81 TRAFFIC IMPACT STUDY for Leen Subdivision February 2, 218 PREPARED FOR: Nels Leen & Associates PREPARED BY: DRAFT TRAFFIC WORKS, LLC 224 St. George Ln, Suite 1, Chico, CA

82 Traffic Impact Study Leen Subdivision February 2, 218 Why did you perform this study? YOUR QUESTIONS ANSWERED QUICKLY This Traffic Impact Study evaluates the potential traffic impacts associated with the proposed Leen Subdivision project. This study of potential transportation impacts was undertaken for community planning and CEQA review purposes and to determine what traffic controls or other mitigations may be needed to reduce potential impacts, if any are identified. What does the project consist of? The proposed project is a 21 unit single family detached housing subdivision. The site is located on the south side of Stanley Avenue east of the Dayton Road / Stanley Avenue intersection in Butte County, CA. How much traffic will the project generate? The Leen Subdivision project is anticipated to generate 198 Daily trips, 16 AM peak hour trips, and 21 PM peak hour trips. Are there any traffic impacts? With the addition of project traffic, the Dayton Road/Stanley Avenue intersection is projected to operate at acceptable level of service conditions (LOS B or better) under Existing Plus Project conditions during both the AM and PM peak hours. Additionally, Stanley Lane and the Stanley Lane/Street A project intersection will operate at acceptable level of service conditions (LOS A ) under Existing Plus Project conditions. No notable traffic operation impacts are anticipated with the project. Are any improvements recommended? Stanley Avenue has a relatively narrow paved width (16 feet at the narrowest but typically 17 to 18 feet) which is less than the 2 foot minimum roadway width recommended in A Policy on Geometric Design of Highways and Streets (24) published by the American Association of State Highway and Transportation Officials (AASHTO) and narrower than Butte County standards for new County roadways. To provide a safe and efficient roadway with increased traffic, the applicant will provide a proportionate cost sharing contribution for widening of the pavement section on Stanley Avenue to a 2 foot width from Dayton Road to the project entry point. If the County requests the applicant to physically construct widening improvements in an dollar amount equal to the proportionate share, in lieu of paying the fee, it is our recommendation that the widen begin at Dayton Road and move east to the extent possible with the fee amount. The greatest widening benefit will be realized where traffic volumes are the highest, which is closest to Dayton Road. Page 1 of 13

84 Traffic Impact Study Leen Subdivision February 2, 218 INTRODUCTION This report presents the findings of a Traffic Impact Study completed to assess the potential impacts on local roadways and intersections associated with development of the Leen Subdivision project. This Traffic Impact Study has been prepared to describe existing traffic conditions, quantify traffic volumes generated by the proposed project, identify potential impacts on all modes of travel, document findings, and make recommendations to mitigate impacts, if any are found. Study Area and Evaluated Scenarios The project is generally located on Stanley Avenue east of the Dayton Road / Stanley Avenue intersection in Butte County, CA. The following intersections and roadway segment were analyzed based on scoping discussions and correspondence with Butte County staff: Dayton Road / Stanley Avenue Stanley Avenue / Street A (project access) Stanley Avenue roadway segment Dayton Road to the project site The locations of these intersections and the study roadway segment are shown on Figure 1 and the project site plan is provided in Figure 2. This study includes analysis of both the weekday AM and PM peak hours as these are the periods of time in which peak traffic conditions are anticipated to occur. The evaluated development scenarios are: Existing Conditions (no project) Existing Plus Project Conditions Analysis Methodology Level of service (LOS) is a term commonly used by transportation practitioners to measure and describe the operational characteristics of intersections, roadway segments, and other facilities. This term equates seconds of delay per vehicle at intersections to letter grades A through F with A representing optimum conditions and F representing breakdown or over capacity flows. The LOS for a Two Way STOP Control (TWSC) intersection is defined by the worst movement delay. Signal and All Way STOP Control (AWSC) LOS is reported for the overall intersection. The complete methodology is established in the Highway Capacity Manual (HCM), 21, published by the Transportation Research Board. Table 1 presents the delay thresholds for each level of service grade at un signalized and signalized intersections. Level of service calculations were performed for the study intersections using the Vistro 5. software package with analysis and results reported in accordance with the 21 HCM methodology.

