The facility primarily includes a biofilter. The biofilter designed to control excess runoff of post development conditions to predevelopment peak runoff rates. Also, the biofilter is designed to treat 0.5 inch of first flush from the additional impervious areas of proposed development. The Modified Rational Method (recommended by both the state of Virginia and Albemarle County) is used for hydrologic analysis. PROJECT DESCRIPTION The SIEG Maintenance property is located in Albemarle County. The property is located on tax maps/ parcels TMP 59 -23D, TMP 59 -23F and TMP 59 -23C1. The proposed development is an extension of the existing parking lot. The existing parking lot has 54 spaces and the proposed parking lot will have 96 parking spaces. METHODOLOGY Pre - Development Hydrology In existing condition, the property consists of approx. 3 acre of drainage area and currently built with a Warehouse and a parking lot. The majority of the site has impervious cover and has slope less than 10 percent. The 2 -yr and 10 -yr predevelopment runoff from the site are approx. 8.98 cfs and 11.55 cfs respectively. Post - Development Hydrology The post - development hydrology is the same as pre - development hydrology. Approx. all the runoff from the site is going into the proposed biofilter. The 2 -yr and 10 -yr discharge from the biofilter are 7.04 cfs and 8.82 cfs respectively. In biofilter, the storage volume displaced by any plantings above the filter bed is ignored. Also, any storage in the bio filter media void space is not taken into account for available storage space. The biofilter is sized to treat 0.5 inch of first flush. The required water quality volume is approx. 583 cf and the biofilter is sized to treat approx. 637 cf. SUMMARY The proposed biofilter is designed to adequately treat 0.5 inch of first flush from the proposed impervious area and to control excess runoff from the postdevelopment condition. The facility can treat approx. 637 cf of runoff compare to the required 0.5 inch of first flush treatment volume (approx. 583 cf).

Figure 1 illustrates the site location_ The proposed development is planned to include a new, 62,000 square foot (sf) building consisting of a 54,000 sf long term acute care (LTAC) facility (40 adult beds and 10 pediatric beds) and 8,000 sf of radiology support services. In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by the University of Virginia (UVA) and will be maintained with similar uses by the UVA Health Services Foundation. Parking to support the proposed development cannot be provided solely on the existing Northridge site. In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended: Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off -site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off -site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minimally increase the volume of traffic on Ivy Road and at study area intersections. To mitigate potential operational issues and provide for acceptable levels of service throughout the study area, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two -way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Page 1 Northndge Development ]anuan 25, 2008 Ivy Road/Ser«ce Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and difficult to discern) Page 2 Northridge Development 2.0 Introduction January 25 2008 The Northridge Development is proposed to be located on Ivy Road adjacent to the existing Northridge building in Albemarle County, Virginia. In general, the site is bounded by a Volvo dealership to the west, a Fleet Operations building to the east, Ivy Road to the south, and the CSX Railroad to the north. As shown in Figure 1, Ivy Road runs in an east /west direction and connects to the U.S. Route 29/250 Bypass to the east of the site. The proposed development is planned to include an approximately 62,000 square foot (sf) building to contain the following: Long term acute care facility - 54,000 sf (40 adult beds and 10 pediatric beds) Radiology support services -8,000 sf The anticipated construction and occupancy timeline for the proposed building is approximately three years -2010. The proposed building is planned to occupy an undeveloped portion of the existing Northridge property, as well as part of the existing Kirtley property, which was previously occupied by TJW Distribution Center and the Lee Tennis Products office building. Both the warehouse and the office building have been acquired by UVA and will be maintained with similar uses by the UVA Health Services Foundation. Kimley -Horn and Associates, Inc. (KHA) has been retained to perform a traffic impact analysis for the proposed development. This report has been prepared for submittal to Albemarle County to evaluate existing conditions as well as future traffic conditions that include the proposed project.

In the vicinity of the proposed development, there is a medical office building, a warehouse, a small office building, and a Volvo dealership. 3.3 Existing Conditions Ivy Road (U.S. Route 250) is the primary thoroughfare within the study area. U.S. Route 250 runs parallel to Interstate 64 between Richmond and Staunton, from which point it continues northwest into West Virginia, eventually connecting to Interstate 79. Regionally, Ivy Road provides access to the U.S. Route 29/250 Bypass and to the University of Virginia. Within the study area, Ivy Road is a three -lane roadway with a two -way left -turn lane (TWLTL). Several signalized intersections are located along Ivy Road, as well as numerous unsignalized driveways. The posted speed limit on Ivy Road is 45 miles per hour. Traffic counts estimated by the Virginia Department of Transportation (VDOT) indicate that in 2006, Ivy Road was carrying approximately 14,000 vehicles per day (vpd) in the vicinity of the proposed development. Traffic counts were conducted by Kimley -Horn and Associates, Inc. in November 2006 on Ivy Road, and these counts indicated that the average weekday daily traffic (ADT) volume was approximately 17,800 vpd Existing roadway laneage for study area roadways and intersections is illustrated in Figure 2.

The parking lot at the existing Northridge building will be modified to accommodate the main entrance and drop -off for the proposed Northridge development. Likewise, the existing parking lot adjacent to the office building will be modified to accommodate a drop -off for patient transfer vehicles. Parking generation potential for the existing and proposed land uses was calculated using parking generation rates published in Parking Generation (Institute of Transportation Engineers [ITE], 3rd Edition, 2004) to determine if the existing parking areas will be adequate to support the addition of the proposed Northridge development. 4.1 Existing Northridge Building Parldng Occupancy ITE Code 720 (Medical - Dental Office Building) was used to approximate the parking generation potential of the existing 58,770 sf Northridge building. In addition, Kimley -Horn verified existing parking inventory and collected actual occupancy data on Wednesday, December 5, 2007 at 10:00 AM, 12:00 PM, 2:00 PM, and 4:00 PM. Staff and visitor parking were counted separately; however, they are combined for analysis purposes. Parking demand generated by ITE was supplemented with actual occupancy counts, and the surrounding hours were adjusted accordingly. The peak occupancy count was nearly identical to the peak parking demand generated by ITE; however, actual occupancy later in the afternoon was less than generated by ITE. Table 1 below summarizes the parking demand at the Northridge building by the hour and indicates the number of remaining (unoccupied) parking spaces. Any facility that is at least 90% occupied is considered "full" by industry standards to account for circulation, turnover, and access. The number of available spaces has accordingly been reduced to account for 90% occupancy rather than 100% in order to maintain some surplus for circulation and turnover.

With the proposed modifications, 253 total parking spaces will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 253 spaces. Table 1 indicates that only 22 parking spaces are available during the peak demand period (10:00 AM to 12:00 PM). 4.2 Proposed Northridge Development Parldng Generation Parking Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. ITE Code 620 (Nursing Home) was used for the LTAC due to low peak hour and daily parking/traffic generation observed at existing LTAC facilities. Parking generation for the LTAC based on gross floor area (54,000 sf) results in a demand significantly higher than if generated based on beds (50 beds). To provide a worse case scenario, parking demand was generated based on gross floor area. ITE Code 720 (Medical- Dental Office Building) was used to generate parking demand for the 8,000 sf Radiology Support Services. Table 2 below summarizes the parking generation potential of the proposed Northridge development by the hour.

Although the peak parking period occurs later than at the existing Northridge facility, the parking demand was compared to available spaces at the existing facility to determine whether additional parking spaces will be required. Table 3 summarizes the total parking demand and availability.

