Transportation System Plan


As a City with a population over 5000 King City is charged with preparing and adopting a Transportation System Plan (TSP) in accordance with ORS 183, 195, 197, OAR 660 Division 12, Statewide Planning Goals particularly Goal 12, and the Metro Regional Functional Plan.

So, what is a Transportation System Plan or TSP?

A Transportation System Plan (TSP) is a model framework that guides future development and ensures the costs associated with future development are borne by those developing their lands. The TSP sets aside a list of capital improvements through the year 2045 that will need to occur to ensure the impacts associated with growth are mitigated and do not unduly impact current residents.

King City’s newly adopted Transportation System Plan has been reviewed and studied by no less than three (3) traffic engineering firms, multiple Land Use Planners & Environmental Scientists and has been deemed to be the best solution for the approved land uses and development plans. The adopted TSP is an environmentally sensitive and sound plan, balancing current and projected future traffic loads over a network of streets, reducing cut through traffic, mitigating impacts, providing access to parks, trails, and natural spaces, addressing erosion problems, and preventing condemnation of properties within King City and along Beef Bend Road.

King City, their consultants and engineers designed the transportation network to provides equitable outcomes for King City residents, ensuring effective response times for Emergency Services, reducing cut through traffic, protecting and insulating our seniors and vulnerable communities, providing requisite infrastructure necessary to support the future growth, providing local transit possibilities, access to Parks, Trails, Natural Areas, putting in place Erosion Control Mechanism and Ultimately Designing Cohesive Neighborhoods.

What is relevant about King City’s Transportation System Plan?

  • The City Council in cooperation with and utilizing the expertise of their consultants expended considerable resources (⋍$1.2 Million in grant funds) to design an equitable transportation network that identified a couple east-west corridors with the intent to ensure a net zero loss to current residential housing.
  • The Southern East-West Corridor provides critical infrastructure connections and provides access to the Tualatin River, Parks, Trails, and Natural Spaces for all future City Residents to enjoy.
  • The TSP balances traffic loads equally across the entire network resulting in no profile modifications being necessitated to the current portions of Fischer Road between its terminus at the PGE/Bonneville Power Lines and Queen Anne.
  • The network enhancements and intersection spacing along with other impediments ensure the character and nature of Ficher Road would not change and the profile would remain as it currently exist.
  • The profile extending beyond the terminus at the PGE power lines would be One Eastbound lane, One Westbound lane, and a Separated Multiuse Path on the south side to a projected terminus near the proposed 155th
  • The Southern E-W Corridor is comprised of a network of roads and intersections that link our planned neighborhoods and make up a corridor that is NOT a direct route from Roy Rogers to 99W.
  • Because the TSP balances the traffic loads equally across the network there are no profile modifications necessary to portions of Beef Bend Road between 131st and 99W (Exception 99W intersection), thereby protecting the single-family dwellings, apartments, condos & mobile homes on the north and south side from being condemned and razed to the ground, thereby saving and protecting existing housing.
  • One point of contention has been the Bankston Private Easement. In accordance with the code language adopted with the TSP & Kingston Terrace Master Plan (KTMP) in the Community Development Code Section 16.114.120(C)1, certain deviations and variances would allow type A intersections along the corridor to adjust the overall alignment up to 100 LF in any direction, providing as needed, a pathway to avoid environmentally sensitive areas or challenging terrain or in this case potentially the Bankston Private Easement area. (See TSP MAP)
  • Additionally, in accordance with the code language adopted with the TSP & KTMP in the Community Development Code Section 16.114.120(C)2, certain deviations and variances would allow type B intersections throughout the plan area to adjust the overall alignment of other corridors up to 200 LF in any direction, providing as needed wider deviations if necessary. The map above reflects the different intersections as identified in the City’s TSP. (See TSP MAP)
  • The newly adopted Comprehensive Plan designates the Bankston Property as a Future Community Park, thereby protecting the easement areas from future development and providing park lands for future residents to enjoy.
  • The adopted plans were widely supported by the City Council, Community Members, Metro, Washington County, Tigard, Sherwood, & Tualatin. The plans will ensure King City growth is conducted in a sustainable and equitable manner over the next 20 years.
  • Over the past 7 years of planning individuals voiced concerns regarding the city’s intentions to allegedly build the southern east-west corridor prior to a triggering development along the corridor. The City Council and Staff believe and have explained that road construction typically occurs concurrent with development, and in King City’s 60-year history the City has not taken it upon themselves to build a road. Roads are built to serve developments as development occurs and are built by property owners and developers.
  • All current and future development is subject to appropriate regulatory permitting, which includes compliance with local, regional, state and federal agencies such as: USACE, DSL, DEQ, DLCD, ODFW, ODOT, USDFW, NMFS, NOAA, The Confederated Tribes, SHPO, DOGOMI, Metro, Washington County, Clean Water Services and King City regulations.
  • The City Council carefully considered the public input and the advice of their staff, consultants, engineers, and scientists through the Transportation System Plan process spanning the past 4 years and the Kingston Terrace Concept and Master Plan process over the last 6 years, their decision was based on modeling data, scientific evidence and the best advice from experts in their fields.

