This project is approved. See the process for the bonding procedure below. 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 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.

This project is denied. The rationale is given in the 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. 1) Include the registration statement in the SWPP booklet. For future submissions, please use the Albemarle County SWPP template. It can be found in the following link: http: // www.albemarle.org /dgtforms.asp ?department= cdengnoo B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17 -404. 1) Include an 11 "x 17" Pollution Prevention Plan map showing concrete washout, porta johns, fueling stations, and trash containers. This will be marked up by the contractor as construction of site progresses. 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) The title on the plans should state "VSMP" Engineering Review Comments Page 2 of 3 2) The LOD area noted on sheet C -20 is 4.6 acres. Please provide a note on the title sheet to clarify that this area is covered under an existing general permit and state the registration number. 3) I compared sheet C -19 of Stonefield Block G to the approved sheet 29 of Stonefield Block F and G. There are stormsewer pipes on Block G that appear to be existing, but do not match what was proposed on the previous block F &G plans. The demo sheet clarifies some revisions to the pipe layout. Please clarify other pipes so it is clear what is already installed, what are revisions to the previous approved plan under Stonefield Block F & G, and what are new proposed pipes under this plan. Also, include new profiles for stormsewers if they changed from the previously approved WPO plans. 4) On sheet C -14, under Stormwater Narrative, a note refers to WPO2010 -23. However, another plan was approved under WPO2013 -69, where the North SWM Facility layout and vortechs stormfilter were revised. WPO2013 -69 should be noted in the narrative as well. Also, it should be noted in this proposal that the vortechs location has been shifted slightly to a new location. Provide revisions to the stormsewer pipes and the vortechs profiles since it has changed from the previously approved plans. 5) Label existing str 160.1 on sheet C -11. 6) On sheet C -10, many exisiting structures' inverts in/out and top elevations do not appear to match what was approved in the previous WPO2013 -69. It is labeled as existing on this plan, but it is unclear if these are as -built info or just revisions to the previous plan. Please clarify on the plan. 7) For str 178 (existing) match top elevation on sheet C -10 with sheet C -12. 8) Is the pipe between existing STR 160 -160.1 being proposed or is it already built? It is shown as a thicker lineweight, but it is not shown in the profiles. Please clarify. 9) For the north swm facility please update the tables labeled Albemarle Place Pre /Post Development Runoff Analysis, Albemarle Place BMP Computations Summary and Albemarle Place SWM Facilities Storage Volume. Please include with the proposed plans. This can be obtained from sheet C -25 WPO2010 -23. Update calculations pertaining to the north SWM facilities. 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) On sheet C -20 under sequence of construction, note no 2 refers to WPO- 200900074. This should be coordinated with the approved WPO2013 -69. Please state in note no 2. The VSMP permit application and all plans may be resubmitted for approval when all comments have been satisfactorily addressed. For re- submittals please provide 4 copies of the complete permit package with a completed application form. All revisions to calculations shall be resubmitted, signed, sealed and dated. Engineering plan review staff are available from 2 -4 PM on Thursdays, should you require a meeting to Engineering Review Comments Page 3 of 3 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 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.
