System Development Charge Methodology Updated 07-01-2023
System Development Charges (SDCs)
SDCs are a one time charge for new development. These fees are designed to recover the costs of infrastructure capacity needed to serve new development. Based on the State of Oregon Statute ORS 223.304, the charges are broken down into three components: 1) Reimbursement to recover existing facility capacity available for growth; 2) Improvement to recover planned capacity improvements for growth; and 3) Administration to recover direct costs.
All SDC fees will be adjusted annually on July 1 to account for changes in the costs acquiring and constructing facilities. The adjustment factor is based on the change in construction costs according to the Engineering News Record (ENR) Northwest (Seattle, Washington) Construction Cost Index (CCI) from December to December. The rates for SDCs have been increased by the change December 2021 to December 2022.
