EXHIBIT 2.2

            Amendment No. 1 to the Agreement for the Acquisition of
           All Outstanding Stock of ESI, Engineering Services, Inc.

     This Amendment No. 1 to that certain  Agreement (the "Original Agreement")
for the Acquisition of all  outstanding stock of ESI, Engineering Services, Inc.
("ESI") by and among the Keith Companies, Inc. ("Buyer"), Lynn C. Cannady, Glenn
I. Chase and Stephen J. Lane (collectively, "Sellers" or  individually, a
"Seller") is entered into as of June 3, 1999 to amend some of the provisions of
the Original Agreement as follows:

1.   Adjustment for Present and Future Stock Splits.  All references to: (a) a
number of shares of Buyer's common stock and (b) a number of options or rights
to acquire or sell Buyer's common stock shall be automatically reduced in the
event Buyer implements a reverse stock split and automatically increased in the
event Buyer implements a stock split, in both cases in proportion to the reverse
stock split or the stock split as the case may be.  All references to: (a) a
price at which Buyer's common stock may or must be sold or purchased, and (b) a
price at which options or rights to acquire or sell Buyer's common stock may or
must be sold or purchased shall be automatically increased in the event Buyer
implements a reverse stock split and automatically decreased in the event Buyer
implements a stock split, in both cases in proportion to the reverse stock split
or the stock split as the case may.  Regardless of when this Amendment is
executed by Buyer and the Sellers, it shall be effective immediately prior to
the implementation of Buyer's 2.7 to 1 reverse stock split.

2.   Removal of Restrictive Legend.  Within three business days of the
effectiveness of Buyer's Initial Public Offering of Buyer's common stock and
after receipt  by Buyer (or Buyer's Transfer Agent) of Sellers' certificates
representing the shares of Buyer's common stock issued to Seller's pursuant to
Section II.E.1., Buyer shall deliver to Sellers new certificates that (a)
reflect the 2.7 reverse stock split implemented by Buyer in connection with its
Initial Public Offering, (b) to the fullest extent authorized by applicable
federal and state securities laws, including Rule 144 promulgated under the
Securities Act of 1933,  are free of any legend which restricts the free
transferability of the shares represented by such certificate, and (c) are in a
form equivalent to that of certificates delivered to purchasers of the Buyer's
common stock in its Initial Public Offering.

3.   Two Hour Right of First Refusal.  For a period of 180 days following
Buyer's initial public offering, each of Sellers shall, prior to transferring
any of the shares represented by the certificates issued pursuant to paragraph 2
above, notify between the hours of 8:00 a.m and 3:00 p.m. (Pacific Time) by
telephone call and by facsimile both of the persons indicated below (the
"Underwriters' Representatives") of: (a) Seller's offer (the "Offer") to sell to
the designee of the Underwriters' Representatives the number of shares of
Buyer's common stock that Seller wishes to sell (the "Offered Shares"), (b) the
identity of Seller, and (c) a method for reaching Seller within the two hour
period then following. If either one of the Underwriters' Representatives do not
agree within two hours of the time the Offer was communicated to purchase the
Offered Shares at the market price (or the bid price , if applicable) in effect
at the time the Offer was communicated, then Seller shall be free to sell the
Offered Shares without restriction. The Offer shall be deemed to have been
communicated when Seller has actually spoken with one of the Underwriters'
Representatives and has successfully transmitted to both


Underwriters' Representatives a facsimile giving the details specified above;
provided, however, that each of the Underwriters' Representatives shall
exercise good faith in responding to any messages left by any Seller. Subsequent
to the execution of this Amendment, other Underwriters' Representatives may be
identified in writing by either of the Underwriters' Representatives pursuant to
the Notice provisions of the Original Agreement. The Underwriters'
Representatives shall be:


     Henry K. S. Wilson
     Telephone:             (415) 954-8343
     Fax:                   (415) 954-8335

     John Merriman
     Telephone:             (415) 954-8336
     Fax:                   (415) 954-8361

4.   Accelerated Vesting of Options.   The options issued to each of the Sellers
pursuant to Section II.E.2 (but no other options) shall immediately vest and
become exercisable upon the effectiveness of Buyer's initial public offering
notwithstanding any other term or provision to the contrary.  The references to
the date of October 1, 1999 in the second sentence of the second paragraph of
Section II.E.2. and the date of October, 1999 in the last sentence of the second
paragraph of Section II.E.2. are hereby deleted and replaced with "the date of
Buyer's initial public offering."

5.   No Other Terms Amended.  No other terms of  the Original Agreement are
amended by this Amendment No. 1.
