Performance Work Statement Lake Berryessa East Side Road Seeding

1.0 Purpose

The purpose of this Performance Work Statement (PWS) is to define required performance outcomes for restoration seeding across fire‑impacted lands along East Side Road at Lake Berryessa. The Lake Berryessa Field Office has successfully applied for BIL-BAR 5-10 Year Post Fire Recovery Funding in FY 25 and would like to use this funding to re-seed the area and implementing recommendations from a July 2008 Lake Berryessa East Side Grazing Management Plan.

2.0 Background

The Bureau of Reclamation created the reservoir of Lake Berryessa in the 1950’s as part of the Solano Project, authorized by the Reclamation Project Act of 1939 (53 Stat. 1187). Solano Irrigation District operates the Solano Project under an agreement with Reclamation, although the reservoir and surrounding land are federal lands managed by Reclamation. At capacity, Lake Berryessa stores 1.6 million acre-feet (af) of water and is one of the largest bodies of fresh water in California. The lake is 23 miles long by 3 miles wide and has 165 miles of shoreline.

In August of 2020, a series of spot fires ignited and converged to form the LNU Lightning Complex Fire, which burned the northern-most 400 acres of the former Lake Berryessa Wildlife Area as well as 60% of the Solano Project Lands around Lake Berryessa. The recovery resulted in several time-consuming employee and public safety projects. This workload, when combined with a sharp decline in field office staff post-pandemic and post-fire, meant that a project to address the rise in invasive plants, including black mustard, along the eastern shore of Lake Berryessa could not be addressed until now.

3.0 Scope of Work

The Contractor shall provide all labor, supervision, native seed, equipment, tools, and materials needed to conduct no‑till seeding of approximately 383.8 acres across five paddocks. The Contractor is responsible for achieving the performance outcomes defined in this PWS.

Prior to the start of work the contractor must submit and receive approval of a detailed Work Plan and Quality Control Plan.

Acreage by paddock:

4.0 Performance Requirements

4.1 Seed Mix Procurement

The Contractor shall:

Provide a 100% native grass and wildflower seed mix.

Include no fewer than five (5) species from the Government‑provided species list.

Ensure seed purity, viability, and labeling in accordance with state and federal law.

Provide seed documentation with the work plan and again prior to application.

Approved Species List:

Existing Vegetation Monitoring Summary:

The tenth year of annual monitoring was conducted on April 9, 2024, utilizing three linear monitoring transects established in 2015. Transect M-1 measures 90 meters in length while M-2 and M-3 each measure 50 meters in length. The three transects include a total of 35 monitoring plots, each measuring 1x1 meter square and positioned 5 meters apart (= 0.014% of 60 acres). Cover is visually estimated and assigned to a cover class: A, < 2%; B, 2-10%; C, 10-25%; D, 25-50%; and E, > 50%. Total cover is estimated to a precise percent in each plot. Cover of individual species is also estimated to absolute percent cover to permit determination of Relative Native Cover. (No fractional cover values are applied; the minimum value assigned is 1%).

Desired Monitoring:

Vendor will establish linear transects in each of the 5 parcels. Each transect will be 2-meters in width and 50 meters in length starting from the permanent fenceline adjacent to East Side Road and extending towards the shoreline. The transects will be laid out using a measuring tape before seeding, after seeding, and 6 months after seeding using the same fixed endpoints such as a fence, shrub, or stake. Utilizing the centerline of the tape as the axis of the transect, plants rooted up to one meter away from the measuring tape will tabulated.

4.2 Seeding Application

The Contractor shall:

· Apply seed using a no‑till drill.

· Seed the entirety of the designated paddocks, achieving total treated acreage within 3% of the Government‑identified acreage.

· Ensure even seed distribution consistent with native grassland restoration standards, and industry best practices.

· Conduct seeding only during the months of October - November unless otherwise approved in writing by the Government.

· Comply with all environmental and biological protection measures contained in Section 7.0.

5.0 Work Plan Requirement

Before beginning work, the Contractor shall submit a Work Plan to the Government for approval.

The plan shall include:

· The final seed mix (species and quantities).

· Equipment to be used (including decontamination procedures).

· The contractor’s planned seeding approach and sequencing.

· Estimated daily production rates.

· Environmental compliance methods.

No work may begin until the Government issues written approval of the work plan.

5.1 Re‑Performance Requirement

If the Contractor varies from the approved work plan without written Government authorization, the Contractor shall, at no additional cost to the Government:

· Re‑perform any portion of the work that does not meet PWS performance outcomes;

· Replace or reapply seed in areas where improper application occurred;

· Remedy non‑conforming work as directed by the Government.

The Government reserves the right to reject any work not performed in accordance with the approved plan or this PWS.

6.0 Quality Control Plan (QCP)

Within 15 days after award, the Contractor shall submit a Contractor Quality Control Plan that describes inspection procedures, personnel roles, monitoring frequency, and corrective action processes. The plan must be approved by the Contracting Officer prior to commencing work.

7.0 Environmental Protection Requirements

7.1 Worker Environmental Awareness Training (WEAT)

Worker Environmental Awareness Training: Prior to the commencement of Project work, all Project personnel will attend an environmental awareness training. It will include; species descriptions and habitat needs, species status and protection under the Endangered Species Act, definition of take, reporting requirements, conservation measures to reduce project impacts, and instructions for encountering California Red-legged Frog (CRLF) and Keck’s checker-mallow in areas where take could occur. Employees will sign a form stating that they received and understand the training. Reclamation will maintain a list of personnel receiving the training.

7.2 Pre‑Construction Biological Surveys

Prior to any ground disturbing activities, pre-construction biological surveys will be conducted in the action area for CRLF and Keck’s checker-mallow. Surveys will be conducted by a qualified biologist within 14 days prior to commencement of the work.

7.3 Wildlife Protection During Work

To reduce the potential for Project vehicles striking CRLF, a 10-mile-per-hour speed limit will be enforced at the site.

No work will occur during or 24-hours following a rain event. A rain event is to be considered precipitation of ¼-inch or more within a 24-hour period.

All Project personnel will be informed of the Action Area boundaries for Project activities. If necessary, flagging and/or staking may be used to define the Project area limits.

7.4 Vehicle and Equipment Decontamination

To prevent spread of invasive species, disease, or contaminants:

All equipment and vehicles shall be fully decontaminated prior to arriving on site.

Decontamination steps must be described in the Work Plan.

7.5 Ground Preparation

The Government will perform required ground preparation (e.g., controlled burns). The Contractor shall coordinate timing and shall not enter the site until the Government confirms it is safe and ready.

8.0 Government-Furnished Property / Access

The Government will provide access keys for gates along East Side Road and the Eticuera Day Use Area.

All other equipment, seed, and supplies shall be provided by the Contractor.

9.0 Period of Performance

Base Year: 10/01/2026 – 11/30/2026 Option Year 1: 10/01/2027 – 11/30/2027 Workdays: Monday–Friday, excluding federal holidays.

9.1 Paddock Option Year

Native grassland establishment can be impacted by environmental conditions, soil moisture, post‑fire succession, precipitation timing, and other natural factors outside the Contractor’s control.

Based on Government monitoring following the base‑year seeding, some paddocks may require additional reseeding the following year, while others may not.

To accommodate this, the Government intends to include separate option‑year CLINs for each paddock. The Government will exercise only the CLINs associated with those paddocks that the Government determines require reseeding.

If an option‑year CLIN is exercised, the Contractor shall perform reseeding in accordance with the requirements of this PWS and the approved Work Plan for that performance period.
