Re: SUB -2015 -00065 Villas at Belvedere
Dear Ms. Ray
We have reviewed the Villas at Belvedere Final Site plan, dated of December 3, 2015, as
submitted by Collins Engineering, and offer the following comments:
1. The intersection sight line triangle should be labeled (i.e.: offset from the edge of travel
way and entrance centerline offset). The sight line triangle should be I4.5' from the edge
of the nearest automobile through lane.
2. A roadway typical section detail should be provided for the improvements made along
Belvedere Blvd (asphalt pathway, buffer width, cross - slopes, the location and width of
the proposed /existing ROW, as well as the street trees, should be graphically shown with
dimensions to the back of curb).
3. Diagonal curb ramps are not recommended for new construction. The Clarendon Alley
entrance should show CG -12's at the end of the entrance radii (One on each side, at the
tangent points on Clarendon Alley and one at the entrance tangent on Belvedere Blvd). A
new CG -12, on the Church of God side, will be installed, by others, at a later date. See
figure A -5 -15 of appendix A of the VDOT Road Design Manual for CG -12 selection
guidance. The existing CG- 1 Vmid-block crossing, approximately 250' east of Clarendon
Alley's entrance, should be identified on the plans.
4. CG -12 details should be included in the plan set.
5. PE -1 details should be included in the plan set.
6. The WP -2 details should be provided for tying in Clarendon Alley onto Belvedere Blvd.
7. We recommend paving the Belvedere BIvd/Clarendon Alley entrance to the end of the
radii. If pavers are used they shall be of a construction comparable to the pavement
section on Belvedere Blvd.
S. We do not recommend an emergency access connection onto Rio Road. We recommend
relocating the emergency access to Shepherds Ridge Road as previously submitted.
9. Multiple water service lines have been proposed across Belvedere Blvd. The crossings
should be jacked and bored or a single crossing should be made as previously submitted.
10. The 10 year water surface elevation should be provided for the existing DI -7 on Sheperds
Ridge Road. HGL computations should also be provided.
11. The maximum velocity for EC -2 is 4 ft/s. Based on the provided culvert computations the
outlet velocities exceed 4ft/s. The ditch lining should be upgraded to EC -3.
12. In the interest of assuring an adequate, convenient and safe access to public roads, we
recommend the grades along driveways to not exceed 10 %. Le.: Lots 13 and 14
13. A maintenance of traffic (MOT) plan should be provided.
14. The stormwater management plan and the erosion and sediment control plan should be
submitted for review. This may be submitted separately.