C Stable conditions with 15 to 25 2 to 35 significant affect from other vehicles. D High density traffic conditions 25 to to 55 still with stable flow. E At or near capacity flows. 35 to 5 55 to 8 F Over capacity conditions. > 5 > 8 Source: Highway Capacity Manual (21), Chapters 16 and 17 The criteria for evaluating roadway LOS is outlined in the Butte County General Plan 23. For the roadway segment LOS calculations, roadway capacity is determined by facility type, as shown in Table 2, and roadway volume based on peak hour segment volume. Roadway LOS was determined by comparing the observed and projected peak hour bi directional roadway volumes to the volumes shown in Table 2.

Traffic Impact Study Leen Subdivision February 2, 218 Level of Service Policy Butte County established county wide level of service criteria standards and thresholds in the Butte County General Plan

86 Traffic Impact Study Leen Subdivision February 2, 218 Level of Service Policy Butte County established county wide level of service criteria standards and thresholds in the Butte County General Plan 23. Circulation Policy CIR P6.1 is most applicable to this project location. Therefore, the trigger requiring traffic mitigation is crossing the threshold between LOS C and LOS D. EXISTING TRANSPORTATION FACILITIES Roadway Facilities A brief description of the key roadways in the study area is provided below. Dayton Road within the project area is a two lane roadway running generally north south with one lane in each direction. It is classified as a Major Roadway according to the Butte County General Plan 23 (Figure CIR 1). The City of Chico General Plan classifies Dayton Road as a Major Arterial. The posted speed limit is 45 miles per hour (mph) within the study area. Stanley Avenue is an east west local roadway. The typical roadway width is 17.5 feet between Dayton Road and the project site with the narrowest measured width at 16 feet. It is classified as a Local Road in the Butte County General Plan 23. The posted speed limit is 25 mph. Alternative Travel Mode Facilities No sidewalks or bicycle lanes are present on any of the roadways in the study area. There are approximately three to five foot wide paved shoulders on both sides of Dayton Road in the study area. Currently there are no fixed route public transit services (B Line) available within the project area. The project location is semi rural and therefore very few walking or biking trips are currently made from the existing neighborhood to the City of Chico urbanized area primarily due to the travel distance and secondarily because the connecting facilities have limited pedestrian or bicycle facilities.

87 Traffic Impact Study Leen Subdivision February 2, 218 EXISTING CONDITIONS Existing Traffic Volumes Existing traffic volumes were determined by collecting new turning movement counts during the AM and PM peak periods at the Dayton Road / Stanley Avenue intersection and 24 hour roadway traffic volumes on Stanley Avenue on an average mid week day in January 218 with local schools and Chico State University in regular session. Existing intersection lane configurations, controls, and peak hour traffic volumes are shown in Figure 3, attached, and 24 hour roadway segment volumes are shown graphically in Exhibit 1. Exhibit 1. Hourly Roadway Volumes on Stanley Avenue # of Vehicles AM Peak Hour, 36 PM Peak Hour, 46 Time Westbound Volume Eastbound Volume Total Volume As shown in Exhibit 1, the AM and PM peak hour traffic volumes on Stanley Avenue are 36 and 46 vehicles, respectively. In total, there were 424 vehicles counted on Stanley Avenue during the mid week 24 hour period. Complete 24 hour roadway count data with volume, classification, and speed information is provided in Appendix A. Page 6 of 13

