Home My WebLink AboutDune Palms Traffic Study ReportDUNE PALMS ROAD LOW WATER CROSSING REPLACEMENT PROJECT CITY OF LA QUINTA RIVERSIDE COUNTY, CALIFORNIA Traffic Analysis Report October 2015 Prepared for: City of La Quinta Federal Project Number BLRKS-5433(014) Prepared by: Page 1 1.Introduction Project Purpose The purpose of the project is to replace the existing low-water crossing spanning the Coachella Valley Storm Water Channel (CVSC) at Dune Palms Road with an all-weather access. The proposed improvements will accomplish the following in the project area: 1.Provide safe access across the CVSC (Whitewater River) during all-weather events 2.Provide reliable route for emergency vehicles, motorists, pedestrians, and bicyclists 3.Achieve the City’s General Plan goals for the corridor Project Need Dune Palms Road serves a vital access for emergency services within the project area, as well as for La Quinta High, John Glenn Middle and Amelia Earhart Elementary Schools. It also provides connectivity of the city residential development north of the Channel with the Highway 111 commercial corridor located south of the CVSC. (Please see attached Vicinity and Location Maps) The CVSC conveys storm water runoff from the surrounding mountains as well as developed areas within the Coachella Valley. The elevation of the existing Dune Palms Road low-water crossing causes it to flood during minor rain events (2-year frequency) and results in full street closure and detour of both vehicle and pedestrian traffic. In the interest of public health and safety, and in response to community concerns regarding frequent closures of the low-water crossing, the City of La Quinta has determined that replacement of the low-water crossing with a new bridge is needed to ensure that all-weather access is maintained. The Dune Palms Road low-water crossing is the last remaining low-water crossing of the CVSC within the City. Project Description Existing Conditions. The existing roadway crosses the CVSWC at the channel grade. The roadway width is 68 feet at the crossing, and consists of one northbound and two southbound through lanes, eight foot wide walkway area along the western edge, and an eight foot shoulder along the eastern edge of the road; and no median. The existing roadway approach south of the crossing consists of one northbound and two southbound through lanes. The northern roadway approach consists of one through lanes in each direction. The transition from one to two lanes in the southbound direction occurs at the midpoint of the channel crossing. Dune Palms Road approximately one-quarter mile north of the channel low- water crossing and just south of the project limits is a four lane roadway with a median. The roadway section just north of the crossing will be widened as part of an approved City project. The project was originally approved with a Mitigated Negative Declaration under CEQA in April 2010. The PS&E for the project was 90% complete. Page 2 Proposed Improvements. The project proposes to remove the existing low-water crossing of Dune Palms Road at the CVSC in the City of La Quinta, Riverside County. The crossing will be replaced with a 480 feet long and 86 feet wide four-span bridge. The bridge typical section consists of six-foot sidewalk on both sides of the bridge, two (2) eight-foot outside shoulders also serving as bike/golf cart lanes, a 10 foot raised median, two (2) eleven-foot travel lanes, and two (2) twelve-foot travel lanes. The proposed configuration will be consistent with the existing four lane roadway section to the south, and the City’s current improvement project to the north (City Project Number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements will include a reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the project’s construction limits will be extended to 239 feet of Highway 111. On the north side of the bridge, the project construction limits will be extended to include a vacant lot immediately north of the project limits. The vacant lot is owned by the City and will be offered by the City in the bidding documents to be used for storage and construction staging by the contractor for the construction of this project. As a part of the bridge construction, concrete slope protection will be installed along the north side of the channel. Additionally, minor removal and replacement of slope protection will be required on the south side of channel west of the proposed bridge and extension of slope protection approximately 300 feet downstream of the proposed bridge. The slope protection is needed for scour countermeasures as required by the Coachella Valley Water District (CVWD), who is responsible for the operations and maintenance of the CVSC. As a result of the proposed cast-in-place drilled shaft bridge construction, scour protection within the bottom of the channel will not be required. The project will also include the following additional improvements: • Railing Architectural treatment. The bridge design will incorporate railing architectural treatment as required by the City’s standard design. • Integration of a regional Bike/Pedestrian/NEV corridor (CV Link). The Coachella Valley Association of Governments (CVAG) and the communities within the Coachella Valley are working together on the implementation of a regional Bike/Pedestrian/NEV corridor (CV Link) along Whitewater River and Coachella Valley Storm Water Channel. The project design will be consistent with these plans by allowing for the integration of a trail under crossing within the southern