Evaluation Factors
Adopted June 26, 2001
1.
Maintain or Improve Transportation Performance
1.1 Improve travel
times
- Morning, midday
and evening travel time for transit, autos and trucks to key locations
via I-5
- Morning, midday
and evening travel time for transit, autos and trucks from key locations
to I-5
1.2 Maintain
or reduce congestion
- Percentage of
highway lane miles in study area exceeding capacity (level of service
“F”)
- Percentage of
arterial lane miles in study area exceeding capacity (level of service
“F”)
- Study-area total
rush hours delay (for non-transit modes)
1.3 Promote transportation
choices
- Number and percentage
of trips by carpool, transit, bicycles and pedestrians
- Number and percent
of rush hour trips from downtown Vancouver and downtown Portland by
carpool, transit, bicycles and pedestrians
- Number of people
able to cross the Columbia River during rush hour (all modes)
- Change in vehicles
miles traveled (VMT) and VMT per capita Number of people able to cross
the Columbia River during rush hour (all modes)
1.4 Enhance public
safety
- Change in number
of traffic conflict points—difficult merges, for example
- Impacts on emergency
vehicle access
- Impacts on incident
management access
- Bridge height
encroachment into Pearson Airpark flight path
1.5 Improve travel
reliability
- Total exclusive
right-of-way by mode
- Duration of “rush
hour” congestion
- Dollar cost of
bridge lift delays for transit, autos and trucks
1.6 Minimize
impacts on other highways and streets
- Change in “rush
hour” traffic (autos and trucks) on highways and streets adjacent
to study area
2. Support Trade
and Freight Movement and the Regional Economy
2.1 Improve strength
of regional industrial areas
- “Rush hour” and
non-”rush hour” travel time for autos and trucks from key locations
to I-5
- Percentage of
truck route lane miles over capacity during rush hours
2.2 Increase
regional business savings
- Daily value of
reduced time spent in traffic by trucks and rail
2.3 Minimize
impacts to water navigation
- Qualitative measure
based on need to negotiate bridge piers
- Frequency of
bridge lifts
2.4 Reduce freight
delay
- Daily hours of
delay for trucks
3. Maintain or
Enhance Quality of Life
3.1 Reduce spillover
traffic into neighborhoods
- Traffic volumes
(autos and trucks) on selected roads
3.2 Support adopted
city of Portland and Vancouver plans (local/neighborhood livability
and transportation goals)
- Measures to be
determined in consultation with City staff
3.3 Avoid or
minimize noise impacts
3.4 Avoid or
Minimize right-of-way needs and displacements
- Acres of additional
right-of-way required
- Number of displaced
households, people, businesses acres of additional right-of-way required
3.5 Minimize
average commute length & time (representing time spent away from family)
- Average work
trip length
- Average work
trip time
3.6 Maximize
capacity (untapped capacity)
- Average vehicle
occupancy
3.7 Roadway Congestion
(see 1.2 above)
3.8 Increase
annual transit ridership per capita
- Annualized daily
transit boardings per capita
3.9 Minimize
Time time cost of travel (by mode)
- Weighted average
cost of travel
3.10 A general
quality of life indicator
4.
Avoid and Minimize Impacts to the Environment
Note – Where appropriate,
these environmental impacts will include measures of both quantity AND
quality of affected resources
4.1 Avoid or
minimize air quality impacts
- Production of
standard pollutants in study area
4.2 Avoid or
minimize impacts to natural resources
- Impacts to water
quality and quantity
- Impacts to fish
(including migration barriers and habitat) , wildlife, and sensitive,
threatened and endangered species and their habitats
- Impacts to wetlands
(acres, type, quality) and riparian areas (including buffers)
4.3 Avoid or
minimize impacts to historic, cultural, and institutional resources
(including neighborhood cultural resources – e.g. community colleges,
schools, libraries, etc.)
- Property acquisitions
and encroachments
- Change in access
- Visual impacts
- Noise impacts
- Vibration impacts
- Change in context
or use
4.4 Avoid or
minimize environmental impacts
- Geologic impacts
- Hydraulic impacts
- Hazardous materials
impacts
- Energy Consumption
/ Efficiency
5.
Support Regional Land Use Plans
5.1 Support growth
patterns identified in Clark Co. Comprehensive Plan and Metro 2040 Growth
Concept
- Mixed use development
in downtown Vancouver, downtown Portland, and regional centers
- Percentage of
population/employment forecasts achieved by subarea
- Average home
to work trip distance
6.
Distribute Benefits, Costs, and Impacts Equitably
6.1 Distribute
benefits equitably
- Impacts to be
measured by income level and minority status as appropriate
6.2 Distribute
costs equitably
- Impacts to be
measured by income level and minority status as appropriate
6.3 Distribute
impacts equitably
- Impacts to be
measured by income level and minority status as appropriate
7.
Evaluate Costs
7.1 Evaluate
project capital and operating costs
- Estimates of
public sector capital costs
- Estimates of
public sector operating costs
7.2 Evaluate
personal and business operating costs
- Estimates of
personal operating costs
- Estimates of
business operating costs
