Hydaburg Harbor Development | Hydaburg, Alaska

Hydaburg Harbor Approach Trestle Under Construction | Hydaburg, Alaska


Project Overview

RPKA was retained by the Hydaburg Cooperative Association (HCA) to provide civil services for project development for replacement of the approach trestle and tidal grid adjacent to the boat harbor, as well as installation of a new boat launch for the Hydaburg Harbor Project. Our services included project scoping, cultural resources, wetland delineation, phase 1 site assessment, environmental documentation, permitting, control and topographic surveys, geotechnical investigation, utility relocation, and the plans, specifications and engineer’s estimate.


Environmental & Wetlands

For the environmental scoping, we prepared scoping materials as part of the NEPA process. The phase 1 site assessment investigation report identifies all known or potentially contaminated sites and clearly describes the location, type, and extent of contamination, and includes recommendations for any needed further investigation. The wetland delineation portion of the work identified sites that met determination criteria for hydrology, vegetation, and soils as wetlands. The cultural resources report was prepared by a qualified Archaeologist and determined the impacts to cultural resources near the project. RPKA produced the Categorical Exclusion environmental documents for this project as well.


Permitting & Design Services

RPKA prepared, submitted, and obtained permits for the project, such as a Coastal Zone Consistency Determination, COE Individual Permit, ADEC Certificate of Reasonable Assurance and ADEC Storm Water Pollution Prevention Construction Plan Review.

Our design services included production of the plans, specifications, and engineer’s estimates for the entire project.
