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). d. 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 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. VAR10C512 was terminated, July 2018. This is a new application subject to Part 1113 technical criteria. (Rev. 1) Withdrawn /NA since project subject to Part IIC. WP0201300033, sheet 5 /bioretention basin design (Image removed with Rev. 3): e.

Provide supportive information on the `regional basin,' including (but not limited to): (Rev. 1) Wit 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. (Rev. 2) Comment persists. Also, see email sent 6/5/2019 7:41 AM. (Rev. 3) Addressed. See plan sheet 5A and Reference Dwg. 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 (Rev. 1) Withdrawn.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.' (Rev. 1 image removed with Rev. 3) ii. County GIS lists the following SWM facility information (0192.01, 0060.01): (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 WP0201300033, 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. 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. (Rev. 3) Addressed. vii. WP0201900018 SWM Narrative: (Rev. 1) Image deleted; not needed. Engineering Review Comments Page 4of5 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 WP0201300033, 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.

WPO plans should include grading and drainage plans. (Rev. 2) Addressed. (Reminder: Engineering to check final print submittal). 19. New: Relocate proposed rubber -lined concrete wash -out area text which obscures existing curbed entrance. (Rev. 2) Addressed. All comments have been addressed. Please see Review Comment Sec. A: Provide signed Registration Statement as soon as possible. Engineering Review Comments Page 5 of 5 Process After approval, VSMP plan will need to be bonded (Rev. 3: in process, 6/6/19). 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 ..,:'� has prepared 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 nee *� be comp't and recorded. (Rev. 2) See Ex. SWM Facility Maintenance Agreement at bk.-pg. 4399-529. 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. An easement plat associated with this VSMP plan is under review (SUB201900081) and must be recorded prior to Engineering recommendation to approve Peabody School Minor Site Plan Amendment —see Attached email. After bonding is complete and required easemet#s are er-de (Forest /(lpe Spaoe for example), the County can hold a pre -construction conference. Applicant will need to complete the request for apre-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 maybegin.
