Main St. Charlottesville, VA A22902 [alan@alanfranklinpe.com ] [ afranklin(ae waterstreetstudio.net ] Merrie Farm LLC / P.O. Box 70, Keswick, VA 22947 [ evpellvCd�gmmlxom ] 24 Aug 2020 30 Sep 2020 John Anderson 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 for reasons listed 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. Sec. 1, Registration Statement a. Sec. W.E. /MS4: Leave blank since Merrie Mill Farm lies outside Albemarle County MS4. b. Sec. W.F. /Common Plan: checkbox, please check `No.' 2. 6.A.: Revise PPP Exhibit to include: a. Rain gauge location. b. On -site fuel storage for construction grading equipment, if proposed (better to show and not need, than to need and not show). Provide secondary (berm) containment with impermeable liner with volume sufficient to accommodate volume of stored fuel + 10-yr. storm event (vol.) x 1.1. c. Recommend relocate concrete washout location since it appears remote from concrete placement location, and occupies area that will be graded and paved. Recommend area near PCE. d. Limits of Disturbance listed as 40,000 SF while plan indicates LOD =1.54 Ac. Revise for consistency. 3. Include reference to WP02020-00040 in SWPPP title. 4. Provide complete tel. # for John Divert /Shelter Assoc., on SWPPP cover page. B. Pollution Prevention Plan (PPP) — See item 2 above. The PPP content requirements can be found in County Code section 17-404. C. Stormwater Management Plan (SWMP) — Note: comments below include ESC plan review comments. VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This plan is disapproved for reasons listed below. The stormwater management plan content requirements can be found in County Code section 17-403. 1. Revise EC 100 to include: a. Reference to WF b. Project tax map parcel number. 2. Provide a new existing conditions plan sheet, that includes, or shows: a. Project site TMP, with ownership information, incl DB-PG reference. Engineering Review Comments Page 2 of 3 b. Property lines, with adjacent property ownership information (see, 2.a., above). c. Distance from bend in paved drive to Louisa Road (SR 22). d. Mapped floodplain (highlight, GIS image, below). e. Water Protection Ordinance (stream) buffers. f Existing pond (image, below). 9 3. SW100 a. Show tasting room roof (downspout pipe) discharge to level spreader/s, or similar, to transition concentrated roof runoff to sheet flow, else revise SW 100 to demonstrate post -developed compliance with 9VAC25-870-66, stormwater quantity. i. Indicate length and location of (each) ELS. ii. Ensure downslope gradient is consistent with /meets requirements listed in VA DEQ Stormwater Design Specification No. 2, Table 2.2. b. Provide pre- /post -developed drainage maps. c. Revise VaRRM.xIs if LOD =1.54 Ac. rather than 0.92 Ac. d. Note: Engineering requires SWM Maintenance Agreements for ELSs for all sites other than single family residences. Engineering does not however, require an easement plat or SWM facility deed of dedication (as in the past) for sites unless a site plan or final subdivision plat is required. This site fits that category (Agricultural use /no subdivision, no Site Plan), and will not require an easement plat or deed for ELS/s that may be required (appear to be required) to ensure post - developed sheet flow, especially from venue tasting room roof. 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 disapproved for reasons listed, below. The erosion control plan content requirements can be found in County Code section 17-402. 1. EC101 a. Maximum slope length above SF is 100'. In several locations SF upslope limit is exceeded. Provide alternate ESC measures, diversion dikes diverting runoff to traps, for example. It appears unlikely a 1.54 Ac. disturbance in close proximity to floodplain and stream buffers would not require one or more sediment traps. Engineering Review Comments Page 3 of 3 b. There are separate, inconsistent references in SWPPP and plan to 0.92 Ac., 40,000 SF, and 1.54 Ac. LOD. Please check LOD, and revise LOD references in SWPPP and plan for consistency. c. Eliminate SF if not parallel (or nearly parallel) with terrain contours. Provide alternate temporary ESC measures, as needed. SF is installed cross -contour, parallel with terrain contours. 2. EC-102: Indicate locations of soil blanket stabilization, wherever slopes are steeper than 3:1. 3. EC-103: Ref. SWM Plan comment /item #3, above, and provide level spreader (ELS) detail. The VSMP permit application and all plans may be digitally resubmitted for approval when all comments have been satisfactorily addressed. Please provide digital version of revised plan /SWPPP with a completed application form. 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 24 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. • If nutrient credit purchase is required (0.83 lb. purchase is proposed), purchase documents must be executed prior to county issuance of a grading permit. After bonding and agreements are complete, county staff will need to enter project information in a DEQ database (if LOD >1.0 Ac.) 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 emads provided on the application (SWPPP Registration Statement). 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, the County can hold a pre -construction conference. Applicants must request a pre - construction conference (complete form) and pay any remaining application fee. The form identifies the contractor and responsible land disturber, and 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 grading permit will be issued by the County so that work may begin. County forms can be found on the county website under engineering applications at: httos: //www.albemarle. ore/govemmenVcommunity-develoomenVaooly-for/engineering-applications Please Note: Albemarle County website was redesigned/relaunched 8/10/2020.
