Appian Way housing proposal: access and safety deserve close scrutiny
Union City is reviewing a proposal for 80 homes at the eastern end of Appian Way, above the Seven Hills neighborhood. The approximately 98.7-acre site would contain about 18.4 acres of housing and associated roads.
Mission Peak Conservancy asks the City to provide clear answers about wildfire evacuation, road capacity, and protection of the surrounding open space before approving the project.
Road access
Demonstrate that the entire emergency route through O’Connell Lane will be usable, maintained, and completed before occupancy.
Traffic congestion
Explain how additional traffic will affect neighborhood streets and already-constrained Mission Boulevard intersections.
Lasting accountability
Identify who pays for road improvements, fuel management, and enforcement that keeps emergency access clear.
