Stormwater Charges as User Fees: Proportionality, Proxy Metrics, and Limits on Recoverable Costs (Wecht, J., Concurring and Dissenting)

1. Introduction

This Pennsylvania Supreme Court matter arose from the Borough of West Chester’s imposition of a “stormwater charge” intended to fund management of stormwater flows within the municipality. The Pennsylvania State System of Higher Education and West Chester University (collectively, the “University”) refused payment, asserting the charge was a tax—and thus barred by governmental/sovereign immunity—rather than a fee for services rendered.

Justice Wecht’s opinion is concurring and dissenting: he agrees with the Majority only on allocation of the burden of proof at summary judgment, but rejects the Majority’s conclusion that the stormwater charge is a tax. He would treat the charge as a service fee payable by the University, applying a proportionality-centered analysis and rejecting reliance on the Environmental Rights Amendment (“ERA”) and generalized public policy arguments as irrelevant to the tax-versus-fee classification question.

Key Issue

  • Classification: Is the Borough’s stormwater charge a tax (immune) or a fee (payable)?
  • Method: If it is a fee, is it reasonably proportional to the benefit and properly costed?

2. Summary of the Opinion

Justice Wecht:

  • Concurs that the Commonwealth Court properly placed the burden of proof on the Borough on cross-motions for summary judgment.
  • Dissents from the Majority’s holding that the charge is a tax merely because the Borough acted “in its public capacity.”
  • Would hold the stormwater charge is a fee, because the University benefits from the municipal stormwater system and the charge can be assessed using a practical proxy (impervious surface area) and limited to costs reasonably related to operation and maintenance.
  • Rejects using the Environmental Rights Amendment or free-form public policy arguments to decide the tax/fee question.

3. Analysis

A. Precedents Cited

1) Service charges may be fees when tied to use/benefit

Justice Wecht situates stormwater management alongside other municipal utility-like services historically treated as fee-supported services:

  • Supervisors of Manheim Twp. v. Workman, 38 A.2d 273 (Pa. 1944): Cited for two linked propositions: (i) a charge is evaluated for reasonable proportionality to the service; and (ii) when direct measurement of use is impractical, a municipality may employ a proxy metric (there, street frontage was discussed as a permissible basis given the impossibility of measuring “amount of streetlight” used).
  • Sw. Delaware Cnty. Mun. Auth. v. Aston Twp., 198 A.2d 867 (Pa. 1964): Cited for the principle that even governmental entities (there, a school district) may be required to pay “sewer rentals,” reinforcing the conceptual category of municipal utility charges as fees for services rather than taxes.

2) The “tax vs. fee” line turns on reasonableness and relation to service—not labels

  • In re City of Philadelphia, 21 A.2d 876 (Pa. 1941): Central to Justice Wecht’s proportionality framework. He highlights two holdings from that decision:
    • A sewer charge based on water use can be acceptable because water inflow is “apt to be roughly proportional” to sewage outflow—endorsing proxy metrics when they reasonably track use.
    • A charge based on assessed property value bore no relation to the service and pushed the charge into tax territory.
    Justice Wecht uses In re City of Philadelphia to argue that the proper inquiry is not whether government acts “publicly,” but whether the charge’s basis and cost components relate to service and use.

3) Fees cannot be disguised special assessments; costs must be properly scoped

  • In re City of Philadelphia, 21 A.2d at 879: Cited for the constraint that a charge must be based on extent of use rather than “the cost of furnishing the facilities,” signaling the boundary between fees and disguised assessments.
  • GSP Mgmt. Co. v. Duncansville Mun. Auth., 126 A.3d 369 (Pa. Cmwlth. 2015): Cited as an intermediate appellate example that even when a municipality may impose sewer fees, an unreasonable amount relative to service can render the charge an unauthorized tax.
  • M&D Properties, Inc. v. Borough of Port Vue, 893 A.2d 858 (Pa. Cmwlth. 2006): Cited for the complementary point that trash collection fees were upheld as reasonable—reinforcing that reasonableness/proportionality is the hinge.

4) Sovereign immunity from local real estate taxes frames the University’s defense

  • City of Philadelphia v. Cumberland County Board of Assessment Appeals, 81 A.3d 24 (Pa. 2013): Cited for the general statement that Commonwealth arms and subdivisions enjoy sovereign immunity from local real estate taxation. Justice Wecht invokes this to clarify what is at stake: if the stormwater charge is a tax, immunity attaches; if a fee, it does not.

5) Environmental Rights Amendment authorities are cited—then cabined

  • Pa. Env't Def. Found. v. Commonwealth, 161 A.3d 911 (Pa. 2017), and Robinson Twp. v. Commonwealth, 83 A.3d 901 (Pa. 2013): Justice Wecht quotes these ERA cases only to explain what the ERA generally does, then expressly declines to use the ERA as a tool to classify the charge as a tax or fee.

6) Record context from the intermediate court

  • Borough of West Chester v. PASSHE, 291 A.3d 455 (Pa. Cmwlth. 2023): Cited for factual/record context about what stormwater management can entail (environmental restoration, runoff prevention, flow direction, pollution minimization), which informs what cost categories may be “reasonably related.”

