Impact Fees
Contents
Introduction
Impact fees are charges assessed by local governments against new development projects that attempt to recover the cost incurred by government in providing the public facilities required to serve the new development. Impact fees are only used to fund facilities, such as roads, schools, and parks, that are directly associated with the new development. They may be used to pay the proportionate share of the cost of public facilities that benefit the new development; however, impact fees cannot be used to correct existing deficiencies in public facilities. In Washington, impact fees are authorized for those jurisdictions planning under the Growth Management Act (RCW 82.02.050 - .100), as part of “voluntary agreements” under RCW 82.02.020, and as mitigation for impacts under the State Environmental Policy Act (SEPA – Ch. 43.21C RCW). GMA impact fees are only authorized for: public streets and roads; publicly owned parks, open space, and recreation facilities; school facilities; and fire protection facilities in jurisdictions that are not part of a fire district. Setting fee schedules for impact fees is a complex process typically involving rate studies; generally, impact fees do not recover the full cost of a new facility since these fees must be directly and proportionately related to impacts associated with new development.
In 2009, the Legislature adopted SB 5580, Chapter 263, Laws of 2009, which extends the time period for expenditure of school impact fees to 10 years.

State Statutes and Administrative Regulations - Impact Fees
Three statutes provide the primary authority for impact fees imposed by cities and counties:
- RCW 82.02.050 - .100 - Impact fees authorized under the Growth Management Act -
- RCW 82.02.020 – Voluntary agreements
- Ch. 43.21C RCW - State Environmental Policy Act (Mitigation Measures) RCW 43.21C.060 and RCW 43.21C.065
Washington Administrative Code
- WAC 365-195-850 – Impact Fees
- General - James T. James v. Kitsap County, 154 Wn.2d 574 (2005) - The imposition of impact fees as a condition of building permit issuance is a "land use decision" subject to the Land Use Petition Act (LUPA), and thus must be challenged within 21 days.
- General - Pavlina v. City of Vancouver, 122 Wn. App. 520 (2004) - [Assessment of development impact fees] - Even though preliminary plat approval occurred before an impact fee ordinance was adopted, the fees could be imposed when the developer applied for a building permit. Impact fees are not an additional condition of approval. That the developer’s plan previously received preliminary approval does not preclude imposition of impact fees when a building permit is sought.
- General - Nolte v. City of Olympia, 96 Wn. App. 944 (1999) - A city may not impose impact fees on projects outside of its borders. However, if a city enters into a utility extension agreement (UEA) based on the promise to pay impact fees that are later found to be invalid, the city is relieved of its duty to perform under the UEA.
- General - Vintage Construction Co. v. Bothell, 83 Wn. App. 605 (1996) - A land developer sought to recover fees paid to a city in lieu of dedication of land that were imposed on the developer as a condition of subdivision approval. The court held that the city's failure to determine, in a site-specific manner, the value of the land the developer could have been required to dedicate rendered the fees in lieu of dedication invalid. This case provides a clarification of two earlier cases concerning impact fees: Henderson Homes v. Bothell, 124 Wn.2d 240 (1994), and Trimen Development Co. v. King County, 124 Wn.2d 261 (1994).
- Schools - Wellington River Hollow v. King County, 113 Wn. App. 574 (2002) - [Impact Fees] - It is not unconstitutional for jurisdictions within a school district have discretion to impose school impact fees on new developments, even though the amount of fees for comparable units will differ from one jurisdiction to another within the same school district.
- Schools - West Coast, Inc. v. Snohomish County, 104 Wn. App. 735 (2000) - [Preliminary Plats/Modification/Impact Fees] - A condition of preliminary plat approval, in this case school impact fees, is tantamount to a contractual obligation that is binding on the applicant absent extraordinary circumstances justifying a failure to perform.
- Transportation - City of Olympia v. Drebick, 156 Wn.2d 289 (1/19/2006) - [Calculation of development fees under GMA] The state supreme court upheld the city's calculation of transportation impact fees imposed under GMA, reversing a decision by the court of appeals (119 Wn. App. 774 (2004)). The GMA impact fee statutes permit local governments to base impact fees on area-wide infrastructure improvements reasonably related and beneficial to the particular development seeking approval. This standard is broader than the standard under SEPA or the Local Transportation Act. The city was not required to calculate the impact fee by making individualized assessments of the Drebick development's direct impact on each improvement planned in a service area. The city's method of calculating transportation impact fees complied with the plain language of the GMA impact fee statutes.
- Transportation – New Castle Invs. v. City of LaCenter, 98 Wn. App.224 (1999) - [Transportation Impact Fee Ordinance] - A city's transportation impact fee ordinance is not subject to the vesting statute for subdivision applications, RCW 58.17.033, because transportation impact fees do not fall within the definition of "land use control ordinances" Under that statute. Consequently, the city's impact fee can be applied to a proposed development even though the application for preliminary plat approval was completed prior to the effective date for the city's ordinance.

Most Growth Management Hearings Board decisions address the fact that impact fees imposed under Chapter 82.02 RCW are not within the board’s jurisdiction.
