Stormwater Management Plan (SWMP) VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This plan is approved. 1. A SWM Facility Easement Plat is required for this project. (Rev. 1) Withdrawn. Initial comment is revised to require Stormwater management maintenance agreement, Sec. 17-415, which ensures county access for periodic inspection/maintenance, and stipulates owner obligation to maintain SWM facilities. Platted easement is not, however, required. Platted easement with deed is required for: subdivision developments [ 14-428], site plan developments [ 18-32.7.4.2], and if a forest -open space (FOS) area /acreage value is entered as post -developed land cover in VRRM.xls [DEQ Guidance Memo No. 16-2001, May 2, 2016]. Chapter 17 alone does not stipulate easement requirements for SWM facilities. Ch. 14 and 18, however, do. This site does not require a site plan and does not propose subdivision or FOS Easement, therefore, platted easement and SWM facility deed are not required. A SWM Facility Maintenance Agreement and surety /bond for SWM facilities are required. T-1$ CO.0 2. Revise title to include VSMP /WP02020-00007. (Rev. 1) Addressed. 3. Revise Note 2.

Ensure energy balance equation indicates compliance. (Rev. 1) Persists. Also, item 50., below. (Rev. 2) Partially addressed. Applicant: `Stormwater design has been revised to comply with Energy Balance for the disturbed areas that will be concentrated in the post condition'. As follow-up: Please see email sent 3/8/2021 9:00 AM, which includes: `To be consistent with what we've required on other projects, the engineer should show the flowrate and orifice size required to meet the energy balance in addition to the flowrate resulting from the 3" orifice. They need to also request an Exception from the regulations to discharge more than what the energy balance allows. The request should be a letter with a fee ($240) and the letter should compare the rates and provide justification for using a 3-inch discharge.' If unable to meet the energy balance requirement with a 3-inch orifice, please request an exception requesting to construct underground detention shown on C6.0 with a 3-inch orifice, rather than 2.5".

C-1.3 and C-1.9 provide a partial, somewhat confusing analysis of drainage and SWM compliance data. (Rev. 1) NA — Design revised. 23. Revise using I.F. = 0.8. Engineering check, energy balance: Qpost = (0.8)(14.50)(0.20)/0.53 — Qpon &e i.. d. (Rev. 1) Persists —Although design revised, this comment is relevant. Water quantity compliance requires energy balance since proposed discharge is to a natural conveyance (ref review item 50., below). Note: Simply altering location of outfall does not address comment. Given slopes across site, ELS is a non -viable stand-alone concentrated -to -sheet flow transition device. Runoff must be detained (reduced) on this site.

Increased volumes of sheet flow resulting from pervious or disconnected impervious areas, or from physical spreading of concentrated flow through level spreaders, must be identified and evaluated for potential impacts on down -gradient properties or resources. Increased volumes of sheet flow that will cause or contribute to erosion, sedimentation, or flooding of down gradient properties or resources shall be diverted to a stormwater management facility or a stormwater conveyance system that conveys the runoff without causing down - gradient erosion, sedimentation, or flooding. If all runoff from the site is sheet flow and the conditions of this subsection are met, no further water quantity controls are required. a. Initial design included detention, a SWM facility that would limit runoff without causing down - gradient erosion, sedimentation, or flooding. b. Please revisit /restore stormwater management facility design to this VSMP. c. Revise /delete reference in plan narrative, or calculation report that water quantity is met by sheet flow, without detention, with an ELS.

Ensure diversions and all ESC can be maintained, as proposed, throughout construction. . (Rev. 1) Persists. (Rev. 2) Addressed. Applicant: `Notes have been added to Erosion and Sediment Control Phase 2 to better convey to the contractor and planner the construction sequence that shall occur in order to maintain acceptable Erosion and Sediment Control measures until site stabilization is completed.' 2. Label OPI, OP2. (Rev. 1) NA — Design revised. 3. Recommend initial location for staging and parking, solid waste dumpster, port-a-john, and concrete washout that does not require relocation for installation of detention system, or culvert 5.

