be granted by the Stormwater Administrator if the development meets the following requirement: The proposed now
development appropriately uses the parcel's total remaining total impervious area to the extent practical to
convey and control the stormwater runoff, and it is demonstrated, to the satisfaction of the Stormwater Vj
Administrator, that no damage to public or private propefffes, including to the City's stormwater facilities and to the
quality ofthe public waters, will be caused by granting of the variance. Is this requirement met for the proposed
development?
Yes — A flow control BMP is not required for this development but the New Bern Stormwater

Calculating Total Nitrogen Export from New Development
For the purposes of the City of New Bern Stormwater Program, new development shall be defined as to include the Wo
following:
Any activity that disturbs greater than one-half acre of land in order to establish, expand or modify a single
family or duplex residential development or a recreational facility.
New development shall NOT include agriculture, mining or forestry activities, land disturbance is defined as
grubbing, stump removal and/or grading.
Property owners that can demonstrate that they have vested rights as of the effective date of the New Bern
Stormwater Ordinance (expected April 10, 2001) will not be subject to the requirements for new development,
Vested rights may be based on at least one of the following criteria:
(a) substantial expenditures of resources (time, labor, money) based on a good faith reliance upon having received
a valid local government approval to proceed with the project, or
(b) having an outstanding valid building permit in compliance with G.S. 153A-3"A or G.S. 160A-385.1, or
(c) having an approved site specific or phased development plan in compliance with G.S. 153A-344.1 or G.S.
160A-385.1.
Projects that require a state permit, such as landfills, NPDES wastewater discharges, land application of residuals
and road construction activities shall be considered to have vested rights if a state permit was issued prior to the
effective date of the New Bern Stormwater Ordinance.
The rule requires that all new developments achieve a nitrogen export of less than or equal to 3.6 pounds per acre
Per year. If the development contributes greater than 3.6 Ibs/aclyr of nitrogen, then the options shown in Table 1
are available based on whether the development is residential or non-residential. 4

Step 1: Determine area for each type of land use and enter in Column (2)_
Step 2: Total the areas for each type of land use and enter at the bottom of Column (2)_
Step 3: Multiply the areas in Column (2) by the Total Nitrogen (TN) export coefficients in Column (3) and enter in
Column (4).
Step 4: Total the TN exports for each type of land use and enter at the bottom of Column (4).
Step 5: Determine the export coefficient for site by dividing the total TN export from uses at the bottom of Coiumn
