The West Chester Borough Council Public Works Committee will discuss adding a storm water assessment fee based on impervious coverage on Monday.
The borough would use the fee to offset costs associated with storm water management as well as the loss of an annual usage fee of nearly $800,000 from the Pfizer property.
Borough Council has also discussed using the fee as a way to "tax" some of the nonprofits located withing the borough's boundaries.
Currently, the borough is nearly 100 percent developed with 35 percent of the borough's land used by tax-exempt non-profits.
If approved on Monday, the new storm water fee would be moved onto full council next week.
