o Task 3: Cultural Resource Protections and Controls

The project will not cause a substantial adverse change in the significance of a historical resource per Section 106 of the National Historic Preservation Act (NHPA) of 1966 (as amended) described in 36 CFR 800.5(a)(1).

However, we make the following recommendations to ensure that cultural resources are not adversely affected by the proposed project. The project is not expected to have an adverse effect on cultural resources. The Contractor must adhere to the following stipulations:

a. Cultural Resource Awareness Training Prior to the initiation of the project a cultural resources training will be provided to supervisors, contract foreman, construction crew members, and any additional key construction personnel. The agency and or consulting archaeologist will administer the training. The purpose of the training is to increase awareness and knowledge of cultural resources and appropriate protocols in the event of an inadvertent discovery. The training will include a discussion of the unanticipated discovery protocol with an emphasis on the procedures for stopping work and notification of key personnel.

Appropriate protocols in the event that human remains are discovered will also be discussed. A training pamphlet Cultural Resources Guide to Identification and Protocols will distributed to all construction personnel. Upon completion of the training, participants will be able to define cultural resources, describe the policies and procedures for identifying and protecting cultural resources, know how to locate and receive assistance from the professional archaeologist and coordinate with other sources, and describe steps to be taken when cultural resources are encountered during project implementation. All new construction personnel added after construction commences will receive the same training and orientation before working on-site. In the event that Native American monitors are used, it will be necessary for tribal representatives to also participate in the training.

b. Unanticipated Discovery Protocol An Unanticipated Discovery Protocol will be developed for this project prior to the initiation of construction. The Unanticipated Discovery Protocol will describe the procedures to be followed if potential significant archaeological resources or human remains are encountered during project-related activities. The document will provide an outline of the unanticipated discovery protocol, potential reporting needs in the event of a discovery and the post-testing and monitoring reporting requirements, references and a list of contacts. The document will list key personnel and include specific contact information for those individuals. The Unanticipated Discovery Protocol will be available on-site during construction.

c. Unanticipated Discovery of Cultural Resources If previously unidentified cultural resources are encountered during project implementation, avoid altering the materials and their stratigraphic context. A qualified professional archaeologist should be contacted to evaluate the situation. Project personnel should not collect cultural resources. Prehistoric resources include, but are not limited to, chert or obsidian flakes, projectile points, mortars, pestles, and dark friable soil containing shell and bone dietary debris, heat-affected rock, or human burials. Historic resources include stone or abode foundations or walls; structures and remains with square nails; and refuse deposits or bottle dumps, often located in old wells or privies.

d. Encountering Native American Remains Although unlikely, if human remains are encountered, all work must stop in the immediate vicinity of the discovered remains, and an agency representative notified immediately. It should be noted that the “Most Likely Descendent” also known as the MLD process is state of California code and does not apply to human remains identified on federal lands. Per 43 CFR Section 10.4(b), inadvertent discoveries, NAGPRA notes that the responsible Federal agency official must be notified immediately via telephone with written confirmation. Additionally per subpart c, if the discovery occurred in connection with on-going activity on Federal lands, the activity must stop. Subpart d identifies the next steps as (i) certifying receipt of the notification; (ii) take steps to secure and protect the discovery; (iii) notify lineal descendants; (iv) initiate consultation;

(v) if excavation or removal is necessary follow Section 10.3(b), procurement of an ARPA permit; and (vi) ensure disposition of inadvertent discoveries follows Section 10.6.

e. Site Visition If deemed necessary and or to facilitate communication, the agency archaeologist may monitor construction either formally or informally. This may entail anything from being on-site during construction hours to occasionally checking-in with the contractor to ensure that everything is going smoothly and that nothing out of the ordinary has been encountered such as Native American and or historic-era artifacts, as well as paleontological finds.

Warranty Materials and equipment furnished under this Contract shall be covered by the most favorable commercial warranties given to customers for such materials or equipment. The rights or remedies provided herein are in addition to and do not limit rights afforded to the Government by other clauses of this Contract. With respect to warranties, expressed or implied, from manufacturers or suppliers for materials or equipment furnished under the Contract the Contractor shall:

Best Management Practices For the Protection of Water Quality

To maintain compliance with federal Clean Water Act Requirements, Contractor is responsible for adhering to Best Management Practices. The following list of Best Management Practices (BMPs) will be employed at treatment sites depending on the nature of treatments and the applicability of a given BMP for the site.

