REVISED TRAFFIC SCOPE 2020-01-29Ofc: 1001 Dove St. Suite 260 Newport Beach, CA 92660 Main: 260 E. Baker St. Suite 200 Costa Mesa, CA 92626 urbanxroads.com 12615‐06 Revised Scope.docx January 29, 2020 Mr. Steve Libring City of La Quinta 78‐405 Calle Tampico La Quinta, CA 92253 SUBJECT: REVISED SCOPING AGREEMENT FOR THE WAVE AT CORAL MOUNTAIN REVISED TRAFFIC IMPACT ANALYSIS Dear Mr. Steve Libring: The firm of Urban Crossroads, Inc. is pleased to submit this scoping agreement for The Wave at Coral Mountain (“Project”), which is located on the southwest corner of re‐aligned Madison Street at 58th Avenue, in the City of La Quinta. Proposed development activities within the Specific Plan (west of Madison Street) are based upon the following land use quantities: • Single Family Detached 496 DU • Multifamily Housing (Low‐Rise) 104 DU • Resort Hotel 150 RM • Shopping Center 60 TSF • Wave Pool Facility 12 AC The preliminary land use plan for the proposed Project is shown on Exhibit 1. The average number of attendees per day on a typical weekday as well as a special event day will be discussed in the revised TIA. Our goal is to obtain comments from City of La Quinta staff, to ensure that the traffic impact analysis (TIA) fully addresses the potential impacts of the proposed Project. The remainder of this letter describes the proposed analysis methodology, Project trip generation, and trip distribution on the surrounding roadway network. The following scoping assumptions have been prepared in accordance with the City of La Quinta Traffic Study Guidelines (Engineering Bulletin #06‐13, revised October 3, 2017). Exhibit 2 depicts the location of the proposed project in relation to the existing roadway network. Project access locations are listed below: • Madison Street / Main Access (full access) • South Access / Avenue 60 (full access) • Project Access 1 / Avenue 58 (full access) • Project Access 2 / Avenue 58 (right‐in/right‐out access) • Madison Street / Project Access 3 (right‐in/right‐out access) Mr. Steve Libring City of La Quinta January 29, 2020 Page 2 12615‐06 Revised Scope.docx TRIP GENERATION The Project is anticipated to be constructed in phases, with Phase 1 (2021) including resort (wave pool and hotel uses), 104 attached dwelling units, 26 detached dwelling units, and 10,000 square feet of retail. Project Phase 2 (2023) adds 22,500 square feet of retail. Project Phase 3 (2026) adds 470 detached dwelling units and 22,500 square feet of retail. In accordance with the City of La Quinta’s Engineering Bulletin #06‐13, the Project trip generation rates to be used for the traffic impact analysis will be based on the Institute of Transportation Engineers (ITE) Trip Generation manual, 10th Edition (2017). Trip generation estimates for the Project have been determined by utilizing the published rates for the peak hour of the generator rather than for the peak hour of adjacent street traffic, where possible. Trip generation rates are presented on Tables 1 through 3 for Phase 1 through Project buildout conditions, respectively. ITE trip generation rates for Single Family Detached Residential (Code 210), Multifamily Housing (Code 220), Resort Hotel (Code 330), and Shopping Center (Code 820) are used. The surf pool is a private facility. As indicated in the original approved TIA scope for this Project, trip generation rates for the Wave Pool Facility from the San Diego Association of Governments recreational park (developed) rates appropriately account for this private facility. The project area land uses include a unique mix of commercial retail, resort, recreation and residential uses, so reasonable assumptions regarding internal/pass‐by interactions between these uses are included in the trip generation calculations. The wave pool facility will be utilized by hotel guests, but outside trip generation is also included for things like off‐site lunch, wave pool employees, etc. Area residents and visitors will use the commercial retail area facilities (which typically include merchandise, service station and restaurant land uses). The total internal/pass‐by trip ends have been adjusted in a manner to ensure that no “double counting” occurs before assigning the project trips to the roadway network. As shown on Table 1, Phase 1 of the proposed Project is anticipated to generate a net total of 2,227 external trip‐ends per day on a typical weekday with 114 external vehicles per hour (VPH) during the weekday AM peak hour and 151 external VPH during the weekday PM peak hour. Table 2 shows trip generation for Phase 2 of the proposed Project, which is anticipated to generate a net total of 2,778 external trip‐ends per day on a typical weekday with 123 external vehicles per hour (VPH) during the weekday AM peak hour and 208 external VPH during the weekday PM peak hour. As shown on Table 3, at Project buildout, the site is anticipated to generate a net total of 6,994 external trip‐ends per day on a