After years of gathering public input to create a regional growth plan, Imagine Greater Tucson is seeking donations from the public to turn its attention to a transportation plan.

With a land use plan based on how residents here want the area to grow, IGT wants to create a long-term transportation plan to accompany expected future population growth and land use priorities, said Mike Holmes, the organization's executive director.

The fundraising effort would allow Imagine Greater Tucson to do "more workshops, more engagement in various areas of the county, and asking questions about how they’d like to see transportation take shape in our region," Holmes said.

The Imagine Greater Tucson budget of about $300,000 comes from federal transportation funds, plus private and corporate donations, Holmes said.

Now the organization has a goal of $100,000 in donations from the public to continue its work.

"We're turning around to the public and saying: here's the work that we've accomplished so far, and we'd really like to do more of it and we need your help," Holmes said.

There are already two other transportation plans in place for the region, a plan the Pima Association of Governments maintains as it doles out federal transportation dollars to regional governments, and a 20-year, voter-approved plan to spend $2 billion on regional roads, which the Regional Transportation Authority oversees.
