Purpose of Report and Study Objectives The purpose of this Traffic Impact Analysis is to evaluate the development of the Rancho Vista Village project from a traffic circulation standpoint. The proposed development is located within the City of Temecula. Study objectives include: (1) documentation of Existing traffic conditions in the vicinity of the site; (2) evaluation of Existing Plus Project conditions with and without the project; (3) evaluation of Project Completion (Year 2014) with and without the project; and (4) determination of on-site and off-site improvements and system management actions needed to achieve the City of Temecula level of service requirements. B. Site Location and Study Area The proposed project is located at the northeast corner of Mira Loma Drive at Rancho Vista Road, in the City of Temecula. The project site is currently vacant. Exhibit 1-1 illustrates the site location map and traffic analysis study area. The study area includes the following intersections: North-South Street East-West Street Ynez Road Rancho California Road Ynez Road Rancho Vista Road Mira Loma Drive (West) Rancho Vista Road Mira Loma Drive (East) Rancho Vista Road Margarita Road Rancho Vista Road 1-2 C. Development Project Description The proposed project would consist of 57 single family homes. Exhibit 1-2 illustrates the site plan. The proposed project will access to the adjoining roadway network via two (2) full access driveways on Mira Loma Drive. “B” Street will serve as the main entrance to the site, and “A” Street will serve as the secondary access point. A tract map for this site was previously approved for 62 single family homes. The revised tract will lessen the amount of homes to be built and the traffic impacts associated with the latest tract would also be less. 2-1 2.0 Area Conditions A. Study Area The study area includes the following intersections: North-South Street East-West Street Ynez Road Rancho California Road Ynez Road Rancho Vista Road Mira Loma Drive (West) Rancho Vista Road Mira Loma Drive (East) Rancho Vista Road Margarita Road Rancho Vista Road B. Existing Traffic Controls and Intersection Geometrics Exhibit 2-1 identifies the existing roadway conditions for the study area roadways. The number of through traffic lanes for existing roadways and the existing intersection controls are identified. C. Existing Traffic Volumes Existing AM and PM peak hour traffic volumes for the study area intersections are shown on Exhibit 2-2. These volumes are based upon manual AM and PM peak hour turning movement counts collected in June 2012 and January 2013. The traffic count worksheets are included in Appendix A. To account for potential increases in delay, as a result of school traffic at the study area intersections near the site, traffic counts obtained by LINSCOTT, LAW & GREENSPAN ENGINEERS were used for AM peak hour traffic conditions. 2-2 Existing Average Daily Traffic (ADT) volumes for roadway segments within the study area have been provided by the City of Temecula and are based on counts taken in Year 2011. D. Existing Level of Service Existing intersection level of service calculations are shown in Table 2-1 and are based on manual AM and PM peak hour turning movement counts. Definitions of the Highway Capacity Manual’s Level of Service (LOS) standards are included in Appendix B. The City of Temecula requires a Level of Service D or better for all intersections. Under Existing traffic conditions, all study area intersections are currently operating at LOS D or better during the peak hours, with the exception of Ynez Road (NS) at Rancho California Road (EW). This intersection is currently operating at LOS E during the PM peak hour. HCM calculation worksheets for Existing conditions are provided in Appendix C. E.

