Caltrans Employees Offer Others a Helping Hand

Stewardship is a broad category that covers a wide range of issues such as aiding small businesses, exporting emergency technology to nations coping with disaster; and preserving the natural world.

echo summit gets a face lift

This year, for example, Caltrans continued its commitment to aiding small and disadvantaged businesses to obtain state contracts. And in March, a federal court ruled that the Department was on the right track.

A U.S. District Court affirmed that the Caltrans Disadvantaged Business Enterprises (DBE) program is “clearly constitutional.” The Department implements the DBE program as a condition of receiving $3 billion in federal transportation funding annually. The program is intended to level the playing field for disadvantaged and small businesses competing for public contracts.

In 2005, the Ninth Circuit Court of Appeals provided new guidance to states on implementing DBE programs (Western States Paving vs. Washington State Department of Transportation). In response, Caltrans conducted a study to identify the existence and scope of discrimination, if any, in California’s highway transportation contracting industry.

Completed in 2007, the study identified disparities in contracts awarded to African-American, Asian Pacific-American, and Native American firms, as well as businesses owned by women. To address those disparities, Caltrans proposed using both race-neutral and race-conscious means in its contracting. In 2009, the Federal Highway Administration (FHWA) approved the proposal, which includes an overall goal of 13.5 percent DBE involvement.

The ruling followed a suit filed in 2009 by the Pacific Legal Foundation (on behalf of the Associated General Contractors of San Diego) asking the court to declare Caltrans’ DBE program unconstitutional.

While the suit was pending, Caltrans continued its outreach to Small Business (SB), Disabled Veteran Business Enterprise (DVBE) and DBEs. This effort — consisting of more than 80 events with nearly 8,000 attendees — focused on procurement and contracting opportunities with the state, workshops, and business networking.

The Department held events throughout the state to facilitate networking and subcontracting opportunities to SB, DVBE and DBE firms. Through a contract with the Los Rios Community College District, Caltrans provided supportive services to DBE companies. The services consisted of free, one-on-one counseling; online training; technical assistance; and marketing and outreach services to firms seeking transportation-related construction contracts.

As a result of such efforts, Caltrans met and exceeded the SB participation goal of 25 percent and DVBE goal of 3 percent in fiscal years 2008-09 and 2009-10. In FY 2009-10, Caltrans contracted nearly $400 million with SBs and DVBEs.

In a related development, Caltrans was named by the readers of Diversity/Careers in Engineering & Information Technology magazine as among the nation’s top performing companies to institute key elements of diversity in the workplace. This is the second year in a row Caltrans was granted the honor.

To date, approximately 50 state buildings have achieved LEED certification. For a complete list of LEED certified state facilities, read more.

In yet another example of stewardship, technology developed by Caltrans and the United States Geological Survey (USGS) helped set priorities for bridge inspections during the earthquake crisis last March in Japan, as well as in nuclear power plants around the world.

The ShakeCast software application uses ground sensors of analyze earthquake-shaking data in relation to the performance characteristics bridges or other structures. This allows responders to set priorities for inspections within minutes of an earthquake.

The International Atomic Energy Agency (IAEA) used ShakeCast to monitor the potential for damage to nuclear facilities in Japan following this spring’s earthquake. The IAEA also uses ShakeCast to monitor 196 nuclear power plants around the world.

Following a tremor, one of Caltrans’ most critical tasks is to assess the condition of bridges and roadways. In the past, inspection teams had difficulty setting priorities because they lacked precise information about where the worst shaking and greatest damage had occurred.

Caltrans recently executed a new three-year contract with the USGS to continue the development of ShakeCast. The new version will incorporate improved bridge models and will include an assessment of soil liquefaction and landslide hazards to post-earthquake roadways.

On the environmental front, Caltrans began work this year on a restoration of the Otis R. Johnson Wilderness Park, a seven-acre oasis in Fort Bragg that offers shady walking trails through native plant species.

The project included streambed restoration of habitat and stabilization of mature redwoods, replaced a footbridge, and installed boulders and wood debris to protect the stream bank. It removed invasive plants and restored native species. Completion is scheduled for next year.

The project added lanes that would have encroached on the wetland. As a mitigation effort, Caltrans built a wall to protect the wetland, and saved enough space for a bike/pedestrian path. The wetland is open to the public for enjoyment and education.

In the Los Angeles area, Caltrans District 7 helped to preserve infrastructure by removing debris and litter from its right-of-way at a cost of $13 million. Caltrans swept 31,875 lane miles, picking up 11,500 cubic yards of debris, disposing of almost 17,000 cubic yards of litter, removing 256 homeless camps, and cleaning up 267 spills. In addition, Caltrans covered 2,980 square feet of graffiti in the area at a cost of nearly $2 million.

In the “it-could-only-happen-in-California” category, Caltrans District 10 based in Stockton gave a hand to the San Joaquin Valley’s grape harvest.

Major maintenance has been required over the years to preserve this important two-lane interregional route.

The work could not be done safely at night, making a daylight closure necessary. So, last August the stretch of highway was closed for three days from 7 a.m. to 4 p.m. to allow for maintenance activities — saving both time and money.

photo of Rio Vista bridgeAfter reaching out to the San Joaquin Valley Farm Bureau, Caltrans set a date and time for the three-day closure — which ensured the work would not disrupt the area’s grape harvest and delivery to Napa Valley processors. The closure allowed crews to perform multiple maintenance activities on the highway both efficiently and safely. And the innovative plan prevented 15 days of one-way traffic control, which had been expected to cause 90-minute delays or more.

