Ms. Katie Larsen <br />08/06/2025 <br />Page 8 <br />Nature Refuge North Addition Engineering Review <br />lift station. Future maintenance should be covered. Sheet piling or <br />trench box should cover any embankment issues along the street <br />side if for some reason the lift station needed to be repaired. <br />WSB (5/23/2025) Complete <br /> <br />d. Can the 12’ build at the northwest corner serve the street extending north <br />outside the service area if desired? <br />Carlson (4/25/2025) No. Currently it does not. Please advise if this sanitary <br />line needs to service the area to the north. <br />WSB (5/23/2025) Engineering to verify with final plat <br /> <br />3. Insulate all sewer with less than 7' cover <br />a. Consider lowering the watermain to limit conflicts between services and <br />mains <br />Carlson (4/25/2025) Watermain will be lowered as-needed for service <br />conflicts – this will be shown with final plans. <br />WSB (5/23/2025) To be completed with final plans <br /> <br />4. WSB (8/6/2025) Lift station pumps shall be 5 HP for ultimate build (~200 gpm at ~55’ <br />TDH). <br /> <br />5. WSB (8/6/2025) The permanent standby natural gas generator does not need to be <br />installed at this time. Instead, a receptacle for the City’s portable generator and a <br />manual transfer switch shall be installed now. The concrete slab and conduit for the <br />future generator shall still be installed now. <br /> <br />6. WSB (8/6/2025) Lift Station Plan <br />a. Change valve vault access and bypass castings to a single 30”x30” hatch. <br />b. Extend concrete slab 3’ past valve vault. <br />c. Shift wet well vent pipe to west side of hatch so as not to obstruct access <br />from driveway (still behind hatch when open). <br /> <br />7. WSB (8/6/2025) Electrical Plan <br />a. Confirm that 240V, 3-phase power is available. <br />b. Remove VFDs. <br />c. Update pump and mixer horsepowers. <br />d. Shift light pole southeast so it’s not between wet well and valve vault. <br /> <br /> <br />• Transportation <br /> <br />The proposed development will have a primary access from Haywood and Glenwood <br />Drives. Which is the shortest route out the proposed neighborhood. The City also <br />requires a connection to Andall St. to the existing Arena Acers Development. The City has <br />an existing right of way to provide access to the easterly property. <br />Per the traffic study the connection to Andall St will receive minimal traffic, however it will <br />provide connectivity for public safety and the neighborhoods it serves. This connection is <br />in conformance with the City’s Ordinances for adjoining adjacent subdivision for <br />reasonable circulation of traffic. The City of Lino Lakes’ Comprehensive Plan requires <br />neighborhood street connections for reduced travel times and linking neighborhoods <br />together. <br /> <br />Page 114 of 168
