Applicability of other laws and regulations; time limits on applicability of approved design criteria. A. Nothing in this chapter shall be construed as limiting the applicability of other laws and regulations, including, but not limited to, the CWA, Virginia Stormwater Management Act, Virginia Erosion and Sediment Control Law, and the Chesapeake Bay Preservation Act, except as provided in § 62.1-44.15:27 K of the Code of Virginia, and all applicable regulations adopted in accordance with those laws, or the ri deral agencies, state agencies, or local governments to impose more stringent technical criteria or oth requirements as allo ed by law. B. Land -disturbing activities that obtain an initial state per it or commence land turbance prior to July 1, 2014, shall be conducted in accordance with the Part II C (9yAC25-870-93 et seq.) technical criteria of this chapter. Such projects shall remain subject to the Part II C technical criteria for two additional state permit cycles. After such time, portions of the project not under construction shall become subject to any new technical criteria adopted by the board. C. Land -disturbing activities that obtain an initial state permit on or after July 1, 2014, shall be conducted in accordance with the Part II B (9VAC25-370-62 et seq.) technical criteria of this chapter, except as provided for in 9yAc2s-s7o-48. Land - disturbing activities conducted in accordance with the Part II B technical criteria shall remain subject to the Part II B technical criteria for two additional state permit cycles. After such time, portions of the project not under construction shall become subject to any new technical criteria adopted by the board. Review and revise SWM Narrative and design, as needed to meet stormwater quality requirements listed at 9VAC25-870-65, and stormwater quantity standards listed at 9VAC25-870-66. (Rev. 1) Addressed. Also, see SDP2005-00069 (FSP). Since existing on -site bioretention basin is relied upon for the current application, plan must reflect As -built conditions consistent with VA DEQ Stormwater Design Specification No. 9, Level 1 or Level 2. Specify which bioretention design level this plan intends to meet. An existing BMP built Engineering Review Comments Page 4 of 7 to plan design (approved 7/12/13) that pre -dates the VSMP program effective date of 7/1/14 must meet applicable quality and quantity design requirements. Grandfathering (9VAC25-870-48) or Applicability of Part IIC (9VAC25-870-47) does not apply. This is not an Amendment application to an approved VSMP plan. VARI00512 was terminated, July 2018. This is a new application subject to Part IIB technical criteria. (Rev. 1) Withdrawn /NA since project subject to Part IIC.

First sentence of WP001900018 SWM narrative: "Stormwater quantity for this site is handled and treated by the regional stormwater management basin below this site and the other commercial and industrial parcels in this development area." Provide supportive information on the `regional basin,' including (but not limited to): (Rev. 1) Withdrawn. Storm runoff routes to an onsite bioretention basin, which then discharges to an intermittent stream, which eventually reaches a regional stormwater management basin below the site (though not immediately below). As ollow- yp: Engineering requests plan include reduced scale (1" =200') inset showing location of regional SWM basin relative to site to help eliminate confusion for those less familiar with SWM network in this development area. i. County SDP or WPO file # where regional SWM basin is approved. Please ref. county SWM Facility ID 0192.01 or 0060.01, which appear to be the only likely options in GIS inventory of SWM facilities below the site. (Apart from these, an unnamed tributary to Moore's Creek flows north, beneath interstate (I-64) without, apparently, encountering another SWM detention facility. (Rev. 1) Withdrawn. See SDP2005-00069 for prior (approved) plan reference to `stormwater detention pond designed and approved with the Mill Creek Industrial Park.' Engineering Review Comments Page 5 of 7 ii. County GIS lists the following SWM facility information (0192.01, UU60.01): (Rev. 1) NA -Review error. Images deleted. iii. Provide copy of legal instrument whereby Peabody School has right to release site runoff to Foxcroft detention basin (provide deed bk-pg. ref.), to Mill Creek P U D HOA retention basin, or any other stormwater management facility relied upon. (Rev. 1) Withdrawn. Site currently discharges to regional detention pond under approved WPO201300033, and will continue to discharge to this facility. No additional legal instrument is required. iv. Provide as -built design information and routings for the dry detention basin /retention basin (wet), if relied upon, to show compliance with 9VAC25-870-66. (Rev. 1) Withdrawn /NA since project subject to Part IIC. v. If the Foxcroft /Mill Creek facilities are eligible for use by Peabody School, 9VAC25- 870-66 applies, a SWM Facility /BMP Maintenance Agreement listing Peabody School, and bk.