RE: Response Letter #1 for SDP202000045 999 Rio Road Initial Site Plan Submittal
Dear Adam,
Thank you for your review of the initial site plan for 999 Rio Road. This letter contains responses to
County comments dated July 22, 2020.Our responses are as follows:
1. Please show mill and overlay on plans in accordance with WP-2, please add WP-2, detail to
plans. Please show mill and overlay to the adjacent travel lane.
RESPONSE: Comment received. Please see the updated site plan.
2. Work will require working in the center of the roadway, please provide MOT plan in accordance
with the 2019 revised Virginia Work Area Protection Manual.
RESPONSE: MOT plan has been provided with this submission.
3. Please refer to VDOT's Road Design Manual appendix F., pg. F-125, for design criteria on
Commercial Entrance along highways with curb and gutter. Please show geometry on both
proposed entrances, width needs to be a minimum of 30 ft.
RESPONSE: Comment received. Please see the revised site plan.
4. Please install CG-12 detectable warning surfaces at crosswalks.
RESPONSE: CG-12's are provided at crosswalks.
5. Please include turn lane warrant as appropriate.
RESPONSE: Comment received. We will provide the turn lane warrant analysis as a separate
submittal.
6. Please refer to appendix B(1)-pg.33, in VDOT's RDM for separation, between face of curb to the
edge of the shared use path shall be a minimum of 8 ft., in order to meet the minimum lateral
offset distance to install signs, for the roadway and the shared use path in accordance with the
MUTCD part 2 & 9. If signs are required on the outside of the shared use path due to horizontal
and vertical grade changes, then a minimum of 6.5 ft. of right of way from the edge of path shall
be provided otherwise, a minimum of 3 ft. right of way shall be provided. It appears the existing
shared use path along Belvedere Blvd. is outside of the existing right of way and will not be
maintained by VDOT.
RESPONSE: Per discussions with VDOT on January 20, 2021, the area outside of the shared use
path shall be 5'.
Width and clearance of shared use path, the recommended paved width for a two directional
shared use path is 10 ft. However in rare instances, a reduced width of 8 ft. can be adequate. This
reduced width should be used only where the following conditions prevail.
• Bicycle traffic is expected to be low, even on peak days or during peak hours.
• Pedestrian use of the facility is not expected to be more than occasional.
• There will be good horizontal and vertical alignment providing safe and frequent passing
opportunities.
• During normal maintenance activities the path will not be subject to maintenance vehicle
loading conditions that would cause pavement edge damage.
RESPONSE: The shared use path is reduced to 8' along Belvedere Boulevard as there is an
existing bike lane along Belvedere Boulevard. Cyclists would be more comfortable using the road
in this circumstance with a separate, designated lane and lower traffic levels on Belvedere
Boulevard, relative to Rio Road.
8. Please provide drainage calculations.
RESPONSE: Drainage calculations have been provided with this submission.
