The proposed school will be an addition to the existing elementary school and campus facilities that already exist on Faulconer Drive in Albemarle County, Virginia. The proposed Middle School is scheduled to open in the fall of 2010. The following steps were taken to determine the potential traffic impacts associated with the proposed Middle School: 1. Background Data — Background AM (8:00 a.m. — 9:00 a.m.) and PM (3:30 p.m. — 4:30 p.m.) peak hour turning movement counts were obtained at the following five (5) locations: 1. Route 250 and Old Ivy Road 2. Route 250 and Canterbury Road/Route 601 3. Route 601 and Old Garth Road/Old Ivy Road 4. Old Ivy Road and Faulconer Drive 5. Faulconer Drive and Route 601/Route 250 Off-ramp These time periods were established in conjunction with school officials, Albemarle County and the Virginia Department of Transportation (VDOT) and coincide with the anticipated start and dismissal times of the proposed Middle School. se& ( �'�glt;y3t 2. Background Traffic Projections — Background traffic volumes were projected ahead through 2010, the build out year for the Middle School, using a 2% annual growth rate. This growth rate was specified by Albemarle County and approved by VDOT. 3. Trip Generation — Traffic generated by the Middle School was estimated using the 7th edition of the Institute of Transportation Engineer's Trip Generation Handbook. Trip _ _ d generation was calculated using the number of students as the independent variable. A NAG 30% reduction to the estimated trip generation was applied based on information #(.5 provided by STAB officials pertaining to families with siblings attending both the Lower and Middle Schools 4. Traffic Distribution and Projections — The distribution of school-generated traffic was estimated based on the distribution of the student population. STAB representatives provided a breakdown of student residences in relation to the proposed Middle School. u)k"h0 1Jt; 5. Left and Right Turn Lane Analyses —Turn lane analyses were conducted using the Virginia Department of Transportation's (VDOT) Road Design Manual. 1 STAB-Middle School TIA 6. Traffic Capacity Analysis — Level of service calculations for the intersections within the study area were performed using SYNCHRO Version 6 (Build 614). This computer program calculates delay based on techniques outlined in the 2000 Highway Capacity Manual. The following intersections were analyzed: 1. Route 250 and Old Ivy Road 2. Route 250 and Canterbury Road/Route 601 3. Route 601 and Old Garth Road/Old Ivy Road 4. Old Ivy Road and Faulconer Drive 5. Faulconer Drive and Route 601/Route 250 Off-ramp 7. Review of Proposed Improvements — Proposed roadway improvements required to accommodate projected background and site-generated traffic were evaluated relative to VDOT standards. STUDY LIMITS The planned 250-student Middle School is proposed to be built on the existing STAB Lower Campus in Albemarle County, Virginia (see Figure 1). Access to the Lower Campus will remain as it exists today; Faulconer Drive will serve as the sole point of ingress and egress. A preliminary site plan depicting the Middle School is shown in Figure 2. Given the traffic associated with the proposed development, it, distribution, and the existing traffic volumes along the roadway corridors adjacent to the site, Albemarle County and VDOT have indicated that the traffic study shall be limited to the unsignalized intersection adjacent to the Faulconer Road/Route 601 intersection and two signalized intersections on the US Route 250 (Ivy Road) corridor at Canterbury Road/Route 601 and Old Ivy Road. ochA445) vo,d,412--todeil 19(1/WL4(1._ fopet. td oPi °' ci(¢$1.' , 64)161)tjlr 111 87/) liAfrpt0A, VP- 00);(01 ,,,,ic-)fr.t-e-) ,/ 'ef&-j tiv 4I o t" Wit;" 611 cLt ✓a"�" ^ n� t 2 LEGEND: f Existing Road 0_ Railroad � — Proposed Site _ SITE29 c)„,ry / `fs . n •***t t; Rte 601 , .... c'fi, / 250 a °c IVY Rd ��P / �)C %. �� Faulconer Dr , 9r L.....1 o4 c�e / a ID '•.