-pg. ref. to Deed of Dedication for either Foxcroft or Mill Creek basin are required. (Rev. 1) NA -Review error. Engineering Review Comments Page 6 of 7 vi. Show Foxcroft dry detention basin or Mill Creek wet retention basin on plans with bk.-pg. reference to deed of dedication of easement for whichever facility may be relied upon. (Rev. 1) Not addressed. Please see item e. follow-up, above. vii. WPO201900018 SWM Narrative: (Rev. 1) Image deleted; not needed. viii. WPO201300033 SWM Narrative: (Rev. 1) Image deleted; not needed. WPO201300033 SWM design may already credit removal of existing classroom building, but values presented as well as SWM narrative, leave uncertainty. If credit was taken for removal of the existing classroom (loss of impervious area) with WPO201300033, then WP0201900018 cannot take this credit. Please revise and clarify impervious values that appear on sheet 1 and 6. Compare with WPO201300033 (sheets 1, 5, SWM Narrative). Ensure values bridge to WPO201300033, accurately, that values reported on sheet 1 and 6 are consistent. If credit for removal of the existing classroom building was not taken with WPO201300033, provide table description of buildings with areas (name buildings/list sq.ft.), proposed and existing, that match WPO201300033 sheet 1 values. Revised WPO201900018 review will consider: (Rev. 1) Addressed. Ref. Sheet 1 Existing and Proposed Impervious Area tables. WPO201300033, sheet 1 (values): (Rev. 1) Image deleted; not needed. WPO201900018 sheet 1: (Rev. 1) Image deleted; not needed. WPO201300033, sheet 5: (Rev. 1) Image deleted; not needed. WPO201900018, sheet 6: (Rev. 1) Image deleted; not needed. 10. New: Third and fifth paragraphs of SWM Narrative, sheet 5, reference attached stormwater management calculations. Calculations packet was not included with submittal, unless overlooked. Please submit print copy or .PDF. Additional review comments possible. 11. New: Revise sheet 1 table notation to read: `Total increase of impervious area: 0.09 Acres or 4,388 SF.' 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 for reasons listed, below. The erosion control plan content requirements can be found in County Code section 17-402. 12. Sheet 5: Include paved wash rack detail. (Rev. 1) Addressed. 13. Sheet 7: Include VESCH SAF detail. (Rev. 1) Addressed. Sheet 8: 14. Provide trapping measure for sediment -laden or otherwise contaminated storm runoff from paved construction entrance, concrete wash -out, dumpster, porta John, etc. (Rev. 1) Addressed. 15. Show concrete wash -out. (Rev. 1) Addressed. 16. Ensure waste management vehicles can access dumpster, once construction fencing is set up. (Rev. 1) Not addressed. 17. New: Restore Utility, Grading and Drainage Plan to VSMP /WPO plan set. Details at 1" =20' scale are more readable, and not all labels repeat on sheet 5. WPO plans should include grading and drainage plans. 18. New: Relocate proposed rubber -lined concrete wash -out area text which obscures existing curbed entrance. The VSMP permit application and all plans may be resubmitted for approval when all comments have been addressed. For re -submittal, please provide 2 copies of the 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. Engineering Review Comments Page 7 of 7 Process After approval, VESCP plan 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 may 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.

Applicant 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 disturbed, 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 grading permit will be issued by the County so that work may begin. County forms can be found on the county website forms center under engineering; http://www.albemarle.ora/deptforms.asl2?department=cdengmTo Ifyou have questions /concerns, please contact me at janderson2C&albemarle.org, or at 434.296-5832-x3069.
