High St. Charlottesville, VA 22902 Justin M. Shimp; justin(&shimp-en ing eerin,g corn Owner or rep.: Horseshoe CV LLC, P.O. Box 69, Richmond, VA 23218 fiorlandi(a4riverg com ] Plan received date: 2 Jan 2020 Date of comments: 30 Jan 2020 Reviewer: John Anderson 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 for reasons listed below. The VSMP application content requirements can be found in County Code section 17-401. A. Stormwater Pollution Prevention Plan (SWPPP) — Required, although a Linear Project. Please submit using county template. 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. This SWPPP is disapproved, and the reasons are provided in the comments below. 1. No SWPPP; please submit using county template. 2. Please ref. Horseshoe Farm VSMP /WP02020-00002 on SWPPP cover. B. Stormwater Management Plan (SWMP) VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This plan is disapproved for reasons listed, below. The stormwater management plan content requirements can be found in County Code section 17-403. 1. Project proposes a network of mountain bike trails through woods. This several mile network of trails iE eligible to be reviewed as a linear project under DEQ Guidance Memo No. 15-2003, Apr 23, 2015 /link: https://www.deq.vir ig'nia.gov/Portals/0/DEQ/Water/Guidance/152003.pdf. Under this DEQ policy guidance, SWM quality /quantity requirements are presumed to be met, provided specific conditions are met. Please include the following, verbatim, on title sheet. 5IDRMWATER MANAGEMENT COMSIDERATIONS -THE PROJECT DOES NOT SIGNIFICANTLY ALTER THE PREDEVELOPMENT RUNOFF CHARACTERISTICS OF THE LAND SURFACE AFTER THE COMPLETION OF CONSTRUCTION AND FINAL STABILIZATION; -THE PROJECT IS MANAGED SO THAT LESS THAN ONE (1) ACRE OF LAND DISTURBANCE OCCURS ON A DAILY BASIS; -THE DISTURBED LAND WHERE WORK HAS BEEN COMPLETED IS ADEQUATELY STABILIZED ON A DAILY BASIS; -THE ENVIRONMENT IS PROTECTED FROM EROSION AND SEDIMENTATION DAMAGE ASSOCIATED WITH THE LAND -DISTURBING ACTIVITY; -THE OWNER AND/OR CONSTRUCTION ACTIVITY OPERATOR DESIGNS, INSTALLS, IMPLEMENTS, AND MAINTAINS POLLUTION PREVENTION MEASURES TO: -MINIMIZE THE DISCHARGE OF POLLUTANTS FROM EQUIPMENT AND VEHICLE WASHING, WHEEL WASH WATER, AND OTHER WASH WATERS; -MINIMIZE THE EXPOSURE OF BUILDING MATERIALS, BUILDING PRODUCTS, CONSTRUCTION WASTES, TRASH, LANDSCAPE MATERIALS, FERTILIZERS, PESTICIDES, HERBICIDES, DETERGENTS, SANITARY WASTE, AND OTHER MATERIALS PRESENT ON -SITE TO PRECIPITATION AND TO STORMWATER; -MINIMIZE THE DISCHARGE OF POLLUTANTS FROM SPILLS AND LEAKS AND IMPLEMENT CHEMICAL SPILL AND LEAK PREVENTION AND R ESPONSE PROCEDURES; -PROHIBIT THE DISCHARGE OF WASTEWATER FROM THE WASHOUT OF CONCRETE; -PROHIBIT THE DISCHARGE OF WASTEWATER FROM THE WASHOUT AND CLEANOUT OF STUCCO, PAINT, FORM RELEASE OILS, CURING COMPOUNDS, AND OTHER CONSTRUCTION MATERIALS; AND -PROHIBIT THE DISCHARGE OF FUELS, OILS, OR OTHER POLLUTANTS USED IN VEHICLE AND EQUIPMENT OPERATION AND MAINTENANCE. Engineering Review Comments Page 2 of 4 2. Proposed bike network is extensive. Show potential points of equipment entry into wooded untraveled and undisturbed areas. Provide paved construction entrance at each entry point from a paved surface (inspector may require a stone construction entrance, but plan must preserve paved construction entrance option). 3. Submit Floodplain Development Permit Application (FDP) for proposed activity within limits of mapped (FEMA) floodplain. Ref. 18-30.3.12. Link to FDP application: hqp://www.albemarle.orgLupload/images/forms center/departments/Community Development/forms/Engineering_and _WPO Forms/Floodplain_ Development_Pennit.pdf 4. County plan approval does not affect or supersede requirement to coordinate this project with an array of state /federal agencies; for example: DEQ, VMRC, VDHR (heritage sites), DCR (heritage resources — insects /plants), VDGIF /USFWS (species), or USACE (Waters of the U.S. /wetlands). Please coordinate potential project impacts and additional permit requirements with relevant review agencies. 5. C4: For the moment, proposed bridge crossing of S. Fork Rivanna River cannot be approved. For approval, coordinate Zoning and Floodplain Administrator approval, demonstrating that crossing is acceptable to Zoning, and that design of proposed crossing meets standards listed at 18-30.3.13 through 30.3.15. 6. If stream crossing of S. Fork Rivanna River persists as a design feature, provide additional plan /profile detail required to evaluate FDP Application. `No Rise' in base flood elevation is a primary review consideration. 