Executive Summary Hayden Homes is proposing to build a 253 -unit single-family addition to Woodland Ridge subdivision in southeast Springfield, Oregon. The site is a 72.36 acre parcel in south Springfield located between the Southern Pacific Railroad to the south and Phases I and 2 to the north and between 48w Street to the west and Phase 2 of the Pinehurst subdivision to the cast (see Figure 1). The site is planned to be built out in 6 phases annually from 2022 through 2027. The subdivision will have four connections to existing city streets: 5 F' Place to the north and Holly Street to the west will be connected in 2022 with Phase 3. Holly Street to the east will be open with Phase 7 in 2026 and Pinehurst Street will connect to the east near the southeast comer of the site with the final phase, Phase 8 in 2027. The five-year crash history found a total of 36 reported crashes at the study area intersections with 12 occurring at the Daisy at Bob Straub intersection. Along Daisy Street between 42"tl Street and Bob Straub Parkway 17 crashes were reported, with six crashes reported in 2019. Overall rear -end (4), angle (5), and sideswipe -overtaking (4) accounted for most of the 17 crashes. Intersection operations were analyzed for existing conditions in 2021, and buildout conditions in 2027 and five years after completion in 2032. The operational analysis was limited to six intersections; Daisy Street at Bob Straub Parkway, 51" Place, 48i6 Street, and 42ntl Street. Bob Straub Parkway at 57i° Street, and Main Street at 51" Place. Also included in the analysis is the investigation of a Stop sign warrant for the Forsythia Street approaches to 51" Place. For existing 202t conditions, all study area intersection movements operate at levclof-service (LOS) D or better except for the eastbound left -tum on Daisy Street at 42"a Street which operates at LOS = E. Previous studies have indicated that a traffic signal will meet warrants in the near future at Bob Straub Pkwy. at Daisy Street. 24-hour approach counts on all four legs of the intersection were taken on November 18, 2021. Reducing the data found the intersection to be just under the Manual on Uniform Traffic Control Devices (MUTCD) signal warrants 1, 2, and 3, but did just meet ODOT's 70% Preliminary Signal Warrant for interruption of continuous traffic. By buildout of Woodland Ridge in 2027, eastbound and westbound movements on Daisy at Bob Straub fell to F and E respectively. The intersection will now meet the MUTCD signal warrants and would operate at LOS = A. All other intersections remain at LOS D or better except the eastbound left -turns at 42nd and Daisy which is now at LOS =F. The intersection of Forsythia Street with 51" Place was investigated for a Stop sign for the minor movements on Forsythia Street. The 2016 MUTCD requires a combined vehicular, bicycle, and pedestrian volume entering the intersection from all approaches averages more than 2,000 units per day. A three day (Tuesday -Thursday) approach count on Forsythia found a maximum daily volume of It 5 eastbound and 84 westbound of Forsythia. For 51st Place, 45% of the site's buildout daily trips amounts to 1099 vehicles. The total of 115 +84 + 1099 equals 1298, well below the standard of 2000. By 2032, 5 years after completion, a signal at Bob Straub Parkway and Daisy Street will operate at LOS = A if signalized or LOS = F on both east- and westbound approaches on Daisy Street if not signalized. The eastbound left -tum on Daisy Street at 42v° Street will operate at LOS F and all other study area intersections operate at LOS = D or better. Based on the traffic impact analysis summarized above, we recommend approval of the development. Based on the trip distribution, the development would contribute 27 trips out of 1348 in 2027c from Woodland Ridge will impact the intersection of Bob Straub Parkway at Daisy Street. However, the estimated trips from the site at buildout, are a small percentage of the estimated total trips - 37 out of a total 1348 = 2.7% and this percentage will decrease over time.

