Please be aware that the Applicant is responsible for meeting all requirements set forth in North
Carolina rules and regulations. The Applicant is also responsible for any oversights that occur during the
review of the subject application package. The Division may return the application as incomplete pursuant
to 15A NCAC 02T .0107(e)(2) if any omissions are made when responding to the outstanding items in

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 24 SFR (Future Parcel No. 0096761) will not meet the setback
requirements listed above for the adjacent Lot 23 (Future Parcel No. 0096760) 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.
