Transportation Analysis Summary

• Parent, student and staff travel surveys
• Estimated future parking demand
• Location of on-site transportation facilities (e.g., accessible walkways, bus

and parent pick-up and drop-off)

• Traffic analysis, speed and crash study around school site
• Off-site infrastructure improvements to support safe access and

circulation for all travel modes

• School programs that support more walking, biking, carpooling, bus and

transit use

Parking Requirements (Zoning Code): Middle School 173 Elementary School 119 Total APS Requirement 292

Assumption: Peak parking demand for community uses on site (i.e. community center, theater) does not

• verlap with peak demand for school uses. Thus, separate zoning requirements for those uses are not

included in this total.
