About this file
This Statement of Work details a marsh restoration project for the Edwin B. Forsythe National Wildlife Refuge located on Cedar Bonnet Island in Ocean County, New Jersey. The U.S. Fish and Wildlife Service seeks a contractor to move a minimum of 600 cubic yards of compost material onto a marsh platform using airboats, with the goal of restoring high marsh habitat by creating mounded, well-drained features. The Ocean County Utilities Authority will provide compost made from community yard clippings, which will be delivered to a staging site approximately 500 feet from the marsh access point.
The project involves precise placement of compost using RTK GPS surveys, with refuge staff delineating and staking placement areas, providing on-site oversight, and conducting final hand grading. After compost placement, staff will install erosion control fabric and plant salt marsh grass plugs. The adaptive management plan includes adding 8" of compost to previously designed high marsh zones, creating a dead-end channel block to promote sediment retention, and establishing small isolated ponds to help drain high marsh areas and provide fish habitat for mosquito control. The contractor will be responsible for loading, transporting, and unloading the compost while minimizing damage to the marsh ecosystem.

STATEMENT OF WORK
COMPOST MARSH PROJECT
Station: Edwin B. Forsythe National Wildlife Refuge, U.S Fish and Wildlife Service
Location: Cedar Bonnet Island, Stafford Township, Ocean County, New Jersey (Figure 1)
Background: Cedar Bonnet Island is the site of a marsh restoration project on Edwin B. Forsythe National Wildlife Refuge where adaptive management is needed to restore high marsh habitat. The area is a former dredge disposal site that was graded down to marsh elevations and restored to salt marsh 10 years ago. Since then, all restoration goals have been met except that areas graded to high marsh elevations have not fully revegetated. With previous projects we have demonstrated that the addition of compost as a topsoil in this setting will provide a suitable substrate for planted vegetation to thrive. We have a partner in Ocean County Utilities Authority, who can deliver compost that they create using yard clippings from the community to the site.

Project Goal: The goal of the project is to restore high marsh habitat by using organic compost as a peat substitute to create mounded well-drained features.
Project Components:
• The USFWS is seeking a contractor to move a minimum of 600 cubic yards of compost material from a staging area onto the marsh platform using airboats to ensure minimal damage to the marsh.
• Project design will be conducted by Forsythe NWR staff using RTK GPS surveys to determine material placement extent and depth.
• Refuge staff will delineate and stake placement areas to guide field operations and will be onsite to provide oversight to the contractor and conduct final grading (by hand) after compost placement.
• Refuge staff will install erosion control fabric where needed and carry out planting of salt marsh grass plugs after placement.
• The Ocean County Utilities Authority (OCUA) will provide and deliver compost to a staging site approximately 500 feet from where airboats can access the marsh. See Figure 2.
• The contractor will be responsible for loading compost onto equipment that will transport it to the airboats, and then to unload the material from airboats onto the marsh at designated locations to be marked by refuge staff.
• The contractor will coordinate with refuge staff and OCUA on appropriate staging sites and delivery logistics.
• The contractor will work with staff during all operations to ensure damage to the marsh is limited.
• General placement areas are indicated in Figure 3.