Project Traffic Conditions 1. Trip Generation Trip generation represents the amount of traffic that is attracted and produced by a development. The trip generation rates are based upon data collected by the Institute of Transportation Engineers (ITE) Trip Generation, 9th Edition. This publication provides a comprehensive evaluation of trip generation rates for a variety of land uses. Both daily and peak hour trip generation rates for the uses analyzed in this study are shown in Table 3-1. The traffic generation for the proposed project is based upon the specific land uses that have been planned for the development. The project site is currently zoned for medium density residential land use, as approved under the existing General Plan. The approved land use for this site would consist of 62 single family dwelling units. The proposed project is seeking to reduce the number of units due to site’s topography. The proposed project would now consist of 57 single family dwelling units. The project site is currently vacant and no trip credit for an existing land use was taken. Both daily and peak hour trip generation for the previously approved land use and the proposed development are shown in Table 3-2. The previously approved land use would generate approximately 590 total trip-ends per day, with 47 total vehicle trips during the AM peak hour and 62 total trip ends per day during the PM peak hour. The proposed development is projected to generate approximately 543 total trip-ends per day, with 43 total vehicles per hour during the AM peak hour and 57 total vehicles per hour during the PM peak hour. 3-2 The net trip change as a result of the proposed project would be approximately 47 less trip-ends per day, with 4 less vehicle trips during the AM peak hour and 5 less trips per day during the PM peak hour. 2. Trip Distribution and Assignment Trip distribution represents the directional orientation of traffic to and from the project site. Trip distribution is heavily influenced by the geographical location of the site, the location of retail, employment, recreational opportunities, and the proximity to the regional freeway system. The directional orientation of traffic was determined by evaluating existing and proposed land uses and highways within the community. Trip distribution patterns for this study have been based upon near-term and general plan buildout conditions, and are based upon those highway facilities that are either in place or will be contemplated over the next few years. The trip distribution patterns for the project are graphically depicted on Exhibit 3-1. The assignment of traffic from the site to the adjoining roadway system has been based upon the site's trip generation, trip distribution, and proposed arterial highway and local street systems that this traffic study assumes would be in place by the time of initial occupancy of the site. 3. Modal Split Modal split denotes the proportion of traffic generated by a project that would use any of the transportation modes, namely buses, cars, bicycles, motorcycles, trains, carpools, etc. The traffic reducing potential of public transit and other modes is significant. However, the traffic projections in this study are conservative in that public transit and alternative transportation may be able to reduce the traffic volumes. Thus no modal split reduction is applied to the projections. With the 3-3 implementation of transit service and provision of alternative transportation ideas and incentives, the automobile traffic demand can be reduced significantly. 4. Project Peak Hour Traffic Volumes Project AM and PM peak hour intersection turning movement volumes and average daily traffic are shown on Exhibit 3-2. 5. Existing Plus Project Peak Hour Traffic Volumes Existing Plus Project AM and PM peak hour intersection turning movement volumes and average daily traffic includes existing traffic volumes, counted in June 2012, plus project traffic volumes. Existing Plus Project traffic volumes are shown in Exhibit 3-3. B. Background Traffic 1. Method of Projection To assess Project Completion (Year 2014) traffic conditions, project traffic is combined with existing traffic, area-wide growth and cumulative projects’ traffic. Project Completion Year is expected to be in Year 2014. A general plan buildout analysis has not been performed for this project since the latest proposed development would conform to the current General Plan zoning allowance of medium density residential. 