About the Project
Kingston Terrace Master Plan
The City of King City is launching the Kingston Terrace Master Plan, an effort to guide future growth and development in the 528-acre Kingston Terrace area. During this process, the City will work with community members to refine the community’s vision, as initiated in the Concept Plan, for this area. The planning process will produce policies, Comprehensive Plan and Community Development Code (CDC) amendments, and implementation measures resulting in an area that provides:
a vibrant, walkable, and complete community where every day needs are easily accessible.
housing choice and affordability for all current and future residents.
safe, efficient, convenient, and reliable transportation choices to enhance connectivity and minimize automobile dependency.
protection of environmentally sensitive lands and retention of healthy ecosystems.
the efficient and equitable provision of infrastructure and associated costs.
Originating as a retirement community, King City has diversified in regards to race, ethnicity, and age, and has experienced a 96% growth in population from 2000-2017. To accommodate this rapid growth, King City identified Urban Reserve Area 6D as a potential site for expansion. King City completed the King City Urban Reserve Area 6D Concept Plan in spring 2018, which created an initial vision to urbanize the area. Following the Concept Plan, Metro approved the expansion of the UGB to include the Urban Reserve 6D Area. Now, the Kingston Terrace Master Plan will be a tool for city leaders to direct and manage the development of the area, creating a truly 24-hour city complete with a variety of housing, employment, commercial, transportation, and recreational opportunities.
With the start of the Kingston Terrace Master Plan, the area is now referred to as Kingston Terrace. The area is bounded by the current King City city limits to the east, Beef Bend Road on the north, the Tualatin River/Elsner Road on the south, and Roy Rogers Road to the west.

March to June 2023 – Transportation System Plan adoption process
April to July 2023 – Kingston Terrace Master Plan adoption process
June to September 2023 – Community Development and Zoning Code adoption process
June to September 2023 – System Development Charge Methodology adoption process
Adoption processes will include opportunities to provide testimony at Planning Commission and City Council hearings.
Related Projects
Clean Water Services
Clean Water Services (CWS) has been involved in local planning activities in the South Bull Mountain area, which includes the River Terrace South and Kingston Terrace planning areas, in coordination with the cities of Tigard and King City as well as Washington County and Metro. To that end, summaries of CWS’ current planning efforts are below. For more information on these projects, contact CWS, at southbullmtnplanning@cleanwaterservices.org.
Stormwater
Due to the complexity of the area’s geography and all-encompassing nature of stormwater, an inter-city stormwater strategy is necessary to provide a more comprehensive approach to stormwater management. This regional strategy, which will include the River Terrace South and Kingston Terrace planning areas, will also lay the ground work for better coordination between local governments and with the community.
The stormwater study results will be used to determine what options are feasible for stormwater management in the South Bull Mountain area. It will also include recommendations to consider for stream enhancement and retrofits to mitigate existing impacts to local streams, although it is too early to identify specific project funding opportunities, CWS will engage city partners to discuss implementation once the study is complete. The study is anticipated to be complete in late winter 2022, and will provide guidance to local jurisdictions as they plan for future projects. Additionally, for all newly built facilities, CWS requires adherence to their Design & Construction standards. These new standards were developed in 2019 to further minimize environmental impacts from new construction and prevent damage by development to streams and soil.
Sanitary Sewer
The sanitary sewer strategy will comprise a mix of technical analysis, cost considerations, and stakeholder input to recommend where sanitary infrastructure may be best located to provide for future development. The analysis will include approaches to minimize impact to streams, private property, and habitat while providing for the best use of public investments in our sanitary infrastructure. The strategy is expected to be completed in late winter of 2022. CWS will continue working with all stakeholders as the strategy is completed and the tasks of design and construction begin in the coming years.
King City Middle Housing Project
The King City Middle Housing Code Update project began in December of 2020 and concluded in August 2021. The project updated the King City Comprehensive Plan (Plan) and Community Development Code (CDC) to fully comply with the Oregon State House Bill 2001 for Housing Choices. The objectives of this project included:
Further expand the range of middle housing types, including duplexes, triplexes, quadplexes, townhouses and cottage clusters, which are to be allowed and encouraged citywide.
Streamline the review and approval process with clear and objective standards for middle housing.
Update dimensional standards and design criteria so they are consistently and fairly applied to all types of residential construction.
Updates resulting from this project will be incorporated into a larger city-led project to update the Plan and CDC overall. In addition to complying with HB 2001, the update will improve the code organization to facilitate necessary amendments over the next several years related to the King City Transportation System Plan (TSP) and Kingston Terrace planning efforts.
King City Transportation System Plan
The King City Transportation System Plan (TSP) plans for the next 20 years of transportation needs in King City, including the Kingston Terrace area. The final TSP will be adopted concurrently with the Kingston Terrace Master Plan.
King City Urban Reserve Area 6D Concept Plan
In 2018, King City completed the King City Urban Reserve Area 6D Concept Plan as a guiding document for urbanizing the area. In the Concept Plan, a series of baseline reports were conducted in which the City addressed housing, land uses, transportation routes, parks and open spaces, public facilities, governance, and infrastructure costs for Urban Reserve Area 6D -now known as Kingston Terrace. This analysis showed why the UGB expansion was necessary and how the City would meet Metro requirements in the expansion process. King City engaged the public during the Concept Plan’s development through the formation of a Stakeholder Advisory Committee, open-houses, and a week-long charette. Following the Concept Plan, Metro approved the addition of Urban Reserve Area 6D into the UGB in December 2018.
The community engagement efforts for the Concept Plan resulted in a community vision for the area’s different neighborhoods, and related land uses, of the new Kingston Terrace area (shown in the figures below). The Kingston Terrace Master Plan builds on the Concept Plan to detail and implement these visions through Comprehensive Plan and Community Development Code amendments.
