Developers Olmsted Green and Stony Brook, LLC plan to erect hundreds of homes and apartments, a supermarket, recreation center, nursing care facility and job-training center on the land.

The proposal met with some resistance.

The city originally planned to build a high school on 15 acres of the site. But there is no state money on the horizon for school construction, and Mayor Thomas Menino recently waived the city’s right to the state-owned land.

City Councilor Charles Yancey, whose district includes the site, objected to the move.

“We’re facing a shortage of high school seats,” he said. “We have some children attending classes in basements which weren’t designed for classes. I don’t know where else we’ll find 15 acres of land to build a new high school. I think the children were cancelled out of the equation. The mayor has given up some prime real estate.”

Menino could not be reached for comment before the Banner’s press deadline.

Developers expect to break ground on the housing by the end of the year. The development is really two developments, with 20 acres going to Stony Brook and 35 to Olmsted Green.

The Stony Brook team is led by ministers from the Christian Urban Economic Partners. The team plans to build 200 family homes, retail space, and 60 apartments for elderly people.

Of the family homes, 70 percent would be below market rate, for families earning between $40,000 and $80,000 a year.

The Greater Boston Interfaith Organization, one of the partners in Stony Brook, raised $6.5 million from parishioners to use as no-interest loans to reduce the cost of construction, which in turn lowers the sale price on the homes. Some of the units will be for homeless families, courtesy of the Pine Street Inn.

Like the Stony Brook plan, the Olmsted Green project also calls for hundreds of units of housing, which will bring some desperately needed relief to the demand-heavy Boston real estate market.

The plan calls for 300 new units of housing, a nursing care facility, an affordable recreation center open to the community at large and a job training facility also open to the community at large.

Almost half of the units would be market rate. The rest would be below market, but developer Kirk Sykes, a consultant and principal stakeholder for the project, could not say exactly what level of affordability they will have.

“The [affordable] half are affordable to the income levels of people within three miles of the site,” said Sykes.

Sykes indicated that the units would be affordable to many residents of nearby Wellington Hill, a neighborhood with a large population of two-earner black households.

He said that low-down payment mortgages would be offered through the Access Capital Company and Fannie Mae, the national low-income mortgage company.

“We will also work with low credit scores of 600,” he said.

The Olmsted group is a collaboration between the Lena Park Community Development Corporation and New Boston Development Partners, which is owned by the politically well-connected Jerome Rappaport.

Lena Park chose New Boston to partner with it after whittling down a field of 18 applicants, said Sykes.

“It sounds like the big white developer came and found himself some black people,” said Sykes. “But it’s kind of the opposite. The community partner chose a developer who could make sure the capital structure got completed.”

Governor Mitt Romney, who pledged to double yearly housing starts by the end of his term, gave his blessing to the plan.
