Total Buffer Impact for Project 1450 square feet
The project shall be constructed in accordance with your application dated received February 14 2012 with
additional information dated received February 15 2012 This approval is valid for the Jordan Lake Riparian Buffer
Rules (15A NCAC 213 0267) In addition you should acquire any other federal state or local permits before you
proceed with your project including (but not limited to) Sediment and Erosion Control Non Discharge and Water
Supply Watershed regulations This approval expires five years from the date it was issued
This approval is valid solely for the purpose and design described in your application (unless modified below)
Should your project change you must notify the NCD WQ and submit a new application If the property is sold the
new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying
with all the conditions If total wetland fills for this project (now or in the future) exceed one acre or of total
impacts to streams (now or in the future) exceed 150 linear feet compensatory mitigation may be required as
described in 15A NCAC 2H 0506 (h) (6) and (7) Additional buffer impacts may require compensatory mitigation
