This project is denied. 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. Provide a completed and signed DEQ registration statement. (Rev. 1) The DEQ permit for the tree cutting will be used. 2. Provide a signed certification. (Rev. 1) Comment addressed. 3. After approval, update the SWPPP with the stamped plans. (Rev. 1) The on -site SWPPP for the tree cutting can be updated/replaced. Please discuss with the County ESC Inspector. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. The PPP appears to be acceptable at this time. 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. This plan cannot be approved until the 4.73 Ibs/yr of nutrient credits have been purchased. Please contact Ana Kilmer prior to purchasing credits. Since this project drains to impacted streams, the credits will need to be purchased from the Ivy Creek or Rivanna River credit banks, since they are located in the same HUCB. [9VAC25-900-91.B] (Rev. 1) Comment addressed. Credits were purchased as part of tree cutting approval. Engineering Review Comments Page 2 of 3 2. A Stormwater Maintenance Agreement will be needed. Contact Ana Kilmer to begin this process. (Rev. 1) Comment addressed. 3. Revise grading so runoff is directed away from buildings. The grading slopes towards the buildings in several areas. (Rev. 1) Comment partially addressed. The grading should be revised behind the buildings between Private Alley 1 and the Amenity Area. 4. The grading in the laydown area next to the roundabout channelizes the runoff. Provide ditch designs and quantity control or revise to be sheet flow. (Rev. 1) Comment addressed. 5. Provide more details on the SWM facilities. Include views of the facilities at a larger scale with the various level 1 and level 2 requirements labelled. Also show the planting plans for all the facilities. (Rev. 1) Comment addressed. 6. Show the aquatic bench in the wet pond forebay (BMP Spec. 14 sect. 6.4). (Rev. 1) Comment addressed. 7. Show the forebays in the ED ponds (BMP Spec. 15 sect. 6.4). (Rev. 1) Comment addressed. 8. Include the riprap/permanent OP in the drainage easements. (Rev. 1) Comment addressed. 9. Show easements on the swales between pipe outlets and SWM facilities. (Rev. 1) Comment partially addressed. The easement should be extended from the pipe outfall on sheet C4.3. 10. Provide an exhibit (separate from the plans) that shows the proposed improvements overlaid with the removed stream buffer and the green space from the ZMA. (Rev. 1) Comment addressed. Revision 1 Comments 11. The SWM Facility easement on sheet C4.1 should be adjusted to include all of the access road. 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, 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. Include a note that additional measures may be required at the request of the County Inspector. (Rev. 1) Comment addressed. 2. The CWD must be released through a stabilized outlet. Include other measures along with the CWD or move/extend the CWD (VESCH 3.09). (Rev. 1) Comment addressed. 3. For diversions over 2% slope, show stabilization per VESCH 3.17 (VESCH 3.09). (Rev. 1) Comment addressed. 4. Show the SSF in the area of ST #1 on sheet C3.13 (the label is showing but not the linework). (Rev. 1) Comment addressed. 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 Review Comments Page 3 of 3 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. 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.
