r Zoning File #2338 February 12, 1998 Page 2 Fifth Tee Improvements Please review Exhibit E-1. Applicant proposes doubling the area of the existing 5th tee and creating a pond to the south side of it in an area that is low but not an Orono designated wetland and not appearing on the National Wetland Inventory. Applicant proposes a pond approximately 6' deep at the center, and somewhat triangular in shape, being approximately 100' in diameter and approximately 6,000 s.f. or 0.15 acre in area. This project involves the movement of approximately 1,000 cubic yards of material. Eighteenth Hole Improvements Please review Exhibit E-2. The 18th hole improvements are slightly more extensive, involve the excavation of a pond approximately 60' wide and 200' in length or 12,000 s.f. in area, expansion of the 18th hole tee boxes, and general filling in a low area near those tee boxes and adjacent to the 9 acre pond in the eas^ central portion of the course. The pond is listed in the City protected wetland inventory as a Type 5 wetland, and is primarily open water. While no filling of the pond is proposed, the proposed grading would appear to be within the 26' wetland setback, hence technically a variance is required. This portion of the course has been maintained in mowed grass, and the proposed filling will have no significant added impact on the quality or quantity of runoff to the pond. It appears that the proposed new 1/4 acre pond will overflow to the east, underneath North Arm and eventually to the wetland complex at the north end of North Arm Bay before reaching the lake. The existing 9 acre pond discharges generally to the south through a second wetland and under West Branch Road before reaching Forest Lake. General Comments Neither proposed pond excavation involves impacts to existing wetlands. The creation of ponds at these strategic locations on the course will potentially be of benefit to the watershed in general by creating more runoff storage, allowing sediments and nutrients to settle or assimilate prior to runoff discharging to downstream areas in the watershed. The expansion of tee boxes is a normal and necessary improvement for golf courses, and at the locations proposed in this request, has no significant impact on the watershed or neighboring properties.
