OWNER, COMET SKATEBOARDS
A typical skateboard deck is a sandwich of unsustainability: chemical epoxies pressed between layers of overlogged maple and coated with toxic varnishes. In 1998, Salfi cofounded Comet Skateboards (cometskateboards.com) with the goal of creating a greener board. At its solar-powered San Francisco factory, the company makes decks with Forest Stewardship Councilcertified wood, then builds the boards in Oakland with water-based glues and coatings. This fall, Salfi, 36, plans to launch a biodegradable board made of plant-based composite material.

SENIOR DEVELOPMENT ENGINEER, TESLA MOTORS
Can Silicon Valleybased Tesla Motors (teslamotors.com) give the electric car a much-needed jump start? Mendez, 38, who joined Tesla in 2005, says yes, citing key numbers for the company's Roadster (MSRP: $98,000), which goes into production this fall, as proof: 100 percent electric, zero to 60 in four seconds, 200-mile-plus range per charge. Think Porsche crossed with Prius. Further evidence: The technology used in the lithium-ion battery pack Mendez helped design is now being sold to other forward-thinkers, including Norwegian car company Think, which signed a $43 million deal.
OWNER, FARMER BROWN RESTAURANT
The menu at San Francisco's Farmer Brown (farmerbrownsf.com) features a "picture" of African-American farmers steering mule-drawn plows toward San Fran's iconic skyscrapers. The faux image deftly captures what Foster is after: delivering authentic soul fooddelicious and healthy, made with local, organic ingredientsto the Bay Area. The 33-year-old North Carolina native cooks recipes handed down from his grandmother, focusing on the kind of fare he couldn't find when he moved to the Bay Area in 1996. He also sees his cuisine as a way to preserve African-American culinary traditions. "Kids these days are not into cooking, and not into sustaining their culture," he says. "That's a crying shame."

FOUNDER, RCP TIBURON MILE
Competitive swimmer Placak decided on his 40th birthday to give something back to his sport. The gift? A one-mile open-water race from San Francisco Bay's Angel Island to the dock in his hometown of Tiburon. Since its debut in 1999, the RCP Tiburon Mile (rcptiburonmile.com) has become one of the world's premier open-water swims, drawing Olympians like Amanda Beard and Brooke Bennett. Some 800 racers are expected at this year's event, September 16. Placak, 48, also uses the race to raise funds for the Special Olympics; to date, his efforts have brought the national organization more than half a million dollars.

EXECUTIVE DIRECTOR, GREENBELT ALLIANCE
In the next 12 years, 1.5 million newcomers are expected to move to the San Francisco Bay Area. Sprawl threatens to gobble up a tenth of the region's remaining green spaces. Steinbach, 42, and his team at Greenbelt Alliance (greenbelt.org), a nearly 50-year-old Bay Areabased conservation group, are armed and ready. He recently helped persuade San Jose to keep the South Bay's Coyote Valley from becoming an industrial campus. His tactic: pressing outlying suburbs to direct their development inward, focusing their growth around existing downtowns and public-transportation hubs. "We see protection of open space and the creation of more livable, walkable cities as two sides of the same coin," says Steinbach. "The more you do of one, the more you get of the other."

EXECUTIVE DIRECTOR, BIG CITY MOUNTAINEERS
You've heard of camping programs for at-risk teens. But Big City Mountaineers (bigcitymountaineers.org) goes one better than the typical weekend trip, pairing urban kids with adult mentors (five of each) and sending them off on eight-day backcountry stints. East Bay resident Godley, 38, volunteered as a trip leader himself before joining the nonprofit in 2003. Since then, he's increased the number of participants served by the program by 30 percent each year, transforming hundreds of kids' lives. "I've had mothers come up to me," he says. "They say they can't put their finger on what's different, but they tell me something about their child has changed."
