System Development Charges

System Development Charges (SDCs)

SDC VisualSDCs are one-time fees assessed on new development to cover their fair share of the costs of existing and planned water, storm drainage, wastewater (sanitary sewer), transportation or parks infrastructure that provides, or will provide, capacity for growth. Local cities including Warrenton, Seaside and Cannon Beach currently have SDCs in place.

Legislative Authority SDCs are enabled by State statute (ORS 223.297-223.316) and authorized by local ordinance (23-06). 

Purpose SDCs ensure there are adequate public facilities to serve new development, pay for capital improvement projects (not operations or maintenance), are a way for new development to contribute to the costs of facilities needed to serve new development (without imposing a burden on existing development), and are not assessed on properties which are already developed unless they change use or increase in size and demand. SDCs are not taxes; they are intended to recover a fair share of the cost of existing and planned facilities that provide capacity to serve future growth. This ensures our public infrastructure keeps pace with new development by distributing the costs of increased services on new development, not on existing development.
