RTIF Fact Sheet 12-13

  • RTIF (Regional Transportation Impact Fee)

By 2030, the Solano Transportation Authority (STA) is projected to receive enough federal and state funding for seven new projects ($986M) to help accommodate the increasing demand for "regional mobility" in Solano County. Additional projects identified through other studies or by local cities and the county cannot compete for limited future funding, despite their local necessity for "regional" mobility.

Because of high projected growth in population and jobs, Solano County needs to be creative and opportunistic to find funding for new projects. One local option explored since 2008 is a Regional Transportation Impact Fee (RTIF) that can provide needed infrastructure improvements for local and regional projects in Solano County. The RTIF was subsequently approved on December 3, 2013 by the Solano County Board of Supervisors, as part of the Solano County Public Facility Fee Update. Upon recommendation by the STA Board, the County Board of Supervisors approved a total RTIF fee of $1,500 per dwelling unit equivalent.

***December, 2017 Update***

RTIF Annual Report for FY 2016-17

The RTIF Annual Report for Fiscal Year (FY) 2016-17 is included as Attachment A to this report.  In summary, a total of $1.421 million was collected for eligible RTIF projects in FY 2016-17 (after accounting for STA's two percent administrative fee to manage the program).  The RTIF revenue collected was an increase of a little more than $200,000 in comparison to last fiscal year which had $1.264 million collected.  Since the program began, a total of $4,443,190 has been collected with 84% of the funds have been obligated to the RTIF eligible projects.   

Currently, two of the seven RTIF Working Groups have completed construction of their initial project (as of June 30, 2017).  Three more working groups have projects under construction and two other working groups have projects in the project development phases:

1.     Working Group 1 - Jepson Parkway - 2 phases Under construction

2.     Working Group 2- Hwy 12 Church Road Environmental Documents - Completed

3.     Working Group 3- Benicia Bus Hub - Complete

4.     Working Group 4 - Green Valley Overpass - Under Construction

5.     Working Group 5- Midway Road Intersection Safety Improvements- In Design

6.     Working Group 6- Benicia Bus Hub - Complete

7.     Working Group 7- Vaca Valley Parkway and Mid Way Road- Under Construction


***October, 2016 Update*** 

The RTIF collection formally began on February 3, 2014. Each of the seven cities and the County participate in the selection of RTIF projects through seven RTIF Working Groups.The RTIF Annual Report for Fiscal Year (FY) 2015-16 can be found here. In summary, a total of $1,285,925 was collected for eligible RTIF projects in FY 2015-16 with a total of $3,109,866 collected since the program began in 2014. 

Five out of the seven RTIF Working Groups are advancing projects and have received RTIF allocations for accrued expenditures from FY 2015-16. These include the following projects:

• Working Group 1: Jepson Parkway Project - Right of Way Phases completed for phases in Fairfield and Vacaville and construction scheduled to begin in FY 2016-17.
• Working Group 2: SR 12/Church Road Intersection - environmental phase nearing completion
• Working Group 3: SR37/Redwood St/Fairground Dr. - environmentally cleared and preparing for design work subject to full funding availability
• Working Group 4: Green Valley Overcrossing- Under Construction
• Working Group 6: Benicia Industrial Park Transit Hub - Under Construction Currently, 91% ($2.759 million) of the total RTIF funds ($3.402 million) collected through FY 2015-16 have been allocated by the STA Board for RTIF eligible projects.


***October, 2014 Update***

The County began collecting the RTIF as part of the revised PFF on February 3, 2014.  Based on the RTIF Expenditure Plan developed by the STA, a total of 5% of the total RTIF revenue to be dedicated towards transit projects under Package 6- Express Bus Transit Centers and Train Stations and 5% is dedicated to Unincorporated County Roads under Package 7.  The remaining balance of the RTIF (90%) will be returned to each RTIF District from which it was generated. $89,671 was collected for RTIF projects for the 3rd quarter and $298,879 was collected in the 4th quarter of Fiscal Year (FY) 2013-14.  This brings the total RTIF collected to date at $382,574, predominately from the cities of Fairfield and Vacaville building permits, for eligible RTIF projects.

What is a Regional Transportation Impact Fee?