What does the City Council want you to know?

King City is required by State and Regional Laws to have in place a Transportation System Plan and Master Plan that provide a model framework to guide development into the future and through 2045.

The Decision to adopt the TSP was based on the information contained within the bullet list above and the thousands of pages of information that can be found under the “Documents” tab below. The City Council has no intentions of building roads between 150th and the River/Watson intersection, and further would not do corridor improvements unless a triggering event along the corridor necessitated City involvement and King City does not expect that area to develop for a significant period of time.

The Transportation System Plan is the combined product of no less than three (3) traffic engineering firms, multiple Land Use Planners & Environmental Scientists and is their best recommended solution for the approved land use plans, protecting environmentally sensitive lands, balancing the traffic loads on a network of streets, reducing cut through traffic, mitigating impacts, providing access to parks, trails and natural spaces, addressing erosion problems and preventing condemnation of properties within King City and along Beef Bend Road.

The Transportation System Plan under 16.114.120(C), provides enough deviation or variance of the southern E-W Corridor to avoid the Bankston private easement area. If a developer desired, they could use a deviated route using the criteria mentioned above. However, this deviation was not recommended by the City Consultants, because it resulted in a higher ecological impact and potentially expensive condemnation procedures. 

How is the City Paying for this expensive infrastructure?

Infrastructure such as roads, trails, parks, water, sewer, electrical, cable, fiber, gas, and stormwater are all conveyed through public rights of ways (ROW). Municipalities like King City use public right of ways to convey infrastructure and provide services to our residents. All public roads are built/contained within a designated public right of way (ROW), these roads and ROWs are used for any number of services from simple infrastructure mentioned above to emergency services, transit, freight, bicycle pathways, postal services, etc. These ROWs and road networks create the backbone frameworks our cities are built on.

All this projected infrastructure and these services cost money to build and maintain. The city requires the developer to pay for roads and infrastructure servicing their development. However, the city cannot make a developer pay for improvements beyond their own impacts without a capital improvement plan, such as a TSP or Master Plan. So, City’s create plans that identify all the capital improvements they will need to properly serve the community. Once the plans are complete the City can develop a finance plan for the community resources/attributes the community desires and charge developers for the additional offsite improvements or amenities by establishing System Development Charges. Developers can choose to build the community amenities themselves and receive SDC credits, or they can simply pay the SDC fee, and the City will use those funds to develop the amenities identified in the plans.

SDCs are calculated using the total projected costs of the infrastructure divided by the projected residential units or Equivalent Dwelling Units (EDU). King City also uses a total floor area equation to produce a sliding scale to encourage equitable development and provide a wider range of housing types and opportunities.

Ultimately, SDCs are intended to pay for the projected amenities and capital assets so Taxpayers and current residents are not burdened with the cost of new development.