88 Traffic Impact Study Leen Subdivision February 2, 218 Existing Roadway Level of Service Roadway Level of Service was determined by comparing existing peak hour bi directional roadway segment volumes to the thresholds shown in Table 2. The Stanley Avenue roadway segment Level of Service is shown in Table 3. Table 3: Existing Conditions Roadway Level of Service Summary Segment Classification Scenario Peak Hour Volume # of Lanes LOS Stanley Ave 2 Lane Local Road Existing 46 2 A As shown in Table 4, the Stanley Avenue roadway segment is operating at acceptable LOS A conditions during the peak hour. The peak hour volume on Stanley Avenue is extremely low and is approximately 1/1 th of the volume needed to reach the LOS C threshold in Table 2. The roadway has significant surplus capacity. Existing Intersection Level of Service Analysis Intersection Level of service calculations were performed using the existing traffic volumes, lane configurations, and traffic controls. The results are presented in Table 4 and the calculation sheets are provided in Appendix B, attached. Table 4: Existing Conditions Intersection Level of Service Summary Existing AM Existing PM Intersection Control Delay 1 LOS Delay 1 LOS Dayton Road / Stanley Ave Side Street Westbound Approach A 9.9 B STOP Southbound Left A 7.62 A 8.25 Notes: 1. Delay is reported in seconds per vehicle for the overall intersection for signalized intersections, and for the worst approaches/movements for side street stop controlled intersections. As shown in Table 4, the existing study intersection currently operates at acceptable levels of service (LOS B or better). Intersection Sight Distance An intersection sight distance evaluation was performed for the side street (westbound) approach of the Dayton Road / Stanley Avenue intersection. No significant issues were identified as the sight distances were deemed to be essentially unlimited from the appropriate location 14 feet back from the edge of travel way in accordance with nationally accepted sight distance measurement criteria (A Policy on Geometric Design of Highways and Streets (24) published by the American Association of State Highway and Transportation Officials (AASHTO)). Page 7 of 13

89 Traffic Impact Study Leen Subdivision February 2, 218 It is important to note that further vegetation growth adjacent to the sight lines looking in both directions (north and south) could impact the current available sight distance in the future. Butte County and adjacent property owners, as appropriate, should remove the vegetation potentially affecting sight lines on a regular basis to insure adequate intersection sight distance is maintained. No design feature or geometric changes are needed at the Dayton Road/Stanley Avenue intersection. PROPOSED PROJECT Project Description The project site is located on two existing contiguous parcels with direct access to the south side of Stanley Avenue approximately 1,5 feet east of Dayton Road. The proposed project consists of 21 residential lots and Lot A which is to be preserved as Open Space pursuant to the Clustered Development Ordinance. Parking The project will provide on site parking in accordance with Butte County development standards. Trip Generation Trip generation rates for the proposed project were obtained from the Trip Generation Manual, 1th Edition, published by the Institute of Transportation Engineers (ITE). Table 5 provides the Daily, AM Peak Hour, and PM Peak Hour trip generation calculations for the proposed project. Table 5: Trip Generation Estimates Land Use (#) Size Daily Single Family Detached Housing (21) 21 Dwelling Units A.M. Peak P.M. Peak Total Entry Exit Total Entry Exit Notes: ITE 1th Ed. Trip Generation Rates For Single Family Detached Housing (Per Dwelling) Daily: 9.44, AM:.74, PM:.99 As shown in Table 5, applying the ITE Trip Generation Manual trip rates, the proposed project is anticipated to generate 198 total daily trips, 16 total AM peak hour trips, and 21 total PM peak hour trips. Vehicle Miles Travelled (VMT) Estimation With adoption of and implementation of California Senate Bill 743, Vehicle Miles Travelled (VMT) is an important consideration and a key metric of vehicular travel contributions to Green House Gas (GHG) emissions and energy consumption. VMT is typically expressed in miles per day and can simplistically be calculated by multiplying the number of daily project generated trips by the anticipated trip length. The average trip length and percentage of each type of home based trip in Butte County was obtained from the California Emissions Estimator Model (CalEEMod). Table 6 shows each home based trip type and the associated average trip length in Butte County. Page 8 of 13