The existing intersection geometry within the study area is summarized on Figure 3. Background turning movement counts were obtained at the following five intersections: 1. Route 250 and Old Ivy Road 2. Route 250 and Canterbury Road/Route 601 3. Route 601 and Old Garth Road/Old Ivy Road 4. Old Ivy Road and Faulconer Drive 5. Faulconer Drive and Route 601/Route 250 Off-ramp These locations are shown graphically on Figure 4. This data was collected between January 22nd and January 24th, 2008 during both AM and PM peak hours. AM data was collected from 8:00 to 9:00 am and PM data was collected from 3:30 to 4:30 pm. These hours coincide with the anticipated start (8:40am) and dismissal (4:10pm) times of the proposed 250-student Middle School. The 2008 AM and PM peak hour directional turning movement counts are summarized on Figures 5A and 5P. The complete traffic data can be found in Appendix A. Background through traffic was projected ahead 2.0% annually through 2010 (opening year of the Middle School). Background traffic volume projections for 2010 are shown on Figures 6A and 6P. 5 LEGEND: T.�35 - Existing Road ill- 5-90 Signalized Intersection 'i 'T Unsignalized Intersection / r- Lane Configuration I29 I , Channelized Turn \%/ S Storage Length(in feet) fy es T Taper Length(in feet) `, 0/ d/ulconer c �Rdoo Dr Fc?' 74, ir A ONN ,,, • 44 4Ner _ y 9p 1-* Cn v-t. / .,)4 T-200'$_35p,___.......:S-'200,ti 1 r=120,Tcg0, s, u cn c #ft 250 o/a./., ivy kd • to NOT TO SCALE 3 a `' • Elb 2008 Existing Geometry Figure TIMMONS GROUP 3 0 YOUR VISION ACHIEVED THROUGH OURS C) LEGEND: f Existing Road wn.— Railroad Proposed Site Q Intersection to be Analyzed SITE / 6 csz .CS-Y Tr f d'a *??fic, Rte 601.... 6, 1 i ., o / boo o, 250 d f % �, Ivy Rd '•, -Po- /air / -.7,,,, s,q Faulconer Dr / 6'' '114 / _ -.. .i/ /al, / L___Th 64°' / #....),..;..........

Data provided by the school indicated that 30% of the students who attend the Middle School have a sibling that attends the Lower School; parents will be permitted to drop off both students at the earlier Lower School start time, thus reducing the traffic impacts associated with the Middle School The distribution of school-generated traffic w. estima -8 eased on the distribution of the student G � �. population. STAB representatives provided a breakdown of student residences in relation to the proposed Middle School. The estimated 2010 site traffic distributions are shown on Figures 7A i/r-) Gu'`9' and 7B. The 2010 peak hour volumes from Table 1 were multiplied by the percentages from Figures 7A and 7B to generate the 2010 site traffic volumes shown on Figures 8A and 8P. The 2010 background traffic volumes from Figures 6A and 6P were added to the 2010 site traffic volumes from Figures 8A and 8P to generate the projected 2010 total traffic volumes shown on Figures 9A and 9P. 12 Rte 601 SITE ti o IS 4 oacd�s C a 1LL Faulconer Dr lIvy Rd Sri Faulconer Dr fl 100% 15% t 9 3 CIV/' 0% 0% s 1 IIIIIIIIII Route 601 0 o p ^ , _a' a' t 5 4 o 0% ii 0/ es% t✓ 1 t4. 0% t4 85% 25% c_ Ivy R 4 0% ' 0% . 1 oo 4 0% o% d 1 ,1 4 L. o% i •)1 4 L. 0% , NOT TO SCALE . 0 3 60% o o ~ o0� S ; ; t 4 ^ ',a t 4 4 a' 0• 0% — 0°/a _ coz—� '1 r oN c J 60% "1 t r -. 0%a 60%t a' ; -. 0%; 0% t r—O 0% 60% tl .71.— 0% 0% t4 t4 60% 20% t 4- tl 25% 25% �- 1 0% i0% 4- ; ti 4 0% "' 5% f F., o "i J 4 L. 0% 6 E -. 0% —. 0% '2.3 l ,1 2 4 a: � r---..�1 ; z ,t 1 4 a a 0% — 5% S J 40% .1 t r J 0% -.1 t r 1 -. 0%; 0% t 0% 0% t ;L. 0% 0% t4 r-7 0% 0% tl 1 1 Canterbury Rd Old Ivy Rd I 3 .• 2010 Private School Figure rb TIMMONS GROUP Entering Site Trip Distribution Percentages 7A o YOUR VISION ACHIEVED THROUGH OURS Q y Rte 601 SITE C O a` • Ica _8` 1- a Faulconer Or l/ IIVy Rd �y Faulconer Dr % 0%t� 100 t_4-: © © ya 100% 0% 1 J 1 0% t-- ' Cr Route 601 g g ,a' a' t - l a .g , 60% 4 a •1 t C o 0% t c'Y OL 83 40% t�' allt aj�Y tl 60% • ~ U 40% 0% l_ iv Rd j 60% ' 0% Y 4 40% $ 0% .— a J 4 1. 0% 4- ' J t I. 0% 1 NOT TO SCALE l - 0% —. 40% E a t 34 g . 0 .

