PROJECT DESCRIPTION The Brackett's Corner residential development is located along the west side of 80th Avenue W, south of 212th Street SW. A site vicinity map that shows the study intersection is included in Figure 1. The development will consist of 14 single family dwelling units. The development is proposed to be constructed in one phase with build -out and occupancy scheduled for the year 2016. The site currently has a total of 5,346 square feet (sf) of general office and one single family dwelling which the development will receive credit for. The development is proposing to have two access points to 8e Avenue W. There are currently two curb -cuts on 212th Street SW which will be removed with the redevelopment and there are two on 80th Avenue W which will be relocated with the redevelopment. 2. TRIP GENERATION The daily, AM peak -hour and PM peak -hour trips anticipated to be generated by the proposed development were estimated by trip generation data contained in the ITE Trip Generation Manual, 9th Edition (2012). The ITE land use code 210, Single Family Dwelling and LUC 710, General Office, were used for the proposed development. The proposed development will generate fewer trips during the AM peak -hour than the PM peak -hour; this confirms that the PM peak -hour is the critical commuter peak for the level of service and channelization analysis. Brackett's Corner will be receiving credit for the removal of the single-family house already on site along with 5,346 sf. The development will generate 64.79 ADT with 1.41 AM peak -hour trips (4.90 inbound/6.31 outbound) and 5.03 PM peak - hour trips (6.84 inbound/ -1.81 outbound). A Trip Generation summary has been included in Table 1. Table 1: Trip Generation Summary The trip generation calculations are included in the attachments. Gibson Traffic Consultants, Inc.

TRIP DISTRIBUTION The distribution of trips generated by the Brackett's Corner development is based on the existing turning niovemnents at the study intersections located around the development. Although there will be two accesses on 80th, just the northern access was loaded with trips to simulate a worst case scenario. The trip distribution ror the development assumes that 40% of the site traffic will travel to and from the north on 80th Avenue W and 60% to and from the south on 80th Avenue W. The forty percent would spilt with twenty percent heading west on 212th Street SW and twenty percent heading east, on 212th Street SW. The distributions of AM and PM peak -hour trips generated by the development are shown in Figure 2 and 3 respectively. Gibson Traffic Consultants, Inc.

