The STROAD: 40th Street to Become a 'Super Stroad'


The '40th Street Multi Modal Project' Shows Emeryville Continues to Aspire to Be a Place to Travel Through On the Way to Somewhere Else

People Who Want to Travel to a Better Place Than Emeryville Will Be Helped by the $33 Million Infrastructure Project

"A stroad is a thoroughfare that combines the features of streets and roads.  Stroads attempt to be both a high speed traffic connector (a road) and a place for business and people (a street) but fails at both.  They are wide arterials (roads for through traffic) that also provide access to strip malls, drive-throughs, and other automobile-oriented businesses (as shopping streets do).  They are the most dangerous type of urbanized thoroughfare and have come under near universal criticism among city planning professionals.” WIKI

Emeryville has cleared the way to make traffic on 40th Street move more efficiently through a proposed $33 million infrastructure project known as the ‘40th Street Multi Modal Project, a project that will exacerbate current problems associated with a lack of habitability and the alienating civic space created by the street.  Effectively, Emeryville is preparing to turn a ‘stroad’ into a super-stroad and any improvements for bus travel or bike travel touted by proponents are threatened to be overtaken by a greatly diminished livable space for Emeryville by the pyrrhic effects of the 'improvements'.

The project, seven years in the planning and slated to begin construction in the new year, will cost $33 million, $5.5 million of that paid by the City of Emeryville and will likely result in higher speed traffic and more people moved per hour; part of the touted efficiency.  But in so doing, it will create a reduced access ‘super-block’ grid out of existing small blocks, cutting neighborhoods off from each other with more traffic noise and more air pollution for people living nearby.  The built out project promises to reduce desirability for neighborhoods close by, as these kinds of high efficiency arterials have been shown to do.  People who don’t live in Emeryville but who travel through or commute to our town or who travel here to go to the auto-centric shopping malls Emeryville has built will benefit however.

City officials insist the 40th Street project will not just help regional shoppers and people cutting through our town headed to other (more desirable) destinations, but it will also help people traveling to the planned $1 billion Sutter Health Hospital planned for Emeryville.

Proponents of the project which includes four out of five City Council members (Priforce dissenting), tell us bikes, bus users and drivers will be helped because of, rather than in spite of, the closing of 40th Street side streets.  The closing of the streets will create several 'super-blocks' of the sort that the late Canadian city planner Jane Jacobs warned us against.  She has shown how this consolidation of small blocks into super-blocks in the street grid devalues the neighborhood.   Discounting the Jacobs inspired city planning ethos (begun as a 1960's scrappy rebellion, now turned into orthodoxy), the proponents of the project have shown how traffic will move more efficiently, including bus traffic and bike traffic, with fewer (side street) conflicts.  Between Adeline Street and Halleck Street, there are currently nine small blocks that intersect 40th Street.  After the $33 million project is complete, that number will be reduced to six large super blocks.

Traffic engineers have long worked to increase flow rate efficiencies without concern for livability downgrades for people living nearby.  The real estate market has long shown how major arterials, including stroads and freeways, reduce value for home prices and there is nothing about the 40th Street Multi Modal Project that would suggest the improvement for traffic efficiencies it will bring will be any different.  Indeed, the market has shown people like their communities to be quiet as far as traffic goes, with the low speeds and volumes that low efficiency streets bring.

40th Street in Emeryville
Emeryville has three existing stroads: Powell Street, San Pablo Avenue and 40th Street.  These corridors exhibit all the negative effects of stroads: induced demand traffic congestion, high volume, high noise and pollution, danger, and other intangibles that equal a high ‘ick’ factor.  Improving the carrying efficiency of 40th Street, a street that already embodies these bad qualities, will only worsen the civic space.  It threatens to turn a stroad into a super-stroad.

Stroads are part of a rationally based modernist vision for cities.  Traffic engineers are taught the rationality of efficiency in graduate schools.  Towns that throw their transportation plans over to traffic engineers as Emeryville has done, tend to get less than desirable places.  Robert Moses, the formerly great urban planning expert knew about moving people with the greatest efficiency; he's the godfather of the top-down urban renewal ethos of the 1950s and '60s that bulldozed entire neighborhoods to build massive freeways cut through all across America.  His star however has been dimmed in recent years by people demanding more democratic control of their cities.  In this milieu, stroads seem to be a part of the last vestiges of this heavy handed vision of how not to create livable urban spaces.  The YIMBY movement too is part of the anti-democratic top-down Robert Moses vision but is not a vestige, rather it is a new iteration of the Moses vision.  YIMBYists' propose stroads to be used to connect their apartment towers to freeways for 'easy in, easy out' commuting to help developers maximize profits.    

The 40th Street Multi Modal Project calls into question what Emeryville is for.  Is it a place for people to come to, get stuff and leave?  Is it a place for people to travel through on their way to someplace else (more desirable)?  Is it a place where the politics have tried (and failed) to create a nice place to live or to be?  Stroads are built by municipalities that have no pride.  They are built by towns that pay deference to corporations seeking to make a profit.  After a couple of decades of Emeryville granting developers approvals to build auto centric sprawling shopping malls with big box retail surrounded by acres of parking lots, after another couple of decades building massive auto centric all-rental housing projects that are linked to the shopping malls and the freeway by stroads, after making Emeryville a place to get through in order to get to a place people desire to be, perhaps we should be turning stroads into streets as opposed to super-stroads.  

After spending $33 million on this project, it would seem Emeryville's future is already decided for the next 40 years, the useful life of this expensive infrastructure.  Desirability is out and moving people more efficiently by use of rational traffic management is in.  Regardless, people don't like being near stroads, living or lingering and Emeryville residents will be able to use the 40th Street Multi Modal Project for decades to come to travel from the place they live to places they want to be....places not run by developers and traffic engineers.
