The Mercer County Improvement Authority plays an invaluable role enhancing the quality of life for all Mercer County residents. In 1967, the Mercer County Improvement Authority was created under County Improvement Authorities Law to undertake certain projects for the benefit of the residents of Mercer County.  As such, programs and services are available to assist the County, municipalities, school and fire districts, and not-for-profits in the areas of financing, project management, redevelopment, solid waste and recycling. The Authority has been an integral component in many of the projects undertaken in this county, and has provided the necessary expertise to ensure success.

Please visit our website to learn about programs and services available through the Mercer County Improvement Authority.