Background 1, introduction, Location and Vicinity Map Hayden Homes is proposing to build a 253 unit single-family residential development addition to the Woodland Ridge Subdivision located in southeast Springfield. This addition is south of the two phases currently under construction. Figure 1 in Appendix A shows the location of the site in southeast Springfield. The purpose of this study is to document and analyze the potential traffic impacts of trips generated by the proposed development. 2. Description of Development Site The site is a 72.36 acre parcel in southeast Springfield located between the Southern Pacific Railroad to the south and Phases 1 and 2 to the north, and between 48" Street to the west and Phase 2 of the Pinehurst subdivision to the east. The site is planned to be built out in 6 phases annually from 2022 through 2027. 1 h site plan (see Figure 2 in Appendix A) shows the layout of the 253 single-family units. Access is provided by 51" Place to the north and Holly Street to the west in 2022: Holly Street will be extended cast to a developed subdivision with phase 7 in 2026; and Pinehurst Street will be extended east with phase 8 in 2027. The intersections of Daisv Street at Bob Straub Pkwy., 5l" Placc, 48'h Street, and 42nd Street, along with Bob Straub Pkwy, at 57"` Street, and Main Street a151" Place have been identified for analysis. 3.

There were two crashes reported at the Daisy @ 47"' Street intersection and one crash each reported at the intersections of 43'" Street, 51"Place, and Ridge Drive with Daisy Street. There were a total of six collisions with midbtock parked vehicles on Daisy Street In addition there were three sideswipe collisions on Daisy, two eastbound and one westbound. One collision involved a vehicle backing up. That vehicle backed out of a driveway midway between 49'" Place and 51" Street and struck a westbound vehicle resulting in minor injuries. The other occurred when a vehicle on 44`" Street backed into the Daisy Street intersection resulting in a minor injury. 5, Transit Lane Transit District provides transit service in the Fugene-Springfield Metro area. Route 11 - Thurston Runs between downtown and the Thurston area. Near the Woodland Ridge subdivision, the closest bus stops in both directions are on Main Street. 6. Pedestrian and Bicycle Facilities Daisy Street has sidewalks on both sides between Bob Staub Pkwy and 42" Street except for the north side of Daisy from 51" Pl. to 52°" Street. That block of Daisy is only 24 feet in width. 51"Pl. has no sidewalks between Daisy and Main Streets. Sidewalks exist on both sides of Holly Street and 48'" Street to the west and 51"Pl. from Woodland Ridge northwest to Daisy Street. Main Sheet can be reached by sidewalk on 49" Place/Aster Stteet148"' Street; of on 52"" Street or 52" Place. All streets in the Woodland Ridge subdivision will have sidewalks on both sides of the streets. The Springfield Transportation System Plan, adopted in 2014, has several pedestrian and bicycle projects in the Woodland Ridge study area. The following projects are listed on the Capital Improvement Plan. R-44: At the Bob Straub Parkway at Daisy Street intersection, a pedestrian/bicycle signal and crossing or under crossing are proposed at Daisy Street. R-39: Construct collector extension of 48a Sheet from Daisy Street north to Aster Street south of Main. R-42: Extend Holly Street from S 48'^ Street to S. 57's Street. - Woodland Ridge will build the section on site, connecting from S 48th to the Holly Street stub at the east site boundary. R-41: Construct new collector IS 50 St.) from Main Street to Daisy Street (More than 20 years out.) PB -36: Daisy/Virginia Bike Boulevard IS. 32"" to Bob Straub Pkwy.) Phase I completed between 42" Street and 51" Street. Roundabouts are proposed for Daisy at 42" and 51"PL The Virginia -Daisy Bikeway Project, PB -36, will provide an east -west bike network option that will serve as an alternative to Main Street and will include design development that considers, but is not limited to, treatments such as striping of bicycle lanes, sharrows, traffic calming infrastructure, intersection treatments, automobile traffic diversion, limited lighting additions, ramp improvements, speed and designation signs, and a crossing improvement at 42nd St. Additionally, the project strives to enhance the overall appeal of the corridor for all users and residents, improve pedestrian safety and usage, and provide traffic calming to emphasize safety and active transportation along the street. The proposed roundabouts at 486 Street and 51" Place will be included as potential improvements to those study area intersections in the traffic analysis section.

