is there a slope that the house sits on that you can put a swale uphill of to move water around the foundation? are there planting restrictions that would prohibit using thirsty perennials to draw water away? (n.b. you want something NOT with aggressive roots fi ther'es already a foundation issue)
how far out is this place? i may be conned into goign up for a workday to look at some options with you, and move some stuff about in useful fashions.
The cabin sits in the flattest portion of the property. Unfortunately this is also a depression in the slope. The north side of the cabin has a swampy mosquito factory 10' away from the front entry. There is a swale uphill and gutters so basic management was done.
From what I can determine the problem has lees to do with runoff and more to do with bottom up seepage. Basically the crawlspace is finding the natural water table level. The slow level of accumulation in the sump is mostly to do with the clay soil (once wet moisture percolates through it slowly.
It is a designated wilderness lake which means there are some restrictions.
The cabin is about 20 min south of Hibbing. I am planning a trip up sometime in the near future on my own. They have a recovered Oak floor which I plan on installing. He acquired it probaly 30 years ago and has been getting iin the way ever since. That may be the best time to perhaps have a larger more general work and hangout day or weekend.
