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. Appears adequately addressed at this time. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17 -404. 1. Appears adequately addressed 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. Gabion Basket is not approved as replacement for standard outlet structure for basin. Excavation of dam for pipe installation is approximately the same as for gabion basket, however gabion basket after installation will have "piping" along sides of excavated area which could lead to a dam failure. The soil around a pipe can be compacted with less chance of "piping" around structure. A concrete cradle could be installed for better compaction around pipe. 2. VRRM Spread sheet was not found in submittal package. Please submit VRRM Spread sheet for SWM review. D. Erosion and Sediment Control Plan (ESCP) Virginia Code §62.1- 44.15:55 requires the VESCP authority to approve or disapprove an ESCP. Engineering Review Comments Page 2 of 3 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. 1. Gabion Baskets are not approved for sediment basin outlet. See comment above. 2. Phase 3 sediment trap will require armoring across filled basin area until area is stabilized. 3. Silt fence is shown inside proposed grading on the Northeast side of the site and will need to be adjusted to protect all proposed grading. 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.
