The current project description includes a proposed office building with approximately 14,000 square feet of floor area and a reconfigured parking area for common use with the existing Church of Christ and Frankie,Johnnie, and Luigi restaurant. The shared parking agreement site is directly across Donlon Way from the City's public Heritage Park, and is generally bounded by Dublin Boulevard on the north, Donlon Way on the west, the existing Shell gas station on the east, and the proposed 54-lot residential development (not a part of the shared parking agreement) to the south. The general purpose of the analysis is to see how the peak parking demand of the existing and proposed uses included in the proposed parking easement agreement for the site compares with the proposed parking supply. Because City Zoning Ordinance requirements for parking only consider different land uses as separate components, not accounting for the hourly and day-of- week variations in parking demand for each of the proposed land uses, allowances must be made for such peak demand variations among mixed uses, as described in this report. The analysis presented in this letter report demonstrates that the proposed parking supply, which is 13 spaces or ten percent less than the supply otherwise required by the City's Zoning Ordinance, can more than accommodate the expected peak demand. Pleasanton 3875 Hopyard Road The following proposed parking supply data is based on the site plan by Carlson, Barbee& Gibson Suite 200 Civil Engineers dated May 20, 2013.

TJKM Mr. Scott L Stringer Transportation September 9, 2013 Consultants Page 5 Conclusions Comparing the proposed 123-space on-site supply with the peak supply needed as shown in Table II yields the following conclusions: • For the weekday peak, 86 of the 123 on-site spaces would be needed during the peak hour parking demand at 7:00 p.m. on Wednesday, which provides a surplus parking supply of 37 spaces, or 30 percent of the on-site supply. • For the weekend peak, 74 of the 123 on-site spaces would be needed during the peak hour parking demand at 1:00 p.m. on Sunday. This provides a surplus parking supply of 49 spaces, or 40 percent of the on-site supply. Based on this analysis, the expected peak parking requirement is 86 spaces, where the total proposed on-site parking supply is 123 spaces. Therefore, this 37-space surplus of on-site parking supply over the peak supply needed strongly indicates that the proposed parking supply is reasonable to fully accommodate the project's parking and on-site circulation needs. We will be happy to discuss any questions or comments you may have regarding these findings. Very truly yours, Richard K.
