Robert Bein, William Frost and Associates in the amount of $35,320
to provide the engineering services for the design of the El Modena-
Irvine,Channel improvements between•the I-5 Freeway and downstream

_2. Solicitation of proposals and execution of a professional services
agreement for.the .geotechnical services associated with the El
Modena -Irvine Channel design.
BACKGROUND:
As a part of the development of the Auto Center Retarding Basin into two
developable building sites, it will be necessary to complete certain
public improvements as follows:
1. Extension of Auto Center Drive easterly approximately 600+ feet.
2. Extension of the 81 -inch diameter storm drain easterly from its
present terminus to, and connection with, the El Modena -Irvine
Channel.
3. -The extension*,of"the E1—Modena-Irvine Channel mainline improve-
ments southerly between the Santa Ana (I-5) freeway and Michelle

Items number 1 and 2 are currently in progress and this action item

The consultant proposes to perform the tasks outlined in Work Items
through 11 for a fee of $31,320 plus reimbursable costs in the estimated
amount of $4,000.00.
1..
Staff did not solicit proposals from other consultants because the firm
of Robert Bein, William Frost and Associates previously completed all of
the channel design upstream of the freeway for.the City, as.well as all
of the preliminary studies of the subject channel design project. The
fee as submitted is a reasonable amount to complete the tasks as
outlined'in the proposal. As indicated within the proposal, the geo-
technical servicesare not inlcuded and it is suggested that the Cit
request proposals for these services. It is estimated that the
geotechnical services for this segment of channel design will cost about
$15,000 - $17,000.
It is staff's desire to commence this channel design work at the
-oarliest practical date so that a construction contract can be awarded
3 later than May 1990. This will allow five months of construction
time prior to the 1990 wet season. As you are aware, this project
location lies totally within the city limits of Irvine and is a Regional
Flood Control Facility under the jurisdiction of the Orange Count
Environmental Management Agency. The intent of this project is to
eliminate the backwater effects within the F07 Channel northerly of the
I-5 freeway and reduce the need for the Auto Center Retarding Basin.
In order to proceed with this project design and construction, the
following actions must be completed:
�1. Authorization to hire the firm of Robert Bein, William Frost and
Associates to provide the engineering services for the design of
the El Modena -Irvine Channel as described above for the fee of
$35,320.00.
2. Solicit proposals and award a contract for the required geotechnical
engineering services associated with the channel design. Estimated
cost is $15,0'00 to $17,000.
3. Authorize a supplemental 1989-90 budget appropriation from the
appropriated reserves of the Capital Improvement Fund.in the
following amounts for said project:
