This project is denied. The rationale is given in the comments below. The application may be resubmitted for approval if all of the items below are satisfactorily addressed. The VSMP application content requirements can be found in County Code section 17-401. A. Stormwater Pollution Prevention Plan (SWPPP) The SWPPP content requirements can be found in County Code section 17-405. A SWPPP must contain (1) a PPP, (2) an ESCP, (3) a SWMP, and (4) any TMDL measures necessary. 1. Please provide a signed registration statement (section 1) and signed certification (section 9). Rev. 1: The registration statement must be the current, 2019 registration statement. It can be found at this link: https://www.deg.virginia.gov/Portals/0/DEQ/Water/StormwaterM anagement/CGP%20ADA/CGP%20Registration%20Statement%202019 FI NAL 201904.pdf4ver=2019-05-01-163955-110 2. Insert an 11x17 sheet of your pollution prevention plan in section 6. Rev. 1: Comment addressed. 3. Provide template for inspection logs (section 12). Rev. 1: Comment addressed. 4. Provide the name of the person holding a certificate of competence who will be in charge of and responsible for carrying out the land disturbing activity once a contractor is selected. A Land Disturbance Permit cannot be issued until this information is provided. Rev. 1: Comment acknowledged. 5. Rev. 1: Section 9, signed certification, must be signed before the plan can be approved. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. No objections. Be sure to insert into approved plan into the SWPPP. C. Stormwater Management Plan (SWMP) Engineering Review Comments Page 2 of 4 VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This plan is disapproved, and the reasons are provided in the comments below. The stormwater management plan content requirements can be found in County Code section 17-403. 1. Please combine the Erosion Control Plan and the SWM Plan into one plan set. That plan should have the WPO201700022 number on it and have the title "VSMP Plan". Rev. 1: Comment addressed. 2. Nutrient credits must be purchased before plan can be approved. Contact Ana Kilmer before credits are purchased. Rev. 1: Comment not addressed. 3. Review the area of disturbance. Grading and disturbance appears to go outside the limits at the Greenbrier Dr. entrance and at the corner of Greenbrier Dr. & Westfield Rd. If disturbance during construction goes beyond the permitted limits, a stop work order may be issued until a DEQ permit is issued. Rev. 1: Comment addressed. 4. Information on Sheet C-405 was cut off. Please review the sheet layout and ensure all information is legible. Rev. 1: Comment addressed. 5. Ensure that all critical slopes and existing easements are shown on the plan. Rev. 1: Comment addressed. 6. Please provide the soil types (including their hydrologic soil groups) on the plan. Rev. 1: Comment addressed. 7. Provide permanent rip -rap design information for inlet of structure 8B-1 (or provide a paved flume or other measure to prevent erosion). Rev. 1: Comment addressed. 8. Provide a map showing the impervious area and managed turf area within the disturbed area used for the water quality calculations. Rev. 1: Comment addressed. 9. Provide the state -storage calculations/routings for the SWM pond as well as the emergency spillway design. Rev. 1: Comment addressed. 10. Provide a detail for the proposed retaining wall in the SWM pond.Rev. 1: Comment addressed. Please note that a building permit is necessary for retaining walls over 3 ft. in height. 11. Label the easement around the SWM pond, "SWM facility easement". This will need a SWM maintenance agreement as well as a deed/plat. Contract Ana Kilmer for the SWM agreement. Rev. 1: Comment not addressed. Plan cannot be approved until the SWM Agreement is recorded. The Final Site Plan cannot be approved until the plat/deed are recorded. 12. Storm pipe from 5A to 5 is labeled as sanitary. Also, the pipe from 5A to 5 is labeled as 15" in the detail, but 18" in the profile and the storm pipe calculations have a 113 and 8131. These appear to be mis-labeled. Please review and revise. Rev. 1: Comment addressed. 13. Label the strength class of the proposed storm pipes on the profile. Also, ensure that all utility crossings are shown. Rev. 1: Comment addressed. 14. Provide a map showing the drainage to each storm structure. Rev. 1: Comment addressed. 15. Storm pipe from 8B 1 to 8B must be in a drainage easement since it is carrying offsite water. Rev. 1: Comment addressed.

Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a meeting to discuss this review. Process; After approval, plans will need to be bonded. The bonding process is begun by submitting a bond estimate request form and fee to the Department of Community Development. One of the plan reviewers will prepare estimates and check parcel and easement information based on the approved plans. The County's Management Analyst will prepare bond agreement forms, which will need to be completed by the owner and submitted along with cash, certificates or sureties for the amounts specified. The agreements will need to be approved and signed by the County Attorney and County Engineer. This may take 2-4 weeks to obtain all the correct signatures and forms. Stormwater Management Facilities Maintenance agreements will also need to be completed and recorded. The County's Management Analyst or other staff will prepare the forms and check for ownership and signature information. The completed forms will need to be submitted along with court recording fees. After bonding and agreements are complete, county staff will need to enter project information in a DEQ database for state application processing. DEQ will review the application information based on local VSMP authority approval. At this time, the DEQ portion of the application fees will need to be paid directly to the state. For fastest processing, this is done electronically with the emails provided on the application. DEQ should notify applicants with instructions on how to pay fees. When DEQ approves the Engineering Review Comments Page 4 of 4 application, they will issue a permit coverage letter. This should be copied to the county. After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction conference. Applicants will need to complete the request for a pre -construction conference form, and pay the remainder of the application fee. The form identifies the contractor and responsible land disturber, and the fee remaining to be paid. This will be checked by county staff, and upon approval, a pre -construction conference will be scheduled with the County inspector. At the pre -construction conference, should everything proceed satisfactorily, a joint VSMP and grading permit will be issued by the County so that work may begin. County forms can be found on the county website forms center under engineering; htip://www.albemarle.org/deptfomis.asp?department=cdeng3Uo
