Part 2: Proposed Activity
(Please include attachments if the room provided is insufficient.)
1. Description of proposed activity [Also, please attach a map of sufficient detail (such as a plat map
or site plan in Adobe (pdf) format) to accurately delineate the boundaries of the land to be utilized
in carrying out the activity, the location and dimension of any disturbance in the riparian buffers
associated with the activity, and the extent of riparian buffers on the land. Include the area of
buffer impact in W.:
A 27'x24' addition will be added to the rear of the house located at 105 Breckenwood Dr.
in Cary, NC. One Sugar Maple Tree will be planted in the front yard and one leyland
_cypress tree will be planted in the back yard. -

Version 6 July 2009
2. Fill in the table below to identify the square footage of impact to Zones 1 & 2 in the protected
riparian buffers and the required mitigation (Fill in the impacts portion of the table, even if
mitigation is not required):
Buffer Impact
Zone of Impact in Number Purpose for Multiplier Required
Impact Square Feet (Indicate on the Impact Mitigation
Plan Sheet)
Zone 1 0 3
Zone 2 169 Home Addition 1.5
Total 169
*Zone 1 extends out 30 feet perpendicular from the most landward limit of the top of bank or the rooted herbaceous
vegetation; Zone 2 extends an additional 20 feet from the edge of Zone 1.
3. State reasons why this plan for the proposed activity cannot be practically accomplished, reduced
or reconfigured to better minimize or eliminate disturbance to the riparian buffers:
Impractical to move existing house which dictates placement of addition..-.-.
4. Description of any best management practices to be used to control impacts associated with the
proposed activity (i.e., control of runoff from impervious surfaces to provide diffuse flow, re-
planting vegetation or enhancement of existing vegetation, etc.):
-- ---- -- ----
The zone between the impervious structure and the stream is planted with grass and a row
of trees.
5. Please provide an explanation of the following:
(1) The practical difficulties or hardships that would result from the strict application of this Rule.
A useful addition would not fit while maintaining a 50 foot buffer. This rule was not in
-place when the land was purchased and it was selected for it's size to allow for future
-expansion. _ __
(2) How these difficulties or hardships result from conditions that are unique to the property
involved.
The house is where it is, the stream is where it is, and there isn't much more to it._______
(3) If economic hardship is the major consideration, then include a specific explanation of the
economic hardships and the proportion of the hardship to the entire value of the project.

Part 3: Stormwater
1. Provide a description of all best management practices (BMPs) that will be used to control
nutrients and sedimentation impacts associated with the proposed activity. Please ensure to
include all applicable operation & maintenance agreements and worksheets for the proposed
BMPs. Also, include the BMPs on your plan sheets.
Nutrient and sedimentation should be reduced due to reduced lawn area. Stormwater
_runoff will be reduced by locating the gutters on the new addition toward the center
of the north and south walls with flow directed north and south.
2. Attach a description of how diffuse flow will be maintained through the protected riparian
buffers. Please ensure to include all applicable operation & maintenance agreements and
worksheets for the proposed diffuse flow measure(s). Also, include the diffuse flow
measure(s) on your plan sheets.
3. What will be the annual nitrogen load contributed by this site after development in pounds per
acre per year without structural BMPs (stormwater pond, wetland, infiltration basin, etc)?
Attach a detailed plan for all proposed structural stormwater BMPs.

Version 6 July 2009
Part 4: Proposed Impacts and Mitigation
Provide a description of how mitigation will be achieved at your site pursuant to 15A NCAC 2B.0242
for the Neuse Basin and 15A NCAC 213.060 for the Tar-Pamlico Basin.
Mitigation will be in the form of two tree plantings shown on the plan following the request form.
One additional leyland cypress tree in the zone 1 buffer and one sugar maple tree in the front yard.
If buffer restoration is the method you are requesting, be sure to include a detailed planting plan to
include plant type, date of plantings, the date of the one-time fertilization in the protected
riparian buffers and a plan sheet showing the proposed location of the plantings. A guide to
buffer restoration can be downloaded at the following website:
http://www.neeep.net/news/reports/buffers.pdf
If payment into a buffer restoration fund is how you plan to achieve your mitigation requirement, then
include an acceptance letter from the mitigation bank you propose to use stating they have the
mitigation credits available for the mitigation requested.
Part 5: Deed Restrictions
