Frequently Asked Questions

What is stormwater?

Stormwater originates from rainfall and other precipitation that runs off of surfaces all over the Township: rooftops, streets, construction sites, lawns, fields, etc. Stormwater makes its way either along the surface or soaks into the ground. The surface water flows into swales, storm drains, and other natural water courses. As this water moves toward the streams and rivers, it can pick up things on the ground, such as pollutants, sediment, leaves, and trash.

What are the problems associated with stormwater?

At the municipal level, stormwater can cause property damage and temporarily flood roadways.

Accelerated water runoff from impervious surfaces and increased development further exacerbates the transmission of nutrients into our waterways and leads to increased flooding.

The larger problem is that stormwater outlets into our local and regional waterways. Water knows no municipal or state border and mixes with the stormwater runoff of other communities, further concentrating the pollutant load.

What is a Separated Storm Sewer System (MS4)?

Baldwin Township's Municipal Separated Storm Sewer System (commonly referred to as the MS4) is a network of inlets, pipes, swales, outlets, and other features. All of these are designed to control runoff from public streets, sidewalks, and other impervious areas. The storm sewer system plays an important role in keeping roads free of flowing or ponding water and ice, making it a key piece of public infrastructure.

What does the Township do to address stormwater problems?

The Township maintains a complete stormwater program that complies with the guidelines, or Minimum Control Measures, developed by the Pennsylvania Department for Environmental Protection (DEP). These guidelines mandate:

What do Township residents have to do about stormwater problems?

First and foremost, Township residents have to comply with stormwater management ordinances.

Any construction activity within the Township that creates new impervious surface requires a stormwater management plan be submitted and approved by the Township before any work takes place. The intent of the ordinance is to limit the amount of stormwater runoff to no more than pre-development levels.

See Chapter 9 - Grading and Excavating and Chapter 17 - Stormwater Management of the Baldwin Township Municipal Code for more information.

Are there other ways Township residents can become involved?

Yes, there are several ways you can become more active in the Township's efforts to keep our water clean and our roads passable. Below are are few options.