typical weekday with 447 external vehicles per hour (VPH) during the weekday AM peak hour and 638 external VPH during the weekday PM peak hour. TRIP DISTRIBUTION Trip distribution is the process of identifying the probable destinations, directions or traffic routes that will be utilized by Project traffic. The potential interaction between the planned land uses and surrounding regional access routes are considered to identify the routes where modified project traffic Mr. Steve Libring City of La Quinta January 29, 2020 Page 3 12615‐06 Revised Scope.docx would travel. The trip distribution pattern is heavily influenced by the geographical location of the site, the location of surrounding uses, and the proximity to the arterial and regional freeway system. The trip distribution patterns for the proposed Project residential and resort components are graphically depicted on Exhibit 3. Exhibit 4 shows the trip distribution patterns for the proposed Project shopping center components. The trip distributions have been developed based on RivTAM and local knowledge in the vicinity of the Project site and refined to reflect the roadway network and the surrounding uses in the vicinity of the proposed Project as they exist today and are planned for the future. STUDY AREA The traffic impact study area was defined in conformance with the requirements of Engineering Bulletin #06‐13. Based on this criterion, anticipated trip generation and trip distribution, the following intersections will be evaluated (see Exhibit 2): ID Intersection Location ID Intersection Location 1 Madison Street at Avenue 58 12 Monroe Street at Avenue 58 2 Madison Street at Avenue 56 13 Monroe Street at Airport Boulevard 3 Madison Street at Avenue 54 14 Monroe Street at Avenue 54 4 Madison Street at Avenue 52 15 Monroe Street at Avenue 52 5 Madison Street at Avenue 50 16 Monroe Street at 50th Avenue 6 Jefferson Street at Avenue 54 17 Jackson Street at 58th Avenue 7 Jefferson Street at Avenue 52 18 South Access at Avenue 60 ‐ (Future Intersection) 8 Jefferson Street at Pomelo 19 Madison Street at Main Access‐ (Future Intersection) 9 Jefferson Street at Avenue 50 20 Project Access 1 at Avenue 58‐ (Future Intersection) 10 Madison Street at Avenue 60 21 Project Access 2 at Avenue 58‐ (Future Intersection) 11 Monroe Street at Avenue 60 22 Madison Street at Project Access 3‐ (Future Intersection) In addition, the following roadway segments will be evaluated: Roadway Segment 1 Avenue 58, west of Madison Street 4 Madison Street, south of Airport Boulevard 2 Avenue 58, west of Monroe Street 5 Avenue 60, west of Monroe Street 3 Avenue 58, west of Jackson Street 6 Monroe Street, south of Airport Boulevard TRAFFIC COUNTS Traffic count data were previously taken on August 15th, 2017, April 9th, 2019, May 7th, 2019, and September 9th, 2019 during the AM peak period of 6:00 AM to 8:30 AM and PM peak period of 2:30 PM to 5:30 PM. A 20% increase is applied to counts taken in August, 5% increase is applied to counts taken in April, 10% increase is applied to counts taken in May, and 15% increase is applied to counts taken in September per City of La Quinta’s EB#06‐13. Table 4 shows that the average AM/PM peak hour intersection growth between 2017 and 2019 counts data at selected study area and nearby intersections Mr. Steve Libring City of La Quinta January 29, 2020 Page 4 12615‐06 Revised Scope.docx is approximately 2.66%. The additional 2.66% growth rate is applied to the study area intersections with 2017 counts to reflect 2019 conditions. Exhibits 5 and 6 identify the count data utilized for each study intersection and illustrate the resulting Existing (2019) morning and evening peak hour intersection volumes. ADT volumes are estimated using the formula below for each intersection leg (consistent with 2018 Travertine Specific Plan TIA, prepared by Urban Crossroads, Inc.) and compared to the 2017 ADT’s with 2.66% growth to reflect 2019 conditions, where 2019 counts are unavailable.  Weekday PM Peak Hour (Approach Volume + Exit Volume) x 12 = Leg Volume ANALYSIS SCENARIOS Consistent with Engineering Bulletin #06‐13, the following analysis scenarios are proposed for this traffic study:  Existing (2019)  Existing Plus Project (E+P)  Existing Plus Ambient Growth Plus Project (E+A+P)  Existing Plus Ambient Growth Plus Cumulative Projects, with and without Project for each of the following phases: o Project Phase 1 (2021) o Project Phase 2 (2023) o Project buildout (Phase 3, 2026) o Project buildout (Phase 3, 2026) – Special Event  General Plan buildout (2040) Without Project Conditions – establishes future year baseline to evaluate the proposed Project  General Plan buildout (2040) With Project Conditions – represents future year baseline traffic conditions with the proposed Project In accordance with Engineering Bulletin #06‐13, improvements fully funded by the City of La Quinta’s Capital Improvement Program (CIP) will be assumed to