Parking Assessment
Background
An assessment of the estimated parking demand for the proposed warehouse use was completed based on
your email response to Lisa Morrell Ehli, Synthesis PLLC (dated June 6, 2019) shown below:
Parking Demand
The peak parking demand for the proposed warehouse use was estimated based on parking generation
rates documented in the Institute of Transportation Engineers (ITE) Parking Generation (5th Edition).
Specifically, Land Use Code (LUC) 150 (Warehousing) was used in the parking analysis. The following
Table 1 summarizes the estimated peak parking demand for the project.

1. Per Institute of Transportation Engineers (ITE) Parking Generation (5th Edition).
As shown in the table above, the peak parking demand for the proposed 40,059 SF warehouse use, is 16
vehicles. The estimated peak parking demand would be accommodated by the 27 stall on-site parking
supply. As a result, no parking spillover is anticipated with the proposed change in use.
