Urbanization is affecting the abundance and balance of the Earth’s fragile ecosystems. The 21 companies on the 2012 San Diego Business Journal’s Environmental Consultants list provide services to balance necessary and inevitable progress with preserving the environment.

Dudek, ranked No. 1 on the list with 181 local environmental employees, is an Encinitas-based environmental and engineering services firm.

The criterion used for ranking the list is the number of San Diego County environmental employees as of Jan. 1.

“We have had an environmental practice for the last 22 years and it’s a predominant part of our business.” said Mark Forster, marketing director. “Dudek is strictly focused on California; it’s a complex place to do business.”

Frank Dudek founded the company in 1980 to provide civil engineering services to water and wastewater agencies, Forster said. In response to a growing need for environmental services in the 1990s, the founder launched an environmental practice with June Collins, who is now Dudek’s executive vice president and environmental practice manager of one of the largest such practices in California, Forster added.

“California is a giant Sudoku puzzle in terms of how projects receive regulatory approval,” Forster said. “Everything —  from wetlands and habitat, to groundwater and surface water to air quality — is interrelated in terms of the rules, and it would be difficult for any one person to get through this puzzle on their own.”

Persistence Pays Off

Dudek’s projects include working with the City of San Marcos for 14 years to get the permits necessary for the planned mixed-use, 214-acre downtown area along the San Marcos Creek District, which includes a native habitat preserve and multiple infrastructure improvements. Dudek’s environmental permitting specialists interfaced with the regulatory agencies involved. “The permits were recently granted to the city,” Forster said.

Another high-profile project for Dudek is managing the development of a Natural Community Conservation Plan for a six-county region in the Mojave and Colorado desert areas, headed up by Collins. The NCCP is a required process that establishes how biological resources can be protected while allowing compatible economic development.

The project is part of the Desert Renewable Energy Conservation Plan, which is part of a 2009 executive order by the State of California that establishes a policy of obtaining a new 33 percent renewable energy portfolio standard for the state, according to a company statement.

Rising Revenues

Santa Ana-based Chambers Group Inc., No. 8 on the list with 62 local environmental employees, reported 372 percent growth in gross local environmental revenue from 2010 to 2011. The company went from $3.3 million in 2010 to $15.6 million in 2011.
