Description
This program provides financial assistance to Pennsylvania counties and municipalities for the development, revision, administration, and implementation of watershed-based stormwater management plans, as mandated by the Pennsylvania Stormwater Management Act (Act 167 of 1978). The grant is administered by the Pennsylvania Department of Environmental Protection (DEP) and is structured in two main phases:
- Phase I: Funding for the development of a scope of study for an Act 167 Plan.
- Phase II: Funding for the preparation or revision of the full watershed stormwater management plan.
Following plan approval, counties must ensure that relevant land use and infrastructure projects comply with the adopted plan. Municipalities within counties with current, DEP-approved Act 167 Plans may also receive partial reimbursement for eligible administrative, enforcement, and implementation costs related to aligning local ordinances with the county plan. The program aims to reduce flooding, improve water quality, and promote sustainable development through coordinated stormwater management.
