[email] Albemarle County, c/o Frank Pohl [fpohl @albemarle.org] 10 Sep 2014 24 Sep 2014 Max Greene, Glenn Brooks County Code section 17 -410 and Virginia Code §62.1- 44.15:34 requires the VSMP authority to act on any VSMP permit by issuing a project approval or denial. 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 ESOP, (3) a SWMP, and (4) any TMDL measures necessary. 1. A generic SWPPP document was provided, but it was unsigned and incomplete, including a blank registration statement. Please complete all documents. A. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17 -404. 1. A PPP was not found. B. 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. Please provide a narrative to explain the purpose and methods of this plan. As there is no removal requirement for the project itself, which appears to be a basin enhancement, some explanation is needed. 2. The drainage area to the basin needs more explanation. Please show all the pipe and conveyance systems which direct runoff to the basin. It has been our understanding that many of the developments across Hillsdale Drive are not draining to this basin. 3. There is not enough information provided to check the VRRM input. Provide soils data on the drainage maps. 4. There is not enough information provided to check the wetland design. Provide a complete check of Table 13.2 criteria from the specification. Engineering Review Comments Page 2 of 3 5. There appears to be some sort of channelization and flow splitting in the basin, but there were no details or computations found for this feature. C. Erosion and Sediment Control Plan (ESOP) Virginia Code §62.1- 44.15:55 requires the VESCP authority to approve or disapprove an ESCP. 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. Silt fence will not keep sediment laden waters from going downstream when the basin fills. A dewatering strategy is needed, along with a temporary riser on the culvert structure. It appears the entire area will act as a sediment basin. 2. Increase the limits to include work noted outside the limits on the plan. 3. Draw realistic limits of disturbance. The hard corners are not realistic, and room is needed to work outside the wetlands. 4. The CE is shown over a steep slope, with a turn. Show grading to accomplish this. 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 Engineering Review Comments Page 3 of 3 work may begin.
