RECOMMENDATION
title
Director of Public Works requests approval of a Budget Transfer for Berryessa Knoxville Road FLAP 1 as follows: (4/5 vote required):
1. Increase appropriations by $30,000 in Measure T Non-Operating Special Revenue Fund (Fund 2440, Org 1220053) (M-T SRF) offset by use of its available fund balance; and
2. Increase appropriations by $30,000 in Berryessa Knoxville Road FLAP 1 Seal Project (Fund 2040, Org 2040500, Project 22027) offset by transfer from M-T SRF.

EXECUTIVE SUMMARY
In 2023, the Department of Public Works will pursue three (3) Roadway Seal projects within Napa County to maintain the pavement on Redwood Road (from the City of Napa limits to the intersection with Mount Veeder Road), on American Canyon Road East (from the City of American Canyon limits to the City of Vallejo limits), and on Berryessa Knoxville Road within the FLAP 1 limits (beginning at Spanish Flat Loop Road and ending at the intersection with Pope Valley Road). These three (3) seal projects have been combined into a single project to achieve an “economy of scale”, with the intention of obtaining better material and labor prices as well as a timely construction schedule. The three (3) roadways above will be evaluated for the proper road treatment in 2022, with construction ensuing by the Spring of 2023 and completed by the Fall of 2023. Additional funding is requested for Berryessa Knoxville Road FLAP 1 (Project 22027) to complete the preliminary design and prepare bid documents for construction.
FISCAL & STRATEGIC PLAN IMPACT
|
Is there a Fiscal Impact? |
Yes |
|
Is it currently budgeted? |
No |
|
Where is it budgeted? |
Funding will come from M-T SRF. Project is budgeted in Berryessa Knoxville Road FLAP 1 Seal Project (Fund 2040, Org 2040500, Project 22027) . |
|
Is it Mandatory or Discretionary? |
Discretionary |
|
Discretionary Justification: |
The proposed project will preserve the existing pavement and prevent the need for more strenuous and expensive road repairs in the future. The requested Budget Transfer is for the preliminary design and preparation of bid documents for the Berryessa Knoxville Road Seal project that would be constructed in 2023. |
|
Is the general fund affected? |
No |
|
Future fiscal impact: |
Design will begin in Fiscal Year 2022-23 and construction will begin during the Fiscal Year 2022-23. Construction is likely to continue into Fiscal Year 2023-24. |
|
Consequences if not approved: |
If not approved, there will not be enough money within Project 22027 to complete the preliminary design and the bid documents to construct roadway repairs on Berryessa Knoxville Road. This project will prevent the road from degrading and help the County to avoid costly repair and resurfacing work in the future. |
|
County Strategic Plan pillar addressed: |
Healthy, Safe, and Welcoming Place to Live, Work, and Visit |
|
Additional Information |
Sealing Berryessa Knoxville Road is required by the Federal Highway Administration (FHWA) as they provided a grant to reconstruct this road in 2015; further, to maintain eligibility for future FHWA grants it is imperative that the County provides maintenance to this road (for additional information refer to the Background and Discussion section). |
ENVIRONMENTAL IMPACT
ENVIRONMENTAL DETERMINATION: Consideration and possible adoption of a Categorical Exemption Class 1: It has been determined that this type of project does not have a significant effect on the environment and is exempt from the California Environmental Quality Act. [See Class 1 (“Existing Facilities”) which may be found in the guidelines for the implementation of the California Environmental Quality Act at 14 CCR §15301; see also Napa County’s Local Procedures for Implementing the California Environmental Quality Act, Appendix B.]
BACKGROUND AND DISCUSSION
Berryessa Knoxville Road is located in the most eastern portion of the County, it provides access along the west side of Lake Berryessa, and it connects Napa County to Lake County. The Napa County General Plan Circulation Element classifies Berryessa Knoxville Road as a two (2) lane arterial road that provides access between State Route 128 (Sage Canyon Road) and Pope Canyon Road.
Based upon available records, Berryessa Knoxville Road was originally constructed in the mid 1950’s when the U.S. Bureau of Reclamation built the Monticello Dam. In 2015, the Federal Highway Administration (FHWA) reconstructed a portion of Berryessa Knoxville Road, also known as FLAP 1, which spans from Spanish Flat Loop Road to Pope Canyon Road, approximately eight (8) miles.
In 2018, Napa County voters passed a ½-cent sales tax, known as Measure T, to finance the maintenance and repair of existing roads within the Napa County limits. Experience demonstrates that it is essential to perform preventative maintenance to prolong the life span of a roadway at a lower cost, rather than reconstructing a road after it has failed at 10 to 30 times the cost of preventative maintenance.
The FHWA is considering providing federal funding for the reconstruction of the FLAP 2 portion of Berryessa Knoxville Road (which spans from State Route 128 to the beginning of FLAP 1), with reconstruction possibly occurring in 2027. Given that the FLAP 1 portion of the road was reconstructed in 2015 and the County is applying for federal funding to reconstruct an additional section of Berryessa Knoxville Rd. under FLAP 2, resurfacing the FLAP 1 area will ensure compliance with the County’s Pavement Management Program (PMP) and is consistent with Napa County’s response in the FLAP 2 application to FHWA that the County can afford to maintain, but not reconstruct, Berryessa Knoxville Road.
To properly maintain Berryessa Knoxville Road, the Department of Public Works staff is proposing a single chip seal on the road surface topped with a fog seal. This type of surface treatment will ensure that minor cracks, that have developed since the road’s reconstruction, will not develop any further and other surface deformities could be sealed and protected from exposure. It is the Department of Public Works intention to maintain Berryessa Knoxville Road FLAP 1 as part of the 2023 Seal Projects and we request additional funding for the design and bid phase of this project.
