Home My WebLink AboutAR Traffic Study - Traffex AVANA RIDGE APARTMENTS TRAFFIC IMPACT ANALYSIS CITY OF RENTON Prepared for Avana Ridge, LLC 9675 SE 36th St Suite 105 Mercer Island, WA 98040 PPrreeppaarreedd bbyy 11410 N.E. 124th St., #590 Kirkland, Washington 98034 Telephone: 425.522.4118 December 21, 2015 Mr. Justin Lagers December 21, 2015 Avana Ridge, LLC 9675 SE 36th St. Suite 105 Mercer Island, WA 98040 Re: Avana Ridge Apartments – City of Renton Traffic Impact Analysis Dear Mr. Lagers: We are pleased to submit this traffic impact analysis (TIA) for the proposed Avana Ridge Apartments consisting of 74 apartment residential units. The proposed project is located in the triangular area bordered by SR 515, Benson Rd S and SE 172nd St. in the City of Renton. Access to the site is via proposed driveways to SE 172nd St. and Benson Rd. South. This TIA has been prepared per City of Renton guidelines and notes from the pre-application meeting. PROJECT DESCRIPTION Figure 1 is a vicinity map showing the location of the site and the surrounding major street network. Figure 2 is the preliminary site plan of the proposed 74 unit apartment complex. Vehicle access is provided by driveways to SE 172nd St. and Benson Rd. South. The anticipated horizon year for development is 2017. TRIP GENERATION The 74 units in the proposed Avana Ridge Apartments are expected to generate the vehicular trips during an average weekday and during the street traffic peak hours as shown in the following table: Avana Ridge, LLC Page 3 TRIP GENERATION FOR 74 UNIT AVANA RIDGE APARTMENTS Time Period Trip Rate Trips Entering Trips Exiting Total Average Weekday 6.65 246 50% 246 50% 492 AM Peak Hour 0.51 8 20% 30 80% 38 PM Peak Hour 0.62 30 65% 16 35% 46 A vehicle trip is defined as a single or one direction vehicle movement with either the origin or destination (exiting or entering) inside the study site. The trip generation is calculated using the average trip rates in the Institute of Transportation Engineers (ITE) Trip Generation, Ninth Edition, for Apartment (ITE Land Use Code 220). These trip generation values account for all site trips made by all vehicles for all purposes, including resident, visitor, and service and delivery vehicle trips. TRIP DISTRIBUTION AND ASSIGNMENT Figures 3 and 4 show the AM and PM peak hour site generated traffic volumes and distribution for the Avana Ridge Apartments project. The trip distribution is based on existing traffic volume count patterns, the characteristics of the street network, the location of likely trip origins and destinations (employment, shopping, social and recreational opportunities), expected travel times and previous traffic studies. EXISTING PHYSICAL CONDITIONS Street Facilities The streets in the study area are classified per the City of Renton Comprehensive Plan as follows: Benson Dr. S. (SR 515) Principal Arterial Benson Rd. S (108th Ave SE) Minor Arterial SE 172nd St. Commercial Mixed Use Frontage on SE 172nd St. has shoulders with no curb, gutter, landscape strip or sidewalks. Frontage on SR 515 has curb, gutter and sidewalk. Frontage on Benson Rd. has curb and partial sidewalk sections. Figure 5 shows the number of lanes and traffic control at the study intersections and posted speed limit. Avana Ridge, LLC Page 4 Sight Distance Sight distance requirements are met at the site access driveway onto SE 172nd St. and also, with vegetation trimming within the street right of way, at the site access driveway to Benson Rd. South. SE 172nd St. has a posted speed limit of 25 mph. Per American Association of State Highway and Transportation Officials (AASHTO) requirements, a design speed of 25 mph requires a stopping sight distance (SSD) of 155 feet and an intersection sight distance (ISD) of 240 ft. (for a vehicle turning right from the side street), and 280 ft (for a vehicle turning left from the side street). The SSD and ISD is >400 ft. to the west and all the way to the 108th Ave. SE intersection to the east. Benson Rd. S has a posted speed limit of 35 mph. Per AASHTO requirements, a design speed of 35 