Problem Drainage Technique Identification
Now that you have identified the general drainage characteristics of your property, it is important to get an idea of whether you should consider your drainage observations as problematic to slope stability and erosion control. If you note any changes in your slope geometry or surface characteristics during wet weather, it is very likely that drainage is driving the failure.
Consequently, it is important to know the initial condition of your property in order to assess any changes. Should you have concerns, get some technical assistance. Once you've identified problem areas, appropriate drainage techniques in the table below can be reviewed which may address your drainage problem. One or more of these techniques can be chosen to make up your drainage system. Also refer to the section on drainage systems for more details.
