[Justin@shimp-engineering.com] Owner or rep.: Peter Stoudt [peterstoudt(a�earthlink.net] Alice Handy[alicehandy2(a�gmail.com] Ned Ormsby [ned@lithicconstruction.com] Plan received date: 18 Feb 2020 Rev. 1 received: 01 April 2020 Date of comments: 16 March 2020 Rev. 1 comments: 28 April 2020 Reviewers: Emily Cox 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. What is the correct title for this project? It was listed as Lithic property, Stoudt property and Lithic Stoudt Handy on all different documents. Rev. 1: Comment addressed. 2. Rev. 1: Section 9, signed certification, must be signed. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. Please double check the PPP provided in the SWPPP book to ensure all items apply to this site. Also, a lot of items note that they are shown on the plan, but they are not currently shown on the plan. Rev. 1: Comment addressed. 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. Proposed open space should be labeled as "SWM Forest & Open Space." Any Forest and Open Space used in the VRRM worksheet will need to be shown on an Easement Plat and labeled as 'SWM Forest and Open Space'. Land disturbance permit cannot be issued until the plat is Engineering Review Comments Page 2 of 3 recorded. Easement plat application can be found here: http://www.albemarle.org/upload/images/forms center/departm ents/Community Development/forms/Subdivision Applications/E asement Plat & Checklist . pdf Rev. 1: Comment response says credits will be purchased, but section 5 of the SWPPP says that open space will be used and Sheet C5 and calculations packet narrative says that nutrient reduction will be achieved by the vegetated filter strip. Please clarify. 2. The following note will need to be placed on both the VSMP plan and the Easement Plat:"The SWM Forest and Open Space Easement is subject to the guidance set forth by DEQ in the Virginia Stormwater Management Program. The areas will remain undisturbed in a natural, vegetated state, except for activities as approved by the local program authority, such as forest management, control of invasive species, replanting and revegetating, passive recreation (e.g., trails), and limited bush hogging to maintain desired vegetative community (but no more than four times a year)." Rev. 1: Comment response says credits will be purchased, but section 5 of the SWPPP says that open space will be used and Sheet C5 and calculations packet narrative says that nutrient reduction will be achieved by the vegetated filter strip. Please clarify. 3. [Sheet C2 and cover sheet] Existing contour elevations do not appear to match County GIS. Please check the information and provide a date the topographic information was obtained or field verified. Rev. 1: Comment not addressed. County GIS shows elevation of 612 surrounding the house, your contours are in the 400's. 4. [Sheet C2] Please show the 100ft WPO buffer. The stream is shown. Rev. 1: Comment addressed. 5. Rev. 1: Sheet C2 should not show the proposed buffer since it is existing conditions. 6. Rev. 1: Ensure appropriate grading is used and shown for drainage area maps (for example, proposed grades should be used for the post-dev drainage area maps. 7. Rev. 1: Provide all required design information for the vegetated filter strip per Practice 2 in the BMP clearing house: https : / /www. swbmp . vwrrc . vt . edu/ 8. Rev. 1: Ensure maintenance requirements for the filter strip are shown on the plans. D. 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. [Sheet C3] The landscape buffer is outside the limits of disturbance. Will this land need to be cleared for planting? Please add a note so the contractor knows not to disturb the area. Rev. 1: Comment addressed. 2. [Sheet C5] Please provide the paved wash rack detail from the design standards manual, page 8: http://www.albemarle.org/upload/images/forms center/departments/community_ development/for ms/design_ standards_ manual/Albemarle County_Design_ Standards_Manual _2015-04- 25_draft.pdf Ensure there is a place for the wash rack water to settle. Rev. 1: Comment addressed. 3. [Sheet C6] Please show that the DA to the silt fence complies with requirement of/4 ac per 100 ft of silt fence. Rev. 1: Comment not addressed. Plan shows 0.31acres/100 ft, when only 0.25 (1/4 ac per 100 ft) acres is allowed. Based on the silt fence length of 255 ft, only 0.64 acres of drainage is allowed. There is 0.78 currently shown. 4. [Sheet C6] Ensure the diversion has an adequate outfall. VESCH 3.12 says, Outlet Diversions shall have adequate outlets which will convey concentrated runoff without erosion. Acceptable outlets include STORMWATER CONVEYANCE CHANNEL (Std. & Spec. 3.17); LEVEL Engineering Review Comments Page 3 of 3 SPREADER (Std. & Spec. 3.21); OUTLET PROTECTION (Std. & Spec. 3.18); and PAVED FLUME (Std. & Spec. 3.16). Rev. 1: Comment not addressed. Silt fence cannot be the outfall of a diversion channel. 5. Rev. 1: VDOT permission will be necessary for the construction entrance. 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.