slope protection, which also includes a trail connector to the pedestrian and bike facilities proposed along Dune Palms Road in the project area. • Utility Relocation. The project will also require utility relocations for overhead electrical distribution lines (Imperial Irrigation District facility), adjustment to both water valve can and lids and the manhole covers, minor 12” ductile iron pipe water main relocations at each bridge abutment, and relocation of both a 12” and 18” sewer line at the northern bridge abutment. Page 3 Right-of-Way Requirements. The project will require right-of-way acquisition on the northeast and southeast corners of the proposed bridge. The existing development at the northeast corner of the proposed bridge consists of a Mobile Home Park with one single family home. Some of the mobile homes adjacent to the Dune Palms Road are encroaching within the street right of way. The project may require the acquisition of the single-family residence and relocation of two mobile homes residents. The project will be designed to avoid and minimize relocation impacts of the mobile homes. At the southeast corner of the crossing, the existing parcel is currently an undeveloped commercial parcel. Acquisition for the vacant parcel will consist of a strip taking parallel with Dune Palms Road. Construction of Temporary Bypass. The existing roadway will be modified to construct a temporary bypass road. The temporary bypass will allow for staged construction of the bridge, and maintaining vehicle and pedestrian access at all times. Temporary and short term access impact may occur during construction, and will require coordination with property owners, the public, and other stakeholders. Traffic Study This report provides traffic analysis of Dune Palms Road at the project location and at the adjacent intersections of Dune Palms at Highway 111 and Dune Palms Road at Westward Ho Drive/Blackhawk Way. The analysis includes existing and future conditions with and without the project. Although traffic operations in the vicinity of the crossing are degraded when Dune Palms Road is closed due to weather events, and traffic is diverted to nearby roads and intersections, this traffic study focuses on the adjacent intersections since they are directly affected by the improvements on Dune Palms Road. Page 4 2.Study Area The study area for this project includes the segment of Dune Palms Road between Highway 111 and Westward Ho Drive/Blackhawk Way. The study also includes the two signalized intersections on either side of this segment of Dune Palms Road that is being reconstructed. The study intersections and segment are listed below and shown in Figure 1. 1.Dune Palms Road and Westward Ho Drive/Blackhawk Way 2.Dune Palms Road and Highway 111 3.Study Scenarios This report presents the analysis of the following three study scenarios: x Existing Conditions – operation of the intersections and roadway segment with existing traffic volumes x Future 2040 No-Build Conditions – operation of the intersections and roadway segment with future traffic volumes and existing roadway geometrics (i.e. number of lanes) x Future 2040 Build Conditions – operation of the intersections and roadway segment with future traffic volumes and proposed roadway reconstruction geometrics Figure 1: Dune Palms Road Project Location and Study Area Page 5 4.Study Analysis Methodology Street system operating conditions are typically described in terms of “level of service.” Level of service is a report-card scale used to indicate the quality of traffic flow on roadway segments and at intersections. Level of service (LOS) ranges from LOS A (free flow, little congestion) to LOS F (forced flow, extreme congestion). A more detailed description of the concepts described in this section is provided in Appendix A of this document. The following methods are used in this study. Roadway Segment Capacity Analysis The City of La Quinta has published daily traffic volume standards for roadways within its jurisdiction in the Circulation Element of the General Plan, adopted by the City on 2/19/2013. To determine service levels on study area roadway segments, we compared the appropriate average daily traffic thresholds for level of service to the daily capacity of the study area roadway segments, and the existing and future volumes in the study area. The thresholds for determining level of service used in this analysis are shown in Appendix A. Intersection Capacity Analysis The analysis of peak hour intersection performance was conducted using the SYNCHRO analysis software program, which uses methodologies defined in the 2000 Highway Capacity Manual (HCM) to calculate results. Level of service (LOS) for intersections is determined by control delay. Control delay is defined as the total elapsed time from when a vehicle stops at the end of a queue to the time the vehicle departs from the stop line. The total elapsed time includes the time required for the vehicle to travel from the last-in-queue position to the first-in-queue position, including deceleration of vehicles from free-flow speed to the speed of vehicles in the queue. The HCM analysis methodology for evaluating signalized intersections is based on the “operational analysis” procedure. This technique uses 1,900 passenger cars per hour of green per lane (pcphgpl) as the maximum saturation flow of a single lane at an intersection. This saturation flow rate is adjusted to account for lane width, on-street parking, conflicting pedestrian flow, traffic composition, (e.g., the percentage of