Subject: SUB 2013– 00030 Westlake Hills – Phase I Road Plans
The County of Albemarle Planning Division will recommend approval of the Road Plans referenced above once the
following comments 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, which is to the Subdivision/Zoning Ordinances unless
otherwise specified.]
1. [Comment] This application was not submitted for subdivision plat review; comments provided are for Road
Plans only. However, for future reference, it does appear that the number of Phase I lots noted exceeds the
allowable density.
Rev1: Comment not fully addressed. This comment is applicable to any plat submittal. The density
calculation now appears to be approvable, however it seems a portion of the area added to Phase I
includes a change in the southern boundary of TMP 56-95B. This boundary line no longer matches
what is shown on County GIS and must be verified by plat.
Rev2: Comment addressed on most recent plat submittal.
2. [13.4.1] Environmental standards. Street trees are required to be shown on the road plans for this
development to meet the bonus factor approved with the preliminary plat that allowed for a smaller minimum lot
size and a smaller frontage requirement. It appears that many of the proposed tree locations have conflicts
with proposed utilities; these conflicts should be resolved before the plan is approved.
Rev1: Comment addressed.
Rev2: Comment not addressed. With this revision submittal, there are once again several conflicts
between street trees and utilities; these conflicts should be resolved before the plan is approved.
Additionally, the Eastern Connector only has street trees on one side and only for a portion of that
side; street trees should be provided on both sides of the proposed road for its entire length.
Rev3: Comment not fully addressed. Since the new Landscape and Maintenance Easements should be
for the benefit of the Developer/Westlake Hills HOA to maintain the street trees, no easements are
necessary where the trees are in the open space that will also be held by the HOA; please remove these
easements. The associated plat must also show all easements. A maintenance agreement for the
proposed landscaping within the easements must be submitted for review and approval prior to
approval of the plat.
3. [14-302(A)9 & Condition of Preliminary Approval] Building sites on proposed lots. The Board of
Supervisors approved a critical slope waiver request for this subdivision. An overlot grading plan must be
submitted as a condition of approval of this waiver.
Rev1: Comment not addressed. The grading plan shown on Sheet 6 does not meet requirements for an
overlot grading plan. Please coordinate with Engineering.
Rev2: Comment addressed.

4. [14-302(B)3 & Condition of Preliminary Approval] Public areas, facilities or uses. Coordinate with the
Department of Parks and Recreation to establish the exact location of the greenway area and any other
facilities as noted in the Comprehensive Plan. Please refer to comments provided by Parks during preliminary
plat review.
Rev1: Comment in progress; coordination with Parks underway.
Rev2: Comment addressed.
5. [Comment] The plant count provided for Thuja occidentalis appears to be incorrect; please verify and revise.
Rev1: Comment addressed.
6. [Comment] This subdivision is not subject to the tree canopy requirement. The adjoining property owners and
future residents of Westlake will benefit from as much tree canopy and existing tree preservation as possible,
but the requirement listed on the landscape plan isn’t applicable to this application.
Rev1: Comment addressed.

