DETROIT -- After more than three years of planning, the group charged with creating a viable regional transit system in Southeast Michigan unveiled its proposal Tuesday, including a tax request likely to be decided in the November election.

The plan includes a Detroit-to-Ann Arbor passenger rail, buses with dedicated lanes along three major corridors, express bus services to major regional destinations, a universal fare card and several other improvements to the Metro Detroit's currently disjointed and dysfunctional transit system.

But the $4.6 billion plan would raise property taxes.

The Regional Transit Authority of Southeast Michigan plans to propose a property tax of 1.2 mills on the Nov. 8 general election ballot in Macomb, Oakland, Washtenaw and Wayne counties.

The regional transit millage would add $1.20 in taxes for every $1,000 of taxable value in a property. The new tax would cost the owner of a $150,000 home $90 per year for 20 years starting in 2017.

"Southeast Michigan is the only major urban area in the country without a viable, coordinated public transit system," said Paul Hillegonds, RTA chairman, in a news release. "If we are going to be competitive in a (modern) global economy, developing a transit system that meets the needs of a changing world is absolutely essential.

"The plan being unveiled today will connect people with jobs, connect communities with one another and encourage economic development as well as providing greater independence for seniors and people with disabilities."

The plan includes the following:

Bus rapid transit routes on Woodward Avenue from Downtown Detroit to Pontiac, on Gratiot Avenue between Detroit and M-59, and on Michigan Avenue and Merriman Road between Detroit and Detroit Metropolitan Airport.

A bus rapid transit route on Washtenaw Avenue between downtown Ann Arbor and downtown Ypsilanti.

Regional commuter rail between downtown Ann Arbor and downtown Detroit.

"Cross-county" connector and commuter bus routes that would "provide seamless service across municipal and county lines."

Express service to Detroit Metropolitan Airport from Ann Arbor, Downtown Detroit and Macomb and Oakland Counties.

Improvements to paratransit service, initiated by request for seniors and the disabled.

The addition of a universal fare card that works on all transit systems in the region.

The existing bus lines of the Ann Arbor Area Transportation Authority, Detroit Department of Transportation, the DTC and SMART will all act as "the foundation of a new regional transit system," the RTA announced.

RTA officials said they held 124 meetings and spoke with around 5,000 Metro Detroiters as it developed the master plan

"Too many people have struggled for too long simply trying get to work, school, and appointments without a car," said Megan Owens, executive director of Transportation Riders United in a release. "The RTA heard and heeded the public outcry for a change. This plan is a great path towards ensuring everyone in our region can access the opportunities our communities offer."

Planners said the system would connect 310 schools, 23 colleges, 22 hospitals, 47 libraries and more than 100 grocery stores in the region.

The RTA estimates 67,844 jobs would be supported across the four counties, and would generate about $1 billion in growth of real personal income in Macomb County, $1.8 billion in Oakland County, $244 million in Washtenaw County, $1.25 billion in Detroit and $122 million in the rest of Wayne County.

The RTA was established in 2013 to coordinate the region's various, largely unconnected local transportation systems and to propose new transit infrastructure.

In 2014, the group decided to delay proposing a millage to support the effort until November 2016.

The RTA millage proposal is written as follows:

The proposal needs a majority of the combined votes in the region to pass.

The RTA is planning to hold a series of public meetings before its board votes July 21 on the plan to place the millage proposal on the ballot.
