Area 1 (Barrett Farm Unit) includes erosion control over 500 linear feet, removal of 45 vegetation items in the rear yard, root grinding, tree removal with vine clearing in the barn foundation area, treatment of invasive vines, and an optional pool removal and grading task. Area 2 (North Bridge Unit) requires tree removal of 18 trees near Monument Street Parking Lot and 9 trees near Sargent Field, all flush-cut at base without stump grinding, plus invasive vegetation treatment and pasture mowing. Area 3 (Meriam's Corner) involves mowing a 2.0-acre field, cutting vines and removing collapsed trees, felling 20 dead ash trees in a wooded area, and clearing vegetation along 1,200 linear feet of stone walls. Area 4 (Jones-Stow Farm) requires removal of 850 linear feet of livestock fence, clearing of two 2-acre areas with stump grinding, and erosion control installation with seeding. Area 5 (Brooks Village) includes erosion control over 400 linear feet, removal of hazardous trees, clearing and seeding of up to 3.0 acres across multiple parcels.
