The following is in response to the November 3rd review letter. Preliminary Plat 1. The drainage and utility easement for the infiltration pond shall have a 10 -foot wide area around the top contour of the pond. This easement is for vehicle access to the pond for maintenance. • Ruds have revised the pond easement to cover 10' beyond the HWL of the pond and infiltration basin. Grading, Drainage, and Erosion Control Plan 1. The minimum pavement section required shall be the City of Little Canada's standard, which is 1.5- inches of wear course, 2- inches of base course, and 8- inches of class 5. • The pavement section detail has been updated to reflect the City of Little Canada's standards. 2. The two horizontal curves east of Labore Road are too short of radius curves. Both curve radii should be increased while still providing a minimum approach length of 40 -feet. The 40 -feet shall be measure from the center line of Labore Road. • Ruds have revised the road increasing the radii while maintaining the 40 -feet minimum approach. 3. The length of the proposed cul -de -sac is 516 -feet from the Labore Road right -of -way to the end of the cul -de -sac.
