The. applicant must submit to Division of Water Quality (DWQ) three copies of the DWQ "General" Major Variance Application Form that describes how the following conditions of this variance will be met. If these conditions can not be met, an individual Major or Minor Variance from the Buffer Rules may be sought from the EMC. This "General" Major Variance shall expire on April 11, 2006 unless it is renewed before that time by the EMC. Conditions: 1. The residential lot must be located within one of the coastal counties as defined by the Coastal Area Management Act (CA'vIA). 2. Applicants must snow that they have met the requirements for a variance as specified in the buffer rules in "VARIANCES" (15A NCAC 2S .0233 9 a (iii) and I $A NCAC 2B .0259 9)(a i ()( ( )()(iii)j for the specific river basin where the impacts will occur. 3.

I I STORMWATER MANAGEMENT SUMMARY AND CALCULATIONS MARTIN RESIDENCE IMPROVEMENTS 2410 HARBOR ISLAND ROAD OLDE TOWNE SUBDIVISION NEW BERN, NORTH CAROLINA CRAVEN COUNTY ' PROJECT DESCRIPTION THE PROJECT IS LOCATED IN THE NEUSE RIVER BASIN, SPECIFICALLY AN ' UNNAMED EXCAVATED TRIBUTARY OF THE TRENT RIVER. THIS PROJECT PROPOSES DEVELOPMENT IN THE 50' RIPARIAN BUFFER AND THE 75' CAMA SETBACK AREA. ' THE MARTIN RESIDENCE WAS ORIGINALLY CONSTRUCTED IN THE EARLY 1970'S TIMEFRAME PRIOR TO THE ESTABLISHMENT OF THE NEUSE RIVER RIPARIAN ' BUFFER OR THE CAMA RULES. THE RESIDENTIAL STRUCTURE IS LOCATED AN AVERAGE DISTANCE OF 40'- 54' FROM THE BULKHEADED WATERFRONT WITH THE REMAINING AREA EXISTING AS PORCH AND WALKWAY AREAS. AN ' EXISTING SWIMMING POOL IS PRESENTLY LOCATED IN THE BUFFER AREA AS WELL AS WOODEN DECKS. THE OTHER AREAS ARE MAINTAINED AS DENSE ' GRASS LAWN AND LANDSCAPED AREAS. THE LOT HAS RELATIVELY FLAT TOPOGRAPHY. ' THE RESIDENCE IS CURRENTLY BEING RENOVATED TO UPDATE ITS APPEARANCE AND TO PRESERVE ITS VALUE. THE IMPROVEMENT PROPOSED WILL AFFECT BOTH THE NEUSE RIVER RIPARIAN BUFFER AND THE CAMA ' SETBACK AREA. AN ADDITION IS PROPOSED TO BE CONSTRUCTED ON THE EASTERN SIDE OF THE HOUSE. THE PROPOSED CONSTRUCTION IS OUTLINED ON THE ATTACHED PLAN. NEUSE BUFFER/CAMA IMPACTS ' THE PROPOSED CONSTRUCTION WILL AFFECT THE NEUSE RIVER RIPARIAN BUFFER AREAS AS FOLLOWS: RIPARIAN AREA EXISTING IMPERVIOUS AREA NEW IMPERVIOUS AREA 30' BUFFER AREA 0 SF 0 SF 50' BUFFER AREA 0 SF 218 SF 75' CAMA SETBACK 222 SF 282 SF ' THE TOTAL NEW PROPOSED IMPERVIOUS AREA WITHIN THE NEUSE RIVER RIPARIAN BUFFER AREA IS 218 SQUARE FEET. THE ADDITIONAL NEW ' IMPERVIOUS AREA IN THE 75' CAMA SETBACK TOTALS 282 SQUARE FEET. PROPOSED MITIGATION MITIGATION IS PROPOSED TO OFFSET THE IMPACT WITHIN THE SETBACK AREAS ' ASSOCIATED WITH THIS PROJECT. THE 218 SQUARE FEET OF