HONDA PKG REHABILITATION PROJECTS

AT

CULEBRA NATIONAL WILDLIFE REFUGE

April 22, 2026

BACKGROUND:

The Culebra National Wildlife Refuge (NWR) RT#300 Admin Quarters Rd, RT#010ZZ HQ Entrance Rd and RT#901 Ensenada Honda Pkg require rehabilitation after sustaining surface damage from Hurricane Fiona in September 2022. Work will include material transportation to Culebra National Wildlife Refuge. Material will be stockpiled; the location has a limited capacity. Work will include the scarification, grading, shaping, slope and compacting of approximately 500 feet by 12 feet road, 950 feet by 15 feet road and a 380 square yards parking lot. These rehabilitations will include methods that reduce erosion and scouring, including but not limited to concrete gutters, riprap, planting, geocells, water crossing concrete pad where determined. In areas where scouring is visible perform regrading of the surrounding topography for water to cross on preexisting gutter or obvious low points on these roads. The purpose is to create more resilient roads that can better withstand storm related water damage. This Statement of Work (SOW) defines all the required tasks to repair the damages.

The material and performance specifications for the Construction Services tasks are incorporated in the project description below. Consult any changes or recommendations with the Contracting Office Representative (COR).

Any dimensions provided below are approximate in nature. The Contractor shall verify all dimensions and note such dimensions on the submitted proposal. Product data submittals shall be required for all construction materials and products proposed herein. Submittals will also be required for construction procedures for roads and parking.
