How to Maintain and Care for Green Roofs

Solutions for Properties in Minnetonka You can always tell a Minnetonka yard that’s fighting its slope. Water doesn’t lie, it finds the weak spots every time. I’ve walked plenty of properties where a backyard starts beautiful in June, but by September, the patio is heaving, the grass near the pool looks like a marsh, and the homeowner is wondering how it got so bad so fast. The truth is, when you’re dealing with rolling terrain and heavy clay soils like we have around Minnetonka, you can’t just move dirt and hope gravity behaves. You need a plan that manages water from the surface all the way down through the subsoil. This is what I’ll walk you through here. You’ll see what actually causes drainage issues on sloped properties, how poor planning leads to cracked patios and shifting pool decks, and the smart drainage systems that can stop those problems for good. Whether you live near Lake Minnetonka or up in the higher ridges closer to Deephaven or Woodland, understanding how your yard sheds water is the difference between a property that lasts and one that’s constantly under repair. The Real Challenge of Sloped Minnetonka Yards Minnetonka is known for its hills, lakefront properties, and mature trees, but all that beauty comes with a set of challenges below the surface. Most of the soil here is dense clay. It holds water like a sponge and drains slowly, which means after every heavy rain, that water looks for a way downhill. If it doesn’t have a proper outlet, it ends up collecting right where you don’t want it, like along your patio, at the base of a retaining wall, or near your pool deck. I see this every season: homeowners trying to solve slope problems with a quick regrade, a layer of rock, or a simple surface drain. Those things might help for a while, but they don’t address what’s really happening underground. Clay soil doesn’t just get wet—it becomes saturated, expanding and contracting with every freeze-thaw cycle. When that happens under a patio or wall, it doesn’t matter how well-built the surface looks. The ground will move, and that movement cracks stone, shifts pavers, and slowly tears apart everything on top. The other challenge with sloped lots is how water interacts with gravity. It accelerates downhill, gaining momentum as it goes. When it hits a flat area like a patio, the water loses speed but not volume, pooling instead of flowing. That’s why I tell clients that “flat spots” on a sloped property are both an opportunity and a responsibility. They’re the best spaces to create usable outdoor areas, but they have to be engineered to handle water movement. I’ve worked on plenty of Minnetonka yards where the backyard has a beautiful view but terrible grading. You can have a perfect slope on paper, but if it directs water toward your house or creates a bowl effect between structures, you’ll end up with soggy soil and standing puddles that never dry. The goal is to move water off and away while keeping the surface level enough for comfort and usability. It’s a fine balance, but when it’s done right, it completely transforms how a property functions.
