County of Albemarle
Department of Community Development
Memorandum
To: Summer Frederick, Current Development Project Planner
From: Phil Custer, Current Development engineering review
Date: 2 June 2009
Subject: Martha Jefferson Hospital Major Amendment, Road Design (SDP- 2009 - 00039)
The major site plan amendment, received on 11 May 2009, has been reviewed. The engineering review for
current development cannot recommend approval to this application. The following comments are
provided.
1. This plan requires private road approval by the Planning Commission. The applicant
briefly mentioned their request for a private road in their application; however, the request
must be written as described in Section 14 -234 specifying which circumstance the waiver
request is being petitioned under (14- 233.A.1, 2, or 3). Engineering review will comment
on the waiver request in a separate memo once it is submitted. A sheet showing the
overall road network (at close to 200 scale) with all of the hospital entrances designated
may be helpful for the Planning Commissions review of the waiver.
2. In the development areas, all new private or public roads require curb and gutter. [ 14-
410.H] Please also include in the private road waiver request justification for a curb and
gutter waiver as outlined in section 14- 225.1. Any other road standard waiver should also
be requested at this time. Engineering review will comment on the waiver request in a
separate memo once it is submitted.
3. If this road plan is approved, it will replace the existing approved road plan for this section
of Willis Drive. When the time comes for the roadway to be upgraded to full buildout, a
new road plan will need to be reviewed and approved by VDOT and the County. Please
also remove references to ultimate design in both the plan and profile.
4. Please provide the rural road cross - section detail that will be utilized roughly from Sta.
204 +60 to 216 +40.
5. Please provide an ADT estimate for each segment of Willis Drive up until the time of
conversion to the curb and gutter section. The pavement, vertical alignment, and
horizontal alignment should be designed for the maximum ADT. The existing pavement
along Willis Drive will need to be upgraded to the strength needed to carry the increased
traffic.
6. The minor amendment approved for the 1575 State Farm parcel will expire on July 1St
2014. If the site is not constructed by that date, the site plan amendment will expire and a
new amendment will be required when Willis Road is widened to its full section.
7. Please clearly delineate where the public ROW line will terminate.
8. In the drainage profiles, please label all DI -7 or DI -5 structures proposed at this time as
such and include only one rim elevation for each structure. When the full buildout road
plan is approved, the conversion of the grate inlets to curb inlets will be reviewed and
approved at that time.
9. Contours do not appear to be continuous. Please check all lines to make sure the grading
is shown correctly.
10. All curblines and other improvements on the OCC site should match the approved minor
amendment (SDP- 2008 - 00089).

11. Because the 50ft public ROW will not be dedicated in this phase, please show all drainage
easements to their full width. The width of the drainage easement should be computed
based on the equation found in the design manual (minimum 20ft).
12. Please provide channel calculations for the roadside ditches.
13. Safety slabs are required in all structures deeper than 12ft.
14. Please show all cross drains and storm sewer crossings in the road profiles.