7. While 17-603.C. lists bicycle paths as a type of structure, improvement, or activity authorized in a stream buffer, stream buffer impacts must be offset 2:1. To the extent proposed trail impacts stream buffer, propose Mitigation Plan (sheet) that outlines efforts to minimize stream buffer impacts, and proposes offset mitigation. Please ref. Table B, p. 95 of document titled Riparian Buffers Modification and Mitigation Manual, listed at: hqs://www.deq.virginia.gov/Portals/0/DEO/Water/Publications/Ril2arianBufferManual.pdf 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 reasons listed, below. The erosion control plan content requirements can be found in County Code section 17-402. C2 1. Provide a text note that defines by location and description points of equipment access required to construct the trail network, whether from a public right-of-way, via Ex. access road only (internal to parcel), or via a combination of the two. 2. Describe Ex. access road (dirt, stone, fire road, etc.) 3. If trees are to be removed from parcel interior (this is not a logging operation, per se), describe effect /minimize impact of tree removal on natural resources, especially aquatic /riverine /wetland resources. C3 4. Revise S. Fork Rivanna River label (sheet, lower -left) to read Mechums River (ref. GIS). 5. Label Moormans River. 6. Label Horseshoe Bend Road. 7. Label Free Union Road, Rt. 601. C3-C8 8. Clearly label all points of access, whether from paved public roads, private streets, or Ex. access road; that is, point/s at which track equipment enters wooded terrain. Provide adequate construction entrances at a reasonable number of points to undertake this work. Entrances not shown are not approved with this plan. 9. Show and label critical slopes. 10 r �E) Engineering Review Comments Page 3 of 4 Coordinate with Albemarle County, CDD/ Zoning -Planning, regarding potential intensification of use in a rural area (bike trail may qualify as accessory use to residential use). Please coordinate. Point of contact: Scott Clark /Planning Division ( sclarkgalbemarle.org ). C4-C8 11. On each sheet, provide an identical typical 1" = 10' scale drawing that clarifies that LOD is a narrow strip < 20' or similar width required to construct the trail. LOD is somewhat ambiguous since shown as a double dashed line. Albemarle hopes to avoid any confusion or mistaken view that LOD measures hundreds of feet wide, which may happen if LOD is viewed as a single -dash line. A typical inset detail (1" = 10') should help clarify. Please include a Note that detail is a Upical detail, that width may vary (Note: Engineering maintains it is important that plan clearly indicates trails qualify for review as a linear project.) 12. Provide match lines. 13. C6, C8, C9: Note reading: `Install silt fence parallel to trail when trail is within 100 feet of waterway, or as directed by the County Erosion and Sediment Control Inspector,' appears reasonable, given additional limits on land disturbance that apply to linear projects (item 1., SWMP, above). As consequence, Albemarle requests estimate of quantity of silt fence reasonably anticipated to be required, and whether one hundred (100) wattles seems a reasonable estimate needed to complete construction (wattle installed unit price =?). These quantities will help support VSMP /ESC Plan bond. ESC Plan bond is required. C10 14. Provide a typical section (similar to typical section for a bike or multi -use path) that shows proposed mountain bike trail width and 3'-5' (vertical?) bench cut described at Note 2, sheet C1, required to establish the mountain bike trail network. 15. Provide view or image of straw wattle that includes recommended installation steps to guide construction inspection. Caption this view "x 45 (Typ.)" (or whatever final swale crossing count is). If two wattles are proposed at each swale, please clarify. Should additional swales require straw wattles, VSMP plan revision is not required but coordination with ESC inspector is an expectation, necessity, and minimum requirement. 16. Provide ACDSM paved construction entrance detail (ACDSM, p. 8). 17. Provide VESCH, 3' Edit., 1992, Std. & Spec. 3.02, Temporary Stone Construction Entrance detail. Engineering Review Comments Page 4 of 4 D. Pollution Prevention Plan (PPP) — Ref. SWPPP, Sec. A The PPP content requirements can be found in County Code section 17-404. This plan is disapproved 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. After bonding is and ag feements 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 (SWPPP Registration Statement). 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, the County can hold a pre -construction conference. Applicants will need to complete the request using 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 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; hLtp://www.albemarle.org/deptforms.asp?department--cdengmTo Ifyou have questions /concerns, please contact me atjanderson2(&albemarle.org or at 434.296-5832-x3069.
