The development is proposed to be an addition to the existing French Hospital located along Johnson Avenue between Lizzie Street and Ella Street. The addition is proposed to include a 90,000 square-foot wing tower with 82 beds, a 1,000 square foot chapel, a 4,300 square- foot hospital lab, and a parking structure located over an existing parking surface lot. The Focused Transportation Study will be prepared based on the City of San Luis Obispo Multimodal Transportation Impact Study Guidelines (March 2015). This study will assess trip generation, distribution, and assignment of the proposed project on the study area circulation system. If necessary, feasible mitigation measures for identified project-generated traffic impacts will be recommended in accordance with applicable performance criteria. Task 1 – Data Collection/Site Visit Available count data provided by the City will be evaluated and data collection will be conducted in order to address any gaps in locations and data age. It is anticipated that new data will be collected given the age of the available data. Michael Baker will utilize a contractor to collect existing classified traffic count volumes at the identified study intersections on a typical weekday (Tuesday, Wednesday, or Thursday) while local schools are in-session. Count classifications will include cars, trucks/buses, bicyclists, and pedestrians. Automatic traffic recorder counts are not anticipated to be required as part of this effort. It is projected that data collection will include intersection turning movement counts at the following locations and times: 1) Johnson Avenue @ Lizzie Street – 4:00 PM to 6:00 PM 2) Johnson Avenue @ Ella Street – 4:00 PM to 6:00 PM 3) Johnson Avenue @ Sydney Street – 7:00 AM to 9:00 AM Michael Baker will visit the traffic study area to document existing conditions including intersection control, traffic signal phasing, roadway cross-section, speed limits, parking restrictions, intersection approach lanes, etc. The traffic analysis will include graphics documenting the existing intersection roadway geometry, and the analysis will utilize existing geometric conditions to establish a baseline for current operations. Task 2 – Traffic Forecasts Volume Forecast Scenarios The analysis for the proposed project will forecast traffic volumes for two (2) scenarios: 1. Existing 2. Existing + Project Phasing of the project is not anticipated, therefore only one project phase will be analyzed as part of this study. Near term and long-range analyses are not anticipated to be required. 2 Page Analysis Time Periods Traffic volume forecasts will be developed for analysis time period identified at each of the study intersections: 1) Johnson Avenue @ Lizzie Street – PM Peak Hour 2) Johnson Avenue @ Ella Street – PM Peak Hour 3) Johnson Avenue @ Sydney Street – AM Peak Hour Proposed Project Traffic Forecast Michael Baker will derive daily and peak hour forecast project trip generation using trip generation rates contained in Trip Generation (Institute of Transportation Engineers, 10th Edition) or other source as directed by agency staff. Trip distribution will based upon the existing count data collected at the hospital site driveways as well as an examination of travel trends in the area. A trip generation technical memorandum will be prepared at the initial stage of the study in order to confirm trip generation and trip distribution assumptions with City staff prior to analysis and completion of the study. The trip generation memorandum will discuss items including pass-by trips and internal capture as appropriate. Conversion into passenger car equivalents is not anticipated given the nature of the proposed development, however the data collection program will include a heavy vehicle classification in order to obtain a truck percentages by movement. Task 3 – Operations and Impact Analysis The traffic operations analysis to assess conditions at the two (2) signalized study intersections will be conducted using the Highway Capacity Manual (HCM) analysis methodologies for each analysis scenario during the PM Peak Hour. The City- provided Synchro model will be utilized to conduct the intersection analysis. The Synchro model will be validated at the study intersections prior to conducting the analysis and updated or calibrated as necessary. Vehicular, bicycle, and pedestrian level of service will be documented at each of the study intersections. Queuing analysis will also be prepared for each analysis scenario. Roadway segment analysis is not anticipated to be required as part of this effort. Additionally, an AM Peak Hour pedestrian level of service analysis will be conducted for the existing crosswalk located at the intersection of Johnson Avenue and Sydney Street. The City of San Luis Obispo Multimodal Transportation Impact Study Guidelines (March 2015) will be utilized to obtain the appropriate thresholds of significance. If the analysis indicates the proposed project will significantly impact a study intersection based upon the appropriate threshold, feasible mitigation measures will be recommended to eliminate or reduce the impact in accordance with the guidelines. The analysis will document forecast operating conditions after implementation of recommended mitigation measures, if necessary. A fair-share fee calculation will be conducted for any mitigation measures identified. Task 4 – Traffic Study Report The methodologies and results of the traffic analysis shall be documented and summarized in a written multimodal transportation impact study. The study will include the appropriate maps, exhibits, and tables required for comprehensive documentation. A preliminary draft report will be submitted to the City for review and comment. This scope of work assumes one revision to the draft report based on City comments. 3 Page FEE SCHEDULE The anticipated schedule is as follows: OPTIONAL TASKS Parking studies, conceptual and final design plans, and traffic signal modification plans are excluded. Additional tasks or the analysis of additional intersections not included in this scope of work can be accommodated for fee in addition to the fee associated with this scope of work based on direction from the City.
