SITE PLAN
GRADING AND DRAINAGE PLAN
1. Storm water from infiltration pond should be directed to the ditch to the south through a
swale rather than overland
2. Fire lane is adequate in width and strength. Communications with ERFD should occur
regarding if trucks turn radius are met with curves provided around building
UTILITY PLAN
3. Hydrant coverage is now sufficient.
4. Maintain lift station operation during upgrade procedure. Flow of sewage could be
collected in upstream structures via honey wagon (for low demand lines), or temporary
pumps placed in an upstream structure and connected to the existing 3” FM at some point
downstream of the wet well. Contractor will need to provide method and means for the
upgrade process that will be acceptable to the City. – Developer has responded this will
occur.

5. Recommend the new 4-inch forcemain to be installed via directional boring from the wet
well to the existing sanitary manhole, which will require core drill and boot seal. Ex. San
MH lies close to Mn/DOT ROW, permit may be required. – Developer has responded
this will occur.
6. Recommend a Variable Frequency Drive pump to mitigate flow surge. Will be
determined during final plat and final design.
7. Are the power source and control panel sufficient with the upgraded pumps? Will be
determined during final plat and final design.
8. Full plan set of the lift station including mechanical and electrical is required. Developer
has responded this will occur during final plan and final plat design
9. Pumps and appurtenances will require final approval of the City Utility Manager.

verify infiltration is met