The Highway Capacity Manual methodologies govern how the capacity analyses are conducted and how the results are interpreted. Levels of service (LOS) are determined for each part of the roadway network, with LOS A through C representing acceptable results and LOS D through F representing marginal to unacceptable results. Table 2 shows in detail how each of these levels of service are interpreted. Table 2 LEVEL OF SERVICE DEFINITIONS ROADWAY SEGMENTS OR CONTROLLED ACCESS L.O.S.

The first phase includes the improvements that are necessary due to overall traffic growth in the area based on the 2010 background traffic volumes. The second phase consists of the improvements that are required due to traffic generated by the proposed Middle School in 2010. 2010 Background(without Middle School) Each of the five intersections that were analyzed showed unacceptable levels of service under 2010 background conditions. With respect to the signalized intersection on the US Route 250 corridor, it appears that additional through lanes are necessary to handle projected traffic volumes. While the additional through lanes would significantly improve east/west traffic movement along the corridor, the minor approaches at both Route 601 and Old Ivy Road are less than desirable and somewhat limiting with respect to efficient overall traffic flow. The remaining three unsignalized intersections do not warrant the installation of traffic signals; furthermore their locations and geometrics are not suited for such an improvement. That being said, the turn lane analyses indicate that the following auxiliary lanes are warranted: • Southbound left turn lane at Route 601/Old Garth Road/Old Ivy Road — 100 ft left turn lane with 100 ft taper required • Southbound right turn lane at Route 601/Old Garth Road/Old Ivy Road — 100 ft right turn lane with 100 ft taper required • Northbound left turn lane at Route 601/Old Garth Road/Old Ivy Road — 100 ft left turn lane with 100 ft taper required • Eastbound left turn lane at Old Ivy Road/Faulconer Drive — 100 ft left turn lane with 100 ft taper required • Southbound right turn lane at Faulconer Drive/Ramp from SB US Route 29 — 100 ft right turn taper required It is recommended that the above listed turn lane improvement be considered by the County; again, these are improvements warranted by projected background traffic. 33 STAB-Middle School TIA 2010 Middle School Improvements The addition of the Middle School in 2010 is estimated to add approximately 154 total AM peak trips (85 enter, 69 exit) and 112 PM peak trips (53 enter, 59 exit). Provided the trip distribution and surrounding road network, the additional traffic will be most evident at two locations — Faulconer Drive/Old Ivy Road and Faulconer Drive/SB US 29 Off ramp. Under 2010 total traffic conditions, each of these intersections were noted as satisfying the following turn lane warrants: • Westbound right turn lane at Old Ivy Road/Faulconer Drive— 100 ft right turn taper • Southbound right turn lane at Faulconer Drive/Ramp from SB US Route 29 — 100 ft right turn lane with 100 ft taper The westbound right turn taper at Old Ivy Road/Faulconer