RE: Belvedere Phase 5 — Road Plan - SUB-2019-00170
Dear David,
Please find attached the revised plans. The plans have been revised to address the comments
in accordance with the following:
County Planning — Brent Nelson
1. Revise Sheet 11 Landscape Plan to include a street tree linear foot street frontage
calculation. One large street tree is required for every 50 feet of street frontage.
Response: Street tree calculations have been provided for all streets that are part of this project.
2. Ensure that the street trees shown will be allowed in the proposed location and if not that
alternative locations are provided either within or outside of the right-of-way. If the trees
will be outside of the right-of-way landscaping easements will be required with ownership
and perpetual maintenance of the easements and landscaping put in place prior to the
final site plan approval.
Response: Landscaping easements have been added to all locations where street trees are not
within the right-of-way.
3. Proposed temporary fire road is blocked by proposed on -street parking located on the
proposed section of Fowler Street. Revise accordingly.
Response: Revisions have been made accordingly.
4. See staff comments for Initial Site Plan (SDP201900060, Belvedere Ph. 5):
Response: Acknowledged. The Initial Site Plan comments are addressed on the Road Plan and
the Initial/Final site plan.
a. Preserve all existing trees that are to remain. There are "Tree Save Areas" within
the site. If they are to remain include the following: Areas and other features
shown on landscape plan. The landscape plan shall show the trees to be
preserved, the limits of clearing, the location and type of protective fencing, grade
changes requiring tree wells or walls, and trenching or tunneling proposed
beyond the limits of clearing.
Response: The limits of clearing and grading have been added to plans to highlight the tree
save area.
914 Monticello Road, Charlottesville, VA 22902 172 South Pantops Drive, Charlottesville, VA 22901
b. Conservation checklist. The applicant shall sign a conservation checklist
approved by the agent to ensure that the specified trees will be protected during
construction. Except as otherwise expressly approved by the agent in a particular
case, the checklist shall conform to the specifications in the Virginia Erosion and
Sediment Control Handbook, pages III-393 through III-413.
Response: The Conservation Checklist has been added to the plan.
c. On the grading plan sheet label, the area of existing trees with the type of trees
(evergreen, deciduous, or a mix of both) and show areas where existing
vegetation will be removed.
Response: A label has been to indicate the tree save area. The limits of disturbance,
corresponding with the limits of disturbance shown on the VSMP, indicates the area to be
cleared. No disturbance is proposed in the critical slopes and protective fencing will be
proposed on the VSMP to delineate the critical slopes.
d. Ensure that all "Tree Save Areas" have trees in them and ensure areas which do
not have woods are not included in the areas or in the calculation for the areas.
Response: Acknowledged. The Tree Save Area is comprised of a mature deciduous forest.
e. Revise Sheet 11 Landscape Plan to include a street tree linear foot street
frontage calculation. One large street tree is required for every 50 feet of street
frontage.
Response: Street tree calculations have been provided for all streets that are part of this project.
f. [32.5.2(e), 32.5.2(p) & 32.7.91 Provide a full landscape plan that provides all
required landscaping, calculations and meets the landscaping requirements for
32.7.9. Ensure all calculations and graphics correctly represent the existing and
proposed plantings and planting areas.
Response: A full planting plan has been provided in this plan set. It includes the proposed
location of the trees and the calculations for street trees and canopy coverage.

master plan is received to determine if capacity exists for the connection to Belvedere
Phase 2B. As discussed during the preliminary design of this Phase, the ACSA would
like to see the sewer gravity towards the southeast towards the RWSA Rivanna
Interceptor. All sewer comments contained in this letter apply to the current design,
which may need to be altered to connect to the RWSA Rivanna Interceptor.