Trip Distribution During the PM peak hour trips are predominantly work or shopping to/from home. These trips are made to and from the industrial and commercial areas in the Eugene - Springfield area but predominantly to and from Fast Springfield. In discussions with the City, the following distribution plan was adopted based on LCOG model runs: • 40% will use the Highway 126 freeway to the North and West; 25% from the Bob Straub Parkway north of Daisy Street and 15% from Main Street east of 51" Place. • 25% will use Bob Straub Pkwy north from. Daisy Street in Highway 126 freeway at Main Street. 15% will use Main Street east to Highway 126 freeway at Bob Straub Pkwy.. • 5% will use 4P Street north from Main Street and west from 51" Place. • 25% will use Daisy Street cast of 51"Place to Bob Straub Parkway with 5% continuing east and 20% turning north onto Bob Straub Pkwy. • 45% will use 51" Place north of the subdivision to Daisy Street • 100/9 will use Holly Street east to 55i6 Street... - then 5% north to Ivy Street to 551h Place to Glacier Driver to Bob Straub Pkwy and north. - and 5% south to Mt. Vernon Rd., then east to Bob Straub Pkwy and south. • 40% will use Holly Street and 4V Street to Daisy Street and continue east on Daisy to 42" Street and disperse north, east. and south. The City of Springfield's Scope of Work has selected the following intersections for analysis: Bob Straub Parkway at Daisy Street and 57r6 Street; 51 at Place at Daisy Street and Main Street; and Daisy Street at 45" Street and 42" Street. The City has also requested a Stop Sign Warrant Analysis for the 51" Place and Forsythia Street intersection built in Phase 1 of the development. And the City is requesting a Signal Warrant analysis for Bob Straub Parkway at Daisy Street/57th Place. Access Engineering LLC December Woodland Ridge Subdivision Traffic Impact Analysis Page 6 3. Existing Traffic Conditions Manual traffic classification counts were taken at the following study area intersections: Daisy Street at Bob Straub Parkway, 51" Place, 48'^ Street, and 42'" Street: Main Street at 51" Place; and Bob Straub Parkway at 57'" Street Counts were taken from 4 to 6 PM on Thursday November 0, 2021 by Quality Counts LLC. The peak hour varied from intersection to intersection so the individual peak hour volumes were used due to the overall length of the study area. Quality Counts also performed 24-hour counts on each leg of the Bob Straub Parkway at Daisy Street intersection on November 18" for a traffic signal investigation. The traffic counts can be found in Appendix B. 4. Seasonal Factor The intersection counts were taken on November 9's, 2021. In order to assess the worst case traffic impacts these counts should be translated to the highest traffic month of the year. ODOT provides guidelines for determining design hour volumes (DITV). Design hour volumes are the 30th highest hour volume for a given year. ODOT's Analysis Procedures Manual (APM) provides three methods for evaluating the seasonal factor. The first method is to consult an existing Automatic Traffic Recorders (ATR) in the nearby area. There are no ATR's nearby. The second method is to use the ATR Characteristic Table to find a similar highway. A check of highways in the Table found no good matches. The third method is the Seasonal Trend Table. The cormnuter seasonal trend is estimated using ODOT's 2020 Seasonal Trend Table. The resulting seasonal factor of 1.08 and is applied to all existing movements in the study area during the peak hour. The calculations are shown in Appendix B and the DH V's in the study area are shown on Figure 3 in Appendix A. 5. Intersection Operations Analysis - General Procedures The City of Springfield and Lane County use different mobility standards. For City streets, Springfield uses Levcl-of-Service (LOS) which is based on average delay per vehicle. LOS measures the quality of traffic flow at an intersection by estimating the average delay encountered. It is described by a letter scale from "A" to "F (see below). Level of Service Traffic Signal Stop sign A o10 sec s>10 sec 10-20 see 10-15 sec 20-35 sec 15-25 sec Level of Service Traffic Signal Stop sign D 35-55 sec 25-35 sec E 55-80 sec 35-50 sec F >80 sec >50 sec Springfield requires TIA's to identify all intersections with a LOS of E or worse. Lane County has the following requirements: (a) Signalized, All -way Stop, or