Main St. Suite M, Charlottesville, VA 22902 f iustin(a)shimp-enizineering com] Owner or rep.: HTC Hotel LLC, 8901 Brook Road, Glen Allen, VA 23060 Plan received date: 7 May 2018 Date of comments: 20 June 2018 Reviewer: John Anderson WP0201800031 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 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 ESCP, (3) a SWMP, and (4) any TMDL measures necessary.

Sec. 1, Reizistration Statement —Revise to read South Fork Rivanna River; sign /date. 2. Sec. 4 /5 (ESC /SWM Plans) — Update these sections with revised plan sheets. 3. Sec. 9, Signed Certification — sign /date. * Recommend Shimp Engineering contact reviewer to schedule day /time to update SWPPP at COB; SWPPPP may be left for pickup at CDD front desk. SWM Plan 1. Revise Title to read: VSMP Plan for Hollymead Town Center Hotel (eliminate word Site). 2. Stormwater Management: Relocate note that appears after Stage 4 sequence of construction to just after Project Description. Revise note to reflect percent impervious proposed with HTC Hotel, which appears to approach 100% of GIS -mapped TMP #32-41D5 (image below). If BLA has adjusted acreage of TMP #32- 41D5, provide recorded copy of plat. Adjust acreage to reflect increased parcel size, as GIS real estate records correspond with plan information that area of parcel TMP #32-41 D5 is 1.97 Ac. 3. SWM Plan booklet a. Update Open Space Exhibit, as required, to match recorded parcel acreage and boundaries —see also comment C_2., below. It is essential that % impervious with this project not place adjacent parcel/s (TMP #32-41D6, for example) at a future development impervious area ceiling deficit. b. Open Space Exhibit appears to show off-site areas as turf /open space which may be included in calculation of project overall site impervious area. Exclude all areas beyond project LOD. Revise % impervious calculation and update booklet, VRMM .xls, and plan sheets, as necessary. 4. Engineering Review Comments Page 2 of 3 c. Confirm property boundaries as shown are accurate, consistent with recorded plats, established boundaries, and county real estate records. Provide evidence that boundaries are accurate. d. Transfer .PDF image of 5/4/18 Shimp Engineering booklet cover letter to plan sheet; this information informs SWM plan review. Y A /Ap P/ I Provide SWM design for portion of proposed impervious area that exceeds water quality /quantity capacity of future Regional Stormwater Pond, if needed, as required per 9VAC25-870-65 (Part IIB /water quality); 9VAC25-870-66 (quantity). B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. See A., above. Update Sec. 6 Exhibit, as needed. C. 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 minor reason outlined in single comment, below. The erosion control plan content requirements can be found in County Code section 17-402. 1. C-2 2. C-3 3. C-4 a. ESC Note 11: revise last sentence to read: `Any sediment buildup shall be removed.' b. General Note 10: Revise since Owner must obtain bonds, not the Contractor. c. Sequence of Construction: Relocate Stage 2 items 4 and 5, to Stage 3, prior to item 2. a. North boundary parcel TMP #32-41D5: does not match GIS real estate records; furnish recorded deed with plat that establish north boundary of parcel matching boundary shown on plans. a. VESCH Std. & Spec. 3.09, Diversion Dike i. "The channel behind the dike shall have a positive grade to a stabilized outlet." Provide positive grade by shifting south end of dike west, more interior to the site. Dike shown includes slight uphill portion, and appears zero grade over a distance of 200'. Revise design such that sediment -laden runoff from site interior reaches the sediment trap. ii. Provide SF behind relocated portion of DD. iii. Where DD parallel with road exceeds 2%, provide stabilization in accordance with VESCH Std. & Spec. 3.17 (ref. VESCH p. III -54). CCS: List CRS in ESC legend. Engineering Review Comments Page 3 of 3 Process Immediately upon plan review approval, contact County Management Analyst to discuss nutrient credit purchase requirements prior to purchase of nutrient credits. Ana Kilmer will provide critical guidance prior to purchase. (A. Kilmer —tel. 434.296-5832 —x3246; akilmer@albemarle.org ) VSMP plan approval requires recorded permanent drainage easement between new or proposed on-site BMP (UG detention, for example) and existing (future) Regional Stormwater Pond. VSMP Plan approval also requires Applicant provide circuit court copy of recorded SWM Facility Maintenance Agreement. If an existing SWM Facility Maintenance Agreement for the future Regional Stormwater Pond includes current owner/developer of parcel TMP #32-41D5, provide copy of legal instrument ("Agreement'') which establishes shared or pro -rated SWM facility maintenance responsibilities of the owner of TMP #32-41 D5. 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 (see above). 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 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 joint VSMP and 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; Ifyou have any questions or concerns, please contact me either by email (janderson2(&albemar1e.org) or by phone at 434.296-5832 ext. 3069.
