Background
The proposed roads where pavements will be improved are located throughout the county as shown on the location map (see Attachment A), and as listed below. These segments were selected based on the available funds, their high level of use, and to provide pavement improvements on corridors that could benefit from the relatively lower cost pavement preservation methods proposed with this contract. Additionally, the roads were selected since they are not eligible or unlikely to be competitive for federal funding.
CR 29A from I-505 to CR 92E
CR 92E from CR 29A to CR 29
CR 29 from CR 92E to CR 102
CR 89 from Winters city limit to CR 31
CR 89 from CR 28 to CR 26
CR 87 from S.R. 16 to south of CR 19A
CR 27 from I-505 to west of CR 92D
CR 88 from CR 6 to CR 4
CR 4 from CR 88 to CR 99W
CR 99W from CR 4 to CR 89
CR 89 from CR 6 to CR 99W
CR 6 from CR 88 to I-5.
On road segments where the pavement has far exceeded its design life, pavement will be replaced with an HMA treatment. This treatment work includes two basic strategies:
- Grind and remove the top layer of pavement and overlay with asphalt concrete.
- Completely pulverize pavement in place, grade, compact and pave with asphalt concrete.
Paving work will be followed by shoulder grading to conform new pavement to existing grades and driveways.
On road segments where the pavement life can be extended, the treatment will include digging out and replacing failed areas, crack sealing, and chip sealing. All of the pavement improvements will be followed by striping work.
The project is expected to take approximately 60 working days to complete. Road closures will be required to complete the work safely on CR 29A from I-505 to Buckeye, CR 89 from Winters city limit to CR 31, CR 89 from CR 26 to CR 27, and CR 6. The contractor will be required to provide access to residences and businesses along closed roads at all times. Advance notification signs will be placed to direct motorists to alternate routes during the closures. All other roadwork will be under traffic control that will involve lane closures, and minor delays to traffic during the work day. |
| Collaborations (including Board advisory groups and external partner agencies) |
| The City of Winters will issue an encroachment permit for detour signage in the City. |

Explanation (Expenditure and/or Revenue) |
| Further explanation as needed: |
The project is budgeted in next year’s recommended Road Fund budget. Account 503040 “Roads and Improvements” in the 2017-18 Recommended Road Fund budget contains sufficient budget authority to allow the project to be awarded in July 2017, following bidding, and following adoption of the 2017-18 Recommended Budget. The 2016-17 General Fund monies approved for paving work are included as part of this project and have already been transferred to the Road Fund. The 2017-18 Final Adopted 2017/18 Road Fund budget will be adjusted as required, based on actual bid results.
