Stormwater MS4 Municipal Assistance Grant Program
This program, introduced in 2017, enables groups of Massachusetts municipalities to expand their efforts to meet requirements for the 2016 Small Municipal Separate Storm Sewer System (MS4) General Permits, and to reduce stormwater pollution through coordinated partnerships that emphasize resource sharing.
Total Funding Available:
Estimated Grant Amounts:
Since 2012, officials of Massachusetts cities and towns have come together and formed regional stormwater coalitions to share resources, training, and best management practices related to stormwater management. Those regional coalitions also formed a statewide coalition to meet those same goals. In April 2016, the United States Environmental Protection Agency (EPA) and MassDEP issued a renewal of the Small MS4 General Permit (2016 MS4 Permit) for Massachusetts, which became effective on July 1, 2018. On November 22, 2024, the EPA prepared a renewal of the 2016 MS4 Permit for public comment which carries forward and builds upon previous MS4 Permits. The public comment period ran from November 22, 2024 through May 21, 2025. Finalization of the permit is ongoing and will not be completed prior to the issuance of this RFR. Since the 2016 MS4 Permit is administratively continued until the USEPA issues the renewal permit, projects to meet the 2016 MS4 Permit requirements will be prioritized.
MassDEP seeks to help facilitate municipal and regional collaboration on improved stormwater management and permit compliance through the MS4 Municipal Assistance Grant Program.
Washington State Department of Agriculture
WSDA has been serving agriculture and the public for more than 100 years. Through service, regulation, and advocacy, we support keeping agriculture viable and vital in Washington State, while protecting consumers, public health, and the environment.
Farm to School Purchasing Grants
Washington State Department of Agriculture’s (WSDA) Farm to School Program exists to facilitate increased use of Washington grown food by schools.
The purpose of the Farm to School Purchasing grants is to increase the purchase, use, and promotion of foods that are grown, raised, caught, or foraged in Washington by child nutrition programs with an emphasis on procurement from small and direct marketing farms and food businesses, including but not limited to, socially disadvantaged, beginning, limited resource, women and veteran farmers and ranchers.
Grant funds are intended to support schools and early learning services in sourcing and preparing high quality, nutritious, culturally relevant foods for their meal programs.WSDA Farm to School Purchasing Grants are reimbursement grants. Grants are awarded based on a competitive application and review process.
There are two application types: School Meals and Childcare Meals
Eligible applicants may apply for one or more application type.
*New for the 2025-2027 Biennium*
There is no option to apply for a purchasing grant solely for Summer Meal programs. School Meals applicants who operate SFSP or SSO may include summer meals as part of their School Meals application. Award amounts are detailed in the Maximum Eligible Awards section of the grant guidelines.
Eligible Expenses
Farm to School Purchasing Grant funds must be used to support the grant purpose of increasing use of Washington grown, raised, caught, or foraged foods.
Farm to school purchasing may:
The Farm to School Purchasing Grant may be used to cover non-food costs in addition to direct food purchases. Non-food costs must directly support the project plan’s efforts to purchase and promote foods grown, raised, or caught in Washington State.
Awardees may use up to 25% of their total awarded grant funds on eligible non-food costs. Awardees must spend at least 75% of the awarded grant funds on food purchases.
See the list below for examples of eligible expenses. These lists are not exhaustive, there may be eligible expenses not included in the list of examples.
Indirect costs are not permitted as part of the project budget for this program. Administrative costs, such as fiscal office staff time, are permitted as a non-food cost in lieu of indirect costs.
Examples of Eligible Food Costs
Grantees may purchase foods grown, raised, harvested, and packaged or processed in Washington from various sources including, but not limited to:
The following products are examples of foods that are eligible for reimbursement with the Farm to School Purchasing Grant:

MassDOT Complete Streets Funding Program
The MassDOT Complete Streets Funding Program provides Massachusetts municipalities with tools and financial support to address gaps in their local transportation networks. A “Complete Street” is one that provides safe and accessible options for all travel modes—including walking, biking, transit, and vehicles—for people of all ages and abilities.
When launched in 2016, the program utilized a three-tiered system to incentivize long-term change through the adoption of local Complete Streets Policies (Tier 1), Prioritization Plans (Tier 2), and construction grants (Tier 3). After ten years of successful program operation and nearly 100% municipal participation across the Commonwealth, the program no longer requires advancement through the tiers in order to be eligible for construction funding.
Construction grants are awarded up to $1,000,000 for eligible projects. While a prioritization plan is no longer a requirement for construction funding, the program still offers technical assistance funding up to $38,000 for communities to develop a plan if they have not done so already. Moreover, communities with previously adopted Complete Streets Policies and Prioritization Plans will receive extra consideration in funding evaluations for construction funding. Municipalities may also submit new policies and plans to be approved for this purpose. A municipality may only be awarded one grant per funding program per grant round.
Complete Streets Policies, Prioritization Plans, and Prioritization Plan Development Technical Assistance - Optional
The Complete Streets Funding Program no longer requires attending a Complete Streets 101 or 201 course, the adoption of a Complete Streets Policy, or the approval of a Prioritization Plan. While no longer requirements, we still encourage communities to attend trainings and complete these documents and submit them to MassDOT for approval as future applications for design or construction funding will be given further consideration if you have attended trainings and these documents are approved in Grant Central. We still require that a Complete Streets Policy be submitted and approved before putting together a Prioritization Plan and submitting it for approval or obtaining technical assistance.
Blowitz-Ridgeway Foundation
In the 1950s, Chicago attorney Milroy R. Blowitz and his friend, Dr. Steinman, a psychiatrist, had a dream to build a psychiatric hospital for children in Chicago’s inner city. That dream came true when Ridgeway Hospital opened its doors on Ridgeway Avenue in 1962 as a 99-bed, not-for-profit hospital focusing on the psychiatric treatment of children and adolescents.
In 1984, the Ridgeway Hospital was sold and proceeds from that sale were used to establish The Blowitz-Ridgeway Foundation, named to honor Milroy Blowitz, and the hospital he helped start. In the spirit of the Ridgeway Hospital’s original mission, the Foundation’s primary funding goal was to support non-profit agencies that provided medical, psychiatric, and psychological care to economically disadvantaged children and adolescents. The Foundation began awarding grants in 1985.
Our Mission: To significantly improve the lives and well-being of Chicago-area residents who are uninsured, underinsured, or low-income by increasing access to high-quality, comprehensive healthcare and safe, affordable housing.
Blowitz-Ridgeway Housing Grant
The Blowitz-Ridgeway Foundation focuses on funding organizations that are dedicated to preventing homelessness and providing safe, affordable housing, or organizations that collaborate with other homeless service providers and local institutions.
We help fund organizations that provide emergency shelters and transitional or permanent housing. We also fund organizations that offer support services to the homeless or unhoused like case management, counseling, job training and placement, healthcare, financial education, meals, etc.
The Foundation prioritizes small to mid-size organizations that serve the homeless where we can have the greatest impact.

Missouri Department of Conservation (MDC)
Our work began in 1937, when citizen-led efforts created the Department of Conservation to restore, conserve and regulate Missouri's over-stressed fisheries, forests and wildlife populations. During our first 40 years, hunting, fishing, and trapping permits provided most of our funding, but in 1976 an expanded program, the "Design for Conservation," was passed to set aside one-eighth of one percent sales tax directly to the agency. That consistent funding, plus a strong, non-political structure and very supportive public helped make Missouri a national leader in conservation. Today we continue our legacy of protecting our state's wild resources and helping Missourians connect with their natural heritage. Our goal is to sustain diverse, healthy plant and animal communities — well into the future.
We protect and manage the fish, forest, and wildlife of the state. We facilitate and provide opportunity for all citizens to use, enjoy, and learn about these resources.
Community Forestry Cost Share Program

Lastly, Community Forestry Cost-Share is designed to promote community forest benefits through the proper management and care of trees.
Cost-share opportunities are available beginning in July. Due to limited funding, applications are funded on a first-come, first-served basis. For more information about the cost-share opportunities, please contact your regional office.
Sodexo Stop Hunger Foundation
The Sodexo Stop Hunger Foundation goes beyond food aid to create lasting change. Through innovative programs, strategic partnerships and volunteer action, Stop Hunger tackles the root causes of food insecurity.
In 2025, Sodexo Stop Hunger Foundation and the Hunger Center awarded grants to 131 programs representing 118 communities in 37 states plus the District of Columbia. Collectively, these programs provided an estimated 22,000 backpacks full of shelf-stable food items for students to take home for the weekend or holidays when school meals are not served.
Since 2006, the Sodexo Stop Hunger Foundation has been a driving force behind weekend and holiday hunger relief for students across the U.S. Through support of food backpack programs, the Foundation partners with local food banks and schools to discreetly provide K-12 students with backpacks filled with nutritious, shelf-stable meals. These backpacks are distributed in safe, familiar settings – typically on the last school day before a weekend or school break – ensuring that all children who rely on free or reduced-price school meals don’t go hungry when school is out.
K-12 Backpack Grant
The K-12 Backpack Grant is an initiative launched by the Sodexo Stop Hunger Foundation and administered in partnership with the Congressional Hunger Center to support community backpack programs. Grants of $1,000 will be issued to community organizations with established backpack feeding programs that provide students with shelf-stable, nutritious meals when school is out of session.