vehicles that are trucks) and shared lane movements (e.g., through and right-turn movements from the same lane). Average control delay is calculated by taking a volume-weighted average of all the delays for all vehicles entering the intersection. The intersection analysis focuses on the intersection peak hour during a weekday. Appendix A lists the HCM delay/LOS criteria for signalized intersections. General Plan’s Concept LOS The City of La Quinta has established LOS D as the threshold for acceptable operating conditions; therefore all roadways and intersections operating at LOS D or better are acceptable. Roadways and intersections that operate at LOS E or F are considered deficient. Page 6 5.Analysis Results 5.1 Existing Conditions Traffic Volumes Existing roadway segment (24-hour) counts with vehicle classifications were collected on Thursday, August 6, 2015. Existing turning movement counts were collected on the same day for the AM (7:00- 9:00a.m.) and PM (4:00-6:00p.m.) peak periods at the study intersections. The City of La Quinta applies a seasonal adjustment factor to traffic volumes collected outside of the calendar window of January 2 through March 31. Per the City’s Engineering Bulletin #06-13 (see Appendix E), traffic volumes were increased by 20% as an adjustment for traffic counts collected during the month of August.Figure 2 shows the adjusted existing traffic volumes collected at each study intersection. Intersection Conditions Table 1 summarizes the intersection LOS and delay for the AM and PM peak hours under the existing conditions. As shown in the table, all study intersections are operating at LOS C or better in both the AM and PM peak periods.

Regional travel forecasting models were employed and future build-out of the City was determined to be at 2035. Build-out in the City of La Quinta represents the maximum fulfilled land use and generated traffic volumes on the local circulation network. Therefore, for the purposes of the future project 2040 analysis, the build-out traffic volumes were assumed to be the same as the 2035 volumes noted the General Plan. The General Plan includes future roadway segment volumes for Dune Palms Road as well as peak hour intersection turn movement volumes for the two study intersections.Figure 3 shows the future traffic volumes for the roadway segment and at each study intersection. Intersection Conditions Table 3 summarizes the intersection LOS and delay for the AM and PM peak hours under the future no- build conditions. The analysis and conditions reported are according to the General Plan. As shown in the table, all study intersections are operating at LOS D or better in both the AM and PM peak periods.

With the improvements to Dune Palms Road, the segment level of service improves in the future.Table 8 shows the summary of the peak hour intersection conditions for each scenario. All of the intersections and roadway segment operate at acceptable levels currently and in the future, with and without the project per the General Plan. The future intersection LOS at the study intersections are not affected by the project improvements associated with the Dune Palms Road Bridge project, rather the LOS is shown to degrade due to the increase in traffic volumes. It is the conclusion of this report that the project and the proposed project elements will not result in further degradation of the roadway segment or intersection LOS for those elements analyzed herein, and that the degradation of the LOS noted for the study intersections is due to future increases in traffic volumes. All intersections and roadway segment will operate at acceptable levels of service in the future.

Signalized Intersection Level of Service Highway Capacity Manual Operational Analysis Method The operational analysis method for evaluation of signalized intersections presented in the 2000 Highway Capacity Manual (Transportation Research Board Special Report 209) defines level of service in terms of delay, or more specifically, control stopped delay per vehicle. Delay is a measure of driver and/or passenger discomfort, frustration, fuel consumption, and lost travel time. Control Stopped Delay Per Vehicle (seconds) Level of Service (LOS) Characteristics <10 LOS A describes operations with very low delay. This occurs when progression is extremely favorable, and most vehicles do not stop at all. Short cycle lengths may also contribute to low delay. >10 – 20 LOS B describes operations with generally good progression and/or short cycle lengths. More vehicles stop than for LOS A, causing higher levels of average delay. >20 – 35 LOS C describes operations with higher delays, which may result from fair progression and/or longer cycle lengths. Individual cycle failures may begin to appear at this level. The number of vehicles stopping is significant at this level, although many still pass through the intersection without stopping. >35 – 55 LOS D describes operations with high delay, resulting from some combination of unfavorable progression, long cycle lengths, or high volumes. The influence of congestion becomes more noticeable, and individual cycle failures are noticeable. >55 – 80 LOS E is considered to be the limit of acceptable delay. Individual cycle failures are frequent occurrences. >80 LOS F describes a condition of excessively high delay, considered unacceptable to most drivers. This condition often occurs when arrival flow rates exceed the capacity of the intersection. Poor progression and long cycle lengths may also be major contributing causes to such delay.
