Aaron,
Thank you for the additional information provided on June 16, 2016. Unfortunately, legal counsel for the
Environmental Management Commission (EMC) did not agree that major variance requests could be delegated
to Division staff without going through the rulemaking process. Therefore, your request has been placed on the
September meeting agenda of the Water Quality Committee of the EMC.
I reviewed the additional information that you provided and have the following items that need to be corrected.
1. The proposed rain garden is located in Zone 1 not Zone 2 as listed in the amended application. List the
impact for the rain garden in Zone 1 and total the impacts as shown on the attached markup of
application.
2. Mitigation is also required for the rain garden. Update the mitigation table as shown on the attached
markup.
3. Request and submit a new mitigation letter to reflect the entire amount of buffer mitigation credits
needed (i.e. 2,280)
4. The revised site plan is confusing because it shows the entire footprint of the home as an impact rather
than only the footprint outside the footprint of the previous home.
5. The site plan (labeled as stream survey — elizabethstn-611-stream.dwg) provided in the original
application most accurately depicts the information needed for the variance request. However, a
couple of corrections are needed to this drawing.
a. Add the driveway to show that the existing driveway will be utilized for the home. Is there no
sidewalk proposed from the existing driveway to the new home?
b. The voluntary planting proposed 10 feet wide along the stream channel is shown outside the lot
boundary. Do you have adjacent property owner permission? If not, please correct the drawing
to show replanting within the lot boundary only, provide the square footage of the area
proposed for replanting and the number of trees to be planted based on a rate of 260
trees/acre.
6. At #2 under Section D. Stormwater, list the square footage of the house footprint, which will be treated
by the proposed rain garden.
It is important to note that, if additional impacts are proposed (i.e. sidewalk), then the buffer impact table,
mitigation table and mitigation letter must be revised to reflect the additional impact. Please provide the
information above as soon as possible. I must have all of the materials for the meeting finalized and submitted
for posting by August 12, 2016 in order to make the September meeting.
Thanks,
Jennifer

2. Identify the square feet of impact to each zone of the riparian buffer that requires mitigation from the table above. Calculate
the amount of mitigation required.
For projects in the Goose Creek Watershed, list all riparian buffer impacts as Zone 1
and use Zone 1 multiplier.
3. Provide a description of how mitigation will be achieved at your site pursuant to the mitigation requirements of the applicable
river basin/watershed.
Applicant shall submit a landscape and revegetation plan that uses a mix of species regardless of whether less than 20 trees are
determined to be necessary on the subject parcel. Applicant shall use as a guideline that Unified Development Ordinance for the
City of Durham as its foundation and include any and all required elements per Title 15A NCAC 02B et seg., remedial measures
to maintain diffuse flow of runoff by dispersing concentrated flow, Applicant's plan is set forth in the attached Mitigation Plan
which includes a Planting Plan.
