Ms. Katie Larsen 09/04/2025 Page 11 Wetland buffers meeting minimum and average requirements will be required around all wetland areas following construction. •Landscaping A Landscape Plan for Wilkin son Waters Addition has been submitted and will be reviewed by staff and the City’s Environmental Coordinator. The Environmental Coordinator will provide separate comments. •Floodplain The proposed pond berm and trail grading appears to result in floodplain fill. Calculation of compensatory cut must be provided to ensure there is no net fill in the floodplain. This remains an open comment. A one-time deposition of 100 cubic yards of floodplain fill is allowable, fill in excess of this volume requires compensatory cut within the floodplain. •Drainage and Utility Easements Roadways are proposed within right-of-way and lots include standard drainage and utility easements. Larger drainage and utility easements will be required to be provided over any utilities outside the right of way and any surface water management features The plan shows White Bear Lake Township easements (30’ and 50’) with the existing sanitary sewer and watermain crossing the site. White Bear Lake Township has commented that the Township has no easement and that the lines were installed and owned by the North Oaks Company. Please update the linework or provide a record showing the easements. Comments: 1.For pipe within drainage and utility easements that is greater than 10’ deep, easements must be set with a width equal to the pipe depth. For example, a 20’ deep pipe would require 20’ wide easements on either side of the alignment. a.This appears to be needed for P-101, P-102, P-111, P-110, and P-202. ISG Response (7/14/2025) – Easement lines have been updated to provide 20’ minimum or 1:1 easement for storm sewer outside of the ROW. WSB Response (8/6/2025) – D&U must be expanded between L4 B1 and L5 B1 to accommodate the >10’ pipe depth between ST-110 and ST-109. D&U must be expanded between L1 B1 and L2 B1 to accommodate the >10’ pipe depth between ST-202 and ST-201. WSB Response (9/4/2025) – Remains an open comment. 2.Drainage and utility easements are needed for all proposed rain gardens up to the extents of the 100-year HWL. ISG Response (7/14/2025) – D&U easements have been added around proposed raingardens. WSB Response (8/6/2025) – Please specify document showing these easements, none are evident on sheet A0-16 of the Preliminary Plat Plan Set.
