Rebuilding Place in the Urban Space

"A community’s physical form, rather than its land uses, is its most intrinsic and enduring characteristic." [Katz, EPA] This blog focuses on place and placemaking and all that makes it work--historic preservation, urban design, transportation, asset-based community development, arts & cultural development, commercial district revitalization, tourism & destination development, and quality of life advocacy--along with doses of civic engagement and good governance watchdogging.

Extending the "Signature Streets" concept to "Signature Streets and Spaces"

=============
Updated:

Republished on Saturday September 5th, from Friday September 4th, because I significantly revised the sections starting with "Additions/Sustainable Mobility Platform"
=============


There is an article in the Cleveland Plain Dealer ("Lakewood plans all-purpose trail, streetscaping and public art for Detroit/Sloane intersection") about the City of Lakewood planning to make urban design and placemaking upgrades to a particular intersection which because it is across a bridge from Cleveland, is an inadvertent gateway to the city.

The article mentions they recognize the importance of making it a gateway to the city, will add a trail connection to a nearby Metropark, include public art, etc.

And yesterday, driving down a huge road in Salt Lake County, 5400 South, which has at least 3 lanes in each direction plus some reversible lanes in the middle, I saw three little urban design elements on what is otherwise a wide expanse of concrete: (1) signage on the Bangerter Highway overpass, identifying it; (2) a small section of plantings in one area, probably done by the City of Kearns; and (3) a sign far too small to read saying something about a parkway.

So I am reminded that it's worth revisiting the "Signature Streets" concept I came up with in 2010, at the very end of the development process for the Western County Pedestrian and Bicycle Access Plan,

The basic idea was built upon the realization that the set of primary arterials in a community is the foundation of its mobility network and the aesthetic qualities, positive or negative, shape the perceptions of the community.

I didn't have time to fully develop it or sell it to the advisory committee, who couldn't grapple with it as a concept different from the competing "Complete Streets" program.  The difference is that Signature Streets aims for a bigger scale and platform and packages broader identity systems and funding mechanisms.

Still, a couple elements made it into the plan, including a zoning change that recommended putting parking behind buildings on arterials where normally the parking is in front of the buildings.

Then I went on vacation.  After coming back, I came across a presentation by David Barth and Carlos Perez, then both at Glatting Jackson/AECOM, which included a diagram that perfectly expressed my thinking about what I called Signature Streets, which was, as they called it "The Public Realm as an Interconnected System."

Although "Linkages" don't appear to be co-equal in the display within the graphic, and in the Signature Streets concept they are.  My graphic idea was each mode would be rendered like a NYC subway map, side by side by in different colors for each mode--walking, biking, and transit.

The reality is that designs for most arterials do not prioritize aesthetic or place considerations.  Note that the "parkway" road type, typical of the 1920s and 1930s is an exception.

The challenge is to balance mobility, commercial, and aesthetic-place priorities in street design, in a land use and transportation planning paradigm that focuses mostly on prioritizing traffic throughput.

Other influences.  One resource is the Smart Transportation Guidebook, produced by the Delaware Valley Regional Planning Commission.  It's in need of an update, especially wrt biking.  But it was pioneering in terms of providing a framework for matching mobility infrastructure to land use context, rather than building all roads to support traffic moving at freeway speeds.

Since this was published in 2008, many more communities have come up with more detailed and expanded guidance on what can be done.

Some examples include San Francisco's Livable Streets program and the new Street and Intersections Design Typologies proposed by Salt Lake City.

Not only does the SLC guide overtly include intersections as an element to be planned for in special ways, it formally expands the definition of the functions of the street right of way in two ways.  First, it includes "person mobility" as equal to automobile movement and throughput -- this isn't a new concept, which focuses on throughput of people overall, making the point that single occupant automobiles are inefficient.


Second, it dentifies greening and placemaking as functions that should be planned for and integrated within projects.

