A new site evaluation ma~ be re, ired if the system is pro~sed for a different area on the pro~rty. SPECIAL CONDITIONS= The drainfielda cannot be constructed within the concave landform of the drainag~ swale. The lines must be install~t on straight slopes or convex surfaces and contoured ,to the natural landform. A pre-construction field a~akeout will be necessary to establish the locations and elevations cf the individual drainfield lines for beth systems. Refer to the enclosed stakeout procedure and the setback li~ for details to complete the stakeout.