A transportation impact fee is established by a local or regional government (usually collected during issuance of the building permit) in connection with approval of a development project for purpose of defraying all or a portion of the cost of particular public facilities, in this case, transportation projects (e.g., roadway expansion, transit centers, interchanges, etc.). Regional Transportation Impact Fees (RTIF) are used in a variety of counties throughout the State of California to help fund transportation projects.


STA Regional Transportation Impact Fee (RTIF) AB1600 Nexus Report

The legal requirements for enactment of a transportation impact fee program are set forth in the California "Mitigation Fee Act", which was adopted in 1987 under AB 1600, and thus these fees are commonly referred to as "AB 1600" fees. An impact fee is not a tax or a special assessment so, by definition, a fee must be "reasonably related" to the cost of the facility or service provided by the local agency. The STA RTIF Nexus Report was adopted on July 11, 2013 by the STA Board for inclusion in the County of Solano's Public Facility Fee Update. The Nexus Report recommends how a potential fee program would relate fees collected to improvement selected projects.

Potential Revenue Options

  • Regional Measure 3 (RM3)


  • Express (High Occupancy Toll) Lanes

    The STA supports the concept of partnering throughout the Bay Area region to establish a regional High Occupancy Toll (HOT) Lanes or Express Lanes network in the Bay Area as a means to reduce traffic congestion and increase mobility with assurance that revenues collected for the use of Express Lanes are spent to improve operations and mobility in the corridor in which they originate.

    A High Occupancy Toll (HOT) or Express Lane, is a toll paid by single-occupant vehicles who wish to use lanes or entire roads that are designated for the use of High Occupancy Vehicles (HOVs, i.e.  carpools, vanpools and buses).  Tolls are collected by electronic toll collection systems.  The toll varies based on demand, called congestion pricing.  The tolls change throughout the day according to real-time traffic conditions to manage the number of cars in the lanes and keep them free of congestion, even during peak periods.

    Caltrans, MTC and STA partnered on the I-80 corridor with an HOV Lanes project between Red Top Road and Air Base Parkway.  These Lanes are being considered for conversion to Express Lanes through a “Rapid Delivery Design” approach to fit Express Lanes within existing right-of-way.  STA is also considering building new Express Lanes on I-80 from Air Base Parkway to I-505.  Constructing Express Lanes in Solano County provides an opportunity for construction of segments of these Lanes within 5 to 10 years.

  • P3 (Public-Private Partnership)

A Public Private Partnership (P3) is a partnership between a public agency and a private entity for the mutual benefit of both parties.

  • Vehicle Registration Fee (SB 83)

In 2009, the California State Legislature approved Senate Bill (SB) 83, which provides the option for a countywide transportation agency to place a Vehicle Registration Fee (VRF) before the voters. The VRF provides counties the opportunity to obtain a dedicated local funding source for transportation improvements that benefit or mitigate the automobile.

Results of a Public Opinion Poll for a potential SB 83 Expenditure Plan were presented at the STIA Board meeting on June 15, 2010.

The STIA Board recommended the STA develop an Expenditure Plan for a potential $10 vehicle registration fee assessed annually on each vehicle registered in Solano County. The Board directed staff to hold a series of outreach meetings to receive public input on the Expenditure Plan. The Plan will focus on the following three identified priorities:

Maintenance of Local Streets and Roads, Safe Routes to School, Senior and Disabled Mobility

The STA Board reviewed the Draft Expenditure Plan at its meeting on July 14, 2010, and received input from the public. The Board met again on August 5th to determine whether or not to place the measure on the November ballot. If approved by a majority of Solano County voters, the $10 fee would generate $3.2 million per year to directly support transportation as outlined in the VRF Expenditure Plan. After receiving public input, the STA Board on a split vote opted NOT to place the measure on the ballot. Thank you to all those who provided input into the development of the plan and public comment regarding the plan and the measure.

  • 5310 Senior/Disabled

FTA Section 5310 Elderly and (People with Disabilities) Disabled Transit

The purpose of the program is to provide capital grants for projects that meet the transportation needs of elderly persons and persons with disabilities where public mass transportation services are otherwise unavailable, insufficient or inappropriate.



