Map of the Month

December 2006

This map depicts the locations worldwide where the various components that will be used to construct the Self-Anchored Suspension (SAS) Span are being fabricated. They will slowly begin to appear on-site later in 2007, with individual bridge deck sections coming into place beginning in 2009. Simultaneously, a considerable amount of work will be occurring on the Yerba Buena Island tunnel interface, as well as at the Oakland touchdown. When complete, the SAS will be the longest single tower, self-anchored suspension bridge in the world, and is expected to be fully open to traffic in 2013.

October 2006

This month's map depicts average Bay Area local road pavement quality, a subject which received considerable press attention last week following a press conference that featured Commissioners Beall and McLemore releasing the latest MTC pavement condition report. As you can see, average pavement conditions are poorer in the North Bay, which in part probably reflects the lack of a dedicated local transportation sales tax in two of our four northern counties.

September 2006

This month's map illustrates the change in total resident workers between 2000 and 2005 according to the U.S. Census Bureau. The Bay Area lost over 121 thousand resident commuters between 2000 and 2005, a 3.7 percent decrease. The Richmond District in San Francisco lost over 13 thousand resident workers between 2000 and 2005, from 76,400 to 63,030 -- a 17.5% drop. This was the highest drop of resident workers in the region. East Contra Costa County (Brentwood/Byron) had the highest increase in resident workers, gaining over 9,600 resident workers between 2000 and 2005. This area grew from 49,890 in 2000 to 59,560 in 2005 — a 19.4% increase.

July 2006

This month's map depicts collisions involving bicycles or pedestrians, and any resulting fatalities, from 1997 through 2004. The source data was reported by the CHP State-Wide Integrated Traffic Records System for every city in the nine-county Bay Area, including totals for the unincorporated portion of each county. From 1997 through 2004, there were 46,819 total collisions involving bicycles or pedestrians in the Bay Area. Of these, there were 1,076 fatalities, including 166 bicyclists. This is an average of 154 total fatalities a year, including 24 bicyclists.

June 2006

This month's map illustrates public transit service coverage in the Bay Area based upon the number of bus, rail, and ferry stops within one-half mile. As you might expect, the greatest density of service is clustered in downtown San Francisco where there are more than 180 transit stops within one-half mile of the central business district.

May 2006

This month's map represents a bit of a departure, since it is not specific to the Bay Area. I thought the commission might be interested, however, in a map I discovered on the Internet that depicts current gasoline pump prices by county throughout the United States. As you are already painfully aware, California has the highest gas prices in the nation. If you don't mind driving a fair distance to fill up your tank, the lowest prices appear to be in Wyoming.

April 2006

The map of the month depicts median household income in our nine-county region. The map shows both low and high-income communities spread throughout the Bay Area — although many low-income neighborhoods are concentrated in the inner East Bay.

March 2006

This month's map is a re-do of the last month's depiction of the most congested freeway locations in 2004. As noted by Commissioner Haggerty, last month's map contained a few inaccuracies that have been corrected.

February 2006

We are all used to the annual ritual of releasing the "top ten" most congested freeway segments in the Bay Area. The Map of the Month goes beyond the "top ten" list to depict all of the major congested freeway segments in the region by degree of severity. As you can plainly see, the I-80 approach to the Bay Bridge is in a class by itself.

January 2006

This month's featured map (see Attachment 6) depicts the commuter rail right-of-way (ROW) network in the Bay Area and shows ROW owned by public agencies as well as leased from private railroads for public use. The map also shows privately owned ROW that may shortly be purchased by public agencies to run the proposed eBART service in Contra Costa County and the restored Dumbarton rail service in the South Bay.
