              THE KEITH COMPANIES REPORTS THIRD QUARTER RESULTS AND
             CONTINUED STRENGTH IN RESIDENTIAL REAL ESTATE SERVICES

IRVINE, CA (November 6, 2003)... The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced financial results for
the third quarter ended September 30, 2003.

     Net revenue for the three months ended September 30, 2003 decreased 7.9% to
$22.9 million, while income from continuing operations for the same period
decreased to $2.2 million and resulted in diluted earnings per share from
continuing operations of $0.28. This compares to net revenue for the third
quarter of 2002 of $24.8 million with income from continuing operations of $3.0
million and diluted earnings per share from continuing operations of $0.38.

     Two notable items impacted the previous year's results. Interest expense
and other income during the third quarter of 2002 were positively impacted by a
$498,000 (net of income taxes) purchase price adjustment associated with the
Company's acquisitions of Crosby, Mead, Benton & Associates and Hook &
Associates Engineering, Inc.

     "We continue to have a growing flow of new projects for our residential
real estate services," said Aram Keith, Chairman and CEO of The Keith Companies.
"Internal growth in net revenue in this area was 8.5% for the third quarter of
2003 compared to 2002. Overall demand, however, in the industrial/energy segment
was significantly less than the prior year which creates challenging dynamics
for influencing our overall growth at this time. We do believe that the
industrial/energy segment may improve in the future.

     "We remain extremely diligent in the areas of our business that are within
our control, and we believe this is reflected in our continued strong margins,"
said Keith.

     Net revenue for the nine months ended September 30, 2003 decreased 1.9% to
$68.0 million, from $69.3 million for the nine months ended September 30, 2002.
Income from continuing operations for the nine months ended September 30, 2003
decreased to $5.3 million, and resulted in diluted earnings per share from
continuing operations of $0.67 compared to $6.6 million or diluted earnings per
share from continuing operations of $0.84 for the nine months ended September
30, 2002. As discussed above, interest expense and other income in 2002 were
positively impacted by a $498,000 (net of income taxes) purchase price
adjustment.





FINANCIAL POSITION

     The Company's September 30, 2003 balance sheet remains strong with cash and
securities of $28.2 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 $69.9
million or $9.16 per common share outstanding at September 30, 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 diluted earnings per share for the
fourth quarter of 2003 remains unchanged from the guidance previously provided.
For the full year, the Company estimates net revenue to range from $89.0 million
to $94.0 million, and forecasts diluted earnings per share to range from $0.88
to $0.93 based upon an estimated 8.0 million weighted average number of diluted
shares outstanding. For the fourth quarter, the Company expects diluted earnings
per share to range from $0.21 to $0.26.

     The Company also provided its initial guidance for 2004. 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
industrial/energy segment.

     "We are encouraged by the trends in our markets, which should provide solid
opportunities for growth going forward," said Keith. "The inventory of available
housing in our core California markets remains well below the levels required to
meet demand, which bodes well for the residential real estate market in general
and the level of activity we expect to see in this business area. In addition,
we are very encouraged by the recent pick-up in proposal activity for our
services in the industrial/energy segment. The unprecedented power outage in the
Northeast in August has prompted both utilities and businesses to address
shortcomings in their power generating and transmission capabilities. This can
create opportunities for our industrial/energy segment, and we believe we can
generate meaningful growth in this area in the coming year if the proposals turn
into awarded contracts."