2. Cumulative Projects Traffic Table 3-3 lists the proposed land uses for the nearby cumulative projects for Project Completion (Year 2014) With Cumulative Projects traffic conditions, known at the time this study was prepared. Cumulative projects have been obtained from 3-4 the City of Temecula Staff. Cumulative impacts analyzed in this traffic impact study were conservatively assessed. Some of the cumulative projects may be downsized or may not be approved, and some approved projects may not be developed. The cumulative analyses set forth below are conservative and may result in greater impacts than actually anticipated. Developments that have been approved or are being processed concurrently in the study area, include the projects illustrated on Exhibit 3-4. The cumulative development trip distributions are shown on Appendix D. Table 3-3 shows the peak hour and daily vehicle trips generated by the Cumulative Projects being processed concurrently in the study area. Cumulative Projects AM and PM peak hour intersection turning movement volumes and average daily traffic are shown on Exhibit 3-5. 3. Background Traffic Growth Rate To account for area-wide growth on the roadways, future traffic volumes have been calculated based on a two percent (2%) annual growth rate of existing traffic volumes over a two-year period for counts taken in Year 2012. Future average daily traffic volumes have been calculated based on a two percent (2%) annual growth rate of existing average daily traffic over a three-year period for counts taken in Year 2011. The City of Temecula provided the area-wide growth rate. C. Project Completion (Year 2014) Without Project Traffic Volumes Project Completion (Year 2014) without project traffic conditions includes existing traffic volumes on surrounding roadways, cumulative project traffic, and area-wide growth. The AM and PM peak hour intersection turning movement volumes and average daily traffic are shown on Exhibit 3-6 for Project Completion (Year 2014) Without Project traffic conditions. 3-5 D. Project Completion (Year 2014) With Project Traffic Volumes Project Completion (Year 2014) With Project traffic conditions includes existing traffic volumes on surrounding roadways, project traffic, area-wide growth and cumulative projects. Project Completion (Year 2014) With Project AM and PM peak hour intersection turning movement volumes and average daily traffic are shown on Exhibit 3-7. 3-6 THIS PAGE INTENTIONALLY LEFT BLANK InOutTotalInOutTotal Medium Density (Approved General Plan Land Use) Single Family Detached 210DU0.190.560.750.630.371.009.52 1 Source: Institute of Transportation Engineers (ITE) Trip Generation manual, 9th Edition, 2012. 2 DU =Dwelling Units TABLE 3-1 Trip Generation Rates1 Zoning PM Peak HourITE Trip Code DailyLand Use Units2 AM j:\rktables\RK10063TB.xls JN:0518-2012-01 InOutTotalInOutTotal Medium Density (Approved General Plan Land Use) Single Family Detached 62DU123547392362590 Medium Density (Proposed General Plan Land Use) Single Family Detached 57DU113243362157543 -1-3-4-3-2-5-47 1 DU = Dwelling Unit Project Trip Generation TABLE 3-2 Zoning Net Decrease as a Result of Proposed Land Use Quantity Units1 Peak Hour Land UseDailyAMPM j:\rktables\RK10063TB.xls JN:0518-2012-01 InOutInOut Assisted Living25499Beds1251514271 1251514271 Single Family Residential21016DU39106153 39106153 Single Family Residential21015DU38106144 38106144 Hotel310142RM483144401,160 Restaurant9326.000TSF36333927763 846483671,923 Condo/Townhomes23023DU2984134 2984134 Hospital230566.160TSF3742602723749,342 3742602723749,342 Hotel31064RM22142018523 22142018523 Condo/Townhomes230210DU157874361,220 157874361,220 51544749252513,710 1 Source: City Temecula Planning Department 2 TSF = Thousand Square Feet DU = Dwelling Units RM = Rooms 7 Comfort Suites Hotel Subtotal 8 Rancho Highlands Maravilla Subtotal 5 Tierra Vista Condo Buildout Subtotal 6Temecula Hospital Subtotal Simms TTM/GPA/ZC Subtotal 4 Temecula Heritage Hotel Subtotal Total Trip Generation for All Cumulative Projects DailyUnits2 1 Highgate Senior Living Subtotal 2 TTM No. 30434 (Paine TTM)Subtotal 3 TABLE 3-3 Cumulative Projects Trip Generation1 ZoneProject Peak Hour AMPM Land UseITEQuantity j:\rktables\RK10063TB.xls JN:0518-2012-01 4-1 4.0 Traffic Analysis A. Capacity and Level of Service Improvement Analysis 1. Level of Service for Existing