          THE KEITH COMPANIES REPORTS SECOND QUARTER RESULTS AND STRONG
                     INTERNAL GROWTH IN REAL ESTATE SERVICES

IRVINE, CA (August 7, 2003)...The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced financial results for
the second quarter ended June 30, 2003.

     Net revenue for the three months ended June 30, 2003 decreased 3.7% to
$22.8 million, while income from continuing operations for the same period
decreased to $1.7 million and resulted in diluted earnings per share from
continuing operations of $0.22. This compares to net revenue for the second
quarter of 2002 of $23.7 million with income from continuing operations of $2.1
million and diluted earnings per share from continuing operations of $0.26.

     "Even though our results were lower than the prior year," said Aram Keith,
Chairman and CEO of The Keith Companies, Inc., "the current quarter results for
both net revenue and diluted earnings per share were in line with our
expectations. These decreases from the prior year were mainly due to the
continued weakness in the industrial/energy segment. We still believe that this
segment will be an important long term growth vehicle for us."

     Net revenue for the six months ended June 30, 2003 increased 1.5% to $45.1
million, from $44.5 million for the six months ended June 30, 2002. This
increase was primarily due to increased net revenue derived from real estate
services and additional net revenue generated from the acquisition of ALNM
Group, Inc. (the Company acquired ALNM Group, Inc. effective March 1, 2002).
These increases were partially offset by lower net revenue from our
industrial/energy segment. Income from continuing operations for the six months
ended June 30, 2003 decreased to $3.1 million, and resulted in diluted earnings
per share from continuing operations of $0.39 compared to $3.6 million or
diluted earnings per share from continuing operations of $0.46 for the six
months ended June 30, 2002.

        "We continue to see strong demand for our services in the residential
real estate market," said Keith. "For the quarter and six months ended, this
area of our business posted an 8.8% and 12.0% internal growth in net revenue
from the prior year, respectively, with strength in both the Northern and
Southern California markets. We are seeing a good mix of real estate projects
from new master planned communities that are in the process of being planned,
designed and constructed, and from more mature communities that now require the
development of schools, community centers and other ancillary facilities."

FINANCIAL POSITION

     The Company's June 30, 2003 balance sheet remains strong with cash and
securities of $27.0 million, a current ratio of 4.50:1, a debt to equity ratio
of 0.00:1 (excluding issuable common stock) and shareholders' equity of $67.6
million or $8.87 per common share outstanding at June 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
third and fourth quarters of 2003 remains unchanged from the guidance previously
provided. For the full year, the Company estimates net revenue to range from
$90.0 million to $97.0 million, and forecasts diluted earnings per share to
range from $0.87 to $0.97 based upon an estimated 8.0 million weighted average
number of diluted shares outstanding. Broken out by quarters, the Company
expects the following ranges for diluted earnings per share: $0.27 to $0.32 for
the third quarter; and $0.21 to $0.26 for the fourth quarter.

     "We have a strong pipeline of work from our residential real estate
clients, which gives us comfort on the second half of 2003," said Keith. "Our
homebuilding clients see good opportunities to continue growing their business,
and we are well positioned to continue benefiting from their expansion efforts."
