Background
— Our WSP/Fehr and Peers team was selected to undertake the regional transportation study to accomplish two primary goals:— quantify and monetize the impact of warehousing and logistics
development on the freeway system in Riverside County
— Establish the framework for a logistics development impact fee
Study participants: Study partners:
7
Study Approach
— Forecast logistics growth
— Forecast truck trips— Identify deficiencies— Attribute
deficiencies to new logistics development
— Estimate project costs
— Compute fee amount
8
Unique Challenges
— Establish a clear definition of logistics developments, trucks and trip generation
— Avoid conflicts with existing regional transportation impact fee programs— Focus the study on the freeway
system
— Differentiating impacts— Other regional development
impacts
— Pass through truck trips
— Perceptions vs. reality

Defining Warehousing and Logistics
— Available source data often aggregates land uses that could be considered warehousing or logistics related.
— We will seek to remain consistent with NAICS definitions used as the basis for SCAG SED forecasts
Industry Code Brief Description
31-33(Manufacturing)
Establishments engaged in the mechanical, physical, or chemical transformation of materials, substances, or components into newproducts. Assembling of component parts of manufactured products is considered manufacturing, except in cases where theactivity is appropriately classified as Construction. (Example: Food Manufacturing, Textile Product Mills, Apparel Manufacturing,Wood Product Manufacturing, Chemical Manufacturing.)
42 (Wholesale Trade)
Establishments engaged in wholesaling merchandise, generally without transformation, and rendering services incidental to thesale of merchandise. Includes the outputs of agriculture, mining, manufacturing, and certain information industries, such aspublishing. (Example: Furniture and Home Furnishing Merchant Wholesalers, Household Appliances and Electrical and ElectronicGoods Merchant Wholesalers.)
48-49(Transportation &
Warehousing)
Industries providing transportation of passengers and cargo, warehousing and storage for goods, scenic and sightseeingtransportation, and support activities related to modes of transportation. Establishments in these industries use transportationequipment or transportation related facilities as a productive asset. Modes of transportation include air, rail, water, road, andpipeline. (Example: Freight Trucking Companies, Warehousing and Storage, Couriers and Delivery Services.)

Defining Warehousing and Logistics
— SCAG SED forecasts are developed based on employees, however, there is a preference to administer impact fees using building floor area
— Various trip generationrates will be referencedto interpolate buildingfloor area based onemployee growthand types of development

Defining Trucks
— Both SCAG and California statewide models include multiple truck classifications
— Study will remain consistent with SCAG model structure, specifically medium duty and heavy duty truck classifications (light duty is primarily pick up trucks)
12
Avoid conflicts with existing programs
— Existing WRCOG TUMF and CVAG TUMF address cumulative regional impacts of all development on arterial highway system
— Study will focus specifically on freeway system impacts and mitigation needs
13
Differentiating impacts
— Riverside County is a contiguous part of the Southern California region adjoining Los Angeles, Orange, San Bernardino, San Diego and Imperial Counties, as well as the State of Arizona
— The study must distinguish only the truck tripsattributable to development in Riverside County

14
Differentiating impacts
— Trucks represents only a limited portion of the total traffic in the freeway system— Truck traffic varies from about 5% to almost 40% of total traffic,
depending on the route and location
— The model will be used to estimate the portion of traffic, including trucks, associated with growth in only warehousing and logistics development

Differentiating impacts
— Many truck trips in Riverside County, especially Heavy Duty Trucks, have an origin or destination outside of Riverside County— Only the portion attributable to
development within Riverside County can be assessed a fee
— Model and Streetlight® O-D datawill be compared to distinguish theshare of truck trips attributable todevelopment in Riverside County from pass-thru trips

Perceptions vs. Reality
— Perception: Growth in warehousing and logistics uses in Riverside County are resulting in significant increase in heavy truck trips
— Reality: the growth in heavy duty trucks is more likely attributable to external development and economic influence (i.e. they are pass by trips). Development in Riverside County seems to generate proportionally higher shares of medium duty truck trips

17
Perceptions vs. Reality
— Perception: The growth in trucks is resulting in notable impacts to traffic on area freeways
— Reality: While there is no doubt growth in trucks is contributing to area traffic impacts, it is likely that when other traffic growth and external truck trips are factored out, the portion of impact attributable to trucks from internal development will be relatively small. — Furthermore, CA law requires impact fee revenues to be expended
promptly, and therefore revenues generated may not be sufficient to support major freeway investments

Study Progress
— Study is about 50% complete with completion anticipated mid summer, 2018
