The level spreader has been removed from the plans. Underground detention
provided and release directly to the river via conveyance pipes.
c. 14 Apr 2020 ZMA Application Plan, sheet 20, Note 2 states: `If permitted under
applicable stormwater regulations, stormwater discharge may be to level spreader
or similar facility to open space. If conditions do not permit such discharge,
stormwater may be conveyed to the stream or river in an adequate channel (shown
in gray) with slope stabilization as applicable, where stream bank disturbance
occurs.' Conditions likely do not permit ELS; with WPO plan, ensure proposed
drainage /SWM meet VDOT BMP Clearinghouse Min. standards, design criteria,
etc. A possible alternative to ELS is detention pipe along site access /travel way,
with gradual release of detained flow via storm pipe down /across preserved
slopes to stream, or river. Also, item 2.b., above.
The level spreader has been removed from the plans. Underground
detention provided and release directly to the river via conveyance pipes.

a. Show /label ACSA sanitary sewer /water line easements.
b. Label all retaining walls. Assign Wall identifiers (letter, #) for ease of
reference. Provide TWBW elevations.
Retaining walls have been labeled and identified with letters.
TWBW elevations to be provided. See Sheet C12, C13 & C14.
a (C11) Provide suitable ditch runout for 6' travelway ditch at U.S. Rt. 29. Design
must avoid and limit potential erosion at U.S. Rt. 29, or other locations. Further,
this point discharge must meet state stonnwater management (stormwater
quantity) regulations.
Design provides sheet flow off route 29 to stream and ditches along new
travelway.
d. (C 12) Engineering prefers design abandon ditch to Rt. 29, and instead, more
nearly approximate design shown on sheets 20 21 of 14 Apr 2020 ZMA
Application plan, which shows no conveyance to U.S. Rt. 29 RW.
Ditch extents no longer reach route 29.
e. (C 13) Revise proposed 340 LF 108" CMP underground detention system which
presents liability, with few if any positive offsets (perhaps less initial expense).
Unless rock precludes multiple smaller systems, installation of proposed 340 LF
9' DIA system will require significant SWM facility easement width (Ref.
912 E. High St.. Charlottesville, VA 22902 1434.227.51401 shlmp-engineenrig.rom
ACDSM Easement diagram, p. 15), which requires, for a system this size, at least
37' wide SWM easement (assume 1' bedding, 3' cover). In the future, when the
system is replaced, there will be no vehicular access to the entire lower parking
area that serves nearly half the Rivers Edge development. Also, should there be
performance issues with a single detention system, there is no backup to treat a
portion of developed runoff. If the proposed single system is bypassed, it is
possible the entire volume of impervious area runoff could route across preserved
steep slopes. ZMA Application plan sheet 19 presents a system approximately
half the length proposed. Propose alternate detention that maintains partial access
to lower parking lot should future circumstance warrant excavation of parking
areas to repair or replace the UG detention system. Consider alternative SWM
design that locates multiple detention practices nearer to residences and upper tier
parking (for example, 4 — 85 LF systems would provide identical detention
capacity without compromising access to this degree, and would permit at least
partial water quantity treatment should incident affect one of several systems. As
it is, incident affecting a single system may prevent or compromise storm
detention, entirely. Engineering disapproves current proposed SWM design on
access /maintenance basis, as well as scale of departure from ZMA Application
plan. With WPO plan, provide bypass of any SWM facility while mitigating
impact of bypass flow to critical resources, especially preserved steep slopes.
The proposed detention system has been broken up into 2 separate sections
that will allow for maintenance and replacement of 1 section while still
providing access and parking in the lower section.
Provide CG-6 or CG-7 along site access/travel way wherever storm runoff
concentrates against curb. If ZMA approval explicitly exempts site from curb -
gutter requirements at Ch. 14 /18, please direct Engineering to exemption.
Otherwise, please see 18-32-7.2.2.a. / 14-412.B.; provide curb with gutter. [Note:
sheets 20-22 of ZMA Application plan show inlet design along site access.]
The ZMA appears to shows roadside ditches to DI-7 grate drop inlets (not
curb/gutter). Ditches are provided all along the road sides and include a 2-ft
shoulder. A 2-ft shoulder was chosen to minimize disturbance of steep slopes.
Further, the road entrance has been relocated and as a result provides for
much less steep slope disturbance. This comment was discussed with John
Anderson during a meeting on November 11, 2022 and was resolved to be
appropriate to provide ditches to grate drop inlets.
g. Provide PE -sealed sanitary effluent pump station design, incl. pump curves, pump
type, wet well design, alarms, remote sensing, etc. as provided with documents or
during presentation to PC or BOS in 2020, or in /with ZMA documents, etc.
Recommend furnish evidence of coordination or approval with or from DEQ,
relative to sanitary pump station design. Albemarle will not review or approve
pump station design. ACSA is unlikely to review or approve pump station design.
It is incumbent upon developer (per approved ZMA) to obtain approvals needed to
construct the pump station, to ensure remote sensing system is operational, and
that station will be maintained.
PE -sealed pump station plans to be provided with future submittal.
912 E. High St.. Charlottesville, VA 22902 1434.227.51401 shlmp-engineering.rom
C 15: Show proposed storm lines and utilities (sanitary sewer/water) in light line -type on
this sheet, to highlight potential conflicts. For example, proposed storm lines are
proposed to cross at least 5 parking islands proposed to be planted with large canopy
species. Revise storm pipe locations to avoid landscape conflicts.
Utilities are now shown on the Landscaping Plan Sheet C23 of the Final Site Plan.
Utilities have been located to avoid the tree planting areas in landscaping islands.
8. Ensure steep slopes disturbance is consistent with sheet 23, 14 Apr 2020, ZMA
Application, and does not exceed 39,100 sq. ft. approved with ZMA. Show /label Area
(ft) of Preserved Steep Slope impact with WPO and FSP.
The Preserved Slopes Disturbance has been updated to a total of 27,254 sf. See
Sheet C6 of the WPO plan. & Sheet C6 of the Final Site Plan.
9. Ensure stream buffer disturbance is consistent with sheet 24, 14 Apr 2020, ZMA
Application, and does not exceed—23,000 sq. ft. approved with ZMA. Show /label Area
(ft') of stream buffer impact with WPO and FSP.
Stream Buffer Disturbance is outlined on Sheet C26 of the Final Site Plan.
10. C14: Public drainage easement (downstream of SWM) should not propose storm pipe
beneath /through a retaining wall. If unavoidable, provide concrete headwall /lintel details
with PE -seal, similar to Versa-LokTM standard. Comment does not anticipate approval of
public drainage easement with pipe penetration beneath or through a retaining wall, a
configuration to avoid.
A grass slope has been provided to replace the section of wall at the public drainage
easement and pipes no longer run below retaining walls.
11. C 16: Include Site Access (travelway) section with stone /pavement depths; see River's
Edge Street Section, sheet 28 of ZMA Application plan. Provide site access pavement
design based on full buildout ADT.