Re: SUB- 2013 - 000130 Westlake Hills Subdivision, Phase 1
Dear Mr. Koslow:
We have reviewed the road plans entitled Westlake Hills Subdivision, Phase 1 dated 2/28/13 with
revisions dated 5/20113, 7131113, and 829113 and offer the following comments:
1. Prior review comments identified in a letter dated June 24, 2013 appear to have not been
addressed with this submittal. A copy of the June 24 review letter has been attached with this
review letter.
2. Guard rail warrants should be checked for the sections of the Eastern Connector Road and
Guadalupe Drive near the stormwater management facilities.
3. On Sheet 4, the sight line for the intersection of Colorado Road and the Eastern Connector Road
needs to originate 14.5' from the edge of the nearest travel lane.
4. On Sheet 4, the sight line for the intersection of Guadalupe Drive and the Eastern Connector
Road needs to originate 14.5' from the edge of the nearest travel lane.
5. A sight line easement will be needed across 10 for the intersection of Lavaca Court and
Guadalupe Drive. This easement should be 5' beyond the sight line shown.
6. On Sheet 8, the pipe numbers for the storm sewer along Lavaca Court and along Guadalupe Drive
between Colorado Road and the Eastern Connector Road should be added to the plan view.
7. On Sheet 8, the type of DI and length of slot opening for structure 68 should be added to the plan
view.
8. On Sheet 8, the contours indicate that runoff will flow toward the middle of the travel lanes of the
Eastern Connector Road at the intersection of with Guadalupe Drive. This needs to be looked at
closer and revised as necessary so that runoff is directed towards the curb and gutter.
9. On Sheet 13, CD -1's should be shown at the lower end of cut slopes as indicated in the 2008
Road and Bridge Standards.
10. On Sheet 13, the vertical curve (crest) shown between stations 9 +29.09 and 12 +39.09 does not
meet the minimum K -value as indicated in Appendix F of the Road Design Manual.
11. On Sheet 13, the vertical curve (sag) shown between stations 13 +11.34 and 18 +11.34 does not
meet the minimum K -value as indicated in Appendix F of the Road Design Manual.
12. On Sheet 13, the vertical curve (sag) shown starting at station 22 +44.34 does not meet the
minimum K -value as indicated in Appendix F of the Road Design Manual.
13. On Sheet 15, CD -1's should be shown at approximately stations 20 +25 and 23 +50.
14. On Sheet 19, a note should be added indicating that ST -1 steps are required for all structures that
have a depth of 4' or greater.
15. On Sheet 19, to profile for the storm sewer from structure 42 to structure 38 is mislabeled.
16. On Sheet 20, a note should be added indicating that ST -1 steps are required for all structures that
have a depth of 4' or greater.
17. On Sheet 20, structure 88 should be moved and/or lowered so that the base rests on virgin soil.
18. On Sheet 21, a note should be added indicating that ST -1 steps are required for all structures that
have a depth of 4' or greater.
19. On Sheet 21, structures F52 and F52B should be moved and/or lowered so that the bases rest on
virgin soil.
20. On Sheet 21, the profile for storm sewer pipe F57 is mislabeled.
21. On Sheet 21, storm sewer pipe F57 will require anchoring due to the steepness of grade.
22. On Sheet 22, the upstream and downstream inverts for the pipe between structures 6 and 4 do not
match those shown in the profile.
23. On Sheet 22, the downstream invert for the pipe between structures 14B and 14 does not match
that shown in the profile.
24. On Sheet 22, structure 38 in the Drainage Descriptions table is shown as a manhole when it is
actually a DI -3B with L = 6'.
25. On Sheet 22, there are several sections of pipe that have velocities greater than 10 fps. These
sections of pipe should be adjusted where possible so that the velocities are less than 10 fps.
26. On Sheet 23, the length of the pipe between structure 66 and the outlet does not match the length
shown on the profile. This should be corrected so that the velocity in this section of pipe can be
verified.
27. On Sheet 23, the length of the pipe between structures 78 and 68 does not match the length shown
on the profile. This should be corrected so that the velocity in this section of pipe can be verified.
28. On Sheet 23, structures 75, 74D, and 74B are shown as DI -313's in the Drainage Description
table but are shown as DI -3C's in the profiles.
29. On Sheet 23, the rim elevation of structure 78F is different in the Drainage Description table
from that shown in the profile.
30. On Sheet 24, the rim elevation of structure F58 is different in the Drainage Description table
from that shown in the profile.

