Watersheds United Vermont 

Watersheds United Vermont (WUV) is a state-wide network of local groups dedicated to the health of their home watersheds.

WUV's mission is to empower community-based watershed groups in all parts of the state to protect and restore Vermont’s waters.

Watershed Groups are broadly defined as a community-based organization working with individuals and communities in their local watersheds to protect and improve water quality, habitat, and flood resilience and to build social and ecological connections with Vermont’s waters. Watershed organizations work with all watershed constituents and do not represent a specific constituency or interest group. 

Enhancement Project Development Grant (EPDG)

Overview

Watersheds United Vermont (WUV) is administering funding under the Enhancement Project Development Grant (EPDG) program, which will support the project development of priority water quality enhancement projects from July 2026 through June 2028. WUV seeks proposals for the development of new enhancement projects and for the development efforts needed between the design and implementation phases of enhancement projects.

The EPDG program is part of WUV’s larger Enhancement Development, Design and Implementation Block Grant (EDDIBG) through the Vermont Department of Environmental Conservation’s (VT DEC) Clean Water Initiative Program (CWIP). WUV has separated out the Project Development portion of this grant as the work completed under project development is significantly different from the work completed under design and implementation.

No match is required under this program. Please note that this funding can be used as match/leverage for other funding sources.

Oregon Sea Grant

Established at Oregon State University in 1971 as one of the first four Sea Grant College Programs designated in the nation, Oregon Sea Grant is now one of 34 programs within the National Oceanic and Atmospheric Administration's Sea Grant College Program. Congress established the national Sea Grant program in1966. Oregon Sea Grant is cooperative program between NOAA and Oregon State University. Our programs serve all of Oregon. Our core-funding is from NOAA Sea Grant and requires a 50% match of non-federal funding. Oregon State University is our primary non-federal fiscal partner, but we rely on many other collaborators and partners, including local governments, agencies, industry, and philanthropy to expand our capacity to address ongoing, unexpected, and emerging needs of Oregon's coastal communities and ecosystems.

We address regionally and nationally strategic issues through an integrated program of competitive, rigorously reviewed research, extension services and projects, and public education. We support dynamic, inventive, and flexible approaches to meet the needs of communities in changing natural and social environments.

Program Development Grants

Oregon Sea Grant offers modest grants for project opportunities or special circumstances when resources are available.

These funds generally are not intended to supplement an existing project, but to provide seed money for exploratory or high-risk efforts, or to respond to urgent needs or unforeseen opportunities that require a timely effort.

Purpose

In addition to competitive grants awarded on a two-year cycle, Oregon Sea Grant offers modest grants for project opportunities or special circumstances, when resources are available. These projects typically arise between the regular application periods and must align with the Oregon Sea Grant strategic plan. These funds generally are not intended to supplement an existingproject, but to provide seed money for exploratory or high-risk/impact efforts, or to respond to urgent needs or unforeseen opportunities that require a timely effort. Oregon Sea Grant also considers requests for event support (or total requests less than $2,500) through our Conference and Activity Support program (see the Oregon Sea Grant “Conference and Activity Support Policy” for details).

Funding

Development grants are modest in size (total awards typically do not exceed $10,000) and should be one year or less in duration. Larger requests are occasionally considered, and are subject to peer review and approval by the National Sea Grant Office. Given our limited funding, success of requests in excess of $10,000 (total award) will be lower. While cost share is not required for program development proposals, opportunities for leveraged funds are welcome. Please contact us to discuss possible cost share for your project.
