SDP - 2008 -00086 Willow Glen Final
The Planner for the Zoning & Current Development Division of the Albemarle County Department
Community Development will approve the final site plan when the following items have been
satisfactorily addressed. (The following comments are those that have been identified at this time.
Additional comments or conditions may be added or eliminated based on further review.) [Each
comment is preceded by the applicable reference to the Code of Albemarle.]
Proffers: Per proffer #1; 15% of the dwellings units are to be designated as affordable. 35 is
the magic number (232 X 15% = 34.8 or 35). Provide a table that breaks down the number
of affordable units in each phase making sure that each phase contains a minimum of 12% of
the units in that phase designated as affordable.
2. [18- 32.5.6 b] Sheet 2: "Site Specific Notes" - #13 provides a condominium breakdown that
appears to be more than what is shown in the parking table.
3. [18- 32.5.6 b] Sheet 2: "Property Size" — It appears that it should be 23.681 AC
4. [18- 32.5.6 b] Sheet 2: "Project Data" Total # of Units/Density — It appears that it should be
232 Units = 9.80 DU /AC
5. [18- 32.5.6 b] Sheet 2: "Breakdown" — The pervious /open space should be shown as
individual areas and percentages.
6. [18 -4.12] Sheet 2: "Parking Data" — The total required for the townhouses with 1 car garages
should be 40 not 41. This would make the total required 470.
The total provided for the townhouses with 2 car garages should be a total of 144 not 108. 2
cars plus 1 in the driveway. 48 X 3 = 144. Also, there actually appears to be 11 additional
spaces not 9. This would make the total provided 524.
7. Sheet 2: - "Trip Generation" The number of single family detached should be 22 and the
other number should be 210
8. [18- 32.7.2.8] Sheet 5: Note that phase 1 will be built first and that all of the other phases can
be built in no particular order.
At the southern corner of the amenity pond in Phase 1 the entire pond and path should be
included in Phase 1 going around the path.
A portion of the parking of Phase 8 appears to be in Phase 1. Not sure why.
Unit 99 appears to be split by the phase line between Phases 1 and 8.
Include the 1/2 basketball court in Phase 5 since that is when the number of units would go
over 100. If the phasing does not proceed numerically then be aware that the 1/2 basketball
court needs to be provided when 100 units is reached.
9. [18- 32.5.6 n] Sheets 7 -11: Provide crosswalk hatching in the roads at all appropriate curb
cuts along the public and private streets. 12 locations on Sheet 7, 4 locations on Sheet 8, 7
locations on Sheet 10, and 3 locations on Sheet 11.
10. [18- 32.7.2.8] Sheet 7 and 8: Provide sidewalk along the frontage of Dickerson Road. The
portion on Sheet 8 should be connected to the sidewalks already shown on Sheet 8. All
sidewalks should be shown built to the property lines.
11. [18- 32.5.6 m] Sheet 7: Provide the distance to Airport Road since that is the closest existing
intersection. Townwood Boulevard is not in existence yet, so do not refer to that as being the
closet intersection.
12. Sheet 7: "Minimum lot and yard requirements" — The table is taken from the rezoning where
the types of units are shown. That same labeling is not used on the site plan. Please correct
to have the lot numbers correspond with the unit types.
13. Sheet 9: Buildings E and F appear to have parts of the building that are in the 20' perimeter
setback.
14. [18- 32.7.2.5] Sheets 7, 8, 19, 20, 38, 39, 44, 45, 51 and 52: Show the interparcel connection
being made on all of the appropriate sheets. This will remove the tot lot and landscaping
through what will eventually be the interparcel connection to TMP 32 -56. To avoid any
confusion in the future Albemarle County is asking that this plan show the interparcel
connection being shown on this plan. There may be some ROW issues that engineering may
comment on but we feel that they can be resolved by shifting the buildings slightly.
15. [18- 32.5.6 n] Sheet 22: There appears to be a wall stretching behind Lots 41 -44 that is not
labeled.
16. [18- 32.5.6 n] Sheets 19 -23: All retaining walls need to be labeled consistently. Some do not
appear to be labeled and others are missing information.
17. [ 18- 32.7.9.4] A conservation plan needs to be provided for the preserved tree areas that are
being shown on each page of the landscape plan
18. [18- 32.7.9.9 c] Sheet 38: The canopy calculations cannot include both the open space credit
and the recreation and preservation credits since the recreation area and the preservation
areas are shown within the open space. Deductions shall be cumulative but shall not be
duplicative.
19. [18 -4 -16] The amount of recreation area appears to be OK. The number of tot lots does not
appear to be OK and the number of 1/2 basketball courts does not appear to be OK.
The requirement for tot lots is 4. The 202 townhouse and condo units are used for this
calculation. (1 for the first 30 units and 1 for every 50 units. 202 units -30 = 172. 172/50 =3).
The requirement for 1/2 basketball courts is 2. The 202 townhouse and condo units are used
for this calculation. (1 for every 100 units. 202 units = 2 courts)
All tot lots should have the appropriate fencing around them if adjacent to travelways.
