Re: Proposed Long Term Acute Care Hospital (LTACH) — zoning determination
TM 59, Parcel 23B1)
Dear Mr. Hurt:
The purpose of this letter is to provide an official zoning determination regarding the
proposed long term acute care hospital (LTACH) on the above - referenced property. As
long as UVA owns or operates the building or use, the use is allowed by -right as a
public use" under Albemarle County Code § 18- 27.2.1(12). Although the University of
Virginia Medical Center is exempt from local zoning regulations under these
circumstances as an agency of the Commonwealth, Paragraph 1 of the Three Party
Agreement entered into by the University, the County and the City provides in this case
for submittal of a site plan.
This determination was made in consultation with the Albemarle County Attorney's
office and was based on information provided by you and others, including the
University of Virginia's General Counsel's Office. This decision is based on the fact that
the LTACH will be owned and operated by the University of Virginia Medical Center. By
letter from R. Edward Howell, CEO with University of Virginia Medical Center dated July
30, 2007, the Virginia Department of Health was informed of this fact and the fact that
HealthSouth will no longer be participating in this project. (Certificate of Public Need,
COPN #04053)
The subject property, TM 59, Parcel 23B1, is zoned LI, Light Industry. It is located on
Route 250, an Albemarle County Entrance Corridor. This property falls within Area C
under the Three Party Agreement entered into between the University of Virginia, the
County and the City. Paragraph 1 of the Agreement provides that the University will
voluntarily comply with the land use plans and regulations (as exemplified by those
listed in Exhibit 1) of either the City or the County regarding the use of real estate held
in Area C on the attached map." Exhibit 1 refers to the County's comprehensive plan,
the zoning ordinance, the subdivision ordinance, and the former erosion and sediment

Subject: Site Review Meeting Comments January 10` 2007 site review meeting
Dear Mr. Brooks:
Below are VDOT's comments on the Site Plans for the January 10 2007 Site Review Committee
Meeting:
SDP- 2007 -00150 Lane Bonner — Slope Waiver (Megan Yaniglos)
This plan was not included in the package.
SDP - 2007 -00154 ETC Building #2- Modular Laboratory Addition — Major (Patrick Lawrence)
Access to the proposed lab is through private road Discovery Lane and connects to public road
Lewis and Clark Drive. The increase in traffic expected from this use is minimal and the
access to the state road is adequate.
SDP -2007 -00155 Shadwell Market — Final (Summer Frederick)
Right in/out access needs to be located on the entrance at route 250 and the entrance at route
22 should have a full access.
What will the construction timeline he for the store? Construction on the road section is
expected in the spring of 2008 but has not been verified.
The truck turning diagram for fuel trucks shows the truck in opposing traffic lanes to enter the
site. This may cause problems if there are vehicles in the left turn lane of route 22 and left
turning movements from route 250 onto route 22 and a truck needs to get into the site.
SDP - 2007 -00157 UVA Long Term Acute Care Hospital — Preliminary (Gerald Gatobu)
The plan should add trip generations numbers for the site.
lbYEARS OP
TRANSPORTATION E}CCEUENCE
1 9 3 6 2 6 'e c+
There is an existing right turn lane at the proposed entrance to the site. Assuming the trip
estimates are relatively low, a right turn may be all that is necessary but the numbers should he
provided to determine is a left turn lane is warranted.
SDP - 2007 - 00158 Vest Property/ Verizon Tier II PWSF — Final (Gerald Gatobu)
The applicant has been in contact with VDOT on the multiple Verizon Tower projects
throughout the county. VDOT has indicated the need for adequate sight distances on all
of the sites but does not feel it to be necessary to upgrade these sites to the commercial
entrance standards in order to preserve the rural nature of many of the sites. hn the few
cases that the entrances do not meet the sight distance requirements, the applicant has
indicated they plan to propose other safety measures be taken to ensure safety. The
applicant is contacting VDOT on the individual sites and each site is being addressed for
safety.
SUB - 2007 - 00396 Clifton Lake, Phase I Subdivision — Preliminary (David Pennock)
Are there only two phases of this subdivision? If there are additional phases, they all
need to be shown on a sheet.
The curve on Shadwell Road that continues the road needs to be designed as a 25 mph
curve with a minimum 200 foot radius.
When full implementation of Chapter 527 regulations is in effect in June 2008, this plan
will fall under the threshold for a TIA.
The sight distance at the intersection of Shadwell Road with route 250 is limited to the
east and may not have adequate sight distance; the additional traffic causes safety
concerns without proper sight distance.
Please request the applicants provide a written description of revisions with re- submissions. If you
have any questions or comments, please contact me prior to sharing these comments with the
applicants.

