DOVER — A large sports complex could be coming to the area between Littleworth and Tolend roads in Dover. The project would involve moving the Seacoast Mavericks baseball team to the new facility.

The Planning Board Tuesday will review a proposal from USA Training Centers out of Newington to rezone 106.45 acres of land on Littleworth Road, Tolend Road and Columbus Ave. to commercial use.

The development would include a 2,000 seat baseball stadium, five full-size baseball fields, a three-floor observation building, a 90,000 square-foot training field with a seasonal dome, a 15,000 square-foot indoor baseball training facility and walking paths and park features. Additionally, the site could accommodate restaurants, hotels, convenience stores and additional parking.

“The project mission is to create a Sports Complex set in a park like atmosphere that specializes in Baseball & Softball Training that will afford the New Hampshire Seacoast area athletes a top flight facility to both train and showcase their abilities to College and Professional Scouts,” according to the project narrative provided by USA Training Centers to the Planning Board.

The “anchor” of the project would be the Mavericks Stadium, according to the narrative, which would be home to the Seacoast Mavericks, charter member of the Futures Collegiate Baseball League, which plays 26 home games each summer.

The Mavericks currently play their home games at Leary Field in Portsmouth.

City Councilor Dennis Shanahan said he had received concerns from several residents in the neighborhood of the proposed development. He said the project is in a very early stage, and that several reviews would take place before the project became final.

“I am committed to ensure that all steps in this process are open and transparent,” Shanahan said in an email Monday afternoon.

On Tuesday, the Planning Board will discuss the proposal and possibly post the zoning amendments. If posted, a public hearing would be held on Jan. 24 with abutter notices mailed out. A second public hearing may be scheduled before the Planning Board voted on the project.

The proposal would then move to the City Council, where further discussion and public hearings would be conducted before a final vote was taken.

Shanahan encouraged residents to attend these meetings and be a part of the process.

USA Training Centers trains baseball and softball players in the Seacoast area. It currently operates a facility in Newington.
