McCluskey,Public Works Director-' Prepared by: Daniel Van Beveren, Civil Engineer-AIA59 Joe McDermott, Streets Supervisor SUBJECT: 1999 Street Microsurfacing Project Specification No. 90007 CAO RECOMMENDATIONS: 1. Approve plans and specifications for the 1999 Street Microsurfacing Project, Specification No. 90007. 2. Authorize staff to advertise for bids. 3. Authorize the CAO to award the contract if the lowest responsible bid is within the project budget of$506,000. DISCUSSION The City Council adopted the City's Pavement Management Plan(PMP) on April 14, 1998. One key objective of the PMP is to divide the city into eight maintenance areas and then each year focus on pavement maintenance within one of these eight areas. PMP policy states that maintenance planned for any street should be based on the condition of that street and the budget available. Typically, an annual rehabilitation project consists of reconstructing or resurfacing selected streets within the scheduled maintenance area An annual microsurfacing project should then reseal all remaining streets within the maintenance area Maintenance Area 2 is scheduled for 1999. The attached listing and map show all the streets included in the proposed project. This project is similar to the 1998 microsurfacing project but with a few key changes. Specifications have been modified to include more stringent inspection requirements for the quality of the asphalt mix used in the microsurfacing. Furthermore, provisions have also been added to the specifications that will result in the permanent thermoplastic pavement striping and markings to be applied to the pavement within a shorter period of time following the placement of the microsurface. Lastly, and perhaps most important, construction will be scheduled during the summer instead of the late fall as was the case with the 1998 project It is critical that this project be bid in the early spring. First, it is highly preferable to place microsurfacing in the summer and early fall. As Council will remember, the last project was applied in late November and early December. Not only is this the height of the holiday shopping season, but the days are short and the newly surfaced streets are very dark at night (which comes early) until striping is applied. Furthermore, the quality of the microsurface is C2-1 Council Agenda Report- 1999 Street Microsurfacing Project Page 2 somewhat dependent on the temperature of the air and the pavement to which it is applied. The results tend to be considerably better when the microsurface is applied during warmer weather. Lastly,there are only two.known contractors in California that perform microsurfacing work,and their schedules for summer and early fall will be filling up quickly. As discussed above, there were a few problems associated with last year's Area 1 project. This resulted in one street in particular, Mill Street from Santa Rosa to California, now having a substandard microsurface. For this reason, that portion of Mill Street will be included in the 1999 project to correct the situation. Two other streets which are also in Area 1, California Boulevard from Taft to Marsh, and Johnson Avenue from Buchon to Bishop, have also been added to this year's microsurfacing project because of budget restraints which would not allow them to be included in the street rehabilitation project. CONCURRENCES A Notice of Exemption was filed and approved by the Community Development Department for environmental clearance. FISCAL IMPACT Contract Award and Budget Availability Resource requirements: Under the pavement management plan, we should spend about $458,000 annually for sealing (which is budgeted as an operating program expenditure); and about $1.5 million annually for resurfacing/reconstruction (which is budgeted as a CIP project). This is the level budgeted for 1998-99, and will be the proposed level for the 1999-01 Financial Plan. Work schedule and budget. As discussed above, work under this contract will not begin until July or August. However, in order to ensure contractor availability, we plan to award this contract in April, which is before the Council will have formally adopted the budget for 1999-00. While it is technically possible that complications could arise between the budget the Council ultimately adopts for 1999-00 and the contract amount, we do not believe this is likely for two reasons: Under the pavement management plan, maintenance (sealing) is a higher priority than resurfacing/reconstruction. As such, if the Council ultimately decides to fund pavement work at a lower level than set forth in the pavement management plan, reductions should come from resurfacing/reconstruction, not sealing. The City's bid terms provide significant flexibility in reducing or expanding the scope of work after contract award. As such, should the Council appropriate less than $458,000 for sealing, we would simply amend the contract. However, as noted above,this is highly unlikely, since any potential reductions should come from resurfacing/reconstruction,not sealing. In summary, this approach ensures contractor availability for the summer,and better matches C2-2 Council Agenda Report- 1999 Street Microsurfacing Project Page 2 appropriations with expenditures. While there is a remote potential for a budget conflict,we believe this is highly unlikely for the reasons discussed above. Funding We are recommending a$506,000 program.for 1999, summarized as follows: Engineer's estimate 481,800 Contingency of 5% 24.200 Total $506,000 As discussed above,the proposed work for 1999 includes all of Area 2 as well as some extra work in Area 1. For this reason,the 1999 program will be larger than the annual target of $458,000. This will be funded as follows: 1999-00 sealing budget 458,000 Balance remaining from 1998-99 sealing budget 48,000 Total $506,000 Base contract quantities are tailored to the budget available and should cover microsurfacing of about 16 street kilometers. Consequently, the engineer's estimate is very close to the budget available. If unit prices are higher or lower than expected, contract amounts will be adjusted accordingly. .