Roundabout Controlled Intersections: The intersection as a whole must operate with a Level of Service (LOS) "E" or better and a volume to capacity (v/c) ratio not higher than 0.85 if inside an Urban Growth Boundary. For Bob Straub Parkway, an urban minor arterial, inside a UGB in the Eugene -Springfield Metro Area, the maximum allowed volume to capacity ratio is 0.85. (b) Two-way Stop and Yield Controlled Intersections: All public street intersection approaches serving more than 20 vehicles during the highest one hour period on an average weekday (typically, but not always the evening peak period between 4 p.m. and 6 p.m. during the spring or fall) must operate with a LOS "E" or better and a v/c ratio not higher than 0.95 if inside and UGB. Access F;ngineering LL(- Dcecmber 15, Woodland Ridge Subdivision Traffic Impact Analysis Page 7 6. 2021 Existing Intersection Operational Analysis The Synchm program is used to evaluate the operation of all intersections in the study area. The heavy vehicle percentages, and bike and pedestrian numbers from the traffic counts were used. SimTmffic was used to evaluate the queue lengths at the study area intersections following the guidelines in Chapter 8 of ODOT's APM. Five runs with a random seed were averaged. The 95" percentile queues are reported and are rounded to the next nearest 25 -foot increment. Figure 3 in Appendix A shows the existing layout of each study intersection and the design hour volumes (DHV's) for the PM peak hour. The Synchro reports are in Appendix C.

Access Engineering LLC December 15, 2021 Woodland Ridge Subdivision Traffic Impact Analysis Pane 8 Previous studies in the area have indicated that the intersection of Bob Straub Parkway at Daisy Street may meet the minimum requirements for a traffic signal in the near future. As a result, hose counts were taken by Quality Counts on all approaches to the Bob Straub Parkway at Daisy Street intersection on November 18, 2021. The data is found in Appendix B. The ODOT Preliminary Signal Warrant Analysis was run for the intersection using 70% of the standard warrant due to the 45 MPH speed limit on Bob Straub Parkway. The results indicate that the intersection does meet the minimum interruption of continuous traffic, Case B, needed to warrant a signal installation. The 24-hour tmfiic count data from November 18th showed that the intersection falls just short of the Manual on Uniform Traffic Control Devices (MUTCD) Warrant 3, Peak Hour. One minor approach must have 100 vehicles per hour (veli) to meet the 70% of Warrant but eastbound Daisy was the highest approach at only 97 vph westbound during the AM peak hour and 92 vph in the PM peak hour. The intersection also falls just short of the requirements for MUTCD Warrants I & 2, the Eight -Hour and the Four -Hour Warrant Volume warrants. As a result, for future years' analyses, both a 2 -way Stop and a traffic signal will be analyzed for that intersection. 7. 2027 Intersection Operational Analysis The Woodland Ridge phases 3 through 8 is planned to be completed in 2027. Figure 4 shows the full buildout trips assigned to the study area. Lane Council of Governments has provided traffic model data a growthrate for traffic in southeast Springfield to use to estimate traffic background traffic in 2027. The growth rate varied by intersection from: 3.95%/yr all approaches at Bob Straub @ Daisy and 57th •Daisy @ 42nd - 1.275% all approaches •Main @ 51st PI - 2.0% Main approaches only •Daisy @ 51st P1 & 48th: 1.0 % all approaches unless 48th is extended. Figure 5 in Appendix A shows the DHV's in 2027 for the no -build conditions compared to the buildout of Woodland Ridge. The Synchro reports are in Appendix C. With a growth rate of 3.95%/year, MUTCD Warrant #3 will now be met with or without the development at the Bob Straub Parkway at Daisy Street intersection. Table 6 on the following page shows the results of the operational analysis for 2027 traffic levels for the full buildout with and without a traffic signal at Bob Straub Parkway and Daisy Street. By full buildout of Woodland Ridge in 2027, the eastbound Daisy Street approach to Bob Straub Parkway is now at LOS = F with queues exceeding the available storage without a traffic signal. 8. 2032 Intersection Operational Analysis Five years after buildout of Woodland Ridge, background traffic is assumed to continue to grew at the same rate.