In order to accommodate the additional parking Page 10 Northndge Development January 25, 2008 demand and maintain a 10% surplus to account for circulation and turnover, an additional 41 parking spaces are needed on the Northridge site. Using a parking rate of 0.9 vehicles per employee (ITE Code 620), this results in the need to relocate approximately 46 employees to off - site or satellite parking. The UVA Health Services Foundation has indicated that they will commit to relocating at least 46 employees by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Shuttle service is currently provided at the Northridge building. If the 46 employees cannot be accommodated at a nearby property, satellite parking with shuttle service could be utilized by either existing Northridge employees or future LTAC employees because parking will be shared between the two facilities. It should be noted that the potential parking demand for the proposed Northridge development was generated on the conservatively high side. Actual parking conditions should be monitored periodically. In addition, it is anticipated that some parking spaces will be available on the existing Kirtley property near the warehouse building. Existing parking occupancy data could not be collected at the existing office and warehouse buildings on the Kirtley property as they are both currently vacant. However, parking generation potential was determined based on ITE rates. ITE Code 710 (General Office) was used to generate parking demand for the 4,300 sf office building. ITE Code 150 (Warehousing) was used to generate parking demand for the 23,000 sf warehouse building. Table 4 below summarizes the hourly parking generation potential of these facilities. Table 4— Hourly Parking Generation Potential of Existing Kirtley Property Hour Beginning Office Parking Demand Warehouse Parking Demand Total Parking Demand Unoccupied Parking Spaces Actual Parking Spaces Available (90 %) Page 11 Northridge Development January 25, 2008 A total of 59 parking spaces (21 office and 38 warehouse) are currently provided on the Kirtley property. With the proposed modifications, 48 total parking spaces (10 office and 38 warehouse) will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 48 spaces. Table 4 indicates that at least 21 parking spaces will be available on the Kirtley property, even during peak times. The UVA Health Services Foundation may choose to allow LTAC employees to park near the Kirtley warehouse to reduce the number of employees that must be accommodated at an off -site or satellite facility. Page 12 Northridge Development 5.o Traffic Generation January 25, 2008 Traffic generation potential for the proposed development was determined using traffic generation rates published in Trip Generation (Institute of Transportation Engineers [ITE], 7` Edition, 2003). 5.1 Proposed Development Trip Generation Table 5 summarizes the estimated traffic generation potential for the proposed development under the future build -out (2010) scenario. Trip Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. ITE Code 620 (Nursing Home) was used for the LTAC due to low peak hour and daily traffic generation observed at existing LTAC facilities. ITE Code 720 (Medical- Dental Office Building) was used to approximate the trip generation potential of the Radiology Support Services. Table 5— Proposed Development Trip Generation —Full Build -out ITE AM Code Description Size Unit Daily In 620 Long Term Acute Care 54,000 sf 329 *14 Peak Hour Out 7 PM Total In 21 11 Peak Hour Out 12 Total 23 720 Radiology Support Services 8,000 sf 289 16 4 20 8 22 30 Total New Site Generated Trips 618 30 11 41 19 34 53 Note: A directional distribution of 69% entering and 31% exiting was assumed based on AM Peak Hour of the Generator data using "beds" as an independent variable. Table 5 indicates the proposed development having the potential to generate a total of 618 new daily trips, 41 of those occurring in the AM peak hour and 53 occurring in the PM peak hour. Although 46 employees will be parked at an off -site location, it is unclear at this time whether they can be accommodated at a nearby property or if they will utilize satellite parking with shuttle service. For the purposes of the traffic analysis, in order to analyze a worse case scenario, no trip reductions were applied to the estimated trip generation potential to account for employees that may be shuttled from satellite parking locations. It should be noted that while assigning the full trip generation potential to the study area intersections will appropriately account for additional traffic on Ivy Road, it will overstate the turning movements at the site driveways. Page 13 Northndge Development January 25, 3008 In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by UVA and will be maintained with similar uses by the UVA Health Services Foundation. Because these buildings were occupied by their former tenants at the time of the data collection (November 2006), trips associated with these uses are included in the existing traffic counts and will not be generated as new site trips. Page 14 Northridge Development 6.o Traffic Distribution January 25, 2008 The directional distribution and assignment of trips generated by a development is typically based on a review of existing roadway volumes, an understanding of travel patterns within the study area, and from assumptions of anticipated shifts in travel patterns due to the construction of the development. In the case of the proposed development, directional distribution was determined from the existing Northridge building, a similar land use. The following distribution applies to the 2010 development condition: 85% to /from the east on Ivy Road 15% to /from the west on Ivy Road Site traffic distribution is illustrated in Figure 3.

Site Access and Traffic Assignment Ivy Road (U.S. Route 250) will be the primary corridor providing access to the proposed development. The main entrance to the proposed building will be located on the east side of the building at the parking (ground) level. As a result, all visitors, patients, and staff will utilize the Northridge Main Entrance, which will also continue to serve the existing Northridge building. An ambulance /transfer vehicle drop -off will be provided on the west side of the building. Due to the elevation change over the two adjacent properties, this entrance will provide direct access to the second floor Long Term Acute Care (LTAC) facility. The existing Service Entrance will therefore provide access to a very small portion of proposed LTAC traffic and will continue to provide access to the existing warehouse and two -story office buildings. It is assumed that approximately 5% of LTAC traffic will utilize the Service Entrance. All other proposed Northridge traffic will utilize the Northridge Main Entrance. Page 17 Northridge Development lanuary 25, 2008 8.o Projected Traffic Volumes 8.1 Historic Traffic Growth Historic traffic growth is the increase in traffic volumes due to usage increases and non - specific growth throughout an area. One method of determining reasonable growth rates for an area is to research past traffic counts for a roadway or intersection. The following are traffic counts from the VDOT count program: Iiy Road 2006- 14,000 vehicles per day (vpd) 2005 - 15,000 vpd 2004 - 14,000 vpd 2003 - 13,000 vpd 2002 - 14,000 vpd 2001 - 12,000 vpd Based on the VDOT data, a background growth rate of 5.5% was used in this study. No other major developments that need to be considered in the analysis are anticipated in the vicinity of the proposed development. Any redevelopment or smaller development in the site's vicinity is assumed to be accounted for by the background growth factor. 8.2 Total Traffic To obtain total 2010 build -out traffic volumes, existing (November 2006) traffic volumes were incrementally increased using the aforementioned background growth rate. Existing turning movement volumes were increased by 17.4 percent to reflect future background traffic growth for three years (to 2010). Once background traffic volumes were established, traffic associated with the proposed development was added to develop 2010 total (build -out) traffic volumes. The following figures illustrate future turning movement volumes: Figure 4-2010 AM peak hour Figure 5 --2010 PM peak hour Page 18 North Not to Scale UC Cw U C O C Lu a U J- 0 cn z 0 1 26 (1) [27] L_ 115 (24) [139] 4 — 469 (2) [471] f— 475 (1) [476] 7 [21] (5) 16 Ivy Road 1155] (5) 1150 00 [1208] (1) 1207 —0 Legend 0 - Unsignalized Intersection XX (XX) [XX] - Background (Site) [Total] Peak Hour Volumes I F1 FIGURENorthridgeDevelopmentFuture (2010) AM Peak Kimley -Horn Albemarle County, Virginia Hour Traffic Volumes 4andAssociates, Inc.

