(EPR) for Collins Engineering (Collins) to document the traffic impacts of the Redfields Phase 5 residential development. The proposed development is located just south of I- 64 (between Exit 118 and Exit 120), off of Sunset Avenue Ext. As proposed, the site includes 39 single family homes and 87 townhomes. The site is proposed as an additional phase of the current residential development served by Redfields Road; therefore, Redfields Road will provide access to this new phase as well. Figure 1 shows the site location and a vicinity map. The purpose of this traffic study is to evaluate traffic distribution and potential traffic impacts at three adjacent intersections along Sunset Avenue (Mountainwood Road, Redfields Road and Country Green Road) near the proposed development. 2.0 BACKGROUND The proposed development is located just south of I -64, off of Sunset Avenue, as part of the existing residential community served by Redfields Road. Sunset Avenue, Mountainwood Road, Redfields Road and Country Green Road are all two lane roads serving primarily residential uses. All three of the study intersections are "T" intersections. At Mountainwood Road and at Redfields Road, the side street is controlled by a STOP sign. The Sunset Avenue and Country Green intersection is All Way STOP controlled. Figure 1 is a vicinity map of the project area. A site plan (from Collins) is provided in Appendix A. Traffic Volumes Peak hour turning movement counts were conducted at the three study intersections on Wednesday, June 1, 2011 and Thursday, June 2, 2011. The counts were performed during the AM peak period (7:00 AM — 9:00 AM) and during the PM peak period (4:OOPM — 6:00 PM). The existing peak hour volumes are illustrated in Figure 2. The turning movement count data sheets are provided in Appendix B. It is important to note that the counts were performed after immediately after the end of the spring semester, thus the counts might be slightly lower than would have been with the University in session. The larger of the peak hours summed up to 399 vph, which would translate to 4,433 vpd assuming a "k" factor of .09, or 3990 assuming a "k" factor of .1. The VDOT traffic count database indicates that the 2009 ADT for Sunset Avenue is 4,600 vpd (no "k" factor listed). By comparison, the project TMCs may be between 4% and 13% lower than would have been with the University in session. Also worth noting is that the JPA bridge is out of service, therefore the distribution of traffic could have been skewed away from Old Lynchburg Road (into the City) with more traffic traveling to and from 5` Street Extended. 3 REDFIELDS PHASE 5 R IR TR AFFIC IMPACT S TUDY 5.1`.r 1 „s"..' . ontar O ' yr '' ' x F H y . •.+ f " ,„rr d,.. 11-, ,'Y., ilh * 'F„* y414°' a v' Y .- f., - dtu• - ' .

Given that there are no other new developments proposed in the study area, though there will be continued in -fill from an adjacent development, and there are no roadway connections that would generate background traffic growth, it can be assumed that any traffic volume growth would be very modest. As a conservatively high estimate, it was assumed that the background traffic would increase two percent per year to build year 2013. Figure 3 illustrates the resulting year 2013 no build traffic volumes in the study area. Proposed Site Trip Generation The trip generation potential of the proposed development was determined using data published in the Institute of Transportation Engineers' (ITE) Trip Generation Manual (8`" Edition). The resulting number of trips estimated to be generated by the proposed development is identified in Table 1.

