What should be shown on the plot plan?
If the site is a large acreage, focus on the area (to be) developed. See the example, on our website noted above. Setbacks by septic components to geographic features or development required by code are shown on this example, and must be taken into consideration when you are deciding where to put the replacement septic components. Show the following: all wells within 200 ft of the property, – a north arrow, the scale (the preferred scale is approximately 1 inch equals 30 ft), – the location from two perpendicular lot lines of a minimum of two test holes(only one test hole is required for a repair evaluation) Note: the test holes must be in the area you propose to build a (replacement) drainfield, – the location of the existing drainfield failure, if it is for a repair evaluation, – all development, if there is any, – any geographic feature that requires setback, – a path flagged to the test holes, if they are in a dense vegetation area.
