4. Existing Travel Behaviors and Parking Demands Current travel behavior for the people arriving at the County Campus was derived from data provided by the County and from special travel surveys conducted by Perteet Engineering in August 2001. Four separate groups were identified from this data for evaluation of parking and traffic demands: • Employees • Jurors • Customers and Visitors • Fleet vehicles 4.1 Employees Travel behavior for employees was available from the Commute Trip Reduction (CTR) records submitted each year by the County. The County has a relatively good CTR program. However, it was found that on an average day about 71% of County employees (including so-called '`exempt" employees) drive alone in single occupant vehicles (SOVs) while about 17%carpool or vanpool, 5% take the bus, 3% bicycle or walk, and 3% of employees do not travel to the campus at all on that day due to sickness, vacation, out-of- town business, or telecommuting. This data was collaborated by the Perteet Engineering travel surveys conducted in August, 2001. Employee parking demand calculations were made on the basis of these travel patterns, including discounts for carpools and vanpools. In calculating the employee parking demands, the number of employees at the jail was discounted by 50% to reflect the fact that all of them do not work on the weekday shift. It is estimated that about 1.190 parking spaces are required today to meet employee demands while only about 450 parking spaces are provided for employees in County owned parking facilities. This means that about 740 employees use other parking facilities in the downtown area including about 350 who park on the street according to our surveys. 4.2 Fleet Vehicles The County currently uses about 270 parking spaces for fleet vehicles. Many of these vehicles are located in leased space at the Everpark garage. Some of these vehicles might be used by employees and may result in some double counting of parking demand. 4.3 Jurors There are two County-owned parking lots set aside for jurors and additional space is rented from the Wells Fargo garage as it is needed. Jurors are provided parking passes in the mail when they are summoned for jury duty. All jurors surveyed reported driving in single occupant vehicles (SOV). The average-day parking demand for jurors in 2001 is about 90 parking spaces. The needs are about 40% higher on Mondays when jurors are first summoned and about 20% less on Fridays when fewer trials are still in session. CRI Transportation Impact Analysis Page 8 June 2002
