The San Francisco Stormwater Design Guidelines (Guidelines) describe the requirements for stormwater management in San Francisco and give developers the tools to achieve compliance. The Guidelines were adopted by the San Francisco Public Utilities Commission on January 12, 2010.

Bicyclists have begun taking advantage of the new bike lanes being installed this week along the western section of the 17th Street corridor, with many riders saying they began feeling a greater sense of safety just as soon as the first stripes were laid down by Wednesday from Valencia to Church Streets.

In interviews with Streetsblog, several people on bikes roundly cheered the improvements, described as simply “fantastic” by one rider. “It’s really nice because we always bike on 17th Street and the [car] traffic is not that high,” said another traveler trying out the new lanes with a partner.

“Improvements on 17th Street will help the fast-growing number of people bicycling between the Castro, Mission and Potrero neighborhoods,” said San Francisco Bicycle Coalition executive director Leah Shahum. “There are so many families with children riding bicycles in these areas already, and this new bike lane will help welcome even more people of all ages onto their bicycles.”

SFMTA counts show a 75 percent increase in bike traffic on 17th Street at Valencia from 2006-2010, according to Shahum. The long-awaited project comes as part of the San Francisco Bike Plan, which is currently being put into action after a four-year bike injunction delay.

While SFMTA crews have begun work along the roughly two-mile stretch from Corbett Avenue to Kansas Street, bike lanes between Church and Sanchez are temporarily on hold as planners try to figure out a solution that addresses safety concerns about the streetcar tracks, according to the SFMTA Sustainable Streets Division’s Mike Sallaberry.

Just in the nick of time, the House has passed an extension of the current transportation law. The sixth extension of SAFETEA-LU was set to expire this Friday.

The extension is not expected to face any problems in the Senate.

Although the House has been cutting every expenditure it can get its hands on, it can’t get its hands on the bulk of the surface transportation program, since it’s funded out of the dedicated Highway Trust Fund (in the process of being renamed the Transportation Trust Fund). This extension passed the House 421-4.

The storage, preparation, and consumption of food all contribute to the generation of food waste. A new WERF study will examine the economic, environmental, social and operational considerations of food waste management as part of domestic wastewater treatment operations. This project is part of ongoing WERF research into co-digestion under OWSO5R07, Co-digestion of Organic Wastes with Wastewater Solids. The food waste study is scheduled for completion in spring 2011.

Food waste is a significant part of domestic wastewater, from residential food preparation, including disposers used by homeowners, restaurant discharges into sewers, and co-digestion, which is primarily focused on institutional and commercial food waste trucked directly to digesters. Food waste comingled in domestic sewerage operations augments organic matter with sewage sludge which may improve digestion and boost methane production.

A CDM research team will examine food waste transport to the wastewater treatment plant via direct injection of trucked-in food waste and food waste transported to the treatment plant in sewers after being introduced through a kitchen grinder. For comparison, food waste disposed in landfills or part of green compost will be assessed for its carbon footprint and environmental impact.

Researchers will also evaluate the behavior of food waste through a generically configured treatment plant that uses raw water screening and grit removal, primary clarification, activated sludge treatment for carbonaceous BOD removal, hypochlorite disinfection of treated effluent, solids thickening, anaerobic digestion with cogeneration, biosolids dewatering, and biosolids land application. The assessment will provide a consistent basis to identify which food waste management practice is “greener” and what factors affect the best practice over the life cycle of each management alternative.

The sum of dollars received per year from all advertising ranges from $22 to $25 million (including BART-operated advertising in Muni Metro stations), a large enough amount to be an integral part of the Metropolitan Transportation Agency’s revenues, according to Ms. Bose, CFO of SF Municipal Transportation Agency.

However, targeting income from contracts with Titan and Clear Channel as a measure to clean up the proliferation of advertising is the wrong approach according to Ms. Bose. She stated the main problem with funding MUNI is the lack of a direct source of guaranteed funds – no tax, fee or other revenue-generating options are earmarked exclusively for the Agency. Furthermore, no singular policy board governs all facets of the system. The San Francisco County Transportation Authority (TA) is responsible for capital improvements, and the MTA is responsible for operating the transportation services. As a result, the TA may fund transit improvements and the MTA may have to scramble to find the funds – starving other service areas – to run the improved system.
Ms. Bose also discussed in detail several options to free up funds at the MTA. Long viewed as a problem on MUNI, fare evasion results in a yearly loss $22 to $25 million, equal to that of advertising revenues.

B. Bailey from Ottawa, Ontario, Canada, asks “If the political will were there, is it even possible to build enough wind, solar, hydro, geothermal, advanced vehicles, etc, to get the entire world to carbon zero by 2050?” and is answered by Steve Clemmer, Director of Energy Research…

Robert Noble, the CEO of Envision Solar, has said that solar installation has (or will) become the domain of builders and electrical contractors, since these companies are already on the rooftop with extensive building experience.  He claims that solar installation is now “about the building industry.”

One of Envision’s differentiators, according to Noble, is that “we are architects and planners” who know how to “design, engineer and build.”  The San Diego, California-based company began trading on the OTC bulletin boards via a reverse merger a few months ago.

Envision is already in the business of building solar carports.  In Noble’s thinking, carports were “the largest single market for distributed solar power generation. [. . .] It’s better than drilling into a waterproofed roof,” according to the CEO.

Clean coal technology is on the drawing board. It’s a part of the great hope. Since coal is our currently ourbiggest source of energy, we must consider ways to clean it, however, we are not there yet. New systems are being considered and perhaps some of them may some day work, but in order to be clear, we must realize that this technology does not yet exist. More later on this subject. Anyone with an opinion or more detailed knowledge is invited to comment further.

(Excerpt from Alternet) By Antrim Caskey
“The Coal Spill Disaster in Kingston – has clued Americans in to the real consequences of coal. We use coal-fired power for almost half of our daily electricity use; when you turn on your lights, your plasma TV or laptop computer, you are probably using coal. The coal industry, which has come under sustained attack, especially in the wake of global climate change, is spending tens of millions of dollars on a public relations war to convince Americans that coal is good and clean.”
