A. Overall:
1. Pursuant to 15A NCAC 02T .0606(a), the Applicant shall maintain for drip irrigation sites: (1) a
minimum 50 foot setback to each property line and (2) a minimum 100 foot setback to each
habitable residence under separate ownership. Pursuant to 15A NCAC 02T .0606(b), the Applicant
shall maintain for treatment and storage units: (1) a minimum 50 foot setback to each property line
and (2) a minimum 100 foot setback to each habitable residence under separate ownership.
Currently, Pea Ridge Developers, LLC, owns the parent Parcel No. 0018070 that Chatham County
will subdivide for Firefly Overlook. Based on the Chatham County GIS and the submitted
application package, Lot 6 SFR (Future Parcel No. 0096743) will not meet the setback requirements
listed above for the adjacent Lot 5 (Future Parcel No. 0096742) and Lot 7 (Future Parcel No.
0096744) when the Applicant sells the properties to the future homeowners.
While setback waivers are not required at this time, the Division strongly recommends that the
Applicant obtain all setback waivers pursuant to 15A NCAC 02T .0606(c) in their name based on
the proposed subdivision layout to avoid inconvenience for future homeowners. Otherwise, the
Division will issue this permit for construction only until we receive all recorded setback waivers.

G. Soil Evaluation:
A 40.5% drainage coefficient is being proposed. Per the DWR Soil Scientist Evaluation Policy and
the EPA Process Design Manual: Land Treatment of Municipal Wastewater Effluent (EPA 625/R-
06/016), a DC of 4-10% is recommended. How has the recommended drainage coefficient been
determined? Additionally, there is a large variance in drainage coefficient between this site and
surrounding lots despite very close proximity and similar soil types. Please explain the reasoning
for this variance