In another example of stewardship, Caltrans restored some 15 acres of vernal pool wetlands for future mitigation needs on 198 acres along SR-41 in Madera County. The construction not only provided dollars to a locally owned small business, but was the achievement of years of negotiations with resource agencies.

The Caltrans team forged partnerships with resource agencies to craft a development plan with a minimum of hurdles, while addressing future mitigation needs and preserving habitat for sensitive vernal pool species. As a result, Caltrans received recognition from the U.S. Fish and Wildlife Service. Besides improving relations with resource agencies, the mitigation project is expected to become a model for streamlining project delivery for years to come.

Caltrans also got a “thumbs up” for its work on two mitigation sites near San Diego. The Del Mar Auxiliary Lane Mitigation Project, begun in 2005, not only followed state and federal environmental law, but was a plus for birds, wetlands and those who enjoy the natural world.

Located on I-5 near the San Dieguito River, this project stabilized eroded slopes that could potentially affect wetland habitat. Three locations totaling a quarter of an acre needed repairs to failed culverts that allowed sediment to fill the wetlands. Caltrans excavated the area and replanted it with appropriate vegetation. The salt marsh, now restored, provides nesting and foraging habitat for black-necked stilts, song sparrows, and other bird species.

Another San Diego-area mitigation project is next to the Carmel Valley Restoration and Enhancement Project at the I-5/SR-56 interchange. This project, which was started in 2002, mitigated construction effects on about half an acre of wetland, which in turn required creation of an acre of new wetland habitat at the site.

Due to the high salt content of the soil, vegetation cover was lower than anticipated. The U.S. Army Corps of Engineers requested additional plantings. When completed, the site received sign-off from the California Department of Fish and Game, California Coastal Commission, and the U.S. Army Corps of Engineers.

Meanwhile, on the arid edge of the Inland Empire, Caltrans began erecting a new Colorado River Bridge on SR-62 in a remote area of San Bernardino County. The Department also forged links with the state of Arizona and the Colorado River Indian Tribes (CRIT) Reservation.

The bridge, which was narrow, heavily scoured and obsolete, was a vital link between California and Arizona. One of only a few Colorado River crossings, the span enabled a large influx of local, commercial and recreational travelers during spring and summer, causing traffic delays.

In cooperation with the Arizona Department of Transportation, Caltrans began work to replace the 76-year-old bridge with a $26 million modern structure, which will move commercial and recreational traffic more readily. Work is expected to take 2 ½ years.

Caltrans worked diligently to respect the rights and the wishes of the CRIT residents as well as meeting current construction standards. Given the remote location of the project, a number of cooperative agreements were put into effect, outlining law enforcement, fire and emergency medical services.

Caltrans is the construction lead agency on the project. Arizona and California each contributed $13 million towards the project.

Caltrans also published its “Complete Intersections: A Guide to Reconstructing Intersections and Interchanges for Bicyclists and Pedestrians” this past year. The publication gives direction on implementing the Caltrans Complete Streets policy. The guide is intended to improve safety and mobility for bicyclists and pedestrians at intersections and interchanges.

Caltrans Gives an Energetic Thumbs up for Solar Power

Caltrans is using Clean Renewable Energy Bonds (CREB) to fund environmentally friendly solar projects on its own facilities. The CREB program, authorized in the federal Tax Incentives Act of 2005, is intended to encourage energy conservation, and to increase the use of alternative energy sources. The CREB program is administered by the Internal Revenue Service.

The Department became aware of the program mere weeks before the application’s due date. However, Department staff used satellite imagery and as-built plans to identify candidate sites for photovoltaic (PV) systems, and submitted 94 CREB applications of which 93 were approved.

The Department then began collecting additional data for each site assuming the PV installations would be on the roofs of existing Department buildings. This included the age of the roof at the time of planned installation, structural soundness, long-term retention of the complex, and analysis of the utility energy data.

The result was a legislative package approving 70 sites totaling $19.9 million. Sites included maintenance stations, equipment shops, transportation management centers, materials labs, truck inspection facilities, toll plaza buildings, office buildings, and safety roadside rest areas.

CREB funding was a first for the state, and Caltrans was the only state agency in California to apply for the program. A funding process needed to be developed to use the CREB bond funds for construction of the PV systems. In cooperation with the State Treasurer's Office, the Department of Finance, and the Legislature, a successful process was developed. The IRS required CREB bonds be sold by June 2009, and all construction completed by November 2011. The Department has completed its goal.

Caltrans developed expedited project schedules and delivery plans. The Department sought to encourage participation by Small Business and Disadvantaged Business Enterprises, and Caltrans held a contractor outreach session to attract a maximum number of projects under $250,000.

To date, of the 70 scheduled sites, 54 have reached completion and are generating power. The current projected energy production is for 2.4 megawatts of solar power. The panels have a life expectancy of 25 years or more. They will be an important factor in Caltrans meeting its energy conservation goals as set in Governor's Executive Order S-20-04, and to support state renewable power, electric grid demands, energy conservation, and climate change mandates.