Construction and reconstruction BMPs:

1. Minimize fill volumes at stream crossings by restricting width and height of fill to amounts needed for safe travel and adequate cover for culverts. For deep fills (generally greater than 15 feet deep), incorporate additional design criteria (e.g., rock blankets, buttressing, bioengineering techniques) to reduce the susceptibility of fill failures.

2. Place sediment-trapping materials or structures such as straw bales, jute netting, or sediment basins at the base of newly constructed fill or side slopes where sediment could be transported to waters of the State. Keep materials away from culvert inlets or outlets.

3. Construct road fills to prevent fill failure using inorganic material, compaction, buttressing, sub-surface drainage, rock facing, or other effective means.

4. Locate waste disposal areas outside wetlands, Riparian Reserve, floodplains, and unstable areas to minimize risk of sediment delivery to waters of the State. Apply surface erosion control prior to the wet season. Prevent overloading areas, which may become unstable.

5. Design stream crossings to minimize diversion potential in the event that the crossing is blocked by debris during storm events. This protection could include hardening crossings, armoring fills, dipping grades, oversizing culverts, hardening inlets and outlets, constructing critical dips, and lowering the fill height.

6. Design stream crossings to prevent diversion of water from streams into downgrade road ditches or down road surfaces.

7. On new construction, install culverts at the natural stream grade, unless a lessor gradient is required for fish passage.

8. Place instream grade control structures above or below the crossing structure, if necessary, to prevent stream head cutting, culvert undermining and downstream sedimentation.

Employ bioengineering measures to protect the stability of the streambed and banks.

9. Prevent culvert plugging and failure in areas of active debris movement with measures such as beveled culvert inlets, flared inlets, wingwalls, over-sized culverts, trash racks, or slotted risers.

10. Utilize stream diversion and isolation techniques when installing stream crossings. Evaluate the physical characteristics of the site, volume of water flowing through the project area and the risk of erosion and sedimentation when selecting the proper techniques.

11. Disconnect road runoff to the stream channel by outsloping the road approach. If outsloping is not possible, use runoff control, erosion control and sediment containment measures.

These may include using additional cross drain culverts, ditch lining, and catchment basins.

Prevent or reduce ditch flow conveyance to the stream through cross drain placement above the stream crossing.

Surface Drainage BMPs:

1. Effectively drain the road surface by using crowning, insloping or outsloping, grade reversals (rolling dips), and waterbars or a combination of these methods. Avoid concentrated discharge onto fill slopes unless the fill slopes are stable and erosion-proofed.

2. Consider using broad-based drainage dips or leadoff ditches in lieu of cross drains for low volume roads. Locate these drainage features where they will not drain into wetlands, floodplains, and waters of the State.

3. Avoid use of outside road berms unless designed to protect road fills from runoff. If road berms are used, breach to accommodate drainage where fill slopes are stable.

4. Design roads crossing low-lying areas so that water does not pond on the upslope side of the road. Provide cross drains at short intervals to ensure free drainage.

5. Divert road and landing runoff water away from headwalls, slide areas, high landslide hazard locations, or steep erodible fill slopes.

Cross Drain BMPs:

1. Locate cross drains to prevent or minimize runoff and sediment conveyance to waters of the State. Implement sediment reduction techniques such as settling basins, brush filters, sediment fences, and check dams to prevent or minimize sediment conveyance. Locate cross drains to route ditch flow onto vegetated and undisturbed slopes.

2. Choose cross drain culvert diameter and type according to predicted ditch flow, debris and bedload passage expected from the ditch. Minimum diameter is 18.”

3. Locate surface water drainage features (e.g., cross drain culverts, rolling dips, and water bars) where water flow will be released on convex slopes or other stable and non-erosive areas that will absorb road drainage and prevent sediment flows from reaching wetlands, floodplains, and waters of the State. Where possible, locate surface water drainage structures above road segments with steeper downhill grade. Locate cross drains at least 50 feet from the nearest stream crossing and allow for a sufficient non-compacted soil and vegetative filter.

4. Armor surface drainage structures (e.g., broad based dips, and leadoff ditches) to maintain functionality in areas of erosive and low-strength soils.

5. Discharge cross drain culverts at ground level on non-erodible material. Install downspout structures or energy dissipaters at cross drain outlets or drivable dips where…
