The Housatonic Valley Association will hold its 26th annual auction Nov. 6 at 1 p.m. in Washington.

Festivities will take place at Washington Primary School at 11 School St.

Auctioneer Tim Luke, who has been featured on HGTV’s “Cash in the Attic,” will take center stage at 3 p.m.

He will be joined by co-auctioneer Greg Strahm.

Christine Baranski, HVA board member and costar of CBS’s “The Good Wife,” is co-chairwoman of the event along with Seth Meyers and Alexi Ashe, Sam and Lynn Waterston, Diane von Furstenberg, Linda Allard, Pam and Jack Baker, Robert Couturier, Diane Meier and Frank Delaney, Carolyn Klemm, Hamilton South, Anne Swift, Jon Favreau, Heather and Damian Woetzel and Judy Auchincloss.

Chris Zaima, of Washington, and Debby Bennett, of Kent Greenhouse and Gardens, will bring their expertise to the setting this year.

Music will be provided by Miles of Swing and the food will be catered by Executive Cuisine.

The auction will feature exotic vacations and weekend country getaways, theater and sporting event tickets, fine dining, home furnishings, antiques, artwork, outdoor gear and adventures and unique opportunities not available at any other event.

Honorary auction committee members at the diamond and platinum sponsorship level are invited to a special Bellini brunch reception hosted by Linda Allard and Baranski at Allard’s home from noon to 1 p.m. before the auction.

The auction has been a sold-out event for the past several years and raises over $150,000 annually for projects that protect land, rivers and local drinking water. Last year it grossed $250,000.

Proceeds from the event enable HVA to carry out its mission of conserving the natural character and environmental health within the communities of the Housatonic River watershed.
