Urban Crossings - Los Angeles

Picking up on the threads of the Vegitecture post on 'Crossings', a post on The Dirt made mention of the plans to cap a number of freeways throughout Southern California. "According to The Architect’s Newspaper, there are four separate projects being considered across L.A.: one in Hollywood, one in downtown LA, and two in Santa Monica. “Hollywood Central Park would be built atop the 101 Freeway on a proposed 44-acre site between Santa Monica Boulevard and Bronson Avenue. Park 101 would be built atop the ‘Big Trench’ over the 101 Freeway downtown. Santa Monica is hoping to cap portions of the 10 Freeway between Ocean Avenue and 4th Street, and between 14th and 17th streets, creating five- and seven-acre parks.”

One project in this mix with some real traction is the Hollywood Freeway Central Park - which in 2008 developed a initial feasibility study with AECOM as the consultant. The report goes through a mix of analysis and exploration, along with a public involvement process. The idea of knitting the fabric of two severed neighborhoods with elevated park space drives the significant cost for capping projects - aiming to fix some of the damage done in the initial freeway routing.

A range of graphics include some typical analysis - as I'm always interested in seeing the old chestnuts like figure-ground analysis in urban design studies. I'm a fan of the figure ground as a tool, and this case in point reinforces the power of this tool to 'detach' from a system and make key connections.

In this case, most of these retain some of the key crossings... but take advantage of the ability to reorient circulation to create interesting spaces and maximize connectivity.

A range of precedent studies included notable capping projects like Millennium Park (Chicago), Big Dig Park (Boston), Olympic Sculpture Park (Seattle), and others showing examples of spanning roadways to connect disparate portions of the urban fabric.

Another graphic that seems to be in vogue (drawing from some of the scalar diagrams of the book Large Parks) - giving a sense of size and proportion to other established large urban park spaces.

The final concept creates somewhat of a linear park corridor, which is really a series of medium sized park periodically bisected with crossroads. The programs run the gamut from passive spaces to sports fields, sculpture gardens to plazas offering a range of uses - connected by pathways and crossings. There seems to be a range of possible options to use this new space that have been explored in many project proposals - from agriculture to mixed use infill - meaning a park is merely one option.

The simple photo-montage graphics show some dramatic before and after shots of the reclaimed space atop what was essentially a dead zone below.

Obviously time and economics will tell if this is a viable strategy to implement in our cities. The experience with the costly and issue-prone Big Dig has soured some on the idea, although the spaces that are emerging atop the depressed roadway is starting to pay dividends for a new public realm. Burying is one thing - spanning and capping is another, taking advantage of the existing configuration of roadway 'canyons' to reconnect spaces. My thought is that it is not the silver bullet, (more like a really expensive band-aid) but necessary (in lieu of freeway removal altogether) to strategically reconnect areas of the urban fabric that have been severed to a degree where health and livability are forever degraded. The expense means a surgical analysis is necessary to determine where to locate these for maximum impact, as well as how to program the spaces appropriately to make use of the space. There has been much renewed talk about this, so I imagine we will see more of these in the not-so-distant-future. And I think that's a good sign.

[Fill in the Blank] Urbanism

I attended a pow-wow recently - aimed at discussing the state of landscape urbanism theory and it's past, present, and future implications for planning, urban design and landscape architecture. Amongst many other interesting thoughts (more to come on this), one aspect of the conversation that stuck in my brain stuck was the recent (maybe?) upswing in the use of paired terms ending with the term 'urbanism' to describe a range of theoretical positions related to all things urban.



The general definition of urbanism fits a wide range of situations, making it an evocative word with easy addition of a modifier. Via Wikipedia: "Urbanism is a focus on cities and urban areas, their geography, economies, politics, social characteristics, as well as the effects on, and caused by, the built environment."

Packaged Vertical Garden

The 'Garden for a not too distant future' is an installation that is part vertical garden, part statement about the lack of green space in cities and the preponderance of overpriced, difficult to maintain vertical walls.

Via luzininterruptus: " With the installation Packaged vertical garden, we wanted to promote the preservation of urban greenery, because if we continue to eradicate it from public spaces or reducing it to inaccessible vertical faces, the only form of contact with nature will be in supermarket refrigerators, packaged with expiry dates. This is our last intervention “Packaged vertical garden”.
