          THE KEITH COMPANIES REPORTS YEAR END RESULTS WITH YEAR OVER
                      YEAR INCREASES IN THE FOURTH QUARTER

IRVINE, CA (February 12, 2004)... 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, 2003.

     Net revenue for the three months ended December 31, 2003 increased 1.9% to
$22.8 million, while income from continuing operations for the same period
increased to $1.9 million and resulted in diluted earnings per share from
continuing operations of $0.24. This compares to net revenue for the fourth
quarter of 2002 of $22.3 million with income from continuing operations of $1.8
million and diluted earnings per share from continuing operations of $0.23.

     "We are very pleased with our year over year growth for the fourth quarter,
which was driven by increasing demand for our residential real estate services
in both Northern and Southern California," said Aram Keith, Chairman and CEO of
The Keith Companies. "In the fourth quarter, our real estate services generated
organic net revenue growth of approximately 10.6%. The net revenue growth in
this area was offset by continued weakness in the energy/industrial segment,
although we continue to be encouraged by the increased level of interest for
significant projects in this area in the future."

     Net revenue for the twelve months ended December 31, 2003 decreased 0.9% to
$90.7 million, from $91.6 million for the twelve months ended December 31, 2002.
Income from continuing operations for the twelve months ended December 31, 2003
decreased to $7.2 million, and resulted in diluted earnings per share from
continuing operations of $0.91 compared to $8.4 million or diluted earnings per
share from continuing operations of $1.07 for the twelve months ended December
31, 2002. Two notable items impacted the previous year's results. Interest
expense and other income during 2002 was positively impacted by $498,000 (net of
income taxes) of purchase price adjustments associated with the Company's
acquisitions of Crosby, Mead, Benton & Associates and Hook & Associates
Engineering, Inc. Other income in the fourth quarter of 2003 was positively
impacted by a $45,000 (net of income taxes) purchase price adjustment associated
with the Company's acquisition of ALNM Group, Inc.

FINANCIAL POSITION
     The Company's December 31, 2003 balance sheet remains strong with cash and
securities of $28.9 million, a current ratio of 4.7:1, a debt to equity ratio of
0.00:1 (excluding

issuable common stock) and shareholders' equity of $72.0 million or $9.40 per
common share outstanding at December 31, 2003.

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's financial guidance for 2004 remains unchanged from the
guidance previously provided. The Company estimates its full year 2004 net
revenue may range from $90.0 million to $100.0 million with estimated diluted
earnings per share ranging from $0.88 to $1.04 ($0.19 to $0.22 for the first
quarter; $0.22 to $0.26 for the second quarter; $0.26 to $0.31 for the third
quarter; and $0.21 to $0.25 for the fourth quarter) based upon an estimated 8.1
million weighted average number of diluted shares outstanding for the year. The
higher range of the guidance is primarily based upon significant improvements in
the demand for services in the Company's energy/industrial segment.

     "Our position as one of the leading residential real estate engineering
firms in California provides excellent opportunities in a rapidly growing
market," said Keith. "Overall, the beginning of an economic recovery,
infrastructure deficiencies, overdue capital spending and legislative
enticements, lead us to believe that the energy and industrial markets will
begin to experience growth in the not too distant future. In addition to our
planned organic growth, we are encouraged by the prospects for generating
incremental growth through the acquisition of complementary firms that can
expand our service offerings or enable us to achieve better penetration in
attractive markets. We are in various stages of performing due diligence on a
number of acquisition candidates. Following our due diligence review, if we
believe that the acquisition of any of these candidates would enhance
shareholder value, we intend to negotiate definitive purchase agreements to
acquire those candidates to drive additional growth in future years."

     The Company will be hosting an earnings conference call, which will be