Plus Project Conditions Intersection levels of service for the Existing Plus Project conditions are shown in Table 4-1. For Existing Plus Project traffic conditions, all study area intersections are projected to operate at LOS D or better during the peak hours with the exception of the following intersection, which will continue to operate at an LOS “E”: North-South Street East-West Street Ynez Road Rancho California Road This intersection will continue to operate at LOS “E” under Existing Plus Project traffic conditions. An increase in overall intersection delay of 0.6 seconds is expected to occur as a result of the project. Since the increase in delay is below the City’s 2.0 second threshold, the project’s impact at this intersection is considered insignificant. HCM calculation worksheets for Existing Plus Project conditions are provided in Appendix E. 2. Level of Service for Project Completion (Year 2014) Without Project Conditions Intersection levels of service for the Project Completion (Year 2014) Without Project conditions are shown in Table 4-2. For Project Completion (Year 2014) Without Project traffic conditions, all study area intersections are projected to operate at 4-2 LOS D or better during the peak hours, with the exception of the following intersections, which are expected to operate at Los E. North-South Street East-West Street Ynez Road Rancho California Road Ynez Road Rancho Vista Road HCM calculation worksheets for Project Completion (Year 2014) Without Project conditions are provided in Appendix F. 3. Level of Service for Project Completion (Year 2014) With Project Conditions Intersection levels of service for Project Completion (Year 2014) With Project conditions are shown in Table 4-3. For Project Completion (Year 2014) With Project traffic conditions, all study area intersections are projected to operate at LOS D or better during the peak hours with the exception of the following intersections, which will continue to operate at LOS “E”: North-South Street East-West Street Ynez Road Rancho California Road Ynez Road Rancho Vista Road These intersections will continue to operate at LOS “E” under Opening Year (2014) with Project traffic conditions. An increase in overall intersection delay of 0.9 seconds and 0.7 seconds is expected to occur at Ynez Road at Rancho California Road and Ynez Road at Rancho Vista Road, respectively, as a result of the project. Since the increase in delay is below the City’s 2.0 second threshold, the project’s impact at this intersection is considered insignificant. 4-3 HCM calculation worksheets for Project Completion (Year 2014) With Project conditions are provided in Appendix G. 4. Traffic Signal Warrants Peak hour traffic signal warrants have been analyzed at the following unsignalized study area intersection: North-South Street East-West Street Mira Loma Drive Rancho Vista Road Traffic signal warrants have been performed at the above study area intersection for all study scenario conditions. The intersection is projected to not satisfy peak hour traffic signal warrants. A traffic signal is not required in order to improve level of service operations at this intersection. The traffic signal warrant analysis worksheets are included in Appendix H. 4-4 THIS PAGE INTENTIONALLY LEFT BLANK L T R L T R L T R L T R A M P M A M P M • R a n c h o C a l i f o r n i a R o a d ( E W ) T S 2 . 0 2 . 0 1 . 0 2 . 0 2 . 0 2 . 0 > 2 . 0 3 . 0 1 . 0 > 1 . 0 3 . 0 1 . 0 3 8 . 3 6 5 . 8 D E 4 • R a n c h o V i s t a R o a d ( E W ) T S 0 . 0 1 . 0 1 . 0 1 . 0 2 . 0 0 . 0 0 . 0 0 . 0 0 . 0 1 . 0 0 . 0 1 . 0 > 4 9 . 4 3 4 . 3 D C • R a n c h o V i s t a R o a d ( E W ) C S S 0 . 0 0 . 0 0 . 0 1 . 0 0 . 0 1 . 0 1 . 0 1 . 0 0 . 0 0 . 0 1 . 0 1 . 0 1 7 . 2 1 2 . 5 C B • R a n c h o V i s t a R o a d ( E W ) T S 0 . 0 1 ! 0 . 0 0 . 5 0 . 5 1 . 0 1 . 0 1 . 5 0 . 5 1 . 0 1 . 5 0 . 5 2 2 . 0 2 1 . 7 C C • R a n c h o V i s t a R o a d ( E W ) T S 1 . 0 2 . 0 1 . 0 1 . 0 2 . 0 1 . 0 1 . 0 1 . 5 0 . 5 1 . 0 1 . 0 1 . 0 2 7 . 9 3 3 . 1 C C 1 L = L e f t ; T = T h r o u g h ; R = R i g h t ; > = R i g h t T u r n O v e r l a p ; > > = F r e e R i g h t T u r n ; Bo l d = I m p r o v e m e n t ! = I n d i c a t e s g e n e r a l p u r p o s e l a n e 2 3 TS = T r a f f i c S i g n a l CS S = C r o s s S t r e e t S t o p 4 Tr a f f i c Co n t r o l 3 In t e r s e c t i o n Yn e z R o a d ( N S ) a t An a l y s i s S o f t w a r e : S y n c h r o 7 .

