Coletara Development ii Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 Executive Summary This study has been completed to assess the traffic impacts associated with the development of 300 condominium apartment units and a 105 unit retirement residence at the intersection of Starwood Drive/Watson Parkway North in the City of Guelph. Some of the ground floor units along Starwood Drive may also accommodate commercial uses. This study has been prepared to support an application for a Zoning By-law Amendment for the proposed development. Based on the analysis completed, the main conclusions and recommendations of this study are as follows: The proposed development is forecast to generate total traffic (two-way) of 163 vph in the a.m. peak hour, 228 vph in the p.m. peak hour and 238 vph in the Saturday peak hour. A growth rate of 2.0% per annum (compounded) has been assumed for background traffic growth in the study area, exclusive of the traffic from the condominium development or from other external developments in the immediate study area. These external developments are forecast generate total traffic (net, two-way) of 778 vph in the a.m. peak hour, 1230 vph in the p.m. peak hour and 1357 vph in the Saturday peak hour. A time horizon of 2019 has been considered for future traffic impacts in this study. Forecast left turn volumes at the site accesses, in the p.m. peak hour and Saturday peak hour, are forecast to meet the Ministry of Transportation guidelines for the consideration of left turn lanes at these locations. However, the overall traffic volumes forecast on Watson Parkway, along with its four lane cross section, will provide sufficient operational flexibility to negate the need for an exclusive left turn lane at the site access. For the Starwood Drive accesses, the urban design concept for the corridor restricts traffic operations to a low speed urban condition. Therefore, given the low turning volumes at the site accesses, the corridor is expected to function adequately without the introduction of exclusive left turn lanes in this area. The Synchro analysis also shows that all accesses will operate acceptably, with minimal delays or queuing for the ingress movements. 300033023.0000 033023_TIS.docx
Coletara Development iii Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 All intersections and accesses are forecast to operate acceptably through horizon year 2019 under Total Traffic conditions, with the exception of the following: Northwest bound through movement at the intersection of Watson Parkway North /York Road, that is forecast to have long delays. Adjustment of the signal timing is recommended to mitigate this deficiency. Southbound left/through/right movement at the intersection of Starwood Drive/11 Starwood Access/North (West) Access, that is forecast to have long delays. However, sufficient gaps are available to accommodate this movement, with no improvements being required. Small deficiencies are forecast in the queuing storage at the Starwood Drive/ Watson Parkway North intersection (northbound left turn lane), at the Watson Parkway North/York Road intersection (northeast bound left turn lane), and at the Starwood Drive/Grange Road intersection (westbound left turn lane). However, these deficiencies can be mitigated through an adjustment of the signal timing at these locations. The eastbound left turn movement at the intersection of Starwood Drive/Watson Parkway North is forecast to have long delays under Total Traffic Conditions in 2014, assuming stop controls on Starwood Drive (i.e., unsignalized). However, sufficient gaps are available to accommodate this movement in the short term. While it is forecast that the volume warrants for signalization at this intersection may not be met under this scenario, it is expected that these warrants will be met in the following five year horizon period. It is expected that the City will continue to monitor traffic at this location, with signals being implemented once the volume warrants have been met. Sufficient sight distances are available at the accesses to the proposed development. Sufficient spacing is provided between the proposed driveways and corner clearances meet typical requirements for full-move accesses. Under unsignalized conditions, a visibility triangle of approximately 2.5 metres (Starwood Drive frontage) by 4.6 metres (Watson Parkway North frontage) may be provided at the southwest quadrant of the intersection of Starwood Drive/Watson Parkway North. Assuming that signals will be installed at this intersection, there is no theoretical requirement for a visibility triangle at this location. However, if such a triangle is ultimately requested by the City, we would suggest that the upper limit of its dimensions be based on stop control criteria, as noted above. Parking considerations for the proposed development have been reviewed in a separate letter report. A maximum parking demand of 412 spaces on-site has been identified to accommodate this development. 300033023.0000 033023_TIS.docx

Coletara Development 1 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 1.0 Study Purpose and Background Information 1.1 Study Purpose R. J. Burnside & Associates Limited (Burnside) was retained by Coletara Development (Starwood Watson Holdings Inc.), to prepare a Traffic Impact Study (TIS) to support the development of a residential condominium apartment project in the City of Guelph. The purpose of this TIS is to assess the traffic impacts/mitigation requirements associated with the proposed development, in accordance with the City s Traffic Impact Study Guidelines (July 2011). 1.2 Background Information The following reports were reviewed in the preparation of this TIS: Guelph Watson 5-3 Inc., Traffic Impact Study; dated November 2011; prepared by Exp. Services Inc.; Stockford Road Elementary School, Traffic Impact Study; dated July 2012; prepared by Pardigm Transportation Solutions Ltd.; 115 Watson Parkway North, Traffic Impact Study; dated March 2009; prepared by LEA Consulting Ltd.; Official Plan 2001 - City of Guelph; December 2012 Consolidation; Zoning Bylaw (1995) 14864 City of Guelph; Guelph-Wellington Transportation Study; dated July 2005; prepared by TSH Engineers, Paradigm Transportation Solutions, GSP Group; and Urban Design Action Plan; dated May 2009; prepared by Urban Strategies Inc. 300033023.0000 033023_TIS.docx
Coletara Development 2 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 2.0 Site / Development Description For the purposes of this TIS, Watson Parkway North is considered to run north-south and Starwood Drive is considered to run east-west. The development site is approximately 2.65 hectares in area and is located at the southwest corner of the intersection of Watson Parkway North/Starwood Drive (see Figure A1, Appendix A). The preliminary site plan concept for the development is shown on Figure A2 (Appendix A), and described as follows: Southern section of the site 150 condominium apartment units (two buildings) with a proposed full-move access onto Watson Parkway North. The proposed access is located about 130 metres to the south of the intersection of Starwood Drive/Watson Parkway North (centre to centre). Northern section of the site 150 condominium apartment units (two buildings) with ground floor commercial uses (live/work, assumed 5000 sq. ft.) in one of these buildings, plus 105 unit retirement residence with ground floor commercial uses (assumed 5000 sq. ft. general commercial), with two full-move accesses onto Starwood Drive. The north (east) access is located about 80 metres west of the intersection of Starwood Drive/Watson Parkway North (centre to centre), while the north (west) access is located about 150 metres to the west of the intersection of Starwood Drive/Watson Parkway North (centre to centre). It is noted that the final form of development is subject to change, as the project proceeds through the site plan approval process. However, the assumptions made in this study are considered to be conservative, and therefore there is flexibility in accommodating such changes, without significantly impacting the conclusions and recommendations of this report. The area surrounding the intersection of Watson Parkway North/Starwood Drive is identified in the City s Official Plan (Schedule 1B) as being a Community Mixed Use Node, and zoned as B.1 Industrial in the City s Zoning Bylaw. The development requires an application for a Zoning By-law Amendment (ZBA) to implement the residential uses. The development site is presently vacant and is located in a developing area. In the immediate area, a public library has been constructed (northwest corner of Watson Parkway North/Starwood Drive), while the other lands in the area are vacant, but planned for development (residential and commercial). 300033023.0000 033023_TIS.docx
Coletara Development 3 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 3.0 Existing Roads Based on discussions with City staff the scope for this study was confirmed to include traffic operations at the intersections noted below. The functional classifications and posted speeds are also noted below for the intersecting streets, as follows: Watson Parkway North/Starwood Drive Watson Parkway North is a four lane arterial road with a posted speed of 60 km/h, with an existing right-of-way (ROW) of 27 metres and a proposed ROW of 30 metres (Figure A3, Appendix A). Starwood Drive is a two lane arterial road (with parking lanes), with a posted speed of 50 km/h and a ROW of 30 metres. It is our understanding that the City intends to redevelop Starwood Drive in this area to include 2 travel lanes, 2 parking lanes and 2 bike lanes (Figure A4, Appendix A). Watson Parkway North/Grange Road Watson Parkway North is a four lane arterial road with a posted speed of 50 km/h. Grange Road is a two lane arterial road with a posted speed of 50 km/h Watson Parkway/York Road To the north of York Road, Watson Parkway North is a four lane arterial road with a posted speed of 60 km/h. To the south of York Road, Watson Parkway South is two lane arterial road with a posted speed of 60 km/h. Starwood Drive/Grange Road Starwood Drive is a two lane arterial road with a posted speed of 50 km/h, however its width is sufficient to accommodate additional parking lanes, as noted above. Grange Road is a two lane arterial road with a posted speed of 50 km/h. All roads are under the jurisdiction of the City of Guelph. The Official Plan identifies Watson Parkway North, Grange Road and York Road as having ultimate right-of-way widths of 30 metres. It is also noted that improvements are anticipated at the intersections of Watson Parkway North/Starwood Drive and at Watson Parkway North/ Grange Road. The lane configurations and traffic controls at the intersections in the study area are shown on Figure A6 (Appendix A). The intersections at Watson Parkway North/Grange Road, Watson Parkway North/York Road and Grange Road/Starwood Drive are presently signalized, while the intersection of Watson Parkway North/Starwood Drive is under stop sign control on the Starwood Drive approach. 300033023.0000 033023_TIS.docx