  • SB 1 - Road Maintenance and Rehabilitation Account/Program

Roadway PavingIn early April 2017, the California Legislature passed and Governor Brown signed the Road Repair and Accountability Act of 2017 (SB1). The $5.24 billion/year funding package, which generates new revenues from various taxes and fees, is designed to repair and maintain our state highways and local roads, improve our trade corridors, and support public transit & active transportation. This bill provides the first significant, stable, and on-going increase in state transportation funding in more than two decades. 

Solano-Specific estimates from various funding categories mentioned below are highlighted in the hyper-linked text.

**Update 12/15/17**

SB1 Solano Priorities Fact Sheet 12-17Some of the new programs that were created as part of SB1 are competitive.  STA is working hard to position ourselves to compete for these funds.  The proposed I-80 Express Lanes, which would run from North Texas St in Fairfield to I-505 in Vacaville, is a candidate for the Congested Corridors program.  MTC and Caltrans have placed this project on their "tier 1" lists. Applications are due to the California Transportation Commission in January 2018.

An updated SB1 summary sheet has been created by STA to help inform the public of our priorities.   





**Update 7/21/2017**

 The California State Transportation Agency (CalSTA) and the Department of Transportation (Caltrans) today announced the fast tracking of "fix it first" construction work and increased road repairs across the state. Caltrans is able to jumpstart these road repairs thanks to the passage of the Road Repair and Accountability Act of 2017 (Senate Bill 1), recently passed by the Legislature and signed by the Governor. A complete list can be found here: SB1 Expedited Projects 

4 Solano projects were selected to be expedited for delivery this fiscal year.  The projects are:

  • I-505: $9 million project near the cities of Vacaville and Winters will resurface ten miles of Interstate 505 from Interstate 80 to the Yolo/Solano County Line.
  • SR113: $1.4M project will repair and resurface various sections of State Route 113 between Rio Vista and Dixon.
  • SR84 and SR220: $1.7 million project will place a chip seal on nearly 18 miles of State Routes 84 and 220 in Solano County.
  • I-80/SR29 Overcrossing: $19.1 million project will replace bridge to meet standard truck load capacity.

SB1 creates the Road Maintenance and Rehabilitation Account and the Road Maintenance and Rehabilitation Program which adds funds to already existing funding accounts. Programs funded by this account include:

  • State Transportation Improvement Program (STIP) - Stabilizes the program and pegs its growth to inflation.
  • Active Transportation Program - Adds approximately $100M annually to this program.
  • State Highway Operation and Protection Program (SHOPP) - Adds approximately $1.1B annually to his program, in addition to a one time infusion of $75M.
  • Local Streets and Roads (LS&R) apportionments - Adds approximately $1.1B annually to this program, in addition to a one time infusion of $75M.
  • Caltrans Bridge and Culvert - Used by Caltrans, adds $400M to this program.

SB1 Impacts on Solano CountySB1 provides additional funding to existing transit categories including:

  • STAF Revenue and Population Based - Adds $250M annually to this program
  • STAF Capital Revenue and Population Based - Adds $105M annually to this program
  • Transit and Intercity Rail - Adds $245M annually to this program, in addition to a one time infusion of $79M.
  • State-Supported Intercity Rail - Adds $19M annually to this program. Each of the state's three intercity rail corridors will receive a minimum of 25 percent of these funds.
  • Commuter Rail - Adds $19M annually to this program. Each of the state's five intercity rail corridors will receive a minimum of 20 percent of these funds through FY 2019-20. Commencing on July 1, 2020, the funds will be allocated based on guidelines and a distribution formula adopted by CalSTA.

SB1 also creates other new funding categories including:

  • Local Partnership Program (Self-Help Counties) - This is a new $200 million per year program. Bill states:
  • Funding from this program is "for counties that have sought and received voter approval of taxes or that have imposed fees, including uniform developer fees."
  • Funds are appropriated "for allocation to each eligible county and city in the county for road maintenance and rehabilitation purposes."
  • Solutions for Congested Corridors Program - This is a new $250 million per year program beginning FY 2017-18. Competitive. The California Transportation Commission (CTC), in consultation with Air Resources Board (ARB), shall adopt program guidelines. The Commission shall allocate no more than one-half of the funds available each year to projects nominated exclusively by the Department (Caltrans). Preference shall be given to corridor plans that demonstrate collaboration between the department and local or regional partners.
  • Trade Corridor Enhancement - SB 1 creates this new $300 million per year account to fund corridor based freight projects nominated by local agencies and the state.


