SITUATION
A. Summary and Recommendation
Bids were opened on June 25, 1995, for the installation of drainage improvements on Calle
Delgado. Bob Wetzel Concrete, Inc., was the low bidder at $9,624. Staff is recommending
award of the bid to the low responsible bidder, Bob Wetzel Concrete, Inc.
B. Background
In August, 1994, the City Council authorized staff to proceed with geotechnical testing and
preparation of construction plans to correct a problem with ponding water in the street
adjacent to 27171 Calle Delgado. The geotechnical report concluded that ponding was at the
center of a very deep subsurface consolidation. This conclusion is bome out by the
observance of settlement of the adjacent homes and concrete slabs which lie between the
street and the slope at the rear of the homes. The geotechnical report did not address
recommendations for solving the settlement problem on private property. It may be advisable
for the private property owners to pursue recommendations to mitigate their settlement
problem also in view of the geotechnical report conclusion that settlement is likely to continue
to occur indefinitely.
The City contracted with Elmer Christiansen & Associates to prepare plans to solve the
ponding problem. Originally, Calle Delgado was constructed to drain in a westerly direction,
however, the street has gradually settled to form a low spot in front of 27171 Calle Delgado.
Rather than reconstruct the curb, gutter and sidewalk to regain the original grade, it has been
decided to place a catch basin and a storm drain lateral at the created low point. This solution
will minimize the costs of correction of the ponding problem and will be effective in carrying

off water, even if the settlement continues to occur. The design will not create any adverse
conditions with respect to the adjacent properties, nor will it preclude additional remediation
to the adjacent properties. Adjacent property owners and the homeowners association have
been notified of the proposed City project and have received copies of the geotechnical
report.
On June 6, 1995, the City Council approved the plans and specifications for installation of the
drainage improvements on Calle Delgado and authorized staff to receive bids. Bids were
received on June 25, 1995, as follows:
1. Bob Wetzel Concrete, Inc . ............................ $ 9,624.00
2. Steve Capello Construction ........................... 10,388.00
3. Brongo Construction ................................ 12,387.70
The engineer's estimate was $8,500. The 13% difference in the low bid and the engineer's
estimate can be explained by the difficulty in estimating very small jobs. The smaller the
project, the more likely contractor costs, such as office overhead, bonding, mobilization and
other items which are difficult to estimate will drive up costs.
COMMISSION/BOARD REVIEW AND RECOMMENDATIONS
Environmental Administrator reviewed the proposed project on January 24, 1995 and approved the
release of the project for preparation of bid documents/specifications pursuant to City Council Policy
418.
