Picture_1935webBy law, townships are responsible for the maintenance of open ditches, culverts, catch basins, pipes and curb inlets located within the public right-of-way.

Right-of-way is normally 25 feet from the center of the roadway.

West Chester Township infrastructure includes:

  • 222 miles of road and 630 cul-de-sacs,
  • 6,900 storm pipes, which is nearly 580,000 lineal feet of pipe,
  • 180 culverts, which is almost 10,400 lineal feet of pipe,
  • 5,000 catch basins that serve as either inlet or outlets for storm water 

Pipes and catch basins on private property are the responsibility of the property owner or in some cases the Home Owners Association or Property Owners Association.


It is critically important to take care of storm water assets on your property. Proper maintenance can prevent serious damage to these assets and prevent property flooding for you and your neighbors.

Clearing debris from local streams is the responsibility of the property owner whose land abuts or is traversed by the stream.

By removing debris from local streams, the water flows within its channel and erosion is prevented. 


Storm Water Assets

Picture_0432webCurbs: Curbs are designed to carry road drainage and are maintained as part of street resurfacing.

Culverts: Culverts are replaced when failure occurs – CMP (metal) pipes last about 30 years. Plastic and concrete pipes have a longer life expectancy.

Catch basins: The owner of the road along which catch basins are situated is responsible for maintaining them. That could either be the Township, the Butler County Engineer's Office, the subdivision developer, or the owners of a private road or parking lot where basins are installed.

Drainage ditches: These are generally the responsibility of the homeowner or HOA, unless the ditch is specifically designated as a public drainage easement within the right-of-way..

Pipes and culverts underneath roadways: The owner of the road assumes responsibility for these facilities. On private roads, or in newer subdivisions where the roads have not yet been accepted by the Township, it is the homeowner's or the developer's responsibility. On public roads, it is the responsibility of the Township, the County or the State where applicable.

Driveway pipes and culverts: These are the homeowner's responsibility.

Detention facilities: Detention and retention ponds in residential neighborhoods are the responsibility of the HOA. Detention and retention facilities in non-residential areas are the responsibility of the private establishments they serve. Developers are typically responsible for detention and retention pond maintenance in newly developed neighborhoods until they are turned over to the HOA.