Drive was not warranted under 2010 background conditions. With respect to the Faulconer Drive/Ramp from southbound US Route 29 intersection, a similar intersection improvement was noted under 2010 background conditions (i.e. a right turn taper). Given the fact that a right turn treatment was warranted under 2010 background conditions at the Faulconer Drive/Ramp from southbound US Route 29 intersection it is not recommended that the proposed Middle School be held responsible for this improvement. With respect to the westbound right turn taper at Old Ivy Road/Faulconer Drive, it is not recommended that the Middle School be responsible for the installation. Estimates indicate the proposed middle school will add approximately 20 vehicles to this specific movement; a volume of this magnitude in this setting should not require installation of an auxiliary taper. 34 STAB-Middle School TIA Appendix A Traffic Count Data STAB-Middle School 77A PAGE INTENTIONALLY BLANK STAB-Middle School 774 Table A-1 Turning Movement Counts St.Annes Belfield Development-Charlottesville,Virginia Start Date 1/24/2008 Start Time 7:00 AM Street Name Old Ivy Rd--Northbound Old Ivy Rd--Southbound Ivy Rd--Eastbound Ivy Rd--Westbound Start Time Left Thru Right Total Left Thru Right Total Left Thru Right Total Left Thru Right Total Total 8:00 AM 45 13 15 73 80 0 9 89 7 115 0 122 0 64 32 96 380 8:15 AM 5 1 1 7 41 0 3 44 14 201 0 215 0 88 39 127 393 8:30 AM 2 0 1 3 30 0 5 35 18 157 0 175 0 72 37 109 322 8:45 AM 3 0 0 3 54 0 3 57 9 173 0 182 0 66 30 96 338 Peak Hour Left _Thru Right Total Left Thru Right Total Left Thru Right Total Left Thru Right Total Total 8:00-9:00 55 14 17 86 205 0 20 225 - 48 646 0 694 0 290 138 _ 428 1433 PHF 0.31 " 0.27 0.28 0.29 0.64 • 0 0.56 0.63 0.67 0.80 0 0.81 0 0.82 0.88 0.84 0.91 Start Date 1/24/2008 Start Time 4.00 PM Street Name Old Ivy Rd--Northbound Old Ivy Rd--Southbound Ivy Rd--Eastbound I Rd--Westbound Start Time Left Thru Right Total Left Thru Right Total Left Thru Right Total Left Thru Right Total Total 3.30 PM 71 18 16 105 55 0 11 66 9 98 0 107 0 155 66 221 499 345 PM 20 4 5 29 70 0 15 85 5 149 0 154 0 188 79 • 267 535 4.00 PM 18 6 0 24 40 0 10 50 8 115 0 123 0 158 64 • 222 419 4.15 PM 4 3 2 9 39 0 13 52 5 137 0 142 0 152 56 208 411 Peak Hour Left Thru Right Total Left Thru Right Total Left Thru Right Total Left Thru Right Total Total 3.30-4.30 113 31 23 167 204 0 49 253 27 • 499 0 526 0 653 265 918 1864 PHF 0.40 0.43 0.36 0.40 0.73 0 0.82 0.74 0.75 • 0.84 0 0.85 0 0 87 0.84 0.86 0.87 Table A-2 Turning Movement Counts St.Annes Belfield Development-Charlottesville,Virginia Start Date 1/23/2008 Start Time 8:00 AM Street Name Canterbury Rd--Northbound Canterbury--Southbound Ivy Rd--Eastbound I Rd--Westbound Start Time Left Thru Right Total Left Thru Right Total Left Thru Right Total Left Thru Right Total Total 8:00 AM 5 5 1 11 22 5 119 146 106 179 4 289 2 111 64 _ 177 623 8:15 AM 7 1 10 18 12 6 115 133 102 161 3 266 3 120 48 171 588 8:30 AM 4 8 12 24 12 1 114 127 98 155 0 253 2 127 26 • 155 559 8:45 AM 4 10 7 ' 21 10 3 108 121 124 ▪ 159 0 283 2 119 31 152 577 Peak Hour - Left Thru Right Total Left Thru Right .