Intersection turning movement counts were used with information about the number of lanes and traffic control to determine existing and future levels of service. Level of service (LOS) describes traffic conditions the amount of traffic congestion —at an intersection or on a roadway. LOS ranges from A to F —A indicating a condition of little or no congestion and F a condition with severe congestion, unstable traffic flow, and stop- and -go conditions. For intersections, LOS is based on the average delay experienced by all traffic using the intersection during the busiest peak) 15- minute period. LOS A through D are generally considered acceptable. Each of the aforementioned scenarios was analyzed during the weekday AM and PM peak hours. The results are presented in the following summaries, and supporting calculations are presented in the Appendix. Page 21 Northndge Development January 25, 2008 9.1 Ivy Road /Northridge Main Entrance This unsignalized intersection currently provides the following laneage: Ivy Road (eastbound)---one exclusive through lane and one exclusive left -turn lane Ivy Road (westbound) --one exclusive through lane and one exclusive right -turn lane Northridge Main Entrance (southbound) --one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS D and F during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is expected to worsen to LOS E during the AM peak hour. Under the same conditions, delay is anticipated to increase significantly during the PM peak hour such that the movement continues to operate at LOS F. Table 6 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table 6 —Ivy Road/Northridge Main Entrance Intersection Unsignalized LOS Under future traffic conditions, operations on Ivy Road will not change appreciably. Levels of service for all movements except for the southbound (site driveway) left -turn movement will not change under future traffic conditions. To improve operations for the southbound (site driveway) approach would require that a traffic signal be installed. Traffic signal warrant analyses were performed at this location referencing the Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition to evaluate the need for traffic signalization under existing (2006) conditions. According to the MUTCD, a traffic control signal should not be installed unless one or more of the signal warrants in the MUTCD are met. However, "the satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal." The three main warrants are as follows: Page 22 Northndge Development January 25, 2008 Warrant 1 (Eight -Hour Vehicular Volume} —is satisfied if ONE of the following conditions exists for any eight hours of a day: o Condition A (Minimum Vehicular Volume) — volumes do not meet or exceed the necessary thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. o Condition B (Interruption of Continuous Traffic)— volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. o Combination of Condition A and B (Combination of Condition A and B}— volumes do not meet or exceed the necessary combination of thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. Warrant 2 (Four -Hour Vehicular Volume} — volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for four hours. Warrant 3 (Peak Hour Volume )--volumes meet or exceed the necessary thresholds for this warrant during four hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for one hour. These warrants are based on mainline and side street traffic volumes, number of travel lanes (one per approach), and mainline travel speed (45 mph). As is common practice, right -turn volumes were excluded from the projected side street volumes because an exclusive right -turn lane is provided. Detailed warrant analyses are included in the Appendix. Based on existing ADT volumes and four hours of turning movement volumes, analyses indicated that the intersection of Ivy Road and the Northridge Main Entrance currently warrants a traffic signal. Although a full 12 -hour turning movement count was not performed at this time, signal warrants were evaluated using reasonable estimates of the hourly distribution of outbound left - turn volumes based on ITE daily trip generation. Existing peak hour inbound and outbound trips very closely mirror estimated ITE trip generation for the existing Northridge building. With this signal and based on projected traffic volumes, vehicle queues in eastbound and westbound (Ivy Road) through lanes will not extend through adjacent intersections /driveways and create blockages. Table 7 summarizes signalized level of service at this intersection for future scenarios. Page 23 Northridge Development January 25, 20018 Table 7 —Ivy Road/Northridge Main Entrance Intersection Signalized LOS To provide acceptable LOS at this intersection as indicated in Table 7, the following are recommended: Maintain existing laneage Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate soutbbound movements from the Northridge Main Entrance Figure 6 shows recommended laneage and traffic control at this intersection. Detailed level of service calculations are provided in the Appendix. Page 24 Northndge Development January 25, 2008 9.2 Ivy Road /Service Entrance This unsignalized intersection currently provides the following laneage: Ivy Road (eastbound} --one exclusive through lane and one exclusive left -turn lane Ivy Road (westboundy- -one exclusive through lane and one exclusive right -turn lane Service Entrance (southbound)—one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS C and D during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is anticipated to worsen to LOS D during the AM peak hour and maintain LOS D during the PM peak hour. Operations on Ivy Road, including the eastbound left -turn movement into the site, will be negligibly impacted by the development. Table 8 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table 8 —Ivy Road/Service Entrance Intersection Unsignalized LOS No improvements are recommended at this intersection. Detailed level of service calculations are provided in the Appendix. Page 25 Northridge Development January 25, 2008 mo Conclusions and Recommendations Parking to support the proposed development cannot be provided solely on the existing Northridge site. In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended: Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off -site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off -site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minimally increase traffic volumes on Ivy Road and at study area intersections. Recommended improvements will mitigate development traffic impacts. To maintain acceptable traffic operations at study intersections, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two -way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Ivy Road/Ser-7ce Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and difficult to discern) Page 26 PPP" MF1 FIGURE1111116- M Northridge Development Recommended Kimley -Horn Albemarle County, Virginia Roadway Laneage 6 and Associates, Inc.

Figure 1 illustrates the site location. The proposed development is planned to include a new, 62,000 square foot (sf) building consisting of a 54,000 sf long term acute care (LTAC) facility (40 adult beds and 10 pediatric beds) and 8,000 sf of radiology support services. In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by the University of Virginia (UVA) and will be maintained with similar uses by the UVA Health Services Foundation. Parking to support the proposed development cannot be provided solely on the existing Northridge site. In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended: Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off -site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off -site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minimally increase the volume of traffic on Ivy Road and at study area intersections. To mitigate potential operational issues and provide for acceptable levels of service throughout the study area, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two -way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Page 1 Northndge Development 1anuan• 25, 2008 Ivy Road/Service Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and difficult to discern) Page 2 Northridge Development 2.0 Introduction Jarmary 25 2008 The Northridge Development is proposed to be located on Ivy Road adjacent to the existing Northridge building in Albemarle County, Virginia. In general, the site is bounded by a Volvo dealership to the west, a Fleet Operations building to the east, Ivy Road to the south, and the CSX Railroad to the north. As shown in Figure 1, Ivy Road runs in an east /west direction and connects to the U.S. Route 29/250 Bypass to the east of the site. The proposed development is planned to include an approximately 62,000 square foot (sf) building to contain the following: Long term acute care facility- 54,000 sf (40 adult beds and 10 pediatric beds) Radiology support services -8,000 sf The anticipated construction and occupancy timeline for the proposed building is approximately three years -2010. The proposed building is planned to occupy an undeveloped portion of the existing Northridge property, as well as part of the existing Kirtley property, which was previously occupied by TJMF Distribution Center and the Lee Tennis Products office building. Both the warehouse and the office building have been acquired by UVA and will be maintained with similar uses by the UVA Health Services Foundation. Kimley -Horn and Associates, Inc.

In the vicinity of the proposed development, there is a medical office building, a warehouse, a small office building, and a Volvo dealership. 3.3 Existing Conditions Ivy Road (U.S. Route 250) is the primary thoroughfare within the study area. U.S. Route 250 runs parallel to Interstate 64 between Richmond and Staunton, from which point it continues northwest into West Virginia, eventually connecting to Interstate 79. Regionally, Ivy Road provides access to the U.S. Route 29/250 Bypass and to the University of Virginia. Within the study area, Ivy Road is a three -lane roadway with a two -way left -turn lane (TWLTL). Several signalized intersections are located along Ivy Road, as well as numerous unsignalized driveways. The posted speed limit on Ivy Road is 45 miles per hour. Traffic counts estimated by the Virginia Department of Transportation (VDOT) indicate that in 2006, Ivy Road was carrying approximately 14,000 vehicles per day (vpd) in the vicinity of the proposed development. Traffic counts were conducted by Kimley -Horn and Associates, Inc. in November 2006 on Ivy Road, and these counts indicated that the average weekday daily traffic (ADT) volume was approximately 17,800 vpd. Existing roadway laneage for study area roadways and intersections is illustrated in Figure 2. Page 5 Northridge Development 3.4 Existing Traffic January 25, puns AM and PM peak hour weekday turning movement counts were performed by Peggy Malone and Associates, Inc. at the following study intersections: Ivy Road/Northridge Main Entrance — November 15, 2006 Ivy Road/Service Entrance — November 15, 2006 In addition to turning movement counts, an ADT volume count was conducted on Ivy Road on November 14 and 15, 2006. This count indicated an ADT volume of 17,800 vpd. Study peak hour turning movement volumes at intersections are shown in Figure 2.

