<br />Ms. Katie Larsen <br />3/4/2026 <br />Page 3 <br />7.Applicant to confirm the extent of runoff routed to Pond 2P in full buildout conditions <br />of Otter Crossing South. Any proposed future runoff must be included in the <br />stormwater calculations. <br />8.Pretreatment by way of sumped storm manhole or hydrodynamic separator at <br />structure STMH-10 must be provided for flows leaving the private site. <br />9.HydroCAD modeling must use dynamic storage-indication (Dyn-Stor-Ind) routing to <br />properly account for tailwater effects. <br />10.Existing pond maintenance and sediment removal to maintain original pond capacity <br />should be included in the project plans. Outlet structures and modifications to the <br />existing structures will need to meet current standards. <br />Water Supply <br />Water for the platted commercial lots is proposed to be served by connecting to the <br />th <br /> existing 8” water service stubs on the north side of 70 Street. Service for Lot 1 will <br />require extending across Lot 2. <br />Comments: <br />1.Easement will be required in favor of the Taco Bell site for utilities from the north side <br />th <br />of 70 Street <br />2.Hydrant coverage to be reviewed by City Fire Official <br />Sanitary Sewer <br />Sanitary sewer for the platted commercial lots is proposed to be served by connecting to <br />th <br /> the existing 6” sanitary sewer service stubs on the north side of 70 Street.

The anticipated <br />uses of the sites were accounted for in the traffic study and analysis conducted with the <br />original overall development. 70th St at Otter Lake Road will become a right in / out in the <br />future. <br />Comments: <br />1.Only one connection will be allowed to 70th Street on the north side and it will <br />ultimately need to line up to a similar single connection on the south side <br />2.Clarify the extents of what will be constructed as part of the 2nd Addition and what <br />will be constructed as part of the individual lot developments <br />3.Provide turning movements for emergency vehicles within the proposed sites <br />nd <br />Otter Lake South 2 – Engineering Review <br /> <br />
