Based on my review of the information provided with the application and our visit to the site yesterday,I offer the following comments for your consideration: 1. Some of the proposed improvements are located within 5' of the property line including a boulder retaining wall and drain tile system. 2. One of the proposed trees is shown extending beyond the south property line. 3. The proposed retaining wall does not need to be designed by a Licensed Professional Engineer since it is less than 4' in height. 4. The proposed improvements are located within a drainage easement that has been granted to the neighboring property by the applicant. Approval of this application does not change the requirements of the agreement between the private property owners. 5. Grading improvements that have been approved on the neighboring property are intended to direct runoff around the corner of the lot where the improvements are proposed. 6. The proposed improvements will restrict drainage across the drainage easement; however, it does not appear that the improvements will have a negative effect on the neighboring property. 7. It is unclear how the proposed drain tile will be outlet but it is assumed that it will be outlet near the lake or connected to an existing drainage system located on the property. Please let me know if you have any questions or need additional information. Sincerely, BOLTON &MENK,INC. �� David P. Martini,P.E. Principal Engineer