Northridge Development 4.0 Parking Generation January 25, 2008 No new parking is planned to be provided exclusively for the proposed Northridge development. The parking lot at the existing Northridge building will be modified to accommodate the main entrance and drop -off for the proposed Northridge development. Likewise, the existing parking lot adjacent to the office building will be modified to accommodate a drop -off for patient transfer vehicles. Parking generation potential for the existing and proposed land uses was calculated using parking generation rates published in Parking Generation (Institute of Transportation Engineers [ITE], 3rd Edition, 2004) to determine if the existing parking areas will be adequate to support the addition of the proposed Northridge development. 4A Existing Northridge Building Parldng Occupancy ITE Code 720 (Medical - Dental Office Building) was used to approximate the parking generation potential of the existing 58,770 sf Northridge building. In addition, K.imley -Hom verified existing parking inventory and collected actual occupancy data on Wednesday, December 5, 2007 at 10:00 AM, 12:00 PM, 2:00 PM, and 4:00 PM. Staff and visitor parking were counted separately; however, they are combined for analysis purposes. Parking demand generated by ITE was supplemented with actual occupancy counts, and the surrounding hours were adjusted accordingly. The peak occupancy count was nearly identical to the peak parking demand generated by ITE; however, actual occupancy later in the afternoon was less than generated by ITE. Table 1 below summarizes the parking demand at the Northridge building by the hour and indicates the number of remaining (unoccupied) parking spaces. Any facility that is at least 90% occupied is considered "full' by industry standards to account for circulation, turnover, and access. The number of available spaces has accordingly been reduced to account for 90% occupancy rather than 100% in order to maintain some surplus for circulation and turnover. Page 8 Northndge Development Table 1— Hourly Parking Demand at Existing Northridge Building January 25, 2008 Hour Beginning 6:00 AM Parking Demand 20 Unoccupied Parking Spaces 233 Actual Parking S Available (90%) 208 7:00 AM 32 221 196 8:00 AM 102 151 126 9:00 AM 175 78 53 10:00 AM 206 47 22 11:00 AM 206 47 22 12:00 PM 160 93 68 1:00 PM 164 89 64 2:00 PM 177 76 51 3:00 PM 163 90 65 4:00 PM 132 121 96 5:00 PM 100 153 128 6:00 PM 75 178 153 A total of 254 parking spaces (88 staff and 166 visitor) are currently provided at the Northridge site. With the proposed modifications, 253 total parking spaces will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 253 spaces. Table 1 indicates that only 22 parking spaces are available during the peak demand period (10:00 AM to 12:00 PM). 4.2 Proposed Northridge Development Parking Generation Parking Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. E Code 6 02 (Nursmg Iome was used for the LTAC due to low peak hour and daily parking/traffic generation observed at existing LTAC facilities. Parking generation for the LTAC based on gross floor area (54,000 sf) results in a demand significantly higher than if generated based on beds (50 beds). To provide a worse case scenario, parking demand was generated based on gross floor area. ITE Code 720 (Medical - Dental Office Building) was used to generate parking demand for the 8,000 sf Radiology Support Services. Table 2 below summarizes the parking generation potential of the proposed Northridge development by the hour.

Although the peak parking period occurs later than at the existing Northridge facility, the parking demand was compared to available spaces at the existing facility to determine whether additional parking spaces will be required. Table 3 summarizes the total parking demand and availability. Table 3— Hourly Parking Space Allocation Hour Beginning 6:00 AM Parkin Existing Northridge D• 20 Existing Parking Spaces Available 9i 208 Proposed Northridge Development Parking 23 Net Parking Spaces 185 7:00 AM 32 196 31 165 8:00 AM 102 126 45 82 9:00 AM 175 53 59 6 10:00 AM 206 22 62 40 11:00 AM 206 22 63 41 12:00 PM 160 68 59 9 1:00 PM 164 64 58 6 2:00 PM 177 51 82 31 3:00 PM 163 65 85 20 4:00 PM 132 96 57 39 5:00 PM 100 128 35 93 6:00 PM 75 153 23 130 As indicated in Table 3, there is not sufficient parking supply at the existing Northridge building to accommodate the parking demand from the proposed Northridge development during the peak parking period from 11:00 AM to 12:00 PM. In order to accommodate the additional parking Page 10 Northridge Development January 25, 2008 demand and maintain a 10% surplus to account for circulation and turnover, an additional 41 parking spaces are needed on the Northridge site. Using a parking rate of 0.9 vehicles per employee (ITE Code 620), this results in the need to relocate approximately 46 employees to off - site or satellite parking. The UVA Health Services Foundation has indicated that they will commit to relocating at least 46 employees by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Shuttle service is currently provided at the Northridge building. If the 46 employees cannot be accommodated at a nearby property, satellite parking with shuttle service could be utilized by either existing Northridge employees or future LTAC employees because parking will be shared between the two facilities. It should be noted that the potential parking demand for the proposed Northridge development was generated on the conservatively high side. Actual parking conditions should be monitored periodically. In addition, it is anticipated that some parking spaces will be available on the existing Kirtley property near the warehouse building. Existing parking occupancy data could not be collected at the existing office and warehouse buildings on the Kirtley property as they are both currently vacant. However, parking generation potential was determined based on ITE rates. ITE Code 710 (General Office) was used to generate parking demand for the 4,300 sf office building. ITE Code 150 (Warehousing) was used to generate parking demand for the 23,000 sf warehouse building. Table 4 below summarizes the hourly parking generation potential of these facilities. Table 4— Hourly Parking Generation Potential of Existing Kirtley Property Hour Beginning Office Parking Demand Warehouse Parking Demand Total Parking Demand Unoccupied Parking Spaces Actual Parking Spaces Available (90 °l0) Page 11 Northndge Development January 25, 2008 A total of 59 parking spaces (21 office and 38 warehouse) are currently provided on the Kirtley property. With the proposed modifications, 48 total parking spaces (10 office and 38 warehouse) will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 48 spaces. Table 4 indicates that at least 21 parking spaces will be available on the Kirtley property, even during peak times. The UVA Health Services Foundation may choose to allow LTAC employees to park near the Kirtley warehouse to reduce the number of employees that must be accommodated at an off -site or satellite facility. Page 12 Northndge Development 5.o Traffic Generation January 25. 2008 Traffic generation potential for the proposed development was determined using traffic generation rates published in Trip Generation (Institute of Transportation Engineers [ITE], V Edition, 2003). 5.1 Proposed Development Trip Generation Table 5 summarizes the estimated traffic generation potential for the proposed development under the future build -out (2010) scenario. Trip Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. TTE Code 620 (Nursing Home) was used for the LTAC due to low peak hour and daily traffic generation observed at existing LTAC facilities. TTE Code 720 (Medical- Dental Office Building) was used to approximate the trip generation potential of the Radiology Support Services. Table 5— Proposed Development Trip Generation —Full Build -out ITE AM Code Description Size Unit Daily In 620 Long Term Acute Care 54,000 sf 329 *14 Peak Hour Out 7 PM Total In 21 11 Peak Hour Out Total 12 23 720 Radiology Support Services 8,000 sf 289 16 4 20 8 22 30 Total New Site Generated Trips 618 30 11 41 19 34 53 Note: A directional distribution of 69% entering and 31% exitine was assumed based on AM Peak Hour of the Generator data using "beds" as an independent variable. Table 5 indicates the proposed development having the potential to generate a total of 618 new daily trips, 41 of those occurring in the AM peak hour and 53 occurring in the PM peak hour. Although 46 employees will be parked at an off -site location, it is unclear at this time whether they can be accommodated at a nearby property or if they will utilize satellite parking with shuttle service. For the purposes of the traffic analysis, in order to analyze a worse case scenario, no trip reductions were applied to the estimated trip generation potential to account for employees that may be shuttled from satellite parking locations. It should be noted that while assigning the full trip generation potential to the study area intersections will appropriately account for additional traffic on Ivy Road, it will overstate the turning movements at the site driveways. Page 13 Northridge Development January 25, 2008 In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by UVA and will be maintained with similar uses by the UVA Health Services Foundation. Because these buildings were occupied by their former tenants at the time of the data collection (November 2006), trips associated with these uses are included in the existing traffic counts and will not be generated as new site trips. Page 14 F1 tNorthtidge Development )anua7 25, 2008 6.o Traffic Distribution The directional distribution and assignment of trips generated by a development is typically based on a review of existing roadway volumes, an understanding of travel patterns within the study area, and from assumptions of anticipated shifts in travel patterns due to the construction of the development. In the case of the proposed development, directional distribution was determined from the existing Northridge building, a similar land use. The following distribution applies to the 2010 development condition: 85% to /from the east on Ivy Road 15% to /from the west on Ivy Road Site traffic distribution is illustrated in Figure 3.