Intersection Analysis Summary A summary of the Existing Conditions level of service analysis for each condition is included in Table 5-1. Under existing traffic conditions, all study area intersections are currently operating at acceptable conditions during the peak hours, with the exception of the following intersection which is currently operating at an LOS “E”: North-South Street East-West Street Ynez Road Rancho California Road The proposed project will consist of 57 single family units and it is projected to generate approximately 533 trip-ends per day, with 43 vehicles per hour during the AM peak hour and 57 vehicles per hour during the PM peak hour. Intersection levels of service for Project Completion (Year 2014) With Project Conditions are shown in Table 5-2. Traffic conditions include existing traffic volumes on surrounding roadways, area wide growth and cumulative projects traffic. All study area intersections are projected to operate at an acceptable level of service during the peak hours, except for the following intersections, which are projected to operate at an LOS “E”: North-South Street East-West Street Ynez Road Rancho California Road Ynez Road Rancho Vista Road 5-2 No mitigation is required for Project Completion (Year 2014) with project conditions, as the project does not increase the overall intersection delay by more than two (2) seconds. B. Proposed Mitigation Measures No mitigation measures are required for the proposed project. A summary of the change in level of service with the addition of the project is provided in Tables 5-1 and 5-2. The project is not expected to have a significant impact at any of the study area intersections. C. Circulation Recommendations 1. On-Site I. Construct the on-site circulation system per the detailed site plan. II. Install stop signs, stop bars, and stop legends at all project access points. On-site circulation recommendations are shown on Exhibit 5-2. 2. Area-Wide I. A traffic signal at the intersection of Mira Loma Drive at Rancho Vista Road is not required from a level of service standpoint. Area-wide recommendations are summarized on Exhibit 5-2. 5-3 D. Intersection Sight Distance, Safety and Operational Improvements The City of Temecula utilizes the sight distance design standards identified in the California Highway Design Manual to determine intersection sight distance. The required stopping sight distance for a private road or driveway is 200 feet on roadways with a speed of 30 miles per hour. Mira Loma Drive is classified as a local street and therefore has a design speed of 30 miles per hour, as shown on the City of Temecula Roadway Design Requirements Standard Plan No. 113. This sight distance standard is also consistent with design standards identified in the County of Riverside’s Standard Drawing No. 821. A copy of the reference material is available in Appendix I. Exhibit 5-1 shows the intersection sight distance analysis at the intersection of the project driveway at Mira Loma Drive. The required stopping sight distance for this driveway is 200 feet, based on a design speed of 30 miles per hour. This is considered conservative, as the actual posted speed limit on Mira Loma Drive is 25 miles per hour. Per the latest grading plans, adequate sight distance would be obtainable at both project driveways. The sight distance analysis takes into consideration both vertical and horizontal changes in the roadway, which may affect driver vision. The vertical change in elevation on Mira Loma Drive is approximately 25 feet over a span of 200 feet from the project access locations. The slope of Mira Loma Drive is downward, south to north, from Rancho Vista Road toward the project access. This angle of slope would allow for adequate sight distance. The project accesses are located on the inside of a horizontal curve on Mira Loma Drive which limits the amount of sight distance for a driver. However, provided a limited use area is established, adequate sight distance is obtainable. Per the sight distance standards, a limited use area should be established and maintained to provide a clear line of sight for vehicles negotiating an intersection. No 5-4 trees, walls, or any objects over 30 inches high shall be allowed in the limited use area. Also, on-street parking should be restricted for approximately 130 feet south of access “B” and 90 feet north of access “A”, within the limited use areas of each intersection. No parking should be allowed between the project access intersections on Mira Loma Drive As is the case for any roadway design, the City of Temecula should periodically review traffic operations in the vicinity of the site once the project is constructed to assure that the traffic operations are satisfactory. E. Regional Funding Mechanisms Participate in the City’s adopted TUMF (Transportation Uniform Mitigation Fee) program and pay development fees as required by the City of Temecula. F. Conclusions Based upon this review, the proposed Rancho Vista Village project can be accommodated in the City of Temecula.
