Peterson, Acting Public Works Di ��y_" William T. Hetland, Utilities Director aif Prepared by: Morris D. Witbeck, Engineering Assistants w' SUBJECT: Waterline Improvement Project: Higuera St. - Broad to Osos, City Plan No. S-05P CAO RECOMMENDATION: By motion, approve the plans and specifications for Waterline Improvement Project: Higuera St. - Broad to Osos, City Plan No. S-05P, and authorize soliciting of bids and contract .award by the CAO if the lowest responsible bid is within the Engineer's cost estimate. DISCUSSION: The waterlines in the downtown area are very old and in a deteriorated condition. Frequent breakages disrupt service. These lines are also undersized and do not provide adequate fire flow to meet current standards. The replacement of this waterline is also a condition of the building permit for the construction of the "Copeland Project" at 879 Higuera St. to provide adequate fire protection. Another condition of the "Copeland Project" is participation in the cost of the project, the amount of which has not been determined at this point. As this project will be in the core of the downtown, a number of mitigating measures and stringent requirements will be included to minimize the disruption to business activities (see attachments) . The conditions are designed to ensure that Thursday night activities will not be impacted, and that parking will be maintained to the maximum extent possible. During construction, the City proposes to provide special promotions for the business community affected by this project. This program is still being worked on by staff, and should be ready for Council review prior to December. The BIA will be a participant in designing the program. CONCURRENCE: Staff has discussed this project with the BIA. Staff has met with the Thursday Night Activity Committee and included conditions in the project specifications to allow the Thursday night activities to continue, and be impacted as little as possible. The winter timing of the project was recommended by the BIA after surveying their membership. The BIA has reviewed the attached list of conditions and n�Hil►�►►►�IIIIIII�IIiI����Il city or San lugs OBISPO - Hia; COUNCIL AGENDA REPORT we have received concurrence from Lynn Block. Weather problems and impacts were explained. The Community Development Department has determined that this project is categorically exempt from further environmental review. FISCAL IMPACT: Engineer's Estimate: $150, 000 7% Contingencies: 10, 000 Potential Bonus: 20. 000 Total: $180, 000 In order to encourage early completion of the project, a bonus will be paid to the Contractor at the rate of $2, 000 for each day earlier than the completion date that the project is finished, up to a maximum of $20, 000. Failure to finish on time or to work on a working day can be penalized at a cost of $1, 000. 00 per day. The Engineer's Estimate for the project is $150, 000. The CIP for 1992/93 (page E-7) includes $600, 000 for water main improvement projects. To date, $94, 000 has been approved for other water distribution projects, leaving $506, 000 to support this project. The City Council, at the June 30, 1992 meeting, determined that utility projects go forward based on their independent funding.