Project: Westlake Hills (Phase 1) – Road Plans SUB201300030
Plan preparer: Collins Engineering [434-293-3719]
Owner or rep.: Lickinghole Creek, LLC
Plan received date: 10 September 2013
Date of comments: 16 September 2013
Reviewer: Michael Koslow
Review Coordinator: Michael Koslow
The third submittal of the road plan set (SUB201300030) submitted 5 September 2013 has
received Engineering Review and does not appear to meet Albemarle County minimum checklist
items for approval. This review does not include a review of Erosion & Sediment Control or
Stormwater Management. Please adequately address the following comments for final approval:
A. Application Information
1. Please revise sheet titles on sheets 8 & 9 to reflect intent of these sheets to also function as
an overlot grading plan (e.g. could be titled “Phase 1 Grading Plan and Overlot Grading Plan”)
B. Proposed Plan View Information
1. It appears that sight distance easements are needed for the NE corner of Colorado Road
and Eastern Connector road and the SW corner of Guadalupe Drive and Lavaca Court. Please
include these on sheets 5 & 6.
2. Please indicate striping between proposed NB and SB travel way for Eastern Connector
just north of Colorado Road. Please indicate left turn arrow or combined through-left arrow for
NB Eastern Connector at Jonna Street.
3. Please regrade the end of Guadalupe Drive at the cul-de-sac. Structure #4’s rim should be
the low point to ensure that runoff would not inundate the houses in proposed lots 36 or 37 should
the drainage system fail. Detail grades around the cul-de-sac would suffice.
4. Please include station ticks at minimum 50’ intervals for all proposed public roads
including Eastern Connector Road, Lavaca Court, and Colorado Road on sheets 4 and 5.
5. Please label all proposed drainage pipe runs in plan view (could be on sheets 8 & 9).
Engineering Review Comments
Page 2 of 2
E. Street Profiles
1. Three out of four vertical curves for Eastern Connector Road appear to have substandard
“k” values for 35 mph design speed. Will defer to VDOT regarding geometric standards.
2. Please include cross drains (CD-1,2) at every major cut and fill transition point including
for Connector Road and for Guadalupe Drive near stations 20+00 and 24+00.
3. Please include all utility crossings including water main crossing Eastern Connector Road
near station 21+95.
4. Please include all drainage pipe runs crossing Eastern Connector Road including:
F58B-F58, 74D-74B, F56-F54, F52B-F52, F44B-OUT, F46B-F46, F50-F48, 30-28
5. Please include all drainage pipe runs crossing Lavaca Court including:
78D-78B, 80-78, 70-68
6. Please include all drainage pipe runs crossing Guadalupe Drive including:
76-74, 72B-72, 70B-70, 82-66, 86-84, 90B-90, 92B-92, and 96-94
7. Please consistently label Eastern Connector Road in profile view (i.e. please change the
profile name from “Connector Road” and the notes from “Eastern Avenue Connector”).
F. Drainage Profiles
1. Label on sheet 19 “STR 42 – STR 20” appears to refer to structure 42 – 38. Please revise.
2. Label on sheet 21 “STR F62 – STR F104B” appears to refer to structure F58 – OUT.
Please revise.
3. Please include all proposed utility crossings including proposed water main crossing pipe
81 on sheet 20 and drainage pipe F51 crossing Culvert 13+80 (Eastern Connector Road) on sheet
21.
F. Drainage Calculations
1. Pipe runs from Structures 2 to 1B and from 1B to out appear to have excessive flow
velocities ( > 15 fps). Please redesign these structures to reduce proposed flow velocity to < 15
fps.
2. Please provide calculated flow capacity for pipe run from Structure 68 to 66. It appears
that it could be lower than the calculated flow in a 10 year storm event. If the capacity is less than
the calculated flow, please redesign this pipe run for adequate capacity.

