IRVINE, CA (February 10, 2005) - The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced financial results for
the fourth quarter and year ended December 31, 2004, which included record
annual net revenue and income from continuing operations.

FOURTH QUARTER AND YEAR END 2004 RESULTS

     Net revenue for the three months ended December 31, 2004 increased 6.6% to
$24.3 million, while income from continuing operations for the same period
increased 20.7% to $2.3 million and resulted in diluted earnings per share from
continuing operations of $0.28. This compares to net revenue for the fourth
quarter of 2003 of $22.8 million, with income from continuing operations of $1.9
million and diluted earnings per share from continuing operations of $0.24. Our
strong fourth quarter results were positively impacted by $210,000, net of
income taxes, related to a business development agreement in our
energy/industrial segment entered into in early 2004 and terminated at year end.

     Net revenue for the twelve months ended December 31, 2004 increased 6.6% to
a record $96.8 million, while income from continuing operations for the same
period increased 16.8% to a record $8.4 million and resulted in diluted earnings
per share from continuing operations of $1.05. This compares to net revenue for
the twelve months of 2003 of $90.7 million, with income from continuing
operations of $7.2 million and diluted earnings per share from continuing
operations of $0.91.

     Mainly due to stronger collections of accounts receivables, net cash from
operating activities for the year ended December 31, 2004 increased 113% to
$15.6 million, compared to $7.4 million during 2003.

     "Our real estate development segment continued to drive strong net revenue
gains in the fourth quarter," said Aram Keith, Chairman and CEO of The Keith
Companies. "This segment achieved 8.9% year-over-year net revenue growth for the
fourth quarter of 2004, and 14.9% net revenue growth for the year. We exited the
year with a strong pipeline of projects in our real estate development segment.
We believe that the real estate market will continue to grow in 2005. In
addition, we are encouraged by the continued improvement in the operating income
of our public works/infrastructure segment, and continue to pursue a variety of
opportunities in this area. Infrastructure concerns are one of the biggest
issues facing state, county and local governments and we believe that we are
well positioned to capitalize on infrastructure improvement projects that
receive funding. Year-over-year, our energy/industrial segment showed an
improvement in income from operations in the fourth quarter, and as we stated
previously, we expect this segment to continue to improve partially due to
legislation extending production tax credits for power generating projects that
use renewable energy sources. We continue to see improved proposal activity in
this segment."

     "Gross margins increased in all three of our business segments in 2004,
primarily as a result of improved employee utilization rate and higher fees.
This represents our second consecutive year of improved Company wide gross
margins, with this latest year improving by 190 basis points to 37.6%,"
continued Keith.

FINANCIAL POSITION

     The Company's balance sheet at December 31, 2004 remained strong with cash
and securities of $42.1 million, no debt, a current ratio of 4.8:1, and
shareholders' equity of $81.9 million, or $10.34 per common share outstanding at
December 31, 2004.

DISCONTINUED OPERATIONS

     During 2004, the Company made an investment in a private entity in the
energy sector and, in return, received a controlling interest in that entity. As
a result of the Company's controlling interest, the Company had consolidated the
entity's operating results with that of the Company. In December 2004, the
Company made a decision to shut down the operations of this entity primarily due
to lower than expected operating performance. In accordance with Generally
Accepted Accounting Principles, the Company has changed the presentation of its
"Consolidated Statements of Income" to reflect as discontinued operations the
results of this entity for 2004. The total loss, including the impairment charge
associated with this entity, net of income taxes, totaled $273,000 and $430,000
for the quarter and year ended December 31, 2004, respectively.

FINANCIAL GUIDANCE

     In adherence with the U.S. Securities and Exchange Commission's (SEC)
Regulation Fair Disclosure, The Keith Companies provides the following guidance
for all investors and encourages all current and potential investors to review
the disclosure regarding forward-looking statements in this press release as
well as all financial documents filed with the SEC. All

guidance amounts are before special items, if any, and exclude the impact of any
potential future acquisitions.

     The Company is increasing its financial guidance for diluted earnings per
share for 2005. The Company estimates its full year 2005 net revenue may range
from $106.5 million to $111.5 million with estimated diluted earnings per share
from continuing operations ranging from $1.09 to $1.25 ($0.21 to $0.24 for the
first quarter; $0.28 to $0.32 for the second quarter; $0.33 to $0.38 for the
third quarter; and $0.27 to $0.31 for the fourth quarter) based upon an
estimated 8.1 million weighted average number of diluted shares outstanding for
the year. The previous annual 2005 guidance for diluted earnings per share from
continuing operations ranged from $1.04 to $1.22. Consistent with the Company's
past accounting treatment of stock options, the 2005 diluted earnings per share
amounts exclude the effect of expensing stock options. New accounting
pronouncements, however, will require the expensing of stock options effective
for the first interim period beginning after June 15, 2005. The Company has not
completed its analysis as to the effect the new pronouncement may have on its
overall 2005 financial results.

     Commenting on the Company's financial guidance, Keith said, "Our revised
upward guidance for 2005 primarily reflects the on-going strength of our real
estate development segment, as well as expected improvement of our
energy/industrial segment and a lower estimated effective corporate income tax
rate of 38%. The recently opened San Diego and Bakersfield offices are fully
operational and we expect them to be contributors to the Company's performance
over the course of this year. Our robust financial position enables us to
explore various acquisition opportunities, in addition to new office openings,
that will deliver strong operational performance, as well as solid returns for
our shareholders."