Provide design details for level spreader (ELS) at outfall of culvert 3. Ref. VA DEQ Stormwater Design Specification No. 2, Table 2.2 for ELS design criteria (13 lin.ft. per each 1 cfs of inflow). (Rev. 1) May persist. An ELS may transition concentrated release from a detention system /SWMfacility to sheet flow. Provide design details for any ELS that persists as a design feature. (Rev. 2) Addressed. Applicant: `The design has been updated to include detention for the concentrated runoff from the proposed impervious areas in the post condition. Energy balance is being met for the concentrated stonnwater outfall and the ELS has been removed.' 6. Include ELS, culvert 3, in SWM narrative. (Rev. 1) NA — Design revised. 7. Label all culverts on this plan sheet. (Rev. 1) Addressed, 8. Revise CE symbol at site entrance to PCE (paved entrance). (Rev. 1) Not addressed. (Rev. 2) Addressed. 9.

Provide ESC phase interim to phase 1 (C3.2) and 2 (0.3) that shows phase 2 final site grading with phase 1 sediment traps: (Rev. 2) Items a: k., addressed, via labels, ESC sequence notes, measures, and linework. a. Phase 1 sediment traps (STI, ST2) control runoff from 3.82 Ac. b. Phase 1 indicates trap placement, diversions, but apart from ST grading, no grading, whatsoever. c. Phase 2 indicates final, built condition, but no sediment traps. d. The interim phase, where all site work/grading and building construction occur while STs receive diverted runoff during constructive phase, are not shown. e. No ESC information is provided for the entirety of site grading /building construction. f Phase 2 presents sparse perimeter controls unequal to challenge of controlling runoff from 3.82 Ac. DA, once diverted to sediment traps, now released to newly -graded fill slopes. g. Final grading proposes uniform contours that in theory support sheet runoff, once stabilized. h. Stabilization may not occur for weeks, or months. Until site is stabilized, sediment traps must operate with relocated diversions routing runoff from graded slopes to same /similar traps, with Engineering Review Comments Page 7 of 8 diversions designed to convey runoff to the traps. Also, please consider temporary slope drain/s. i. In ESC phase 2, no ESC or channel design is provided for concentrated runoff at intersection of existing grade and proposed grade at NW side of site. The total vertical fall on the NW side of the site is 40' (658' — 618'). Design permanent storm conveyance channel (may be grass -lined if velocity non -erosive /provide EC-2, EC-3 matting, as needed) where runoff concentrates. Evaluate channel velocity, and armoring (EC-2, EC-3), as needed (blU0 aFFOIN b010 ). [Image removed with Rev. 2 comments.] j. Please consider permanent surface water diversion to collect /divert runoff from edge of parking lot to base of slope, rather than across slope face. Design assumes slope stability, even if parking lot runoff releases across 15'-20' H fill slope. Sheet runoff from impervious areas across newly constructed fill slopes of this height will likely cause rill erosion, which may worsen, or prove difficult or expensive to fix, once rills established. This is a recommendation. Also, see 18- 4.3.3.C.4. k. C3.3: Perimeter controls for expanse of 15-20' high fill slopes are inadequate, or simply not provided. Provide adequate phase 2 perimeter controls, see image, belo : [Image removed with Rev. 2 comments.] 15. C3.2 a. Label ST floor dimensions in plan view (L x W). (Rev. 2) Addressed. b. Label ST stone weir dimensions, plan view (L x W). (Rev. 2) Withdrawn, 16. New: Recommendation unrelated to WPO (Note, An SDP Application is not required, agricultural use): Since project does not require a site or road plan, VDOT will not see information shown on C5.1, Sight Distance Profile. Recommend coordinate entrance design at Markwood Road with VDOT since sight distance (left) profile indicates SDL is within 3" of existing grade at SDL station 350'. VDOT may offer recommendation; in any event, post -construction adjustment would only require slight additional cut beyond public RW, on development property, to ensure unobstructed SDL, left (so, not a critical issue). (Rev. 3) Addressed. Applicant response: `Acknowledged. VDOT has reviewed and notes sight distance will be field verified after grading is completed.' 17. New: Recommend revise C6.0 SR 664 — Markwood Road label to read `prescriptive'. Typo, not critical. (Rev. 3) Addressed. The VSMP permit application and plans may be resubmitted for approval when comments have been satisfactorily addressed. Once plans are revised, Engineering encourages digital submittal. Process: After approval, plans will have to be bonded. The bonding process is begun by submitting a bond estimate request form and fee to the Department of Community Development (Note: received Aug-6, 2021). 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 have to be completed by the owner and submitted along with cash, certificates or sureties for the amounts specified. The agreements will have 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 have 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 have to be submitted along with court recording fees. After bonding and agreements are complete, county staff will 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 have 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 must complete the request for a pre -construction conference form, and pay the remainder of the Engineering Review Comments Page 8 of 8 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.