The Signature Street idea.  The concept was sparked by all the various meetings I had with other agencies, our public planning meetings, smaller meetings with stakeholders and community groups, research and writing for the plan, exploring funding mechanisms, etc., but probably what touched it off was a meeting in January with citizens requesting desired design improvements on one arterial that was also neighborhood serving, and actually under the jurisdiction of the County Department of Public Works--whereas most high volume arterials are under the control of the State Highway Administration (which is true for all such roads across the state--SHA runs them, not the local jurisdiction).

It wasn't til mid-June when all this combined into "Signature Streets" where based on what I call action planning ("Best practice bicycle planning for suburban settings using the "action planning" method") about integrating program delivery and branding and identity systems into planning processes using the design method, I realized the "hook" in selling improvements as an integrated program should be out of the recognition that the road network is the primary way in which a community's identity is shaped.

And that this can be done both by acknowledging the aesthetic qualities of the road network by using urban design principles and by reconceptualizing the road network as a (sustainable) mobility network, thereby incorporating walking, biking and transit users alongside but equal to motor vehicle users.

Signature Street Model

(1)  combine complete streets principles and the concept of defining roadway characteristics, roadside characteristics, and desired operating speed of traffic according to land use context as discussed in the Smart Transportation Guidebook

(2)  with smart growth ideas focusing investment on existing places

(3)  along with the integrated public realm concepts of David Barth

(4)  by designating a subset of a community's road network as foundational or "signature"

(5)  and upgrading these streets with systematic special and complete treatment so that sustainable transportation modes (walking, biking, and transit) are integrated into the mobility system (also related is an earlier Barth approach, that streets should be treated as linear parks), along with streetscape improvements (the County already has an excellent streetscape improvement program, just not a focus on sustainable transportation) so that the streets also are a means for strengthening quality of life and "placemaking" for neighborhoods and districts they serve most directly.

This should include public art, special crosswalk and intersection treatments, and the integration of improvements to adjacent public spaces more generally.

The county's streetscape program was focused on commercial districts, but could be extended to include areas around cultural and other civic assets, etc.

One expression of branding and identity systems would be street sign toppers to denote the Signature Streets within the county road network  Toronto has an extensive program using "sign toppers" to display place-based identity elements.

(6) while incorporating a specific branding and identity system for "Signature Streets" within the transportation network and the broader network of civic assets in part as a marketing tool.

Utah's Legacy Parkway (State Road 67) has a logo, which is used in various signage along the route.

(I also proposed created a common identity and branding signage system for the county's civic assets like libraries and parks.)

(7)  with all of these elements in combination to support the case for financing using bonds and winning the vote in favor of the bond referendum, therefore raising the funds to pay for the development and enhancement of the upgraded mobility network and acquisition of the necessary right of way.

Funding is key.  In most communities (not DC), to expand the right of way, you have to buy the land.  That's expensive.  The government doesn't want to do it.

But by positioning "Signature Streets" in terms of extending and enhancing the road system by adding elements that build a more complete mobility network that enhances quality of life and making the argument that the county's residents "deserve" a mobility system that meets 21st Century needs, and in keeping with the fact that the County is the third largest jurisdiction in the State of Maryland makes this kind of re-thinking achievable.

Parks bond votes almost always win.  With regard to bond funding, even in bad times, parks-related bond initiatives pass overwhelming in Baltimore County.  And this idea of making roadways a type of "linear park" increases the likelihood of a successful referendum.

The model that I suggested was Seattle's Bridging the Gap initiative (it's now called Move Seattle).  Another example which I learned about later is the "Metropolitan Area Projects program in Oklahoma City, which is a capital improvement program focused on delivering transformational projects, funded by a sales tax surcharge.

Additions/Sustainable Mobility Platform

In terms of additions or expansions of the original post, probably the way to do it is to stick with the 7 points, and have appendices for each of the points with more detail.

One way to approach thinking about the mobility elements is using the Sustainable Mobility Platform Framework.  It needs another iteration of codification, but it aims to provide thorough coverage of the options within each mode.