Northridge Development January 25, 2008 7.0 Site Access and Traffic Assignment Ivy Road (U.S. Route 250) will be the primary corridor providing access to the proposed development. The main entrance to the proposed building will be located on the east side of the building at the parking (ground) level. As a result, all visitors, patients, and staff will utilize the Northridge Main Entrance, which will also continue to serve the existing Northridge building. An ambulance/transfer vehicle drop -off will be provided on the west side of the building. Due to the elevation change over the two adjacent properties, this entrance will provide direct access to the second floor Long Term Acute Care (LTAC) facility. The existing Service Entrance will therefore provide access to a very small portion of proposed LTAC traffic and will continue to provide access to the existing warehouse and two-story office buildings. r It is assumed that approximately 5% of LTAC traffic will utilize the Service Entrance. All other proposed Northridge traffic will utilize the Northridge Main Entrance. Page 17 Northridge Development lanuarn. O) 2008 8.o Projected Traffic Volumes 8.1 Historic Traffic Growth Historic traffic growth is the increase in traffic volumes due to usage increases and non - specific growth throughout an area. One method of dete reasonable growth rates for an area is to research past traffic counts for a roadway or intersection. The following are traffic counts from the VDOT count program: Ivy Road 2006 - 14,000 vehicles per day (vpd) 2005 - 15,000 vpd 2004- 14,000 vpd 2003 - 13,000 vpd 2002 - 14,000 vpd 2001 - 12,000 vpd Based on the VDOT data, a background growth rate of 5.5% was used in this study. No other major developments that need to be considered in the analysis are anticipated in the vicinity of the proposed development. Any redevelopment or smaller development in the site's vicinity is assumed to be accounted for by the background growth factor. 8.2 Total Traffic To obtain total 2010 build -out traffic volumes, existing (November 2006) traffic volumes were incrementally increased using the aforementioned background growth rate. Existing turning movement volumes were increased by 17.4 percent to reflect future background traffic growth for three years (to 2010). Once background traffic volumes were established, traffic associated with the proposed development was added to develop 2010 total (build -out) traffic volumes. The following figures illustrate future turning movement volumes: Figure 4 -2010 AM peak hour Figure 5 --2010 PM peak hour Page 18 North Not to Scale UCCE CUj U C C CUc6 CLU p 4) U U Z N c7 NRN 1 26 (1) [27] 115 (24) [139] 4 469 (2) [471] f— 475 (1) [476] 7] (0) 7 __$ [21] (5) 16 —1I Ivy Road 1155] (5) 1150 —1 [1208] (1) 1207 — Legend 0 - Unsignalized Intersection XX (XX) [XX] - Background (Site) [Total] Peak Hour Volumes PPP1 Northridge Development Future (2010) AM Peak FIGURE Kimley -Horn Albemarle County, Virginia Hour Traffic Volumes 4,and Associates, Inc.

Intersection turning movement counts were used with information about the number of lanes and traffic control to determine existing and future levels of service. Level of service (LOS) describes traffic conditions —the amount of traffic congestion —at an intersection or on a roadway. LOS ranges from A to F —A indicating a condition of little or no congestion and F a condition with severe congestion, unstable traffic flow, and stop- and -go conditions. For intersections, LOS is based on the average delay experienced by all traffic using the intersection during the busiest peak) 15- minute period. LOS A through D are generally considered acceptable. Each of the aforementioned scenarios was analyzed during the weekday AM and PM peak hours. The results are presented in the following summaries, and supporting calculations are presented in the Appendix. Page 21 Northndge Development January 25, 2008 9.1 Ivy Road /Northridge Main Entrance This unsignalized intersection currently provides the following laneage: Ivy Road (eastbound} --one exclusive through lane and one exclusive left -turn lane Ivy Road (westbound)- -one exclusive through lane and one exclusive right -turn lane Northridge Main Entrance (southbound) --one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS D and F during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is expected to worsen to LOS E during the AM peak hour. Under the same conditions, delay is anticipated to increase significantly during the PM peak hour such that the movement continues to operate at LOS F. Table 6 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table "vy Road/Northridge Main Entrance Intersection Unsignalized LOS Under future traffic conditions, operations on Ivy Road will not change appreciably. Levels of service for all movements except for the southbound (site driveway) left -tum movement will not change under future traffic conditions. To improve operations for the southbound (site driveway) approach would require that a traffic signal be installed. Traffic signal warrant analyses were performed at this location referencing the Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition to evaluate the need for traffic signalization under existing (2006) conditions. According to the MUTCD, a traffic control signal should not be installed unless one or more of the signal warrants in the MUTCD are met. However, "the satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal." The three main warrants are as follows: Page 22 1 aw Warrant 3 (Peak Hour Volume volumes meet or exceed the necessary thresholds for this warrant during four hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for one hour. These warrants are based on mainline and side street traffic volumes, number of travel lanes (one per approach), and mainline travel speed (45 mph). As is common practice, right -turn volumes were excluded from the projected side street volumes because an exclusive right -turn lane is provided Detailed warrant analyses are included in the Appendix. Based on existing ADT volumes and four hours of turning movement volumes, analyses indicated that the intersection of Ivy Road and the Northridge Main Entrance currently warrants a traffic signal. Although a full 12 -hour turning movement count was not performed at this time, signal warrants were evaluated using reasonable estimates of the hourly distribution of outbound left- turn volumes based on ITE daily trip generation. Existing peak hour inbound and outbound trips very closely mirror estimated ITE trip generation for the existing Northridge building. bw With this signal and based on projected traffic volumes, vehicle queues in eastbound and westbound (Ivy Road) through lanes will not extend through adjacent intersections /driveways and create blockages. Table 7 summarizes signalized level of service at this intersection for future scenarios. 1 Page 23 Northridge Development January 25, 2006 Warrant 1 (Eight -Hour Vehicular Volume)--is satisfied if ONE of the following conditions exists for any eight hours of a day: Condition A (Minimum Vehicular Volume volumes do not meet or exceed the necessary thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. Condition B (Interruption of Continuous Traffic volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant rr.to be met, volume thresholds must be at or above thresholds for eight hours. Combination of Condition A and B (Combination of Condition A and B)— volumes do not meet or exceed the necessary combination of thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. Warrant 2 (Four -Hour Vehicular Volume )--volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for four hours. aw Warrant 3 (Peak Hour Volume volumes meet or exceed the necessary thresholds for this warrant during four hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for one hour. These warrants are based on mainline and side street traffic volumes, number of travel lanes (one per approach), and mainline travel speed (45 mph). As is common practice, right -turn volumes were excluded from the projected side street volumes because an exclusive right -turn lane is provided Detailed warrant analyses are included in the Appendix. Based on existing ADT volumes and four hours of turning movement volumes, analyses indicated that the intersection of Ivy Road and the Northridge Main Entrance currently warrants a traffic signal. Although a full 12 -hour turning movement count was not performed at this time, signal warrants were evaluated using reasonable estimates of the hourly distribution of outbound left- turn volumes based on ITE daily trip generation. Existing peak hour inbound and outbound trips very closely mirror estimated ITE trip generation for the existing Northridge building. bw With this signal and based on projected traffic volumes, vehicle queues in eastbound and westbound (Ivy Road) through lanes will not extend through adjacent intersections /driveways and create blockages. Table 7 summarizes signalized level of service at this intersection for future scenarios. 1 Page 23 Northridge Development Januarc 25, 2008 Table 7 -I-vy Road/Northridge Main Entrance Intersection Signalized LOS To provide acceptable LOS at this intersection as indicated in Table 7, the following are recommended: Maintain existing laneage Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Figure 6 shows recommended laneage and traffic control at this intersection. Detailed level of service calculations are provided in the Appendix. Page 24 Northridge Development January 25, 2008 9.2 Ivy Road /Service Entrance This unsignalized intersection currently provides the following laneage: Ivy Road (eastbound}- -one exclusive through lane and one exclusive left -turn lane Ivy Road (westbound}- -one exclusive through lane and one exclusive right -turn lane Service Entrance (southbound) ---one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS C and D during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is anticipated to worsen to LOS D during the AM peak hour and maintain LOS D during the PM peak hour. Operations on Ivy Road, including the eastbound left -turn movement into the site, will be negligibly impacted by the development. Table 8 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table 8 —Ivy Road/Service Entrance Intersection Unsignalized LOS No improvements are recommended at this intersection. Detailed level of service calculations are provided in the Appendix.

