In addition, an attempt was made to count the <br /> number of rural residences from a review of a 2008 air photo of the area. The <br /> assumption was made that one septic system is associated with each residence. <br /> F, Using this method, we concluded that at least 4 systems lie within the 1/-mile <br /> circle surrounding the site and at least 27 systems are within the 1-mile circle <br /> F, surrounding the Property (see topographic map in Appendix A). <br /> Permits pertaining to the septic systems in the immediate vicinity were <br /> reviewed at the EHD offices on August 24, 2009.
