Subject: SDP200900006, Comfort Suites Inn at Hollymead Town Center - Preliminary Site Plan
The preliminary site plan for Comfort Suites Inn at Hollymead Town Center, submitted on January 26,
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.
2. Please label the existing easements with Deed Book & Page numbers.
3. Please add sizes to the labels on the existing storm sewer pipes.
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.
5. 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.
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.
7. The three parking spaces proposed near the Route 29 entrance are a potential circulation hazard. It
is recommended that they are relocated.
8. 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)
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]
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.
11. Proposed grading creates a low point in the parking lot at the southwest corner of the hotel with no
inlet to collect drainage.
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?
13. The proposed travelway from Conner Drive is steeper than the maximum allowable 10 %. [18-
4.12.17a]
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.
15. Proposed grades in the parking area behind the Target exceed the maximum allowable 5 %. [18-
4.12.15c]
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.
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.
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.
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.
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.
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.
