On February 10, 2016, the Division of Water Resources (Division) received your application dated
February 101, 2016, requesting Major Variance from the Division for the subject project. The
Division has determined that your application is incomplete and cannot be processed. The
appIlication is on -hold until all of the following information is received:
1. In the buffer impact table of your application, impacts from the, proposed rain gardens
are Iisted in the Zone 2 column; however, the rain gardens are located in Zone 1,
Constructing a rain garden within the buffer is an activity that is allowable with
mitigation. Mitigation for impacts to Zone 1 require a multiplier of 3 to determine the
amount of mitigation required. Zone 2 impacts require a multiplier of 1.5 to determine
the amount of mitigation required. Therefore, the amount of mitigation proposed does
not comply with the rule. You will need to either request additional mitigation to cover
the amount required by the Zone 1 multiplier or you request approval of an alternate
mitigatioin plan for the rain gardens portion of your project. If you prefer, we can request
a variance from the mitigation requirement for the rain gardens as part of the overall
variance request by offering your proposal to remove English ivy and plant woody species
within the buffer and adjacent to the stream channel as mitigation for these impacts.
Please provide a key of the plant species on the site plan that are proposed to be planted
within the riparian buffer. [15A NCAC 02B .0233(10)]
2. The following comments are provided regarding the proposed rain gardens. [15A NCAC