Coletara Development 4 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 4.0 Traffic Forecasts 4.1 Analysis Period This study has considered existing conditions (2013), as well as a five year horizon period after initial development in 2014 (year 2019). It is acknowledged that occupancies of the development may not occur until 2015 or 2016, however, the timeframe considered in this report is sufficient to assess traffic impacts, considering the overall background traffic (i.e., growth rate and other developments) that has been included in the analysis. The proposed development is mixed use (residential plus ground floor commercial in some of the buildings). Therefore, the periods considered for analysis include the a.m. peak hour and p.m. peak hour of the adjacent streets, as well the peak hour period on a Saturday. The proposed analysis periods have been confirmed with City staff. 4.2 Background Traffic Demand and Modal Split Background turning movement counts were obtained from the following sources, for the intersections being studied: Peak period traffic counts taken on Saturday March 2, 2013 at all of the four intersections being studied. Counts were taken by our sub-consultant, Ontario Traffic Inc. Peak period traffic counts taken in the a.m. and p.m. peak periods on a weekday (May 17, 2012) at the intersection of Watson Parkway North/Starwood Drive. Traffic counts were provided by the City. Peak period traffic counts taken in the a.m. and p.m. peak periods on a weekday (2012) at the intersection of Starwood Drive/Grange Road. These traffic counts were obtained from an earlier TIS (Stockford Road Elementary School, Traffic Impact Study, Paradigm Transportation Solutions Inc.). Peak period traffic counts taken in the a.m. and p.m. peak periods on a weekday (2010) at the intersections of Watson Parkway North/Grange Road and Watson Parkway North/York Road. This data was updated by balancing the counts with the more recent counts taken at the Starwood Drive intersection. Select traffic count data is included in Appendix B. For the purposes of this study a background traffic growth rate of 2.0% per annum (compounded) has been applied to the traffic counts, as suggested by City staff. This is to account for traffic growth from the broader study area, while traffic generated from 300033023.0000 033023_TIS.docx
Coletara Development 5 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 developments in the immediate study area have been considered as additional to this background growth. The turning movement counts have been updated to current conditions (2013) using the 2.0% per annum growth rate. The resulting existing background traffic turning movement volumes are shown on Figure A7 (Appendix A). As noted above, the traffic generation from the developments in the immediate study area, have been added to the background traffic for the 2019 time horizon. This assumes that these developments will be completed within this time period. The City has identified the following developments in the study area that are to be included in the traffic forecasts: Metrus Development (11 Starwood Drive) 201 town houses located at the northwest corner of Watson Parkway North/Starwood Drive. We have also included 1115 sq.m. of retail development on these lands, as per earlier TIS reports. Cityview Ridge Development 101 single detached houses, 40 semi-detached houses, 64 townhouses, 54 apartment units. This development is proposed to the south of the site, with access from Cityview Drive. 115 Fleming Road 63 townhouses. This development is proposed to the north of the Metrus Development, with access from Fleming Road. 115 Watson Parkway North 10,000 sq. m. of food store and 2,000 sq. m. of retail. This development is located on the east side of Watson Parkway North, opposite to the site. Watson 5-3 Inc. 90 apartment units. This development is located at the intersection of Watson Parkway North and Watson Road North. The locations of these additional external developments are shown on the map provided by the City (Figure A5, Appendix A). The future lane configurations and traffic controls at the intersections in the study area are shown on Figure A8 (Appendix A). In addition to the above, the traffic from a proposed new elementary school (Stockford Road Elementary School) has also been included in the traffic forecasts. The new school is located to the west of the site, with access onto Lee Street. The traffic forecasts from the above noted developments have been based on previous TIS reports, that where available. Where TIS reports were not available, the traffic forecasts have been made based on trip generation rates provided in the Trip Generation Manual, 9 th Edition (Institute of Transportation Engineers). The traffic forecast for external developments is summarized in the following table: 300033023.0000 033023_TIS.docx