Re: SUB - 2013 -00030 Westlake Hills Subdivision, Phase 1
Dear Mr. Koslow:
We have reviewed the road plans entitled Westlake Hills Subdivision, Phase I dated 2128113 with
revisions dated 5120113 as submitted by Collins Engineering and offer the following comments:
1. The plans need to be signed by the design engineer.
2. On Sheet 4 of the plans, the sight lines for the intersection of Guadalupe Drive and
Colorado Road appear to originate at approximately 10' from the edge of the travel way.
The standards require that the sight lines originate at 14.5' from the edge of the travel
way. This needs to be corrected and the potential need for sight line easements will need
to be verified.
3. It is noted that the proposed waterlines within this development are located
approximately 2 to 3 feet from the edge of pavement. This will place the proposed
waterlines very near the tire path of vehicles traveling on these streets. The proposed
waterlines should be located outside of the paved surface. Waterlines and associated
appurtenances such as valves pose potential long term maintenance issues for VDOT.
4. On Sheet 6, it appears that the storm sewer between structures 24 and 26 may be shown
as radial pipe. All storm sewer within this project should be straight runs from structure
to structure.
5. It appears that the storm sewer could run from structure 32 to 30 rather than from 32 to
26. This would eliminate an unnecessary crossing of the Eastern Avenue Connector.
6. On sheet 8 it appears that the pavement designs are adequate based on an assumed CBR
value of 5. However, the pavement design table should be revised to accurately reflect
VDOT's Pavement Design Guide. The 2.15 Equivalency Value for BM -25 is only
applicable when there is a total depth of asphalt of 6" and that depth of asphalt is placed
directly on subgrade. If not placed directly on subgrade, the equivalency value for both
the SM -9.5 and the BM -25 is 2.25 if the total depth of asphalt is at least 4.5 "; otherwise
the equivalency value for the SM -9.5 and BM -25 layers should be 1.67. Please refer to
note 1 in the Footnotes for Appendix III of the Pavement Design Guide.
7. On sheet 13, several of the drop inlets are graphically shown located in the paved surface
of the turn lanes and tapers instead of the curb lines. It is understood that the Eastern
Connector is shown only for information purposes, but the inlets should be shown at the
correct locations if they are going to be shown.
8. On sheet 14, the invert out elevation of the 18" culvert under the Connector Road is
labeled incorrectly on the profile.
9. On sheet 15, a safety slab (SL -1) should be called for on structure 2.
10. On sheet 15, there should be at least a 0.10 foot drop across structure 16.
11. On sheet 16, there are several inverts in the calculations that do not correspond with the
inverts shown on the storm sewer profiles. The inverts of pipes 5, 7, 9, 11, and 14A do
not match the profile inverts. The most significant discrepancy is found in structure 14
(pipe 14A) where there is a difference of 0.90 feet in elevation of the invert, which results
in a 0.50% grade of the pipe in the profile and a 3.00 0.'0 grade of the pipe in the
calculations.
If additional information is needed concerning this project, please feel free to contact me.
Sincerely,
Z.

Scott,
RWSA has reviewed the Phase I Road Plans for the Westlake Hills Subdivision as prepared by Collins Engineering and
dated 5/20/2013 and has the following comments:
All Sheets:
1. Include all relevant items from the RWSA General Water and Sewer Notes (attached).
2. Label the RWSA sanitary sewer with ownership, size, and material (e.g. RWSA 15” VCP Sewer)
3. Include surveyed manhole inverts where applicable on plan sheets (e.g. CZI-MH-85).
4. In previous comments (see attached email), RWSA requested an additional 20’ of right-of-way along the existing
easement for the future upgrade of this sewer line. Please let me know if you’d like more information on this.
Sheet 5:
1. Include RWSA’s standard notes for a sewer connection:
All connections to RWSA manholes shall be watertight and made with a flexible rubber boot. All coring methods, the coring
contractor and all materials for construction shall be approved by RWSA in writing prior to construction. RWSA Engineering
Staff shall be present for all cores into the manholes. Bypass pumping may be required at the sole discretion of RWSA
staff. Grouting of the manhole bench or interior may be required, at the sole discretion of RWSA staff, for a smooth
transition of flow. Existing manholes shall be backfilled to original grade to the satisfaction of RWSA. Contact RWSA
Engineering a minimum of 3 business days in advance to schedule a core of a manhole.
2. RWSA would like to request an access easement from the property owner along the proposed 8” sewer.
Sheet 12:
1. Verify that the inverts listed for existing RWSA CZI-MH-85 are surveyed (as-built data is not always accurate).
2. Include ownership (RWSA) on CZI-MH-85.
3. Include standard sewer connection notes on this sheet (see above).