20. [18-32.5.6 1 and [ 18- 32.7.5] Provide utility easements for other utilities that will be provided
to the units.
21. It is recommended that the landscaping around the 1/2 basketball court enclose the entire area
Please contact me at your earliest convenience if you have questions or require additional
information.

COUNTY OF ALBEMARLE
Department of Community Development
To: Francis MacCall, Planner
From: Amy Pflaum, Engineering Review
Subject: SDP- 2008 - 00086, Willow Glen Final Site Plan
Date received: 27 May 2008
Date of Comment: 16 June 2008
The final site plan for Willow Glen has been reviewed. A full review of the stormwater management and
erosion control plans are pending. Before Engineering can recommend approval, the following items must
be addressed:
A. General Review Comments
1. Please provide copies of federal and state permits for wetland and stream disturbance
(Army Corps, VDEQ, etc.).
2. Please revise the note on Sheet 11 regarding the connection to Towncenter Drive to read
"...permission of the COUNTY ENGINEER should a more... ". This will correspond
with Proffer #3 on Sheet 2.
3. Please provide all copies of necessary offsite easements on adjacent parcels, including
TMP 32 -46 and TMP 32 -50. These easements include, but are not necessarily limited to,
road construction and drainage easements.
4. Please add the Deed Book & Page numbers to the existing 30 foot electric easements
which are to be removed or relocated.
5. This plan removes the existing entrance to parcel TMP 32 -49B from Dickerson Road and
does not provide for its relocation.
6. This plan does not provide for future inter - parcel connectivity to parcel TMP 32 -49B
from within the site.
7. Please label proposed retaining walls with maximum wall height. Please provide details
for retaining walls. Safety railing is required on walls over 4 feet high. Guardrail is
required for retaining walls adjacent to parking or travelways, as well as roads over fill
slopes or culverts.
8. There are areas of hatching on the Layout Plans that are not labeled with the type of
easements to be dedicated in those areas. Please add labels.
9. Please submit architectural elevations and drawings showing the proposed parking
structure.
10. This WPO plan is currently being reviewed independent of the site plan. Additional
WPO comments may be given in the reviews to follow.
B. Streets, Parking, and Circulation Review Comments
1. VDOT approval is required for any work affecting the public right -of -way.
2. Please revise parallel parking spaces to meet the requirement of 9 feet wide by 20 feet
long.
3. Should all the parking spaces under Buildings A, B, and D be full, is there sufficient
space for a vehicle to turn around in the travelway? Please demonstrate that there is
Albemarle County Community Development
SDP - 2007 -00065 Waiver Requests
Sheet 2 of 2
sufficient space, or add a turn around at the end of each travelway.
4. This site plan proposes several `dead -end' parking lots. If these lots are full, it will be
difficult for a vehicle searching for a space to turn around. It is recommended that these
parking lots be revised to provide connectivity or that turn - arounds be added to the ends.
5. Please demonstrate how a garbage truck will turn around after accessing the dumpster at
the northwest corner of Building D (Lot 84).
6. If all parking spaces are full in the lot to the east of Building B (Lot 2), how will a
garbage truck turn around after accessing the dumpster?
7. To access the dumpster next to Lot 98 on Trudeau Court, a garbage truck will have to
block its travelway.
8. Please include a dumpster pad detail or specification per the Albemarle County Design
Standards Manual.
9. Please revise the grade of the parking lot to the east of Building B (Lot 2) to be 5% or
shallower.
10. Please revise the sidewalks to the east of Buildings A & B to be 6' wide, or add bumper
blocks to the abutting parking spaces.
11. The radius is not labeled at the eastern entrance of Trudeau Court onto Prestwick Glen
Drive. The parking for lots 97 & 98 being in such close proximity to this entrance may
present a safety issue. Parking places must be separated from entrances and streets a
minimum of 18' from the back of the entrance radius.
12. The public /private boundary between Prestwick Glen Drive and Trudeau court is
awkward. Why not continue the private ROW of Trudeau Court through the intersection
and cut Prestwick Glen's public ROW shorter?
13. The street section details are referenced incorrectly on the Layout Plan sheets. The
sections for Roads A through F are on Sheet 16, not Sheet 17. Please revise the detail
references.
14. The right -of -way of Prestwick Glen Drive is 63 feet, however the width available for a
"future interparcel interconnection access easement" is 58 feet. In order for Prestwick
Glen to maintain the same road section, a sidewalk easement will be required in Lot 14.
15. In order to avoid future conflict, it may be appropriate to build this connection with this
plan.
16. Tempelhof Court is spelled incorrectly on the profile sheets.
17. I am unable to find a curve table for the horizontal curves on the street centerlines. Please
provide horizontal curve radii.
18. Please show cross -drain locations, labeled with VDOT designations, at every major cut
and fill transition or sag curve.
B. ESC Plan Review Comments
1. Please provide a copy of the written agreement between Willow Glen and the owners of
the "Sediment/SWM Basin by Others" that allows Willow Glen to utilize this basin for
sediment trapping purposes. Also, please verify that this basin has been sized to include
the portion of Willow Glen that will drain to it.
