Review File:Brookfield 8th Addition Preliminary Plat, Comprehensive Plan Amendment, Cul-de- sac Length Variance, Lot Depth variance and Front yard setback variance. September 30, 2016 Page 3 of 6 Lot • • 11 feet with a minimum widthof 1 RVIF Fmav%a• ® ® a ® • feet Wedand: *Note:Minimum Lot Width is measured at front yard setback line,property must abut built street. **Lot depth required is 100 feet for a width of 60 feet that is not encumbered by wetland,wetland setback area,floodway,or other unbuildable areas. Density. The R-1 Residential regulations for the MUSA area allows a net density of 3 units per acre(excluding wetlands and major road rights-of-way). The proposed density is 2.39 units per acre. Floodplains. There are floodplains within the boundaries of the project area, including both Floodway and Floodfringe. There shall be no fill placed within the Floodway. The Flood Insurance Study indicates that the flood elevation is 871.5 feet. The lowest floor of any proposed home will need to be at or above the Regulatory Flood Protection Elevation (RFPE), which is one (1) foot above above 871.5 feet. There is floodplain across portions of this site. According to the Flood Profile for Trott Brook,the Floodway elevation is approximately 871.5 feet. An Elevation Certificate will be required for Lots 1-5,Block 1 and Lots 7-12,Block 2,prior to the issuance of a Certificate of Occupancy,to ensure that the lowest floor elevation is at or above the Regulatory Flood Protection Elevation,which is the base flood elevation (871.5 ft) plus one foot of freeboard(State of Minnesota requirement). 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. There are significant wetlands on the property that will need to be delineated and encumbered with drainage and utility easements on the Preliminary and Final Plats. The project will be subject to review by the Lower Rum River Watershed Management Organization (LRRWMO) regarding both the wetland delineation as well as stormwater calculations. Note that City Code now requires a sixteen and a half foot (165) setback from a wetland edge and that the setback area be encumbered with drainage and utility easement. Ensure that all wetland setback atvas are entitrly within proposed drainage and utility easements. 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. 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. Per the Tree Inventory and Protection Plan,there are 7,726 inches of significant tree DBH on the property and there will be 3,544 inches of significant tree DBH remaining after grading, utilities, sidewalks and street are completed. This is the equivalent of forty-six percent (46%) of the significant tree DBH and meets the standards of the Tree Preservation Ordinance.
