Metropolitan
Transportation Plan Executive Summary Appendices |
Between 1997 and 2017 Clark County jurisdictions have planned for transportation improvements in locations with existing or forecast future capacity problems. These anticipated improvements were taken into consideration in carrying out the Metropolitan Transportation Plan needs and air quality analysis.
The MTP transportation system is the existing transportation network with improvements made on those links where projects are programmed in the Transportation Improvement Program. In addition, improvement projects are included where regional need has been identified in the MTP development process for which there is strong regional commitment. Projects included in the MTP transportation system may eventually be programmed for funding by federal, state, Transportation Improvement Account (TIA) and/or local sources.
Assignment of forecast future year trips onto the MTP transportation network in the regional travel forecasting model reveals where there are likely to be deficiencies in the transportation system over the longer term. Locations where future traffic volumes exceed MTP system capacity require an analysis of remedial measures to solve these anticipated deficiencies and an analysis of financial feasibility.
The following list is of the major transportation improvements which have been incorporated into the MTP transportation network for Clark County. These listed projects were identified in the Metropolitan Transportation Plan needs analysis and included in the air quality conformity analysis as required by the federal Clean Air Act Amendments and Washington Clean Air Act. The 1998-2000 Transportation Improvement Program for Clark County is consistent with this list.

Projects listed above include both projects on the regional transportation system as well as projects off the regional system which have been included in the regional travel forecasting model network and have therefore been included in the regional air emissions analysis to meet the requirements of the federal Clean Air Act Amendments and Washington Clean Air Act.

In addition to the above listed projects, the RTP is supportive of maintenance, preservation, safety, pedestrian, bicycle, enhancement, Transportation System Management (TSM), Transportation Demand Management (TDM) and any other project for which a need has been demonstrated through the regional transportation planning process that will serve to enhance the efficiency and operation of the regional transportation system.
| Maintenance | |
| Maintenance work ensures a safe, reliable and efficient transportation system on a day to day basis with such activities as pothole filling, repair of damaged bridges, incident response, maximizing operational efficiency by signal timing, snow clearing, vegetation planting and clearing, drainage and fence maintenance and litter removal. The MTP supports regional system maintenance work identified by WSDOT and local agencies. | |
| Preservation | |
| Preservation projects ensure that investment in the regional transportation system is protected. Specific projects include repaving of highways, refurbishing rest areas and bridge rehabilitation. Needs and projects are identified by local agencies and WSDOT through such programs as the Highway Performance Monitoring System (HPMS), ISTEA-required Pavement Management System (PMS) and Bridge Management System (BMS). Clark County bridge needs are listed in Appendix B. | |
| Safety | |
| Needs identified through the ISTEA-required Safety Management System (SMS) and local analysis. Safety improvements can include intersection improvements and signalization. | |
| Pedestrian and Bicycle Mode | |
| Needs identified through state and local planning programs including
recommendations from the Clark County Bicycle Advisory Committee, GMA plans and the Clark
County Trails and Bikeway System Plan (December 1992; Clark County). Notable pedestrian and bicycle projects in Clark County include completion of the City of Vancouver’s Columbia River Waterfront Trail, the Discovery Trail, the Columbia River/Evergreen Highway Trail, Hazel Dell Avenue bike lanes and SE 164th Avenue bike lanes. Also of regional significance is improvement of pedestrian and bicycle facilities which will improve access to transit facilities. Bike racks are already provided on C-TRAN fixed-route buses and bike lockers are provided at C-TRAN Transit Centers and Park and Rides. The bike rack and locker program will continue. |
|
| Transportation System Management | |
| Potential TSM solutions are outlined in the State’s Statewide Multimodal Transportation Plan, System Plan Component as well as local Growth Management plans. They include projects to interconnect traffic signals, to optimize signal timing and to ramp meter certain interchange ramps on the interstate system. | |
| Transportation Demand Management | |
| Demand management activities are determined through the Commute Trip Reduction program ongoing in the Clark County region. | |
Should projects in the categories listed above require state or federal funding, they are brought forward to RTC as the region’s MPO to carry out a coordinated decision-making process whereby projects are prioritized and selected for funding. Regional level air quality conformity analysis is prepared by RTC and project level conformity analysis, where required, is prepared by RTC for local projects and by WSDOT for State projects.

Air Quality Conformity Statement
The Metropolitan Transportation Plan for Clark County is found to contribute to emission reductions and is found to be in conformity with the Federal Clean Air Act as amended in 1990 and the Washington Clean Air Act (chapter 70.94 RCW). The MTP does not adversely impact the existing SIP and is in conformity with it.
All regionally significant transportation improvement projects are included in the regional travel forecasting model for purposes of air quality conformity analysis. A brief description of air quality conformity analysis methodology and results table follows.
Air Quality Conformity Methodology and Results
The Southwest Washington Air Pollution Control Authority (SWAPCA) has developed, as supplements to the State Implementation Plan, two Maintenance Plans; 1) for Carbon Monoxide (CO), and 2) for Ozone (O3). Both Plans were submitted to the Environmental Protection Agency (EPA) for approval. The Environmental Protection Agency (EPA) approved the CO Maintenance Plan in October 1996, and approved the Ozone Maintenance Plan in April 1997. Mobile source strategies contained in the Maintenance Plans have been endorsed for implementation by the RTC Board of Directors (Resolution 02-96-04).
The MTP must comply with the mobile emissions budgets specified in the Maintenance Plans. The test is designed to prevent violation of the National Ambient Air Quality Standards (NAAQS); transportation emissions are not allowed to exceed levels relied upon in the Maintenance Plan demonstration. To ensure consistent assumptions, the same methodology used to develop mobile emissions budgets for the Maintenance Plans is used in the MTP air quality conformity process.
The air quality conformity analysis relies on travel data for three time periods (the AM 1-hour, the PM 2-hour, and the rest-of-the-day) and is based on use of emme/2, regional travel model software, and on use of Mobile 5ah to determine emissions rates as part of the emissions calculations. Input assumptions for Mobile 5ah were received from the Southwest Washington Air Pollution Control Authority (SWAPCA) and the Oregon State Department of Environmental Quality (ODEQ). Hot stabilized emissions are calculated for each link in the system.
Each of the emitted gases (Carbon Monoxide (CO), Hydrocarbons (HC) and Nitrogen Oxides (NOx), has several categories of emission that make up the all-day total; hot starts, cold starts, and hot stabilized emissions. In addition, HC emissions also include hot soaks (which occur at the end of a trip in the destination zone), and diurnal emissions (those which occur during the day as rising temperatures cause vehicles to produce emissions through evaporation). CO is calculated for winter conditions, and HC and NOx are computed for summer conditions. The emissions calculations includes emissions caused by intra-zonal trips (trips which begin and end in the same Transportation Analysis Zone (TAZ). All outputs were seasonally adjusted based on EPA/SWAPCA guidance.
