It's so hot that the heat doesn't hang, it shimmers. And though Edgar Arceneaux tends toward the pragmatic, even he has to stop and question whether he's staring at a mirage.

Standing in the tilting, lacy shadow of Simon Rodia's venerable Watts Towers (once again wrapped in scaffolding for repair), Arceneaux looks on as a group of college students -- young men and women; white, black, Asian, Latin; some from USC, others UCLA, and still others from Cal Arts and Art Center -- have set to work in front of a modest, cream-colored stucco bungalow on 107th Street. This is the home of Felix and Maria Madrigal -- and brick-one of the Watts House Project.

A couple of dozen folks run in and out of the Madrigal's house, some in flip-flops and Bermuda shorts eagerly checking in on their assignment, some on their first trip to Watts. In all the commotion, Arceneaux, 36, a young artist on the rise, is difficult to miss. It isn't his height, 6-foot-2; it's his presence. He moves as languidly as his voice -- calm, unmodulated and seldom rising above a murmur.

He settles on the porch in a folding chair next to Susan Yank, head project coordinator, running down the lengthy to-do list before the official groundbreaking, set to happen in mere hours.

A few of the students pile into a car to pick up more clay tiles for the front walkway. Another group gets a primer on how to set up scaffolding. And a trio ofstudents begin to dig a deep trench for a new fence.

The plan is to rethink the Madrigal home based on their needs, their habits, their dreams. This means a new front walk, porch and light fixture -- all reimagined with an artist's eye. The most dramatic addition is to build out the porch, giving the Madrigals more space. A model for things to come.

It's been a long time coming -- a decade in the making -- which contributes to a measure of Arceneaux's disbelief. Especially in a place like Los Angeles, which often puts more credence in the region's myths than the realities.

What Arceneaux has been up against is more pernicious: It's those other sorts of myths, misconceptions -- about race, about class, "about us and them, black and brown divided" -- that have had him both working double-time and kept him on course.

What is Watts? What does Watts need? And what does Watts deserve? These have been among the hard questions Arceneaux, with the help of residents, hopes to answer. To the outside world, Watts is many things: code, a euphemism, a one-word cautionary tale. "It's a place that everybody thinks they know about but are afraid to go to," says Arceneaux. "And this project offers a chance for people to come together and build something collectively."

Off the ground

After dozens of community meetings, fundraisers, late-night porch talks and a trip to buy a foreclosed property at auction, this first chapter of Arceneaux's venture -- a grand-scale collaboration involving local artists and the city's major arts and educational institutions, as well as residents -- is finally beyond the drawing board phase. Based on artist Rick Lowe's Houston development, Project Row Houses, the Watts House Project (WHP) -- part conceptual art, part activism -- is a mission that Arceneaux, its director, describes as "an artwork in the shape of a neighborhood development."

At the moment, his medium looks like many old streets in L.A., those elder neighborhoods that have eluded the nip-and-tuck of assembly-line gentrification. Here stands a row of bungalows, some stucco, others with their original wood, some fronted by neat lawns, or gardens tangled with succulents or bright splashes of bottle brush. Down the street, on this September afternoon, two neighbors watch under the harsh sun; another, down the block, is trimming a tree as carefully sculpted as a bonsai. Some windows concealed by bars are the only hints of anything untoward.

Much of the project is about just this: the nuances. It's what gets lost in the overview: the day-in, day-out stories of a section of L.A. that has seldom had a chance to define itself for itself -- let alone to the world. To this end, Arceneaux wants to fold together the history of the neighborhood alongside the stories of its residents, pairing artists with architects, creativity with practicality. He hopes to get to all 20 structures on 107th Street -- refurbishing four a year for the next five years -- and expand to create exhibition spaces, cafes, gardens and artists residences. "Instead of using clay, we're using time and space to sculpt a neighborhood and relationships."

While it isn't lost on Arceneaux that his project sits in the shadow of one of the more famous monuments to the quixotic, his ground-up approach is what has attracted vital support from L.A.'s arts community. LAXART, a Culver City-based nonprofit contemporary art exhibition space, has taken WHP under its wing. The project has received funding from the nonprofit Creative Capital and UCLA's Hammer Museum, and support from USC's School of Architecture, the Watts Towers Arts Center and the interdisciplinary producer ForYourArt. "It's crucial to explore ways for artists to work outside the gallery walls," says ForYourArt founder Bettina Korek, "and in this case, enhance community resources." Of the estimated $1 million they need for the work on 107th Street, they've brought in $85,000.

Easing concerns

For all the good intentions, Arceneaux has come against roadblocks and suspicions. Homeowners worry if it's another city plan to lop off a piece of their backyard for a parking lot. Some community leaders balk, apprehensive that it might be some hidden agenda wrapped in altruism: "A lot of it," says Arceneaux, "has been convincing the surrounding Watts community that the intentions are noble and progressive . . ."

"[People] go to meetings and listen to promises," says Felix and Maria's son, Oscar Madrigal, 30, who still lives nearby. "But 'Nothing ever comes through.' 'When will we see tangible results?' So he hasn't had it easy."

Paired with this is a general skepticism of outsiders -- much of it a reaction to how the outside looks in, says Municipal Art Gallery director Mark Greenfield, who worked as director at the Watts Towers Art Center: "I'd get these calls from a university. And it would be some sort of anthropological thing where they would treat people in Watts like laboratory animals -- 'How many kids did drugs?' 'How many kids in gangs?' So I think a lot of distrust began to develop."

So if the "medium" is the built environment, Arceneaux's essential tools are these volunteers, designers, residents and people who can be described only as neighborhood griots who have witnessed Watts' changes -- people like Felix Madrigal, who has lived in the neighborhood for more than 20 years, or artist John Outerbridge, who served as the director of the art center for more than 30. What Outerbridge finds most noteworthy is that this endeavor honors both the history of the people and that of these hand-crafted houses. "Up until now, the story of gentrification and architectural philosophy [in Watts] didn't include this." Arceneaux's project broadens the concept of both art and its process. "It demonstrates that art has the audacity to be anything that it needs to be."
