Turn the earth, plant and hoe. Water! Sunshine! Watch things grow.With a vision of intellectually disabled people learning to tend a garden and share in the everyday miracle of growing food, the selectmen approved a license agreement allowing Cornerstone Home & Gardens Inc. to teach gardening on a small patch of town land at the former McKeon Farm on Old Stagecoach Road.\u201cWe\u2019re going to set up an educational gardening experience for individuals with disabilities,\u201d Cece Berger of Cornerstone told the selectmen. \u201cIt could be adults who live in town, or students.\u201dThe printed agreement reviewed by the selectmen said the gardening program would serve \u201cindividuals on the autism spectrum\u201d but Berger told the selectmen she\u2019d like to change that to the \u201cindividuals with intellectual disabilities\u201d \u2014 a broader, more inclusive wording.The $1-a-year agreement gives Cornerstone 5,000 square feet \u2014 about an eighth of an acre \u2014 at the town\u2019s 42-acre McKeon Farm tract between Ridgebury and Old Stagecoach roads. It began Friday, Feb. 1, and runs through the end of 2019.Under the agreement Cornerstone is allowed to teach \u201cfive to ten\u201d disabled individuals and is required to \u201cprovide constant supervision\u201d while they\u2019re on the site.Cornerstone is allowed one bus trip to and one bus trip from the site each day.At the selectmen\u2019s meeting a Ridgebury neighbor in the audience, John Katz, asked about parking accommodations for the adults who\u2019ll be on the site, working with the disabled gardeners.There would be five or six cars on the site, at most, he was told, and no need for a formal parking area.Under the agreement no pesticides or herbicides may be use on the town\u2019s property.Cornerstone is also required to \u201cmaintain the site in a clean and orderly fashion\u201d and provide monthly reports to the Conservation Commission, the town agency which manages McKeon Farm along with other open space areas.The Conservation Commission also has the right \u201cto inspect the site from time to time at its sole discretion.\u201dThe agreement was approved unanimously at the Board of Selectmen\u2019s Jan. 23 meeting.\u201cIt\u2019s a great thing you\u2019re doing,\u201d Selectwoman Barbara Manners said.
