For preliminary plat approval
Cl
1. Provide PE -seal signature and date with subsequent submittals, no later thanfinal preliminary subdivision
plat submittal (condition of preliminary plat approval).
C2
2.
3. Provide Orchard Drive public right-of-way deed bk.-pg. reference.
4. Visually confirm existing site topography is consistent with 2018 Albemarle County GIS. Revise Source
of Boundary and Topography text, C 11 to include date of (at least) visual confirmation of topography.

5. Subdivision plat appears to propose a boundary line adjustment (BLA) that combines TNT parcels 05500-
00-00-068CO and 05500-00-00-068D0. Provide linework, notes, or separate BLA application for boundary
line adjustment required for preliminary subdivision plat to proceed. Engineering defers to Planning.
6. This sheet proposes a parking lot, not a private street or public road which would appear to be required for
subdivision. Whether Planning Div. is prepared to approve this design, relative to ordinance requirements,
Engineering defers, but requirements that apply to subdivision (public road /private street access) would
appear nonoptional. Were this a site plan only, different code section concerning site (vs. lot) access would
apply, but this is a subdivision under Chapter 14. Street requirements appear to apply, much as they
applied to recent relatively complex Timberwood Square development, which includes a site plan, road
plan, and final subdivision plat. Engineering recommends revised preliminary subdivision plat make
explicit reference to lot access requirements (road /street) that appear under chapter 14, since proposed
preliminary plat provides neither a public road nor a private street design that connects with Orchard Drive.
7. Unit 4 appears to cross a proposed lot line. Please revise linework, as needed.
8. Typ. 16' L parking space requires 2' unpaved strip between back face of curb and 5' sidewalk. Revise per
p. 17 ACDSM ( link: httos://www.albemarle.orgjHome/ShowDocument?id=270 )
9. New stormwater conveyance channel appears to indicate compliance strategy of discharge without
detention or retention. It is difficult to discern quantity or quality strategy with proposed preliminary plat.
Note: DEQ has notified Local Program Authorities that channel protection requirements listed at 9VAC25-
870-66 that make use of manmade conveyance that discharges to a natural receiving stream, must, at point
of discharge (even if discharge is at 1% limit of analysis) meet energy -balance channel protection
requirements. Please contact Engineering for more detailed information [Erin Belt, DEQ, email: June 1,
2020 3:21 PM email]. Revise preliminary plat with schematic details, notes, labels, and/or narrative that
clarify how pre -developed forest /post -developed impervious areas meet SWM quality (9VAC25-870-65)
and quantity requirements (9VAC25-870-66). Preliminary plat must include conceptual SWM design that
does both.

10. Show proposed grading north of 5100sq.ft. parking area required to construct parking area. No proposed
grading is shown, grading appears necessary to construct the parking area.
11. Revise preliminary plat to include narrative description /rationale of stream buffer grading and tree removal
which appear impermissible, as proposed. Proposed grading and native vegetation removal appear not to
be listed (impermissible) under 17-602, -603, -604. A 6-lot subdivision on 0.64 Ac. combined parcel area
outside the stream buffer, absence of subdivision road /street appear to exceed limits of both chapter 17
(stream buffer) and chapter 14 (lot access) requirements. Engineering defers to Planning on lot access
requirement (appears to be required, it was for Timberwood Square), but directs applicant to review chapter
17, Article VI, Stream buffers, for improvements and activities exempt from duties to retain, establish, or
manage a stream buffer; types of structures, improvements and activities authorized in a stream buffer
(proposed grading is not), and types of structures, improvements and activities which may be allowed in a
stream buffer by program authority (items A.-F.). Grading to support proposed 6-lot subdivision exceeds a
reasonable interpretation of `reasonable use of the [combined] lot.' Engineering does not object to 6-lot
subdivision, only impermissible activities within stream buffer limits. Engineering also draws attention to
SWM quality /quantity requirements, and lot access requirements (comments elsewhere).

12. With SWM-related information provided at item 11, above, with revised preliminary subdivision plat,
please provide table that displays existing ground cover and proposed post -developed ground cover.
Please feel free to call if any questions.