SITE ACCESS ROADWAY/DRIVEWAYS AND SAFETY The development is proposing to have two access points to 80th Avenue W, one between the two northern accesses on the opposite side of 80th Avenue W for private condos and one directly across from the third access point traveling south for the private condos. The northern access will have 61 feet of corner to corner clearance from 212St Street SW. There will be about 90 feet between the two site accesses. The southern access will have about 161 feet of corner to corner clearance from 213th Street SW. There are currently two curb -cuts along 212th Avenue W which will be removed with the development. The frontage of the development currently has curb, gutter, and sidewalk along the north side and a rolled curb and sidewalk along the east side. 4.1 Sight Distance Requirements Sight distance analysis was performed at the proposed site access point according to current AASHTO standards. The entering sight distance was measured from 10 feet back of the pavement from an eye height of 3.5 feet to and eye height of 3.5 feet. The stopping sight distance was measured from an eye height of 3.5 feet to an object height of 2 feet. On 80th Street W the sight distance is based on a posted speed of 25 mph. The required entering sight distance is 280 feet and the required stopping sight distance is 155 feet per AASHTO requirements. There is over 300 feet of stopping and entering sight distance to the north and south of the proposed accesses. The sight distance is met for both accesses. 4.2 Channelization Warrants The WSDOT Design Manual Exhibit 1310-15a, Left -Turn Lane Guidelines show that left -turn channelization is not required at the proposed access as the intersection Design Hour Volume does not meet the required minimum number of vehicles. Also, the WSDOT Design Manual Exhibit 1310-19, Right -Turn Lane Guidelines show that right -turn channelization, either a pocket or lane, is not required until there are 20 right -turning vehicles. The access is not anticipated to have 20 right -turning vehicles during the PM peak -hour and therefore the accesses to the Brackett's Corner would not warrant right -turn channelization. 4.3 Access Separation The development is proposing to have two access points to 80th Avenue W just south of the existing access from private condos located on the east side of 801h Avenue W. The northern access will have about 61 feet of corner to corner clearance from 212th Street SW. There is approximately 90 feet of clearance between the two access points. The southern access will have 161 feet of corner to corner clearance from 213th Street SW located to the south of the development. The proposed access improves the existing access where vehicles are backing out on to 80th Avenue W. Gibson Traffic Consultants, Inc. December 2015 info@gibsontraffic.com 6 GTC #15-260 Brackett's Corner Traffic Impact Analysis 4.4 Access Level of Service Analysis The analysis of the study intersections and site access has been performed using the Synchro 9. 0, Build 903 software. Traffic congestion is generally measured in terms of level of service (LOS). In accordance with the 2010 Highway Capacity Manual (RCM, road facilities and intersections are rated between LOS A and LOS F, with LOS A being free flow and LOS F being forced flow or over -capacity conditions. The level of service at signalized and all -way stop -controlled intersections is measured in terms of average delay per vehicle in seconds. The level of service for two-way stop -controlled intersections is determined by the worst case of all the calculated lane groups at the intersection. A summary of the level of service criteria has been included in Table 2. Table 2: Level of Service Criteria for Intersections Intersection Control Delay Level of 1 Expected Seconds ger. Vehicle Service Delay Unsignalized Signalized Intersections I Intersections A Little/No Delay <10 <10 B Short Delays >10 and <15 >10 and <20 C Average Delays >15 and <25 >20 and <35 D Long Delays >25 and <35 >35 and <55 E Very Long Delays >35 and <50 >55 and <80 F Extreme Delays2 >50 >80 Source: Highway Capacity Manual 2010. LOS A: Free-flow traffic conditions, with minimal delay to stopped vehicles (no vehicle is delayed longer than one cycle at signalized intersection). LOS B: Generally stable traffic flow conditions. LOS C: Occasional back-ups may develop, but delay to vehicles is short term and still tolerable. LOS D: During short periods of the peak hour, delays to approaching vehicles may be substantial but are tolerable during times of less demand (i.e. vehicles delayed one cycle or less at signal). LOS E: Intersections operate at or near capacity, with long queues developing on all approaches and long delays. LOS F: Jammed conditions on all approaches with excessively long delays and vehicles unable to move at times. 2 When demand volume exceeds the capacity of the lane, extreme delays will be encountered with queuing which may cause severe congestion affecting other traffic movements in the intersection. Gibson Traffic Consultants, Inc. December 2015 info@gibsontraffic.com 7 GTC #15-260 Brackett's Corner Traffic Impact Atialysis Per the November 2009 Comprehensive Transportation Plan; the acceptable level of service for City of Edmonds intersections is LOS D or better for arterials and LOS C or better for collectors. The level of service analysis shows that the access to 80th Avenue W will operate at LOS A with 8.8 seconds of delay even with all of the development traffic loaded on the single access. 4.5 Collision Summary The latest 5 -year collision history from January 1, 2010 through Available 2015 was obtained from WSDOT. There were a total of 8 collisions within 100 feet of the intersection of 212th Street SW and 80th Avenue W in the 5 -year reporting period within the study area. The data is summarized in Table 3 below. Table 3: 5 -Year Collision Rate and Frequency — January 1, 2010 to Available 2015 ........ ,.am�� _........ ...._.

The collision rate at the primary study intersections should therefore be considered acceptable since the collision rate is below the state average. Only 1 of the 8 collisions identified 80th Avenue W as the primary roadway where the collision occurred. The collision occurred outside the shoulder of the primary roadway and the vehicle struck an object. None of the 8 collisions involved a fatality as the most severe injury type. 3 The Average Daily Traffic (ADT) assumes a design K -value of 10. Gibson Traffic Consultants, Inc.

