Grant Money Availiable For Environmental Enhancement Projects.

The Stanislaus County Environmental Trust Fund has $5,000 in grant monies available for projects, activities, and equipment or supplies that benefit the natural environment and resources in Stanislaus County.

The Environmental Trust Fund was established by the County Board of Supervisors in 2001, to receive monies to be made available to fund projects involving all areas related to the enhancement of Stanislaus County’s natural resources. The Environmental Trust Fund has awarded over $245,000 in grants over the past 17 years to non-profit, private, and municipal applicants for use towards environmental restoration and protection projects.

Grant Project Applications are currently being accepted for qualified projects up to $5,000. Qualified applicants can be from environmental law enforcement agencies, non-profit, or volunteer organizations and award monies can be used for such things as funding restoration projects or youth activities, and purchase equipment and supplies for use in projects that benefit the enhancement of natural resources within the County of Stanislaus.

Eligible projects requesting grant monies for the purpose of funding environmental enhancement activities must relate to the improvement and/or beautification of Stanislaus County’s natural resources. Applications for projects related to environmental law enforcement must improve the agencies’ environmental investigative efforts, and may not be used to pay staffing costs.