Coletara Development 7 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 vph in the Saturday peak hour. However, given the locations of these developments, only some of these trips will travel through the study area. The assumed distribution of the trips from these external developments has been based on the previous TIS work for those developments. The forecast of the traffic from the external developments, travelling through the study area, is shown on Figure A9 (Appendix A). The combined background traffic, growth in background traffic and external development traffic is shown on Figure A10 (Appendix A). There are no planned improvements to the transportation system that may impact traffic in the study area, within the horizon periods considered. While it is expected that improvements to the transit system, as well as to the cyclist/pedestrian infrastructure within the City, will continue to shift transportation modes away from private cars in the longer term, no allowance is made in this study to reflect such reductions in demand, considering the short term being considered. 4.3 Site Generated Traffic Volumes Site generated traffic volumes have been estimated based on the trip rate information contained in the Institute of Transportation Engineers (ITE) Trip Generation Manual (9th Edition). As noted previously it is conservatively assumed that there will not be any shifting of transportation modes away from car travel in the short term, and therefore the ITE trip rates are considered to be conservative. For the purposes of this report it has been assumed that a limited amount of commercial space will be included on the ground floors of the buildings on Starwood Drive (assumed 5,000 sq. ft. of general commercial uses in the retirement residence and 5,000 sq. ft. of live/work commercial uses in the apartment that is located immediately west of the retirement residence). The trip generation for this use is based on ITE Code 826 (Specialty Retail Centre). This commercial space will largely be focused on neighbourhood needs. Since this retail space would not likely be open during the a.m. peak period, no traffic is assigned during that time for this use. For the p.m. peak period and the Saturday peak period it is assumed that 50% of this retail space services the immediate area and that 50% generates traffic to/from the road network. The trip generation for the condominium apartments has been based on ITE Code 230 (Condominium Townhouse). The trip generation for the retirement home units has been based on ITE Code 252 (Senior Adult Living Attached). 300033023.0000 033023_TIS.docx
Coletara Development 9 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 4.4 Total Traffic Forecasts The development traffic is added to the background traffic plus growth in background traffic (including external developments) to obtain the total traffic volumes at the intersections in the study area and at the site accesses. The forecast total traffic volumes for horizon year 2019 are shown in Figure A12 (Appendix A). 300033023.0000 033023_TIS.docx
Coletara Development 10 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 5.0 Traffic Impact Analysis 5.1 Analysis Criteria and Approach The traffic operations at the subject intersections/accesses within the study area have been assessed based on the following criteria: Turning lane considerations (unsignalized intersections), based on Ministry of Transportation (MTO) warrant graphs and criteria. Levels of Service (LOS) and volume/capacity ratios for overall intersections/accesses or for individual critical turning movements, based on criteria in the Highway Capacity Manual, analyzed using Synchro Software. The analysis of the signalized intersections utilizes the existing traffic signal timing, as provided by the City. Queuing constraints were also confirmed for the intersections/accesses. For signalized intersections the critical movements were identified where: v/c ratios for the overall intersection, or for the through movements or the shared through/turning movements increased to 0.85 or above; or v/c ratios for exclusive turning movements increased to 0.90 or above; or 95 th percentile queues for an individual turning movement are projected to exceed available lane storage. For unsignalized intersections the critical movements were identified where: Levels of Service (LOS), on individual movements, exceed LOS E, based on average delay per vehicle; or The estimated 95 th percentile queue length for an individual movement exceeds the available queue storage. The analysis has considered the a.m. and p.m. weekday peak hours of the traffic on the streets in the study area, including the following: existing traffic conditions (2013); future traffic conditions (2019) including background growth and external development; and future total traffic conditions (2019), including background traffic, as well as traffic from background growth, external development and site development. 300033023.0000 033023_TIS.docx