be in place for long range future conditions. Improvements fully funded by the City’s CIP, the Development Impact Fee Program (DIF) and the Transportation Uniform Mitigation Fee Program (TUMF) are assumed to be in place for Opening Year Cumulative conditions. LEVEL OF SERVICE (LOS) CRITERIA Per Engineering Bulletin #06‐13, the following LOS criteria will be utilized for study area intersections: Intersection Type LOS Criteria Signalized Intersection LOS “D” or better All‐way Stop Controlled Intersection LOS “D” or better for all critical movements Cross‐Street Stop Controlled Intersection LOS “E” or better for the side street Mr. Steve Libring City of La Quinta January 29, 2020 Page 5 12615‐06 Revised Scope.docx The City of La Quinta has established LOS “D” as the minimum level of service for its street segments. PREFERRED ANALYSIS METHODOLOGY The study area intersections will be analyzed using the Highway Capacity Manual (HCM) 6th Edition methodology. The parameters provided in Attachment 2 of Engineering Bulletin #06‐13 will be utilized for the purposes of this analysis, unless directed otherwise. CUMULATIVE DEVELOPMENT PROJECTS It is requested that the City of La Quinta Planning Department review the cumulative projects shown on Exhibit 7 and listed on Table 5. CUMULATIVE GROWTH VOLUMES The background (non project) Opening Year Cumulative traffic projections will be determined by interpolating between the existing traffic volumes and the year 2040 City and/or CVAG traffic projections. YEAR 2040 TRAFFIC FORECASTS The Year 2040 forecast volumes are based upon an updated version of the Riverside County Transportation Analysis Model (RivTAM) which became available in the CVAG region during 2016. It is consistent with the SCAG draft 2016 RTP for the Transportation Project Prioritization Study (TPPS) 2040 project. For 2040 conditions, RivTAM projections will be examined to determine additional growth beyond the 2035 peak hour intersection volumes identified in the 2012 traffic study prepared by Iteris for the La Quinta General Plan Update. Where necessary, the resulting 2040 volumes estimates will be adjusted to achieve flow conservation, reasonable growth, and reasonable diversion between parallel routes. SPECIAL ISSUES The following issues will also be addressed as part of the TIA:  Site Access Evaluation: Recommendations regarding site access and queuing analysis will be included in the traffic study. It is anticipated that the project will be required to widen Avenue 58 frontage. Eastbound left turn capacity will be evaluated along Avenue 58 approaching Madison Street. Project fair share participation in signal improvements will also be determined.  Jefferson & Avenue 52 Improvements: The revised TIA will now include recommended improvements at Jefferson Street / Avenue 52 for relevant analysis scenarios, based upon discussion with City staff and their consultants.  Interim Year Project Share Estimates: The revised TIA will include fair share calculations for interim year scenarios (as opposed to cumulative long range conditions), based upon the City consultant request. Mr. Steve Libring City of La Quinta January 29, 2020 Page 6 12615‐06 Revised Scope.docx  Vehicle miles traveled (VMT): Consistent with the Office of Planning and Research (OPR) updates to CEQA guidelines which are responding to Senate Bill 743 (SB 743), VMT estimates for the Project will be calculated. Potential mitigation measures and estimated effectiveness in reducing VMT in terms of percentage reduction of VMT for each measure will be identified in the traffic study.  Special Events: The applicant anticipates the potential occurrence of special events at this location involving attendance of not‐to‐exceed 2,500 guests per day arriving or departing on Saturdays (up to 4 events per year). In order to estimate background mid‐day Saturday peak hour volumes in the Project study area, weekday PM peak hour counts will be adjusted. The adjustments will be based upon a sampling of four Saturday intersection counts (between 10:00 AM and 2:00 PM) in the study area. Table 6 shows the Saturday Project trip generation during a special event based on 2,500 guests per day at the Wave Pool facility and approximately 25% of the guests arriving or departing during the arrival or departure peak hour. Weekend rates for other on‐site land uses represent typical Saturday rates. As shown on Table 6, the proposed Project is anticipated to generate a net total of 8,932 trip‐ends per day on a Saturday during a special event with 906 vehicles per hour (VPH) during the arrival peak hour and 884 vph during the departure peak hour. Traffic management plan features will be identified for the typical Project special event (2,500 guests). Exhibit 8 shows a high‐level event operations planning framework which will also be included in the revised TIA as part of the discussion of future traffic control plan refinements for special events.
