Day 11 Dig one cubic foot hole (12rdquox12rdquox12rdquo)2 Fill the hole with water to saturate the soil 3 Let drain overnight

Day 21 Lay a stick over the hole2 Refill the hole with water to the

Step 2Create a Basic Plot Plan

Measure your propertybull Start with one dominant point to measure from (ie a wall corner)bull Locate features that stay (walls hardscape trees fences etc) bull Alternate use outside source (Property Description Google Earth)

Evaluate your mini-watershed

bull Slopes amp Hillsidesbull How steep is your slopebull Run = Horizontal distance

bull Rise = Vertical distance

bull Slope = (Rise Run) 100

Evaluate your mini-watershed

Estimating Slopes amp Hillsides

bull Estimate your slope on your L-2 plan for your site evaluationbull Use Soil Building Mulch type (Brush Mulch Chipped Mulch with specified texture) on all

slopesbull Decomposed Granite (DG) used only on slopes less than 5
