31.03.130 Transportation – Inventory and analysis.
(1) GMA Goals. Encourage efficient multimodal transportation systems such as trails that are based on regional priorities and coordinated with County and city comprehensive plans.
Ensure that those public facilities and services necessary to support development shall be adequate to serve the development at the time the development is available for occupancy and use without decreasing current service levels below locally established minimum standards.
(2) Definition. The transportation system is composed of air, water, and land transportation facilities and services, including highways and streets, paths, trails and sidewalks, transit, airports, and ports.
(3) Circulation System. The transportation and circulation system should function to serve the land use patterns established by the Comprehensive Plan. For example, rural areas should be served by a transportation system designed for rural uses while urban areas should be served by a circulation system designed to serve urban uses. The transportation system should also focus on connections, either between urban centers, such as from Port Angeles to Sequim, or Carlsborg to Sequim, or between different “modes” of travel, such as automobiles to public transit. Some parts of the circulation system in this area serve County-wide and State-wide interests, such as Highway 101, the Sequim Valley Airport, Olympic Discovery Trail, Old Olympic Highway, and boat launch/moorage facilities. It is imperative that the County-wide and State-wide interests are considered when making land use or facility decisions affecting these systems.
(4) Land Use Coordination. In the past, land use planning and transportation planning were not always coordinated. Developments were approved on roads without consideration to impacts on roads or better use of public transportation. Conversely, roads and highways were built in rural areas which encouraged conversion of rural areas into higher densities or commercial centers. The Clallam County Comprehensive Plan indicates that the transportation system should be consistent with the land use plan.
(5) Level of Service. Level of service standards are used to serve as a gauge to judge the performance of the transportation system. When land use assumptions are made based on expected population growth and traffic demand, transportation engineers determine whether the transportation system is capable of handling the increased demand by using these level of service (LOS) standards.
LOS standards are based on the average daily traffic (ADT) and characteristics of the area that the road serves (rural, suburban and urban). LOS standards indicate congestion or how free-flowing the traffic is. LOS standards do not indicate whether the road meets adopted County road (safety) standards.
The level of service established in the County-wide Comprehensive Plan for County roads, either in urban or rural areas is LOS “C.” Level of service for State highways is LOS “D” for urban areas and tourist corridors, and LOS “C” for rural highways. Figure 5 indicates that all County roads are currently operating at or above these standards.
The forecast of future traffic on County roads in this plan is based on two (2) methods: projected population growth and build-out potential based on land use designations. The forecast of traffic and the impact on adopted LOS standards is used to determine if the transportation system is capable of handling the demand. If the system is not capable of handling the demand, the comprehensive plan must identify how the system will be improved and financed, or the land use plan must be revised to ensure that the minimum “level of service” standards are met.
Figure 6 indicates that the system is designed to accommodate the projected land use plan for this region, with some exceptions that should be monitored. Table 2 in this section, however, indicates that the system is not designed to handle the estimated build-out. The following roads show failure to meet LOS standards based on the build-out analysis: West Sequim Bay Road, Sequim-Dungeness Way, and Old Olympic Highway. At what date they fail to meet LOS standards depends upon growth rates. As can be seen in the table, portions of Old Olympic Highway and Sequim-Dungeness Way are already operating at LOS “C.” This indicates that these road segments may fail to meet standards within a shorter period of time.

1. Current LOS is analyzed using the Highway Capacity Manual. 2. LOS is determined based on future build-out with two considerations: vacant parcels and proposed land use densities within the plan. 3. LOS 2000 and LOS 2010 is based on projected population growth rates, not land use densities or vacant parcels. 4. ADT – Average Daily Traffic. Most Recent Count is anywhere from 1985 to 1993. The ADT for population counts are based on projected population growth rates. |
(6) Road Standards. Level of service standards do not indicate that a County road meets minimum design standards. Design standards for County roads are set forth in RCW 35.83.030 and RCW 43.32.020. Those standards are as follows:
ADT |
Below 150 |
150 – 400 |

Based on these standards, Figure 7 indicates the County collectors and minor collectors with width deficiencies. As can be seen in this table, nearly all of the County roads in this region do not meet the adopted road width standards, even though they meet LOS standards.
Table 3 identifies segments of County roads which are 18 feet or less in width with over 125 average daily traffic (ADT). These roads do not meet minimum safety standards. The table also clearly outlines the discrepancy between using LOS standards and road width standards. For example, although Taylor Ranch Road is currently at LOS “A,” and is projected to be LOS “B,” it clearly is deficient in road width (only twelve (12) feet). LOS measures how free-flowing a roadway segment is, but fails to recognize whether the road meets minimum safety standards.

(7) Private Roads. The transportation system in the Sequim-Dungeness region also includes private streets and easements, often unimproved, designed to serve lots within short plats and surveys. A mechanism to upgrade these roads to land division and fire protection minimum standards should be in place to assist property owners developing property which does not directly abut a public street.
(8) Alternative Solutions. Solutions to transportation deficiencies may include incentives to change patterns of transportation behavior, such as car pooling rather than single occupancy vehicles, and enhancements to alternative modes of transportation that would be efficient and less costly to maintain, such as transit, bicycle lanes, and trails.
