Definitions

•VMT: Vehicle Miles Traveled
•LOS: Level of Service. amount of congestion experienced at any given time
•TDM: Transportation Demand Management. An array of strategies designed
to broadly shift transportation away from single-occupancy vehicles.
•PM Peak Hour Trips: # vehicles that come and go from a given location
during the evening rush hour.
Existing Regulatory Framework
3
•Current Traffic Overlay District combines both these two, often distinct, processes
•Simple, but lacks flexibility
Transportation Regulation
Impact on Public
(assessment of delays,
safety, and queuing on
adjacent infrastructure)
Site
Configuration
(Site Plan
Review)
•Citywide Level of Service D applies to all development.
•Traffic Overlay District sets a hard cap on the number of vehicles
allowed to come and go from a parcel (trips) during the PM peak hour.
Key Goals in Changing Transportation Regulation
4
Planning Commission
feedback and
discussion on goals
•Match the level of requirements to the size of the
project.
•Direct private investment in towards meeting city
transportation goals.
•Do so in areas that the City has identified as ready
for development, using tools that the City is already
encouraging.
•Work towards CAP goals of reducing VMT and
enhancing equity.
Components Of A Better Regulatory Framework
5
1.Traffic impact fees remain in place for all vehicle trips.
2.Create a differing LOS requirement depending on geographic area of city.
3.Right-size the scale of review needed to the scale of project.
4.Create a TDM program with a menu of options for achieving a shift away from
single-occupancy vehicles.
6
Component 1: Traffic Impact Fees
•Retain existing Traffic Impact Fees for new development.
•Fees are assessed based on PM peak hour trips.
•Fund projects identified under CIP.
•Many are bike/ped improvements or within City Center.
7
Component 2: LOS & Congestion
Prelim Tier Corridors for
congestion analysis
•Replace the Traffic Overlay District with
street classification.
•Allows for different levels of congestion
tolerance in different places.
•Roadway tiers will guide analysis of
congestion and capacity, and inform
level of traffic mitigation needed for
each project.
8
Component 3: Right-Size Review with Project Size
•Sort all projects into a category scaled to traffic
impact.
•Small
•No additional TDM over LDR minimums
•No traffic study required
•Simplify trip calculation
•Standard
•Required to reduce total site trips by 5% from
proposed new total
•No traffic study required
•Large
•Required to reduce total site trips by 14% from
proposed new total
•Traffic study required
Example –
A large generator of new traffic will
have a greater number of trips to
remove
A use with 25 trips adding 75 trips for
100 total vehicle trips must achieve
86 trips through TDM
9
Component 4:
Create a Menu of TDM Options
Example TDM Options
•Encourage reduction of vehicle
trips through use of TDM policies.
•Vetted during Site Plan review.
•Gives applicants greater choice in
determining the best option for
their site.
•Streamlined with existing site
requirements for streetscape; bike
parking.PhysicalPreferential parking locations for car pooling or other high-occupancy
vehicles
Sheltered bike parking
Bus stop with shelter
On-site carsharing
Fleet of bicycles or Bikeshare on-site
Cargo/ ebike-specific bike parking spaces
Misc. Marketing/information program
Membership in a Transportation Management Association (TMA)
Special Options For Large Developments (tentative)Financial/ OperationalTransit subsidies/discounts
Car sharing membership or other Shared Mobility membership
Parking pricing or cash-out
Flextime to avoid typical commuter peaks
Telecommuting (1 or more days off-site); Compressed work weed (5 days-
> 4 days)
Participation in guaranteed ride home program
On-site childcare

Transportation Demand Management Process
Steps:
1.Specify land use type
a. Look up land use in ITE land use codes and currently
permitted trips
2.Specify the size of the development proposal (number of
units, gross floor area, etc.)
3.Determine net change in peak hour trips
a.From zero to some trips
b.From some trips to more trip
4.Determine any mitigation credit for proximity to transit.
5.Apply TDM policies to achieve required mitigation and/or
reduce impact fees.
Example
A store adds 10,000 more square
feet to an existing 50,000 square
foot store.
This would generate enough trips
to be a “standard” development
proposal for the purposes of
evaluating the change in the trips
and the impact on the network.
11
Transit Overlay
•Proximity to transit
counts towards trip
mitigation.
•Buffers show straight-line
distance to transit
services (green)
o ¼ mile (Blue)
o ½ mile (Red)
12
Transportation Management Plans (TMPs)
•All proposed projects would require a Transportation Management Plan
•Worksheet that summarizes and analyzes traffic impact of development.
•TMPs would require:
•A land use description
•Summary of multimodal infrastructure adjacent to site
•Number of average daily trips to and from the site
•The travel mode of the trips to and from the site
•How they will meet TDM requirements
•Inspection for Certificate of Occupancy would confirm physical TDM actions.
•Basis for future inspections of TDM compliance.
13
Questions For The Commission
Staff are working on regulatory language that will be brought to the Planning Commission in the next few months.
•Do we have a broad enough TDM menu of options?
•Should we restrict certain policies to certain sizes or types of development?
•Are there other activities and infrastructure that should receive credit for mitigation?
•Are we giving too much or too little credit for proximity to transit?
•Should TDM policies be optional or required?
