1815 13TH ST SEPA 016 - 013 - PRMC NEW CLINIC BUILDING Traffic Report 2025-04-22

Transportation Impact Analysis Providence Regional Medical Center New Medical Clinic Building and Parking Lot Reconfiguration April 2016 In addition to the construction impacts identified above, with the parking lot reconfiguration project, a portion of the existing parking would be removed for site preparation. During this period, approximately 166 to 191 spaces would be eliminated resulting in 125 to 150 remaining. Existing peak period observations indicate that the parking lot is currently over capacity with 100 percent of the spaces filled and approximately 5 to 6 vehicles parking in undesignated spaces for a total peak parking demand of 322 parking spaces. Construction would result in a shortfall of approximately 172 to 197 parking spaces. The site preparation phase is anticipated to occur during the summer period when the census of the hospital is typical low and fewer employees are on-site due to the lower hospital census and summer vacations. Historical peak parking demand for Campus off-street parking facilities (excluding the parking lot that would be under construction)was reviewed for 2014 and 2015 during the summer period between June and August to understand potential parking availability. A review of the campus peak parking demand shows that during peak hours there is an average of 250 parking spaces available. Based on this availability, the existing Campus parking facilities could accommodate the 172 to 197 displaced vehicles during construction. 12th Street Alternative Access Evaluation As part of the conditions of approval, PRMC is required to provide a traffic analysis showing the advantages and impacts for site access via 12th Street. The proposal provides access via the existing 13th Street access; however, it does not preclude future access via 12th Street. A summary of 12th Street site access evaluation is provided below. Advantages • Traffic impacts to 13th Street would be reduced by shifting some of the site traffic to 12th Street. • A driveway access at 12th Street would operate at LOS A during the weekday PM peak hour under future 2022 with-project condition. • Provision of a secondary access to the project site would improve driveway operations at the proposed 13th Street site access. Impacts • Both 12th and 13th Street are served by traffic signals at Broadway. The intersections along Broadway are anticipated to meet the City's LOS standard with provision of access along 12th Street. • Traffic volumes along 12th Street would increase resulting in additional impacts to the residents and businesses along this street including additional vehicle and pedestrian conflicts. • The Main Campus for PRMC is currently along 13th and 14th Street. Access along 12th Street would be secondary and only serve the proposed project site. Locating this access could be confusing to visitors and may result in circuitous travel within the adjacent neighborhood. • Traffic may increase along the existing alley adjacent to the project site with access along 12th Street. • If parking areas for the proposed project site become full, drivers may be more likely to park along 12th Street and in the neighborhood with the new connection to the site at 12th Street.