The only significant impact is at the Bob Straub Parkway intersection with Daisy Street where the existing Stop sign control results in the current LOS = D. By buildout of Woodland Ridge, it is assumed that 25% of Woodland Ridge trips would use the Bob Straub Parkway via Daisy Street and 51" Place and the LOS at buildout in 2027 falls to F at DaisyiBob Straub Pkwy. The ODOT Preliminary Signal Warrant Analysis found that the intersection currently (2021 traffic) meets the 70% Warrant - (Case B) - minimum interruption of continuous traffic. The intersection was also very close to meeting the MUTCD signal warrants (Warrants 1, 2, & 3). By buildout of Woodland Ridge, the Bob Straub Parkway at Daisy Street exceeds the signal warrants due to an expected growth rate of almost 4% per year due continued developments to the south on Bob Straub Parkway as well as the Woodland Ridge development. At the intersection of Daisy Street at 42nd Street, the eastbound left -tum movements currently experience LOS = E. By 2027, that movement falls to LOS = F with or without Woodland Ridge, The City of Springfield plans to convert the intersection into a roundabout at some point in the future. All other movements at the study area intersections operate at LOS D or better through 2032. 9. Stop Sign Request at Forsythia and 51r Place The City of Springfield has received a request to install a Stop sign for east and west traffic on Forsythia Street at 51"Place which was constructed during phase 1 of this development. The 2016 edition of the MUTCD (Manual on Uniform Traffic Control Devices) has the following guidance: 03 YIELD or STOP signs should be used at an intersection if ane or more of Ute following conditions exist An intersection of a less important road with a roar road where application of the normal right -o f-wav rule would not be expected to provide reasonable compliance with the Imv; A street entering a designated through highway or street; and/or An unsignalized intersection in a signalized area. None of these conditions currently apply since 51"Place does not currently extend south of Forsythia. With development of phases 3 through 8, however, 51"Place, though categorized as a local street, will become one of the major access routes for phases 3 through 8 carrying an estimated 45% of the site traffic. 04 In addition, the use of YIELD or STOP signs should be considered at the intersection of iwo minor streets or local roads where the intersection has more than three approaches and where one or more of the following condition., exist: The combined vehicular, bicycle, and pedestrian volume entering the intersection front all approaches averages more than 2,000 emits per day; At full buildout, 51" Place is projected to receive 45% of the traffic from phases 3 through 8. Those phases are expected to generate a total of 2442 daily trips. For 51" Place at Forsythia.. 45% of those trips equals only 1099 daily trips. Road tube traffic counters were set out on the Forsythia Street approaches to 51st Place from Tuesday December 71h to Friday December IOth. On the average day there were 115 vehicles eastbound approaching 51 st Place and 84 westbound The highest hourly volumes were: 18 eastbound and 14 westbound. The total daily trips = 1099+115+84 =1298 vehicles per day, is well below the threshold for a control sign. Access Engineering LLC December 15, 2021 Woodland Ridge Subdivision Traffic Impact Analysis Paee 12 The ability to see conflicting traffic on an approach is not sufficient to allow a road user to stop or yield in compliance with the normal nghbof--way rude if such stopping or yielding is necessary, There are no impediments to sigbt distance on either Forsythia approach except for occasional parked can. ODOT provides safe stopping distances (SSD) for various speeds. For 25 MPH the SSD is 155 feet. Them are no impediments to vision from either Stopped position. See photos in Appendix C. Crash records indicate thatfire or more crashes that involve the failure to yield the right-of-way at the intersection ander the normal right-of-way rule hate been reported within a 3year period or that three or more such crashes have been reported within a 2 -pear period. No crashes have been reported at the intersection. 