In the formula, "I" =Volume rate of wastewater entering the soil averaged <br /> over the gross developed area in inches per year." The gross developed area is taken to mean <br /> an entire subject parcel - and consequently the entire project area, and not just an effluent <br /> disposal area, or the exclusion of a remaining or unused area of a parcel, for example. Therefore, <br /> the entire subject property acreage of 444 acres must be accounted for in the Hantzche- <br /> Finnemore Equation since this is the gross acreage of all the lots that may be developed. <br /> Respectfully submitted, <br /> CHESNEY CONSULTING ` p <br /> No. 04675 e <br /> � <br /> Expires: 6.3yo� <br /> Cn <br /> Don Chesney, R.E.A. -1x'44 <br />' �a:^�7EW•'v <br /> I <br /> Page 2 of 2 j <br /> i <br /> Chesney Consulting <br />