Project Vehicle Miles Travelled Res H O Trip Length (miles) Res H W Trip % Res H S Trip % Res H O Trip % Average Trip Length (miles) Total VMT per day (198 Trips) ,798 As shown in Table 6, the project is estimated to cause an increase in VMT of 1,798 miles per day. This is likely a very conservative estimate since the project is located closer to the core urban area than the Butte County average travel distances. Butte County currently does not have any specific thresholds or significance criteria related to VMT, but does have general goals of reducing VMT and GHG emissions. Project Access One access point is proposed for the project, located on Stanley Avenue, as shown on Figure 2. The access point is proposed as a full access intersection allowing for all possible movements with side street stop control (STOP sign on Street A). We understand secondary access is not required per Butte County standards based on the relatively small number of proposed homes and the proposed street design. Field review of the access location indicated no notable issues for intersection sight distance. Adjacent parcels have large trees and other shrubs along Stanley Avenue but they are not anticipated to impact intersection sight distance at this time. As is common in most locations, vegetation along Stanley Avenue may have to be trimmed and properly maintained over time to maintain appropriate sight lines. Trip Distribution and Assignment Traffic generated by the project was distributed to the road network based on the location of the project and for consistency with existing local traffic patterns. The following trip distribution percentages were used for distributing the project traffic: 75% travelling to/from the north via Dayton Road 25% travelling to/from the south via Dayton Road 1% of the project generated trips were assigned to/from the west on Stanley Avenue from the project site. A time travel comparison was conducted to compare the difference in travel time drivers would experience if they travelled either east or west from the site ultimately to Dayton Road. The travel time east through the neighborhood, using Diamond Avenue and McIntosh Avenue, was found to be twice that of simply using Stanley Avenue to Dayton Road. No notable number of drivers would choose a route that is twice as time consuming to reach the same destination. Review of the roadway network indicates that project traffic would not use Marian Avenue as there would be no benefit in doing so. It is clear that all project traffic should be assumed to choose the most direct route of Stanley Avenue to/from the west to Dayton Road. Page 9 of 13

91 Traffic Impact Study Leen Subdivision February 2, 218 The Existing Plus Project intersection lane configurations and the project trip assignment are shown on Figure 4, attached. EXISTING PLUS PROJECT CONDITIONS Existing Plus Project Roadway Level of Service Roadway Level of Service was calculated by comparing existing plus project peak hour bi directional roadway segment volumes to the thresholds shown in Table 2. The Stanley Avenue roadway segment Level of Service is shown in Table 7. Table 7: Existing Plus Project Conditions Roadway Level of Service Summary Segment Classification Scenario Peak Hour Volume # of Lanes LOS Stanley Ave 2 Lane Local Road Existing Plus Project 67 2 A As shown in Table 7, the Stanley Avenue roadway segment is anticipated to operate at acceptable level of service (LOS A ) conditions during the peak hour. The proposed project only adds 21 peak hour trips on Stanley Avenue and the roadway peak hour volume is still extremely low. The anticipated average daily traffic volume (ADT) under Existing Plus Project conditions is 622 vehicles per day. Existing Plus Project Intersection Level of Service Analysis Existing Plus Project traffic volumes were developed by adding the project generated trips (Figure 4) to the existing traffic volumes (Figure 3) and are shown on Figure 5, attached. Existing Plus Project condition Peak Hour Factors (PHF) and lane configurations were assumed to remain the same as existing conditions. Table 8 presents the level of service analysis summary for the Existing Plus Project scenario. Detailed calculation sheets are provided in Appendix C, attached. Table 8: Existing Plus Project Conditions Intersection Level of Service Summary Existing + Project AM Existing + Project PM Intersection Control Delay 1 LOS Delay 1 LOS Dayton Road / Stanley Ave Side Street Westbound Approach B 1.

Delay is reported in seconds per vehicle for the overall intersection for signalized intersections, and for the worst approaches/movements for side street stop controlled intersections. With the addition of project traffic, both study intersections are projected to operate at acceptable level of service (LOS B or better) conditions during both the AM and PM peak hours. The proposed project would, on average, increase delay by less than one second per vehicle during the peak hours. Page 1 of 13

