The Halifax House Initial Site Plan has been reviewed by Engineering. The following comments will
need to be addressed with the final site plan (or with plans submitted prior to FSP):
1. [17-604.A.] Mitigation plan plantings are required for development within the landward 50' of the
stream buffer. Proposed parking within the landward 50' of buffer was discussed and Engineering
signaled acceptance during pre -application meeting (PREAPP202100060), 8/9/2021, county engineer
in attendance. Please note mitigation (plan) planting requirements at 17-604.C.5. apply.
2. Recommend sheet L 1.0 repeat with sheet title revised to `Mitigation Plan' (with WPO plan submittal),
and that planting density meet requirements listed at 17-604.C.5.

3. Please ensure that seven (7) grass paver parking spaces proposed within landward 50' of stream buffer
persist as a design feature in the final site plan since grass pavers mitigate stream buffer impact by
aiding infiltration.
4. FSP approval requires WPO plan approval; please submit WPO Application at earliest convenience.
5. C3.0: Coordinate tree removal with Planning. Tree removal is limited within 15-ft of perennial
streams in any zoning district [18-4.3.b.1]. Engineering defers to Planning.
6. C4.0
a. Recommend bumper blocks for parking spaces proposed to front knee wall at bottom of slope
to prevent vehicle /wall damage.
b. Recommend label clarify asphalt paved (or brick -paved) HC parking /loading space are
proposed since gravel is inappropriate for HC parking (access /loading).
7. C4.1: Riprap stone outfall and light grading proposed for outfall of Str. 3 will be evaluated with WPO
plan. Grading required to establish non -erosive gradual outfall to tributary to Little Ivy Creek is
permissible (17-603.13; also `water dependent facility' at 18-3), but must be held to a minimum, with
special precaution taken with equipment operating near the stream edge to ensure no equipment -borne
petroleum contaminants enter the stream. Equipment below stream OHW or within the stream are
impermissible unless coordinated with /through jurisdictional agencies, including DEQ, USACE, etc.
8. C5.0 - Site Utility Layout appears to concentrate stone runoff without detention prior to release to
trib. to Little Ivy Creek. Storm discharge to this stream must meet state stormwater management
water quality requirements at 9VAC25-870-65 (clearinghouse BMPs), or alternatively, 9VAC25-870-
69, Mite compliance options; and water quantity requirements at 9VAC25-870-66.B.3 (energy
balance). SWM design will be evaluated with WPO plan and requires revision to layout on C5.0.