  • STIP (State Transportation Improvement Program)

The STIP is a multi-year capital improvement program of transportation projects on and off the State Highway System, funded with revenues from the Transportation Investment Fund and other funding sources.  STIP programming generally occurs every two years.  The STIP is composed of two sub-elements:  the Regional Transportation Improvement Program (RTIP) and the Interregional Transportation Improvement Program (ITIP).  MTC adopted the Policies and Procedures for the 2010 RTIP on October 28, 2009.  The Policies and Procedures lay out project selection criteria, schedule, and application procedures for the 2010 RTIP.  As Solano County’s Congestion Management Agency (CMA), STA is responsible for developing Solano County’s program of STIP projects.  The final project list and supporting documentation was submitted to MTC in December 2009, for inclusion in the 2010 RTIP.  The 2010 RTIP was then submitted to the California Transportation Commission for inclusion in the STIP.

At the October 12, 2011 STA Board meeting, the STA Board approved the 2012 STIP funding recommendations, which included funding for the Jepson Parkway and Dixon's West B Street Undercrossing.  The STIP funding recommendations are detailed in the October 12, 2011 Board Staff Report.

The STA is committed to its local partners and to the completion of both the Jepson Parkway and the West B Street Undercrossing projects. By programming funds to these projects, STA will be fulfilling that commitment. In committing PPM funds, STA is also fulfilling its commitment to facilitating planning, programming, and project monitoring activities in Solano County.

  • SHOPP (State Highway Operations & Protection Program)

Caltrans SHOPP (State Highway Operations & Protection) Program provides funding for pavement rehabilitation, operations, and safety improvements on state highways and bridges. It is only used for maintenance, rather than expansion of state highways. Currently, there are eight SHOPP funded projects are under construction in Solano County; four on I-80, and one each on I-680, I-780, SR-29, and SR-113. Additionally, there are seven more projects in the design/environmental analysis phase. This amounts to a total investment of $56 million in state highway maintenance dollars flowing into our county.

***The September 2017 STATUS newsletter states that $101 million in SHOPP funds flowed into Solano County.  This is an error that accounted for $45M in the I-80/I-680/SR12 phase I project.  The actual total should read $56 million***

Major I-80 SHOPP Construction Projects:

  • Safety improvements from Vallejo to Vacaville ($3.8 million)
  • A bridge replacement and rehabilitation at Midway Road and Meridian Road ($5.5 million)

All three projects are expected to wrap up by winter 2018.

Other Major SHOPP Projects in Solano County:

  • Installing new crosswalks on SR-29 in Vallejo ($1.1 million)
  • SR-113 north of Creed Road ($3,000)
  • A new drainage system on I-680 at Marshview Road ($479,000)
  • I-780 Improvements at I-80 ($4.7 million)

Caltrans is also in the design/environmental review process for seven additional SHOPP funded projects in Solano County. I-80 is scheduled to receive 5 of these projects, two to be completed in 2019 and the other three in 2021. To be completed in 2019 on I-80 will be rehabilitation of the Dan Wilson Creek Bridge in Fairfield ($2.6 million), and median barrier replacement from west of the Gibson Canyon Creek Bridge in Vacaville to Curry Road in Dixon.

In 2021, Caltrans will complete scour mitigation at the Suisun Creek Bridge in Fairfield ($760,000), increase vertical clearance at six overcrossing structures from Magazine Street to Redwood Street in Vallejo ($16 million), and perform preventative maintenance on three separate bridges: I-80/SR-29 Separation Bridge in Vallejo, McCune Creek Bridge in Dixon, and Horse Creek Bridge in Vacaville (total cost $1.4 million). Also in the short term plans is a roundabout at the SR-12/SR-113 interchange ($4.6 million), to be completed in 2019, and replacing the Miner Slough Bridge on SR-84 north of Rio Vista in 2021 (cost TBD).
