Roseville Knowledge · Era-SpecificLake Owasso and Lake Josephine Lakefront Inspection Considerations
Lake Owasso and Lake Josephine homes in Roseville are gorgeous — and they sit on a seasonal water table that punishes original 1960s drain-tile, sump pump, and retaining-wall installations. Here's what we look for.
By Home Inspectors Roseville MN · Last reviewed May 2026
Drain tile — original clay vs. retrofitted
1960s clay tile silts over. We probe and run a hose test. See lakefront drain tile failure.
Sump pump — single, dual, or with battery backup?
On a lake lot, single-pump installations are not adequate.
Retaining walls — engineered or DIY?
Driveway-side retaining walls on sloped Owasso Hills lots are a frequent find.
Seasonal water staining
Spring snowmelt patterns tell us what summer hides.
Walkout grading
Negative grading at walkout doors floods finished space.
