credit should be given to the credible public-engagement process for this project.  Two initial workshops were used to identify problems in the area in 2007 and 2008; three extensive public open houses were held in August, September and October to determine design options, establish neighborhood preferences, and provide data from the pilot. Extensive displays, multiple meeting times and venues, printed materials, online surveys, and extended live question-and-answer sessions with keycard voting on options were all used to present ideas and receive feedback. At Tuesday’s meeting, 85% of residents found the process to be transparent and 74% felt the most important problems on South Grand had been addressed.

Project planners had a few surprises. One was the support expressed at public meetings to not just meet, but exceed, current ADA standards for access to the area as a business and social hub. Two was the public preference for LEED-compliant materials for paving, including pervious pavement. And three was support for street lighting that would meet neighborhood needs for safety, yet not be overly lit, so the area could meet improved energy efficiency standards and protect the night skies from unnecessary light pollution.
