Council hears traffic, parking and event management concerns for Northpointe plan

Alpharetta staff and the applicant told the council that the project would generate large volumes of traffic at buildout and during major events and that the applicant's shared‑parking study anticipates peak event demand will outstrip on‑site parking.

Traffic engineer Brian Bullock (speaker 5) said the site‑wide study evaluated 14 intersections and three scenarios and recommended turn‑lane, signal and timing changes plus a formal event transportation plan. "The total trips in and out about that time of day would be about 5,000 a trip or so," he said to illustrate event peaks; the study estimated roughly 12,302 parking spaces would be required at peak event times, versus about 7,375 on a typical non‑event day. Council members asked who would guarantee off‑site parking for arena events; staff and the applicant said they would require preliminary off‑site parking agreements and that condition 33 would require approvals prior to land‑disturbance permits.

Opponents and some councilmembers said the 15‑minute‑walk ring of purported 10,000 off‑site spaces is not a substitute for mapped, controlled agreements and safe pedestrian routes. Council conditioned approval on submission and staff review of preliminary on‑site and off‑site parking agreements, as well as event‑day transportation plans and public‑safety staffing requirements, before major permits are issued.