In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended:- Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off-site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off-site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minimally increase traffic volumes on Ivy Road and at study area intersections. Recommended improvements will mitigate development traffic impacts. To maintain acceptable traffic operations at study intersections, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two-way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Ivy Road/Service Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and diffi( discern) ppw-MF1 FIGURENorthridgeDevelopmentRecommended Kimley -Horn Albemarle County, Virginia Roadway Laneage 6 and Associates, Inc.

Figure 1 illustrates the site location. The proposed development is planned to include a new, 62,000 square foot (sf) building consisting of a 54,000 sf long term acute care (LTAC) facilityARMA bedsland 10 pediatric bedA and 8,000fsfofradiologysupportservices. In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by the University of Virginia (UVA) and will be maintained with similar uses by the UVA Health Services Foundation. Parking to the development besupportproposedcannot provided solely on the existing Northridge site. In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended: Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off -site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off -site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minima increase the volume of traffic on Ivy Road and at study area intersections. To mitigate potential operational issues and provide for acceptable levels of service throughout the study area, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two -way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Page 1 Nortlhndge Development januan 25, 2008 Ivy Road/Service Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and difficult to discern) Page 2 1 1 Northridge Development January 25, 2008 1 2.0 Introduction The Northridge Development is proposed to be located on Ivy Road adjacent to the existing Northridge building in Albemarle County, Virginia. In general, the site is bounded by a Volvo dealership to the west, a Fleet Operations building to the east, Ivy Road to the south, and the CSX Railroad to the north. As shown in Figure 1, Ivy Road runs in an east/west direction and connects to the U.S. Route 29/250 Bypass to the east of the site. The proposed development is planned to include an approximately 62,000 square foot (sf) building to contain the following: Long term acute care facility- 54,000 sf (40 adult beds and 10 pediatric beds) Radiology support services -8,000 sf The anticipated construction and occupancy timeline for the proposed building is approximately The proposed building is planned to occupy an undeveloped portion of the existing Northridge property, as well as part of the existing Kirtley property, which was previously occupied by TJMF Distribution Center and the Lee Tennis Products office building.

U.S. Route 250 runs parallel to Interstate 64 between Richmond and Staunton, from which point it continues northwest into West Virginia, eventually connecting to Interstate 79. Regionally, Ivy Road provides access to the U.S. Route 29/250 Bypass and to the University of Virginia. Within the study area, Ivy Road is a three -lane roadway with a two -way left -turn lane (TWLTL). Several signalized intersections are located along Ivy Road, as well as numerous unsignalized driveways. The posted speed limit on Ivy Road is 45 miles per hour. Traffic counts estimated by the Virginia Department of Transportation (VDOT) indicate that in 2006, Ivy Road was carrying approximately 14,000 vehicles per day (vpd) in the vicinity of the proposed development. Traffic counts were conducted by Kimley -Hom and Associates, Inc. in November 2006 on Ivy Road, and indicated that the avig Mg daily traffic (ADT) volume was approxiifSately Existing roadway laneage for study area roadways and intersections is illustrated in Figure 2. r Page 5 3.0 Project Background 3.1 Study Area The study area for this analysis includes the following roadways and intersections: Roadways Ivy Road U.S. Route 250) Intersections Ivy Road/Northridge Main Entrance (existing Northridge building) Ivy Road/Service Entrance (former TJMF Distribution Center and Lee Tennis Products) 3.2 Existing Land Use ILand use and development in the study area include medical, office, commercial, and industrial uses.

The parking lot at the existing Northridge building will be modified to accommodate the main entrance and drop -off for the proposed Northridge development. Likewise, the existing parking lot adjacent to the office building will be modified to accommodate a drop -off for patient transfer vehicles. Parking generation potential for the existing and proposed land uses was calculated using parking generation rates published in Parking Generation (Institute of Transportation Engineers [ITE], 3" Edition, 2004) to determine if the existing parking areas will be adequate to support the addition of the proposed Northridge development. 4.1 Existing Northridge Building Parlung Occupancy ITE Code 720 (Medical - Dental Office Building) was used to approximate the parking generation potential of the existing 58,770 sf Northridge building. In addition, Kimley -Horn verified existing parking inventory and collected actual occupancy data on Wednesday, December 5, 2007 at 10:00 AM, 12:00 PM, 2:00 PM, and 4:00 PM. Staff and visitor parking were counted separately; however, they are combined for analysis purposes. Parking demand generated by ITE was supplemented with actual occupancy counts, and the surrounding hours were adjusted accordingly. The peak occupancy count was nearly identical to the peak parking demand generated by ITE; however, actual occupancy later in the afternoon was less than generated by ITE. Table 1 below summarizes the parking demand at the Northridge building by the hour and indicates the number of remaining (unoccupied) parking spaces. Any facility that is at least 90% occupied is considered "full" by industry standards to account for circulation, turnover, and access. The number of available spaces has accordingly been reduced to account for 90% occupancy rather than 100% in order to maintain some surplus for circulation and turnover. Page 8 Northridge Development Table 1— Hourly Parking Demand at Existing Northridge Building Januarn 25, 2008 Hour Beginning 6:00 AM Parking Demand 20 Unoccupied Parking Spaces 233 Actual Parking Spaces 9i 208 7:00 AM 32 221 196 8:00 AM 102 151 126 9:00 AM 175 78 53 10:00 AM 206 47 22 11:qAM 206 47 22 12:160 93 68 1:0164 89 64 2:0177 76 51 3:163 90 65 4:00 PM 132 121 96 5:00 PM 100 153 128 6:00 PM 75 178 153 A total of 254 parking spaces (88 staff and 166 visitor) are currently provided at the Northridge site. With the proposed modifications, 253 total parking spaces will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 253 spaces. Table 1 indicates that only 22 parking spaces are available during the peak demand period (10:00 AM to 12:00 PM). 4.2 Proposed Northridge Development Parking Generation Parking Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. ITE Code 620 (Nursing Home) was used for the LTAC due to low peak hour and daily parking/traffic generation observed at existing LTAC facilities. Parking generation for the LTAC based on gross floor area (54,000 sf) results in a demand significantly higher than if generated based on beds (50 beds). To provide a worse case scenario, parking demand was generated based on gross floor area. ITE Code 720 (Medical- Dental Office Building) was used to generate parking demand for the 8,000 sf Radiology Support Services. Table 2 below summarizes the parking generation potential of the proposed Northridge development by the hour.

