TJ KM Transportation Consu Itants Existing plus Proposed Project Conditions Project Proposal The Assisted Living Facility proposed by Fountain Square Development West is a senior residential project to be developed on two parcels in the southwest quadrant of the intersection of EI Camino Real and Oakwood Drive in the City of Redwood City, California. Currently,the parcels include a jewelry store and an unoccupied restaurant on the EI Camino Real frontage, and a vacant lot on the southwest end of the site. The proposed project consists of demolishing the existing structures and constructing 45 assisted living units on the site,to accommodate a maximum of 60 residents and beds. According to the project site plan, a new driveway will be provided on Oakwood Drive approximately 225 feet west of EI Camino Real. New curb,gutter, and sidewalk will be constructed along the entire project frontage on Oakwood Drive and EI Camino Real, and pedestrian walkway connections between the project's building access points and the new public sidewalk on Oakwood Drive will also be provided. The project also proposes vacation of an existing easement that had been reserved for a possible right-turn lane on eastbound Oakwood Drive. Project Trip Generation TJKM developed estimated trip generation for the proposed project based on the published trip generation rates from the Institute of Transportation Engineers' (ITE) publication Trip Generation (8th Edition). Compared with most residential developments, senior assisted living residential units typically generate fewer peak hour trips,for several reasons. The senior residents of assisted living facilities typically are not able to drive and no longer own vehicles, as they move into such facilities because they need assistance with several daily living activities (e.g. eating, bathing, dressing, mobility, etc.). The occasional trips they may take with others driving typically occur less often during peak hours because they are not commuting, and trips for health care appointments, shopping, recreation, and other purposes can be made at more flexible times of the day. Most of the trips to and from assisted living facilities are employees,visitors, and deliveries, and the employee shift starting and ending times typically do not coincide with the a.m. and p.m. commute peak hours on the adjacent street network. However,the mid-afternoon shift change time that results in the facilities' peak p.m. trip generation hour typically coincides with the 3:00 to 4:00 p.m. school dismissal peak hour. It should be noted that the ITE trip generation rate for Assisted Living (Code 254) reflects these factors and also includes expected a.m.,facility (and school) p.m., and commute p.m. peak hour trips that would be generated by facility employees, deliveries, and any visitors to the senior residences. The estimated net project trip generation also reflects a credit for trips currently generated by the existing jewelry store on the project site, because those trips are already included in the existing traffic volumes collected for analysis of the study intersection and roadway segment. TJKM observed traffic entering and exiting the jewelry store parking area during the school p.m. and commute p.m. peak periods on a typical weekday in late February 2012 to determine the existing site trip generation for those periods. The I I trips that TJKM observed during the school p.m. peak hour corresponds approximately with the I 3 peak hour trips observed by Hexagon Transportation Consultants (Hexagon) in 2008 for a traffic study of a development previously considered at the site. The jewelry store business hours are I 0:00 a.m.to 5:00 p.m., and only one trip was observed accessing the site during the a.m. and commute (5:00 to 6:00) p.m. peak hours, consisting of one employee entering in the a.m. observed by Hexagon and one leaving in the commute p.m. observed by TJKM. Based on the peak hour counts of jewelry store trips, TJKM conservatively estimated its existing daily trip generation by assuming that the average number of trips per hour for the seven hours the store is open is approximately half the number of trips observed as the store's peak hour, which results in an estimated 40 trips per day.
