RECOMMENDED ACTION:
Adopt Resolution No. 2006-203 to reject bids received for the Erosion Repairs and Drainage
Improvements, Carrillo Ranch Historic Park, City Project No. 45011; approval of re-bid plans and
specifications; authorization to re bid; and appropriation of additional funds to the project.
ITEM EXPLANATION:
Several storm events in early 2005 resulted in extensive erosion at Leo Carrillo Ranch Historic Park
(Exhibit 3, Erosion Photos). In order to repair the erosion and to address the ongoing drainage issues at
the park, the City Council adopted Resolution No. 2005-374 on December 20, 2005 approving the plans
and specifications and authorizing the advertisement for bids for erosion repairs and drainage
improvements at the park. The proposed erosion repairs and improvements included the following:
Supplemental stabilized decomposed granite to re-establish grades for positive drainage
Minor grading to redirect water to minimize erosion
- Additional catch basins and storm drainage to collect and direct run-off
Installation of concrete and cobble lined swales to direct water away from the existing historic
buildings and pedestrian pathways
- Applications of stabilizer solutions to stabilize previously installed non stabilized decomposed
granite
The project was advertised and 3 bids were received on April 20, 2006. The table below lists the bidders
and the corresponding bids received for the project.
Contractor Name/City

Total Amount

$329,243.50
$464,740.00
Shortly after the bid opening, the apparent low bidder, Romero General, "withdrew" their bid due to
several errors in calculations in filling out their bid. After review by the City Attorney's office and the
Purchasing Department, it was determined that Romero General had satisfied the requirements
necessary to withdraw their bid. Therefore, staff recommends to the Council that Romero be relieved of
their bid. This would establish Zondiros Corporation, as the next responsive bidder for the project.

Because the City only received 2 responsive bids, and the bid costs appear to be excessive, staff is
recommending that the City re-bid the project. Because costs continue to rise, staff is also
recommending reducing the scope of the project to help lower the cost as follows:
• Replace originally proposed cobble-lined concrete swale with underground perforated pipe.
• Use a lower cost decomposed granite stabilizing technique.
• Eliminate decomposed granite stabilization in certain areas that are less steep and therefore
less prone to erosion.
• Enlist the Public Works Department to assist in:
o Partial dredging of the adjacent creek that has filled up with soil from erosion.
o Tree removals within the creek.
o Repair of irrigation caused by proposed underground drainage installation
The attached Resolution will approve the plans and specifications and authorize re-bidding. Although
some of these changes may potentially reduce the degree of erosion protection, staff feels the measures
outlined in the re-bid design will still substantially increase the protection of the site and result in
decrease closures from future erosion damage. Because of the variables related to future storm
severities, it is unknown how much longer the original design would last compared to the proposed re-
design.
Despite the reduced scope, additional funds of $87,000 will still be required to cover the estimated cost
of the re-designed project. The new engineer's estimate for the re-design is $262,000 (refer to Fiscal
Impact for more information).
ALTERNATIVES:
Although staff is recommending re-bidding, Council has the option to award the bid to the Zondiros
Corporation as submitted (Alternative 2 below).
1. Reject the bids received April 20, 2006 and authorize staff to re-bid the project with the reduced
scope of work. Appropriate additional funds in the amount of $87,000 to the project from the
General Capital Construction (GCC) fund.
2. Proceed with original design and award the bid to Zondiros Corporation in the amount of
$329,243.50 and appropriate an additional $187,244 from the GCC fund to the project to cover the
bid amount plus a 10% construction contingency.
FISCAL IMPACT:
There is currently $180,000 of GCC funds appropriated to the project. $5,000 has been used to date for
design, leaving a balance of $175,000. Additional funds will be required under each alternative as shown
below:
Alternative 1 Alternative 2 Difference

(Recommended)
Construction $238,000 $329,244 $91,244
Contingency +24.000 +33.000 +9.000