Although the peak parking period occurs later than at the existing Northridge facility, the parking demand was compared to available spaces at the existing facility to determine whether additional parking spaces will be required. Table 3 summarizes the total parking demand and availability. Table 3— Hourly Parking Space Allocation Hour Beginning 6:00 AM Existing Northridge Parking Demand 20 Existing Parking Spaces Available i 208 Proposed Northridge Development Parking 23 Net Parking Spaces 185 7:00 AM 32 196 31 165 8:00 AM 102 126 45 82 9:00 AM 175 53 59 6 10:00 AM 206 22 62 40 11:00 AM 206 22 63 41 12:00 PM 160 68 59 9 1:00 PM 164 64 58 6 2:00 PM 177 51 82 31 3:00 PM 163 65 85 20 4:00 PM 132 96 57 39 5:00 PM 100 128 35 93 6:00 PM 75 153 23 130 As indicated in Table 3, there is not sufficient parking supply at the existing Northridge building to accommodate the parking demand from the proposed Northridge development during the peak parking period from 11:00 AM to 12:00 PM. In order to accommodate the additional parking r Page 10 t. 1 1 Northridge Development January 25, 2008 1 demand and maintain a 10% surplus to account for circulation and turnover, an additional 4 I parking spaces are needed on the Northridge site. Using a parking rate of 0.9 vehicles per employee (ITE Code 620), this results in the need to relocate approximately 46 employees to off - site or satellite parking. The UVA Health Services Foundation has indicated that they will commit to relocating at least 46 employees by providing either off -site parking at another nearby prop or satellite parking with shuttle service as an extension of the existing parking and transportation system Shuttle service is currently provided at the Northridge building. If the 46 employees cannot be accommodated at a nearby property, satellite parking with shuttle service could be utilized by either existing Northridge employees or future LTAC employees because parking will be shared between the two facilities. It should be noted that the potential parking demand for the proposed Northridge development was generated on the conservatively high side. Actual parking conditions should be monitored periodically. In addition, it is anticipated that some parking spaces will be available on the existing Kirtley property near the warehouse building. Existing parking occupancy data could not be collected at the existing office and warehouse buildings on the Kirtley property as they are both currently vacant. However, parking generation potential was determined based on ITE rates. ITE Code 710 (General Office) was used to generate parking demand for the 4,300 sf office building. ITE Code 150 (Warehousing) was used to generate parking demand for the 23,000 sf warehouse building. Table 4 below summarizes the hourly parking generation potential of these facilities. r Table 4— Hourly Parking Generation Potential of Existing Kirtley Property Hour Beginning Office Parking Demand Warehouse Parking Demand Total Parking Demand Unoccupied Parking Spaces Actual Parking Spaces Available (90 %) i i Page 11 Northndge Development January 2-5, 2008 A total of 59 parking spaces (21 office and 38 warehouse) are currently provided on the Kirtley property. With the proposed modifications, 48 total parking spaces (10 office and 38 warehouse) will be provided in the future. The unoccupied and available parking spaces determined above are based on a supply of 48 spaces. Table 4 indicates that at least 21 parking spaces will be available on the Kirtley property, even during peak times. The UVA Health Services Foundation may choose to allow LTAC employees to park near the Kirtley warehouse to reduce the number of employees that must be accommodated at an off -site or satellite facility. Page 12 1 1 P am fl 1 Northridge Development 5.o Traffic Generation January 25, 2008 Traffic generation potential for the proposed development was determined using traffic generation rates published in Trip Generation (Institute of Transportation Engineers [ITE], 7 Edition, 2003). 5.1 Proposed Development Trip Generation Table 5 s the estimated traffic generation potential for the proposed development under the future build -out (2010) scenario. Trip Generation does not provide specific rates for Long Term Acute Care (LTAC) facilities or for Radiology Support Services as proposed for the development. Based on conversations with the architect, equivalent land uses were determined that would represent similar travel patterns for the proposed uses. ITE Code 620 (Nursing Home) was used for the LTAC due to low peak hour and daily traffic generation observed at existing LTAC facilities. ITE Code 720 (Medical- Dental Office Building) was used to approximate the trip generation potential of the Radiology Support Services. Table 5— Proposed Development Trip Generation —Full Build -out Table 5 indicates the proposed development having the potential to generate a total of 618 new AR"ps, 41 of those occurring in the AM peak hour and 53 occurring in the PM peak hour. Although 46 employees will be parked at an off -site location, it is unclear at this time whether they can be accommodated at a nearby property or if they will utilize satellite parking with shuttle service. For the purposes of the traffic analysis, in order to analyze a worse case scenario, no trip R reductions were applied to the estimated trip generation potential to account for employeesthat 7 nay be shuttled from satellite parking locations. It should be noted that while assigning the full trip generation potential to the study area intersections will appropriately account for additional traffic on Ivy Road, it will overstate the turning movements at the site driveways. Page 13 1 Note: A directional distribution ot69% entering and 31% exiting was assumed based on AM Peak Hour of the Generator data using "beds" as an independent variable. IM biNorthridge Development January 25, 2008 In the vicinity of the proposed development (located on the Kirtley property), a small office building and a warehouse have been acquired by UVA and will be maintained with similar uses by the UVA Health Services Foundation. Because these buildings were occupied by their former tenants at the time of the data collection (November 2006), trips associated with these uses are included in the existing traffic counts and will not be generated as new site trips. u. 1 1 n i 1 Page 14 Northridge Development January 25, 2008 6.o Traffic Distribution The directional distribution and assignment of trips generated by a development is typically based 1 on a review of existing roadway volumes, an understanding of travel patterns within the study area, and from assumptions of anticipated shifts in travel patterns due to the construction of the development. In the case of the proposed development, directional distribution was determined from the existing Northridge building, a similar land use. The following distribution applies to the 2010 development condition: 85% tolfrom the east on Ivy Road 15% to /from the west on Ivy Road Site traffic distribution is illustrated in Figure 3. 1 1 u F1 1 1 Page 15 ppl- = FIGURENorthridgeDevelopment Kimley -Horn Albemarle County, Virginia Trip Distribution 3 and Associates, Inc.

The main entrance to the proposed building will be located on the east side of the A. building at the parking (ground) level. As a result, all visitors, patients, and staff will utilize the Northridge Main Entrance, which will also continue to serve the existing Northridge building. An ambulance/q4sfa vehicle drop -off will be provided on the west side ofth eutlding. Due to the elevation change over the two adjacent properties, this entrance will provide direct access to the second floor Long Term Acute Care (LTAC) facility. The existing Service Entrance will therefore provide access to a very small portion of proposed LTAC traffic and will continue to provide access to the existing warehouse and two -story office buildings. It is assumed that approximately 5% of LTAC traffic will utilize the Service Entrarke. All other Iproposed Northridge traffic will utilize the Northridge Main Entrance. 1 1 Page 17 Nortlandge Development )anuanc 25, 2008 8.o Projected Traffic Volumes 8.1 Historic Traffic Growth Historic traffic growth is the increase in traffic volumes due to usage increases and non - specific growth throughout an area. One method of determining reasonable growth rates for an area is to research past traffic counts for a roadway or intersection. The following are traffic counts from the VDOT count program: Iiy Road 2006 - 14,000 vehicles per day (vpd) 2005 - 15,000 vpd 2004 - 14,000 vpd 2003 - 13,000 vpd 2002 - 14,000 vpd 2001 - 12,000 vpd Based on the VDOT data, a background growth rate of 5.5% was used in this study. No other major developments that need to be considered in the analysis are anticipated in the vicinity of the proposed development. Any redevelopment or smaller development in the site's vicinity is assumed to be accounted for by the background growth factor. 8.2 Total Traffic To obtain total 2010 build -out traffic volumes, existing (November 2006) traffic volumes were incrementally increased using the aforementioned background growth rate. Existing turning movement volumes were increased by 17.4 percent to reflect future background traffic growth for three years (to 2010). Once background traffic volumes were established, traffic associated with the proposed development was added to develop 2010 total (build -out) traffic volumes. The following figures illustrate future turning movement volumes: Figure 4-2010 AM peak hour Figure 5--2010 PM peak hour Page 18 North Not to Scale CDUC6 C W U C C O C W rn Qv .c s' 0U) Z jF 0N ; N C7 d NN 1 26 (1) [271 k 115 (24) [139]C y 4 — 469 (2) [471] 4 475 (1) [476] 7 —1 [21] (5) 16 Ivy Road 1155] (5) 1150 —10 [1208] (1) 1207 —1 Legend 0 - Unsignalized Intersection XX (XX) [XX] - Background (Site) [Total] Peak Hour Volumes F1kh.- = Northridge Development Future (2010) AM Peak FIGURE Kimley -Horn Albemarle County, Virginia Hour Traffic Volumes 4,and Associates, Inc.