92 Traffic Impact Study Leen Subdivision February 2, 218 ROADWAY WIDTH Stanley Avenue has a relatively narrow paved width (16 feet at the narrowest but typically 17 to 18 feet) which is less than the 2 foot roadway width recommended in A Policy on Geometric Design of Highways and Streets (24) published by the American Association of State Highway and Transportation Officials (AASHTO). The existing roadway is also narrower than Butte County standards for new construction within the County. Table 9 shows the recommended minimum width of traveled way, by roadway volume, for rural crosssections as set forth by AASHTO. Table 8. Minimum Width of Traveled Way (AASHTO Exhibit 5 5) Design Speed (mph) Minimum width of traveled way (ft) for specified design volume (veh/day) under 4 4 to to 2 over Width of graded shoulder on each side of the road (ft) All Speeds As highlighted in Table 9, the minimum width of traveled way (paved width) on Stanley Avenue should be 2 feet. This value is the same with or without the project since the existing daily traffic volume is greater than 4 vehicles per day. From the parcel lines shown in the Butte County Online GIS program, there should be available right ofway to widen Stanley Avenue to meet AASHTO recommendations. This improvement may, however, restrict the informal parking that currently occurs on the shoulders along Stanley Avenue. The residential lots fronting Stanley Avenue are generally large with space to park more than two vehicles off street, therefore prohibiting parking along the widened roadway should not cause any significant parking impacts. Page 11 of 13

93 Traffic Impact Study Leen Subdivision February 2, 218 To provide a safe and efficient roadway with increased traffic, the applicant will provide a proportionate cost sharing contribution for widening of the pavement section on Stanley Avenue to a 2 foot width from Dayton Road to the project entry point. If the County requests the applicant to physically construct widening improvements in an dollar amount equal to the proportionate share, in lieu of paying the fee, it is our recommendation that the widen begin at Dayton Road and move east to the extent possible with the fee amount. The greatest widening benefit will be realized where traffic volumes are the highest, which is closest to Dayton Road. With proportionate cost sharing for the widening, or by constructing equal value widening improvements, the project will offset/mitigate its impacts of increased traffic related to the width of Stanley Avenue. The California Manual on Uniform Traffic Control Devices (CA MUTCD) states that Center line markings should be placed on all rural arterials and collectors that have a traveled way of 18 feet or more in width and an ADT of 3, vehicles per day or greater. Center line markings should also be placed on other traveled ways where an engineering study indicates such a need. The ADT on Stanley Avenue is well under 3, vehicles per day (622 ADT with the project) and we did not identify any special circumstances (horizontal or vertical curves, unusual conditions, etc.), therefore centerline striping is not justified at this time. CONCLUSIONS & RECOMMENDATIONS The following is a list of our key findings and recommendations: Proposed Project: The project is a 21 unit single family detached housing subdivision. The project site is generally located on the south side of Stanley Avenue about 1,5 feet east of the Dayton Road / Stanley Avenue intersection in Butte County, CA. Project Trips: The Leen Subdivision project is anticipated to generate 198 Daily trips, 16 AM peak hour trips, and 21 PM peak hour trips. Project Access: One access point is proposed for the project, located on Stanley Avenue, as shown on Figure 2. The access point is proposed as a full access intersection allowing for all possible movements with side street stop control. Existing Level of Service: All study intersections and roadway segments currently operate at acceptable level of service conditions (LOS B or better) during the AM and PM peak hours. Existing Plus Project Level of Service: With the addition of project traffic, all study intersections and roadway segments are projected to continue operating at acceptable LOS conditions (LOS B or better) under the Existing Plus Project conditions during both the AM and PM peak hours. The project would have no notable operational impacts on local intersections or roadway segments. Page 12 of 13

94 Traffic Impact Study Leen Subdivision February 2, 218 Summary of Proposed Improvements: To provide a safe and efficient roadway cross section on Stanley Avenue with increased traffic, the applicant will provide a proportionate cost sharing contribution for widening of the pavement section to a 2 foot width from Dayton Road to the project entry point. If the County requests the applicant to physically construct widening improvements in an dollar amount equal to the proportionate share, in lieu of paying the fee, it is our recommendation that the widen begin at Dayton Road and move east to the extent possible with the fee amount. The greatest widening benefit will be realized where traffic volumes are the highest, which is closest to Dayton Road. With proportionate cost sharing for the widening, or by constructing equal value widening improvements, the project will offset/mitigate its impacts of increased traffic related to the width of Stanley Avenue.
