Saltery Point Road | Hydaburg, Alaska

Hydaburg Saltery Point Road Bridge

Saltery Point Road Bridge Under Construction | Hydaburg, Alaska


RPKA provided the Hydaburg Cooperative Association with survey, design, environmental scoping, and cultural resources pre-construction services for the Saltery Point Road Project. Saltery Point Road is a vital economic access road that leads to the deepwater port at Saltery Point. The project entailed reconstruction of the roadway in order to eliminate the one lane sections, straighten some of the corners, and replace the bridge.


Environmental Scoping

To complete environmental scoping work we prepared scoping materials as part of the NEPA process. We prepared all materials necessary to present the proposed project to federal, state, and local agencies and organizations, as well as the public and businesses for comment. Materials provided include a scoping mailing list, scoping letter with attached project location map and vicinity map, and information about the project for BIA to conduct IFF activities. Services also include a meeting with the HCA, the City of Hydaburg, and the public during one site visit to the community.


Cultural Resources

RPKA is responsible for conducting a cultural resource survey of the proposed project. A qualified Archaeologist prepare the archaeological report. Cultural resources reports are prepared in accordance with Department of Interior standards to determine if any impacts to cultural resources are likely to be near the project. The work consists of literature research, field survey, and preparation of a cultural resources report.


Wetland Delineation

RPKA conducted a wetland delineation in accordance with the 1987 USACE Wetland Delineation Manual and the 2006 Alaska District Supplements. We are investigating the entire project corridor will be investigated and sites that meet determination criteria for Hydrology, Vegetation and Soils will be documented as wetlands. The wetland delineation documentation produced is sufficient for ACOE to make a jurisdictional determination and for later use in permitting to determine the acreage of wetlands impacted by the project once designed and the amount of fill needed.


Site Investigation

RPKA performed a site investigation and assessment in accordance with the procedures detailed in the American Society for Testing and Materials’ publication ASTM 1527-05. All known or potentially contaminated sites identified during the investigation were clearly described including the location, type, and extent of contamination, if known. The report includes recommendations for further investigation, if appropriate. Applicable background information such as logs of personal interviews, aerial photos, land use records, previous reports, and pertinent information from regulatory agency files were appended to the report.


Due to the wetland impacts of this project RPKA also produced an Environmental Assessment (EA), which is issues-based, evaluates potential impacts and provides a basis for determining whether the potential impacts of the proposed project would be controversial or significant for this project. The EA presents probable beneficial and adverse social, economic, and environmental impacts of each alternative where significance is uncertain. In addition, RPKA was also responsible for preparing, submitting, and obtaining permits in HCA’s name for this project.


Design & Construction Services

For survey services, RPKA furnished all survey equipment, field books, stakes, lath, and other devices necessary for establishing lines, as well as collecting and recording data. We measured and record the location, topographic, and hydraulic data in accordance with standard engineering and surveying practices. The survey consisted of all work necessary to complete the project. All field measurements recorded electronically were kept in field notebooks in sufficient detail for interpretation and verification. Upon completion of the work, a copy of the signed and stamped field notebooks was submitted to the client. The survey was tied into previous survey work completed for the Community Streets project, providing a complete combined survey of the project area.


Geotechnical Investigation

RPKA conducted a geotechnical investigation to determine the soil and groundwater conditions and present our opinions, conclusions and recommendations for the proposed roadway embankment, bridge foundation design, and pavement design. The potential material source for the project was also be investigated to determine its adequacy. Soil samples were collected at each change in soil type, as well as change in materials from the test pit. We also conducted pentrometer tests next to each test pit to determine in-situ strengths. The samples were transported back to our office for analysis and testing. All material testing is completed in RPKA’s in-house laboratory and completed in accordance to ASTM standards and includes moisture content, grain-size distribution tests and moisture-density relationship.


Utility Relocation Assessment

Based on existing as-built data and our survey efforts, RPKA determined above and below ground utilities needing relocation as part of the project.


Project Deliverables

RPKA provided complete sets of plans, specifications, and estimates in accordance with AASHTO guidelines. As part of these services RPKA calculated the Construction Pay Item Quantities and estimated Pay Item Construction Costs for the project. Then RPKA provided documentation of detailed calculations and references used in preparing the Engineer’s Estimate. RPKA developed an Engineer’s Estimate of construction costs based on the estimated quantities and unit prices prevailing in the project area.


Right-of-Way Aquisition

RPKA’s responsibilities included acquiring the required Right-Of-Way (ROW) for the project through the use of easements rather than platting. As part of this work, we conducted a title search of the impacted properties using a title company. Documents were then prepared, using RPKA’s standard easement documentation, which includes a legal description of the property impacted, as well is a drawing showing the impacts.