While center cities tend to have more infrastructure that supports sustainable modes, suburbs are often in the position of being placeless -- what author James Howard Kunstler called The Geography of Nowhere -- because the car-centric sprawl land use and transportation planning paradigm didn't prioritize place and centers.

So today many suburban communities have to re/build central places to define their communities and create placemaking opportunities.

-- Ten Principles for Reinventing America's Suburban Strips, Urban Land Institute
-- CENTER POINT Master Plan: Vision Document and Small Area Plan, Taylorsville, Utah

The Taylorsville Plan for recreating an city center out of unconnected shopping centers located at the "100% intersection" of the community, which had once been the crossroads for the area and the location of a more traditional town-like commercial district, has a number of interesting approaches for defining place and adding support for modes other than the car.

More on Biking as transportation.  Obviously, since the plan for Baltimore County was for biking and walking, it shouldn't be a surprise that earlier in the planning process, I came up with a framework for planning the bicycling (and walking) network in a more systematic fashion, at different scales:
  • within neighborhoods
  • one mile radius from schools and bus stops and transit stations
  • three mile radius from "town centers"
  • along corridors
  • between corridors
  • connections within and to parks, which I called a County bikeway network
  • connections to neighboring jurisdictions (Baltimore County has borders with Baltimore City, Anne Arundel County, Howard County, Carroll County and Harford County in Maryland, and York County in Pennsylvania.

I didn't think to include planning for the bicycle network as a separate point, instead it's incorporated into point #5. 

Relatedly, while it goes without saying that accommodations for cars are included within the road network, although most are provided by the private sector, for bicycling to be practical form of every day transportation, a network of biking infrastructure needs to be complemented with parking, repair stands, air pumps, mapping, etc.

A way to think about this for biking would be to extend the ideas of the Pennsylvania Trail Towns tourism promotion scheme to amenities, alongside a concept put forth in the German National Bicycle Plan, 2002-2012, that to treat "cycling as traffic," more than just the pathway space is required.
Bicycle Traffic as a system, diagram, German National Bicycle Plan, 2002-2012

Building on some of these ideas, later I suggested that metropolitan areas should create a  regional bike parking system, treating transit stations as a form of trailheads with bike mapping, air pumps, and repair stands, etc.

Salt Lake City has created a "Cycle The City" route as a kind of tourist route to see points of interest via bicycle.

The inclusion of these kinds of support facilities should be incorporated into the biking element of a "Signature Streets and Spaces" program.

More on Transit.  Similarly, a system for integrating improvements and enhancements to the transit network should be outlined in a more formal way.

More on Walking/Streetscape improvements.  The pandemic has sparked a focus on improving and expanding spaces for pedestrians.

In a recent piece, I suggested that regardless of the pandemic every city should have already been developing one pedestrian-exclusive spaces akin to Las Ramblas in Barcelona, Mare Street in Hackney, London, etc.

-- "Why doesn't every big city in North America have its own Las Ramblas?"
-- "Diversity Plaza, Queens, a pedestrian exclusive block"

More on Funding.  Another funding method is special service districts.  I've discussed that in terms of what I call Public Improvement Districts for transit station catchment areas ("Revisiting creating Public Improvement Districts in transit station catchment areas").

San Francisco has the Green Benefits District, which is funded by a surcharge on both residential and commercial properties, to improve and maintain public spaces.

More on Public Art.  There are many interesting ways and resources and examples for thinking about how to incorporate public art in the public space and as an element of the placemaking qualities of the mobility network.

For example, I've always thought that Cincinnati's Neon Sign Museum could create a signage public art program for the erection of arty signs throughout the city.

Two interesting projects I've come across lately are the Streetscape Improvements Playbook of the Memphis Medical District Collaborative and a city-wide project currently underway in Marseille.

Sponsored by MAMO, the city art museum for Marseille, the public artist known as Invader, who installs tile mosaics in public spaces across France, was commissioned to place 80+ works throughout the city ("French Street Artist Invader Secretly Installed His Art All Over Marseille This Summer—See It Here," Artnet).

