Members of the Santa Cruz County community are proposing a realistic, effective and affordable set of projects from the Unified Corridors Study called Scenario R. Scenario R provides congestion relief and public transit options on Hwy 1, Soquel/Freedom and the Coastal Corridor for $423M less capital ($1,154M vs $731M) and about half the annual operating expense ($30M vs. $16M). Using Measure D, Self-Help funds and conservative assumptions on federal and state grants, Scenario R can be implemented sooner, more flexibly and realistically with the resources under the RTC’s control or reasonably available.

The funding potential from Scenario B is used for both the Staff Preferred Scenario and Scenario “R”ealistic.
Funding potential of $13,400 is applied to the additional auxiliary lanes for Staff's preferred scenario in order to balance total Funding Potential of $455,000,000 based on RTP, State and Federal sources.
The Funding Potential of $10,200,000 from Scenario B is used for both Scenarios shown.
Funding potential for BRT lite ranges from $18,100,000 in Scenario A to $37,000,000 in Scenario C.
The RTC Staff Preferred Scenario includes intersection improvements for bikes and pedestrians but NOT for autos in Table 52 (UCS p150, Nov 2018). However, capital costs for these projects are represented as a single line item in Table 39 (UCS, p105, Nov 2018). The combined price is used in absence of another figure.
Cost estimate from Alta Planning + Design's "Proposed Modifications to the UCS Analysis Methods" is used. The Funding Potential includes Measure D and some additional State or Federal funds to balance total Funding Potential at $455,000,000. The cost of constructing a trail with BRT on corridor is considerably lower because it assumes a combined roadway for bus, bikes and other wheeled vehicles and a narrower trail for pedestrian access alongside.
A cost of $20 million was estimated in the attachment "Bridge Replacement and Rehabilitation", Dec. 3, 2015 RTC meeting, attachment 3-B.
From the UCS, the cost for an electrified rail system that utilizes electrical multiple unit vehicles is estimated to cost a total of $549.5 million.
Approximate cost to repair the entire corridor for freight use.

For RTC Staff Preferred Scenario with rail transit, costs are for electric units. Funding potential for rail transit is assumed to be at parity with bus transit.