TRAFFIC VOLUMES & LEVEL OF SERVICE Existing PM peak -hour counts were collected at the off-site study intersection: 212th Street SW at 801h Avenue W These counts were performed by Traffic Data Gathering (TDG) on December 1, 2015. The existing turning movements are shown in Figure 4. Due to how close the change of year was, this report will state the future year as 2017/2018. A full two years of growth was still added from December of 2015 to December of 2017. The 2017/2018 baseline traffic volumes were determined using a 2% annually compounding growth rate to account for other developments in the site vicinity. The 2017/2018 baseline turning movements are shown in Figure 5. The 2017/2018 future with development traffic volumes were calculated by adding the development's trips to the 2017/2018 baseline traffic volumes after zeroing out any trips coming to or from the site. The 2017/2018 future with development turning movements are shown in Figure 6. The 2022/2023 baseline turning movements are shown in Figure 7. The 2022/2023 future with development traffic volumes were calculated by adding the development's trips to the 2022/2023 baseline traffic volumes after zeroing out any trips coming to or from the site. The 2022/2023 future with development turning movements are shown in Figure 8. The traffic volume calculations are included in the attachments. Gibson Traffic Consultants, Inc.

LEVEL OF SERVICE ANALYSIS The future with development level of service analysis has been performed for the additional 5 new PM peak -hour trips that would impact the study intersections. The development's trips were added to the baseline turning movements to determine the future with development turning movements. Counts were collected by GTC staff at the two driveways opposite of the developments north driveway to check for any turning conflicts. The driveway northern driveway of the two had inbound traffic, but no outbound while the southern of the two had no inbound or outbound traffic during the PM peak -hour. Due to this, both driveways will operate at a LOS A with 0 seconds of delay. The intersection of 212`h Street SW at 80th Ave W will remain at LOS D but the delay will increase to 27.5 sec with the development with two years of growth and 28.2 sec with the development in seven years. For this intersection, for the seven years of growth, a Peak 1.1our Factor of 0.92 was used to account for the traffic growth at this intersection this far in the future. The intersection of the existing/future driveway and 80th Avenue W will remain at LOS A with the delay increasing to 8.8 sec in 2017/2018 and 2022/2023. The 2017/2018 & 2022/2023 Future with development level of service has been shown in Table 4. All of the study intersections will remain at acceptable LOS per city standards with the development and background traffic forecasts for the 2022/2023 concurrency forecast year.

The development is proposing to have two access points to 80th Avenue W which will have adequate sight distance and will operate at an acceptable level of service. The development is anticipated to generate 64.79 new average daily trips with 5.03 PM peak -hour trips (6.84 inbound/ -1.81 outbound). The development will have traffic mitigation fees of $6,231.64; based on the methodology outlined in Table 4 of the City of Edmonds Traffic Impact Analysis Guidelines. The development will not have a significant impact on the adjacent intersection. Also, based on the low volume utilizing the accesses, the existing low collision history, and low conflicting volumes from the accesses on the east side of 80th Avenue W the accesses would operate safely in the proposed site layout configuration.

For multilane, high speed highways (posted speed 45 mph or above), use the right -lane pez hour approach volume (through + right turn). [2] When all three of the following conditions are met, reduce the right -turn DDHV by 20: The posted speed is 45 mph or less, the right -turn volume is greater than 40 VPH, the peak hour approach volume (DDHV) is less than 300 VPH. [3] For right -turn corner design, see Exhibit 1310-11. [4] For right -turn pocket or taper design, see Exhibit 1310-16. [5] For right -turn lane design, see Exhibit 1310-17. " For Multilane, low speed highways (posted speed is less than 45 mph), no right -turn lane taper is required. Based on WSDOT July 2010 Design Manual: Exhibit 1310-19, Page 1310-40. K-2 Site Plan.
