With revenue expected from the Wal-Mart and Lowe’s proposed for Hooksett’s west side, the Hooksett Planning Board is hoping to speed up massive improvements to the already congested Route 3A corridor.

The board considering using $800,000 in roadway impact fees, anticipated to come from the large commercial development, to convince state department of transportation officials to move several reconstruction efforts for Route 3A up on their list of things to do.

“If we show a willingness to contribute, than they’ll show a lot more interest in doing this now,” said Michael DiBitetto, interim town council representative to the planning board.

Roadway impact fees must, by law, be used within six years. And, according to town ordinances, they must be used for road projects within specific zones where the new developments occur – in this case, west of the river and the Route 3A corridor.

Wal-Mart and Lowe’s have teamed up to present neighboring retail stores off Route 3A, south of Interstate 93’s Exit 10. The companies’ plans include widening Route 3A and adding turning lanes at the entrance to their site.

But between Exit 10 and the proposed site, said Town Planner Charles Watson, would be an “hourglass” formation, where multiple lanes in each direction would funnel down to two total lanes.

The state envisions aligning Goonan Road and Central Park Drive across Route 3A from one another, and perhaps lighting the intersection, Watson said.

He said the state Department of Transporation has determined that Wal-Mart and Lowe’s would be responsible for 23 percent, or $276,000, of that project.

If Wal-Mart and Lowe’s gain approval from the planning board, that money would go into an account until the construction project, currently slated for 2013, got underway, said Watson.

The planning board hopes to induce the state to move that project, and others intended to widen Route 3A from Hackett Hill Road to Exit 10, up in its schedule by chipping in the $800,000 in roadway impact fees, said planning board Chairman Richard Marshall.

“The planning board is saying, ‘We’d rather have that work done now than have than money sitting in an account somewhere,’” Watson said.

Said Marshall, “This is a discussion the board wants to keep having so we don’t want to lose sight of all the improvements that need to happen on 3A.”

Marshall said, ideally, all the work on Route 3A from Hackett Hill to Exit 10 could be completed before, or in conjunction with, the opening of the two stores.

Wal-Mart is proposing its largest “superstore” in the state, and its would-be neighbor, Lowe’s, is planning a large home improvement store with an outdoor garden center.

Watson said plenty of negotiations with parties, not the least of which is the state, are needed to make the project come together.

For example, he said, realigning Goonan Road and Central Park Drive would require the purchase of two private parcels of land.

The planning board’s next scheduled meeting with Wal- Mart and Lowe’s representatives is Monday, Nov. 27.