B. Legal Reasoning

1) The Majority’s stopping point: “public capacity”

Justice Wecht criticizes the Majority’s approach for ending the analysis once it concludes the Borough is acting in its public capacity, treating that as dispositive that the charge is a tax. In his view, that collapses the tax/fee inquiry into a formalistic premise: municipalities almost always act publicly, but that cannot mean municipal service charges are always taxes.

2) The dissent’s core test: reasonable proportionality to benefit/use

Justice Wecht endorses a functional test: whether the charge is reasonably proportional to the benefit received from the stormwater system. He breaks this into two operational questions:

  1. Assessment basis: Is the metric used to allocate charges a reasonable approximation of use/benefit?
  2. Recoverable costs: Are the cost components charged to users properly related to operating and maintaining the service, rather than impermissibly funding a local benefit as a disguised special assessment?

3) Impervious surface area as a permissible proxy metric

The opinion identifies impervious surface area as a reasonable and perhaps uniquely practicable basis for allocation, because it correlates with runoff generation and system burden. He relies on the principle (from Supervisors of Manheim Twp. v. Workman and In re City of Philadelphia) that where precise metering is impractical, an associated and rational proxy is acceptable.

4) Limits on the cost pool: no disguised special assessments; “reasonably related” costs allowed

Justice Wecht draws a line between:

  • Impermissible: grounding the charge on the “costs of constructing a local benefit,” which would operate like a special assessment “in disguise.”
  • Permissible: imposing costs “reasonably related” to maintenance and operation of the stormwater system on large-scale users.

Importantly, he views stormwater impacts as diffuse and geographically unbounded—meaning reasonable stormwater system costs may include measures not confined to a single parcel’s boundary (e.g., runoff prevention and environmental restoration) so long as they are truly part of system operation/maintenance and not merely a capitalized local benefit charge.

5) ERA and public policy are excluded from the classification inquiry

Justice Wecht treats the ERA’s possible relevance to municipal stormwater duties as a separate constitutional question that is “beyond the scope” of the tax/fee classification dispute. He warns that importing the ERA risks “constitutionaliz[ing] a non-constitutional dispute” and may create downstream interpretive problems. Similarly, he rejects public policy balancing as having “no place” in the analytical framework for distinguishing taxes from fees, which he presents as a doctrinal/legal test rather than a policy choice.

C. Impact

Although nonbinding as a concurring/dissenting opinion, Justice Wecht’s analysis is a roadmap for future litigants and courts confronting stormwater charges levied against tax-immune entities:

  • Doctrinal refinement: It reframes “stormwater charge” cases around proportionality and cost nexus rather than the municipality’s “public capacity,” potentially narrowing the path to characterizing such charges as taxes.
  • Administrative design: Municipalities may draft ordinances with explicit findings tying impervious area to runoff burden and delineating operation/maintenance cost categories, to strengthen the argument that the charge is a fee.
  • State-entity exposure: If adopted by future majorities, the approach would make it harder for Commonwealth-related institutions to avoid paying for stormwater systems from which they benefit—similar to “sewer rentals” and waste-management charges.
  • ERA litigation containment: The opinion counsels restraint in using the ERA as an all-purpose support for municipal environmental funding mechanisms, potentially influencing how parties frame stormwater disputes to avoid constitutional entanglement.

4. Complex Concepts Simplified

Tax vs. fee
A tax primarily raises general revenue for government and is often not tied to a particular service used by the payer. A fee charges for a service or benefit and is justified by a relationship between what is paid and what is received.
Sovereign/governmental immunity (in this context)
Many Commonwealth entities are immune from local taxation. If the stormwater charge is a “tax,” the University does not pay; if it is a “fee,” it can.
Reasonable proportionality
The charge should be reasonably aligned with the payer’s use of or benefit from the service. Exact precision may not be required, but arbitrariness can convert a fee into a tax.
Proxy metric (impervious surface area)
When direct measurement is impractical, government may use a reasonable substitute that correlates with service usage. Impervious surfaces (roofs, pavement) tend to increase runoff.
Special assessment
A charge imposed to fund a particular local improvement benefiting specific properties. Justice Wecht cautions that a “fee” cannot secretly operate as a special assessment by funding construction costs as such.
Environmental Rights Amendment (ERA)
Pennsylvania’s constitutional environmental provision (Pa. Const. art. I, § 27). Justice Wecht treats it as irrelevant to whether a charge is a tax or fee in this appeal.

5. Conclusion

Justice Wecht’s concurring and dissenting opinion advances a clear doctrinal frame: stormwater charges should be classified by their relationship to service/benefit, assessed through reasonable proportionality, including (when necessary) the use of proxy metrics like impervious surface area and a disciplined definition of recoverable costs as those “reasonably related” to operation and maintenance rather than disguised assessments. He simultaneously urges restraint—excluding the ERA and broad public policy from the tax/fee analysis—to keep the dispute within established municipal finance doctrine. Even as a nonmajority writing, it provides a structured template for future stormwater-fee litigation in Pennsylvania.
