RE: Kinnakeet Shores Wastewater Disposal System Renewal
To whom it may concern:
The purpose of this letter is to summarize the existing and proposed development regarding the
Kinnakeet Shores wastewater collection, treatment and disposal system at Avon, N.C., and to
provide updated data for the renewal of existing permit no. WQ0002284. The facility had an
original permitted capacity of 220,000 gallons per day with a high rate rotary distributor type
disposal system, of which 50,000 gallons per day of capacity has been constructed. From a review
of the treatment plant operator's records, the facility is currently operating at a peak month rate of
15,000 gallons per day. The new permit requires a new hydrogeological study prior to exceeding
50,000 gallons per day of treatment capacity.
Since lots have been platted which, if all developed, would result in wastewater flows in excess of
50,000 gallons per day, we discussed the need for ongoing communication between the Dare County
building inspection department and the Division of Water Quality as additional building permits
are issued and certificates of occupancy granted, to assure that appropriate measures are initiated
to expand the treatment facilities in advance of reaching the 50,000 gallon capacity.
The long-term plan for Kinnakeet Shores is to convert the treatment and disposal facility to a re-
use system prior to reaching the 50,000 gpd capacity of the existing plant. Preliminary engineering
for this conversion is in process.
The following is the information we have tabulated information on the number of lots, status of
development, and sewer allocations. We have also researched the current status of permits and
ownership. This information follows:
1. There are currently 154 platted lots which have existing sewer lines available. The number
of lots by phase and sewer allocations are tabulated on the following page, along with
allocations made for commercial connections. The current status of development is also
indicated.
Based on this tabulation, the amount of 95,000 gallons per day could potentially be needed to
serve all current platted lots and commercial development, based on DWQ standard flow
criteria, at complete build -out.

252-261-3266 ■ Fax: [phone] E-mail: [e-mail]

2. The allocation to actual developed lots and completed commercial areas is approximately
46,000 gallons per day. However, the actual flow experienced in the peak month this past
summer was approximately 15,000 gallons per day, only one-third of the allocation.
3. It appears, based on the historical data, that approximately 78 additional homes can be
accommodated by the existing treatment facility, based on an allocation of 450 gpd/house, to
bring the facility to its current capacity of 50,000 gpd, at which time the reuse system will
need to be operational.
4. The rate of residential development has averaged approximately 15 houses per year over the
last 10 years; at that rate we do not anticipate reaching the 50,000 gallon per day level for
approximately 5 years. If the new developer is successful in his marketing effort, then the
time frame could be shortened. From a conversation with the developer's representatives,
there are currently two outstanding building permits for which CO's have not been issued.
These are included as developed lots on the Attachment.
5. The land available for future development has been transferred to Outer Banks/Kinnakeet
Associates, LLC, Ray Hollowell, Manager. The wastewater treatment facility and disposal
site are also in the name of Outer Banks/Kinnakeet Associates, L.L.C.
Enclosed is the completed renewal application along with copies provided in triplicate. Also
included are (5) copies of the original approved permit, WQ0002284, in association with each
subsequent renewal application approval.
If you require additional information or if we may be of assistance and any way please do not
hesitate to contact our office. We thank you for your time and consideration of this matter.
