The project proposes to construct a 19,427-square-foot (sf) sanctuary with 1,250 seats, a 6,004 sf parish center, 4,850 sf of meeting rooms, a 16,024 sf parish hall, a 23,956 sf courtyard, and a 19,346 sf garden. These uses will replace the existing 4,770 sf sanctuary with 396 seats, 2,420 sf of office space, and 3,700 sf of courtyard space, which will be demolished as part of the project. The project will retain the two existing access driveways and add a third driveway connecting to Jaguar Way, which would be gated and only used on weekends. The combined trip generation for this project and the residential project located on the southern portion of the lot is anticipated to be lower than the trip generation for the Master Plan analyzed as part of the Armstrong Ranch Development Project Environmental Impact Report in June 2002. The trip generation for the Church project is lower than the City’s threshold for requiring a traffic impact analysis. However, the traffic impacts of the project were analyzed at the adjacent intersections during the a.m. and p.m. peak hours of the street as well as during the Sunday peak hour of traffic generation. All study area intersections are anticipated to operate at a satisfactory LOS in the weekday a.m. and p.m. peak hours and the Sunday morning peak hour with the addition of project traffic. LSA considered special events and determined the effect of these events would be no greater than the analyzed Sunday services. LSA examined the project access driveways and found that the driveway and gated access would function adequately without interference to the arterial street system. Special consideration was given to the interaction with traffic at the nearby school. The gate on the southern driveway will remain closed on weekdays, so no Church traffic would interact with school traffic on Jaguar Way. The southern leg of Raitt Street from Alton Avenue is used as an unofficial drop-off area. Church traffic does not create an impact. In fact, the proposed project will create a wider and more defined turn-around area on Raitt Street should drop-offs continue. But Raitt Street is not wide enough for a parking lane and a driving lane and drop-off activity may create friction on Raitt Street. Based on the results of this TIA, the proposed development of the Christ Our Savior Catholic Parish could be implemented without significantly impacting the nearby circulation system. 3-48
