The North Clackamas Park and Recreation District (NCPRD) provides a variety of park and recreational facilities, and a wide range of services including: aquatics, community athletics, special events and specialized recreation programs. District parks, facilities and services are important community resources benefiting both existing and future park district residents, businesses, employees and visitors.
The NCPRD recognizes the impact of business employees on the need for new capital facilities and has determined that it is in everyone’s best interests to also seek some contribution to those needs from commercial developments.
System Development Charges are one-time fees charged to new development to help pay a portion of the costs associated with building capital facilities to meet needs created by growth. The PSDC fee is based on the specific impact a development is expected to have on the District’s population and employment.
PSDC fees are subject to change as early as February of each year.
