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 Engineering Review Comments Page 4 of 4 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.

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. 1. Provide an updated, signed registration statement for Old Trail that includes the disturbance from this proposed development. 2. Ensure the latest, approved sheets get inserted into the master SWPPP for Old Trail. B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. Ensure the latest, approved sheets get inserted into the master PPP for Old Trail. 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. [cover sheet] List title of plan/exhibit and date of approval for critical slopes analysis/determination. (8-30-18, Critical Slope Exhibit Old Trail Village Block 32) 2. [cover sheet] List title of and date of approval of floodplain development permit. (11-6-18, FDP201800018) 3. [cover sheet] Update the plan number to be WP0201800077. 4. Sheets 5 & 6 should provide a narrative stating the difference between the master plan and this proposed/actual plan. Differing drainage areas were shown, however, must show overall compliance with the master plan such as allowable flows and removal rates, etc. Approved plan Engineering Review Comments Page 2 of 3 information was provided, however actual, proposed information showing compliance is not clear. 5. Provide routings for stormwater facilities. (not on the plans, separate calculation booklet is fine). 6. What are the proposed WSE's of the S-1 facility? 7. Location of the existing emergency spillway for the extended detention is unclear. Please clearly show the location and dimensions. 8. For the extended detention, Per 3.07-24 of the VA SWM HB, show the proposed buffer zone. 9. For the bioretention, show surface area sizing Per Table 3.11-4 of VA SWM HB. 10. Provide pipe calculations and DA for all pipes associated with SWM (outfall, etc). Other pipes will be shown in the site plan or road plan, correct? 11. Provide planting/landscape plan for proposed extended detention/biofilter area. 12. Ensure the proposed disturbance to the stream buffer complies with the areas approved in the ZMA. Table 9 of the master plan, Conceptual Buffer Encroachment, does not show any for S-1 or 5-13. Sheet 3 of the ZMA, SWM and stream conservation plan, does not appear to show any disturbance either. However, section 4.2.2.9 does discuss buffer encroachment in the 5-13 discussion. 13. Provide the construction record drawing requirements on the plan. http://www.albemarle.org/upload/images/forms_center/departments/Community Development/for ms/En ing eering and _WPO_Forms/WPO_VSMP_Construction _ Record_ Drawings Policy 23Ma 2�pdf 14. It was hard to read the text, but on Sheet 09, was 90% efficiency used for bioretention? Table 5-14 in the VA SWM HB does not show a 90% option. Please clarify. D. 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, 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. Clarify the legend. There are two different floodplain hatches with the same label (floodplain AE). 2. Provide outlet protection for all pipes (into biofilter, extended detention and S-1 basin). Show outlet protection sizing calculation. 3. [Sheet 7] Sequence of construction should be more site specific. Should reference the difference between phases and conversion of controls from existing conditions (Phase 1) to Phase 2 as well as conversion to stormwater facilities. 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 Engineering Review Comments Page 3 of 3 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. County forms can be found on the county website forms center under engineering; htip://www.albemarle.org/deptforms.asp?department--cdengwpo