05 YIELD or STOP signs should not be used for speed control. Section 211.06 STOP Sign Applications Guidance: 01 At intersections where a fidt.stop is rax necessan• at all times, consideration .should first he given to using less restrictive measures such as YIELD signs (see Sections 2B. 08 and 2B.09). 02 The use afS7'0P signs an the minor -street approaches should be considered if engineering judgmem indicates that a stop is always required because of ane or more of the following conditions: The vehicular traffic volumes on the through street or highway exceed 6,000 vehicles per day,' A restricted view exists that requires road users to stop in order to adequately obsen•e confiteting tragic on the through street or highway; and/or Crash records indicate that three or more crashes that are susceptible to correction by the installation. afa STOP sign hme been reported within a 12 -month period, or that five or more such crashes have been reported within a 2 -year period. Such crashes include right-angle collisions im'olving road users on the minor -street approach failing to yield the right -of -wap to traffic on the through street or highway. The intersection does not now, or wilt have after Woodland Ridge is complete, the required minimum traffic, does not have a restricted view, or have a crash history. Based on this data a Stop sigh on Forsythia at 51st Place does not meet warrants. Access Engineering LLC December 15, 2021 Woodland Ridge Subdivision Traffic Impact Analysis Page 13 III. Conclusions and Recommendations • Phases 3 through 8 of Woodland Ridge, a single-family residential subdivision in southeast Springfield, will generate 2442 daily trips at buildout of the site scheduled for 2027. • There were a total of 36 crashes at the study intersections, 12 occurring at the Bob Straub Pkwy. at Daisy Street intersection; nine were angle crashes involving eastbound/southbound vehicles. On Daisy Street between Bob Straub and 42n° them were 17 crashes during the five year study, six occurring in 2019. • The distribution of new trips will be scattered over the Eugene -Springfield Metro Area. The city has specified the analysis to be confined to Daisy Street from 42nd Street to Bob Straub Parkway including the intersection with 51" place: Bob Straub Parkway at Daisy and 57" Streets, and 51" Place at Main Street during the PM peak hour only for the buildout of development. In addition, the City of Springfield has received a request for Stop sign(s) on Forsythia Street at 5 1" Place. • The operational analyses of the study area intersections for existing, 2021 conditions, finds that the Bob Straub at Daisy Street intersection provides a LOS = D for eastbound movements. However, the intersection does meet ODOT's 70% Preliminary Signal Warrant, but does not meet MItTCD warrants at this time. All other intersections studied operated at LOS D or better except for eastbound left -turns on Daisy at 42"d Street (LOS=E). • By buildout of Woodland Ridge in 2027, eastbound Stop movements on Daisy at Bob Straub will fall to LOS —F and westbound movements are LOS=E. At this time the intersection will exceed the MUTCD warrants 1 through 3 for provision of a traffic signal. If signalized, the intersection will operate at LOS = A but eastbound and westbound queues remain. The eastbound left -tum on Daisy Street at 42"d Street will fall to LOS —F. All other movements there and at the remaining study area intersections operate at LOS = D or better. • By 2032, a signal at Bob Straub Parkway and Daisy Street will remain at LOS =A. The eastbound left -tum on Daisy Street at 42"d Street will operate at LOS F and all other study area intersections operate at LOS =D or better. • Stop sign warrants for Forsythia Street at 5 P' Place are not met and will not be met at full buildout of Woodland Ridge. Based on the above findings, we recommend approval of the proposed Woodland Ridge development expansion. Traffic from Woodland Ridge will impact the intersection of Bob Straub Parkway at Daisy Street. However, the estimated nips from the site (14 eastbound left-mms and 23 southbound right -turns) at buildout, 2027, is a small percentage of the estimated total trips - 37 out of a total 1348 = 2.7% and this percentage will continue to decrease over time.
