Project Description

The Napa Valley Transportation Authority (NVTA) operates Vine Transit, which provides bus, community shuttle, and paratransit services for Napa County. NVTA proposes to construct a new public transit maintenance facility for Vine Transit, to replace the currently leased site at 720 Jackson Street in Napa. The project would include:

•       Maintenance building with up to eight (8) bays
•       Administration building
•       Parking for 93 public transit vehicles up to 60 feet long
•       75 visitor and employee parking spaces
•       Compliance with all building and design standards and regulations including American with Disabilities Act (ADA)

The conceptual site plan is reproduced at the end of this notice. The proposed project would replace an existing deficient maintenance yard that is leased from the City of Napa. The present facility located at 720 Jackson Street in Napa is insufficient for Vine Transit’s existing service and cannot accommodate future growth because it does not have enough bus maintenance bays or parking or sufficient space for a modern bus wash. It further cannot accommodate visitor or employee parking. 

Purpose of this Notice of Preparation

NVTA circulated an Initial Study-Mitigated Negative Declaration in October 2016 to analyze this same project in compliance with the California Environmental Quality Act (CEQA). Subsequent to the adoption of the Initial Study-Mitigated Negative Declaration in 2016, NVTA decided to prepare an Initial Study and an environmental impact report (EIR) to further evaluate areas of known public controversy. Therefore, in accordance with the State CEQA Guidelines (14 California Code of Regulations [CCR] Section 15082), NVTA has prepared this notice of preparation (NOP) to inform agencies and interested parties that an EIR will be prepared for the above-referenced project. The purpose of an NOP is to provide sufficient information about the proposed project and its potential environmental impacts to allow agencies and interested parties the opportunity to provide a meaningful response related to the scope and content of the EIR, including mitigation measures that should be considered and alternatives that should be addressed (State CEQA Guidelines 14 CCR Section 15082[b]).

Potential Environmental Impacts

Pursuant to CEQA and CCR Section 15064, the discussion of potential effects on the environment in the EIR shall be focused on those impacts that NVTA has determined may be potentially significant. Based on the preliminary findings of the Initial Study prepared for the project, the Napa Valley Transportation Authority anticipates that the project may result in potentially significant impacts in the following topic areas, which will be further evaluated in the EIR:

•       Biological Resources
•       Hydrology and Water Quality
•       Transportation/Traffic


Based on the Initial Study findings, the project would have no impacts or less than significant impacts (either with or without mitigation) on:


Land Use Planning

Agricultural Resources

Mineral Resources

Air Quality


Cultural Resources

Population and Housing

Geology and Soils

Public Services

Greenhouse Gas Emissions


Hazards and Hazardous Materials

Utilities and Service Systems

The Initial Study may be viewed online at or at NVTA offices, 625 Burnell Street, Napa, California during regular business hours.

Review and Comment Period

NVTA is requesting comments from your agency on the scope and content of the project’s environmental information that is germane to your agency's statutory responsibilities. If your agency will be issuing a permit in connection with the proposed project, your agency will need to use the EIR prepared by NVTA when considering your permit or other project approval.

In addition to agencies, other interested parties may also provide NVTA with written comments on topics to be addressed in the EIR for the project, including, but not limited to, potential project impacts, mitigation measures, and project alternatives. Due to the time limits mandated by State law, your response must be sent at the earliest possible date and not later than 30 days after receipt of this notice. The review period for comments pertaining to this NOP extends from May 11, 2017, to 5:00 P.M. on June 12, 2017. Please send all comments to or by mail to:
