ALLISON TREE CARE, INC. <br /> 1312 CULMEN STREET <br /> MADISON, WI 53713 <br /> 608 257-4126 <br /> December 20, 2001 <br /> William Gilbert <br /> 1750 Beach Road <br /> Verona, WI 53593 <br /> Re:Tree Inspection and Protection Plan Town of Westport Development <br /> Dear Mr. Gilbert: <br /> At your request I have visited your development site in the Town of Westport to inspect <br /> and describe the tree cover and provide a tree protection plan to protect two oaks during <br /> development. Attachments to this report include two aerial photographs locating the <br /> property, a site grading plan by TDI Associates and four photographs taken by me on <br /> December 19. <br /> The site is a wet, disturbed, non-native woods consisting primarily of smaller stem <br /> cottonwood, boxelder,willow, black locust, dogwood and honeysuckle. Near the road <br /> are two red oaks, a single trunk ( 28.5 inches in diameter) approximately 14 feet from the <br /> asphalt road and a double stem(15 inches and 14 inches in diameter) approximately 30 <br /> feet from the road. Both trees appear in good condition with no significant trunk decay <br /> and normal bud development and distribution. <br /> I recommend the following for a tree protection plan to avoid damage to the oaks during <br /> • construction: <br /> 1 1. Use a chain link fence or a snow fence with a 2x4 wood top rail to enclose the <br /> oaks with a minimum distance of 20 feet from the trunks. The fence should be <br /> installed and completely enclose the trees prior to any construction work and <br /> remain in place until all danger of root damage has passed. <br /> 2. Avoid any soil compaction or grading within the protected area. <br /> 3. Route all utilities outside of the protected zone. If it is absolutely necessary to <br /> pass through the zone then tunnel rather than trench in the root zone. <br /> 4. Communicate to all construction workers and subcontractors the importance of <br /> tree protection, place signs on the fence designating the area as a tree protection <br /> zone, and assign responsibility to enforce the tree protection plan to someone with <br /> authority on the general contractor's staff. <br /> 5. To avoid the introduction of oak wilt, be sure no pruning is conducted from April <br /> 15 through October 1. If a wound is made during that time be prepared to <br />
