   Community Services - Storm WaterBy 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 has approximately 138 catch basins, 927 drop inlets, 3,958 curb inlets, 3,014 manholes, and 4,433 culverts in the public right-of-way.  This is all within the more than 200 miles of Township roads, and does not include State or County highways.

Storm water management is evolving to the point that it could become a public utility much like sanitary sewers are today.  The first step toward this was implemented in 2003 with the creation of the Butler County Storm Water program.  Currently, each property in West Chester is assessed an annual fee for the monitoring of the quality of storm water runoff.  As development continues and existing storm water systems age, it will become necessary to establish a similar program to monitor and maintain the quantity of storm water.


Storm Water Assets


Curbs: 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.

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 roadway or parking lot where basins are installed.

Drainage Ditches: These are generally the responsibility of the homeowner or homeowners association, unless the ditch is specifically designated as a public drainage easement.

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 typically the homeowner's responsibility.

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



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