Subject: SDP200900006, Comfort Suites Inn at Hollymead Town Center - Preliminary Site Plan
The preliminary site plan for Comfort Suites Inn at Hollymead Town Center, resubmitted on March 3,
2009, has been reviewed. Current Development Engineering can recommend approval of this site plan
once the following comments have been addressed:
Preliminary Site Plan Comments
1. The hatching on the legend (Cover Sheet) does not match the plans.
REV 1: Comment has been addressed.
2. Please label the existing easements with Deed Book & Page numbers.
REV 1: Comment has been addressed.
3. Please add sizes to the labels on the existing storm sewer pipes.
REV 1: Comment has been addressed.
4. Because of its close proximity (less than 300 ft) to the Timberwood Boulevard round -a -bout, a
left- turning movement into the existing curb cut on Conner Drive is not desirable. Please adjust
the Conner Drive median to prohibit vehicles from turning left into this development. This curb
cut may maintain right -in and right- and left -out movements.
REV 1: The connection to Conner Drive is an integral step for this development, and is shown in
the approved rezoning plan. The County will support full turning movements to and from Conner
Drive and the hotel site, provided that the connection is made.
The development proposes to utilize an existing curb cut on Timberwood Boulevard which
appears to operate as a right- and left -in and a right -out. There is potential for drivers exiting this
site to attempt to use this curb cut for a left turn onto Timberwood Boulevard. This poses a safety
concern and it is recommended that the entrance be designed to prohibit exiting vehicles from
attempting turning movements other than a right turn out onto Timberwood Boulevard.
REV 1: The County supports VDOT's recommendation that this median cut be closed. If full
closure is unattainable at this time, the Timberwood median must be extended to better align the
left turning movement with the entrance to this development, as shown on the approved rezoning
plan.
6. Existing lane markings on Route 29 south may need to be addressed at the location of the right -in,
right -out entrance on Route 29. The lane markings indicate a right- turn-only lane into this
entrance, however, the lane actually exists as a through lane. Increasing traffic and turning
movements at this entrance without addressing this contradiction creates a potential traffic hazard.
REV 1: This submittal has revised the right -turn arrows on Route 29 south to depict a through -
lane. VDOT and the County would prefer a dual - movement arrow depicting a through- and/or
right -turn -lane option. This can be shown on the Final Site Plan when it is submitted.
7. The three parking spaces proposed near the Route 29 entrance are a potential circulation hazard. It
is recommended that they are relocated.
REV 1: Comment has been addressed.
This site design proposes very little sidewalks and does not provide for walk- ability from many of
the parking spaces to the hotel or from the hotel to Target or Conner Drive. It is recommended
that sidewalk be added on one or both sides of the travelway from Conner Drive, around the
parking lots to the front entrance of the hotel. Also, connect sidewalks to the proposed walking
path. ( "Entrances and parking lots will be configured to be functional and inviting with walkways
conveniently tied to logical destinations." Page 14 of the Hollymead Towncenter Code of
Development for Area C)
REV]: Please provide walkable access from the proposed hotel to the Hollymead Towncenter
shopping area.
9. Grading between the proposed "curved" parking area and the walking path is steeper than the
maximum allowable 2 to 1 slope. [AC Design Manual 8.A.1]
REV 1: Comment has been addressed.
10. The grading between the existing Target water quality swale and the proposed parking appears to
create a swale behind the back of curb, this will concentrate flow and possibly cause erosion.
REV 1: Comment has been addressed.
11. Proposed grading creates a low point in the parking lot at the southwest corner of the hotel with no
inlet to collect drainage.
REV 1: Comment has been addressed.
12. The design of the travelway from the existing entrance onto Route 29 allows a large area of the
proposed parking to flow to the existing curb inlets, have these inlets been designed to handle this
flow?
REV 1: Comment has been addressed.
13. The proposed travelway from Conner Drive is steeper than the maximum allowable 10 %. [18-
4.12.17a]
REV 1: This travelway can be constructed to meet the slope requirements in the County
Ordinance. It is appropriate to make the connection to Connor Drive with this proposed
development to provide safe and convenient vehicular and pedestrian access for hotel patrons to
the Hollymead Towncenter shopping area.
14. In the location of the proposed travelway from Conner Drive, the vertical cover over an existing
sanitary sewer pipe is being reduced by up to 4 feet. Please verify that this pipe is deep enough for
the expected reduction in cover.
REV 1: Comment has been addressed.
15. Proposed grades in the parking area behind the Target exceed the maximum allowable 5 %. [18-
4.12.15c]
REV 1: Comment has been addressed.
16. An existing culvert shown in the parking area between the hotel and the vacant parcel to the
northwest remains on all plans with no notation regarding its removal.
REV 1: Comment has been addressed.
17. The proposed landscaping around the parking area adjacent to the existing rear entrance to Target
may cause sight distance problems for a vehicle taking a right turn from Target toward Route 29.
REV 1: Comment has been addressed.
18. The Hollymead Towncenter Code of Development for Area C (Page 21) states that water quality
swales, which will reduce the amount of untreated runoff entering the ponds, are proposed within
several development Blocks, including Block I. Although an existing water quality Swale is
located adjacent to this site, it is not clear that any of the developed flow will enter it.
REV]: The southern forebay to the pond will serve to collect larger particles of sediment and
pollutants, as well as trash and debris from the development. Even with bio filter plantings, it will
not appropriately function as a water quality feature. A water quality Swale (or a BMP of equal
treatment capability) to pre -treat stormwater before it enters the pond is required within Block I
per the Code of Development.
Final Site Plan comments
19. The Erosion & Sediment Control Plan submitted within this set will not be reviewed with the
preliminary site plan. For review of the E &SC Plan, please submit a Water Protection Ordinance
Application.
REV 1: Comment has been noted.
20. The Stormwater Management Calculations submitted with this set have only received a cursory
review with the preliminary site plan. For a full review of the Stormwater Management
calculations, please submit a Water Protection Ordinance Application.
REV 1: Comment has been noted.
21. This site proposes to utilize the existing C.W. Hurt Basin #1 for water quality and detention. This
plan also proposes modifications, including grading and extensive landscaping, to this pond.
Calculations will be required to validate that the requirements of water quality and quantity for this
site (in conjunction with other sites served by the pond) are being met. As -built conditions on the
existing pond should be utilized rather than topography proposed on previous design plans.
REV 1: Comment has been noted.
