|
Is the general fund affected? |
No |

Future fiscal impact: |
Construction of a new sewer lift station will provide greater opportunity for homes to be rebuilt and new service connections. |
|
Consequences if not approved: |
Replacement of the Woodhaven Ct. Lift Station will not be constructed and the District will not be able to move the project forward.

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
The Napa Berryessa Resort Improvement District (“District”) is a special district of the State of California organized under the Resort Improvement District Law (Public Resources Code Section 13000 et seq.) for the provisions of water and sewer service in an unincorporated portion of the County of Napa. The District provides water and sewer service to the Berryessa Highlands and Oakridge Estates communities.
On August 19, 2020, the LNU Lightning Fire Complex burned through the community, destroying over 100 homes and damaging or destroying critical elements of infrastructure needed to operate the water and wastewater facilities, including the complete loss of Woodhaven Court Sewer Lift Station. On 1/10/2023 the Board approved $100,000 to be transferred from the District’s insurance settlement to the Woodhaven Court Sewer Lift Station Replacement Project (Project) for the preparation and completion of Project plans and specifications. Additional budget from the insurance settlement fund will be requested at the time of construction contract award to ensure construction costs are fully funded - including costs for construction inspection, project administration, and miscellaneous material acquisitions as needed.
The original sewer lift station was a 3,800 gallon steel tank with two - 5 horsepower pumps which served 15 parcels. The new precast concrete sewer lift station is proposed to hold 6,750 gallons of sewage and operate two - 3 horsepower pumps to serve the same 15 parcels. The system shall also incorporate a new control panel that has the ability to send system and sewage level alerts to operators through email and phone messaging, allowing the District to have a decreased reaction time to system failures. The lift station shall be installed at the same location as the previous lift station to connect to existing sewer force and gravity mainlines. Additional project components include privacy fencing, steel bollards for protection, and appurtenances to connect the new lift station to existing mainline piping.
The newly designed sewer lift station has increased capacity, lower horsepower pumps, and state of the art alarm system; with the plans and specifications now complete, the District Engineer requests approval to advertise the project for sealed bids and opening of the bids at a time, date, and location to be the District Engineer pursuant to Section 20150.8 of the Public Contract Code.