2. The Erosion Control Narrative describes the demolition of and clearing around an
existing home on the property during Stage 1. This structure is not pictured or otherwise
identified on the Erosion and Sediment Control Plan Stage 1.
3. The location of the proposed logging trails described in the Narrative are not shown on
Albemarle County Community Development
SDP - 2007 -00065 Waiver Requests
Sheet 3 of 3
the Plan.
4. A diversion dike may be necessary along the boundary between Zone A and Zone C,
depending on the timing of installing the diversion dike proposed within Zone C. If
grading commences within Zone A prior to perimeter controls being established within
Zone C, exposed soil may erode from Zone A into Zone C, unless a diversion dike is in
place.
5. The diversion dikes proposed in Zone B appear to direct run -off around Sediment Trap
#1, instead of into it.
6. The maximum allowable drainage area to a diversion dike is 5 acres. Drainage areas
larger than 5 acres may require a diversion designed per VESCH STD & SPEC 3.12.
7. Please also provide safety fence with sign around the sediment traps.
8. These comments do not encompass a full WPO application review. A more thorough
review of the Erosion and Sediment Control Plan will be done on the WPO submittal of
this project.
C. SWM Plan Review Comments
1. Please provide a copy of the written agreement between Willow Glen and the owners of
the "Stormwater Management Basin by Others" that allows Willow Glen to utilize this
basin for water quality and quantity purposes. Also, please verify that this basin has been
sized to include the portion of Willow Glen that will drain to it.
2. The minimum standard width for drainage easements is 20 feet. Depending on the size
and depth of the proposed storm sewer pipe, an easement may need to be wider. Please
check your easement widths using the formula and detail in the Albemarle County Design
Standards Manual.
3. Drainage easements are not shown on Sheets 22 and 23.
4. No structures or trees are allowed within drainage easements.
5. Please provide adequate vehicular access to and permanent stormwater management
easements around the proposed bio- filters, bio - swales, and bio- detention basin. Adequate
access is 10 feet wide, not exceeding 20% in grade. For grades in excess of 10 %,
graveled access is required.
6. Please provide adequate access to and permanent stormwater management easements
around the stormwater management pond, its riser structure, and the 2 forebays.
Adequate access is 10 feet wide, not exceeding 20% in grade. For grades in excess of
10 %, graveled access is required.
7. The piping of the stream under Trudeau Court is labeled as a 48" culvert in the plan
views and on Pipe C's profile where it crosses under this storm sewer. This does not
correspond to its label as a 48 "x96" arch pipe in its own profile, and to the calculations
on Sheet 25. Piping this stream is a significantly important piece of this development,
please clarify what this pipe is to be. Please also show the crossing of this pipe in the
street profile of Trudeau Court.
8. Please provide overland relief for proposed inlets A -4 and A -5 in case of clogging. The
failure of any system should not cause structures or yards to floods.
9. Structure C1 -2 is shown and labeled as a STD MH -1. This structure is the upper -most
structure of the proposed pipe run, however, a manhole will not collect any flow. Please
explain the necessity of this manhole and its outlet pipe.
Albemarle County Community Development
SDP - 2007 -00065 Waiver Requests
Sheet 4 of 4
10. Please provide a detail for the storm sewer pipe from Shannon Glen Court to Forebay #2
as it goes through the proposed wing wall of the bridge.
11. Please provide a detail for the storm sewer pipe from Tempelhof Court to the bio-
detention basin as it goes through the proposed retaining wall.
12. Safety slabs (SL -1) are required for any structure greater than 12 feet deep.
13. Table 7 on Sheet 26 references inlets A5 -5, A5 -6, and A5 -7, these inlets do not exist in
the plan or profiles.
14. Provide outlet protection computations for all outlets.
15. A baffle may be necessary in the Amenity Pond between the inlet of Forebay #2 and the
pond's outlet structure to assure that the flow is not short circuiting.
16. The trash rack over the riser crest may not be flat (no DI -7), please specify a different
trash rack.
17. Will there be 6 or 8 orifices on the pond outlet structure? There appears to be a
discrepancy in the detail labeling on Sheet 34. Also, are these orifices really to be 2 feet
long, 50% of the 48" length of the side of the structure?
18. A fence is required at or above the maximum water surface elevation when a basin slope
is a vertical wall.
19. Show and label the 10 -yr and 100 -yr water surface elevations on all facility cross
sections.
20. It appears that the flow in the Bio- Detention Basin may short circuit.
21. Please dimension the base of the Bio- Detention Basin riser structure on Sheet 35.
22. Label the minimum floor dimensions of the bio- filters.
23. Please revise Note 2 on the cross section of Bio- Filter #1 to say "The distance between
clean-outs will not exceed 50 feet."
24. The riser crest and invert elevations shown on the outlet structure detail for Bio- Filter #1
on Sheet 36 are incorrect, please revise.
25. The downstream slope of Bio- Filter #2 should be 3:1 or flatter, and labeled as such.
26. Please move Bio -Swale #1 as far outside of the lots as possible.
27. These comments do not encompass a full WPO application review. A more thorough
review of the Stormwater Management Plan will be done on the WPO submittal of this
project.
