The form of the land or topography largely determines the layout of your landscape. The steepness or flatness of your property determines the drainage pattern of the sit~. It also influences the design pattern of your Rain Garden. Use a line level, string line or your eyes to approximate the grade change of your site. Note the high and low points of your property and locate any slopes or depressions. Two-foot contour maps can be requested by calling the South Zumbro Watershed Partnership at 285-8982. Understanding the natural water system of a site is of major factor~n creating a functioning Rain Garden. During a rainfall, plot the areas of runoff concentration and follow the water to where it leaves your property. Note the location of the downspouts, puddles, and lines that divide areas of separate runoff direction. After the rainfall, identify the areas that are poorly drained. This includes all areas of standing water on your lawn: Measure the area and direction of runoff flow from your downspouts. OlC-- --\O;~----I 'lo "'" 06 _. _ ,"- 1 -~----:"-_.w# ,.,. .
