This project is approved/disapproved. The rationale is given in the comments below. 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. SWPPP will need to be updated to include the final approved plans. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. No Comment. C. Stormwater Management Plan (SWMP) 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. Since this plan is for the establishment of a single family dwelling unit, according to County Code 17-403-B, an agreement in lieu of a stormwater management plan can be used. The conditions listed on the agreement must still be met, but your water quality and VRRM requirements (forest & open space easement) may be removed. The level spreaders must remain to address the concentrated flow. This is the agreement: https://www.a I bemarle.org/home/showpubl isheddocument/2710/6375390452401700 00 Please fill it out and submit with your next submission. 2. An easement is not required for the level spreaders, however a SWM facility maintenance agreement will be necessary before this plan can be approved. Please contact Ana Kilmer [akilmer@albemarle.org or 434-296-5832 ext 3246) in our office to complete that process. 3. Please add the WPO number to the cover sheet, W130202100056. 4. Ensure no proposed slopes are steeper than 2:1. Area before level spreader B appears to be steeper. Engineering Review Comments Page 2 of 3 5. Please show the 25 year storm for the culvert calculations. 6. Ensure that all criteria are met for the level spreaders per this spec: https://swbmpvwrrc.wp.prod.es.cloud.vt.ed u/wp- content/uploads/2018/07/BMP Spec No 2 SHEET FLOW.pdf Specifically, please show downstream of the level spreaders (maximum slopes and possible stabilization measures necessary). D. Erosion and Sediment Control Plan (ESCP) Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. This plan is approved/disapproved, and the reasons are provided in the comments below. The erosion control plan content requirements can be found in County Code section 17-402. 1. Please add the county erosion control notes to your plans: https://www.a I bemarle.org/home/showpubl isheddocument/ 1262/6373213252553300 00 2. Please provide the paved construction entrance detail with a wash rack from page 8 of the design standards manual: https://www.albemarle.org/Home/ShowDocument?id=270 Ensure the wash water has a place to drain. 3. Please show dust control on all E&S sheets. 4. Please show a construction staging and parking area. The VSMP permit application and all plans may be resubmitted for approval when all comments have been satisfactorily addressed. For re -submittals please provide 2 copies of the complete permit package with a completed application form. Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a meeting to discuss this review. Process: After approval, erosion and sediment control and stormwater management improvements must be bonded. The bonding process begins when the plan is approved, and the applicant submits a bond estimate request form and fee to the Department of Community Development. A plan reviewer 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 to the County, who will record the agreement. Engineering Review Comments Page 3 of 3 After bonding and agreements are complete, county staff enters project information in a DEQ database for state application processing, if a DEQ permit is required. DEQ reviews 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 application, they will issue a permit coverage letter, which must be posted at the construction site. After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction conference. Applicants must 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.
