The release of waters from theses (3) separate earthen embankment dam structures will require the Design/Build Contractor in Consultation with their Professional Engineers, Professional Dam Safety Engineers, and Consultants, to develop a strategy for controlled release of impoundment flows and upstream drainage flows because according to the Formal SEED Inspection Report for Crystal Springs Dam:

“If Crystal Springs Dam failed, the dam-failure flood wave would flow into Lower Crystal Dam.

From Lower Crystal Dam, the flood water would cross Stateline Road and continue into California. A hazard classification was performed and recommended that Crystal Springs Dam be classified as a Low Hazard Dam (Wheeler, 2019).”

Documents to be submitted to the Service for review and the Final Documents developed, prepared, and submitted to the Service.

In summary, the actual Final Documents for Permit Applications and Permit Support Documents to be based on the 100% Final Draft Construction Documents prepared.

As a result, a Comprehensive Project Description is required. The Project Description is to describe in detail the project work activities and durations.

The project description shall at a minimum include estimates on noise levels, the amount and type of vegetation removal, the amount of fill used, wetland impacts, the amount of sedimentation and turbidity from the Proposed Project, and impacts on Proposed Threatened and Endangered Species and Critical Habitat Areas.

The Project Description could be 30 to 50 pages in length and depending on the extent and size of the Project Improvements to be performed.

Note, a Comprehensive Detailed Project Description is provided as a separate attachment to this Statement of Work to demonstrate the level of effort expected in the preparation of the document.

The potential Task Breakdown is as follows:

Prepare and submit a Draft Detailed Project Description for USFWS Review.

Prepare and submit a Draft and Final Draft Wetland Survey and Ordinary High Water Mark

Delineation for USFWS Review (If Required).

The Wetland Survey and Ordinary High-Water delineation at a minimum should include the following:

5.B. TASK B. National Environmental Policy Act (NEPA) Documentation and Follow-up NEPA Review.

(OPTION TASK) – Qualified Estimate.

Develop, prepare, and submit necessary NEPA Documentation using the Detailed Project Description. The NEPA Documentation could consist of a Formalized Environmental Assessment (EA) if that is the Agency’s Level of NEPA Review determination.

After the NEPA Documentation is developed, prepared, and submitted, the Design/Build Contractor and their Permitting Consultant(s) shall perform the three levels of NEPA review to include Categorical Exclusion (CATEX), Environmental Assessment (EA), and Environmental Impact Statement (EIS). For the purposes of this Design/Build Contract and to ensure a thorough analysis of the Project, Project Improvements, and Effects of implementing Project Actions, the USFWS will not pre-determine what the required Level of NEPA Review would be because the Project Improvements require further definition before an actual Level of NEPA Review determination is established by the Agency.

However, for the purposes of estimating and establishing the Design/Build Contractor’s Proposal, the Design/Build Contractor shall assume an Environmental Assessment (EA) would be required for the Project Work Activities to be performed.

For the NEPA Documentation and Review, the Design/Build Contractor and their Permitting Consultants will identify public scoping items and conduct public meetings during times of the day that the public is available and include translators where necessary. The selection of appropriate times is to allow the public to attend the meetings. The Design/Build Contractor and their Permitting Consultants will synthesize topics to be included or dismissed for consideration in the EA Documentation.