PROPOSED NEUSE RIVER BUFFER AREA IMPACT IS PROPOSED TO BE OFFSET WITH A PAYMENT TO THE WETLANDS RESTORATION FUND OF $0.96/SQUARE FEET FOR A TOTAL OF ' $209.28. A TOTAL OF FIVE TREES WILL ALSO BE PLANTED ALONG THE WATERFRONT AREA. IN ADDITION, STORMWATER RUNOFF FROM THE NEW IMPERVIOUS AREAS WILL BE DIRECTED AWAY FROM THE WATERFRONT. ' STORMWATER INFILTRATION MEASURES TO SATISFY CAMA REQUIREMENTS WILL ALSO BE IMPLEMENTED AS OUTLINED BELOW. ' THE EXISTING LOT DEVELOPMENT EXCEEDS THE 30% BUILT-UPON AREA CRITERIA REQUIRING TREATMENT OF EXCESS STORMWATER RUNOFF. SINCE THE HOME WAS DEVELOPED PRIOR TO CAMA REGULATIONS, THERE ARE NO ' FORMAL STORMWATER TREATMENT MEASURES FOR THE SITE. TO MITIGATE THE ADDITIONAL STORMWATER RUNOFF ASSOCIATED WITH THIS PROJECT, STORMWATER COLLECTION AND TREATMENT MEASURES ARE PROPOSED FOR ' THE COLLECTION AND TREATMENT OF AN EQUAL AREA OF IMPERVIOUS SURFACE BEING ADDED TO THE SITE WITHIN THE 75' CAMA SETBACK AREA. ' ALL ROOF AREAS OF THE RESIDENCE WHICH SLOPE TOWARD THE ADJACENT WATER BODY WILL BE GUTTERED WITH THE RUNOFF DIRECTED TO A LOW INFILTRATION AREA IN THE FRONT YARD AREA OF THE LOT. A SMALLER ' INFILTRATION AREA WILL BE LOCATED AT THE EASTERN CORNER OF THE LOT TO COLLECT RUNOFF FROM THE REAR PORTION OF THE HOUSE ADDITION. THE STORMWATER TREATMENT SYSTEM IS DESIGNED TO COLLECT THE RUNOFF FROM THE 10-YEAR, 24-HOUR STORM (6.75 INCHES) WITH A CONSERVATIVE ALLOWANCE OF 1-INCH OF INFILTRATION OCCURRING DURING THE 24-HOUR STORM PERIOD. THE NET STORMWATER DETENTION VOLUME WILL HOLD A TOTAL OF 5.75 INCHES OF RUNOFF. THE IMPERVIOUS SURFACE AREAS FROM WHICH RUNOFF WILL BE COLLECTED INCLUDE THE FRONT AND REAR GABLE ROOF AREAS OF THE PROPOSED ADDITION (1,000 SQUARE FEET). 500 SQUARE FEET OF IMPERVIOUS AREA WILL DISCHARGE TO THE INFILTRATION AREA ON THE SOUTHERN SIDE OR REAR YARD AREA OF THE SITE. THE RESULTING RUNOFF VOLUME REQUIRING STORAGE WILL BE 240 CUBIC FEET. THE PROVIDED INFILTRATION AREA IS 480 SQUARE FEET IN SIZE. THE ' RESULTING STORAGE DEPTH IS 0.5'(6") WHICH IS SATISFACTORY TO BE CONTAINED WITHIN THE DESIGNED INFILTRATION AREA. ' 500 SQUARE FEET OF IMPERVIOUS AREA WILL DISCHARGE TO THE INFILTRATION AREA ON THE WESTERN SIDE OF THE LOT IN THE FRONT YARD AREA. THE ' RESULTING RUNOFF VOLUME REQUIRING STORAGE WILL BE 240 CUBIC FEET. THE PROVIDED INFILTRATION AREA IS 1,050 SQUARE FEET IN SIZE. THE RESULTING STORAGE DEPTH IS 0.23'(2.75") WHICH IS SATISFACTORY TO BE ' CONTAINED-IN THE DESIGNED INFILTRATION AREA. THE PROPOSED DESIGN IS CONSIDERED AN INNOVATIVE METHOD OF TREATING ' STORMWATER RUNOFF FOR THE PROJECT AND MEETS THE INTENT OF 7H.0209, PARAGRAPH E2 OF THE COASTAL AREA MANAGEMENT ACT. 11 _u June 5, 2002 AVOLIS ENGINEERING, P.A.