Coletara Development 11 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 5.2 Left Turn Lane Considerations (Unsignalized Intersections) The warrants for exclusive left turn lanes were considered at the unsignalized intersections/accesses within the study area. Left turn lane warrants have been assessed for horizon year 2019, based on the MTO warrant graphs, as shown in Appendix C. The results of the left turn lane warrant analysis, under Total Traffic Conditions, are summarized in the following table: Table 5.1 Left Turn Lane Warrants For Unsignalized Intersections/Access (Horizon Year 2019) Left Turn Intersection Direction Storage Left Turn Left Turn For Storage For Storage For Weekday Saturday Peak Weekday a.m. p.m. Peak Hour Peak Hour Hour (m) (m) East Access/ Watson Parkway Northbound Not required 15 15 North (East) Access/ Westbound Not required 25 15 Starwood Drive North (West) Eastbound Not required 15 15 Access/ Street 1 /Starwood Drive Westbound Not required 15 15 Based on the analysis, it is concluded that left turn volumes at the proposed accesses meet the MTO warrant guidelines, where a left turn lane may be considered, under p.m. peak hour and Saturday peak hour conditions (horizon year 2019). Since Watson Parkway is a four-lane facility, sufficient opportunity will exist to adequately accommodate the relatively low volume of left turn movements, without the need for an exclusive left turn lane. On Starwood Drive, the urban design concept for this corridor restricts traffic operations (i.e., low speed, constrained mobility with adjacent parallel parking movements). Considering the relatively low left turn volumes forecast for the proposed accesses, exclusive left turn lanes are not recommended in this area. 300033023.0000 033023_TIS.docx
Coletara Development 12 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 Additional gaps will also occur in the oncoming traffic along both Watson Parkway and Starwood Drive, due to the operations of the traffic signals in the study area, to facilitate left turns into the accesses. Ultimately, the introduction of a wider road width along either Watson Parkway or Starwood Drive, to accommodate turning movements, has the potential to increase travel speeds and negatively impact on pedestrian crossing opportunities. Considering that this area is designated as a mixed use node, with a low speed urban environment, it is concluded that no exclusive left turn lanes are required. Sufficient traffic mobility may be maintained along these corridors, without the introduction of exclusive left turn lanes, as reviewed further in a subsequent section to this report. 5.3 Right Turn Lane Requirements (Unsignalized Intersections) MTO guidelines (Geometric Design Standards For Ontario Highways) note that right turn lanes may be considered where right turn volumes exceed 60 vph or where right turning vehicles create a hazard or reduce capacity at the intersection. The right turn movements at the unsignalized intersection/accesses in the study area are forecast to have right turn volumes substantially below 60 vph through horizon year 2019 (Total Traffic conditions) and therefore right turn lanes/tapers are not required. 5.4 Intersection Operations 5.4.1 Operational Level of Services The intersections/accesses within the study area have been analyzed using Synchro Software, which uses methodologies based on the Highway Capacity Manual. The Levels of Service (LOS) and volume-to-capacity (v/c) ratios were determined for the signalized intersections, as well as for egress left turning movements at the unsignalized intersections/accesses (i.e., critical movement for unsignalized intersection). The LOS is a measure qualifying the amount of delay experienced by motorists. The delays associated with various LOS are summarized in the following tables for signalized and unsignalized intersections. Table 5.2 Level of Service Definitions For Intersections Level of Service Control Delay Per Vehicle Signalized Intersection (sec/veh) Control Delay Per Vehicle Unsignalized Intersection (sec/veh) A <= 10 <= 10 B > 10 and <= 20 > 10 and <= 15 C > 20 and <= 35 > 15 and <= 25 D > 35 and <= 55 > 25 and <= 35 300033023.0000 033023_TIS.docx

Coletara Development 15 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 The northwest bound through (NWB-T) movement at the intersection of Watson Parkway North/York Road is forecast to operate with long delays in the p.m. peak hour, under Total Traffic conditions and by horizon year 2019. However, the overall intersection is forecast to operate with acceptable delays and with sufficient reserve capacity. It is recommended that the signal timing be adjusted to mitigate the operational deficiency identified for the NWB-T movement. The southbound left/through/right movement at the intersection of Starwood Drive/ 11 Starwood Access/North (West) Access is forecast to operate with long delays (LOS F, 64.9 second delay) during the p.m. peak hour. However, significant reserve capacity remains for this movement (v/c=0.44), indicating that sufficient gaps are available. The forecast delays are not excess and therefore operations are considered to be acceptable, with no mitigation required. It is forecast that traffic operations at the remaining intersections and accesses in the study area will be acceptable through horizon year 2019. 5.4.2 Intersection Queuing Analysis The queuing storage requirements for the left turn lanes at the intersections in the study area and at the site accesses are summarized in the following tables, based on the queuing reports in Appendices E, F and G.