As well as art works within transit stations and shelters or as elements of the stations, such as Centro Tower at a bus station in San Antonio by Bill FitzGibbon, incorporating light elements into bridges, etc.

More on Branding.  A group of graphic designers organized as The Neighborhood Project created logos for Salt Lake City's neighborhoods ("From the Avenues to Rose Park to Sugar House, designers give Salt Lake City neighborhoods their own logos," Salt Lake Tribune).

An identity system for Signature Streets needs to go beyond sign toppers for street signs.

Some places have gateway signage for places like neighborhoods and districts and commercial districts.

Branding and identity systems as part of program delivery in urban revitalization programs.  New New Hampshire Ave. , Takoma ParkThe City of Takoma Park came up with a logo as part of their New Hampshire Avenue revitalization program called "The New Ave."  It's an example of branding a Signature Streets program.

More on marketing.  Using events that promote sustainable mobility, e.g., the "Sunday Streets" program in New York City or the CicLAvia in Los Angeles is another way to market the Signature Streets network in an ongoing fashion.

This is necessary for the promotion of sustainable mobility as well as building ongoing commitment to maintaining, improving, and expanding the network, especially if funding needs to be re-approved every so often.

Transportation infrastructure as architecture.  More places are incorporating urban design and public art elements into transportation infrastructure, such as freeway abutments and overpasses, decorative plantings, etc.

Streets as linear parks.  Greening and plantings are an obvious addition to "roadsides", especially in commercial districts and town centers.  Because of the expense of maintenance, such urban design improvements may be left out of plans.  But this can be an important element of improving the aesthetic experience within the road (mobility) system.

The "parkway" approach from the 1910s-1930s is the obvious relevant design example that can be drawn upon for ideas.

Kearns, Utah ("Kearns upgrades are planted to help area grow out of 'the weed patch’: Improving street’s appearance is important to emerging community center," Salt Lake Tribune) has recognized this and has done attractive plantings on 5400 South, although their efforts are lost in the overall "aesthetic pollution" of the corridor as a whole. From the article:
Salt Lake County turned dirt on the "Gateway to Kearns," a four-block-long stretch of land on the south side of 5415 South that will be converted from a weed patch into a parkway including the county's first urban orchard with apples, peaches, pears and cherries. ...

"Kearns is maturing. Kearns is turning into a world-class community," said state Rep. Eric Hutchings, a resident. "To improve our look and feel around here means a lot."

He lauded Salt Lake County for "putting its money where its words are" in funding development of the parkway at a time when Kearns residents showed their appreciation for county leadership by voting to become a metro township.
Conflicts: the challenge in developing a Signature Streets network when streets cross jurisdictions..  A challenge for planning an integrated Signature Streets network is when there are multiple jurisdictions responsible for roads.  The concept is developed out of center cities that have significant control of the roadway and roadside characteristics of the mobility network within their cities.

Baltimore County doesn't have incorporated cities so the County is the primary actor.  In other counties, a mix of state, county, and local jurisdictions is responsible, with the local jurisdictions responsible for the roadside, the state department of transportation responsible for major arterials, and a mix of jurisdictions responsible for other streets.

5400 South in Salt Lake County is a perfect illustration.  Taylorsville wants to recreate its center at the intersection of South Redwood Road and 5400 South.  Kearns, on a section of the road, but only on the south side, has invested in plantings.  But overall the road functions like a big, wide highway, lined with a mix of industrial and commercial buildings most barely designed.

Corridor management as a solution.  In these situations, what is required is an overall multi-jurisdictional "corridor management" approach.  This could be a way for counties and state departments of transportation to provide guidance and leadership on the urban design and sustainable mobility elements of the "road network" that goes beyond today's more traditional and disconnected approach.

Conflicts: transit.  Another conflict between jurisdictions concerns transit operations, especially when transit agencies are run on a metropolitan scale.