The current directional distribution into and out of Redfields Road was utilized for the site ingress and egress trips (as all site trips will utilize Redfields Road). The current turning percentages at Mountainwood Road and Country Green Road were then also applied to the site trips. Figures 4 and 5 illustrate the resulting trip distribution percentages and site generated trips. Figure 6 illustrates the projected year 2013 build traffic volumes. 6 REDFIELDS PHASE 5 EPR TRAFFIC IMPACT STUDY 61) 16)t 132 45 20 (68) 1 7 (7) Mountainwood Tr 36 6 79) 8) i) 3) 67) 4 138 5) 6 1 Redfields 73) 165 43 42 121) 82) Site 127) 17) 281 24 t 19 (56) 1 L. 1 (21) Country Green Tr 65 3 N 215) 15) Figure 3D' No Build Year 2013 xxx(xxx) = am(pm) Peak Hour Volumes Peak Hour Volumes Not to Scale 7 REDFIELDS PHASE 5 R TRAFFIC IMPACT STUDY 9% (3 %) Mountainwood 4% a) 3 %) 9%E Redfields 7 %) 4% 0 93 %) 96% 97 %) Site 83 %) (11%) 89% 8%T 21% (20 %) Country Green 71% N 77 %) Figure 4D' Traffic Distribution % o xxx(xxx) = am(pm) Peak Hour Volumes Or Distribution Percentage Not to Scale 8 REDFIELDS PHASE 5 EPRTRAFFIC IMPACT STUDY 1 (1) Mountainwood 1) 1)6, 1 Redfields 1) 1 16) 27 8 27) Site 14) (2) 25 2 2 (6) Country Green 6 N 22) Figure 5t'14 Site Trips xxx(xxx) = am(pm) Peak Hour Volumes Peak Hour Volumes Not to Scale 9 REDFIELDS PHASE 5 E & ' R TRAFFIC IMPACT STUDY 61) 16)t 132 45 20 (68) i 8 (8) Mountainwood 1r 36 7 79) 9) 4) (67) 5 138 Redfields 6) 7 t 4 89) 192 51 42 148) 82) Site 141) (18) 306 26 t 21 (62) 1 (21) Country Green Tr 71 3 237) 15) Figure 61:1/ fei Build Year 2013 xxx(xxx) = am(pm) Peak Hour Volumes Peak Hour Volumes Not to Scale 10 Background + Site) 4.0 INTERSECTION CAPACITY ANALYSES The intersection capacity analyses were performed using Synchro (version 6) per the methodology documented in the Highway Capacity Manual (HCM 2000) (Transportation Research Board, Special Report #209, Revised 2000). The HCM based calculations are reported in this report. Capacity analyses are utilized to determine a Level of Service (LOS) for a given intersection operating under either signalized or unsignalized control. The LOS is based on estimated delay and range from LOS A, the best, to LOS F, the worst. In general LOS A and LOS B indicate little or no delay, LOS C indicates average delay, LOS D indicates delay is increasing and noticeable, LOS E indicates the limit of acceptable delay and LOS F is characteristic of over saturated conditions. The actual delays associated with these levels of service are identified in Table 2. TABLE 2 LOS and Delay Thresholds UNSIGNALIZED SIGNALIZED INT. DELAY INT.

All three of the study intersections are expected to operate satisfactorily with all movements operating at LOS A or LOS B during both peak hours given the build scenario. The build level of service is illustrated in Figure 7 on the following page. The HCM based intersection capacity analysis worksheets from Synchro are provided in the Appendix (existing in Appendix C and build 2013 in Appendix D). Also note that the traffic volumes for this study were collected after the University of Virginia had completed the spring semester. However, the capacity analysis results indicate that there is ample capacity remaining at the study intersections to account for any missing University related trips. Likewise, by inspection of the intersection /approach levels of service, if there is a shift in 11 the travel pattern resulting from re- opening of the JPA bridge, we would not expect to see a significant decrease in levels of service for any of the movements at the various intersection approaches. 5.0 SUMMARY Based on the analyses conducted, the proposed development will not have significant traffic impacts and no improvements are recommended. Regarding the distribution of new site trips across the immediate roadway network, as shown in Figure 4, it is anticipated that the site trips will replicate existing travel patterns and therefore the majority of the site trips will utilize Sunset Avenue out to Old Lynchburg Road (5 Street Extended) versus Mountainwood or Country Green. If the travel patterns shift with the reopening of the JPA bridge, since there is an abundance of available intersection capacity as demonstrated in the intersection analyses, we would not expect to see an overall adverse affect on any of the intersections considered in this study. 12 REDFIELDS PHASE 5 EPR TRAFFIC IMPACT STUDY A) A I_ A (A) Mountainwood A A) A) A 4- 4 Redfields A) B A A) Site A) A A (A) Country Green A N B) Figure 7t Build Year 2013 xxx(xxx) = am(pm) Peak Hour Volumes LOS Summary Not to Scale 13 Appendix A Site Plan iI' ni 1.' 4.. 1 v Z ZEIe.;. g7.i? 6) P. t, 1. 4.
