Powers said that after the parking area is realigned to make it more efficient, the parking would be adequate for about 95 percent of the year — all but the busiest days of summer.
In terms of procedure, the NRA board must approve the plan before it can proceed.
If accepted as expected, the NRA and municipal planning officials would create a Request for Proposals, which would go out to private developers.
The developers would not have to follow the Union plan, but NRA Chairman James Shanley and Powers said that because so much thought had been put into this plan, a developer would likely want to pursue the basics of what has been proposed.
Shanley said it would be “months” before an RFP would be ready to circulate but that he is pleased with the direction the project is taking.
NRA officials say that a developer would buy land that related only to the footprint of the two buildings; all green space and parking area would remain in the possession of the city.
Shanley has said that private development of the two commercial buildings is essential to generate the money to pay for the addition of green space and to sustain it once it is completed.
