Erosion and Sediment Control Plan (ESCP) Engineering Review Comments Page 3 of 4 Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. This plan is disapproved for single minor reason listed, below. The erosion control plan content requirements can be found in County Code section 17-402. 1. C3.4: Provide proposed ditch x-section for ditch along E edge of new parking. 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. 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 are 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. Effective April 1, 2023, the Northern Long -Eared Bat (NLEB) is protected as a designated endangered species under the Endangered Species Act. Coordination with U.S. Fish & Wildlife Service (USFWS) may be required for any tree -cutting activity, April 1 thru November 14, for trees >3-inch diameter, at breast height. Use this link to notify USFWS of project activity. Project relies on 0.11 lbs. phosphorus nutrient credit from WPO201800013 (Birdwood Golf Course) and on - site bioretention basin (2.54 lb/yr TP load reduction); bioretention basin requires SWM facility easement. No additional nutrient purchase is required or anticipated. 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 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 Applications: hqs: //www. albemarle. org/govemment/community-developmeaVapplly-for/engineering-applications Thank you.