However, sufficient reserve capacity is forecast at this intersection (v/c = 0.71) to allow for an adjustment of the signal timing to mitigate this deficiency.

However, sufficient reserve 300033023.0000 033023_TIS.docx
Coletara Development 19 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 capacity is forecast at this intersection (v/c = 0.83) to allow for an adjustment of the signal timing to mitigate this deficiency. A small deficiency (7 metres) is forecast in the queuing storage for the westbound left turn lane at the Starwood Drive/Grange Road intersection, in the p.m. peak hour under Total Traffic conditions by 2019. However, sufficient reserve capacity is forecast at this intersection (v/c = 0.59) to allow for an adjustment of the signal timing to mitigate this deficiency. Average queuing at the site accesses is forecast to be minimal (ingress and egress), further reinforcing the previous conclusion that dedicated turning lanes are not required at these locations. No queuing conflicts are forecast for the intersections or accesses in the study area. 5.4.3 Traffic Signal Considerations at Starwood Drive/Watson Parkway North The existing intersection at Starwood Drive/Watson Parkway North is a tee configuration, operating under stop control on the Starwood approach. The previous construction of Watson Parkway North anticipates the future signalization of this intersection of two arterial roads. However, based on traffic counts taken in May 2012, the City confirmed that the traffic volumes at this intersection did not yet meet the warrants for the installation of traffic signals, at that time. It is anticipated that the City will install the traffic signals at the subject intersection once the eight hour warrant volumes have been met, based on ongoing traffic monitoring. This present study provides a further sensitivity analysis to assess the timing for these signals relative to the proposed site development. This analysis considers the forecast traffic volumes in horizon year 2014, including traffic generated from the development site and 2% growth in background traffic. It has been assumed that the off-peak traffic volumes will also increase, to maintain their same relative proportion to the peak period traffic. The resulting traffic volumes are shown on Figure A13 (Appendix A). The traffic warrant calculations are included in Appendix G and summarized in the following table: 300033023.0000 033023_TIS.docx

Based on the above analysis it is concluded that traffic signal warrants will not be met at this intersection, under ultimate completion of the proposed development in 2014. However, ongoing growth in background traffic, together with other significant development in the study area, will likely require the signalization of this intersection in the short term. As a further sensitivity analysis, the operations at this intersection have been reviewed under unsignalized conditions, using the same traffic volumes as used for the signal warrant analysis. The results of the Synchro analysis are included in Appendix G and summarized in the following table: Table 5.7 Sensitivity Analysis For Intersection of Starwood Drive/Watson Parkway North Unsignalized Conditions - 2014 Level of Service/delay* (volume/capacity) Intersection Traffic Condition Movement a.m. p.m. Saturday Peak Peak Peak Hour Hour Hour Starwood Drive/Watson Parkway North Background Plus Site Development * Delay only shown where LOS = F.

