Here's a look at the seven student housing proposals.

Capstone Development Corp. and Jim Campbell

• Who: Local developer, Jim Campbell is partnering with the Birmingham, Ala.-based company that specializes in student housing. Capstone has won awards for its Taylor Place students apartments at Arizona State University's downtown campus.

• The project: A mixed-use student housing development with 700 beds on one acre at the former Greyhound property, next to the Rialto Theatre on East Congress Street and another site across Congress next to the railroad tracks. The plan would include a parking garage, which is now being built by the city, and more than 25,000 square feet of commercial space on both sides of the street. The site next to the Rialto could include 550 beds for student housing, and the site next to the railroad tracks could see between 70 and 170 beds, depending on whether rooms are designated for graduate students. A streetcar stop would be next to the site.

Peach Properties

• Who: The local property management and development company owns and manages several properties downtown and in central Tucson.

• The project: A 320-bed complex with 18,000 square feet of street-level retail on a site along the streetcar line on East Broadway. The site, bounded South Fourth and South Herbert avenues, would include a seven-story building that would not be as tall as it comes closer to the neighborhood to the south, Ron Schwabe said. The site would also include on-site parking in a garage, he said.

Stellar Cos.

• Who: A local effort owned by developers Scott Stiteler and Scott Cummings. Majority partner Stiteler owns the block surrounding the Rialto Theatre, and an adjacent block on Congress. He also owns the former Martin Luther King Jr. housing project, which has been turned into a housing and retail development.

• The project: The project would be located on the site of the former Corbett lumber yard, north of the railroad tracks between North Sixth Avenue, North Fifth Avenue, East Seventh Street, East Eighth Street. Stiteler said the property is 140,000 square feet, but the plans for student housing are undefined right now because the city is in the process of acquiring part of the project through eminent domain for the extension of Barraza Aviation Parkway and for a future maintenance facility for the streetcar. Stiteler said it's unclear what part of the site will be left for student housing, but said it still makes sense, especially when combined with his other downtown properties.

Concord Eastridge and Bourn Cos.

• Who: Scottsdale-based Concord Eastridge worked on a 13-acre master plan development at ASU, but the plan was shelved when the state budget crisis began. Their UA proposal is a joint venture with Tucson's Bourn. Other local partners include Rob Paulus Architects and Tofel Construction.

• The project: The group wants to redevelop La Placita Village, a colorfully painted office and retail center owned by Bourn and located along the proposed streetcar route at Broadway and South Church Avenue. Financing is in place for a plan that calls for 540 beds, parking, retail and academic spaces, said Concord Eastridge CEO Susan Eastridge.

American Campus Communities

• Who: The Austin-based student-housing developer manages the Entrada Real student apartment complex at University Boulevard and Stone Avenue. It also has done four ASU projects.

• The project: The company has been buying up property north of the UA campus on Drachman and Mabel streets, but the company's proposal has not yet been made public.

Clark Realty Capital and Duxbury Financial LLC

• Who: The East Coast multifamily development partnership is currently building a mixed-use development of student apartments and retail space at University of Maryland-College Park.

• The project: Information has not been made public.

Campus Acquisitions LLC

• Who: UA alum Mike Noonan, a developer from Cave Creek, partnered with this Chicago-based firm.

• The project: A plan to build a apartments for 300 students at North Euclid Avenue and East Fourth Street, near the UA main gate and along the proposed streetcar line, stalled in the city's rezoning process last year.
