Main St., Suite M Charlottesville, VA 22902 fiustin(a,shimp-engineering.com ] Owner or rep.: Rio Vista LLC, PO Box 5787, Charlottesville, VA 22905 Plan received date: 22 May 2018 (Rev. 1) 20 Sep 2018 Date of comments: 3 July 2018 (Rev. per SRC) 10 July 2018 (Rev. 1) 21 Sep 2018 Reviewer: John Anderson Project Coordinator: Christopher Perez SUB2018-00097 1. An approved WPONSMP Plan is required prior to final plat approval. Consider stormwater quality and quantity (engineering design) alternatives at level of detail required to show conceptual locations of required drainage, and SWM treatment or detention required for an approved VSMP Plan; provide conceptual locations with preliminary plat (14-302.A.13). 2. Delete C1 Subdivision Note 6, which appears to assume a pre -determined VSMP/WPO review outcome. For example, in plan review meeting with Applicant, need for curb and gutter for eventual conceptual design (essentially, two driveway entrances off Rio Road instead of a private street or public road) was discussed. Streets in an urban areas require an urban section, which requires curb and gutter. Applicant, in letter request for exception (Section 14-404(A)), dated 8/24/18, states that `Compliance with subsection G [ 14-410(G)] is anticipated with the review of a final plat application,' which means the Applicant rightly anticipates drainage elements are required. 14-410(G): G. Drainage. Adequate drainage control shall be provided for streets by installing culverts under streets; side, lead, or outlet ditches; catch basins; curb inlets; or any other devices, including piping, ned as determito be necessary by the county engineer. All of these improvements shall meet the standards of the county or, in the event no county standards exist, Virginia Department of Transportation standards. Once system elements, including piping, concentrate runoff from proposed impervious area, Chapter 17 stormwater quantity requirements listed at 9VAC25-870-66 require both channel and flood protection requirements that conflict with apparent proposal to discharge concentrated runoff directly into the floodplain (or floodway) without attenuating stormwater peak discharge or velocity. In any event, plan review will consider stormwater-related design issues, once a VSMP/WPO plan is submitted. 3. Related to 2., show conceptual location/s of SWM pipes that avoid preserved steep slopes. 4. Related, propose location/s for SWM facilities that may be required that avoid streamward 50' of buffers. 5. Related, if a SWM facility is proposed to lie within the 100 -year floodplain, design may not include fill, or decrease the cross-sectional area of the floodplain or floodway of Meadow Creek, at any point. 6. A new sanitary sewer is proposed within the 100 -year floodplain. Submit a Floodplain Development Permit Application to show (that): a. Construction of the proposed sanitary sewer line does not decrease the cross-sectional area of the floodplain at any point; does not increase the base flow elevation of the floodplain at any point. Engineering Review Comments Page 2 of 3 b. Development activity will not increase the base flow elevation (BFE) or extent of the floodplain at any point (no increase in horizontal dimensions of floodplain). c. Applicant is directed to Code 18-30.3, Flood Hazard Overlay District, especially 30.3.11 - 30.3.15 (Note: 30.3.15.A.6 is of particular relevance; table at 30.3.11 provides by right water -related and public utility use within a FEMA FIM Map Zone AE regulatory floodway). d. Regulatory floodway. Ref. on-line VFRIS (image below). e. Regulatory floodway on preliminary plat, sheets C2 and C5 (14-302.B.9). f. Also, with the FDP Application, submit PE -seal `No Rise' Certificate, prepared by a professional engineer licensed to practice in the state of Virginia. 7. Related to 4, 5, 6.d. -e., provide with preliminga plat required information listed at 14-302.B.9, including elevation of lowest floors of proposed structures, and USGS vertical datum shown and/or correlated to plat topography. Show proposed elevations. Preliminary plat lacks proposed contours, without which, it is not possible to evaluate potential impact to preserved slopes, stream buffer, floodplain /floodway. 8. Note: If VDOT and Albemarle County Agent /Commission approve Request for Exception (Section 14- 404.A), a Road Plan is not required since entrances to subdivision will be, in effect, shared driveways fronting Rio Road, separated by approximately 50'. 9. With preliminary plat, provide easements (with dimensions) required at 14-302.A.4, -5, -6. 10. Note: Preliminary plat (conceptual design) requires approval of Request for Exception (Section 14-404(A)). Request submitted as letter d. 8/24/18. With final plat & WPONSMP 11. Show and label floodway and floodway fringe (see VFRIS image, below). 12. Note: Stream buffer crossing Rio Road is not considered stream buffer for ordinance purposes. Rio Road is manmade hardscape with no runoff limiting capacity. Applicant may view Meadow Creek stream buffer crossing Rio Road from the west as irrelevant, with no influence or effect on design. County GIS — preserved steep slopes (green); stream buffer (salmon); floodplain (blue). Note: Area that is not in steep slopes, stream buffer, or floodplain is white /unshaded.

'Alley. The term "alley" means a form of vehicular travelway providing access to the rear and/or side lot line of abutting properties which front along streets. An alley is privately owned and maintained, is intended to be used primarily by the owners and occupants of the abutting properties and persons and vehicles providing services to those properties, including emergency services vehicles, and is not intended for through traffic. An alley is not a "private street." 2 Shared driveway. The term "shared driveway" means a vehicular access to only two lots which have frontage on a street and which are authorized pursuant to section 14-236. a Street, private. The term "private street" means any street or other way or means of vehicular access approved as a "private street' pursuant to sections 14-232 through 14-235 or as a "private road" under any prior ordinance regulating the subdivision of land, that is not designed, constructed, bonded or approved to be maintained by the Virginia Department of Transportation as part of the secondary system of state highways, regardless of ownership. Any street identified on a recorded plat as a restricted road, access road or other designation which was not approved by the county as a private street or a private road as described herein is not a private street. 1 Memorandum To: Justin Shimp From: Christopher Perez, Senior Planner Division: Planning Date: July 2, 2018 Subject: SUB2018-97 Rio Vista - Preliminary Subdivision Plat The County of Albemarle Planning Division will grant or recommend approval of the Subdivision Plat referenced above once the following comments have been addressed: [Each comment is preceded by the applicable reference, which is to the Subdivision/Zoning Ordinances unless otherwise specified.] 1.