Coletara Development 21 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 developed in 2014. However, significant reserve capacity remains for this movement (v/c=0.67), indicating that sufficient gaps are available for this movement. The forecast delays are not excessive and therefore operations are considered to be acceptable under unsignalized conditions, with no mitigation required. However, as noted previously, it is expected that the City will continue to monitor the traffic at this intersection, as development continues in the overall area, with signals installed once volume warrants have been met. 300033023.0000 033023_TIS.docx
Coletara Development 22 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 6.0 Site Development Considerations 6.1 Access Considerations As noted previously the site is proposed to have two northern accesses, from Starwood Drive, and one eastern access, from Watson Parkway North. It is recommended that the following minimum sight distances be provided at the site accesses (based on Transportation Association of Canada criteria): Stopping sight distance for the posted speeds 65 metres for 50 km/h and 85 metres for 60 km/h; and Required left turn sight distances for left turn egress from the site (passenger cars) 100 metres for 50 km/h (2 travel lanes) and 130 metres for 60k/h (4 travel lanes). The available sight lines at the accesses are constrained by the horizontal curve in the roads, as follows: Starwood Drive (50 km/h) Northwest access 110 metres west, unrestricted to the east; Starwood Drive (50 km/h) Northeast access 160 metres west, unrestricted to the east; and Watson Parkway North (60 km/h) East access 180 metres south, 330 metres north. Therefore it is concluded that the proposed site access locations provide acceptable sight distances. It is noted that the City may include a parking lane on each side of Starwood Drive in the study area. It is recommended that this parking be sufficiently set back from the access locations, to ensure that the sight distances noted above are maintained. Considering the low speed urban environment, the proposed site driveways meet the typical corner clearance requirements for full move accesses. Similarly the proposed accesses onto Starwood Drive meet the desirable spacing between minor driveways. 6.2 Sight Triangle Considerations Departure sight triangles are not typically a requirement of private accesses, due to their low traffic volumes. However, the day lighting requirements at the intersection of 300033023.0000 033023_TIS.docx
Coletara Development 23 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 Starwood Drive/Watson Parkway North has been considered, since this may provide a constraint to the site development in that area. The existing intersection of Starwood Drive/Watson Parkway North is a tee configuration, under stop controls on the Starwood Drive approach. Assuming an ultimate right-of-way width of 30 metres on both Starwood Drive and on Watson Parkway North, with a design speed of 60 km/h on Watson Parkway North, the recommended dimensions of a visibility triangle in the southwest quadrant, if required, is calculated to be as follows: Starwood frontage - approximately 2.5 metres; and Watson Parkway frontage approximately 4.6 metres. These dimensions are based on the preliminary concept sketches that are presently available, and should be confirmed once more detailed survey information is produced as part of the detailed designs. As noted previously, it is assumed that the intersection of Starwood Drive/Watson Parkway North will be signalized in the near term and that this improvement will be in place shortly after occupancy of the proposed development. Since the intersecting traffic flows at a signalized intersection move at separate times, theoretically, sight triangles are not a requirement. However, due to the potential operating issues at signalized intersections, the City may request a visibility triangle that meets stop control criteria at this location, even after signalization. 6.3 Parking Considerations The parking considerations for the proposed development have been considered in a separate letter report. The primary conclusions and recommendations of that report are as follows: The average on-site parking demand for the proposed development, based on parking studies completed by the Institute of Transportation Engineers (ITE), is estimated to be 412 parking spaces. A parking lane is proposed along both sides of Starwood Drive, which will provide additional convenience parking for the proposed development. 300033023.0000 033023_TIS.docx
Coletara Development 24 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 6.4 Transit Considerations The subject site is well served by existing transit buses including the following: East Loop - Route 3A and 3B along Watson Parkway North; and Grange Route Route 14 along Watson Parkway North and Starwood Drive. Bus headways are 15 minutes in the a.m. peak period, 20 minutes in the p.m. peak period and 30 minutes in the off-peak period and on weekends. Bus stops are located on both sides of Watson Parkway North, immediately to the north of the Starwood Drive intersection. The presence of good accessible transit facilities is expected to reduce the trip generation from the rates assumed in this study. However to be conservative, no reduction has been made in auto trips, to reflect the potential shift in transportation mode in this area. 6.5 Pedestrian and Cyclist Considerations As shown on the conceptual cross sections (Figures A3 and A4, Appendix A), provided by the City, bike lanes are proposed on both Starwood Drive and on Watson Parkway