Resources By State

Funding and Financial Resources

Funding refers to grants, loans, and other financial tools that help communities plan, build, and maintain stormwater infrastructure.

• State environmental or natural‑resources agencies often host or link to stormwater‑related funding programs, such as revolving‑loan funds, green‑infrastructure grants, or watershed‑improvement grants that can support stormwater projects.
• Regional stormwater centers, nonprofits, and federal‑state partnerships may also offer competitive grants for pilots, retrofit projects, or capacity‑building, and state stormwater pages typically curate links to these opportunities so local governments and watershed groups can find appropriate support.

Fact Sheets

Fact sheets are short, easy‑to‑read documents that explain stormwater basics, common pollutants, and simple practices communities and residents can use to reduce runoff impacts.

• They usually cover topics like how stormwater becomes polluted, differences between sanitary sewers and storm drains, and examples of green stormwater infrastructure (rain gardens, permeable pavement, bioswales) versus conventional controls.
• States, cities, and university‑based stormwater centers often publish fact sheets aimed at homeowners, contractors, schools, and local governments, making them one of the most common entry‑level resources on state stormwater pages.

Regulations

Regulations are the binding rules that govern how stormwater must be managed on construction sites, transportation projects, and municipal systems.

• At the federal level, most states administer stormwater programs under the National Pollutant Discharge Elimination System (NPDES), often through a state‑run permit program (for example, a state‑specific “Pollution Discharge Elimination System” or similar name).
• States then translate these federal requirements into small MS4 permits, construction‑site regulations, post‑construction standards, and local ordinances; many stormwater web portals for each state prominently link to these permits, technical guidance manuals, and inspection/compliance protocols.