We recommend providing three (3) candidate names for each road to our office for review, in
case your first choices are not acceptable.
Before final plans are submitted, please add 4 road names to the plans for the new travel ways
and locations of proposed structures. The existing road names, Rivers Edge Road and Rivers
Edge Lane can be used again, however there will need to be new roads names for the 2 additional
road ways that serve the new proposed structures. For example, Rivers Edge Road could be used
as the main entrance accessing Route 29. Rivers Edge Lane could be used for proposed
structures 1 — 10. A third road name will need to be created for structures 11 —18 and a fourth
road name will need to be created for proposed structures 19 — 34.
Road names have been provided on the plans. Rivers Edge Road, Rivers Edge Lane, Rivers
Edge Way, Riverview Lane.

separate submission of a plat).
Public access easement provided on plans.
2. ZMA201800018: Please clarify if the "Future Pedestrian Connection" bridge across
Flat Branch shown in ZMA201800018 will be provided (constructed) by
owner/developer.
The owner/developer is not providing the "Future Pedestrian Connection"
bridge across Flat Branch. A public access easement is proposed to provide
access to this crossing that would be constructed should the neighboring
property be developed.
3. Please provide a detail and/or notes for the "New Paved Pathway" that is proposed
to "Connect to Future County Trail Network."
A cross-section detail has been provided on Sheet C19 for the Paved Path.

4. Advisory comment / recommendation: To help facilitate the planned future greenway
along the North Fork Rivanna River, please consider voluntarily providing an
additional small greenway easement (or other similar public access easement) on the
northwestern side of the subject property, over the riparian slopes that are located
between US-29 and the existing structure to be preserved (2256 Rivers Edge Lane).
That additional easement area would provide a complete connection across the subject
property, from the "Future Pedestrian Connection" across Flat Branch to the VDOT
ROW under the US- 29 bridges; and would help enable the County's future
construction of the planned greenway connections along the North Fork Rivanna River
between the UVA North Fork Research Park and downstream areas.
Public access easement provided from new travelway to below the route 29 bridge
and from the new travelway to the future pedestrian connection.
5. Advisory comment / recommendation: To help support the public's use of the planned
future blueway (water trail) on the North Fork Rivanna River, please consider
determining the feasibility of voluntarily dedicating any additional small greenway
easement area(s) in one or more strategic locations along the subject property's 1.0
miles of frontage on the North Fork Rivanna River. Such additional easement areas
would provide paddlers and other water trail users with formal permission to take a
break from paddling; and would accommodate temporary daytime recreational use of
the riverfront (if appropriate riverfront sites exist, without being incompatible with the
planned private uses and improvements of the subject property).
No voluntary dedication of greenway easements are proposed along the river.
