Re: SUB - 2014 -00063 Fontana Phase 4C — Preliminary Plat
Dear Mr. Perez:
We have reviewed the preliminary plat for Fontana, Phase 4C dated 11/21.,-'08 with revisions
dated 11-1 &08, 4x28.11 0, 8.1-13:10, 1-411, &.10.1" 12, 1'2113, 4:7;14, 64! 14, and 8 '20.' l4 as
submitted by Terra Engineering and Land Solutions, PC and offer the following comments:
1. As previously noted and acknowledged, storm sewer calculations, open channel
calculations, storm sewer profiles, and pavement design calculations need to be provided
for review. Approval of this preliminary plat will by no means be an approval for road
and storm sewer /drainage channel design.
2. The roadway typical section should indicate whether there will be on- street parking on
one or both sides of the street. Also, if there will be on- street parking on one side only, it
should be indicated which side of the street will have on- street parking. Please note that
29' face of curb to face of curb at this location will meet VDOT standards for parking on
both sides of the street, however, this does not satisfy the minimum width requirement for
parking on both sides of the street to accommodate fire and rescue.
3. There should be a minimum of 90-- between the upstream and downstream storm sewer
pipes at each structure. It appears that there is less than 90= at structure between lots 21
and 22 on Brunello Court.
4. It appears that there is a conflict between the proposed entrance and the proposed storm
structure at lot 31 on Bruneilo Court.
5. Rather than connecting to the proposed storm sewer system, it appears that it would be
better to have a culvert under Belluno Lane at the connection with Via Florence Road.
The entrance angle to the culvert currently shown on the preliminary plat is more severe
than what is typically desirable.
6. It appears that the outlet from the proposed detention pond at the intersection of Belluno
Lane and Via Florence Road will create an obstruction in the roadside ditch along Via
Florence Road, potentially impacting the hydraulics of the roadside ditch. It would be
preferable to have the outlet stop short of the roadside ditch.
7. The typical section for the connection to Cascadia needs to be determined so that we can
verify that 40' of right -of -way is adequate. Please note that for a subdivision street that
will be brought into the secondary system for maintenance with less than 2,000 vehicles
per day, no on- street parking, curb and gutter, street trees and sidewalk on each side of
the street requires at a minimum 49' of right -of -way, i.e., 50' typically.
8. It appears that there should be standard CD -1's at approximately stations 10 +50, 10 +80,
12 +50 and 13 +00 of Brunello Court.
9. Adequacy of the proposed pavement design will need to be verified by pavement design
calculations. Please note that the Pavement Design Guide for Subdivision and Secondary
Roads in Virginia has been revised and the 2014 version should be used for pavement
design.
10. Additional comments may be provided during the road plan review process.
