Soil prep and grading
Most valley lots are sand, cobble, or compacted construction fill, none of which holds moisture or nutrients. We strip debris, rip or till the top layer, and blend in compost and topsoil so roots have something to grow into instead of hitting hardpan two inches down.
Grading is set to drain away from the house and away from patios, with the finish elevation dropped so sod sits flush with walks and driveways rather than an inch proud of them.