As mentioned previously, RWSA will require a flow acceptance for this project prior to approving site plans. Let me
know if you have any questions about my comments. We would like to make one final review once plans have been
revised, so please include us on your next submission.
Thanks a lot,

Division: Planning
Date: March 21, 2013
Rev1: June 6, 2013
Subject: SUB 2013– 00030 Westlake Hills – Phase I Road Plans
The County of Albemarle Planning Division will recommend approval of the Road Plans referenced above once the
following comments 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, which is to the Subdivision/Zoning Ordinances unless
otherwise specified.]
1. [Comment] This application was not submitted for subdivision plat review; comments provided are for Road
Plans only. However, for future reference, it does appear that the number of Phase I lots noted exceeds the
allowable density.
Rev1: Comment not fully addressed. This comment is applicable to any plat submittal. The density
calculation now appears to be approvable, however it seems a portion of the area added to Phase I
includes a change in the southern boundary of TMP 56-95B. This boundary line no longer matches
what is shown on County GIS and must be verified by plat.
2. [13.4.1] Environmental standards. Street trees are required to be shown on the road plans for this
development to meet the bonus factor approved with the preliminary plat that allowed for a smaller minimum lot
size and a smaller frontage requirement. It appears that many of the proposed tree locations have conflicts
with proposed utilities; these conflicts should be resolved before the plan is approved.
Rev1: Comment addressed.
3. [14-302(A)9 & Condition of Preliminary Approval] Building sites on proposed lots. The Board of
Supervisors approved a critical slope waiver request for this subdivision. An overlot grading plan must be
submitted as a condition of approval of this waiver.
Rev1: Comment not addressed. The grading plan shown on Sheet 6 does not meet requirements for an
overlot grading plan. Please coordinate with Engineering.
4. [14-302(B)3 & Condition of Preliminary Approval] Public areas, facilities or uses. Coordinate with the
Department of Parks and Recreation to establish the exact location of the greenway area and any other
facilities as noted in the Comprehensive Plan. Please refer to comments provided by Parks during preliminary
plat review.
Rev1: Comment in progress; coordination with Parks underway.
5. [Comment] The plant count provided for Thuja occidentalis appears to be incorrect; please verify and revise.
Rev1: Comment addressed.
6. [Comment] This subdivision is not subject to the tree canopy requirement. The adjoining property owners and
future residents of Westlake will benefit from as much tree canopy and existing tree preservation as possible,
but the requirement listed on the landscape plan isn’t applicable to this application.
Rev1: Comment addressed.

1. The fire hydrant symbols do not match the locations indicated by text on the plans. Fire Rescue will have no
objections to the plans if the symbols are moved to the locations indicated by text and an arrow on the plans.
2. The scale on Sheet 4 indicates 1"=30' which if this is the case the cul-de-sac is still not the appropriate size.
Sheet 5 indicates a scale of 1"=50' in which case the cul-de-sac is appropriately sized. Please indicate which scale
is corrected.
Once these changes are made/verified Fire Rescue will have no objections to the plans as submitted. SNM

Ellie,
I apologize for the delay in sending comments – we copy site plans from the ACSA, so there’s always a bit of a delay in
getting a copy for review. RWSA has reviewed the preliminary subdivision plat for Westlake Hills as prepared by Collins
Engineering and dated 3/26/2012 and has the following comments:
1. Due to the size of the proposed development, RWSA will need to approve sewage flows to determine that
adequate capacity is available when the development goes online. This request may be submitted during site
plan review.
2. The RWSA 15” sewer along the southern boundary of the development is slated for upgrade in the next 15-20
years. RWSA would like to request an additional 20’ of easement extending from the northern boundary of the
existing 30’ easement.
3. As development of this parcel may inhibit access to the existing RWSA easement, RWSA would like to discuss
the possibility of obtaining one or more access easements through the development.
4. As there appear to be several potential impacts to existing RWSA sewer lines within the project area (most
notably the connection to RWSA CZI-MH-137 and the locations and extents of SWM ponds and storm water
outfalls), RWSA will need to review site plans once they are available.
Please let me know if you have any questions.
Thank you,
Victoria