Intersection turning movement counts were used with information about the number of lanes and traffic control to determine existing and future levels of service. Level of service (LOS) describes traffic conditions the amount of traffic congestion —at an intersection or on a roadway. LOS ranges from A to F —A indicating a condition of little or no congestion and F a condition with severe congestion, unstable traffic flow, and stop- and -go conditions. For intersections, LOS is based on the average delay experienced by all traffic using the intersection during the busiest peak) 15- minute period. LOS A through D are generally considered acceptable. Each of the aforementioned scenarios was analyzed during the weekday AM and PM peak hours,. The results are presented in the following summaries, and supporting calculations are presented in the Appendix. Page 21 Northridge Development 9.1 Ivy Road /Northridge Main Entrance This unsignalized intersection currently provides the following laneage: Januan 25, 2008 Ivy Road (eastbound) ---one exclusive through lane and one exclusive left-turn lane Ivy Road (westbound)- -one exclusive through lane and one exclusive right -turn lane Northridge Main Entrance (southbound)- -one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS D and F during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is expected to worsen to LOS E during the AM peak hour. Under the same conditions, delay is anticipated to increase significantly during the PM peak hour such that the movement continues to operate at LOS F. Table 6 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table 6 —Ivy Road/Northridge Main Entrance Intersection Unsignalized LOS Under future traffic conditions, operations on Ivy Road will not change appreciably. Levels of service for all movements except for the southbound (site driveway) left -turn movement will not change under future traffic conditions. To improve operations for the southbound (site driveway) approach would require that a traffic signal be installed. Traffic signal warrant analyses were performed at this location referencing the Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition to evaluate the need for traffic signalization under existing (2006) conditions. According to the MUTCD, a traffic control signal should not be installed unless one or more of the signal warrants in the MUTCD are met. However, "the satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal." The three main warrants are as follows: Page 22 AM delay Peak Hour in seclveh) LOS PM Peak Hour LOS Movement 2006 Existing 2010 No Build 2010 delay 2006 in seclveh 2010 2010 Build -out Existing No Build Build -out Under future traffic conditions, operations on Ivy Road will not change appreciably. Levels of service for all movements except for the southbound (site driveway) left -turn movement will not change under future traffic conditions. To improve operations for the southbound (site driveway) approach would require that a traffic signal be installed. Traffic signal warrant analyses were performed at this location referencing the Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition to evaluate the need for traffic signalization under existing (2006) conditions. According to the MUTCD, a traffic control signal should not be installed unless one or more of the signal warrants in the MUTCD are met. However, "the satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal." The three main warrants are as follows: Page 22 Northridge Development Januaran' 25, 2005 Warrant 1 (Eight -Hour Vehicular Volume)—is satisfied if ONE of the following conditions exists for any eight hours of a day: o Condition A (Minimum Vehicular Volume}— volumes do not meet or exceed the necessary thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. o Condition B (Interruption of Continuous Traffic}— volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. o Combination of Condition A and B (Combination of Condition A and B)— volumes do not meet or exceed the necessary combination of thresholds for this warrant during any hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for eight hours. Warrant 2 (Four -Hour Vehicular Volume} -- volumes meet or exceed the necessary thresholds for this warrant during eight hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for four hours. Warrant 3 (Peak Hour Volume )--volumes meet or exceed the necessary thresholds for this warrant during four hours of the day. For the warrant to be met, volume thresholds must be at or above thresholds for one hour. These warrants are based on mainline and side street traffic volumes, number of travel lanes (one per approach), and mainline travel speed (45 mph). As is common practice, right -turn volumes were excluded from the projected side street volumes because an exclusive ri ght -turn lane is provided. Detailed warrant analyses are included in the Appendix. Based on existing ADT volumes and four hours of turning movement volumes, analyses indicated that the intersection of Ivy Road and the Northridge Main Entrance currently warrants a traffic signal. Although a full 12 -hour turning movement count was not performed at this time, signal warrants were evaluated using reasonable estimates of the hourly distribution of outbound left - turn volumes based on ITE daily trip generation. Existing peak hour inbound and outbound trips very closely mirror estimated ITE trip generation for the existing Northridge building. With this signal and based on projected traffic volumes, vehicle queues in eastbound and westbound (Ivy Road) through lanes will not extend through adjacent intersections /driveways and create blockages. Table 7 summarizes signalized level of service at this intersection for future scenarios. Page 23 Northndge Development January 25, 2008 Table 7 —Ivy Road/Northridge Main Entrance Intersection Signalized LOS To provide acceptable LOS at this intersection as indicated in Table 7, the following are recommended: Maintain existing laneage Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Figure 6 shows recommended laneage and traffic control at this intersection. Detailed level of service calculations are provided in the Appendix. Page 24 Northridge Development lanuare 25, 2008 9.2 Ivy Road /Service Entrance This unsignalized intersection currently provides the following laneage: Ivy Road (eastbound) --one exclusive through lane and one exclusive left -turn lane Ivy Road (westbound)– one exclusive through lane and one exclusive right -turn lane Service Entrance (southbound) --one exclusive left -turn lane and one exclusive right -turn lane Under existing conditions, the southbound (site driveway) left -turn movement operates at LOS C and D during the AM and PM peak hours, respectively. With the increment of background traffic growth and traffic associated with the proposed development, this movement is anticipated to worsen to LOS D during the AM peak hour and maintain LOS D during the PM peak hour. Operations on Ivy Road, including the eastbound left -turn movement into the site, will be negligibly impacted by the development. Table 8 indicates levels of service and delays for the intersection under existing (2006), 2010 no build, and 2010 build -out conditions. Table 8 —Ivy Road/Service Entrance Intersection Unsignalized LOS No improvements are recommended at this intersection. Detailed level of service calculations are provided in the Appendix. Page 25 Northndge Development ]anua7 25, 2008 zo.o Conclusions and Recommendations Parking to support the proposed development cannot be provided solely on the existing Northridge site. In order to provide sufficient parking for existing Northridge patients and future LTAC /radiology patients, the following are recommended: Relocate at least 46 employees (existing Northridge or future LTAC /radiology) by providing either off -site parking at another nearby property or satellite parking with shuttle service as an extension of the existing parking and transportation system Consider allowing up to 20 LTAC /radiology employees to park in the surplus spaces on the existing Kirtley property near the warehouse building and reduce the off -site or satellite parking accordingly Periodically monitor actual parking conditions and adjust off -site or satellite parking operations accordingly The number of new trips generated by the site is considerably low and will minimally increase traffic volumes on Ivy Road and at study area intersections. Recommended improvements will mitigate development traffic impacts. To maintain acceptable traffic operations at study intersections, the following are recommended: Ivy Road/Northridge Main Entrance Maintain existing laneage Restripe existing pavement markings (existing markings are faded and difficult to discern) Consider modifying current pavement markings in center lane (two -way left -turn lane) by striping an exclusive eastbound left -turn lane Conduct a 12 -hour turning movement count and, if signal warrants are met, install a traffic signal to facilitate southbound movements from the Northridge Main Entrance Ivy Road/Service Entrance Maintain existing laneage and traffic control Restripe existing pavement markings (existing markings are faded and difficult to discern) Page 26 FIGURE Northridge Development Recommended Kimley -Horn Albemarle County, Virginia Roadway Laneage 6 and Associates, Inc.

Gary Original Message---- - From: Ammy George [ mailto:Ammy.George @timmons.com] Sent: Thursday, January 31, 2008 9:48 AM To: dbenish @albemarle.org Cc: gel3w @virginia.edu; Sam.Saunders @timmons.com Subject: UVA LTACH Sanitary Sewer Study Good morning David, I have attached a copy of the Sanitary Sewer Study as an answer to the following questions can the Kirtley warehouse be served by gravity sewer and what we are proposing to do? As demonstrated by the enclosed plan, the Kirtley warehouse building can be served by gravity sewer. But due to the fact that this would entail removing many of the existing trees at the rear of the Northridge property as well as having construction activity on a 2:1 slope, we have decided to maintain the force main that runs from the Kirtley warehouse. The force main would be tied into the plumbing of the existing brick office building located at the front of the Kirtley property which is connected to the public sewer system. We feel solution is in line with the comprehensive plan and is ecologically sensitive to the surrounding properties. If you have any questions or comments, please feel free to call me.