North in the study area. On Starwood Drive the existing sidewalks presently terminate in the area of Frasson Drive, although a temporary asphalt walkway has been extended to the library on the north side of the road. It is expected that the sidewalks will be completed on both sides of this road, to Watson Parkway North, as adjacent development is completed. On Watson Parkway North the existing sidewalks presently terminate some distance to the north of Starwood Drive. It is expected that the sidewalks will be completed on both sides of this road, as adjacent development is completed in the study area. A secondary trail network is proposed a short distance to the east of the study area (i.e., along Watson Road). This trail will provide a potential connection to the primary trail network, along watercourse routes, as well as to parks and schools in the area. 300033023.0000 033023_TIS.docx
Coletara Development 25 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 7.0 Conclusions and Recommendations Based on the analysis completed, the main conclusions and recommendations of this study are as follows: The proposed development is forecast to generate total traffic (two-way) of 163 vph in the a.m. peak hour, 228 vph in the p.m. peak hour and 238 vph in the Saturday peak hour. A growth rate of 2.0% per annum (compounded) has been assumed for background traffic growth in the study area, exclusive of the traffic from the condominium development or from other external developments in the immediate study area. These external developments are forecast generate total traffic (net, two-way) of 778 vph in the a.m. peak hour, 1230 vph in the p.m. peak hour and 1357 vph in the Saturday peak hour. A time horizon of 2019 has been considered for future traffic impacts in this study. Forecast left turn volumes at the site accesses, in the p.m. peak hour and Saturday peak hour, are forecast to meet the Ministry of Transportation guidelines for the consideration of left turn lanes at these locations. However, the overall traffic volumes forecast on Watson Parkway, along with its four lane cross section, will provide sufficient operational flexibility to negate the need for an exclusive left turn lane at the site access. For the Starwood Drive accesses, the urban design concept for the corridor restricts traffic operations to a low speed urban condition. Therefore, given the low turning volumes at the site accesses, the corridor is expected to function adequately without the introduction of exclusive left turn lanes in this area. The Synchro analysis also shows that all accesses will operate acceptably, with minimal delays or queuing for the ingress movements. All intersections and accesses are forecast to operate acceptably through horizon year 2019 under Total Traffic conditions, with the exception of the following: Northwest bound through movement at the intersection of Watson Parkway North /York Road, that is forecast to have long delays. Adjustment of the signal timing is recommended to mitigate this deficiency. Southbound left/through/right movement at the intersection of Starwood Drive/11 Starwood Access/ North (West) Access, that is forecast to have long delays. However, sufficient gaps are available to accommodate this movement, with no improvements being required. Small deficiencies are forecast in the queuing storage at the Starwood Drive/ Watson Parkway North intersection (northbound left turn lane), at the Watson 300033023.0000 033023_TIS.docx
Coletara Development 26 Traffic Impact Study Proposed Residential Development (Watson Parkway North - Starwood Drive Node, City of Guelph) October 2013 Parkway North/York Road intersection (northeast bound left turn lane), and at the Starwood Drive/Grange Road intersection (westbound left turn lane). However, these deficiencies can be mitigated through an adjustment of the signal timing at these locations. The eastbound left turn movement at the intersection of Starwood Drive/Watson Parkway North is forecast to have long delays under Total Traffic Conditions in 2014, assuming stop controls on Starwood Drive (i.e., unsignalized). However, sufficient gaps are available to accommodate this movement in the short term. While it is forecast that the volume warrants for signalization at this intersection may not be met under this scenario, it is expected that these warrants will be met in the following five year horizon period. It is expected that the City will continue to monitor traffic at this location, with signals being implemented once the volume warrants have been met. Sufficient sight distances are available at the accesses to the proposed development. Sufficient spacing is provided between the proposed driveways and corner clearances meet typical requirements for full-move accesses. Under unsignalized conditions, a visibility triangle of approximately 2.5 metres (Starwood Drive frontage) by 4.6 metres (Watson Parkway North frontage) may be provided at the southwest quadrant of the intersection of Starwood Drive/Watson Parkway North. Assuming that signals will be installed at this intersection, there is no theoretical requirement for a visibility triangle at this location. However, if such a triangle is ultimately requested by the City, we would suggest that the upper limit of its dimensions be based on stop control criteria, as noted above. Parking considerations for the proposed development have been reviewed in a separate letter report. A maximum parking demand of 412 spaces on-site has been identified to accommodate this development. The proposed development is adequately serviced by existing transit facilities. 300033023.0000 033023_TIS.docx