2. Please provide traffic generation figures for the site entrances. [ 18- 32.5.6]
3. The critical slope waiver request has been received and will be reviewed separately. [ 18- 4.2.5.]
4. Please provide the SWM removal rate worksheets for the proposed BMP's. Please also show the
individual drainage areas to the BMP's. [17- 315B,C]
5. It appears that the 2:1 slopes in the back may present problems for installing the biofilter in that
location. It does not appear that there is sufficient area to install the proposed biofilter with a
graded access road that meets the slope requirements. [18- 32.5.6.k.]

Subject: Vest Property, Verizon Teir II PWSF: critical slope waiver request (SDP -2007 - 00158)
The critical slope waiver request has been reviewed. The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:
The critical slope disturbance on parcel 109 -4301 will be needed for the construction of the cell tower, fenced
enclosure, and access path. The disturbed critical slope is an area of nature hardwood trees sloping towards the
house at approximately 30 o.
Areas Acres
Total site 2.85 acres approximately
Critical slopes 2.42 1 85" o of site
Critical slopes disturbed 0.10 4 °'o of critical slopes
Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable alternative
locations:
The disturbance to construct the drheway to the fenced enclosure is exempt for the critical slope requirements.
4.2.6e] The combined area of the exempted critical slope disturbance (which has been included in the above
calculations) is 0.03 acres. This area is approximately 30''') of the critical slope disturbance.
Compliance with Zoning Ordinance 18 -4.2:
movement of soil and rock"
Construction of the building and other site features will most likely require a temporary increased Clow down
the critical slopes during a rain event. ;Movement of soil can be caught with an appropriate sediment trapping
measure before site runoffenters the existing storms titer system.
excessive stormwater runoff
The changing of site characteristics will increase stone runoff by an insignificant amount.
siltation''
Proper stabilization and maintenance will ensure long teen stability.
loss of aesthetic resource"
The critical slope disturbance is located 500ft from Nlaury's Lane, the nearest public space. The applicant has
performed a tree survey of the area and appears to have made abom e- average efforts to impact as few existing
trees and slopes as possible.
septic effluent"
This site will not require septic facilities.
Based on the review abo\ e, there are no engineering concerns with the proposed disturbance to critical slopes that
cannot be alleviated with the standard engineering and erosion control practices proposed by the applicant.

Subject: UVA Longterm Acute Care Hospital critical slope waiver request (SDP -2007- 00157)
The critical slope waiver request has been reviewed. The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:
The critical slope disturbance on parcels 59 -23B and 59-23B1 will be needed for the placement of the
building, surrounding travelways, and a loading dock.
The area of critical slopes located along the boundary line between the properties appears to be constructed
during the development of the Northridge parking lot (parcel 59 -23B). This slope is adequately
established and appears to be well - maintained.
Engineering is unsure whether the critical slopes located entirely on the Kirtley property (TMP 59 -23B1)
are man -made or natural. The trees on the slope appear to be mature and no scrub vegetation is present.
Though, due to its location, between two level building sites, it is possible the slope was created by the
development of the property decades ago.
TMP 59 -23B (The Northridge Property)
Areas Acres
Total site 5.03 acres approximately
Critical slopes 0.80 16% of site
Critical slopes disturbed 0.32 41% of critical slopes
TMP 59 -23B1 (The Kirtley Property)
Areas Acres
Total site 3.50 acres approximately
Critical slopes 0.63 18% of site
Critical slopes disturbed 0.30 48% of critical slopes
Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable
alternative locations:
A portion of this disturbance could be considered exempt. The area behind the building which is needed
to construct the biofilter could be exemptible. Although, it appears an alternative site layout or a smaller
footprint would eliminate the need for a SWM facility on the critical slope. [4.2.6c] The combined area of
the possible exempted critical slope disturbance (which has been included in the above calculations) is
0.078 acres. This area is approximately 13% of the critical slope disturbance.

Compliance with Zoning Ordinance 18 -4.2:
movement of soil and rock"
Construction of the building and other site features will most likely require a temporary increased flow
down the critical slopes during a rain event. Movement of soil can be caught with an appropriate
sediment trapping measure before site runoff enters the existing stormwater system.
excessive stormwater runoff'
Stonnwater runoff will be controlled on site by an underground detention facility and a biofilter. No
site runoff will run across critical slopes in the post development condition.
siltation"
Inspection and bonding by the County will ensure siltation control during construction. Proper
stabilization and maintenance will ensure long term stability.
loss of aesthetic resource"
The critical slope on the Northridge property (TMP 59 -23B) is visible from 250 and the Northridge
building. The critical slope on the Kirtley property is only visible from the on -site warehouse. On
both parcels, the critical slopes are covered by mature evergreen trees.
septic effluent"
This site is serviced by public sewer.
Based on the review above, there are no engineering concerns with the proposed disturbance to critical
slopes that cannot be alleviated with standard engineering and erosion control practices.
