This proiect is a home addition. A small bathroom and a bedroom are planned. The existing home is already built in buffer
zones for an intermittent stream and the proposed additions will also overlap these buffer zones. The planned additions will
expand space for a growing family and provide an alternative outdoor exit on the bedroom side of the home. The owners
propose to install a cistern with a passive drawdown and a rain garden to treat stormwater and provide diffuse flow.

D. Stormwater
1. Provide a description of how diffuse flow will be maintained through the protected riparian buffers (e.g., re -planting vegetation
or enhancement of existing vegetation, gutter splash pads, level spreader to control of runoff from impervious surfaces, etc.).
The total increase.in impervious surface in the, buffer for this project will be 583sf, However, the size of the proposed
additions are 813sf. Stormwater detention and treatment devices are proposed to capture the linch storm volume from this
larger surface area. A 500 gallon cistern with a small rain garden in series will accommodate this volume. Stormwater will be
routed through gutters to the cistern and rain garden system. The stormwater plan for this site has been oversized to provide
increased capture and treatment while also providing water storage for gardening use.
la. Show the location of diffuse flow measure(s) on your site plan. Shown on Sheet 2
1b. Attach a completed Level Spreader Supplement Form or BMP Supplement Form with all required items for each proposed
measure.
1c. Attach an Operation and Maintenance (O&M) Form for each proposed level spreader or BMP. O&M included.
2. For Major, Catawba, and Goose Creek variance requests, provide a description of all bestmanagement practices (BMPs) that
will be used to minimize disturbance and control the discharge of nutrients and sediments from stormwater.
2a. Show the location of BMPs on your site ,plan.
2b. Attach a Supplement Form for each structural BMP proposed.
2c. Attach an Operation and Maintenance (O&M) Form for each structural BMP proposed.
E. Demonstration of Need for a. Variance
The variance provision of the riparian buffer rules allows the Division or the Environmental Management Commission to grant a
variance when there are practical difficulties or unnecessary hardships that prevent compliance with the strict letter of riparian
buffer protection.
1. Explain how complying with the provisions of the applicable rule would prevent you from securing a reasonable return from or
make reasonable use of your property. Merely proving that the variance would permit a greater profit from the property shall
notvbe considered adequate Justification fora variance..Th�p Division will consider whether the variance &the minimum possible
deviation from the terms of the applicable Buffer Rule that shall make reasonable use of -the property _possible.
Applicant cannot construct an addition on the east side of the house without impacting the buffer. Locating the addition on
the west side at the part of the house in zone 2 is impractical due to construction constraints and building code. Placing the
addition on the east side allows for secondM egress at the bedroom wing of the house.
FORM: VAR 10-2013 Page 5 of 6

2. Explain how the hardship resuits.from application of .the. Buffer Rule to the property rather from other -factors such as deed
restrictions or other hardships (e.g. zoning setbacks, floodplains, etc).
The existing home was built prior to buffer rules and any additions on that side require construction in the buffer.
3. Explain how the hardship results from physical nature of the property, such as its size, shape, or topography, which is different
from that of neighboring property.
The size and shape of the property, including the original home design and a stream that was moved onto the property
boundary created the necessity of impacting the buffer for the proposed addition.
4. Explain whether the hardship was caused by the applicant knowingly or unknowingly violating the applicable Buffer Rule.
The applicant did not knowingly cause the hardship by violating the rule.
5. For Neuse, Tar -Pamlico, Jordan Lake and Goose Creek only: Did the applicant purchase the property after the effective date of
the applicable Buffer Rule and then request a variance?
yes
6. Explain how the hardship is rare or unique to the applicant's property, rather than the result of conditions that are widespread.
The placement of the house is such that any additions on the east side of the house require buffer authorization.
F. Deed Restrictions
By your signature in Section G of this application, you certify that all structural stormwater BMPs required by this variance shall
be located in recorded drainage easements, that the easements will run with the land, that the easements cannot be changed
or deleted without concurrence from the State, and that the easements will be recorded prior to the sale of any lot.
G. Applicant's Certification
I, ��` �'� fdL(� (print or type name of person listed in Section A, Item 2), certify that
the informati n included on As permit application form is correct, that the project will be constructed in conformance with the
approved plans and that d restrictions in accordance -with Section F of this form will -be recorded with ail required permit
conditions. /

PASSIVE DRAWDOWN DEVICE DETAIL:
CONSTRUCTION, INSTALLATION, AND MAINTENANCE OF THE PASSIVE DRAWDOWN IS SUGGESTED TO BE CONDUCTED IN ACCORDANCE WITH PASSIVE
DRAWDOWN DEVICE_ (PDD) UNIT FOR RAIN WATER HARVESTING: PARTS, ASSEMBLY, INSTALLATION, AND MAINTENANCE BY MITCH WOODWARD, KATHY DEBUSK,
AND DR. BILL HUNT:
THE PASSIVE DRAWDOWN DEVICE (PDD) CAN BE INSTALLED IN A PRE-EXISTING ORIFICE OR A CREATED ORIFICE IN THE CISTERN. THE PDD CONSISTS OF A BALL VALVE
THAT CAN BE OPENED AND CLOSED TO FACILITATE THE PASSIVE DRAWDOWN OF THE DETENTION VOLUME WITHIN THE CISTERN.
RECOMMENDED COMPONENTS FOR THE PDD ARE LISTED BELOW, AND CORRESPOND TO THE ABOVE PARTS DIAGRAM FROM LEFT TO RIGHT:

THESE PARTS ARE NEEDED TO STEP DOWN THE DIAMETER OF THE ORIFICE TO THE BALL VALVE AND END CAP, WHERE THE DIAMETER OF THE PDD REQUIRED CAN BE
DRILLED INTO THE UNDERSIDE OF THE END CAP.
THE STAINLESS STEEL WASHING MACHINE CONNECTOR HOSE CAN BE ATTACHED TO THE CPVC PIPE AND USED AS A SECONDARY FILTER TO DECREASE THE
LIKELIHOOD OF THE PDD CLOGGING.
FOR THE PROPOSED 500 GALLON, 48''X71" CYLINDRICAL CISTERN FROM POLY -MART (SHOWN IN "CISTERN DETAIL"), THE DRAWDOWN SHALL BE PLACED 4.5" ABOVE
THE BOTTOM OF THE CISTERN BASE IN ORDER TO SET A DETENTION VOLUME OF 470 GALLONS. THE CISTERN COMES WITH A 12' BULKHEAD OUTLET FITTING NEAR THE
BOTTOM OF THE CISTERN AT THIS LOCATION. A SEPARATE HOSE BIB CAN ADDITIONALLY BE INSTALLED ON THE CISTERN IF DESIRED AS AN OPTIONAL OUTLET TO
QUICKLY RELEASE THE DETENTION VOLUME IF NEEDED FOR EMERGENCY OR FOR USE BY THE OWNER.
FOR THE PROPOSED CISTERN, A -,J" DRAWDOWN ORIFICE_ PROVIDES A DRAWDOWN TIME OF APPROXIMATELY 2.47 DAYS FOR THE FULL DETENTION VOLUME OF 470
GALLONS.
