(2s— 1 Re: Additional Information Request for Eckerd's #2166R, Stormwater Project No. SW8 980531 Dear Linda, Pursuant requests cited in your letter dated July 9, 1998 we have revised our plan and calculations. 1 will address each item in the order noted in the aforementioned letter. 1. The pond dimensions have now been revised to provide 4422 square feet exceeding the required surface area of 3810 square feet at the 34.7 permanent pool elevation. The vegetated shelf is now shown beginning one foot below the permanent pool and ending at the permanent pool elevation. 2. The orifice has been resized to insure drawdown of the required storage volume in not less than 2 days. (See detail sheet) 3. There are no wetlands on this site. A note has been added on the plan to this effect. 4. The pond is now located in a access/drainage easement. I hope that this addresses all of your initial concerns. Upon review of the additional information please call me such that we may pick up any more requests or the permit. We wish to hand deliver a copy to the city in order to expediate the building permit. Thank You, ames H.

Stroud Engineering 3961-A Market Street Wilmington, NC 28403 Subject: ACKNOWLEDGEMENT OF RECEIPT AND REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SW8 980531 Eckerd's //2166R New Hanover County Dear Mr. Fentress: The Wilmington Regional Office received a Stormwater Management Permit Application for Eckerd's 1/2166R on May 14, 1998. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. The pond dimensions shown do not provide the needed permanent pool surface area. My calculation shows that 3,590 square feet is provided at 34.7, 5,037 square feet is provided at 35.5, and 5,566 square feet is provided at 35.65. Please verify and provide additional area at 34.7 to meet the required 3.,810 square feet. In order to facilitate this, the 6:1 vegetated shelf may be relocated completely under the permanent pool.This is the preferred design. 2. Based on the pond dimensions provided, my calculation of the volume indicates that the 1.25" orifice specified is too large for the volume stored between 34.7 and 35.65. Drawdown is occurring in less than 2 days. It is possible that by increasing the surface area at 34.7, the volume will increase sufficiently to allow the use of the 1.25". 3. Delineate all wetlands on site, or note on the plans that none exist. 5. Locate the pond in an access/drainage easement. 127 Cardinal Dr.Ext.,Wilmington,North Carolina 28405 Telephone 910-395-3900 FAX 910-350-2004 An Equal Opportunity Affirmative Action Employer 50% recycled/10% post-consumer paper Mr. Fentress July 9, 1998 Stormwater Project No. SW8 980531 ---------------------------------------------- Please note that this request for additional information is in response to a preliminary review.

Monthly, or after every ninoff producing rainfall event, whichever comes first: A. Inspect the trash rack; remove accumulated debris, repair/replace if it is not functioning. B. Inspect and clear the orifice, of any obstructions. If a pump is used as the drawdown mechanism, pump operation will be checked. A log of test runs of the pump will be kept on site and made available to DBM personnel upon request. C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair eroded areas before the next rainfall event. D. If the pond is operated with a vegetated filter, the filter will be checked for sediment accumulation, trash accumulation, erosion and proper operation of the flow spreader mechanism. Repairs/cleaning will be done as necessary. II. Quarterly: A. Inspect the collection system (ie. catch basins, piping, grassed swales) for proper fimctioning. Accumulated trash will be cleared from basin grates, basin bottoms, and piping will be checked for obstructions and cleared as required. B. Pond inlet pipes will be checked for undercutting. Riprap or other energy dissipation structures will be replaced, and broken pipes will be repaired. M. Semi-annually: A. Accumulated sediment from the bottom of the outlet structure will be removed. B. The forebay depth will be checked at various points. Sediment removal is required when the depth is reduced to 75% of the original forebay design depth of 4 1. C. Grassed swales, including the vegetated filter if applicable, will be reseeded twice a year as necessary. W STORM ATER E C E I V E MAY 141998 D M�-nGe- R-e -- D E M PROJ N POND MAINTENANCE REQUIREMENTS PAGE 2 --------------------------------------------------------- IV. Annually: A. The pond depth will be checked at various points. Sediment removal is required when the depth is reduced to 75% of the original design depth or Y, whichever is greater. Design depth is 5.0 ', measured vertically from the orifice down to the pond's bottom. Sediment must be removed to at least the original design depth. V. General: A. Mowing of the side slopes will be accomplished according to the season. Maximum grass height will be 6". B. Cattails are encouraged along the pond perimeter, however they will be removed when they cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of the growing season, in November. Environmentally sensitive chemical for use in killing cattails can also be used. Contact your nearest Agricultural Extension Agent. C. The orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not accomplished in that time, the orifice will be replaced with a larger or smaller orifice. Slow drawdown may be attributed to a clogged system. The source of the clogging.will be found and eliminated. D. All components of the detention pond system will be kept in good working order. Repair or replacement components will meet the original design specifications as per the approved stormwater plan. If previously approved components are determined to be ineffective, the component must be redesigned and/or replaced. VI. Special Requirements: I, �i hereby acknowledge that I am the financially (please print or type 6ine clearly) responsible party for maintenance of this detention pond. I will be responsible for the performance of the maintenance as outlined above, as part of the Stormwater Management Permit received for this project.

Objective: Design a stormwater detention pond system to satisfy both the City and the State stormwater detention requirements. 2. Site Specifics: Site consists of 1.8 acres located between 16th and 17th Street and fronting Dawson Street. Site is presently developed as a Dairy Queen and a Wachovia Bank. As existing the site is approximately ninety percent impervious. As proposed the site will be sixty-eight percent impervious. 3. Design Constraints: Both the City and the State require that this site be viewed as if presently undeveloped.There is no consideration given for redevelopment.The site will have to meet the regulations just like any new development. The most practical outlet for the site will mandate the site grading requirements. 4. Itinerary: The State stormwater requirements will be calculated and designed first. Then the City requirements will be evaluated. JOB STROUD ENGINEERING, P.A.

FENTRESS,JR. C--) 9E�t) DATE EROSION CONTROL PLAN ECKERD STORE 2166R A. GENERAL 1. Description of Work The work proposed includes disturbing 1.8 acres of soil to construct a Drug Store. 2. Description of Site The site is 1.80 acres located in the southeastern quadrant of the intersection of Dawson and Seventeenth Streets in Wilmington,New Hanover County,North Carolina. According to the New Hanover County Soil Survey, soils on the site consists of Leon-Urban Land Complex Soils. These soils are sandy with a high rate of percolation. Runoff from the site is currently routed to catch basins(maintained by the City of Wilmington) in the Rights-of- Way of Dawson, Sixteenth, and Seventeenth Streets. Post development runoff will be routed to an on-site stormwater detention for sediment removal before release to the City's stormwater system. 3. Purpose of Land Disturbing Activity The proposed activity is to facilitate construction of the pond, utilities, and buildings on the property. 4. Method of Runoff Calculations The rational formula was used to calculate the pre-development and post development runoff rates. The runoff coefficient for the pre-development condition was assumed to be 0.9 and for the post-development condition a coefficient of 0.8 was used. Pre-development Rate Q= C I A where C = 0.9 I= 7.5 in. A= 1.8 ac. Q = 12.2 cfs Post-development Rate Q = CIA where C = 0.8 I = 7.5 in. A = 1.8 ac. Q = 10.8 cfs EROSION CONTROL PLAN ECKERD STORE 2166R 5. SEQUENCE OF ACTIVITIES The site will first be cleared of existing buildings and structures. The owner will then construct as shown on the attached site plan. 6. REVEGETATION OF DISTURBED SOILS All disturbed, exposed soils shall be stabilized in accordance with the attached seeding schedules within thirty days of the initial disturbance.