Michael,
Joel and I have reviewed the subject plan and have the following comments.
1.Vertical curves should have a minimum k value of 29 for crest curves and a minimum stopping sight distance of
250ft for 35mph roads.
2.Intersection sight distance of 390ft is need on the 35 mph connector road.
3.Raised rather than painted medians should be used on the connector road.
4.Trees should be planted at least 30ft from the end of the intersection radius.
5.If possible, lower the 12% grade on Guadalupe Drive to 10%.
Please let us know if you have any questions.
Thanks,

1. Please show entire parcel site with ACSA sewer easements for the east side of the property on sheet 3 (could
use a matchline and insert).
2. Please include a minimum 50' wide easement dedication for future proposed greenway area around property
(appears to be included for south and east sides but appears to need additional dedication for north side).
Please call with any questions - 296-5844

engineer.
C. Proposed Plan View Information
1. Please label apparent proposed SWM access easement shown on sheet 5.
2. Please re-route proposed drainage structure 4B to avoid conflict with potential driveway
for lot 36.
3. An overlot grading plan is required as a condition of critical slopes waiver approval.
Please provide a standalone overlot grading plan sheet for this proposed phase of construction as
part of the review of the road plans for this phase.
4. Please include stationing at 50’ minimum intervals on sheet 4 for each proposed public
road.
5. Please either remove references to Future Eastern Connector Road from this road plan set
or otherwise denote that all references to Future Eastern Connector Road (except intersection with
Colorado Road) are for information only and are not part of the proposed road construction for
West Lake Hills Phase I.
6. Recommend including striped crosswalks at Future Eastern Connector Road intersection
with Colorado Road and Westhall Drive due to projected traffic (will defer to VDOT).
Engineering Review Comments

Memorandum
To: Michael Koslow
From: Ellie Ray, PLA, Senior Planner
Division: Planning
Date: March 21, 2013
Subject: SUB 2013– 00030 Westlake Hills – Phase I Road Plans
The County of Albemarle Planning Division will recommend approval of the Road Plans referenced above once
the following comments 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, which is to the Subdivision/Zoning Ordinances unless
otherwise specified.]
1. [Comment] This application was not submitted for subdivision plat review; comments provided are for
Road Plans only. However, for future reference, it does appear that the number of Phase I lots noted
exceeds the allowable density.
2. [13.4.1] Environmental standards. Street trees are required to be shown on the road plans for this
development to meet the bonus factor approved with the preliminary plat that allowed for a smaller minimum
lot size and a smaller frontage requirement. It appears that many of the proposed tree locations have
conflicts with proposed utilities; these conflicts should be resolved before the plan is approved.
3. [14-302(A)9 & Condition of Preliminary Approval] Building sites on proposed lots. The Board of
Supervisors approved a critical slope waiver request for this subdivision. An overlot grading plan must be
submitted as a condition of approval of this waiver.
4. [14-302(B)3 & Condition of Preliminary Approval] Public areas, facilities or uses. Coordinate with the
Department of Parks and Recreation to establish the exact location of the greenway area and any other
facilities as noted in the Comprehensive Plan. Please refer to comments provided by Parks during
preliminary plat review.
5. [Comment] The plant count provided for Thuja occidentalis appears to be incorrect; please verify and
revise.
6. [Comment] This subdivision is not subject to the tree canopy requirement. The adjoining property owners
and future residents of Westlake will benefit from as much tree canopy and existing tree preservation as
possible, but the requirement listed on the landscape plan isn’t applicable to this application.
Please contact Ellie Ray at the Division of Current Development by using eray@albemarle.org or 434-296-5832
ext. 3432 for further information.