mph requires a stopping sight distance (SSD) of 250 ft and an intersection sight distance (ISD) of 335 ft. (for a vehicle turning right from the side street), and 390 ft. (for a vehicle turning left from the side street). The SSD and ISD are estimated to be 360 ft. to the north with vegetation trimming within the ROW. The ESD and ISD to the south are all the way to the Benson Dr. S (SR 515) intersection. EXISTING TRAFFIC CONDITIONS Traffic Volumes Figures 6 and 7 show the existing AM and PM peak hour traffic volumes at the study intersections. Traffic volume turning movement counts were conducted on September 7th and 24th, 2015 at the study intersections and are included in the technical appendix. Per the City of Renton Policy Guidelines for Traffic Impact Analysis for New Development intersections and road segments that experience an increase of 5% in traffic volumes require analysis. Accident History The latest three year accident history for the study intersections and streets in the study area was obtained from WSDOT and are included in the technical appendix. There were a total of 4 accidents recorded at the 108th Ave SE/SE 172nd intersection, 2 accidents at the Benson Rd. S/108th Ave SE intersection, 5 accidents on 108th Ave SE , 2 accidents on Benson Rd. S and 1 accident on SE 172nd Street. Six of the accidents were due to inattention, 3 were due to following to close, and the rest were due to other miscellaneous driver errors and 1 operating a vehicle under the influence. Neither our field observations nor the accident history identified any obvious safety deficiencies. Avana Ridge, LLC Page 5 Level of Service Analysis LOS is a qualitative measure describing operational conditions within a traffic flow, and the perception of these conditions by drivers or passengers. These conditions include factors such as speed, delay, travel time, freedom to maneuver, traffic interruptions, comfort, convenience, and safety. Levels of service are given letter designations, from A to F, with LOS A representing the best operating conditions (free flow, little delay) and LOS F the worst (congestion, long delays). Generally, LOS A and B are high, LOS C and D are moderate and LOS E and F are low. Table 1 shows calculated levels of service (LOS) for existing and future conditions at the study intersection. The LOS’s were calculated using the procedures in the Transportation Research Board Highway Capacity Manual. The LOS shown indicates overall intersection operation. At intersections, LOS is determined by the calculated average control delay per vehicle. The LOS and corresponding average control delay in seconds are as follows: TYPE OF INTERSECTION A B C D E F Signalized < 10.0 >10.0 and <20.0 >20.0 and <35.0 >35.0 and <55.0 >55.0 and <80.0 >80. 0 Stop Sign Control <10. 0 >10 and <15 >15 and <25 >25 and <35 >35 and <50 >50 LOS calculation worksheets are included in the technical appendix. The study intersections are calculated to operate at an acceptable LOS for existing and future conditions per City of Renton standards. FUTURE TRAFFIC CONDITIONS WITHOUT THE PROJECT Figures 6 and 7 show projected future AM and PM peak hour traffic volumes without the project. These volumes include the existing traffic volumes, plus background traffic growth, plus pipeline project volumes from the Fieldbrook Apartments development. An annual growth factor of 2% per year was assumed per City of Renton request. The 2% per year growth factor over a two year period (totaling 4%) was added to 2015 existing traffic volumes. In addition to the growth factor, trips generated by the nearby pipeline project Fieldbrook Apartments were added to future volumes. Fieldbrook Apartments consists of 162 apartment units. Trip generation was obtained from the Fieldbrook Apartments TIA and is shown as pipeline volumes in Figures 6 and 7. Avana Ridge, LLC Page 6 FUTURE TRAFFIC CONDITIONS WITH PROJECT Figures 6 and 7 show the projected future AM and PM peak hour traffic volumes with the proposed project. The site generated traffic volumes were added to the 2017 future (without