1.7 ANTITERRORISM (AT) - OPERATION SECURITY (OPSEC)

a. General Security Requirements and Guidance: The security requirements described below apply to all contract personnel (including employees of the prime Contractor ("Contractor") and all subcontractor employees) supporting the performance requirements of this contract.

The Contractor is responsible for compliance with these security requirements. Questions regarding security matters must be addressed to the designated Government representative (e.g., Contracting Officer Representative (COR), Requiring Activity (RA) representative, or Contracting Officer (if a COR or other RA representative is not appointed)). Contract personnel are critical to the overall security and safety of US Army Corps of Engineers (USACE) installations, facilities and activities, and security awareness training contributes to those efforts. The Department of Defense (DoD) and Army security training requirements specified below, if applicable, are performance requirements; all applicable contract personnel must complete initial training within 30 days of contract award or the date new contract personnel begin performance on the contract. Within five business days from the completion of training, the Contractor must provide written documentation (e.g., email or memorandum) to the Government representative. The documentation must include the names of contract personnel trained and which training they completed; the Contractor must maintain training records as part of their contract files and be prepared to provide copies of training certificates to the Government representative. Contractor personnel and vehicles are subject to search when entering federal installations. Additionally, all contract personnel must comply with Force Protection Condition (FPCON) measures, Random Antiterrorism Measures (commonly referred to as "RAMs"), and Health Protection Condition (HPCON) measures. The Contractor is responsible for meeting performance requirements during elevated FPCON and/or HPCON levels in accordance with applicable RA plans and procedures --this includes identifying mission essential and non-mission essential personnel. In addition to the changes otherwise authorized by the changes clause of this contract, should the FPCON or HPCON levels at any individual facility or installation change, the Government may implement security changes that affect contract personnel. The Contractor must ensure all contract personnel are aware of their security responsibilities, including any site-specific requirements identified in local policies or procedures.

b. Antiterrorism (AT) Level I Training: All contract personnel requiring

SECTION 01 00 00 Page 6 routine access to Army installations, facilities, and controlled access areas, or requiring network access must complete initial and annual refresher AT Level I awareness training. Online AT Level I awareness training is available at https://jko.jten.mil/ (website subject to change).

c. Physical Security and Access Control Requirements: All contract personnel requiring physical access to a federal installation or facility must comply with the access control procedures of that location. Contract personnel requiring unescorted access to meet contract performance requirements on a DoD installation in the US must be vetted by the installation/facility Provost Marshal/Directorate of Emergency Services/Security Office using the National Crime Information Center-Interstate Identification Index (commonly referred to as "NCIC-III") and Terrorist Screening Database (commonly referred to as "TSDB"). Contract personnel must comply with all personal identity verification requirements specified in installation/facility policies and procedures. Contract personnel who do not meet requirements for unescorted access to USACE facilities must coordinate escorted access with the Government representative, as needed.

Contract personnel who receive keys, access cards, or lock combinations that provide access to government-owned property must comply with key and lock control procedures of the RA.

d. Suspicious Activity Reporting Training (e.g. iWATCH, CorpsWatch, or See Something, Say Something): All contract personnel must receive initial and annual refresher training from the RA representative on the local suspicious activity reporting program. This locally developed training provides contract personnel with general information on suspicious behavior, and guidance on reporting suspicious activity to the project manager, security representative or law enforcement entity.

e. Pre-screen Candidates using E-Verify Program: Contractors must comply with the requirements set forth in FAR clause 52.222-54 Employment Eligibility Verification and FAR Subpart 22.18 in using the E-Verify Program at ( https://www.e-verify.gov/ ) (website subject to change) to meet the contract employment eligibility requirements. Contractors are encouraged to cooperate with Federal and State agencies responsible for enforcing labor requirements to include eligibility for employment under United States immigration laws in accordance with FAR 22.102-1(i). An initial list of verified/eligible candidates must be provided to the COR no later than three business days after the initial contract award. When contracts are with individuals, the individuals will be required to complete a Form I-9, Employment Eligibility Verification, and submit it to the Contracting Officer to become part of the official contract file.

1.8 UTILITIES

1.3 WORK COVERED BY CONTRACT DOCUMENTS

1.3.1 Project Description

The work includes stream bank protection and stabilization of the existing Lower American River (LAR) levee system to protect critical infrastructure against the effects of erosion during large flood events. Refer to Drawings for project location and limits.

The work involves, but is not limited to: clearing, grubbing, and stripping within the construction limits and areas designated in the Drawings and by the Contracting Officer; protecting-in-place vegetation, existing facilities, and structures not scheduled for removal; earthwork, including import of earthen and rock materials, construction of stone protection structures shown on the Drawings, construction of a temporary haul route beneath the Watt Avenue bridge on the north bank of the LAR, construction of temporary and permanent bicycle and pedestrian pathway and public access improvements, installation of planting benches, instream wood structures and live cuttings; grass seeding and erosion control;

maintenance of seeding to meet performance requirements through the Establishment Period as defined in these Specifications; replacement of existing infrastructure disturbed or relocated by construction, and all incidental related work.

SECTION 01 11 00 Page 3

1.3.2 Location

The work is located on the LAR within the American River Parkway in Sacramento, California and consists of specific sections of riverbank on both the north and south banks. The exact Site locations are shown on the Drawings.

