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. Provide a signed Registration Form. (Rev. 1) Comment addressed. 2. Provide a signed Certification. (Rev. 1) Comment addressed. 3. Include the information on impaired waters in section 7. (Rev. 1) Comment addressed. Revision 1 comments 4. The proposed area of disturbance is listed differently throughout the SWPPP and plans (12.88 ac. on the Registration Statement, 15.58 ac. in the Nature of Activity, 15.04 ac. in the VRRM not including forest and open space). Please revise to have the same acreage. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. The PPP is 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. Engineering Review Comments Page 2 of 3 1. A FDP permit application and a Flood Study will need to be submitted and approved [18.30.3.12, 18.30.3.13]. (Rev. 1) Comment not addressed. 2. This plan cannot be approved until the 1.84 Wyr 1.38 lb/yr of nutrient credits have been purchased. Please contact Ana Kilmer prior to purchasing credits. (Rev. 1) Comment not addressed. 3. Please contact Ana Kilmer to complete a Stormwater Management Facilities Maintenance agreement. (Rev. 1) Comment addressed, the agreement will need to be recorded prior to approval. 4. The Forest and Open Space Easement, SWM Facility easements and Mitigation easement will need to be shown on the Final Plat and a Deed of Dedication will need to be signed and recorded for these easement. The Deed will filled out by the County and forwarded to the applicant when the plat is nearing approval. (Rev. 1) Response noted. 5. Show and label all proposed easements on the plans, including facility and access easements. (Rev. 1) Comment partially addressed. Revise the easement linetype so it shows up clearer. Show easements on the entrance culvert, structure 600 on the entrance road, and on the structures/pipes in the parking lots of the proposed apartment buildings (others may not be listed). 6. Clearly show and label how the bioretention will be accessed for maintenance. (Rev. 1) Comment partially addressed. The maximum slope for a grassed access is 20%, please revise. [Design Standards Manual] 7. Include the bioretention maintenance and inspection schedules from DEQ BMP Spec. 9 on the plans. (Rev. 1) Comment addressed. 8. Include the planting plans for the bioretention. (Rev. 1) Comment partially addressed. Only one biofilter shows any plantings on the landscape plan. Provide separate details/tables for the biofilter plantings following the requirements in DEQ BMP Spec. 9 sections 6.8 and 6.9. 9. Provide the routing calculations for the bioretention. (Rev. 1) Comment addressed. 10. Show and label the pre-treatment requirements for the level 2 bioretention on the plans. (Rev. 1) Comment partially addressed. Show and label both of the two required pre -treatments for each Level 2 biofilter. Include the size of the pre-treatment cells. [DEQ BMP Spec. 9, Table 9.3 and Section 6.4] 11. Provide more detail on the path through bioretention 2. (Rev. 1) Comment addressed. 12. Include the County As -built requirements on the plans. (Rev. 1) Comment not addressed. Include the VSMP As -built requirements. 13. On sheet C6.0, include a breakdown of the proposed and conceptual impervious areas in each biofilter drainage area. (Rev. 1) Comment addressed 14. Show more detail for the outfall into the stream. Include the stream banks, as it will need to outfall directly in the stream to not use energy balance. Include a drainage area map for the stream to show the 1% is being met. (Rev. 1) The provided DA map appears to be incorrect. Areas are included that enter the stream below the proposed outfall and areas that drain to the other side of the Interstate. I've attached a printout from County GIS showing the drainage area at the pipe outfall. 15. Contact the Army Corp and provide correspondence allowing the outfall into the stream. (Rev. 1) Comment not addressed, response noted. D. Erosion and Sediment Control Plan (ESOP) Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESOP. This plan is 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. Revision 1 comments Engineering Review Comments Page 3 of 3 2. Provide a sediment trap for the grading on the northeast side of the entrance. The final grading should also be revised to direct the runoff to the culvert instead of having channelized runoff flowing into the road. 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, 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 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.