project) traffic volumes. Tables 1 and 2 show that the AM and PM peak hour calculated LOS for future conditions with and without the project meet the City of Renton intersection standards of LOS D or better. Signal Warrant Analysis Traffic signal warrants for new signals are contained in the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) FHWA. The warrants are as follows: Warrant Description 1 Eight Hour Vehicular Volume 2 Four Hour Vehicular Volumes 3 Peak Hour 4 Pedestrian Volume 5 School Crossings 6 Coordinated Signal System 7 Crash Experience 8 Roadway Network The primary warrant used by agencies in determining whether a signal is needed is warrant 1 (Conditions A and B). These warrants are satisfied when, for each of any 8 hours of an average day, certain minimum traffic volumes exist on the major and minor approaches to an intersection. Warrant 1 (Condition A) is met when the major roadway has at least 500 vehicles per hour (total of both approaches, 1 lane in each direction) and 150 vehicles per hour on the minor roadway for the same 8 hours. Warrant 1 (Condition B) is met when the major roadway has at least 750 vehicles per hour (total of approaches, 1 lane in each direction) and 75 vehicles per hour on the minor roadway for the same 8 hours. The City has requested that the traffic volumes at the 108th Ave SE/SE 172nd St. intersection be examined to determine if traffic signal warrants are met. The 2017 horizon year projected PM peak hour traffic volumes at the intersection is 717 vehicles per hour on 108th Ave. SE (total of both approaches) and 118 vehicles per hour on SE 172nd Street. Typically, traffic volumes for the 8th highest hour are 60% of the PM peak hour traffic volumes. Therefore, the 8th highest hour traffic volume on 108th Ave. SE is 430 vehicles per hour and on SE 172nd St. 71 vehicles per hour. Avana Ridge, LLC Page 7 The table below presents the traffic signal warrant analysis for warrant 1 (Condition A and Condition B) for future with project traffic volume conditions. 228th Ave. NE/NE 14th St. Traffic Signal Warrant 1 Movement Projected 8th Highest Hour Warrant 1A Required Min. Vol. Warrant 1A Met? Warrant 1B Required Min. Vol. Warrant 1B Met? Major 430 500 750 Minor 71 150 No 75 No The 2017 future projected traffic volumes are not anticipated to exceed the minimum traffic volumes for warrant 1A and warrant 1B on the major street (108th Ave. SE) nor on the minor street (SE 172nd St.) for eight hours on an average day. Therefore traffic signal warrant is not met and a signal is not warranted. TRAFFIC MITIGATION TRAFFIC MITIGATION REQUIREMENTS The City of Renton requires a Transportation Mitigation Fee payment of $1454.20 per apartment unit. The estimated Transportation Mitigation Fee for the 74 units of the Avana Ridge Apartments is estimated to be $107,611 (74 units x $1454.20 per unit). Frontage improvements to City of Renton standards are required on SE 172nd St. including curb, gutter, landscape strip, sidewalk and street lights. Landscape strip, sidewalk and street lights are required on Benson Rd. S. frontage. As shown on the site plan, the northern portion of the frontage on SR 515 will be improved to Renton standards with new landscape strip, sidewalk and street lights. Due to extreme slopes, a variance is requested for the southern portion of SR 515 frontage to be left as is with existing curb, gutter and sidewalk with no landscape strip. The combination of new and existing street lights on SR 515 will be designed to meet City of Renton lighting requirements. Avana Ridge, LLC Page 8 SUMMARY, CONCLUSIONS AND RECOMMENDATIONS We recommend that the Avana Ridge Apartments be constructed as shown on the site plan with the following traffic impact mitigation measures: · Construct frontage improvements. · Contribute the estimated Transportation Mitigation fee of approximately $107,611 to City of Renton. No other traffic mitigation should be necessary. If you have any questions, please call 425-522-4118. You may also contact us via e-mail at vince@nwtraffex.com or larry@nwtraffex.com.
