Dir: 757-355-6640 Cell: 757-343-3307 From: Nelson, Christine [mailto:christine.nelson@ncdenr.gov] Sent: Tuesday, May 15, 2012 9:56 AM To: Sauro, Tom Subject: RE: request for additional info - Heroes Manor Tom, I understand the confusion as the planting plan in those two chapters do appear to be inconsistent. I don't know the basis for the difference only that the pond and wetland BMPs have two separate designs with different requirements. I have referred people to the wetland chapter when they are looking for a suggested lists of plants. Since this permit was originally issued, we have been asked to look more closely at the vegetated shelf planting plan to ensure it meets the requirements of the wet pond chapter. I cannot require the originally permitted side to meet the planting density in the wet pond, but the expanded side and the new pond will have to meet the requirements of the wet pond chapter. You can certainly use the 5' OC criteria for the larger shrubs and backfill with smaller plants to meet the density required by the wet pond chapter. As far as the inconsistencies between the two chapters, I would suggest you pass this up through the BMP manual comments link found on the BMP manual website: http://portal.ncdenr.org/web/wq/ws/su/bmp-manual/comment Sometimes the public will get a better response from those in charge of the BMP manual when bringing up comments like yours. Hope this helps.

I know that Chapter 9 is for Wetlands, but why have two conflicting planting requirements for basically the same thing? He also pointed out that the previous plans for BMP #1 were planted using the same math and if the expansion of BMP #1 were to have a different number of species, it will look uneven. I've highlighted the calculation that he used on page 9-18 (pdf page 18) for your reference. Can you see if this would be acceptable from DWQ for both the expansion of BMP #1 and BMP #2. I am working on trying to find another fountain manufacturer that has a 1/3 HP fountain now. Tom Sauro Kimley-Horn and Associates, Inc.

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 fountain detail for pond 2 on sheet CD503 says that a 1/2 HP fountain will be used even though the maximum allowable horsepower is 1/3 HP (based on permanent pool volume). Since this detail doesn't specify the option of a 1/3 HP fountain, this sheet can either be removed from the plan set or an updated sheet specifying a 113 HP fountain can be submitted. 2. Please revisit the shallow land planting density of the vegetated shelf for the ponds to ensure it meets the minimum planting density as required by Section 10.3.7 of the NC BMP manual. This section of the BMP manual requires a minimum of 50 plants per 200 square feet of shelf area or plants spaced 24" on center. 3. The express additional information fee has been waived for this request for additional information. 4. Please keep in mind that changing one number may change other numbers and require the calculations, supplements, and other supporting documentation to be updated. Verify all numbers are correct to ensure consistency in the application documents. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to May 21, 2012, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. Please note that a second significant request for additional information may result in the return of the project. If the project is returned, you will need to reschedule the project through the Express coordinator for the next available review date, and resubmit all of the required items, including the application fee.

This letter will address each comment through additional information, figures and attachments. The responses below are numbered to correspond with the comments contained in the May 8, 2012 letter (see attached). 1. Please see the attached calculations, BMP supplement forms and BMP O&M forms. The bottom of the pond elevations for BMP 1 and BMP 2 have been correctly stated to be the top elevation of the sediment cleanout as 4 and 13.5, respectively. 2. Please seethe attached BMP 2 supplement form. The SA/DA ratio has been revised to be consistent with the ratio presented in the calculations. 3. Please see page 3 of the attached BMP 2 O&M form which has been updated per the calculations. 4. Please see the attached post -development drainage area map. The overall drainage areas include the area of the ponds and the drainage area divides have been modified for clarity. 5. Please see the attached plans and exhibits which have been revised to show the location of the 50' buffer. 6. Please see the attached plans and exhibits which have been revised to meet the horsepower guidance for the pond fountains. There is no longer an additional fountain proposed for BMP 1. Therefore the proposed fountain horsepower for BMP I and BMP 2 are 3hp and 1/3hp, respectively. 7. Please see attached plan sheet CD504. The level spreader detail has been revised to show the appropriate amount of rip rap per the design manual. s Suite 500 4500 Main Street Virginia Beach, Virginia 23462 �, VED MAY 1 1 L012 TEL 757 213 8600 FAX 757 213 8601 ❑�� Kimley-Hom _ and Associates, Inc. Name, Date, Page 2 8. Please see the attached planting plan sheets. The plant density for the BMP vegetated shelf has been revisited to meet the minimum requirements of the NCDENR Stormwater BMP manual. An additional species of herbaceous shallow water plant has been added to the pallet to meet the minimum required number of plant species. Calculations have been added to the BMP plant schedules on sheet CP-505 to demonstrate the number of plants required per type for each BMP. Total plants provided as well as the percentage of each plant specified has also been added to the schedule for clarification. 9. The additional information review fee has been waived. 10. Please see attached stormwater calculations and plans, both have been reviewed for consistency and accuracy. If you have any questions or require additional information, please contact me at (757) 355- 6645 or email me at erin.burdick@kimley-horn.com. We look forward to hearing from you.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: On page 1 of Appendix D and E, the elevation of the bottom of the ponds appears to be presented differently. For pond 1, the elevation listed appears to be top elevation of the sediment cleanout while for pond 2, the elevation listed appears to be the bottom elevation of the sediment cleanout. Additionally, please ensure that the elevations for the bottom of the pond (top of the sediment cleanout elevation) are consistent throughout the application documents. For Pond 1, the elevation for the bottom of the pond is identified in the various application documents as follows: Source: Pond Bottom Supplement 4 Operation & Maintenance 3.5 Calculations (pg 1 of A endix D 3.5 BMP detail plan sheet 4 2. For pond 2, the SA/DA ratio listed on the supplement is not consistent with the SA/DA ratio presented in the calculations. Please ensure the information is consistent. 3. Please update page 3 of the Operation & Maintenance agreement for pond 2. The elevations listed appear to be from an old design. 4. Please confirm that the drainage areas include the area of the pond. The provided drainage area map appears to identify the ponds as a separate drainage area leading one to believe that the ponds are excluded from the drainage area used to design the ponds. It would be best to update the drainage area maps to not divide the BMPs into separate drainage areas.

Please label the 50' buffer along the surface waters on the pond detail and site plans. 6. Please revise the fountain details on plan sheet CD503 to meet the horsepower guidance available in the NC BMP manual. Based on the provided permanent pool volume, the largest fountain currently allowed for pond 1 and 2 are 3 hp and 1/3 hp, respectively. 7. Please revisit the level spreader detail presented on plan sheet CD504 to ensure it meets the design specified in the NC BMP Manual. For instance, the width of the riprap is currently set at 10'; however the manual specifies only 3' is needed. 8. Please revisit the planting density of the vegetated shelf for the ponds to ensure it meets the minimum density required by Section 10.3.7 of the NC BMP manual. 9.
