ISSUE: A public hearing regarding Angelo Street/EI Sombro Contractual Assessment
District No. 2000-3 (CAD No. 2000-3) was scheduled for September 20, 2001.
Additional time is needed to allow consideration of the project costs by the CAD
participants.
RECOMMENDATION: Continue the public hearing and continue consideration of approval
of Angelo Street/EI Sombro CAD 2000-3 to October 4, 2001.
FINANCIAL IMPACTS: The estimated total project cost is $201,604. The District has
authorized up to $1,000,000 per year for CADs in 2001-02. To date, the Board has
approved 2 CAD projects with a total project cost of $369,755. There is $630,245
remaining for other CAD projects.
AL TERNA TIVES/CONSIDERA TIONS: None
BACKGROUND: A group of 15 parcel owners on Angelo Street/EI Sombro in Lafayette
have requested that the District form a contractual assessment district for the purpose of
financing and constructing a public sewer system that will benefit their properties. The
Angelo Street/EI Sombro CAD meets all of the criteria for formation of a contractual
assessment district. The Board of Directors adopted a Resolution of Intention to form a
contractual assessment district on July 6, 2000. The proposed CAD project includes
approximately 1,255 linear feet of 8-inch sewer main, and five standard manholes that
will serve the proponents' 15 existing properties, all of which have existing homes
presently relying on septic tanks. A map showing the proposed boundary and the
proposed sewer location is presented as Attachment 1.

AUTHORIZE AWARD OF CONSTRUCTION CONTRACT TO INSITUFORM
TECHNOLOGIES, INC., FOR THE ORINDA TRUNK SEWER CURED-

REVIEWED AND RECOMMENDED FOR BOARD ACTION:
ISSUE: On September 5, 2001, sealed bids were received and opened for a construction
contract for the Orinda Trunk Sewer Cured-in-Place (CIP) Pipe Project, District Project
(DP) 5551. The Board of Directors must authorize award of the contract or reject bids
within 50 days of bid opening.
RECOMMENDATION: Authorize award of a construction contract.
FINANCIAL IMPACTS: Approximately $332,000 including contingency and construction
management.
AL TERNATIVES/CONSIDERATIONS: Reject all bids, which is not recommended.
BACKGROUND: The District began a trunk and interceptor sewer TV inspection program
in February of this year to evaluate corrosion problems in District concrete pipe. The
30-inch diameter reinforced-concrete pipe (RCP) carrying the sewer flow from the Lower
Orinda Pumping Station force main (see Attachment 1 for location) was one of the first
sewers inspected in the program. The TV inspection revealed extensive corrosion
throughout the sewer (approximately 1,020 ft.) with a serious localized problem (43 ft.)
downstream of the junction structure. Engineering staff fast tracked the design for
replacement of the worst section of the sewer, and this section was replaced in June.
Engineering staff has now designed a cured-in-place pipe liner repair for most of the
remaining 3D-inch diameter (-977 ft.) reinforced-concrete pipe.
A CIP liner is a trenchless repair method, which minimizes the amount of construction
impacts, specifically, in this case, traffic impacts on Camino Pablo. Traffic impacts will be
further reduced by requiring all work that needs lane closures to be done at night. District

staff will be on site at all times to insure proper traffic control. Day time work will consist
of monitoring of the pipe liner curing process, bypass pumping, and site restoration.
The plans and specifications were prepared by District staff. The engineer's estimate for
construction is $350,000. A total of two sealed bids were received and publicly opened on
September 5, 2001. A summary of bids received is shown in Attachment 2. Capital
Projects Division staff conducted a technical and commercial review of the bids and
determined that the bid submitted by Insituform Technologies, Inc., is the lowest
responsible bid at $234,435.
The District will administer the construction contract and will provide inspection, office
engineering, and shop drawing review. An initial allocation of $25,000 was made from the
Collection System Program Contingency Account. This project is included in the fiscal year
2001-2002 Capital Improvement Budget (CIB) under the Collection System Urgent Project
Program. The funds required to complete this project, as shown in Attachment 3, are
$307,000.
Staff has concluded that this project is exempt from the California Environmental Quality
Act (CEQA) under District CEQA Guidelines, Section 18.2, since it involves the repair of
an existing facility with no expansion of capacity. Authorization of the construction contract
for this project will establish the Board of Directors' independent finding that the project
is exempt from CEQA.
RECOMMENDED BOARD ACTION: Authorize the award of a construction contract in the
amount of $234,435 for completion of the Orinda Trunk Sewer CIP Pipe Project, DP 5551
to Insituform Technologies, Inc., the lowest responsible bidder.

ISSUE: Board of Directors' authorization is required for the General Manager to e
professional services agreements in amounts greater than $50,000.
RECOMMENDATION: Authorize the General Manager to execute an amendment to an
agreement with Wilson, Ihrig & Associates, Inc., adding $20,000 for professional
consulting services in connection with the noise and vibration measurement and provide
construction support during the installation of the trunk sewer on Mangos Drive and
Estero Drive in the City of San Ramon. The addition will bring the total contract amount
to $62,500. The prior contract amount of $25,000 was approved by the Board of
Directors at the award of the construction contract for the Dougherty Valley Tunnel and
Trunk Sewer Project on July 5, 2001, and was subsequently increased to a total of
$42,500.
FINANCIAL IMPACTS: The cost will be re-allocated from the existing authorized project
contingency budget.
ALTERNATIVES/CONSIDERATIONS: In order to comply with the City of San Ramon
encroachment permit, noise and vibration monitoring and related activities must continue
through the construction duration. There are no viable alternatives.
BACKGROUND: The construction contract for the Dougherty Valley Tunnel and Trunk
Sewer Project was awarded on July 5, 2001, after a delay of more than two years
because of various litigations, including litigation between the District and the City of San
Ramon over the issuance of an encroachment permit. The litigation was ultimately
resolved by a negotiated settlement agreement, and the encroachment permit was issued
by the City including a requirement on vibration and noise monitoring and mitigations. A
contract in the amount of $25,000 was negotiated with Wilson, Ihrig & Associates, Inc.
prior to the start of construction. The scope of that contract was to provide

AND TRUNK SEWER PROJECT, DISTRICT PROJECT NO. 5902
preconstruction baseline and construction measurements for noise and vibration. The
District has already performed the baseline monitoring. It has become clear that a much
more extensive program than was originally anticipated is required. It is in the District's
best interests to provide a more extensive program. More monitoring stations have been
installed, and the consultant has been requested to respond to numerous inquiries,
including additional field visits.
It is expected that continuing support by the consultant during the construction activities
will be required. Our current estimate for these efforts is $62,500. If the situation
continues to change, this amount may increase. These costs will be passed through to
the developers who are funding the Dougherty Valley Tunnel and Trunk Sewer Project.
RECOMMENDED BOARD ACTION: Authorize the General Manager to execute an
amendment to the agreement with Wilson, Ihrig & Associates, Inc. at an additional cost
not to exceed $20,000 for professional consulting services in connection with the
Dougherty Valley Tunnel and Trunk Sewer Project, District Project No. 5902, which brings
the total agreement cost to $62,500.
