Stormwater Management

The City of Hilliard is dedicated to the protection of our streams and water resources, and we encourage our residents to support these efforts. The city is located within two watersheds: the Scioto River watershed and the Big Darby Creek watershed. We have been working to address drainage management, water quality management and stormwater regulation compliance.

Pollutants of Concern

The items of concern identified by Ohio EPA under its TMDL Program are:

Total Maximum Daily Loads (TMDLs) specify the amount a pollutant needs to be reduced in order to meet water quality standards, allocate pollutant load reductions, and provide the basis for taking actions needed to restore a water body.

• excess nutrients from lawn care, yard waste, and animal and human waste.
• sediment from erosion from construction and unstable stream banks.
• bacteria from animal and human waste.
• phosphorus and E. coli, specifically in Big Darby Creek.

Take Action! What You Can Do To Help

We all have an important role in the protection of our streams and water quality. Please minimize your impacts by:

• removing yard waste and leaves from street gutters and storm drains.
• using fertilizers and pesticides sparingly and properly, and sweeping all excess off sidewalks, driveways and streets.
• bagging pet waste and disposing of waste in the trash.
• https://www.franklinswcd.org/pupdirecting downspouts to rain barrels or rain gardens.
• planting native trees, shrubs and perennials
• washing your car on grass, gravel or at a car wash.
• maintaining your aerator and septic system; for more information on managing sewage treatment systems.
• reporting all pollution and spills appropriately (see below).
• encouraging community groups to support our work with a stream clean-up, tree planting or another activity. If you know of an interested group, please contact Franklin SWCD.
• learning more and testing your knowledge.
