V4 10 Traffic Impact Study Rev 2 1 27 2023

Traffic Impact Study Proposed Continuing Care Retirement Community – West Orange FUTURE CONDITIONS Traffic volumes and operational analyses were developed for both the No Build and Build conditions. The No Build conditions provide a baseline for assessing the impact of site development traffic on the roadway system. The process of developing the No Build and Build traffic volumes and the subsequent analyses is outlined below. Regardless of whether the subject site is developed or not, traffic volumes on the surrounding roadways are expected to increase as a result of developments throughout the region. A growth rate for roadways within the study area was obtained from the NJDOT Annual Background Growth Rate Table, which indicates a growth rate of 2% per year. Future No Build traffic volumes were developed by applying the background growth rate of 2% for six (6) years to the study area roadways existing traffic volumes in order to coincide with the anticipated 6-year buildout. Figure 3, in Appendix A, shows the No Build traffic volumes. Traffic Generation Trip generation projections for The Project were prepared utilizing trip generation research data as published under Land Use Code (LUC) 620 – Nursing Home for the existing facility and using LUC 255 – Continuing Care Retirement Facility for the proposed facility as published in the Institute of Transportation Engineers’ (ITE) publication, Trip Generation, 11th Edition. This publication sets forth trip generation rates based on traffic counts conducted at research sites throughout the country. ITE defines a Continuing Care Retirement Community as follows: “A continuing care retirement community (CCRC) is a land use that provides multiple elements of senior adult living. A CCRC enables a resident to transition in place from independent living to increased care as the medical needs of the resident change. Housing options may include various combinations of senior adult housing (both single-family and multifamily), congregate care, assisted living, and nursing home. The community may also contain special services such as medical, dining, recreational, communal transportation, and some limited, supporting retail facilities. A CCRC is usually a self-contained village.” Based on the above definition, LUC 255 is clearly

medical, dining, recreational, communal transportation, and some limited, supporting retail facilities. A CCRC is usually a self-contained village.” Based on the above definition, LUC 255 is clearly the most appropriate land use to describe the improved facility that is proposed.