1.3.2.1 C3B-North

Includes two project sites: Site 3-1 is located along the north bank of the LAR from the Howe Avenue Bridge at River Mile (RM) 7.7 extending upstream to RM 8.8, approximately as indicated; and Site 4-2 is also on the north bank of LAR from RM 9.8 upstream to RM 10.3, approximately as indicated.

1.3.2.2 C3B-South

Includes one project site: Site 4-1 is located along the south bank of the LAR from the Watt Avenue Bridge at RM 9.1 extending upstream to RM 10.5, approximately as indicated.

1.3.3 Phasing of Work (C3B - North and South)

The year listed in this section are defined as the construction year for the Erosion Protection Contract with Year 1 anticipated to be the year of the Contract Award.

Haul route traffic is defined as the routing of haul trucks, loaded or unloaded, through points of ingress/egress on the site. For the purposes of this Section, haul trucks are trucks that are used to carry material from outside the work limits to inside the work limits. Refer to Section 01 50 00 TEMPORARY CONSTRUCTION FACILITIES AND CONTROLS for definition of haul trucks and the Haul Route Ingress/Egress and Direction Traffic Flow map attached at the end of this section.

See table below for ingress/egress locations referenced in Paragraph Restrictions under Paragraph Phase 2 - Erosion Protection (Year 1) and in Paragraph Restrictions under Paragraph Phase 3 - Erosion Protection (Year 2):

Mayhew Drain N/A* C3B South, GC104

SECTION 01 11 00 Page 4

Ingress/Egress Name Nearby Stationing Sheet ID

*Intersection of haul route along Mayhew Drain at Folsom Blvd does not have stationing nearby but is shown in plan view H1 on GC104 with the text "Stablized Vehicle Entrance" near points WL 390 and WL 392.

No other haul route traffic points of ingress/egress can be used or created unless approved by the Contracting Officer. Additionally, haul route traffic direction is restricted by year to minimize damage to the buried cut-off-wall beneath the levee crown. No other haul route traffic points of ingress/egress can be used or created unless approved by the Contrcting Officer. Loaded trucks could create more damage than unloaded trucks generally, but the cut-off-wall’s strength varies beneath the levee crown, making optimization difficult. These restrictions were developed with the assumption that haul route traffic is minimized over particularly vulnerable areas of the cut-off-wall.

If the Contractor recognizes that changes to the restrictions listed below could minimize loaded trucks on the levee crown, discuss with the Contracting Officer. Restrictions may be able to be adjusted to accommodate theoretical haul route plans.

Small personal vehicles and trailers carrying equipment are not required to follow these haul route traffic restrictions in paragraph PHASE 2 - EROSION PROTECTION (YEAR 1) and paragraph PHASE 3 - EROSION PROTECTION

(YEAR 2).

1.3.3.1 Phase 1 - Tree Clearing and Transplant

Work to be completed under a separate service contract. Clearing work for the first construction season will occur between September 1 of Year 0 and February 1 of Year 1. Clearing work for the second construction season will occur between September 1 Year 1 and February 1 Year 2. Elderberry transplanting will occur between November 1 Year 0 and February 15 Year 1.

1.3.3.2 Phase 2 - Erosion Protection (Year 1)

Commence work after the regulatory flood season restriction of November 1 Year 0 to April 15 Year 1. Work on levee embankment rock slope protection for Sites 3-1 and 4-2 may commence before in-water work is permitted in Year 1. The in-water work window is between July 1 and October 31.

Additionally, it is anticipated that the downstream portion of Site 3-1 (Segment 3-9), Site 4-2, and the downstream portion of Site 4-1 (Segments 3-5 and 3-6) will be completed in Year 1.

1.3.3.2.1 Restrictions

Haul route ingress/egress points and direction provided for Year 1 cannot be changed due to risk reduction measures for the buried cut-off wall. See Attachment 1 - Haul Route Ingress/Egress and Direction Traffic Flow.

a. Haul route traffic for construction of C3B-North, Site 3-1, downstream of Watt Avenue Bridge, must pass from the ingress point of University Park to the egress point of Kadema.

b. Haul route traffic for construction of C3B-North, Site 4-2, upstream of Watt Avenue Bridge, must pass from the ingress point of Wilhaggin

SECTION 01 11 00 Page 5 to the egress point of Harrington Way.

c. Haul route traffic for C3-B North may not cross under Watt Avenue Bridge.

d. Haul route traffic for construction of C3B-South, Site 4-1, must pass from the ingress point of Watt Avenue to the egress point at Mayhew Drain.

1.3.3.3 Phase 3 - Erosion Protection (Year 2)

This phase will continue the erosion protection improvements for the upstream portions of Site 3-1, C3B-North haul route operations and site improvements under Watt Avenue, and Site 4-1 which will be completed in construction Year 2. Work is also subject to the regulatory flood season restriction.

1.3.3.3.1 Restrictions

Haul route ingress/egress points and direction provided for Year 2 cannot be changed due to risk reduction measures for the buried cut-off wall. See Attachment 1 - Haul Route Ingress/Egress and Direction Traffic Flow.
