The joint venture selected by the Department of Transportation to redevelop part of Stamford near the city’s train station gave $90,000 to the Connecticut Democratic Party’s federal account last year, including $32,500 in December.

DOT selected Stamford Manhattan Development Ventures in June to take charge of the $500 million project, including $35 million in state funding for parking garages.

Weeks after DOT told the joint venture it won, the family behind JHM Group, which belongs to the joint venture, gave $30,000 to the Democratic Party’s federal account.

Since the company is a prospective state contractor, its executives are prohibited from giving to the party’s state account, but are allowed to give to the federal account.

Executives from other joint-venture partners, including Ciminelli Development and AllPro Parking, gave another $27,500 in November.

In December, Paul Ciminelli and Dennis Penman, executives at Ciminelli Development, gave $2,500 and $10,000, respectively.

John and Raymond Gizzi, of ECCO III Enterprises, Inc., another joint-venture partner, gave $10,000 each last month, bringing the total to $90,000.
