LOCATIONS OF ALL COMPONENTS MAY BE VARIED AS NECESSARY AS LONG AS ALL MINIMUM DISTANCES AND SLOPES MEET THOSE REQUIRED. 8. PROVIDE POSITIVE DRAINAGE OF SURFACE WATER AWAY FROM ABSORPTION FIELD AREA USING DRAINAGE SWALES AS NECESSARY. 9. THIS SYSTEM IS BASED ON SOILS AND PERCOLATION INFORMATION PROVIDED BY HP GEOTECH. JOB NO. 108 543A, DATED OCTOBER 29, 2008. INDICATING AN AVERAGE PERCOLATION RATE OF 30 MIN/IN. (THE SOIL PROFILE CONSISTED OF APPROXIMATELY 1FT OF TOPSOIL OVERLAYING APPROXIMATELY 8 FT OF SILTSTONE/CLAYSTONE.) 10. THIS DRAWING DOES NOT CONSTITUTE AN ISDS PERMIT. PERMIT MUST BE OBTAINED FROM APPROPRIATE CITY OR COUNTY OFFICIALS. THE ENGINEER MUST OBSERVE CONSTRUCTED SYSTEM BEFORE BACKFILL AND PROVIDE REPORT TO COUNTY. 11.
