Please be advised that individual lot surveys will be required to include the following information above and beyond what is typically shown: Floodplain boundary (with note of no grading within floodway), wetland, and wetland setback. Wetlands. All wetlands and land within the (16.5) Sixteen and a half foot wetland setback must be encumbered within a drainage and utility easement. This area is shown within such an easement on the Final Plat sheet; however the Preliminary Plat Sheet refers to the Wetland Setback as a Wetland Buffer. Ensure that all wetland setbacks are identified as 'Wetland Setback" rather than 'Wetland Buffer". Trott Brook. A portion of the lots will back up to Trott Brook, which is a tributary of the Rum River. Thus, the project is subject to the Scenic River Overlay District, which includes a 100 foot setback from the OHW of Trott Brook and has controlled vegetative cutting standards as well. Additionally, lands within 300 feet of the OHW of Trott Brook are subject to Shoreland Management requirements. There is a Conservation and Trail Easement encumbering significant portions of the rear yards of Lots 1-12, Block 2 that will prevent any impervious surfaces or tree/vegetation removal in proximity to Trott Brook. Tree Preservation. A Tree Inventory and Preservation Plan was submitted and approved as part of the Preliminary Plat. Due to the presence of larger stands of oak trees, the Applicant has added a note regarding tree clearing activities shall occur prior to April 15 or after July 15 to minimize the potential introduction of Oak Wilt to the site on the Grading, Drainage, and Erosion Control Plan as well as the Tree Inventory and Protection Plan. Provide exhibits for Lots 4-8 & 16, Block 2 and Lot 1, Block 1 (in CAD format or equivalent, but send over as pdj) to illustrate what trees can be removed by a future homeowner. Landscaping. Each lot is required to have two (2) front yard trees installed. The plan currently shows the required two (2) front yard trees for each lot. The proposed trees are positioned in the boulevard area to serve as street trees (as spacing permits). Deciduous trees shall be at least one (1) inch in diameter and coniferous trees shall be at least five (5) feet in height. Each lot is subject to the City's topsoil requirement.
