Concurrency:
“[L]ocal jurisdictions must adopt and enforce ordinances which prohibit development approval if the development causes the level of service on a locally owned transportation facility to decline below the standards adopted in the transportation
element of the comprehensive plan, unless transportation improvements or strategies to
accommodate the impacts of development are made concurrent with the development.”
RCW 36.70A.070(6)(b)
![Page 3: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/3.jpg)
Local Discretion
• Timing– What part of the development process?
• Level of Service measurement– What transportation methods are measured?– What facilities matter?
• Level of Service standard– How much delay is acceptable?
• Transportation Improvements– Turn lanes? Buses?
![Page 4: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/4.jpg)
Funding Options
• SEPA (RCW 43.21C)– Can also stop development– Early in the development process
• Transportation Impact Fees (RCW 39.92)– Must be based on a six-year plan
• System Improvement Fees (RCW 82.02)– Capital facility plan– “Public streets and roads”
![Page 5: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/5.jpg)
Concurrency Fee
• Note that there is NO “Concurrency Fee”
• It is considered a “voluntary contribution” by a developer
• There is a concern (because of 82.02.020) that these contributions are not always legally allowed
![Page 6: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/6.jpg)
“New” Key Phrases
• “Reasonably necessary as a direct result of the proposed development” RCW 39.92.040, 82.02.020
• “Reasonably related” and a “proportionate share” RCW 82.02.050
• “Mitigate significant adverse impacts” and “reasonable and capable of being accomplished” RCW 43.21C.060
![Page 7: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/7.jpg)
SEPA / System Improvements
• SEPA mitigation for the development’s impact upon others in the existing environment
• System improvements are for benefit of the jurisdiction and all new development
![Page 8: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/8.jpg)
Three Prongs, Three Fees
• Concurrency Decisions– What to measure– What to accept– How to improve
• Fees– SEPA– Transportation Impact Fees– System Improvements

Concurrency Objectives
• “Everyone” agrees on the basic goal of concurrency:
“Ensure that public infrastructure supports development as it occurs”
• But this goal supports many competing objectives
![Page 11: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/11.jpg)
Concurrency Objectives
• Primary Objectives:– Control timing of development
– Support transportation system funding
– Focus development in desired geographic areas
– Provide financial tool to focus that development
![Page 12: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/12.jpg)
Concurrency Objectives
• Multi-Modal Objectives– Channel development to increase system
efficiency
– Support TDM strategies
– Expand travel options through development incentives
![Page 13: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/13.jpg)
Concurrency Objectives
• Regional and Local Objectives
– Local control
– Regional system performance
![Page 14: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/14.jpg)
Concurrency Objectives
• Secondary objectives*
– Limit the cost of the concurrency process• To the private sector• To the public sector
– A transparent process to the public– A credible process with the pubic
* Not issues of “outcome” but factors in the selection of the “best” process
![Page 15: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/15.jpg)

Evaluation Criteria
• “Best” approach is a function of the relative value you place on achieving different objectives
• Project will describe strengths / weaknesses of different approaches for ~13 criteria– Some criteria are unimportant for some
approaches
![Page 17: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/17.jpg)

![Page 20: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/20.jpg)
Evaluation Criteria
• Versatile (the approach benefits different development conditions)– Urban– Suburban– Rural
![Page 21: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/21.jpg)
Alternative Approaches to Concurrency
![Page 22: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/22.jpg)
Alternatives
• We are still inventing / refining alternatives
• We are open to suggestions / ideas / approaches
• The following are ways we are categorizing alternatives
![Page 23: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/23.jpg)
Alternatives
• Multiple ways to approach concurrency
– Degree of local/regional control
– Measuring plans, facility performance, or a combination
– Regulating behavior with/without incentives
![Page 24: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/24.jpg)
Category Strategy Continuum
Example Alternatives
ScaleLocal
Regional
1) Regional targets set; local jurisdictions meet them. 2) Locals set own standards
Measure
Infrastructure
Performance
1) Design MM capacity in terms of infrastructure; individual choice determines level of congestion.2) Setting and meeting targets for time, congestion, proximity, hours of service3) Targets are set as average VMT per person in the jurisdiction
System
Regulation
Incentive
1) Area that exceeds concurrency standard requires double impact fees. Areas in exclusion zone pay no impact fees2) Area that exceeds concurrency standard may not develop
![Page 25: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/25.jpg)
Measurements
• Plan deployment– Infrastructure construction based
– Define a desired set of infrastructure– Set a proportion that must be completed for a
given level of trip generation– Delay new construction until funding permits
that level of infrastructure completion
![Page 26: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/26.jpg)
Measurements
• Facility Performance– Transportation system performance criteria are
selected• Use (volume) and/or delay
• Vehicles and/or people
– Improvements must be made to the system if performance falls below standard
– No limit on what improvements are required• But they must result in meeting the performance
criteria
![Page 27: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/27.jpg)
Degree of Local/Regional Control
• Current systems are aimed at local control– Matches where land use decision making occurs– Can result in adverse regional effects
• A more regional system might be better for regional, multi-modal outcomes
• Could be a two tiered system– Nice upside – but may require legal change
![Page 28: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/28.jpg)
Regulations and Incentives
• Current law is written as regulation:– Can issue develop permit only if LOS is met
• Up / down decision
– Creates artificial boundary conditions• Difficult to set boundaries
– Because it is hard to estimate the effects of external impacts
– Because it is hard to predict future political decisions
– Often hard to change adopted standards as conditions change
![Page 29: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/29.jpg)
Regulations and Incentives
• Incentive system might produce more politically acceptable results– e.g., impact fees would go up in areas where
development is less desirable
– Other mechanisms might be adopted to shift the incentives for building in low density areas with poor alternatives to SOVs
![Page 30: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/30.jpg)
Regulations and Incentives
• Incentive system is likely to require legal changes– May conflict with current law on impact fees
(82.02.020) because of the inability to charge two separate transportation fees
![Page 31: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/31.jpg)
Importance of Measurement Units
• Previous studies point out:
What gets measured is what gets addressed
• So: the measurement unit drives the outcome of the concurrency process
![Page 32: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/32.jpg)
Measurement Units
• Are measurements “targets” or “absolutes?”– V/C ratios
• to be directly measured and indirectly estimates
• means the outcome is roadway construction
– VMT measures (e.g., VMT per person)• Used as an incentive system input
• Less objective (less direct measurement)
– People and/or vehicles
![Page 33: Multi-Modal Concurrency](https://reader033.fdocuments.net/reader033/viewer/2022051001/568147f1550346895db52869/html5/thumbnails/33.jpg)
Measurement Units
– Existence of infrastructure• Lanes to be built
• Park and ride spaces
• Existence of multiple entrances to state roadway
• Existence of roadway
– Existence of services• Revenue hours of service
• Seat capacity passing a screenline

Measurement Unit
• Performance indicators– LOS– Travel time– Delay– Mode split
