Happy Valley/Clackamas County Joint Area TSDC
In January 2002, Clackamas County and the City of Happy Valley adopted a TSDC Ordinance, Capital Improvement Plan and Methodology to create the new Happy Valley/Clackamas Joint TSDC Area. This area is bordered by I-205 on the west, Multnomah County on the north, approximately 172nd Avenue on the east and Highway 212 on the south. The joint district has its own TSDC fee schedule to fund capital improvements needed within its boundaries to accommodate growth.
The Board of County Commissioners and the City of Happy Valley adopted an updated TSDC ordinance and methodologies in December 2006, and an updated capital improvement plan in January 2006.
TSDC fees are subject to change as early as March of each year. Call Lori Phillips at 503-742-4331 for more details.

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.
Clackamas County has an ordinance implementing a Parks System Development Charge on any new dwelling units created within the NCPRD District. A special rate is assessed for residential units in the boundaries of Sunnyside Village.
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 this source of demand.
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.
