53 Pa. Stat. § 2807
The payment of damages sustained by the changes provided for in this act, in the course or channel of any creek, run or natural waterway, may be made, either in whole or in part, by the borough or city, or in whole, or in part, by assessment upon the property benefited by such improvements, as said viewers may determine and the court approve; and, in the latter case, the viewers appointed to assess damages, having first estimated and determined the same, together with the costs and expenses thereof apart from benefits, shall also assess the said damages, costs and expenses, or so much thereof as they may deem just and reasonable, upon the properties peculiarly benefited by the improvement, including in the said assessment all properties for which damages have been allowed, if in their judgment such properties shall be benefited thereby, and shall report the same to the said court. The total assessment for benefits shall not exceed the total damages and cost of such change or improvement.
