Aquatic Resource Mitigation Fund

Working to sustain the functions and values of aquatic resources in New Hampshire.

When there are unavoidable impacts to streams and wetlands, the Aquatic Resource Mitigation (ARM) Fund offers an alternative to permittee-responsible mitigation. An In-Lieu Fee (ILF) payment may be made to the ARM Fund to compensate for losses to aquatic resources and functions from a project. The funds are pooled according to nine watersheds called Service Areas, and then made available as competitive grants to fund preservation, restoration and enhancement activities across the state. As the ILF sponsor, NHDES holds and manages the collected funds, and announces a grant round (i.e. Request for Proposals) annually. The goal of the program is to support conservation activities that are ecologically important and will effectively sustain aquatic resource functions in the watershed for the long term.

Grant applications are reviewed by the site selection committee that uses a set of evaluation criteria, along with the best available science provided by the Wildlife Action Plan, Natural Heritage Bureau, regional conservation plans, and functional assessments done by experts in the field of wetlands science.

Funds can be used to protect, restore and enhance wetlands and streams. The program seeks to fund projects that will maintain and increase important functions such as water quality, wildlife habitat and flood storage.

Service areas are designated by the boundaries of nine major river basins. The impact payments that go into the ARM Fund can only be used to fund projects within the same service area.

In 2021 there were 12.3 acres of wetland loss, 5,000 feet of bank and channel stream impacts, and 0.5 acres of wetland conversion that required compensatory mitigation and generated the available funds. Please view the 2022 ARM Fund Ledger to understand the resource types and functions and values lost in each the watershed.

Site Selection Committee

the site selection committee surveys a wetland








The Site Selection Committee is a team of state and non-governmental conservation agencies that review the applications and recommend funding for projects. Team members represent a breadth of expert knowledge in the fields of botany, wetlands ecology, wildlife biology, and stream science, and have decades of experience working in New Hampshire on environmental issues. The committee reviews the applications using the best available science and visits the sites to rank projects using the evaluation criteria.

Funding Conservation Across New Hampshire

Since 2009, the ARM Fund has provided funding for 124 projects across the state, protecting over 25,000 acres.

Tracking Impacts

The mitigation program tracks the resources and functions lost from the permitted impacts that generate the ARM funds, key to finding projects that will adequately offset the losses in the watershed.
